Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a heat exchange module, a thermal management system and a vehicle. Background Art

[0002] With the increase in the number of vehicles, the decreasing of petroleum resources day by day, and the increasing pollution of vehicle exhaust to the air, researching new energy, energy-saving technologies and vehicle integrated thermal management solutions of vehicles has become a trend.

[0003] In related technologies, a blower, an evaporator and a speed regulation module are respectively arranged in an air conditioner box body, and the speed regulation module is arranged at the air outlet of the blower and used for adjusting the rotation speed of the blower. After long-term operation, it is easy to cause the metal oxide semiconductor field effect transistor (MOS transistor) of the speed regulation module to heat up, thereby affecting the entire speed regulation module. If the temperature of the speed regulation module exceeds a certain temperature range, the speed regulation module fails, resulting in the blower not blowing air (i.e., the MOS transistor is broken down or the protection fuse is disconnected), and the maximum wind speed of the blower (i.e., the MOS transistor is broken down and short-circuited).

[0041] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Below, reference is made to Figures 1 - 3 Describe the heat exchange module 100 according to the embodiment of the first aspect of the present utility model.

[0042] As Figure 1 shown, the heat exchange module 100 according to the embodiment of the first aspect of the present utility model includes a plate heat exchanger 1 and a speed regulation module 2 connected into a circulating flow path. The inlet and outlet of the speed regulation module 2 are respectively connected to the first end 11 and the second end 12 of the plate heat exchanger 1. The plate heat exchanger 1 is adapted to be arranged on the refrigerant return path of the thermal management system 200.

[0043] For example, in Figure 1 and Figure 4 examples, the speed regulation module 2 communicates with the plate heat exchanger 1. When the plate heat exchanger 1 is used on the refrigerant return path of the thermal management system 200, when the thermal management system 200 heats up, the coolant (such as water) in the circulating flow path exchanges heat with the refrigerant in the refrigerant return path of the thermal management system 200 at the plate heat exchanger 1. After passing through the plate heat exchanger 1, the temperature of the refrigerant increases, and the temperature of the coolant decreases after passing through the plate heat exchanger 1. Subsequently, the coolant passes through the speed regulation module 2. After the speed regulation module 2 works for a period of time, the temperature of the speed regulation module 2 increases. The coolant exchanges heat with the speed regulation module 2, and the temperature of the speed regulation module 2 decreases. The coolant passes through the plate heat exchanger 1 again to exchange heat with the refrigerant.

[0044] With such a setting, compared with the traditional technology where the speed regulation module is placed between the air outlet of the blower and the evaporator, in this application, the speed regulation module 2 is placed in the circulation flow path of the heat exchange module 100. The position of the speed regulation module 2 has changed. The speed regulation module 2 exchanges heat with the coolant in the circulation flow path, and the coolant cools down the speed regulation module 2, improving the heat dissipation efficiency of the speed regulation module 2, reducing the probability of the speed regulation module 2 malfunctioning, thus extending the service life of the speed regulation module 2 and facilitating the long-term use of the blower. In addition, the heat source modes are waste heat utilization (i.e., utilizing the waste heat of the coolant in the circulation flow path) and compensation (i.e., heating the coolant when the temperature of the coolant in the circulation flow path is too low). The high temperature during the operation of the speed regulation module 2 is effectively used to heat the temperature of the coolant. The heated coolant exchanges heat with the refrigerant in the refrigerant circuit of the thermal management system 200 in the plate heat exchanger 1, reducing the temperature of the coolant and at the same time increasing the temperature of the refrigerant flowing to the compressor 2011 in the thermal management system 200, improving the heating effect of the compressor 2011, effectively improving the situation of liquid accumulation when the superheat of the compressor 2011 is relatively low during operation in a low-temperature environment, and helping to reduce the viscosity of the lubricating oil in the compressor 2011, facilitating the long-term normal use of the compressor 2011, also improving the reliability of the use of the thermal management system 200 and the energy utilization rate of the thermal management system 200. Additionally, the change in the position of the speed regulation module 2 avoids the speed regulation module 2 blocking the air outlet of the blower, increasing the air volume of the blower under the same conditions. Moreover, removing the speed regulation module 2 from the box avoids the high-temperature air of the speed regulation module 2 increasing the temperature when the air flows from the blower to the evaporator, thus reducing the inlet air temperature of the evaporator and facilitating the use of the thermal management system 200. It should be noted that the speed regulation module 2 can be arbitrarily changed according to the spatial layout in the circulation flow path, improving the flexibility of the use of the speed regulation module 2 and facilitating the overall vehicle layout of the vehicle.

