DETAILED DESCRIPTION

[0080] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 11 A refrigerator 200 according to an embodiment of the first aspect of the utility model is described. The refrigerator 200 may be a vehicle refrigerator for use in a vehicle (not shown). In the following description of the present application, the refrigerator 200 is used in a thermal management system 100 of a vehicle as an example for detailed description.

[0081] like Figure 1 and Figure 2As shown, the refrigerator 200 according to the embodiment of the first aspect of the utility model includes a refrigerator heat exchange module 201.

[0082] Specifically, the refrigerator heat exchange module 201 includes a direct heat exchanger 2011, an indirect heat exchanger 2012 and an energy storage material piece (not shown in the figure). The direct heat exchanger 2011 and the indirect heat exchanger 2012 are connected in series to form a first refrigerant flow path. The energy storage material piece is suitable for heat exchange with the indirect heat exchanger 2012. When the refrigerator heat exchange module 201 is working, at least one of the direct heat exchanger 2011 and the energy storage material piece is used for heat exchange.

[0083] For example, in Figure 1 and Figure 2 In the example, when the refrigerator 200 is working, the refrigerant passes through the first refrigerant flow path, and the refrigerant uses part of the energy to cool or heat the items through the direct heat exchanger 2011, and stores the other part of the energy in the energy storage material through the indirect heat exchanger 2012. When the refrigerator 200 has a heat exchange demand, such as a cooling demand, the direct heat exchanger 2011 can be selected to work for heat exchange or the energy storage material can be selected to work for heat exchange according to the actual state of the refrigerator 200.

[0084] The working states of the refrigerator 200 include the following situations:

[0085] First, when the refrigerator 200 has no cooling or heating demand, and the energy storage material component of the refrigerator 200 has no energy storage demand (ie, the temperature of the energy storage material component is lower than the target temperature such as -10°C or higher than the target temperature such as 60°C), the first refrigerant flow path is closed.

[0086] Second, when the refrigerator 200 has no cooling or heating demand, and the energy storage material part of the refrigerator 200 has energy storage demand (i.e., the temperature of the energy storage material part is higher than the target temperature such as -10°C or lower than the target temperature such as 60°C), the first refrigerant flow path is opened, and the direct heat exchanger 2011 does not work, and passes through as a flow channel. The refrigerant exchanges heat with the energy storage material part through the indirect heat exchanger 2012, so that the energy storage material part stores energy, such as cold or heat.

[0087] Third, when the refrigerator 200 has a cooling or heating demand, the refrigerator 200 can use the energy storage material for cooling or heating (that is, when the temperature of the energy storage material is lower than the target temperature such as 0°C or higher than the target temperature such as 45°C), the first refrigerant flow path is closed.

[0088] Fourth, when the refrigerator 200 has a cooling or heating demand, and the refrigerator 200 cannot use the energy storage material for cooling or heating (that is, the temperature of the energy storage material is higher than the target temperature such as 0°C or lower than the target temperature such as 45°C), the first refrigerant flow path is opened, and the refrigerant uses part of the energy to cool or heat the items through the direct heat exchanger 2011, and stores the other part of the energy in the energy storage material through the indirect heat exchanger 2012.

[0089] In this way, by setting the indirect heat exchanger 2012 and the energy storage material, when the refrigerator 200 is in use, the food and beverage items and the energy storage material in the refrigerator 200 can be heat exchanged at the same time, that is, the energy (for example, cold or heat) of the refrigerant is used for heat exchange in the direct heat exchanger 2011, and the excess energy is stored in the energy storage material, or the energy can be stored at the energy storage material for use, which increases the energy demand of the refrigerator 200, effectively increases the heat exchange amount, and improves the cooling or heating speed of the refrigerator 100 (it should be noted that when the energy storage material is a cold storage material, the refrigerator 100 can be used for cooling; when the energy storage material is a heat storage material, the refrigerator 100 can be used for heating), so as to meet the use of the refrigerator 100 and the needs of the occupants. The refrigerator 200 can be cooled or heated by the direct heat exchanger 2011 or the cold storage material, enriching the heat exchange mode of the refrigerator 200 and improving the reliability of the heat exchange of the refrigerator 200.

[0090] In addition, the refrigerator 200 can also be used in different states, reducing the loss of energy in the refrigerant and improving the utilization rate of energy. In addition, when the refrigerator 200 uses the thermal management system 100 of the vehicle, the energy demand of the refrigerator 200 can be met, and the difference between the heat exchange amount of the refrigerator heat exchange module 201 and the heat exchange amount of the air conditioning module 1 can be reduced, so that the evaporation pressure and energy mismatch between the functions of different temperature control when the refrigerator heat exchange module 201 and the air conditioning module 1 are used at the same time can be solved. Moreover, the distribution of the refrigerant is more reasonable, which effectively guarantees the cooling or heating speed of the refrigerator heat exchange module 201, meets the needs of users, and effectively guarantees the cooling or heating capacity of the air conditioning module 1, so that the refrigerator 200 can be used normally, and the thermal management system 100 is more matched as a whole, and each component of the thermal management system 100 (for example, the evaporator, the compressor 11, the condenser and the pipeline, etc.) is relatively matched, thereby ensuring the normal use of the refrigerator 200 and the normal operation of the thermal management system 100.

[0091] According to the refrigerator 200 of the utility model, the refrigerator 200 can cool or heat the articles through direct heat exchanger 2011, and can also store energy in the energy storage material part through indirect heat exchanger 2012, and use the energy storage material part to cool or heat the articles, thereby increasing the energy demand of the refrigerator 200, effectively increasing the heat exchange amount, and improving the cooling or heating speed of the refrigerator 100, so as to meet the use of the refrigerator 100 and the needs of the passengers. In addition, it can also meet the use of the refrigerator 200 in different states, reduce the energy loss in the refrigerant, and improve the utilization rate of energy. In addition, when the refrigerator 200 uses the thermal management system 100 of the vehicle, the difference between the heat exchange amount of the refrigerator heat exchange module 201 and the heat exchange amount of the air conditioning module 1 is reduced, so that the evaporation pressure and energy mismatch between the functions of different temperature control when the refrigerator heat exchange module 201 and the air conditioning module 1 are used at the same time can be solved, and the cooling or heating speed of the refrigerator heat exchange module 201 is effectively guaranteed, so that the refrigerator 200 can be used normally, and the thermal management system 100 is more matched as a whole, and the thermal management system 100 can be operated normally.

[0092] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 , the refrigerator heat exchange module 201 further includes an energy storage material heat exchanger 2013, and at least one of the energy storage material heat exchanger 2013 and the indirect heat exchanger 2012 is suitable for heat exchange with the energy storage material. Figure 1 and Figure 2 In the example, the energy storage material heat exchanger 2013 contacts the energy storage material piece for heat exchange, and the indirect heat exchanger 2012 contacts the energy storage material piece for heat exchange.

[0093] With such a configuration, when the energy storage material heat exchanger 2013 performs heat exchange with the energy storage material element, the energy storage material element directly cools down or heats up the items in the refrigerator 200 at the energy storage material heat exchanger 2013 to meet the needs of customers in summer or winter. When the indirect heat exchanger 2012 performs heat exchange with the energy storage material element, the refrigerant in the indirect heat exchanger 2012 performs heat exchange with the energy storage material element to reduce the temperature of the energy storage material element, that is, the excess energy can be stored in the energy storage material element, so that the energy storage material element can cool down or heat up the items in the refrigerator 200 to maintain the temperature required for cooling or heating the refrigerator 200, so that during the operation of the refrigerator 200, the refrigerator 200 is in a cooling or heating state, thereby improving the performance of the refrigerator 200.

[0094] Optionally, refer to Figure 3 , Figure 4 and Figure 5The direct heat exchanger 2011 and the energy storage material heat exchanger 2013 respectively include two manifolds 206 and a plurality of flow guide components 207. The two manifolds 206 are opposite to each other in the front-to-back direction. One of the two manifolds 206 is provided with an inlet 2061 and an outlet 2062. The plurality of flow guide components 207 are located between the two manifolds 206. The plurality of flow guide components 207 are spaced apart in the up-down direction. The plurality of flow guide components 207 and the two manifolds 206 together define a flow channel arranged in an S shape. In the description of the present utility model, the meaning of "plurality" is two or more. It should be noted that in the present application, the direct heat exchanger 2011 and the energy storage material heat exchanger 2013 have the same structure, and the corresponding inlet 2061 and outlet 2062 can be adjusted accordingly according to the installation connection relationship.

[0095] Reference Figure 3 and Figure 4 The guide assembly 207 includes a plurality of harmonica tubes 2071 and a plurality of partitions 2072, the plurality of harmonica tubes 2071 and the plurality of partitions 2072 are alternately arranged in the left-right direction, the harmonica tube 2071 extends in the front-back direction, one end of the harmonica tube 2071 is connected to one of the two collecting pipes 206, the other end of the harmonica tube 2071 is connected to the other of the two collecting pipes 206, the plurality of harmonica tubes 2071 are arranged at intervals in the left-right direction, each harmonica tube 2071 is formed with a plurality of through holes 2071c arranged at intervals in the up-down direction, the plurality of through holes 2071c extend in the front-back direction through the front and rear ends of the harmonica tube 2071, and the partition 2072 is located between two adjacent harmonica tubes 2071.

[0096] For example, in Figure 3 , Figure 4 and Figure 5 In the example, the direct heat exchanger 2011 is used as an example for detailed description. The cross-sectional shape of the partition 2072 along the horizontal direction is roughly wavy. The partition 2072 extends along the front-to-back direction. One side of the partition 2072 along the left-to-right direction abuts against the side of the adjacent harmonica tube 2071. The outlet 2062 of the direct heat exchanger 2011 is connected to the inlet of the indirect heat exchanger 2012. The inlet 2061 of the direct heat exchanger 2011 is the inlet of the direct heat exchanger 2011, and the outlet 2062 of the direct heat exchanger 2011 is the outlet of the direct heat exchanger 2011. Figure 7As shown, after the refrigerant flows into the front end manifold 206 along the inlet 2061, it flows into the rear end manifold 206 along the multiple harmonica tubes 2071 of the guide component 207 adjacent to the inlet 2061, and then flows back to the front end manifold 206 along the multiple harmonica tubes 2071 of another guide component 207 adjacent to the above guide component 207, and then flows into the rear end manifold 206 along the multiple harmonica tubes 2071 of another guide component 207 adjacent to the above guide component 207, and then flows into the rear end manifold 206 along the multiple harmonica tubes 2071 of another guide component 207 adjacent to the above another guide component 207, and repeats in sequence. The flow path of the refrigerant is roughly S-shaped, and finally the refrigerant flows out along the outlet 2062 (the flow path of the refrigerant is shown in FIG. 2 ). Figure 7 The wind (i.e., the flowing air) can pass between two adjacent harmonica pipes 2071 of each guide assembly 207 in a top-to-bottom direction (e.g., Figure 7 In the direction indicated by the arrow C in the figure), the wind passes through the multiple harmonica tubes 2071 and the multiple partitions 2072 of the multiple guide components 207 in sequence.

[0097] With such arrangement, the wind can flow along the up-down direction of the direct heat exchanger 2011, thereby increasing the contact time between the wind and the direct heat exchanger 2011, extending the length of the flow path of the refrigerant in the direct heat exchanger 2011 or the energy storage material heat exchanger 2013, extending the length of the heat exchange path of the refrigerant, increasing the effective distance of heat exchange, and enabling the wind to fully exchange heat with the direct heat exchanger 2011 or the energy storage material heat exchanger 2013, thereby improving the heat exchange capacity of the direct heat exchanger 2011 or the energy storage material heat exchanger 2013, improving the cooling or heating capacity of the refrigerator 200, and further improving the heating or cooling speed of the refrigerator 200, and improving the use effect of the refrigerator 200. In addition, while ensuring that the total heat exchange area remains unchanged, the flat narrow surface of the harmonica tube 2071 (i.e., the plurality of through holes 2017c are arranged in the up-down direction) is used to face the wind, thereby reducing the windward area, facilitating the passage of wind, and facilitating heat exchange. Moreover, the structure of the direct heat exchanger 2011 or the energy storage material heat exchanger 2013 is also reduced, the occupied space is reduced, the structural arrangement of the refrigerator 200 is more compact, and the effective utilization rate of the space in the refrigerator 200 is improved. In addition, the setting of the partition 2072 is not only convenient for wind to pass through, but also can be used to support the harmonica pipes 2071 on the left and right sides of the partition 2072, thereby further improving the structural strength of the harmonica pipes 2071 and extending the service life of the harmonica pipes 2071. Moreover, when the direct heat exchanger 2011 or the energy storage material heat exchanger 2013 is an evaporator, the frost formed on the surface of the direct heat exchanger 2011 or the energy storage material heat exchanger 2013 after the refrigerant exchanges heat with the wind, the direction in which the concave part and the convex part of the wave of the partition 2072 extend is consistent with the direction of the wind flow, so that the frost is more smooth and easy to discharge after melting. However, the present invention is not limited thereto and the arrangement structure of the direct heat exchanger 2011 or the energy storage material heat exchanger 2013 may be adjusted according to the flow direction of the wind.

[0098] According to some embodiments of the present invention, referring to Figure 3 and 4 , the two manifolds 206 include a first manifold 2063 and a second manifold 2064, the first manifold 2063 and the second manifold 2064 are respectively located at the front and rear ends of the plurality of harmonica tubes 2071. The first manifold 2063 includes a first sub-manifold 2063a and a second sub-manifold 2063b, the second manifold 2064 includes a third sub-manifold 2064a and a fourth sub-manifold 2064b, the first sub-manifold 2063a and the third sub-manifold 2064a are connected through a part of the harmonica tubes 2071 of the plurality of flow guide components 207, the third sub-manifold 2064a and the fourth sub-manifold 2064b are connected through another part of the harmonica tubes 2071 of the plurality of flow guide components 207, the first sub-manifold 2063a and the second sub-manifold 2063b are connected to each other, and the third sub-manifold 2064a and the fourth sub-manifold 2064b are connected to each other. The inlet 2061 is formed on a side of the first sub-manifold 2063 a away from the harmonica pipe 2071 , and the outlet 2062 is formed on a side of the second sub-manifold 2063 b away from the harmonica pipe 2071 .

[0099] For example, in Figure 3 and 4 In the example, the first manifold 2063 is located at the front end of the harmonica tube 2071, the second manifold 2064 is located at the rear end of the harmonica tube 2071, the first sub-manifold 2063a and the second sub-manifold 2063b are arranged side by side in the left-right direction, and the third sub-manifold 2064a and the fourth sub-manifold 2064b are arranged side by side in the left-right direction. In this way, the refrigerant flow storage capacity is further increased in the left-right direction, thereby further increasing the heat exchange area between the wind and the refrigerant, and further improving the heat exchange effect of the direct heat exchanger 2011 or the energy storage material heat exchanger 2013. In addition, the first sub-manifold 2063a and the second sub-manifold 2063b support each other, and the third sub-manifold 2064a and the fourth sub-manifold 2064b support each other, which increases the structural strength of the first manifold 2063 and the second manifold 2064, thereby helping to extend the service life of the manifold 206.

[0100] According to some embodiments of the present invention, referring to Figure 4 , Fig.10 and Fig.11The plurality of harmonica pipes 2071 include a plurality of first harmonica pipes 2071a and a plurality of second harmonica pipes 2071b, and the plurality of first harmonica pipes 2071a and the plurality of second harmonica pipes 2071b are arranged at intervals along the left-right direction. The front ends of the plurality of first harmonica pipes 2071a are respectively connected to the first sub-collector pipe 2063a, the rear ends of the plurality of first harmonica pipes 2071a are respectively connected to the third sub-collector pipe 2064a, the front ends of the plurality of second harmonica pipes 2071b are respectively connected to the second sub-collector pipe 2063b, and the rear ends of the plurality of second harmonica pipes 2071b are respectively connected to the fourth sub-collector pipe 2064b.

[0101] For example, in Figure 4 , Fig.10 and Fig.11 In the example, there are two first harmonica pipes 2071a, two second harmonica pipes 2071b, the two first harmonica pipes 2071a are located on the right side of the two second harmonica pipes 2071b, a partition 2072 is provided between the two second harmonica pipes 2071b, a partition 2072 is provided between the two second harmonica pipes 2071b, and a partition 2072 is also provided between the adjacent first harmonica pipes 2071a and second harmonica pipes 2071b. Such a configuration effectively ensures that the refrigerant flows between the first sub-manifold 2063a and the third sub-manifold 2064a along the multiple first harmonica pipes 2071a, and flows between the second sub-manifold 2063b and the fourth sub-manifold 2064b along the multiple second harmonica pipes 2071b, thereby effectively ensuring that the refrigerant can flow in the direct heat exchanger 2011 or the energy storage material heat exchanger 2013, effectively ensuring that the heat exchange can be normal, and thus the thermal management system can be used normally. Moreover, the mutual interference of the refrigerants in the multiple harmonica tubes 2071 can be reduced, the flow is more orderly, and the amount of the refrigerants in the harmonica tubes 2071 is increased to improve the heat exchange effect. The refrigerants in the multiple first harmonica tubes 2071a and the multiple second harmonica tubes 2071b have the same flow direction.