[0045] According to the heat exchange module 100 of the present utility model, compared with the traditional technology, the position of the speed regulation module 2 has changed. When the heat management system 200 is in the heating mode, the speed regulation module 2 exchanges heat with the coolant, and the coolant exchanges heat with the refrigerant in the plate heat exchanger 1 to cool down the speed regulation module 2, improving the heat dissipation efficiency of the speed regulation module 2, reducing the probability of the speed regulation module 2 malfunctioning, and facilitating the long-term use of the blower. In addition, the heat source mode is waste heat utilization and compensation, effectively utilizing the high temperature during the operation of the speed regulation module 2, increasing the temperature of the refrigerant flowing to the compressor 2011 in the heat management system 200, improving the heating effect of the compressor 2011, effectively improving the situation of liquid accumulation when the compressor 2011 has a relatively low superheat during operation in a low-temperature environment, and helping to reduce the viscosity of the lubricating oil in the compressor 2011, facilitating the long-term normal use of the compressor 2011, also improving the reliability of the heat management system 200 in use and the energy utilization rate of the heat management system 200. Additionally, it avoids the speed regulation module 2 blocking the air outlet of the blower, increasing the air volume of the blower under the same conditions. Moreover, it avoids the high temperature of the speed regulation module 2 affecting the temperature of the air flowing from the blower to the evaporator, thereby reducing the inlet air temperature of the evaporator.

[0046] According to some embodiments of the present utility model, referring to Figure 1 and Figure 4 , the inlet of the speed regulation module 2 is connected to the first end 11, the outlet of the speed regulation module 2 is connected to the second end 12, and the heat exchange module 100 further includes a high-pressure component 3. One end of the high-pressure component 3 is connected to the outlet of the speed regulation module 2 in a switchable manner, and the other end of the high-pressure component 3 is connected to the second end 12.

[0047] For example, in the examples of Figure 1 and Figure 4 , when the air-conditioning module 201 of the heat management system 200 is in the heating mode, the above-mentioned one end of the high-pressure component 3 is in communication with the outlet of the speed regulation module 2. When the air-conditioning module 201 of the heat management system 200 is in the cooling mode, the above-mentioned one end of the high-pressure component 3 is disconnected from the outlet of the speed regulation module 2.

[0048] With such a setting, when the air-conditioning module 201 is in the heating mode, after the high-pressure component 3 works for a period of time, the temperature of the high-pressure component 3 is relatively high. When the coolant and the refrigerant exchange heat in the circulation flow path, the heat of the speed regulation module 2 and the high-pressure component 3 can be utilized, thereby further increasing the heat of heat exchange, further increasing the temperature of the refrigerant flowing to the compressor 2011, improving the heating effect of the compressor 2011, and also improving the service performance of the compressor 2011. In addition, the temperature of the high-pressure component 3 is effectively reduced, and the heat dissipation efficiency of the high-pressure component 3 is improved, so that the high-pressure component 3 can be used normally for a long time. It should be noted that the high-pressure component 3 includes a motor and an electronic control, etc.

[0049] According to some embodiments of the present utility model, referring to Figure 1 and Figure 5 , the heat exchange module 100 further includes a radiator 4, the radiator 4 is arranged between the outlet of the speed regulation module 2 and the high-pressure component 3, and the inlet of the radiator 4 is connected to the outlet of the speed regulation module 2 in a switchable manner.