[0102] According to some embodiments of the present invention, referring to Figure 4 and Figure 6-Figure 9, a plurality of openings 2065 are formed on the side of the two manifolds 206 away from the flow guide assembly 207, and the plurality of openings 2065 are arranged at intervals in the up-down direction, and a spacer 2066 is inserted at the opening 2065, so that each manifold 206 is divided into a plurality of spaces in the up-down direction, and the openings 2065 on the two manifolds 206 are arranged in the up-down direction and staggered in the front-back direction. Thus, after the refrigerant flows into the same manifold 206 along the plurality of harmonica tubes 2071, it can flow from the above manifold 206 into the plurality of harmonica tubes 2071 of the flow guide assembly 207 on the adjacent side in the up-down direction, so as to change the flow direction of the refrigerant in the manifold 206 to flow in an S-shape. The outflow port 2062 is located above the inflow port 2061.

[0103] For example, in Figure 4 and Figure 6-Figure 9 In the example, six flow guide components 207 are provided, which are the first flow guide component 207, the second flow guide component 207, the third flow guide component 207, the fourth flow guide component 207, the fifth flow guide component 207 and the sixth flow guide component 207 in the direction from bottom to top. The first sub-collector 2063a and the second sub-collector 2063b opposite to the first flow guide component 207 and the second flow guide component 207 are formed with an opening 2065. The third sub-collector 2064a and the fourth sub-collector 2064b opposite to the second flow guide component 207 and the third flow guide component 207 are formed with an opening 2065. An opening 2065 is formed at the position of the first sub-collector 2063a and the second sub-collector 2063b opposite to the flow component 207 and the fourth flow guide component 207, an opening 2065 is formed at the position of the third sub-collector 2064a and the fourth sub-collector 2064b opposite to the fourth flow guide component 207 and the fifth flow guide component 207, an opening 2065 is formed at the position of the first sub-collector 2063a and the second sub-collector 2063b opposite to the fifth flow guide component 207 and the sixth flow guide component 207, the inlet 2061 is opposite to the first flow guide component 207, and the outlet 2062 is opposite to the sixth flow guide component 207.

[0104] The flow path of the refrigerant is as follows Figure 7 In the direction indicated by arrow B, the flow process of the refrigerant is roughly as follows:

[0105] The refrigerant flows into the first sub-collector 2063a and the second sub-collector 2063b along the inlet 2061, and then flows into the third sub-collector 2064a and the fourth sub-collector 2064b along the two first harmonica tubes 2071a and the two second harmonica tubes 2071b of the first guide component 207. Then the refrigerant flows into the first collector 2063 along the second guide component 207. Under the blocking effect of the partition 2066, the refrigerant flows upward and flows into the third guide component 207, and enters the second collector 2064 again. Under the blocking effect of the partition 2066, the refrigerant flows upward and flows into the fourth guide component 207, and enters the first collector 2063 again. This process is repeated, and the refrigerant enters the fifth guide component 207 and the sixth guide component 207 in turn, and finally flows out along the outlet 2062.

[0106] With such arrangement, the refrigerant flows in a direction from bottom to top, which is opposite to the flow direction of the wind. The refrigerant and the wind exchange heat in countercurrent. After the heat exchange, the temperature of the outlet air is close to the temperature of the refrigerant at the inlet 2061, which can further improve the efficiency of the heat exchange and effectively achieve the effect of energy saving and consumption reduction. In addition, the arrangement of the spacer 2066 can prevent the refrigerant from continuing to flow downward to the harmonica pipe 2071 on the lower side when the refrigerant flows in the manifold 206, so that the refrigerant flows normally along the flow path, ensuring that it can be used normally. In addition, the spacer 2066 and the opening 2065 are simple to arrange and easy to form, thereby improving the production efficiency of the direct heat exchanger 2011 or the energy storage material heat exchanger 2013.

[0107] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 The upper and lower ends of the manifold 206 are provided with cover plates 208, which are tightly matched with the ends of the manifold 206. Thus, when the refrigerant flows through the manifold 206, it is prevented from flowing out along the ends of the manifold 206, thereby improving the sealing performance of the direct heat exchanger 2011 or the energy storage material heat exchanger 2013 and improving the use effect.

[0108] According to some embodiments of the utility model, the refrigerator 200 further includes a box body 202, which has a first accommodating cavity 2021 and a second accommodating cavity 2022. The second accommodating cavity 2022 is located on a side of the direct heat exchanger 2011 and the energy storage material heat exchanger 2013 away from the center of the first accommodating cavity 2021, and the energy storage material part, the direct heat exchanger 2011, the indirect heat exchanger 2012 and the energy storage material heat exchanger 2013 are all arranged in the second accommodating cavity 2022.

[0109] For example, in Figure 1 and Figure 2In the example of , the first accommodating chamber 2021 can be used to accommodate articles. Therefore, the direct heat exchanger 2011 and the energy storage material heat exchanger 2013 can directly exchange heat with the articles in the first accommodating chamber 2021, so that the articles can be cooled and refrigerated or heated, thereby facilitating the cooling or heating speed of the articles and improving the use effect of the refrigerator 200. In addition, it also avoids the energy storage material, the direct heat exchanger 2011, the indirect heat exchanger 2012 and the energy storage material heat exchanger 2013 occupying the space of the first accommodating chamber 2021, thereby increasing the amount that the first accommodating chamber 2021 can accommodate, thereby further improving the use performance of the refrigerator 200.

[0110] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The box body 202 also has an air duct 2023, and the air duct 2023 includes an air outlet 2023a and a return air outlet 2023b. The air duct 2023 is connected to the first accommodating chamber 2021 through the air outlet 2023a and the return air outlet 2023b. The air duct 2023 is located on one side of the second accommodating chamber 2022 close to the first accommodating chamber 2021. The direct heat exchanger 2011 and the energy storage material heat exchanger 2013 are both arranged in the air duct 2023, and a fan 203 is provided in the air duct 2023.

[0111] For example, in Figure 1 and Figure 2 In the example, the direct heat exchanger 2011 is located above the energy storage material heat exchanger 2013. The air in the box 202 flows into the first accommodating chamber 2021 along the air outlet 2023a, and then flows into the air duct 2023 from the return air outlet 2023b under the action of the fan 203. Then the air passes through the direct heat exchanger 2011 and the energy storage material heat exchanger 2013 in turn, and heat exchange occurs, so that the temperature of the air discharged from the air outlet 2023a is relatively low. Such a setting effectively ensures that the air can circulate in the box 202, and the temperature of the air flowing out of the air outlet 2023a is relatively low, so that the temperature inside the first accommodating chamber 2021 is relatively low, and the items are cooled and refrigerated. In addition, the internal structure of the box 202 is simple and easy to process, thereby improving the production efficiency of the box 202.

[0112] Further, refer to Figure 1 and Figure 2, the return air port 2023b is located above the air outlet 2023a, and the fan 203 is located at the return air port 2023b. With such a configuration, air can flow from the bottom of the box 202 to the top of the box 202, effectively ensuring that the air can pass through the items, thereby cooling or heating the items, and improving the cooling or heating effect of the box 202. In addition, under the action of the fan 203, it is effectively ensured that the air can enter the air duct 2023 from the return air port 2023b, thereby facilitating heat exchange of the air, making the temperature of the air discharged from the air outlet 2023a lower or higher, thereby allowing the refrigerator 200 to be used normally for a long time.

[0113] According to some embodiments of the utility model, the fan 203 is a centrifugal fan. Such a configuration is conducive to the air in the first accommodating chamber 2021 flowing to the return air port 2023b, thereby facilitating the operation of the refrigerator heat exchange module 201. The centrifugal fan 203 has the advantages of high efficiency, high temperature resistance, excellent performance, novel and compact structure, low vibration, light weight, convenient installation and maintenance, and long service life, thereby facilitating the installation of the fan 203 and improving the installation efficiency of the refrigerator 200. In addition, the fan 203 has low vibration, low noise, and stable operation, so that the fan 203 can operate stably for a long time.

[0114] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 , the refrigerator 200 further includes an energy storage box 204, which is disposed in the second accommodating cavity 2022, and the energy storage box 204 and the inner wall of the second accommodating cavity 2022 jointly define an air duct 2023, and the energy storage material and the indirect heat exchanger 2012 are both disposed in the energy storage box 204. Figure 1 and Figure 2 In the example, the energy storage box 204 is located on the side of the direct heat exchanger 2011 and the energy storage material heat exchanger 2013 away from the first accommodating chamber 2021, and the side of the energy storage box 204 facing the first accommodating chamber 2021 and the inner wall of the second accommodating chamber 2022 close to the first accommodating chamber 2021 jointly define an air duct 2023. In this way, the energy storage box 204 can accommodate the energy storage material piece and the indirect heat exchanger 2012, so that the energy storage material piece and the indirect heat exchanger 2012 can be installed together with the energy storage box 204, reducing the difficulty of installing the energy storage material piece and the indirect heat exchanger 2012, thereby improving the installation efficiency of the refrigerator 200. In addition, it is also easy to form the air duct 2023, which is conducive to further improving the installation efficiency of the refrigerator 200.

[0115] Optionally, refer to Figure 2 A pump 205 is provided between the energy storage material heat exchanger 2013 and the energy storage tank 204. Figure 2In the example, the pump 205 is located at the bottom of the energy storage box 204, one end of the pump 205 is connected to the inside of the energy storage box 204, the other end of the pump 205 passes through the side wall of the energy storage box 204 and is connected to the inlet 2061 of the energy storage material heat exchanger 2013, the outlet 2062 of the energy storage material heat exchanger 2013 is connected to the top of the energy storage box 204, and the above-mentioned one end of the pump 205 is located at the bottom of the energy storage box 204. After the pump 205 is turned on, the energy storage material pieces in the energy storage box 204 can be drawn to flow through the energy storage material heat exchanger 2013 and then exchange heat with the wind (i.e., flowing air) of the energy storage material heat exchanger 2013 passing through the air duct 2023. After the heat exchange, the energy storage material pieces flow out from the outlet 2062 of the energy storage material heat exchanger 2013 and flow into the energy storage box 204. With such an arrangement, by setting the pump 205, it is convenient to utilize the energy in the energy storage material to exchange heat with the air through the energy storage material heat exchanger 2013, so as to cool or heat the items in the box body 202. It is easy to operate and it is also convenient to control the amount of heat exchange of the refrigerator 200. According to the use of the refrigerator 200, by turning on and off the pump 205, it is decided whether to use the energy storage material heat exchanger 2013 for heat exchange, thereby improving the flexibility of the use of the refrigerator 200.

[0116] According to the thermal management system 100 of the second embodiment of the utility model, refer to Fig.12 , including an air conditioning module 1 and a refrigeration box module 2.

[0117] Specifically, the air-conditioning module 1 includes a compressor 11, an outdoor heat exchanger 13 and a first indoor heat exchanger 14 connected to form a refrigerant circuit, one end of the outdoor heat exchanger 13 is connected to the outlet of the compressor 11, and the first indoor heat exchanger 14 is connected between the other end of the outdoor heat exchanger 13 and the inlet of the compressor 11.

[0118] For example, in Fig.12 In the example, the inlet of the external heat exchanger 13 is connected to the outlet of the compressor 11, the inlet of the first internal heat exchanger 14 is connected to the outlet of the external heat exchanger 13, and the outlet of the first internal heat exchanger 14 can be connected to the inlet of the compressor 11.

[0119] When the air conditioning module 1 is in cooling mode, the compressor 11 , the outdoor heat exchanger 13 and the first indoor heat exchanger 14 are connected in series.

[0120] For example, in Fig.13In the example, the air conditioning module 1 is in the cooling mode. When the refrigerant flowing out of the outlet of the compressor 11 passes through the external heat exchanger 13, the external heat exchanger 13 acts as a condenser, and the refrigerant exchanges heat with the external environment, and the refrigerant releases heat. The first in-vehicle heat exchanger 14 acts as an evaporator, and the refrigerant absorbs heat from the high-temperature air in the vehicle. When the refrigerant flows through the first in-vehicle heat exchanger 14, the refrigerant exchanges heat with the air in the vehicle to cool the air in the vehicle, realizing the cooling mode of the air conditioning module 1. Therefore, when the temperature in the vehicle is high, the cooling mode of the air conditioning module 1 can be turned on to cool the vehicle, thereby improving the comfort of the users in the vehicle.

[0121] Combination Fig.12 The refrigerator module 2 is a refrigerator heat exchange module 201 of a refrigerator 200 according to the first embodiment of the utility model, and the refrigerator module 2 is connected in parallel with the first in-vehicle heat exchanger 14. Fig.12 In the example, the inlet of the refrigeration box module 2 is connected to the outlet of the outdoor heat exchanger 13, and the outlet of the refrigeration box module 2 is connected to the inlet of the compressor 11. The thermal management system 100 can be in the following modes: First, only the air-conditioning module 1 is in the cooling mode. Second, only the refrigeration box is in the cooling mode, at which time the compressor 11, the outdoor heat exchanger 13 and the refrigeration box module 2 are arranged in series with each other. Third, the air-conditioning module 1 is in the cooling mode, and the synchronous refrigeration box module 2 is in the cooling mode. At this time, the compressor 11, the outdoor heat exchanger 13 and the first indoor heat exchanger 14 are connected in series with each other to form a complete loop. At the same time, the compressor 11, the outdoor heat exchanger 13 and the refrigeration box module 2 are connected in series with each other to form a complete loop. The first indoor heat exchanger 14 and the refrigeration box module 2 are arranged in parallel with each other, that is, part of the refrigerant flowing out of the outdoor heat exchanger 13 flows to the inlet of the compressor 11 through the first indoor heat exchanger 14, and the other part flows to the inlet of the compressor 11 through the refrigeration box module 2 (such as Fig.17 As shown). With such a configuration, the refrigeration box module 2 can cool items, and the user can choose whether to cool the items according to actual usage, thereby increasing the usage modes of the thermal management system 100, improving the flexibility of the use of the thermal management system 100, and improving the convenience of the use of the thermal management system 100, thereby improving the user experience.

[0122] According to some embodiments of the present invention, referring to Fig.12 The air conditioning module 1 further includes a second in-vehicle heat exchanger 12, which is connected between the outlet of the compressor 11 and the above-mentioned one end of the external heat exchanger 13. Fig.12 In the example, the inlet of the second in-vehicle heat exchanger 12 and the outlet of the compressor 11 can be communicated, and the outlet of the second in-vehicle heat exchanger 12 and the inlet of the external heat exchanger 13 can be communicated.

[0123] The setting of the air conditioning module 1 includes the following modes: First, the air conditioning module 1 is in the cooling mode, the compressor 11, the second in-car heat exchanger 12, the external heat exchanger 13 and the first in-car heat exchanger 14 are arranged in series, wherein the second in-car heat exchanger 12 has no wind passing through it, and the second in-car heat exchanger 12 only serves as a passage. Second, the air conditioning module 1 is in the heating mode, the compressor 11, the second in-car heat exchanger 12 and the external heat exchanger 13 are arranged in series, wherein the second in-car heat exchanger 12 has wind passing through it.

[0124] For example, in Fig.16 In the example, when the air-conditioning module 1 is in the heating mode, when the refrigerant passes through the second in-car heat exchanger 12, there is wind passing through the second in-car heat exchanger 12, and the refrigerant exchanges heat with the low-temperature air in the car while passing through the second in-car heat exchanger 12. The refrigerant releases heat to the low-temperature air, and the air in the car is heated up, thus realizing the heating mode of the air-conditioning module 1. The refrigerant exchanges heat with the outside environment in the outdoor heat exchanger 13, and the refrigerant absorbs heat. When the temperature inside the car is low, the heating mode of the air-conditioning module 1 can be turned on to heat up the car, thereby improving the comfort of the users inside the car. In addition, the cooling mode or heating mode of the air-conditioning module 1 can be flexibly adjusted according to the temperature inside the car, thereby improving the applicability of the thermal management system 100.

[0125] According to some embodiments of the present invention, referring to Fig.12 The thermal management system 100 further includes a heating box module 3, which is a refrigerator heat exchange module 201 of the refrigerator 200 according to the first embodiment of the utility model, and the heating box module 3 is connected in parallel with the second in-vehicle heat exchanger 12. Fig.12 In the example, the inlet of the heating tank module 3 is communicated with the outlet of the compressor 11 , and the outlet of the heating tank module 3 is communicated with the inlet of the outdoor heat exchanger 13 .