[0050] For example, in the examples of Figure 1 and Figure 5 , when the air-conditioning module 201 of the thermal management system 200 is in the heating mode, the above-mentioned one end of the high-pressure component 3 is communicated with the outlet of the speed regulation module 2, and the inlet of the radiator 4 is disconnected from the outlet of the speed regulation module 2, that is, the radiator 4 is not used to dissipate heat from the speed regulation module 2 and the high-pressure component 3, and the coolant sequentially passes through the speed regulation module 2, the high-pressure component 3 and the plate heat exchanger 1, and the coolant exchanges heat with the refrigerant at the plate heat exchanger 1. When the air-conditioning module 201 of the thermal management system 200 is in the cooling mode, the above-mentioned one end of the high-pressure component 3 is disconnected from the outlet of the speed regulation module 2, the inlet of the radiator 4 is communicated with the outlet of the high-pressure module, and the outlet of the radiator 4 is communicated with the above-mentioned one end of the high-pressure component 3, that is, the radiator 4 is not used to dissipate heat from the speed regulation module 2 and the high-pressure component 3, and the coolant sequentially passes through the speed regulation module 2, the radiator 4, the high-pressure component 3 and the plate heat exchanger 1, and the plate heat exchanger 1 only serves as a channel. When the coolant flows through the speed regulation module 2, it exchanges heat with the speed regulation module 2, the temperature of the speed regulation module 2 decreases, and the temperature of the coolant increases. The coolant passes through the radiator 4, and the radiator 4 dissipates heat from the coolant, so that the temperature of the coolant decreases. When the coolant flows through the high-pressure component 3, it exchanges heat with the high-pressure component 3, the temperature of the high-pressure component 3 decreases, and the temperature of the coolant increases. Thus, the radiator 4 dissipates heat from the coolant to reduce the temperatures of the speed regulation module 2 and the high-pressure component 3, avoiding damage to the speed regulation module 2 and the high-pressure component 3 at high temperatures, thereby prolonging the normal use of the speed regulation module 2 and the high-pressure component 3 for a long time and improving the service performance of the heat exchange module 100. In addition, the heat exchange module 100 has a simple structure and is easy to assemble, improving the production efficiency of the heat exchange module 100.

[0051] Further, referring to Figure 1 , Figure 4 and Figure 5 , the heat exchange module 100 further includes a switching member 5, the switching member 5 has a first interface 51, a second interface 52 and a third interface 53, the first interface 51 is selectively communicated with one of the second interface 52 and the third interface 53, the first interface 51 is connected to the outlet of the speed regulation module 2, the second interface 52 is connected to the inlet of the radiator 4, and the third interface 53 is connected to the high-pressure component 3.

[0052] For example, in Figure 1 , Figure 4 and Figure 5In the example, when the air conditioning module 201 of the thermal management system 200 is in the heating mode, the first interface 51 is disconnected from the second interface 52, and the first interface 51 is connected to the third interface 53, that is, the speed regulation module 2 is disconnected from the radiator 4 and the speed regulation module 2 is connected to the high-voltage component 3. When the air conditioning module 201 of the thermal management system 200 is in the cooling mode, the first interface 51 is connected to the second interface 52, and the first interface 51 is disconnected from the third interface 53, that is, the radiator 4 is located between the speed regulation module 2 and the high-voltage component 3. Thus, through the switching member 5, it is possible to control the speed regulation module 2 to be directly connected to either the radiator 4 or the high-voltage component 3, facilitating heat dissipation of the speed regulation module 2 and the high-voltage component 3 in different operating modes of the air conditioning assembly, effectively ensuring heat dissipation of the speed regulation module 2 and the high-voltage component 3, and thereby extending the service life of the heat exchange module 100. It should be noted that the switching member 5 can be a three-way valve.

[0053] According to some embodiments of the present invention, referring to Figure 1 , the heat exchange module 100 further includes a pump 6, and the pump 6 is provided between the other end of the high-voltage component 3 and the second end 12 of the plate heat exchanger 1. With this arrangement, the pump 6 provides power for the flow of the coolant in the circulation flow path, thereby ensuring that the coolant can pass through multiple components (such as the speed regulation module 2, the radiator 4, and the high-voltage component 3) to exchange heat, enabling the above-mentioned multiple components to be used normally for a long time and improving the performance of the heat exchange module 100.