[0126] The thermal management system 100 can be in the following modes: First, only the air-conditioning module 1 is in the heating mode. Second, only the heating box module 3 is in the heating mode, and the compressor 11, the heating box module 3 and the outdoor heat exchanger 13 are connected in series. Third, the air-conditioning module 1 is in the heating mode, and the heating box module 3 is in the heating mode. At this time, the compressor 11, the second indoor heat exchanger 12 and the outdoor heat exchanger 13 are connected in series to form a complete loop, and the compressor 11, the heating box module 3 and the outdoor heat exchanger 13 are connected in series to form a complete loop. The second indoor heat exchanger 12 and the heating box module 3 are connected in parallel, that is, part of the refrigerant flowing out from the outlet of the compressor 11 flows to the outdoor heat exchanger 13 through the second indoor heat exchanger 12, and the other part flows to the outdoor heat exchanger 13 through the heating box module 3 (such as Fig.16 Fourth, as shown in Fig.17As shown, the refrigeration box module 2 is in cooling mode, and the synchronous heating box module 3 is in heating mode. In this state, the compressor 11, the heating box module 3, the outdoor heat exchanger 13 and the refrigeration box module 2 are arranged in series.

[0127] With such a configuration, the heating box module 3 can heat the items. The thermal management system 100 has both the heating box module 3 and the refrigeration box module 2. The user can choose to cool or heat the items according to actual usage. That is, it has both the refrigeration function of the refrigeration box module 2 and the heating function of the heating box module 3. This further increases the usage modes of the thermal management system 100. The user can choose to use it according to actual usage, which improves the flexibility of the use of the thermal management system 100, and also improves the convenience of using the thermal management system 100, thereby improving the user experience.

[0128] In addition, the cooling mode of the air-conditioning module 1, the heating mode of the air-conditioning module 1, the cooling mode of the refrigeration box module 2 and the heating mode of the heating box module 3 are independent of each other through different circuit settings, and do not affect each other. They can simultaneously meet the functions of preparing hot drinks and refrigerating and preserving food, and can also realize the use of different temperature sections of the air-conditioning module 1, the refrigeration box module 2 and the heating box module 3, thereby improving the performance of the thermal management system 100 and facilitating meeting the needs of users.

[0129] In addition, compared with the conventional technology, the air conditioning module 1, the refrigeration box module 2 and the heating box module 3 are integrated into the same thermal management system 100. The refrigeration box module 2 and the heating box module 3 can utilize the compressor 11 and the vehicle-external heat exchanger 13 in the thermal management system 100 to dissipate the heat or cold in the vehicle through the vehicle-external heat exchanger 13, thereby reducing the number of components for dissipating waste heat in the refrigeration box module 2 and the heating box module 3, thereby increasing the effective volume of the refrigeration box module 2 and the heating box module 3 in the vehicle, and increasing the storage capacity of the refrigeration box module 2 and the heating box module 3. The waste heat generated by the refrigeration box module 2 and the heating box module 3 can also be discharged to the outside of the vehicle, avoiding the burden on the air conditioning module 1 when discharged into the vehicle, and avoiding the waste heat blowing onto the user, thereby improving the comfort of the user in the vehicle and the driving comfort. It should be noted that the heating mode of the air-conditioning module 1 and the heating mode of the heating box module 3 use a heat pump system for heating, thereby meeting the customer's needs for the temperature inside the car and heating of items (such as food or beverages) in cold weather.

[0130] According to some embodiments of the present invention, referring to Fig.12, the first refrigerant flow path of the refrigerating box module 2 is connected to the refrigerant circuit in an on-off manner. And / or, the first refrigerant flow path of the heating box module 3 is connected to the refrigerant circuit in an on-off manner. The configuration of the refrigerating box module 2 and the heating box module 3 includes the following situations: First, the first refrigerant flow path of the refrigerating box module 2 is connected to the refrigerant circuit in an on-off manner (for example, Fig.13 and Fig.15 The first refrigerant circuit of the refrigeration box module 2 is disconnected from the refrigerant circuit. Fig.17 The first refrigerant flow path of the refrigerating box module 2 is connected to the refrigerant circuit. Second, the first refrigerant flow path of the heating box module 3 is connected to the refrigerant circuit in an on-off manner (for example, Fig.14 and Fig.16 The first refrigerant circuit of the heating box module 3 is disconnected from the refrigerant circuit. Fig.18 The first refrigerant flow path of the heating box module 3 is connected to the refrigerant circuit. Third, the first refrigerant flow path of the refrigeration box module 2 is connected to the refrigerant circuit in a disconnectable manner, and the first refrigerant flow path of the heating box module 3 is connected to the refrigerant circuit in a disconnectable manner (for example, Fig.19 As shown, the first refrigerant circuit and the refrigerant circuit of the refrigeration box module 2 are disconnected, and at the same time, the first refrigerant circuit and the refrigerant circuit of the heating box module 3 are disconnected).

[0131] For example, when the first refrigerant flow path of the refrigerating box module 2 is connected to the refrigerant circuit, the refrigerant of the air conditioning module 1 can flow to the first refrigerant flow path to achieve heat exchange with the direct heat exchanger 21 and the indirect heat exchanger 22 of the refrigerating box module. With such a configuration, the first refrigerant flow path of the refrigerating box module 2 can be connected or disconnected with the refrigerant circuit according to the needs of the occupants, so as to connect or disconnect the first refrigerant flow path of the heating box module 3 with the refrigerant circuit, so that the thermal management system 100 can be in a variety of different modes and can be switched between a variety of modes, thereby improving the flexibility of the use of the thermal management system 100 and the adaptability of the use of the thermal management system 100, which is conducive to better meeting the needs of the occupants.

[0132] According to some embodiments of the present invention, referring to Fig.12 , the indirect heat exchanger 22 of the refrigeration box module 2 is connected between the inlet of the compressor 11 and the direct heat exchanger 21 of the refrigeration box module 2. For example, Fig.12 In the example, when the refrigerant passes through the refrigeration box module 2, it first passes through the direct heat exchanger 21 of the refrigeration box module 2, and then passes through the indirect heat exchanger 22 of the refrigeration box module 2. The inlet of the direct heat exchanger 21 of the refrigeration box module 2 is connected to the outlet of the external heat exchanger 13, the outlet of the direct heat exchanger 21 of the refrigeration box module 2 is connected to the inlet of the indirect heat exchanger 22 of the refrigeration box module 2, and the outlet of the indirect heat exchanger 22 of the refrigeration box module 2 is connected to the inlet of the compressor 11.

[0133] When the refrigerator 200 is cooling, the refrigerant can first pass through the direct heat exchanger 21 of the refrigeration box module 2, and then pass through the indirect heat exchanger 22 of the refrigeration box module 2. The refrigerant uses part of the cold energy to cool the items through the direct heat exchanger 21 of the refrigeration box module 2, and stores the other part of the cold energy in the cold storage material through the indirect heat exchanger 22 of the refrigeration box module 2.

[0134] The refrigeration box module 2 is connected in parallel with the first in-vehicle heat exchanger 14, and the evaporation pressures of the two are the same. When the refrigeration box module 2 and the air conditioning module 1 are refrigerating at the same time, the target evaporation temperature in the vehicle is about 0°C (corresponding to an evaporation pressure of 300kPa), and the target evaporation temperature of the refrigeration box in the vehicle (when the thermal management system 100 is used in a vehicle, the refrigeration box module 2 is used to cool the inside of the refrigeration box in the vehicle) is generally about -10°C (corresponding to an evaporation pressure of 200kPa). The evaporation temperature and evaporation pressure are coupled, and the lower the evaporation temperature, the lower the evaporation pressure. According to the refrigeration principle, the evaporation temperature of the refrigerant, such as the refrigerant, flowing through the refrigeration box module 2 is the same as the evaporation temperature of the refrigerant flowing through the first in-vehicle heat exchanger 14. It should be noted that when the refrigerator 200 is refrigerating, the refrigerator heat exchange module 201 may be the refrigerating box module 2, the direct heat exchanger 2011 of the refrigerator heat exchange module 201 may be the direct heat exchanger 21 of the refrigerating box module 2, the indirect heat exchanger 2012 of the refrigerator heat exchange module 201 may be the indirect heat exchanger 22 of the refrigerating box module 2, and the energy storage material of the refrigerator heat exchange module 201 may be the cold storage material of the refrigerating box module 2. In other words, the refrigerating box module 2 in the thermal management system 100 is the refrigerator heat exchange module 201 of the refrigerator 200, and different names and numbers are used for the convenience of distinction, so as to facilitate the understanding of the refrigerating box module 2 and the heating box module 3 of the thermal management system 100.

[0135] Combination Fig.37 The working states of the air conditioning module 1 and the refrigeration box module 2 may include the following situations:

[0136] First, when the air-conditioning module 1 is not working, for example, when the vehicle is parked, the direct heat exchanger 21 of the refrigeration box module 2 is not turned on to cool the load in the refrigeration box body 23, but the refrigerant flows through the indirect heat exchanger 22 of the refrigeration box module 2. At this time, the evaporation pressure is matched to the working pressure of the refrigeration box (about 200 kPa, evaporation temperature -10°C), that is, the indirect heat exchanger 22 of the refrigeration box module 2 is turned on to cool the cold storage material, so that the temperature of the cold storage material reaches the refrigeration temperature requirement of the refrigerator.

[0137] Second, when the passenger enters the passenger compartment and turns on the cooling mode of the air conditioning module 1, the thermal management system 100 only turns on the cooling flow path of the air conditioning module 1, that is, the refrigerant flows through the first in-vehicle heat exchanger 14 to cool the interior of the vehicle, and the refrigerant does not flow through the refrigeration box module 2. In this process, the evaporation pressure can be matched to the working pressure required by the air conditioning module 1 (about 300 kPa, evaporation temperature 0°C), and when the refrigeration box has a refrigeration demand, the cold storage material cools the interior of the refrigeration box, that is, the cold storage material cools.

[0138] Third, when the refrigeration box module 2 receives a work request and the air conditioning module 1 receives a work request for the cooling mode, the thermal management system 100 can only turn on the cooling mode of the air conditioning module 1, and the cooling circuit of the refrigeration box module 2 is not turned on. At this time, the cold storage material can be used to cool down the items. After the cold storage materials of the air conditioning module 1 and the refrigeration box module 2 have been working for a long time, the temperature increase of the cold storage material (for example, from -10°C to about 0°C) is not enough to play a cooling role. The cooling circuit of the refrigeration box module 2 is turned on, and the direct heat exchanger 21 of the refrigeration box module 2 is used for heat exchange to maintain the refrigeration temperature of the refrigeration box module 2 (for example, 0~10°C).

[0139] Fourth, when the refrigeration box module 2 receives a work request alone, that is, when only the refrigeration box module 2 is in the refrigeration mode, the evaporation pressure of the refrigerant matches the working pressure of the refrigeration box (about 200 kPa, evaporation temperature -10°C), and the refrigerant exchanges heat with the air flowing to the direct heat exchanger 21 of the refrigeration box module 2 when flowing through the direct heat exchanger 21 of the refrigeration box module 2, and the direct heat exchanger 21 of the refrigeration box module 2 cools. When the refrigerant flows through the indirect heat exchanger 22 of the refrigeration box module 2, a part of the cold energy is stored in the cold storage material through the indirect heat exchanger 22 of the refrigeration box module 2.

[0140] With such a configuration, when the refrigerator module 2 is cooling, it is necessary to simultaneously exchange heat with the food and beverage items and the cold storage material in the refrigerator module 2, that is, the coldness of the refrigerant can be stored in the cold storage material in addition to being used for heat exchange in the direct heat exchanger 21 of the refrigerator module 2, thereby increasing the coldness demand of the refrigerator module 2, effectively increasing the heat exchange amount, and reducing the difference in heat exchange amount between the refrigerator module 2 and the air conditioning module 1, thereby solving the problem of mismatch in evaporation pressure and coldness between functions of different temperature control when the refrigerator module 2 and the air conditioning module 1 are cooling at the same time. Moreover, the distribution of the refrigerant is more reasonable, effectively ensuring the cooling speed of the refrigerator module 2, meeting the needs of users, and effectively ensuring the cooling capacity of the air conditioning module 1, making the thermal management system 100 more matched as a whole, and each component of the thermal management system 100 (for example, the evaporator, the compressor 11, the condenser and the pipeline, etc.) is relatively matched with each other, thereby ensuring the normal operation of the thermal management system 100.

[0141] According to other embodiments of the present invention, Fig.12 , the indirect heat exchanger 32 of the heating tank module 3 is connected between the outlet of the compressor 11 and the direct heat exchanger 31 of the heating tank module 3. Fig.12 In the example, when the refrigerant passes through the heating box module 3, it first passes through the indirect heat exchanger 32 of the heating box module 3, and then passes through the direct heat exchanger 31 of the heating box module 3. The inlet of the indirect heat exchanger 32 of the heating box module 3 is connected to the outlet of the compressor 11, the outlet of the indirect heat exchanger 32 of the heating box module 3 is connected to the inlet of the direct heat exchanger 31 of the heating box module 3, and the outlet of the direct heat exchanger 31 of the heating box module 3 is connected to the inlet of the outdoor heat exchanger 13.

[0142] When the refrigerator 200 is heating, the refrigerant may first pass through the indirect heat exchanger 32 of the heating box module 3, and then pass through the direct heat exchanger 31 of the heating box module 3. The refrigerant stores part of the heat in the energy storage material through the indirect heat exchanger 32 of the heating box module 3, and heats the items through the direct heat exchanger 31 of the heating box module 3. It should be noted that when the refrigerator 200 is heating, the refrigerator heat exchange module 201 may be the heating box module 3, the direct heat exchanger 2011 of the refrigerator heat exchange module 201 may be the direct heat exchanger 31 of the heating box module 3, the indirect heat exchanger 2012 of the refrigerator heat exchange module 201 may be the indirect heat exchanger 32 of the heating box module 3, and the energy storage material of the refrigerator heat exchange module 201 may be the heat storage material of the heating box module 3. That is to say, the heating box module 3 in the thermal management system 100 is the refrigerator heat exchange module 201 of the refrigerator 200. Different names and numbers are used to facilitate the distinction, so as to facilitate the understanding of the refrigeration box module 2 and the heating box module 3 of the thermal management system 100.

[0143] Combination Fig.38 The working states of the air conditioning module 1 and the heating box module 3 may include the following situations:

[0144] First, when the air-conditioning module 1 is not working, for example, when the vehicle is parked, the direct heat exchanger 31 of the heating box module 3 is not turned on to heat up the load in the heating box body 33, but the refrigerant flows through the indirect heat exchanger 32 of the heating box module 3. At this time, the inlet temperature of the indirect heat exchanger 32 of the heating box module 3 is matched to the working temperature of the heating box (about 60°C), that is, the indirect heat exchanger 32 of the heating box module 3 is turned on to heat up the heat storage material component, so that the temperature of the heat storage material component reaches the heating temperature requirement of the refrigerator.

[0145] Second, when the passenger enters the passenger compartment and turns on the heating mode of the air conditioning module 1, the thermal management system 100 only turns on the heating flow path of the air conditioning module 1, that is, the refrigerant flows through the second in-vehicle heat exchanger 12 to heat the interior of the vehicle, and the refrigerant does not flow through the heating box module 3. In this process, the evaporation pressure can be matched to the working pressure required by the air conditioning module 1, and when the heating box has a heating demand, the heat of the heat storage material component heats the interior of the box, that is, the heat storage material component heats.

[0146] Third, when the heating box module 3 receives a work request and the air conditioning module 1 receives a work request for the heating mode, the thermal management system 100 can only turn on the heating mode of the air conditioning module 1, and the heating circuit of the heating box module 3 is not turned on. At this time, the heat of the heat storage material can be used to heat the items. After the heat storage material of the air conditioning module 1 and the heating box module 3 have been working for a long period of time, the temperature of the heat storage material has dropped (for example, from 60°C to about 45°C) and is not enough to play a heating and cooling role. The heating circuit of the heating box module 3 is turned on, and the heat distribution of the thermal management system 100 gives priority to ensuring the heating of the air conditioning module 1, and uses the residual heat and heat exchange through the direct heat exchanger 31 of the heating box module 3 to maintain the heating temperature of the heating box module 2 (for example, 45°C).

[0147] Fourth, when the heating box module 3 receives a work request alone, that is, when only the heating box module 3 is in the heating mode, the temperature of the refrigerant at the inlet of the direct heat exchanger 31 of the heating box module 3 is matched to the working temperature of the heating box (about 60°C), and the refrigerant exchanges heat with the air flowing to the direct heat exchanger 31 of the heating box module 3 when flowing through the direct heat exchanger 31 of the heating box module 3, and the direct heat exchanger 31 of the heating box module 3 heats. When the refrigerant flows through the indirect heat exchanger 32 of the heating box module 3, part of the heat is stored in the heat storage material through the indirect heat exchanger 22 of the heating box module 3.

[0148] With such arrangement, when the heating box module 3 is heating, heating can be generated through the heat storage material and the direct heat exchanger 31 of the heating box module 3 to meet the working requirements of the heating box module 3, and the difference in heat exchange between the heating box module 3 and the air-conditioning module 1 is reduced, thereby solving the problem of heat mismatch between functions of different temperature control when the heating box module 3 and the air-conditioning module 1 are heating. The distribution of refrigerant is more reasonable, which effectively guarantees the heating speed of the heating box module 3 and meets the needs of users, and also effectively guarantees the heating capacity of the air-conditioning module 1, making the thermal management system 100 more matched as a whole, and each component of the thermal management system 100 (for example, the evaporator, compressor 11, condenser and pipeline, etc.) is relatively matched with each other, thereby ensuring the normal operation of the thermal management system 100.

[0149] According to some further embodiments of the present invention, referring to Fig.12The indirect heat exchanger 22 of the refrigerating box module 2 is connected between the inlet of the compressor 11 and the direct heat exchanger 21 of the refrigerating box module 2. At the same time, the indirect heat exchanger 32 of the heating box module 3 is connected between the outlet of the compressor 11 and the direct heat exchanger 31 of the heating box module 3.

[0150] With such a configuration, the temperature of the refrigerant flowing out of the compressor 11 is relatively high, and the refrigerant passes through the indirect heat exchanger 32 of the heating box module 3 and the direct heat exchanger 31 of the heating box module 3 in turn, so that part of the heat is stored in the heat storage material through the indirect heat exchanger 32 of the heating box module 3, and the other part of the heat is heated by the direct heat exchanger 31 of the heating box module 3, thereby reducing the loss of heat in the refrigerant and improving the utilization rate of the heat in the refrigerant. In addition, the refrigerant passes through the direct heat exchanger 21 of the refrigeration box module 2 and the indirect heat exchanger 22 of the refrigeration box module 2 in turn, and the refrigerant cools the articles with part of the cold through the direct heat exchanger 21 of the refrigeration box module 2, and stores the other part of the cold in the cold storage material through the indirect heat exchanger 22 of the refrigeration box module 2, thereby reducing the loss of cold in the refrigerant and improving the utilization rate of cold in the refrigerant. In addition, the heat exchange capacity of the refrigeration box module 2 and the heating box module 3 is effectively increased, and the difference in heat exchange capacity between the heating box module 3 and the refrigeration box module 2 and the air-conditioning module 1 is reduced, thereby solving the problem of heat mismatch between the heating box module 3, the refrigeration box module 2 and the air-conditioning module 1 with different temperature control functions, and making the distribution of refrigerant more reasonable, thereby enabling the thermal management system 100 to be used normally.

[0151] According to some embodiments of the present invention, referring to Fig.12 , one end of the outdoor heat exchanger 13 can be selectively connected to at least one of the second indoor heat exchanger 12 and the heating box module 3, and the other end of the outdoor heat exchanger 13 can be selectively connected to at least one of the first indoor heat exchanger 14, the refrigeration box module 2 and the inlet of the compressor 11. For example, when the inlet end of the outdoor heat exchanger 13 (i.e., the above-mentioned one end of the outdoor heat exchanger 13) is connected to the outlet of the second indoor heat exchanger 12, the air conditioning module 1 in the thermal management system 100 can be in the heating mode (such as the second indoor heat exchanger 12 has wind passing through), or other modes (such as the second indoor heat exchanger 12 has no wind passing through). When the inlet end of the outdoor heat exchanger 13 is connected to the outlet of the heating box module 3, the heating box module 3 in the thermal management system 100 can be in the heating mode. When the outlet end of the outdoor heat exchanger 13 (ie, the other end of the outdoor heat exchanger 13 ) is connected to the inlet end of the first indoor heat exchanger 14 , the air conditioning module 1 in the thermal management system 100 may be in cooling mode.

[0152] When the outlet end of the outdoor heat exchanger 13 is connected to the inlet end of the refrigeration box module 2, the refrigeration box module 2 in the thermal management system 100 can be in cooling mode. When the outlet end of the outdoor heat exchanger 13 is connected to the inlet end of the compressor 11, in the thermal management system 100, only the air conditioning module 1 is in heating mode or both the air conditioning module 1 and the heating box module 3 can be in heating mode. With such a configuration, by controlling the inlet and outlet ends of the outdoor heat exchanger 13 to be connected to other components in the thermal management system 100, the working mode of the thermal management system 100 can be switched, and the thermal management system 100 can be in a single mode or multiple modes at the same time, which effectively improves the flexibility of using multiple modes of the thermal management system 100 and also improves the adaptability of the use of the thermal management system 100.

[0153] According to some embodiments of the present invention, referring to Fig.12 The thermal management system 100 further includes a first throttle valve 61 and a second throttle valve 62. The first throttle valve 61 is connected between the other end of the external heat exchanger 13 and the refrigeration box module 2. The second throttle valve 62 is connected between the refrigeration box module 2 and the inlet of the compressor 11. For example, Fig.12 In the example of , the first throttle valve 61 is located between the outlet of the external heat exchanger 13 and the inlet of the refrigeration box module 2, and the second throttle valve 62 is located between the outlet of the refrigeration box module 2 and the inlet of the compressor 11. For example, the first throttle valve 61 may be an electronic expansion valve, and the second throttle valve 62 may be a large-caliber electronic expansion valve. But it is not limited thereto.

[0154] It should be noted that in Fig.13 In the example, the dotted line is the flow route of the refrigerant, and the direction indicated by the arrow is the flow direction of the refrigerant.

[0155] For example, refer to Fig.13 When the items need to be cooled, that is, when the refrigerator is in the cooling mode, the first throttle valve 61 and the second throttle valve 62 are opened respectively, and the refrigerant can be controlled to pass through the compressor 11, the second in-vehicle heat exchanger 12, the outside heat exchanger 13, the first throttle valve 61, the refrigerator module 2 and the second throttle valve 62 in sequence, and then flow back to the compressor 11. The first throttle valve 61 is opened to play a throttling role.

[0156] The flow of refrigerant in the refrigeration box module 2 is as follows: first, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas, and then the refrigerant enters the second in-vehicle heat exchanger 12. At this time, there is no wind passing through the second in-vehicle heat exchanger 12, and it only flows as a flow channel. The refrigerant discharged from the outlet of the second in-vehicle heat exchanger 12 is still a high-temperature and high-pressure gas. Then the refrigerant passes through the outdoor heat exchanger 13, and the refrigerant exchanges heat with the outdoor environment through the outdoor heat exchanger 13. The outdoor heat exchanger 13 acts as a condenser, and the refrigerant releases heat. The refrigerant discharged from the outlet of the outdoor heat exchanger 13 is a medium-temperature and high-pressure fluid (it should be noted that the fluid can be a liquid or a gas, and the state of the fluid is determined by the temperature of the outdoor environment). Subsequently, the refrigerant passes through the first throttle valve 61, which throttles and cools the refrigerant, and turns it into low-temperature and low-pressure wet steam or supercooled liquid. The refrigerant continues to flow into the refrigeration box module 2. At this time, the first direct heat exchanger 21 in the refrigeration box module 2 acts as an evaporator, thereby reducing the temperature in the refrigeration box body 23, absorbing the heat of the articles, and cooling the articles, so that the refrigeration box module 2 can refrigerate the articles. The refrigerant discharged from the outlet of the refrigeration box module 2 is a low-temperature and low-pressure fluid. The refrigerant continues to flow through the second throttle valve 62 and flows back to the compressor 11 for circulation.

[0157] It should be noted that when the refrigeration box module 2 works alone, the pressure is about 200 kPa and the evaporation temperature is -10°C. When the air conditioning module 1 is not refrigerating, the refrigerant flowing through the first indirect heat exchanger 22 can reduce the temperature of the cold storage material to the target temperature of -10°C. When the refrigeration box module 2 is not working, the first fan 2333 is shut down, and the refrigerant is only used to cool the energy storage material. When the refrigeration box module 2 is in a refrigeration state, the first direct heat exchanger 21 and the cold storage material can both be used to cool the inside of the refrigeration box.

[0158] For example, after the refrigeration box module 2 receives a work request, the refrigerant refrigeration of the refrigeration box module 2 in the thermal management system 100 is turned on, that is, the first throttle valve 61 and the second throttle valve 62 are opened, and the evaporation pressure is matched to the working pressure of the refrigeration box module 2 (for example, about 200 kPa), the first fan 2333 in the refrigeration box body 23 is turned on, and the first direct heat exchanger 21 starts cooling the refrigeration box body 23, and then a part of the cold energy is stored in the cold storage material through the first indirect heat exchanger 22.

[0159] Therefore, the first throttle valve 61 can connect and disconnect the connection between the external heat exchanger 13 and the refrigeration box module 2, and throttle the refrigerant, and the second throttle valve 62 can connect and disconnect the connection between the refrigeration box module 2 and the compressor 11, so that the first throttle valve 61 and the second throttle valve 62 can open or close the refrigerant circuit in the refrigeration box module 2, which is easy to control the working mode of the refrigeration box module 2, thereby improving the performance of the thermal management system 100.

[0160] According to some embodiments of the present invention, referring to Fig.14 The thermal management system 100 further includes a third throttle valve 63 and a fourth throttle valve 64. The third throttle valve 63 is connected between one end of the heating tank module 3 and one end of the vehicle exterior heat exchanger 13. The fourth throttle valve 64 is connected between the other end of the heating tank module 3 and the outlet of the compressor 11. For example, Fig.14 In the example, the inlet end of the third throttle valve 63 is connected to the outlet end of the heating box module 3 (i.e., one end of the above-mentioned heating box module 3), the outlet end of the third throttle valve 63 is connected to the inlet end of the vehicle exterior heat exchanger 13 (i.e., one end of the above-mentioned vehicle exterior heat exchanger 13), the inlet end of the fourth throttle valve 64 is connected to the outlet end of the compressor 11, and the outlet end of the fourth throttle valve 64 is connected to the inlet end of the heating module (i.e., the other end of the heating box module 3). For example, the third throttle valve 63 may be an electronic expansion valve, and the fourth throttle valve 64 may be a large-caliber electronic expansion valve. But it is not limited thereto.

[0161] It should be noted that in Fig.14 In the example, the dotted line is the flow route of the refrigerant in the heating box module 3, and the direction indicated by the arrow is the flow direction of the refrigerant.

[0162] For example, refer to Fig.14 When the article needs to be heated, that is, when the heating box module 3 is in the heating mode, the third throttle valve 63 and the fourth throttle valve 64 are opened respectively, and the refrigerant can be controlled to pass through the compressor 11, the fourth throttle valve 64, the heating box module 3, the third throttle valve 63 and the external heat exchanger 13 in sequence, and then flow back to the compressor 11. The third throttle valve 63 plays a throttling role.

[0163] The refrigerant in the heating box module 3 flows as follows: First, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas. The refrigerant continues to flow through the fourth throttle valve 64 and flows into the heating box module 3. At this time, the heating box module 3 acts as a condenser, and the refrigerant dissipates heat, thereby heating the items in the heating box body 33. The refrigerant discharged from the outlet of the heating box module 3 is a medium-temperature and high-pressure fluid. Then, the refrigerant passes through the third throttle valve 63, and the third throttle valve 63 throttles and cools the refrigerant, turning it into a low-temperature and low-pressure wet steam or a supercooled liquid. Next, the refrigerant passes through the outdoor heat exchanger 13, and at this time, the outdoor heat exchanger 13 is an evaporator. The refrigerant is heated by the outdoor environment through the outdoor heat exchanger 13, completing the process of absorbing heat from the outdoor environment. The refrigerant discharged from the outlet of the outdoor heat exchanger 13 is a low-temperature and low-pressure fluid. Subsequently, the refrigerant continues to flow into the compressor 11 and circulates.

[0164] It should be noted that when the air conditioning module 1 is not working, the heating box module 3 can work alone to raise the temperature of the heat storage material to the target temperature of 60° C. When the heating box module 3 is not working, the first fan 2333 is stopped, and the refrigerant only exchanges heat with the heat storage material at the second indirect heat exchanger 32 .

[0165] After the heating box module 3 receives the work request, the refrigerant reflux of the heating box module 3 in the thermal management system 100 is turned on, that is, the third throttle valve 63 and the fourth throttle valve 64 are opened, and the inlet temperature of the refrigerant flow path is matched to the working temperature of the heating box module 3 (for example, about 60°C), the second fan 3333 in the heating box body 33 is turned on, and the second direct heat exchanger 31 starts heating the heating box body 33, and then a part of the heat is stored in the heat storage material through the second indirect heat exchanger 32.

[0166] Thus, the third throttle valve 63 can connect and disconnect the connection between the outdoor heat exchanger 13 and the heating box module 3, and throttle the refrigerant, and the fourth throttle valve 64 can connect and disconnect the connection between the heating box module 3 and the compressor 11, so that the third throttle valve 63 and the fourth throttle valve 64 can open or close the refrigerant circuit in the heating box module 3, which is easy to control whether the heating box module 3 is in the heating mode, thereby improving the performance of the thermal management system 100.

[0167] According to some embodiments of the present invention, referring to Fig.15 The thermal management system 100 further includes a fifth throttle valve 65 and a first on-off valve 71, the fifth throttle valve 65 is connected between the other end of the external heat exchanger 13 and the first internal heat exchanger 14, and the first on-off valve 71 is connected between the other end of the external heat exchanger 13 and the inlet of the compressor 11.

[0168] For example, in Fig.15 In the example, the inlet end of the fifth throttle valve 65 is connected to the outlet end of the external heat exchanger 13 (i.e., the other end of the external heat exchanger 13), and the outlet end of the fifth throttle valve 65 is connected to the inlet end of the first internal heat exchanger 14. The inlet end of the first on-off valve 71 is connected to the outlet end of the external heat exchanger 13, and the outlet end of the first on-off valve 71 is connected to the inlet end of the compressor 11. For example, the fifth throttle valve 65 may be an electronic expansion valve, and the first on-off valve 71 may be a solenoid valve. But it is not limited thereto.

[0169] It should be noted that in Fig.15 and Fig.16 In the example, the dotted line is the flow route of the refrigerant, and the direction indicated by the arrow is the flow direction of the refrigerant.

[0170] For example, refer to Fig.15When the vehicle needs to be cooled, the air conditioning module 1 is in cooling mode, the fifth throttle valve 65 is opened, and the first on-off valve 71 is closed, so that the refrigerant can be controlled to pass through the compressor 11, the second in-vehicle heat exchanger 12, the outside heat exchanger 13, the fifth throttle valve 65 and the first in-vehicle heat exchanger 14 in sequence, and then flow back to the compressor 11. The fifth throttle valve 65 is opened to play a throttling role.

[0171] The refrigerant reflux during cooling in the air-conditioning module 1 is as follows: First, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas. Then, the refrigerant enters the second in-vehicle heat exchanger 12. At this time, there is no wind passing through the second in-vehicle heat exchanger 12, and it only flows through as a flow channel. The refrigerant discharged from the outlet of the second in-vehicle heat exchanger 12 is still a high-temperature and high-pressure gas. Next, the refrigerant passes through the outdoor heat exchanger 13. The refrigerant exchanges heat with the outdoor environment through the outdoor heat exchanger 13, and the refrigerant releases heat. The outdoor heat exchanger 13 acts as a condenser, and the refrigerant discharged from the outlet of the outdoor heat exchanger 13 is a medium-temperature and high-pressure fluid (it should be noted that the fluid can be a liquid or a gas, which is determined by the temperature of the outdoor environment). Subsequently, the refrigerant passes through the fifth throttle valve 65, which throttles and cools the refrigerant, turning it into low-temperature, low-pressure wet steam or supercooled liquid. The refrigerant continues to flow into the first in-vehicle heat exchanger 14. At this time, the high-temperature air in the vehicle passes through the first in-vehicle heat exchanger 14. The first in-vehicle heat exchanger 14 acts as an evaporator, and the refrigerant absorbs heat. The high-temperature air is cooled to low-temperature air for refrigeration in the vehicle. The refrigerant discharged from the outlet of the first in-vehicle heat exchanger 14 is a low-temperature, low-pressure fluid. The refrigerant continues to flow into the compressor 11, circulates, and is used. For example, when the refrigeration box module 2 works alone, the pressure is about 300 kPa, and the evaporation temperature is 0°C.