[0054] According to some embodiments of the present invention, referring to Figure 4 , the flow direction of the refrigerant in the circulation flow path in the plate heat exchanger 1 is opposite to the flow direction of the refrigerant in the refrigerant circuit in the plate heat exchanger 1. With this arrangement, it effectively ensures sufficient contact between the coolant and the refrigerant when heat exchange occurs between the coolant and the refrigerant in the plate heat exchanger 1, improves the heat exchange effect, thereby improving the utilization rate of heat and the performance of the circulation flow path.

[0055] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 , the speed regulation module 2 includes a main body 21 and a housing 22. The housing 22 is provided on the outer peripheral side of the main body 21. An inlet pipeline 221 and an outlet pipeline 222 are provided on the housing 22. The inlet pipeline 221 is connected to the first end 11, and the outlet pipeline 222 is connected to the second end 12. For example, in Figure 2 and Figure 3In the example, the inlet pipeline 221 and the outlet pipeline 222 are respectively located on opposite sides of the housing 22. The coolant can enter the housing 22 through the inlet pipeline 221 and then flow out through the outlet pipeline 222. With such an arrangement, it is convenient for the main body 21 to contact the coolant, improving the cooling rate of the speed regulation module 2, further preventing the speed regulation module 2 from being damaged, and further extending the service life of the speed regulation module 2. In addition, the speed regulation module 2 has a simple structure, facilitating the movement of the position of the speed regulation module 2 and improving the flexibility of use of the speed regulation module 2.

[0056] According to the heat management system 200 of the second aspect embodiment of the present invention, referring to Figure 1 and Figure 4 , it includes an air conditioning module 201. The air conditioning module 201 includes a compressor 2011, a first in-vehicle heat exchanger 2012, and a plate heat exchanger 1 that are connected to form a refrigerant circuit. The plate heat exchanger 1 is the plate heat exchanger 1 of the heat exchange module 100 according to the above first aspect embodiment of the present invention. One end of the first in-vehicle heat exchanger 2012 is connected to the outlet of the compressor 2011, and the other end of the first in-vehicle heat exchanger 2012 is connected to the third end 13 of the plate heat exchanger 1 in a switchable manner. The fourth end 14 of the plate heat exchanger 1 is connected to the inlet of the compressor 2011.

[0057] For example, in the examples of Figure 1 and Figure 4 , the inlet of the first in-vehicle heat exchanger 2012 is in communication with the outlet of the compressor 2011. When the air conditioning module 201 is in the heating mode, the outlet of the first in-vehicle heat exchanger 2012 is in communication with the third end 13 of the plate heat exchanger 1. When the air conditioning module 201 is in the cooling mode, the outlet of the first in-vehicle heat exchanger 2012 is disconnected from the third end 13 of the plate heat exchanger 1.

[0058] When the air conditioning module 201 is in the heating mode, the compressor 2011, the first in-vehicle heat exchanger 2012, and the plate heat exchanger 1 are arranged in series with each other. In the heat exchange module 100, the speed regulation module 2, the first interface 51 of the switching member 5, the third interface 53 of the switching member 5, the high-pressure component 3, the pump 6, and the plate heat exchanger 1 are arranged in series with each other.

[0059] When the air - conditioning module 201 is in the heating mode, when the refrigerant passes through the first in - vehicle heat exchanger 2012, there is air passing through the first in - vehicle heat exchanger 2012. The refrigerant exchanges heat with the low - temperature air in the vehicle while flowing through the first in - vehicle heat exchanger 2012, and the refrigerant releases heat to the low - temperature air, raising the temperature of the air in the vehicle, thus realizing the heating mode of the air - conditioning module 201. The refrigerant exchanges heat with the coolant in the plate - type heat exchanger 1 and absorbs heat. With such a setting, the refrigerant utilizes the heat of the speed - regulating module 2 and the high - pressure component 3 itself through the coolant and the plate - type heat exchanger 1, thereby improving the energy utilization rate and the reliability of use of the thermal management system 200. In addition, when the refrigerant flows through the first in - vehicle heat exchanger 2012, it exchanges heat with the air in the vehicle to raise the temperature of the air in the vehicle, realizing the heating mode of the air - conditioning module 201. Thus, when the temperature in the vehicle is relatively low, the heating mode of the air - conditioning module 201 can be turned on to raise the temperature in the vehicle, improving the comfort of the users in the vehicle.