[0172] After only the air-conditioning module 1 receives the cooling work request, the refrigerant flow path of the air-conditioning module 1 in the thermal management system 100 is opened, that is, the fifth throttle valve 65 is opened, the first on-off valve 71 is closed, and the evaporating pressure is matched to the cooling working pressure (for example, about 300 kPa) and evaporating temperature (for example, 0°C) of the air-conditioning module 1. At this time, the refrigerant flow path of the refrigeration box module 2 is closed, and the first fan 2333 in the refrigeration box is shut down.

[0173] With such arrangement, through the cooperation of the fifth throttle valve 65 and the first on-off valve 71, the refrigerant flowing out of the external heat exchanger 13 can be controlled to pass through the second external heat exchanger 13, thereby realizing cooling of the interior of the vehicle by the air-conditioning module 1. When used in summer, it improves the user's comfort and meets the user's needs.

[0174] According to some embodiments of the present invention, referring to Fig.16The thermal management system 100 further includes a sixth throttle valve 66 and a second on-off valve 72, wherein the sixth throttle valve 66 is connected between the second in-vehicle heat exchanger 12 and one end of the external heat exchanger 13. The second on-off valve 72 is connected in parallel with the sixth throttle valve 66, and the external heat exchanger 13 can selectively communicate with at least one of the sixth throttle valve 66, the second on-off valve 72 and the heating box module 3.

[0175] For example, in Fig.16 In the example, the inlet end of the sixth throttle valve 66 is connected to the outlet end of the second in-vehicle heat exchanger 12, the outlet end of the sixth throttle valve 66 is connected to the inlet end of the external heat exchanger 13 (i.e., one end of the external heat exchanger 13), the inlet end of the second on-off valve 72 is connected to the outlet end of the second in-vehicle heat exchanger 12, and the outlet end of the second on-off valve 72 is connected to the inlet end of the external heat exchanger 13. For example, the sixth throttle valve 66 may be an electronic expansion valve, and the second on-off valve 72 may be a solenoid valve. But it is not limited thereto.

[0176] It should be noted that in Fig.16 In the example of , the dotted line is the flow route of the refrigerant, and the direction indicated by the arrow is the flow direction of the refrigerant.

[0177] For example, refer to Fig.16 When the vehicle needs to be heated, the air conditioning module 1 is in the heating mode, the sixth throttle valve 66 is opened, the second on-off valve 72 is closed, and the first on-off valve 71 is opened, so that the refrigerant can be controlled to pass through the compressor 11, the second in-vehicle heat exchanger 12, the sixth throttle valve 66 and the external heat exchanger 13 in sequence, and then flow back to the compressor 11 through the first on-off valve 71. The sixth throttle valve 66 is opened to play a throttling role.

[0178] The refrigerant reflux during heating in the air conditioning module 1 is as follows: First, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas. Then, the refrigerant enters the second in-vehicle heat exchanger 12. At this time, there is wind passing through the second in-vehicle heat exchanger 12, and the refrigerant dissipates heat. The low-temperature air in the car is heated to high-temperature air through the second in-vehicle heat exchanger 12 and supplied to the car for heating. The refrigerant discharged from the outlet of the second in-vehicle heat exchanger 12 is a medium-temperature and high-pressure fluid. Next, the refrigerant passes through the sixth throttle valve 66, and the sixth throttle valve 66 throttles and cools down, becoming low-temperature and low-pressure wet steam or supercooled liquid. Subsequently, the refrigerant passes through the outdoor heat exchanger 13, the outdoor heat exchanger 13 is an evaporator, and the second in-vehicle heat exchanger 12 is a condenser. The refrigerant is heated by the outdoor environment, and heat absorption from the outdoor environment is completed. The refrigerant discharged from the outlet of the outdoor heat exchanger 13 is a low-temperature and low-pressure fluid. Subsequently, the refrigerant continues to flow into the compressor 11 for circulation.

[0179] It should be noted that when the air conditioning module 1 is not working, the heating box module 3 can work alone, that is, the refrigerant flows through the heating box module 3 and exchanges heat with the second indirect heat exchanger 32 to increase the temperature of the heat storage material to the target temperature of 60°C. During this process, the first fan 2333 is shut down.

[0180] After only the air-conditioning module 1 receives the heating work request, the refrigerant flow path of the air-conditioning module 1 in the thermal management system 100 is opened, that is, the sixth throttle valve 66 is opened, and the second on-off valve 72 is closed. At this time, the refrigerant flow path of the heating box module 3 is closed, and the second fan 3333 in the heating box is shut down.

[0181] With such arrangement, through the cooperation of the sixth throttle valve 66 and the second on-off valve 72, it is possible to control whether the heating mode of the air-conditioning module 1 is turned on, thereby enabling the air-conditioning module 1 to heat the interior of the vehicle. When used in winter, this improves the user's comfort and meets the user's needs.

[0182] It should be noted that the first throttle valve 61, the second throttle valve 62, the third throttle valve 63, the fourth throttle valve 64, the fifth throttle valve 65, the sixth throttle valve 66 and the first on-off valve 71 and the second on-off valve 72 cooperate with each other, and the thermal management system 100 can also realize the following modes: First, the air conditioning module 1 is in the cooling mode, and the synchronous refrigeration box module 2 is in the cooling mode (such as Fig.17 Second, the air conditioning module 1 is in the heating mode, and the synchronous heating box module 3 is in the heating mode (as shown). Fig.18 Third, the refrigeration box module 2 is in the cooling mode, and the synchronous heating box module 3 is in the heating mode (as shown). Fig.19 Fourth, the air conditioning module 1 dehumidification mode (as shown) Fig. 20 Fifth, the air conditioning module 1 defog mode (as shown) Fig.21 ). Fig.17 , Fig.18 , Fig.19 , Fig. 20 and Fig.21 In the example, the dotted line is the flow route of the refrigerant, and the direction indicated by the arrow is the flow direction of the refrigerant.

[0183] For example, refer to Fig.18When the vehicle needs to be cooled and the items also need to be cooled, the air conditioning module 1 is in the cooling mode, and the synchronous refrigeration box module 2 is in the cooling mode. The second on-off valve 72, the first throttle valve 61, the second throttle valve 62 and the fifth throttle valve 65 are opened, and the sixth throttle valve 66, the fourth throttle valve 64, the third throttle valve 63 and the first on-off valve 71 are closed, so that the refrigerant can be controlled to pass through the compressor 11, the second in-vehicle heat exchanger 12, the second on-off valve 72 and the outside heat exchanger 13 in sequence, and then the refrigerant branches. The first branch is: the refrigerant passes through the first throttle valve 61, the refrigeration box module 2 and the second throttle valve 62 in sequence, and flows back to the compressor 11. The second branch is: the refrigerant passes through the first in-vehicle heat exchanger 14 in sequence and flows back to the compressor 11. The first throttle valve 61 and the fifth throttle valve 65 are opened to play a throttling role.

[0184] When the air conditioning module 1 is in cooling mode and the synchronous refrigeration box module 2 is cooling, the refrigerant refluxes as follows: First, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas. Then, the refrigerant enters the second in-vehicle heat exchanger 12. At this time, there is no wind passing through the second in-vehicle heat exchanger 12, and the second in-vehicle heat exchanger 12 only flows through as a flow channel. The refrigerant discharged from the outlet of the second in-vehicle heat exchanger 12 is still a high-temperature and high-pressure gas. The refrigerant continues to flow, and the refrigerant passes through the second on-off valve 72. Subsequently, the refrigerant passes through the outdoor heat exchanger 13, and the refrigerant exchanges heat with the outdoor environment through the outdoor heat exchanger 13, and the refrigerant releases heat. The refrigerant discharged from the outlet of the outdoor heat exchanger 13 is a medium-temperature and high-pressure fluid (it should be noted that the fluid can be a liquid or a gas, which is determined by the temperature of the outdoor environment).

[0185] After passing through the off-board heat exchanger 13, the refrigerant is divided into two branches. The first branch is: the refrigerant passes through the first throttle valve 61, and the first throttle valve 61 throttles and cools the refrigerant, turning it into low-temperature and low-pressure wet steam or supercooled liquid. The refrigerant continues to flow into the refrigeration box module 2. At this time, the first direct heat exchanger 21 of the refrigeration box module 2 acts as an evaporator, or the first direct heat exchanger 21 and the cold storage material are used together to cool the refrigeration box body 23, thereby absorbing the heat of the items and cooling the items, so that the refrigeration box module 2 can refrigerate the items. The refrigerant discharged from the outlet of the refrigeration box module 2 is a low-temperature and low-pressure fluid. The refrigerant continues to flow through the second throttle valve 62 and flows back to the compressor 11 for circulation. The second branch is: the refrigerant passes through the fifth throttle valve 65, the fifth throttle valve 65 throttles and cools the refrigerant, and turns it into low-temperature and low-pressure wet steam or supercooled liquid. The refrigerant continues to flow into the first in-vehicle heat exchanger 14. At this time, the high-temperature air in the vehicle passes through the first in-vehicle heat exchanger 14. The first in-vehicle heat exchanger 14 acts as an evaporator, and the refrigerant absorbs heat. The high-temperature air is cooled to low-temperature air for refrigeration in the vehicle. The refrigerant discharged from the outlet of the first in-vehicle heat exchanger 14 is a low-temperature and low-pressure fluid. The refrigerant continues to flow into the compressor 11 and circulates through the line.

[0186] When the air conditioning module 1 receives a cooling work request and the refrigeration box module 2 receives a cooling work request, only the cooling medium flow path of the air conditioning module 1 is opened in the thermal management system 100, that is, only the second branch is opened, and the evaporation pressure is matched to the cooling working pressure (for example, about 300 kPa) and evaporation temperature (for example, 0°C) of the air conditioning module 1. At this time, the cooling medium flow path of the refrigeration box module 2 is closed, that is, the first branch is closed, and the first fan 2333 in the refrigeration box is turned on to cool down the items in the refrigeration box 23 using the cold storage material. After the cooling mode of the air conditioning module 1 is turned on for a long period of time, and the first fan 2333 in the refrigeration box 23 works for a long time at the same time, the temperature of the cold storage material increases from -10°C to about 0°C. Subsequently, the refrigerant flow path of the refrigeration box module 2 is opened, that is, the above-mentioned first branch is opened. At this time, the refrigeration working pressure (for example, about 300 kPa) and evaporation temperature (for example, 0°C) of the air-conditioning module 1 keep the first fan 2333 working, and the refrigerant exchanges heat with the air in the refrigeration box 23 at the first direct heat exchanger 21 to maintain the refrigeration temperature of 0°C~10°C in the refrigeration box 23.

[0187] For example, refer to Fig.18 When the vehicle needs to be heated and the items need to be heated, the air conditioning module 1 is in the heating mode, the synchronous heating box module 3 is in the heating mode, the sixth throttle valve 66, the fourth throttle valve 64, the third throttle valve 63 and the first on-off valve 71 are opened, and the second on-off valve 72, the first throttle valve 61, the second throttle valve 62 and the fifth throttle valve 65 are closed. The refrigerant can be controlled to pass through the compressor 11 in sequence, and then branch. The first branch is the refrigerant passing through the second in-vehicle heat exchanger 12 and the sixth throttle valve 66 in sequence, and the second branch is the refrigerant passing through the fourth throttle valve 64, the heating box module 3 and the third throttle valve 63 in sequence. The outlet of the sixth throttle valve 66 and the outlet of the third throttle valve 63 in the two branches are merged. Then, the refrigerant flows into the compressor 11 along the outdoor heat exchanger 13 and the first on-off valve 71. The third throttle valve 63 and the sixth throttle valve 66 are opened to play a throttling role.

[0188] When the air conditioning module 1 is in the heating mode and the synchronous refrigeration box module 2 is heating, the refrigerant flow path is as follows: First, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas. Then, the refrigerant is divided into two branches. The first branch is: the refrigerant enters the second in-car heat exchanger 12. At this time, there is wind passing through the second in-car heat exchanger 12, and the refrigerant dissipates heat. The low-temperature air in the car passes through the second in-car heat exchanger 12 and is heated to high-temperature air for heating in the car. The refrigerant discharged from the outlet of the second in-car heat exchanger 12 is a medium-temperature and high-pressure fluid. Then, the refrigerant passes through the sixth throttle valve 66, and the sixth throttle valve 66 throttles and cools down, becoming low-temperature and low-pressure wet steam or supercooled liquid. The second branch is: the refrigerant continues to flow through the fourth throttle valve 64 and flows into the heating box module 3. At this time, the heating box module 3 acts as a condenser, and the refrigerant dissipates heat, thereby heating the items in the heating box body 33. The refrigerant discharged from the outlet of the heating box module 3 is a medium-temperature and high-pressure fluid. Next, the refrigerant passes through the third throttle valve 63, which throttles and cools the refrigerant, turning it into low-temperature, low-pressure wet steam or supercooled liquid. Subsequently, the refrigerants of the two branches merge and flow into the external heat exchanger 13, which is an evaporator at this time. The refrigerant is heated by the external environment through the external heat exchanger 13, completing the process of absorbing heat from the external environment. The refrigerant discharged from the outlet of the external heat exchanger 13 is a low-temperature, low-pressure fluid. Subsequently, the refrigerant continues to flow into the compressor 11 for circulation.

[0189] When the air conditioning module 1 receives a heating work request, and the heating box module 3 receives a heating work request at the same time, only the refrigerant flow path of the air conditioning module 1 for heating is opened in the thermal management system 100, that is, only the first branch is opened, and the refrigerant flow path of the heating box module 3 is closed, that is, the second branch is closed, and the second fan 3333 in the heating box is turned on to heat the items in the heating box 33 using the heat storage material. After the cooling mode of the air conditioning module 1 is turned on for a long period of time, and the second fan 3333 in the heating box 33 is operated for a long time at the same time, the temperature of the heat storage material is continuously reduced from 60°C to about 45°C. Subsequently, the refrigerant flow path of the heating box module 3 is opened, that is, the second branch is opened, and the second fan 3333 is kept working, and the heating temperature of 45°C in the heating box 33 is maintained by the refrigerant exchanging heat with the air in the heating box 33 at the second direct heat exchanger 31.

[0190] For example, refer to Fig.19When the articles need to be heated and cooled respectively, the refrigeration box module 2 is in the cooling mode, and the synchronous heating box module 3 is in the heating mode. The first throttle valve 61, the second throttle valve 62, the third throttle valve 63 and the fourth throttle valve 64 are opened, and the first on-off valve 71, the second on-off valve 72, the fifth throttle valve 65 and the sixth throttle valve 66 are closed. The refrigerant can be controlled to pass through the compressor 11, the fourth throttle valve 64, the heating box module 3 and the third throttle valve 63, the outdoor heat exchanger 13, the first throttle valve 61, the refrigeration box module 2 and the second throttle valve 62 in sequence, and then flow back to the compressor 11. The first throttle valve 61 is opened to play a throttling role, and the third throttle valve 63 is fully opened and used as a flow channel.

[0191] When the refrigeration box module 2 is in the cooling mode and the synchronous heating box module 3 is in the heating mode, the refrigerant refluxes as follows: First, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas. The refrigerant continues to flow through the fourth throttle valve 64 and flows into the heating box module 3. At this time, the heating box module 3 acts as a condenser, and the refrigerant dissipates heat, thereby heating the items in the heating box body 33. The refrigerant discharged from the outlet of the heating box module 3 is a medium-temperature and high-pressure fluid. Then, the refrigerant passes through the third throttle valve 63, and the third throttle valve 63 is fully opened and used as a flow channel. Next, the refrigerant passes through the outdoor heat exchanger 13, and at this time, the outdoor heat exchanger 13 is a condenser. The refrigerant is cooled by the outdoor environment through the outdoor heat exchanger 13, and the process of dissipating part of the heat to the outdoor environment is completed. Subsequently, the refrigerant passes through the first throttle valve 61, and the first throttle valve 61 throttles and cools the refrigerant. The refrigerant continues to flow into the refrigeration box module 2 to cool the items and cold storage material parts. The refrigerant continues to flow through the second throttle valve 62, and the low-temperature and low-pressure refrigerant flows back into the compressor 11 to circulate.

[0192] For example, refer to Fig. 20 When the thermal management system 100 is in the dehumidification mode of the air conditioning module 1, the second on-off valve 72 and the fifth throttle valve 65 are opened, and the first on-off valve 71, the first throttle valve 61, the second throttle valve 62, the third throttle valve 63 and the fourth throttle valve 64 are closed, so that the refrigerant can be controlled to pass through the compressor 11, the second in-vehicle heat exchanger 12, the second on-off valve 72, the external heat exchanger 13, the fifth throttle valve 65 and the first in-vehicle heat exchanger 14 in sequence, and then flow back to the compressor 11. The fifth throttle valve 65 is turned on to play the role of throttling.

[0193] The refrigerant reflux during dehumidification of the air conditioning module 1 is as follows: First, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas. Then, the refrigerant enters the second in-vehicle heat exchanger 12. At this time, the second in-vehicle heat exchanger 12 decides whether to start the air circulation according to actual needs, that is, whether there is wind passing through the second in-vehicle heat exchanger 12. Next, the refrigerant flows into the second in-vehicle heat exchanger 12, and the refrigerant in the second in-vehicle heat exchanger 12 releases heat according to demand. At this time, the refrigerant discharged from the outlet of the second in-vehicle heat exchanger 12 is still a high-temperature and high-pressure gas. The refrigerant continues to flow through the outdoor heat exchanger 13, and the refrigerant exchanges heat with the outdoor environment through the outdoor heat exchanger 13, and the refrigerant releases heat. The refrigerant discharged from the outlet of the outdoor heat exchanger 13 is a medium-temperature and high-pressure fluid (it should be noted that the fluid can be a liquid or a gas, which is determined by the temperature of the outdoor environment). Subsequently, the refrigerant passes through the fifth throttle valve 65, which throttles and cools the refrigerant, and turns it into low-temperature and low-pressure wet steam or supercooled liquid. The refrigerant continues to flow into the first in-vehicle heat exchanger 14. At this time, the high-temperature and humid air in the vehicle passes through the first in-vehicle heat exchanger 14, which acts as an evaporator. The high-temperature and humid air is cooled and condensed water is precipitated, and the relative humidity content in the vehicle decreases. After the first in-vehicle heat exchanger 14 dehumidifies the air in the vehicle, if temperature compensation is required, part of the refrigerant flowing through the second in-vehicle heat exchanger 12 can dissipate heat and heat the vehicle, so as to control the temperature in the vehicle while reducing the humidity in the vehicle. The refrigerant discharged from the outlet of the first in-vehicle heat exchanger 14 is a low-temperature and low-pressure fluid. The refrigerant continues to flow into the compressor 11, circulates, and is used.

[0194] For example, refer to Fig.21 When the thermal management system 100 is in the defog mode of the air conditioning module 1, the sixth throttle valve 66 and the first on-off valve 71 are opened, and the second on-off valve 72, the first throttle valve 61, the second throttle valve 62, the third throttle valve 63, the fourth throttle valve 64 and the fifth throttle valve 65 are closed, so that the refrigerant can be controlled to pass through the compressor 11, the second in-vehicle heat exchanger 12, the sixth throttle valve 66, the out-vehicle heat exchanger 13 and the first on-off valve 71 in sequence, and then flow back into the compressor 11. The sixth throttle valve 66 is opened to play a throttling role.

[0195] The refrigerant reflux of the air conditioning module 1 in the defog mode is as follows: First, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas. Then, the refrigerant enters the second in-vehicle heat exchanger 12. At this time, there is wind passing through the second in-vehicle heat exchanger 12. The low-temperature air in the vehicle passes through the second in-vehicle heat exchanger 12 and is heated to high-temperature air. The high-temperature air is blown onto the glass of the vehicle through the air duct of the vehicle (not shown) to blow away the fog beads on the glass of the vehicle. The refrigerant is cooled when passing through the first in-vehicle condenser, and the refrigerant discharged from the outlet of the second in-vehicle heat exchanger 12 is a medium-temperature and high-pressure fluid. Then, the refrigerant passes through the sixth throttle valve 66, and the sixth throttle valve 66 throttles and cools down, becoming a low-temperature and low-pressure wet steam or a supercooled liquid. Subsequently, the refrigerant passes through the outdoor heat exchanger 13, which is an evaporator. The refrigerant is heated by the outdoor environment, and heat absorption from the outdoor environment is completed. The refrigerant discharged from the outlet of the outdoor heat exchanger 13 is a low-temperature and low-pressure fluid. Then, the refrigerant continues to flow into the compressor 11, circulates, and is used.

[0196] According to some embodiments of the present invention, referring to Fig.24 and Fig.25 The thermal management system 100 further includes a motor module 4 , which includes a three-way valve 41 , a motor 42 , a motor heat exchanger 43 and a plate heat exchanger 44 .

[0197] Specifically, the three-way valve 41 includes a first connection port 411, a second connection port 412, and a third connection port 413. The cooling module of the motor 42 is connected to the first connection port 411, and one end of the motor heat exchanger 43 is connected to the second connection port 412. The first end 441 of the plate heat exchanger 44 is connected to the third connection port 413, the other end of the motor heat exchanger 43 is connected to the first end 441 of the plate heat exchanger 44, and the second end 442 of the plate heat exchanger 44 is connected to the cooling module of the motor 42. For example, in Fig.24 and Fig.25 In the example, one end of the cooling module of the motor 42 is connected to the first connection port 411, and the other end of the cooling module of the motor 42 is connected to the second end 442 of the plate heat exchanger 44, and the second end 442 of the plate heat exchanger 44 can be selectively connected to the second connection port 412 and one of the other ends of the motor heat exchanger 43.

[0198] After the motor 42 of the motor module 4 has been working for a period of time, the temperature of the motor 42 is relatively high. The motor module 4 can also be in the following different use states according to the use of the thermal management system 100:

[0199] First, as Fig.34As shown, when the plate heat exchanger 44 does not need to exchange heat, the plate heat exchanger 44 acts as a flow channel. The first connection port 411 and the second connection port 412 are opened, and the third connection port 413 is closed. After the motor 42 has been working for a period of time, the temperature of the motor 42 is relatively high. The fluid (such as coolant) in the cooling module of the motor 42 flows to the plate heat exchanger 44 and the motor heat exchanger 43 in turn, and the fluid dissipates heat in the motor heat exchanger 43, and the temperature is reduced. Then, the fluid continues to flow along the second connection port 412 and the first connection port 411 to the cooling module of the motor 42, forming a cycle, and the fluid with a lower temperature can take away the heat of the motor 42, so that the temperature of the motor 42 is reduced.

[0200] Second, if Fig.35 As shown, when the plate heat exchanger 44 needs to exchange more heat, it absorbs all the waste heat of the motor 42. The first connection port 411 and the third connection port 413 are opened, and the second connection port 412 is closed. The fluid flows from the cooling module of the motor 42 to the plate heat exchanger 44, and the fluid dissipates heat in the plate heat exchanger 44, and the temperature decreases. Then, the fluid continues to flow along the third connection port 413 and the first connection port 411 to the cooling module of the motor 42, forming a cycle.

[0201] Third, if Fig.36 As shown, when the plate heat exchanger 44 needs to exchange less heat, it absorbs part of the waste heat of the motor 42, and the other part of the waste heat of the motor 42 is dissipated through the motor heat exchanger 43. The first connection port 411 and the second connection port 412 are opened, and the third connection port 413 is closed. The fluid in the cooling module of the motor 42 flows to the plate heat exchanger 44, and the fluid dissipates heat in the plate heat exchanger 44, and the temperature decreases. Then, the fluid continues to flow into the motor heat exchanger 43, and the fluid dissipates heat in the motor heat exchanger 43, and the fluid temperature continues to decrease. Subsequently, the fluid continues to flow along the second connection port 412 and the first connection port 411 to the cooling module of the motor 42, forming a cycle.

[0202] With such a configuration, compared with the external heat exchanger 13, when the temperature outside the vehicle is low, the heat absorption of the external heat exchanger 13 may be insufficient. By adding the plate heat exchanger 44 in the motor module 4, heat can be absorbed from the external environment and the motor 42, increasing the amount of absorbed heat and improving the heat absorption capacity of the thermal management system 100, thereby improving the heating capacity of the thermal management system 100, which is beneficial for the thermal management system 100 to be used normally for a long time at a lower temperature. Moreover, the utilization rate of the heat generated by the motor 42 is also improved to avoid energy waste.

[0203] According to some embodiments of the present invention, referring to Fig.24 and Fig.25The thermal management system 100 further includes a battery pack heat exchanger 5, one end of the battery pack heat exchanger 5 is selectively connected to one of the third end 443 of the plate heat exchanger 44 and the other end of the external heat exchanger 13, the other end of the battery pack heat exchanger 5 is selectively connected to one of the inlet and the outlet of the compressor 11, and the fourth end 444 of the plate heat exchanger 44 is connected to the inlet of the compressor 11. For example, Fig.24 In the example, one end of the battery pack heat exchanger 5 can be selectively connected to the third end 443 of the plate heat exchanger 44 and the outlet end of the external heat exchanger 13. When one end of the battery pack heat exchanger 5 is connected to the outlet end of the external heat exchanger 13 and the other end of the battery pack is connected to the inlet of the compressor 11, the battery pack heat exchanger 5 can be in cooling mode. When the other end of the battery pack heat exchanger 5 is connected to the inlet of the compressor 11 and one end of the battery pack heat exchanger 5 is connected to the third end 443 of the plate heat exchanger 44, the battery pack heat exchanger 5 can be in cooling mode. It should be noted that the battery pack heat exchanger 5 is in contact with the battery of the vehicle.

[0204] Combination Fig.39 The working states of the air conditioning module 1, the refrigeration box module 2 and the battery pack heat exchanger 5 may include the following situations:

[0205] First, when the air-conditioning module 1 and the battery pack heat exchanger 5 are not working, for example, when the vehicle is parked, the direct heat exchanger 21 of the refrigeration box module 2 is not turned on to cool the load in the refrigeration box 23, but the refrigerant flows through the indirect heat exchanger 22 of the refrigeration box module 2. At this time, the evaporation pressure is matched to the working pressure of the refrigeration box (about 200 kPa, evaporation temperature -10°C), that is, the indirect heat exchanger 22 of the refrigeration box module 2 is turned on to cool the cold storage material so that the temperature of the cold storage material reaches the refrigeration temperature requirement of the refrigerator.

[0206] Second, when the passenger enters the passenger compartment and turns on the cooling mode of the air conditioning module 1 and (or) the cooling mode of the battery pack heat exchanger 5, the thermal management system 100 only turns on the cooling flow path of the air conditioning module 1 and (or) the cooling flow path of the battery pack heat exchanger 5, that is, the refrigerant flows through the first in-vehicle heat exchanger 14 to cool the interior of the vehicle, and (or) the refrigerant flows through the battery pack heat exchanger 5 to cool the battery, and the refrigerant does not flow through the refrigeration box module 2. In this process, the evaporation pressure can be matched to the required working pressure of the air conditioning module 1 (about 300kPa, evaporation temperature 0°C), and when the refrigeration box has a refrigeration demand, the cold storage material cools the box, that is, the cold storage material cools the box.

[0207] Third, when the refrigerator module 2 receives a work request, and the air conditioning module 1 receives a cooling mode and (or) the battery pack heat exchanger 5 receives a cooling work request, the thermal management system 100 can only turn on the cooling mode of the air conditioning module 1 and (or) the cooling mode of the battery pack heat exchanger 5, and the cooling circuit of the refrigerator module 2 is not turned on. At this time, the coldness of the cold storage material can be used to cool down the items. After the air conditioning module 1 and (or) the battery pack heat exchanger 5 and the cold storage material of the refrigerator module 2 have been working for a long period of time, the temperature increase of the cold storage material (for example, from -10°C to about 0°C) is not enough to play a cooling role. The cooling circuit of the refrigerator module 2 is turned on, and the first direct heat exchanger 21 is used for heat exchange to maintain the refrigeration temperature of the refrigerator module 2 (for example, 0~10°C).

[0208] Fourth, when the refrigeration box module 2 receives a work request alone, that is, when only the refrigeration box module 2 is in the refrigeration mode, the evaporation pressure of the refrigerant matches the working pressure of the refrigeration box (about 200 kPa, evaporation temperature -10°C), and the refrigerant exchanges heat with the air flowing to the direct heat exchanger 21 of the refrigeration box module 2 when flowing through the direct heat exchanger 21 of the refrigeration box module 2, and the direct heat exchanger 21 of the refrigeration box module 2 cools. When the refrigerant flows through the indirect heat exchanger 22 of the refrigeration box module 2, a part of the cold energy is stored in the cold storage material through the indirect heat exchanger 22 of the refrigeration box module 2.

[0209] Combination Fig.40 The working states of the air conditioning module 1, the heating box module 3 and the battery pack heat exchanger 5 may include the following situations:

[0210] First, when the air conditioning module 1 and (or) the battery pack heat exchanger 5 are not working, for example, when the vehicle is parked, the direct heat exchanger 31 of the heating box module 3 is not turned on to heat up the load in the heating box body 33, but the refrigerant flows through the indirect heat exchanger 32 of the heating box module 3. At this time, the inlet temperature of the indirect heat exchanger 32 of the heating box module 3 is matched to the working temperature of the heating box (about 60°C), that is, the indirect heat exchanger 32 of the heating box module 3 is turned on to heat up the heat storage material component, so that the temperature of the heat storage material component reaches the heating temperature requirement of the refrigerator.

[0211] Second, when the passenger enters the passenger compartment and turns on the heating mode of the air conditioning module 1 and (or) the cooling mode of the battery pack heat exchanger 5, the thermal management system 100 only turns on the heating flow path of the air conditioning module 1 and (or) the cooling flow path of the battery pack heat exchanger 5, that is, the refrigerant flows through the second in-vehicle heat exchanger 12 to heat the interior of the vehicle, and (or) the refrigerant flows through the battery pack heat exchanger 5 to heat the battery, and the refrigerant does not flow through the heating box module 3. In this process, the evaporation pressure can be matched to the working pressure required by the air conditioning module 1, and when the heating box has a heating demand, the heat of the heat storage material component heats the box, that is, the heat storage material component heats.

[0212] Third, when the heating box module 3 receives a work request, and the air conditioning module 1 receives a work request for the heating mode and (or) the battery pack heat exchanger 5 receives a work request for the cooling mode, the thermal management system 100 can only turn on the heating mode of the air conditioning module 1 and (or) the cooling mode of the battery pack heat exchanger 5, and the heating circuit of the heating box module 3 is not turned on. At this time, the heat of the heat storage material can be used to heat the object. After the air conditioning module 1 and (or) the battery pack heat exchanger 5 and the heat storage material of the heating box module 3 have worked for a long period of time, the temperature of the heat storage material has dropped (for example, from 60°C to about 45°C) and is not enough to play a heating and cooling role. The heating circuit of the heating box module 3 is turned on, and the heat distribution of the thermal management system 100 pre-guarantees the heating of the air conditioning module 1 and (or) the cooling of the battery pack heat exchanger 5, and the heat exchange of the second direct heat exchanger 31 is used to maintain the heating temperature of the heating box module 2 (for example, 45°C).

[0213] Fourth, when the heating box module 3 receives a work request alone, that is, when only the heating box module 3 is in the heating mode, the temperature of the refrigerant at the inlet of the direct heat exchanger 31 of the heating box module 3 is matched to the working temperature of the heating box (about 60°C), and the refrigerant exchanges heat with the air flowing to the direct heat exchanger 31 of the heating box module 3 when flowing through the direct heat exchanger 31 of the heating box module 3, and the direct heat exchanger 31 of the heating box module 3 cools. When the refrigerant flows through the indirect heat exchanger 32 of the heating box module 3, part of the heat is stored in the heat storage material through the indirect heat exchanger 22 of the heating box module 3.

[0214] With such a configuration, the battery pack heat exchanger 5 can exchange heat with the battery. When the battery temperature rises, the battery pack heat exchanger 5 can absorb the heat of the battery to reduce the battery temperature. When the battery temperature is low, the battery pack heat exchanger 5 provides heat to the battery to increase the battery temperature, thereby enabling the battery to be used normally for a long time. In addition, when the battery pack heat exchanger 5 is used simultaneously with the air conditioning module 1 and the heating box module 3, the battery pack heat exchanger 5 is used in conjunction with the plate heat exchanger 44, which solves the problem of cold capacity mismatch between functions of different temperature control, thereby making the distribution of the refrigerant more reasonable, effectively ensuring that the air conditioning module 1, the heating box module 3 and the battery pack heat exchanger 5 can be used normally, making the thermal management system 100 more matched as a whole, thereby ensuring the normal operation of the thermal management system 100.

[0215] According to some embodiments of the present invention, referring to Fig.24 The thermal management system 100 further includes a seventh throttle valve 67 and an eighth throttle valve 68. One end of the seventh throttle valve 67 is connected to one end of the battery pack heat exchanger 5, and the other end of the seventh throttle valve 67 is selectively connected to one of the third end 443 of the plate heat exchanger 44 and the other end of the off-vehicle heat exchanger 13. The eighth throttle valve 68 is connected between the other end of the battery pack heat exchanger 5 and the inlet and outlet of the compressor 11.