[0060] According to some embodiments of the present utility model, with reference to Figure 1 and Figure 4 , the air - conditioning module 201 further includes a first on - off valve 202 and a second on - off valve 203. The first on - off valve 202 is arranged between the third end 13 of the plate - type heat exchanger 1 and the first in - vehicle heat exchanger 2012, and the second on - off valve 203 is arranged between the fourth end 14 of the plate - type heat exchanger 1 and the inlet of the compressor 2011.

[0061] For example, in the examples of Figure 1 and Figure 4 , the inlet end of the first on - off valve 202 is connected to the outlet end of the first in - vehicle heat exchanger 2012, and the outlet end of the first on - off valve 202 is connected to the third end 13 of the plate - type heat exchanger 1. The inlet end of the second on - off valve 203 is connected to the fourth end 14 of the plate - type heat exchanger 1, and the outlet end of the second on - off valve 203 is connected to the inlet of the compressor 2011. For example, the first on - off valve 202 and the second on - off valve 203 can be solenoid valves. However, it is not limited thereto.

[0062] It should be noted that, in the examples of Figure 4 , the dotted line is the flow route of the refrigerant, and the direction indicated by the arrow A is the flow direction of the refrigerant. The dotted line is the flow path of the coolant, and the direction indicated by the arrow B is the flow path of the coolant.

[0063] For example, with reference to Figure 4 , when heating is required in the vehicle, the air - conditioning module 201 is in the heating mode. By opening the first on - off valve 202 and the second on - off valve 203, it can control the refrigerant to sequentially pass through the compressor 2011, the first in - vehicle heat exchanger 2012, the first on - off valve 202, the plate - type heat exchanger 1, and then return to the compressor 2011 through the second on - off valve 203. The compressor 2011 performs PID control according to the deviation between the target channel temperature and the actual channel temperature.

[0064] When the air conditioner module 201 is in heating mode, the refrigerant reflux is as follows: First, the refrigerant passes through the compressor 2011. After being compressed by the compressor 2011, the refrigerant is discharged as a high-temperature and high-pressure gas. Then, the refrigerant enters the first in-vehicle heat exchanger 2012. At this time, there is air passing through the first in-vehicle heat exchanger 2012, and the refrigerant dissipates heat. The low-temperature air inside the vehicle passes through the first in-vehicle heat exchanger 2012 and is heated into high-temperature air to supply heating to the vehicle interior. The refrigerant discharged from the outlet of the first in-vehicle heat exchanger 2012 is a medium-temperature and high-pressure fluid. Next, the refrigerant passes through the first on-off valve 202. Subsequently, the refrigerant passes through the plate heat exchanger 1. The plate heat exchanger 1 is an evaporator, and the first in-vehicle heat exchanger 2012 is a condenser. The refrigerant is heated by the coolant in the plate heat exchanger 1, absorbs heat from the plate heat exchanger 1, and the temperature of the refrigerant discharged from the outlet of the vehicle exterior heat exchanger 204 increases. Subsequently, the refrigerant continues to flow into the compressor 2011 for cyclic flow.

[0065] When the air conditioner module 201 is in heating mode, the circulation flow path of the coolant in the heat exchange module 100 is as follows: The coolant sequentially passes through the speed regulation module 2 and the high-pressure component 3, and exchanges heat with the speed regulation module 2 and the high-pressure component 3, and the temperature of the coolant increases. Then, the coolant passes through the pump 6. Next, the coolant enters the plate heat exchanger 1 from the fourth end 14. The coolant exchanges heat with the refrigerant, the temperature of the coolant decreases, and the temperature of the refrigerant increases. Subsequently, the coolant flows out from the first end 11 of the plate heat exchanger 1 and continues to flow into the speed regulation module 2 for cyclic flow and heat exchange.