[0216] For example, in Fig.24 In the example, the seventh throttle valve 67 and the eighth throttle valve 68 are respectively located at the two ends of the battery pack heat exchanger 5, and the battery pack heat exchanger 5 can be selectively connected to one of the inlet and outlet of the compressor 11 through the eighth throttle valve 68. Therefore, by controlling the seventh throttle valve 67 and the eighth throttle valve 68, it is possible to control whether the battery pack heat exchanger 5 is working, so as to facilitate the selection of whether to start the cooling or refrigeration mode of the battery pack heat exchanger 5 according to the use of the battery, thereby improving the use flexibility of the battery pack heat exchanger 5, and further improving the use flexibility of the thermal management system 100.

[0217] According to some embodiments of the present invention, referring to Fig.24 The thermal management system 100 further includes a third on-off valve 73 and a fourth on-off valve 74 .

[0218] Specifically, the third on-off valve 73 is connected between the outlet of the compressor 11 and the eighth throttle valve 68. The fourth on-off valve 74 is connected between the inlet of the compressor 11 and the eighth throttle valve 68. For example, the third on-off valve 73 and the fourth on-off valve 74 can be solenoid valves, respectively. But not limited thereto.

[0219] It should be noted that in Fig.26 and Fig. 27 In the example, the dotted line is the flow route of the refrigerant in the air-conditioning module 11, and the direction indicated by the arrow is the flow direction of the refrigerant.

[0220] For example, refer to Fig.26 When the battery pack needs to be cooled, the battery pack heat exchanger 5 is in cooling mode, the second on-off valve 72, the seventh throttle valve 67, the eighth throttle valve 68 and the fourth on-off valve 74 are opened, and the third on-off valve 73 is closed. The refrigerant passes through the compressor 11, the second in-vehicle heat exchanger 12, the external heat exchanger 13, the seventh throttle valve 67, the battery pack heat exchanger 5, the eighth throttle valve 68 and the fourth on-off valve 74 in sequence, and then the refrigerant flows back to the compressor 11. The seventh throttle valve 67 plays a throttling role. For example, the eighth throttle valve 68 can be a large-caliber electronic expansion valve.

[0221] The refrigerant reflux when the battery pack heat exchanger 5 is in cooling mode is as follows: First, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas. Then, the refrigerant enters the second in-vehicle heat exchanger 12. At this time, there is no wind passing through the second in-vehicle heat exchanger 12, and it only flows as a flow channel. At this time, the refrigerant discharged from the outlet of the second in-vehicle heat exchanger 12 is still a high-temperature and high-pressure gas. The refrigerant continues to flow through the external heat exchanger 13, and the refrigerant exchanges heat with the external environment through the external heat exchanger 13. The refrigerant releases heat, and the refrigerant discharged from the outlet of the external heat exchanger 13 is a medium-temperature and high-pressure fluid (it should be noted that the fluid can be a liquid or a gas, which is determined by the temperature of the external environment). Then, the refrigerant flows to the seventh throttle valve 67, and the refrigerant passes through the seventh throttle valve 67. The seventh throttle valve 67 throttles and cools the refrigerant, turning it into a low-temperature and low-pressure wet steam or a supercooled liquid. Subsequently, the refrigerant flows into the battery pack heat exchanger 5, which acts as an evaporator to cool the battery pack, and the refrigerant discharged from the outlet of the battery pack heat exchanger 5 is a low-temperature and low-pressure fluid. The refrigerant continues to flow, passing through the eighth throttle valve 68 and the compressor 11 in sequence, and circulates.

[0222] For example, refer to Fig. 27 When the battery pack needs to be heated, the battery pack heat exchanger 5 is in cooling mode, the third on-off valve 73, the seventh throttle valve 67, the eighth throttle valve 68 and the first on-off valve 71 are opened, and the fourth on-off valve 74 is closed. The refrigerant passes through the compressor 11, the third on-off valve 73, the eighth throttle valve 68, the battery pack heat exchanger 5, the seventh throttle valve 67, the plate heat exchanger 44 and the first on-off valve 71 in sequence, and then the refrigerant flows back to the compressor 11. The seventh throttle valve 67 plays a throttling role.

[0223] The refrigerant reflux when the battery pack heat exchanger 5 is in the cooling mode is as follows: First, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas. After the refrigerant continues to flow through the third on-off valve 73 and the eighth throttle valve 68, it flows into the battery pack heat exchanger 5. The low-temperature fluid passes through the battery pack heat exchanger 5 for heat exchange, so that the temperature of the battery absorbs the heat of the refrigerant and increases. After passing through the battery pack heat exchanger 5, the refrigerant is cooled into a medium-temperature and high-pressure fluid. Next, the refrigerant flows to the seventh throttle valve 67, which throttles and cools the refrigerant, turning it into low-temperature and low-pressure wet steam or supercooled liquid. Subsequently, the refrigerant flows into the plate heat exchanger 44. At this time, the plate heat exchanger 44 acts as an evaporator, and the refrigerant is heated by the waste heat of the outside environment or the motor 42, completing the process of absorbing heat from the outside environment. The refrigerant discharged from the outlet of the plate heat exchanger 44 is a low-temperature and low-pressure fluid. The refrigerant continues to flow, passing through the first on-off valve 71 and the compressor 11 in sequence, and circulates.

[0224] In this configuration, by controlling the third on-off valve 73 and the fourth on-off valve 74, the refrigerant passes through the battery pack heat exchanger 5 to cool and heat the battery pack of the vehicle, thereby reducing the difficulty of cooling and heating the battery pack, improving the cooling and heating rate of the battery pack, and extending the service life of the battery pack. In addition, the thermal management system 100 can cool and heat the battery pack according to the temperature of the battery pack, thereby further improving the applicability of the thermal management system 100.

[0225] It should be noted that the first throttle valve 61, the second throttle valve 62, the third throttle valve 63, the fourth throttle valve 64, the fifth throttle valve 65, the sixth throttle valve 66, the seventh throttle valve 67, the eighth throttle valve 68, the first on-off valve 71, the second on-off valve 72, the third on-off valve 73 and the fourth on-off valve 74 cooperate with each other, and the thermal management system 100 can also realize the following modes: First, the air conditioning module 1 is in the cooling mode, and the synchronous battery pack heat exchanger 5 is in the cooling mode (such as Fig.28 Second, the refrigeration box module 2 is in the cooling mode, and the synchronous battery pack heat exchanger 5 is in the cooling mode (as shown in FIG. Fig.29 Third, the air conditioning module 1 is in cooling mode, the battery pack heat exchanger 5 is in cooling mode, and the refrigeration box module 2 is in cooling mode (as shown). Fig.30 Fourth, the air conditioning module 1 is in the heating mode, and the synchronous battery pack heat exchanger 5 is in the cooling mode (as shown). Fig.31 Fifth, the refrigeration box module 2 is in heating mode, and the synchronous battery pack heat exchanger 5 is in cooling mode (as shown). Fig.32 Sixth, the air conditioning module 1 is in heating mode, the synchronous refrigeration box module 2 is in heating mode and the battery pack heat exchanger 5 is in cooling mode (as shown). Fig.33 ). Fig.28 , Fig.29 , Fig.30 , Fig.31 , Fig.32 and Fig.33 In the example, the dotted line is the flow route of the refrigerant in the air-conditioning module 1, and the direction indicated by the arrow is the flow direction of the refrigerant.

[0226] For example, refer to Fig.28When the vehicle needs to be cooled and the battery pack needs to be cooled, the air conditioning module 1 is in the cooling mode, and the battery pack heat exchanger 5 is in the cooling mode. The second on-off valve 72, the seventh throttle valve 67, the eighth throttle valve 68, the fourth on-off valve 74 and the fifth throttle valve 65 are opened, the sixth throttle valve 66 is closed, the fourth throttle valve 64, the third throttle valve 63, the third on-off valve 73, the first on-off valve 71, the first throttle valve 61 and the second throttle valve 62 are closed. The refrigerant can be controlled to pass through the compressor 11, the second in-vehicle heat exchanger 12, the second on-off valve 72 and the external heat exchanger 13 in sequence, and then branch. The first branch is that the refrigerant passes through the second on-off valve 72, the seventh throttle valve 67, the battery pack heat exchanger 5, and the eighth throttle valve 68 in sequence, and flows back to the compressor 11. The second branch is that the refrigerant passes through the fifth throttle valve 65 and the first in-vehicle heat exchanger 14 in sequence, and flows back to the compressor 11. The fifth throttle valve 65 and the seventh throttle valve 67 respectively play a throttling role.

[0227] When the air conditioning module 1 is in cooling mode and the synchronous battery pack heat exchanger 5 is in cooling mode, the refrigerant refluxes as follows: First, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas. Then, the refrigerant enters the second in-vehicle heat exchanger 12. At this time, there is no wind passing through the second in-vehicle heat exchanger 12, and it only flows as a flow channel. The refrigerant discharged from the outlet of the second in-vehicle heat exchanger 12 is still a high-temperature and high-pressure gas. Next, the refrigerant flows to the outdoor heat exchanger 13 through the second on-off valve 72. The refrigerant exchanges heat with the outdoor environment through the outdoor heat exchanger 13, and the refrigerant releases heat. The refrigerant discharged from the outlet of the outdoor heat exchanger 13 is a medium-temperature and high-pressure fluid (it should be noted that the fluid can be a liquid or a gas, which is determined by the temperature of the outdoor environment).

[0228] After passing through the off-board heat exchanger 13, the refrigerant is divided into two branches. The first branch is: the refrigerant flows to the seventh throttle valve 67, which throttles and cools the refrigerant to low-temperature, low-pressure wet steam or supercooled liquid. Subsequently, the refrigerant continues to flow into the battery pack heat exchanger 5. At this time, the battery pack heat exchanger 5 acts as an evaporator. The high-temperature fluid from the battery pack is cooled down to a low-temperature fluid through the battery pack heat exchanger 5, and then provided to the battery pack for refrigeration. The refrigerant at the outlet of the battery pack heat exchanger 5 is a low-temperature, low-pressure fluid. The refrigerant continues to flow to the eighth throttle valve 68 and the fourth on-off valve 74 in sequence. The second branch is: the refrigerant passes through the fifth throttle valve 65, the fifth throttle valve 65 throttles and cools the refrigerant, and turns it into low-temperature and low-pressure wet steam or supercooled liquid. The refrigerant continues to flow into the first in-vehicle heat exchanger 14. At this time, the high-temperature air in the vehicle passes through the first in-vehicle heat exchanger 14. The first in-vehicle heat exchanger 14 acts as an evaporator, and the refrigerant absorbs heat. The high-temperature air is cooled to low-temperature air for refrigeration in the vehicle. The refrigerant discharged from the outlet of the first in-vehicle heat exchanger 14 is a low-temperature and low-pressure fluid. After the outlet of the first in-vehicle heat exchanger 14 and the outlet of the fourth on-off valve 74 are merged, the refrigerant continues to flow into the compressor 11, circulates, and is used.

[0229] For example, refer to Fig.29 When the items need to be refrigerated and the battery pack needs to be cooled, the refrigeration box module 2 is in the refrigeration mode, and the battery pack heat exchanger 5 is in the refrigeration mode. The second on-off valve 72, the seventh throttle valve 67, the eighth throttle valve 68, the fourth on-off valve 74, the first throttle valve 61 and the second throttle valve 62 are opened, the sixth throttle valve 66 is closed, and the fourth throttle valve 64, the third throttle valve 63, the third on-off valve 73, the first on-off valve 71 and the fifth throttle valve 65 are closed. The refrigerant can be controlled to pass through the compressor 11, the second in-vehicle heat exchanger 12, the second on-off valve 72 and the external heat exchanger 13 in sequence, and then branch. The first branch is the refrigerant passing through the second on-off valve 72, the seventh throttle valve 67, the battery pack heat exchanger 5, the eighth throttle valve 68 and the fourth on-off valve 74 in sequence, and then flowing back to the compressor 11. The second branch is the refrigerant passing through the first throttle valve 61, the refrigeration box module 2 and the second throttle valve 62 in sequence, and then flowing back to the compressor 11. The first throttle valve 61 and the seventh throttle valve 67 respectively play a throttling role.

[0230] When the refrigeration box module 2 is in the cooling mode and the synchronous battery pack heat exchanger 5 is in the cooling mode, the refrigerant refluxes as follows: First, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas. Then, the refrigerant enters the second in-vehicle heat exchanger 12. At this time, there is no wind passing through the second in-vehicle heat exchanger 12, and it only flows as a flow channel. The refrigerant discharged from the outlet of the second in-vehicle heat exchanger 12 is still a high-temperature and high-pressure gas. Next, the refrigerant flows to the outdoor heat exchanger 13 through the second on-off valve 72. The refrigerant exchanges heat with the outdoor environment through the outdoor heat exchanger 13, and the refrigerant releases heat. The refrigerant discharged from the outlet of the outdoor heat exchanger 13 is a medium-temperature and high-pressure fluid (it should be noted that the fluid can be a liquid or a gas, which is determined by the temperature of the outdoor environment).

[0231] After passing through the off-board heat exchanger 13, the refrigerant is divided into two branches. The first branch is: the refrigerant flows to the seventh throttle valve 67, and the seventh throttle valve 67 throttles and cools the refrigerant to become low-temperature, low-pressure wet steam or supercooled liquid. Subsequently, the refrigerant continues to flow into the battery pack heat exchanger 5. At this time, the battery pack heat exchanger 5 acts as an evaporator. The high-temperature fluid from the battery pack is cooled down to a low-temperature fluid through the battery pack heat exchanger 5, and is provided to the battery pack for refrigeration. The refrigerant continues to flow to the eighth throttle valve 68 and the fourth on-off valve 74 in sequence. The second branch is: the refrigerant passes through the fifth throttle valve 65, and the fifth throttle valve 65 throttles and cools the refrigerant to become low-temperature, low-pressure wet steam or supercooled liquid. The refrigerant continues to flow into the refrigeration box module 2. At this time, the refrigeration box module 2 acts as an evaporator, thereby absorbing the heat of the items and cooling the items, realizing the refrigeration of the items by the refrigeration box module 2. The refrigerant discharged from the outlet of the refrigeration box module 2 is a low-temperature, low-pressure fluid. After the outlet of the refrigeration box module 2 and the outlet of the fourth on-off valve 74 merge, the refrigerant continues to flow into the compressor 11 and circulates.

[0232] For example, refer to Fig.30When the interior of the vehicle needs to be cooled, the battery pack needs to be cooled, and the items need to be cooled, the air conditioning module 1 is in cooling mode, the battery pack heat exchanger 5 is in cooling mode, and the refrigeration box module 2 is in cooling mode, the second on-off valve 72, the seventh throttle valve 67, the eighth throttle valve 68, the fourth on-off valve 74, the fifth throttle valve 65, the first throttle valve 61 and the second throttle valve 62 are opened, the sixth throttle valve 66 is closed, the fourth throttle valve 64, the third throttle valve 63, the third on-off valve 73 and the first on-off valve 71 are closed. The refrigerant can be controlled to pass through the compressor 11, the second in-vehicle heat exchanger 12, the second on-off valve 72 and the outdoor heat exchanger 13 in sequence, and then branch. The first branch is that the refrigerant passes through the second on-off valve 72, the seventh throttle valve 67, the battery pack heat exchanger 5, the eighth throttle valve 68 and the fourth on-off valve 74 in sequence, and flows back to the compressor 11. The second branch is that the refrigerant passes through the fifth throttle valve 65 and the first in-vehicle heat exchanger 14 in sequence, and flows back to the compressor 11. The third branch is that the refrigerant passes through the first throttle valve 61, the refrigeration box module 2 and the second throttle valve 62 in sequence, and flows back to the compressor 11. The first throttle valve 61, the fifth throttle valve 65 and the seventh throttle valve 67 play the role of throttling respectively.

[0233] When the air conditioning module 1 is in cooling mode, the synchronous battery pack heat exchanger 5 is in cooling mode, and the refrigeration box module 2 is in cooling mode, the refrigerant refluxes as follows: First, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas. Then, the refrigerant enters the second in-vehicle heat exchanger 12. At this time, there is no wind passing through the second in-vehicle heat exchanger 12, and it only flows as a flow channel. The refrigerant discharged from the outlet of the second in-vehicle heat exchanger 12 is still a high-temperature and high-pressure gas. Then, the refrigerant flows to the outdoor heat exchanger 13 through the second on-off valve 72. The refrigerant exchanges heat with the outdoor environment through the outdoor heat exchanger 13, and the refrigerant releases heat. The refrigerant discharged from the outlet of the outdoor heat exchanger 13 is a medium-temperature and high-pressure fluid (it should be noted that the fluid can be a liquid or a gas, which is determined by the temperature of the outdoor environment).