[0066] With such a setting, through the cooperation of the first on-off valve 202 and the second on-off valve 203, it is possible to control whether the heating mode of the air conditioner module 201 is turned on, thereby realizing the heating of the vehicle interior by the air conditioner module 201. When used in winter, the comfort of the user is improved, and the user's needs are also met. Moreover, the temperatures of the speed regulation module 2 and the high-pressure component 3 are also utilized, improving the energy utilization rate.

[0067] According to some embodiments of the present invention, with reference to Figure 1 and Figure 5 , the thermal management system 200 further includes a vehicle exterior heat exchanger 204 and a second in-vehicle heat exchanger 205. One end of the vehicle exterior heat exchanger 204 is connectable and disconnectable to the other end of the first in-vehicle heat exchanger 2012, and the second in-vehicle heat exchanger 205 is provided between the other end of the vehicle exterior heat exchanger 204 and the inlet of the compressor 2011.

[0068] For example, in Figure 1 and Figure 5In the example, when the air conditioning module 201 is in the heating mode, the inlet end of the outdoor heat exchanger 204 is disconnected from the outlet of the first in-vehicle heat exchanger 2012. When the air conditioning module 201 is in the cooling mode, the inlet end of the outdoor heat exchanger 204 (i.e., the aforementioned one end of the outdoor heat exchanger 204) is connected to the outlet of the first in-vehicle heat exchanger 2012, the outlet end of the outdoor heat exchanger 204 (i.e., the aforementioned other end of the outdoor heat exchanger 204) is connected to the inlet end of the second in-vehicle heat exchanger 205, and the outlet end of the second in-vehicle heat exchanger 205 is connected to the inlet of the compressor 2011. The compressor 2011, the first in-vehicle heat exchanger 2012, the outdoor heat exchanger 204, and the second in-vehicle heat exchanger 205 are arranged in series with each other, and the first in-vehicle heat exchanger 2012 serves only as a passage. In the heat exchange module 100, the speed regulation module 2, the first interface 51 of the on-off member 5, the second interface 52 of the on-off member 5, the heat exchanger, the high-pressure component 3, the pump 6, and the plate heat exchanger 1 are arranged in series with each other, and the plate heat exchanger 1 serves only as a passage.

[0069] When the air conditioning module 201 is in the cooling mode, the refrigerant flowing out from the outlet of the compressor 2011 passes through the first in-vehicle heat exchanger 2012. Then, when the refrigerant flows into the outdoor heat exchanger 204, the outdoor heat exchanger 204 functions as a condenser, and the refrigerant exchanges heat with the outdoor environment, and the refrigerant releases heat. The second in-vehicle heat exchanger 205 functions as an evaporator, and the refrigerant absorbs the heat from the high-temperature air inside the vehicle. When the refrigerant flows through the second in-vehicle heat exchanger 205, it exchanges heat with the air inside the vehicle to cool the air inside the vehicle, realizing the cooling mode of the air conditioning module 201. Thus, when the temperature inside the vehicle is relatively high, the cooling mode of the air conditioning module 201 can be turned on to cool the inside of the vehicle, improving the comfort of the users inside the vehicle. Moreover, after the radiator 4 cools the coolant, the speed regulation module 2 and the high-pressure component 3 can be cooled by exchanging heat with the coolant, avoiding damage to the speed regulation module 2 and the high-pressure component 3 and extending the service life of the speed regulation module 2 and the high-pressure component 3.

[0070] According to some embodiments of the present invention, with reference to Figure 1 and Figure 5 , the thermal management system 200 further includes a third on-off valve 206, and the third on-off valve 206 is provided between one end of the outdoor heat exchanger 204 and the other end of the first in-vehicle heat exchanger 2012. For example, in the examples of Figure 1 and Figure 5 , the outlet of the third on-off valve 206 is connected to the inlet end of the outdoor heat exchanger 204, and the inlet of the third on-off valve 206 is connected to the outlet end of the first in-vehicle heat exchanger 2012. For example, the third on-off valve 206 is a solenoid valve.

[0071] With such a setting, by opening and closing the third on-off valve 206, it is possible to control whether the refrigerant flows to the outside vehicle heat exchanger 204, thereby controlling whether the air conditioning module 201 is in a cooling or heating mode. When the third on-off valve 206 is open, the air conditioning module 201 is in the cooling mode. When the third on-off valve 206 is closed, the air conditioner is in the heating mode, thereby improving the applicability flexibility of the air conditioning mode, facilitating setting according to actual application conditions, and enhancing the user experience.

[0072] According to some embodiments of the present invention, referring to Figure 1 and Figure 5 , the thermal management system 200 further includes a first throttle valve 207 and a fourth on-off valve 208. The first throttle valve 207 is connected between one end of the first in-vehicle heat exchanger 2012 and the outside vehicle heat exchanger 204. The fourth on-off valve 208 is connected in parallel with the first throttle valve 207. The other end of the first in-vehicle heat exchanger 2012 communicates with at least one of the first throttle valve 207 and the fourth on-off valve 208.

[0073] For example, in the examples of Figure 1 and Figure 5 , the inlet end of the first throttle valve 207 is connected to the outlet end of the first in-vehicle heat exchanger 2012, the outlet end of the first throttle valve 207 is connected to the inlet end of the outside vehicle heat exchanger 204 (i.e., one end of the above-mentioned outside vehicle heat exchanger 204), the inlet end of the fourth on-off valve 208 is connected to the outlet end of the first in-vehicle heat exchanger 2012, and the outlet end of the fourth on-off valve 208 is connected to the inlet end of the outside vehicle heat exchanger 204. For example, the first throttle valve 207 can be an electronic expansion valve, and the fourth on-off valve 208 can be an electromagnetic valve. However, it is not limited thereto.

[0074] After the air conditioning module 201 receives a heating work request, the refrigerant flow path for heating of the air conditioning module 201 in the thermal management system 200 is opened, that is, the first throttle valve 207 is opened and the fourth on-off valve 208 is closed. After the air conditioning module 201 receives a cooling work request, the refrigerant flow path for heating of the air conditioning module 201 in the thermal management system 200 is opened, that is, the first throttle valve 207 is closed and the fourth on-off valve 208 is opened.

[0075] With such a setting, by the cooperation of the first throttle valve 207 and the fourth on-off valve 208, it is possible to control the air conditioning module 201 to turn on the heating mode or the cooling mode, thereby realizing heating or cooling of the vehicle interior by the air conditioning module 201, facilitating use in winter or summer, improving the user comfort, and also meeting the user's needs.

[0076] It should be noted that in the examples of Figure 5 , the dotted line is the flow route of the refrigerant, and the direction indicated by the arrow C is the flow direction of the refrigerant. The dotted line is the flow path of the coolant, and the direction indicated by the arrow D is the flow path of the coolant.

[0077] For example, referring to Figure 5 , when the vehicle interior needs to be cooled, the air conditioning module 201 is in the cooling mode. The fourth on-off valve 208 and the third on-off valve 206 are opened, and the first throttle valve 207, the first on-off valve 202, and the second on-off valve 203 are closed.

[0078] When the air conditioning module 201 is in the cooling mode, the refrigerant flows back as follows: First, the refrigerant passes through the compressor 2011. After being compressed by the compressor 2011, the refrigerant discharges high-temperature and high-pressure gas. Then, the refrigerant enters the first in-vehicle heat exchanger 2012. At this time, there is no air passing through the first in-vehicle heat exchanger 2012, and the first in-vehicle heat exchanger 2012 only serves as a flow channel. The refrigerant discharged from the outlet of the first in-vehicle heat exchanger 2012 is still high-temperature and high-pressure gas. The refrigerant continues to flow and passes through the fourth on-off valve 208 and the third on-off valve 206 in sequence. Subsequently, the refrigerant passes through the out-of-vehicle heat exchanger 204. The refrigerant exchanges heat with the out-of-vehicle environment through the out-of-vehicle heat exchanger 204, and the refrigerant releases heat. The refrigerant discharged from the outlet of the out-of-vehicle heat exchanger 204 is medium-temperature and high-pressure fluid (it should be noted that the fluid can be liquid or gas, which is determined by the temperature of the out-of-vehicle environment).