[0234] After passing through the off-board heat exchanger 13, the refrigerant is divided into three branches. The first branch is: the refrigerant flows to the seventh throttle valve 67, and the seventh throttle valve 67 throttles and cools the refrigerant to become low-temperature, low-pressure wet steam or supercooled liquid. Subsequently, the refrigerant continues to flow into the battery pack heat exchanger 5. At this time, the battery pack heat exchanger 5 acts as an evaporator. The high-temperature fluid from the battery pack is cooled down to a low-temperature fluid through the battery pack heat exchanger 5, and then provided to the battery pack for refrigeration. The refrigerant at the outlet of the battery pack heat exchanger 5 is a low-temperature, low-pressure fluid. The refrigerant continues to flow to the eighth throttle valve 68 and the fourth on-off valve 74 in turn. The second branch is: the refrigerant passes through the fifth throttle valve 65, and the fifth throttle valve 65 throttles and cools the refrigerant to become low-temperature, low-pressure wet steam or supercooled liquid. The refrigerant continues to flow into the first in-vehicle heat exchanger 14. At this time, the high-temperature air in the vehicle passes through the first in-vehicle heat exchanger 14. The first in-vehicle heat exchanger 14 acts as an evaporator. The refrigerant absorbs heat, and the high-temperature air is cooled to low-temperature air for refrigeration in the vehicle. The refrigerant discharged from the outlet of the first in-vehicle heat exchanger 14 is a low-temperature and low-pressure fluid. The third branch is: the refrigerant passes through the fifth throttle valve 65, and the fifth throttle valve 65 throttles and cools the refrigerant to become low-temperature and low-pressure wet steam or supercooled liquid. The refrigerant continues to flow into the refrigeration box module 2. At this time, the refrigeration box module 2 acts as an evaporator, thereby absorbing the heat of the items, cooling the items, and realizing the refrigeration of the items by the refrigeration box module 2. The refrigerant discharged from the outlet of the refrigeration box module 2 is a low-temperature and low-pressure fluid. After the outlet of the refrigeration box module 2, the outlet of the first in-vehicle heat exchanger 14, and the outlet of the fourth on-off valve 74 are merged, the refrigerant continues to flow into the compressor 11 for circulation.

[0235] For example, refer to Fig.31 When the vehicle needs to be heated and the battery pack needs to be heated, the air conditioning module 1 is in the heating mode, and the synchronous battery pack heat exchanger 5 is in the cooling mode. The sixth throttle valve 66, the seventh throttle valve 67, the eighth throttle valve 68, the third on-off valve 73 and the first on-off valve 71 are opened, and the second on-off valve 72, the fourth throttle valve 64, the third throttle valve 63, the fourth on-off valve 74, the fifth throttle valve 65, the first throttle valve 61 and the second throttle valve 62 are closed. The refrigerant can be controlled to pass through the compressor 11 in sequence, and then branch. The first branch is the refrigerant passing through the second in-vehicle heat exchanger 12 and the sixth throttle valve 66 in sequence. The second branch is the refrigerant passing through the third on-off valve 73, the eighth throttle valve 68, the battery pack heat exchanger 5 and the seventh throttle valve 67 in sequence. The refrigerant merges at the outlet of the sixth throttle valve 66 and the outlet of the seventh throttle valve 67. Subsequently, the refrigerant passes through the plate heat exchanger 44 and the first on-off valve 71 in sequence and flows into the compressor 11. The sixth throttle valve 66 and the seventh throttle valve 67 each play a throttling role.

[0236] When the air conditioning module 1 is in the heating mode and the synchronous battery pack heat exchanger 5 is in the cooling mode, the refrigerant refluxes as follows: First, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas. After passing through the compressor 11, the refrigerant is divided into two branches. The first branch is: the refrigerant enters the second in-vehicle heat exchanger 12. At this time, there is wind passing through the second in-vehicle heat exchanger 12, and the refrigerant dissipates heat. The low-temperature air in the car passes through the second in-vehicle heat exchanger 12 and is heated to high-temperature air to supply the car for heating. The refrigerant discharged from the outlet of the second in-vehicle heat exchanger 12 is a medium-temperature and high-pressure fluid. Next, the refrigerant passes through the sixth throttle valve 66, and the sixth throttle valve 66 throttles and cools down, turning into low-temperature and low-pressure wet steam or supercooled liquid. The second branch is: the refrigerant continues to flow through the third on-off valve 73 and the eighth throttle valve 68, and then flows into the battery pack heat exchanger 5. The low-temperature battery pack absorbs the heat of the refrigerant through the battery pack heat exchanger 5, and the temperature rises. After passing through the battery pack heat exchanger 5, the refrigerant is cooled into a medium-temperature and high-pressure fluid. Then, the refrigerant flows to the seventh throttle valve 67, which throttles and cools the refrigerant, turning it into a low-temperature and low-pressure wet steam or supercooled liquid. The refrigerant merges at the outlet of the sixth throttle valve 66 and the outlet of the seventh throttle valve 67. Subsequently, the refrigerant flows into the plate heat exchanger 44, at which time the plate heat exchanger 44 acts as an evaporator, and the refrigerant is heated by the waste heat of the outside environment or the motor 42, completing the process of absorbing heat from the outside environment. The refrigerant discharged from the outlet of the plate heat exchanger 44 is a low-temperature and low-pressure fluid. The refrigerant continues to flow, passing through the first on-off valve 71 and the compressor 11 in sequence, and circulates.

[0237] For example, refer to Fig.32 When the items need to be heated and the battery pack needs to be heated, the refrigeration box module 2 is in the heating mode, and the synchronous battery pack heat exchanger 5 is in the cooling mode. The seventh throttle valve 67, the eighth throttle valve 68, the third on-off valve 73, the first on-off valve 71, the fourth throttle valve 64 and the third throttle valve 63 are opened, the sixth throttle valve 66 is closed, and the second on-off valve 72, the fourth on-off valve 74, the fifth throttle valve 65, the first throttle valve 61 and the second throttle valve 62 are closed. The refrigerant can be controlled to pass through the compressor 11 in sequence and then branch. The first branch is the refrigerant passing through the fourth throttle valve 64, the heating box module 3 and the third throttle valve 63 in sequence. The second branch is the refrigerant passing through the third on-off valve 73, the eighth throttle valve 68, the battery pack heat exchanger 5 and the seventh throttle valve 67 in sequence. The refrigerant merges at the outlet of the third throttle valve 63 and the outlet of the seventh throttle valve 67. Then, the refrigerant passes through the plate heat exchanger 44 and the first on-off valve 71 in sequence and flows into the compressor 11. The third throttle valve 63 and the seventh throttle valve 67 respectively play the role of throttling.

[0238] When the refrigeration box module 2 is in the heating mode and the synchronous battery pack heat exchanger 5 is in the cooling mode, the refrigerant refluxes as follows: First, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas. After passing through the compressor 11, the refrigerant is divided into two branches. The first branch is: the refrigerant continues to flow through the fourth throttle valve 64 and flows into the heating box module 3. At this time, the heating box module 3 acts as a condenser, and the refrigerant dissipates heat, thereby heating the items in the heating box body 33. The refrigerant discharged from the outlet of the heating box module 3 is a medium-temperature and high-pressure fluid. Then, the refrigerant passes through the third throttle valve 63, which throttles and cools the refrigerant, turning it into low-temperature and low-pressure wet steam or supercooled liquid. The second branch is: the refrigerant continues to flow through the third on-off valve 73 and the eighth throttle valve 68, and then flows into the battery pack heat exchanger 5. The low-temperature battery pack absorbs the heat of the refrigerant through the battery pack heat exchanger 5, and the temperature rises. After passing through the battery pack heat exchanger 5, the refrigerant is cooled into a medium-temperature and high-pressure fluid. Then, the refrigerant flows to the seventh throttle valve 67, which throttles and cools the refrigerant, turning it into a low-temperature and low-pressure wet steam or supercooled liquid. The refrigerant merges at the outlet of the sixth throttle valve 66 and the outlet of the seventh throttle valve 67. Subsequently, the refrigerant flows into the plate heat exchanger 44, at which time the plate heat exchanger 44 acts as an evaporator, and the refrigerant is heated by the waste heat of the outside environment or the motor 42, completing the process of absorbing heat from the outside environment. The refrigerant discharged from the outlet of the plate heat exchanger 44 is a low-temperature and low-pressure fluid. The refrigerant continues to flow, passing through the first on-off valve 71 and the compressor 11 in sequence, and circulates.

[0239] For example, refer to Fig.33 When the vehicle needs to be heated, the items need to be heated, and the battery pack needs to be heated, the air conditioning module 1 is in the heating mode, the synchronous refrigeration box module 2 is in the heating mode, and the battery pack heat exchanger 5 is in the cooling mode, the sixth throttle valve 66, the seventh throttle valve 67, the eighth throttle valve 68, the third on-off valve 73, the first on-off valve 71, the fourth throttle valve 64 and the third throttle valve 63 are opened, and the second on-off valve 72, the fourth on-off valve 74, the fifth throttle valve 65, the first throttle valve 61 and the second throttle valve 62 are closed. The refrigerant can be controlled to pass through the compressor 11 in sequence, and then branched. The first branch is the refrigerant passing through the second in-vehicle heat exchanger 12 and the sixth throttle valve 66 in sequence. The second branch is the refrigerant passing through the fourth throttle valve 64, the heating box module 3 and the third throttle valve 63 in sequence. The third branch is the refrigerant passing through the third on-off valve 73, the eighth throttle valve 68, the battery pack heat exchanger 5 and the seventh throttle valve 67 in sequence. The refrigerant merges at the outlet of the sixth throttle valve 66, the outlet of the third throttle valve 63 and the outlet of the seventh throttle valve 67. Then, the refrigerant passes through the plate heat exchanger 44 and the first on-off valve 71 in sequence and flows into the compressor 11. The third throttle valve 63, the sixth throttle valve 66 and the seventh throttle valve 67 respectively play the role of throttling.

[0240] When the air conditioning module 1 is in heating mode, the synchronous refrigeration box module 2 is in heating mode and the battery pack heat exchanger 5 is in cooling mode, the refrigerant refluxes as follows: First, the refrigerant passes through the compressor 11, and the refrigerant is compressed by the compressor 11 and discharges high-temperature and high-pressure gas. After passing through the compressor 11, the refrigerant is divided into three branches. The first branch is: the refrigerant enters the second in-vehicle heat exchanger 12. At this time, there is wind passing through the second in-vehicle heat exchanger 12, and the refrigerant dissipates heat. The low-temperature air in the car passes through the second in-vehicle heat exchanger 12 and is heated to high-temperature air to supply the car for heating. The refrigerant discharged from the outlet of the second in-vehicle heat exchanger 12 is a medium-temperature and high-pressure fluid. Next, the refrigerant passes through the sixth throttle valve 66, and the sixth throttle valve 66 throttles and cools down, turning into low-temperature and low-pressure wet steam or supercooled liquid.

[0241] The second branch is: the refrigerant continues to flow through the third on-off valve 73 and the eighth throttle valve 68, and then flows into the battery pack heat exchanger 5. The low-temperature battery pack absorbs the heat of the refrigerant through the battery pack heat exchanger 5, and the temperature rises. The refrigerant is cooled into a medium-temperature and high-pressure fluid after passing through the battery pack heat exchanger 5. Then, the refrigerant flows to the seventh throttle valve 67, which throttles and cools the refrigerant, turning it into low-temperature and low-pressure wet steam or supercooled liquid.

[0242] The third branch is: the refrigerant continues to flow through the fourth throttle valve 64 and flows into the heating box module 3. At this time, the heating box module 3 acts as a condenser, and the refrigerant dissipates heat, thereby heating the items in the heating box body 33. The refrigerant discharged from the outlet of the heating box module 3 is a medium-temperature and high-pressure fluid. Then, the refrigerant passes through the third throttle valve 63, which throttles and cools the refrigerant, turning it into a low-temperature and low-pressure wet steam or supercooled liquid. The refrigerant merges at the outlet of the sixth throttle valve 66, the outlet of the third throttle valve 63, and the outlet of the seventh throttle valve 67. Subsequently, the refrigerant flows into the plate heat exchanger 44. At this time, the plate heat exchanger 44 acts as an evaporator, and the refrigerant is heated by the waste heat of the outside environment or the motor 42, completing the process of absorbing heat from the outside environment. The refrigerant discharged from the outlet of the plate heat exchanger 44 is a low-temperature and low-pressure fluid. The refrigerant continues to flow, passing through the first on-off valve 71 and the compressor 11 in sequence, and circulates.

[0243] Further, refer to Fig.26 The thermal management system 100 further includes a first one-way valve 81 and a second one-way valve 82. The first one-way valve 81 is connected between the seventh throttle valve 67 and the third end of the plate heat exchanger 44. The first one-way valve 81 is configured so that the refrigerant flowing through the battery pack heat exchanger 5 flows unidirectionally to the plate heat exchanger 44. The second one-way valve 82 is connected between the other end of the off-vehicle heat exchanger 13 and the seventh throttle valve 67. The second one-way valve 82 is configured so that the refrigerant flowing through the off-vehicle heat exchanger 13 flows unidirectionally to the battery pack heat exchanger 5.

[0244] For example, in Fig.26In the example, when the refrigerant flows along the third on-off valve 73, it can pass through the first one-way valve 81. When the refrigerant flows along the second one-way valve 82, it can pass through the fourth on-off valve 74. Therefore, according to the use mode of the battery pack heat exchanger 5, the opening and closing of the third on-off valve 73, the fourth on-off valve 74, the first one-way valve 81 and the second one-way valve 82 are controlled to achieve normal use of the battery pack heat exchanger 5. For example, when the battery pack heat exchanger 5 is in the cooling mode, the third on-off valve 73 and the first one-way valve 81 are opened, the fourth on-off valve 74 and the second one-way valve 82 are closed, and after the refrigerant flows out of the compressor 11, it passes through the third on-off valve 73, the eighth throttle valve 68, the battery pack heat exchanger 5, the seventh throttle valve 67 and the first one-way valve 81 in sequence, so that the refrigerant flows in one direction. When the battery pack heat exchanger 5 is in the heating mode, the third on-off valve 73 and the first one-way valve 81 are closed, the fourth on-off valve 74 and the second one-way valve 82 are opened, and the refrigerant flows out of the external heat exchanger 13, and then passes through the second one-way valve 82, the seventh throttle valve 67, the battery pack heat exchanger 5 and the fourth on-off valve 74 in sequence. After the refrigerant flows out of the fourth on-off valve 74, it flows to the inlet of the compressor 11, so that the refrigerant flows in one direction. In addition, the refrigerant can only flow out along the outlet of the first one-way valve 81, or the refrigerant can merge with the outlet of the first one-way valve 81 at least one of the outlets of the third throttle valve 63 and the outlet of the sixth throttle valve 66, thereby further helping to adjust the use mode of the battery pack heat exchanger 5 together with other components in the thermal management system 100, and improving the use flexibility of the thermal management system 100.

[0245] Further, refer to Fig.24 The thermal management system 100 further includes a fifth on-off valve 75, which is connected between the first one-way valve 81 and the third end 443 of the plate heat exchanger 44. Fig.24 In the example, the fifth on-off valve 75 is connected to the outlet of the first one-way valve 81. When the fifth on-off valve 75 is opened, the refrigerant can pass through the plate heat exchanger 44 and absorb heat from the environment outside the vehicle and the motor 42. When the fifth on-off valve 75 is closed, the refrigerant cannot pass through the plate heat exchanger 44, and the plate heat exchanger 44 is used as a flow channel in the motor module 4. With such a configuration, the working state of the plate heat exchanger 44 can be controlled by controlling the fifth on-off valve 75, so that it is convenient to select the working state of the plate heat exchanger 44 according to the actual use situation, thereby improving the use flexibility of the motor module 4 and also improving the applicability of the use of the motor module 4.

[0246] Alternatively, if Fig.12As shown, the thermal management system 100 further includes a gas-liquid separator 9, which is arranged at the inlet of the compressor 11. The refrigerant needs to pass through the gas-liquid separator 9 before entering the compressor 11. When the refrigerant passes through other components, it takes away the refrigerant oil in the above-mentioned other components. The gas-liquid separator 9 can separate the refrigerant from the refrigerant oil, and can also separate the gas and liquid of the refrigerant, so that the refrigerant returning to the compressor 11 is all gaseous refrigerant, and the gas-liquid separator 9 acts as an intermediate storage of the refrigerant gas, thereby ensuring the stable suction of the compressor 11 and avoiding liquid accumulation in the compressor 1111.