[0079] Next, the refrigerant continues to flow into the second in-vehicle heat exchanger 205. At this time, the high-temperature air in the vehicle passes through the second in-vehicle heat exchanger 205. The second in-vehicle heat exchanger 205 functions as an evaporator. The refrigerant absorbs heat, and the high-temperature air is cooled to low-temperature air for cooling the vehicle interior. The temperature of the refrigerant discharged from the outlet of the second in-vehicle heat exchanger 205 increases. The refrigerant continues to flow into the compressor 2011 and circulates.

[0080] When the air conditioning module 201 is cooling, the circulation flow path of the coolant in the heat exchange module 100 is as follows: The coolant passes through the speed regulation module 2 and absorbs the temperature in the speed regulation module 2, and the temperature of the coolant increases. Then, the coolant flows to the heat exchanger and exchanges heat with the heat exchanger, and the temperature of the coolant decreases. Next, the coolant continues to flow into the high-pressure component 3 and absorbs the temperature in the high-pressure component 3, and the temperature of the coolant increases. The coolant continues to flow, enters the plate heat exchanger 1 from the second end 12 of the plate heat exchanger 1, and the plate heat exchanger 1 only serves as a channel. Subsequently, the coolant flows out from the first end 11 of the plate heat exchanger 1 and continues to flow into the speed regulation module 2 for circulating and heat exchange.

[0081] With such a configuration, the first throttle valve 207 and the fourth on-off valve 208 can be used to control whether the cooling mode of the air conditioning module 201 is turned on, thereby realizing the cooling of the interior of the vehicle by the air conditioning module 201. When used in summer, this improves the user's comfort and meets the user's needs. Moreover, the speed regulating module 2 and the high-voltage component 3 are cooled by heat exchange between the radiator 4 and the coolant, thereby extending the service life of the speed regulating module 2 and the high-voltage component 3. When the air conditioning module 201 is heating, the first throttle valve 207 is controlled according to the exhaust temperature of the compressor 211, and the cold and warm air doors are set to full warm by default.

[0082] Optionally, refer to Figure 5 The thermal management system 200 further includes a second throttle valve 209 and a gas-liquid separator 2013. The second throttle valve 209 is located between the external heat exchanger 204 and the second internal heat exchanger 205. The inlet of the second throttle valve 209 is connected to the outlet end of the external heat exchanger 204, and the outlet of the second throttle valve 209 is connected to the inlet of the second internal heat exchanger 205. The gas-liquid separator 2013 is arranged at the inlet of the compressor 2011. The refrigerant needs to pass through the gas-liquid separator 2013 before entering the compressor 2011. For example, the second throttle valve 209 is an electronic expansion valve. When the air conditioning module 201 is in the heating mode, the second throttle valve 209 is closed. When the air conditioning module 201 is in the cooling mode, the second throttle valve 209 is opened.

[0083] With such arrangement, after the refrigerant flows out from the external heat exchanger 204, the refrigerant can have a throttling effect on the refrigerant, further reducing the temperature of the refrigerant. When the refrigerant flows into the second internal heat exchanger 205 and exchanges heat with the temperature inside the vehicle, the refrigerant can effectively absorb heat, thereby improving the refrigeration effect of the air conditioning module 201 and improving the comfort of the user. In addition, when the refrigerant passes through other components, the refrigerant oil in the above-mentioned other components is taken away. The gas-liquid separator 2013 can separate the refrigerant from the refrigerant oil, and can also separate the gas and liquid of the refrigerant, so that the refrigerant returned to the compressor 2011 is a gaseous refrigerant, and the gas-liquid separator 2013 acts as an intermediate storage of the refrigerant gas, thereby ensuring the stable suction of the compressor 2011 and avoiding the phenomenon of liquid accumulation in the compressor 2011. Among them, when the air conditioning module 201 is refrigerating, the second throttle valve 209 is controlled according to the superheat degree of the outlet of the second external heat exchanger 204, and the cold and warm air door is set to full cold by default. The heat exchange module 100 is suitable for existing heat pump vehicles and hybrid vehicles.
