DETAILED DESCRIPTION

[0050] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0051] In the present disclosure, unless otherwise stated, the directional words used, such as "upstream, downstream", are generally defined based on the refrigerant flow direction. This is only for the convenience of describing the present disclosure and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, and a specific orientation structure and operation, and therefore cannot be understood as a limitation of the present disclosure. "Inside, outside" refers to the inside and outside of the contour of the corresponding component. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0052] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0053] As a first aspect of the present disclosure, Figures 1 to 12 As shown, the present disclosure provides a vehicle thermal management system, including a compressor 1, a vehicle refrigerator 2, a heat exchange module 3 and a refrigerator expansion valve 4, and the vehicle refrigerator 2 includes a refrigerator heat exchanger 21 for exchanging heat with the article storage space of the vehicle refrigerator 2.

[0054] The outlet of the compressor 1 is connected to the first port of the refrigerator heat exchanger 21 and the inlet of the heat exchange module 3, and the outlet of the compressor 1 can be selectively connected or cut off with the first port of the refrigerator heat exchanger 21 and selectively connected or cut off with the inlet of the heat exchange module 3. The second port of the refrigerator heat exchanger 21 is connected to the first port of the refrigerator expansion valve 4, and the second port of the refrigerator expansion valve 4 can be selectively connected to the inlet of the heat exchange module 3 or the outlet of the heat exchange module 3. The inlet of the compressor 1 can be selectively connected to the first port of the refrigerator heat exchanger 21 or the outlet of the heat exchange module 3.

[0055] According to the vehicle thermal management system provided by the present disclosure, by controlling the conduction between the outlet of the compressor 1 and the first port of the refrigerator heat exchanger 21 or the inlet of the heat exchange module 3, the conduction between the second port of the refrigerator expansion valve 4 and the inlet of the heat exchange module 3 or the outlet of the heat exchange module 3, and the conduction between the inlet of the compressor 1 and the first port of the refrigerator heat exchanger 21 or the outlet of the heat exchange module 3, the vehicle thermal management system can have a cooling mode for the vehicle refrigerator 2 and a heating mode for the vehicle refrigerator 2.

[0056] In the cooling mode of the vehicle refrigerator 2, if Figure 7As shown, the outlet of the compressor 1 can be connected to the inlet of the heat exchange module 3, the outlet of the compressor 1 can be cut off from the first port of the refrigerator heat exchanger 21 (that is, the outlet of the compressor 1 can be disconnected from the first port of the refrigerator heat exchanger 21), the second port of the refrigerator expansion valve 4 can be connected to the outlet of the heat exchange module 3, the first port of the refrigerator expansion valve 4 is connected to the second port of the refrigerator heat exchanger 21, and the first port of the refrigerator heat exchanger 21 is connected to the inlet of the compressor 1, so that the compressor 1, the heat exchange module 3, the refrigerator expansion valve 4, and the refrigerator heat exchanger 21 are connected in series in sequence to form a loop. The high-temperature and high-pressure gaseous refrigerant discharged by the compressor 1 flows into the heat exchange module 3, and the refrigerant can release heat in the heat exchange module 3. The refrigerant flowing out of the outlet of the heat exchange module 3 becomes a low-temperature and low-pressure liquid refrigerant after throttling and reducing the pressure through the refrigerator expansion valve 4. The low-temperature and low-pressure liquid refrigerant flows into the refrigerator heat exchanger 21, absorbs the heat of the article storage space in the refrigerator heat exchanger 21, and reduces the temperature in the article storage space, so as to realize the refrigeration or freezing function of the vehicle refrigerator. In the cooling mode of the vehicle-mounted refrigerator 2, the refrigerator heat exchanger 21 functions as an evaporator.

[0057] In the heating mode of the car refrigerator 2, if Figure 8 As shown, the outlet of the compressor 1 can be connected to the first port of the refrigerator heat exchanger 21, the outlet of the compressor 1 can be cut off from the inlet of the heat exchange module 3 (that is, the outlet of the compressor 1 is not connected to the inlet of the heat exchange module 3), the second port of the refrigerator heat exchanger 21 is connected to the first port of the refrigerator expansion valve 4, the second port of the refrigerator expansion valve 4 is connected to the inlet of the heat exchange module 3, and the outlet of the heat exchange module 3 is connected to the inlet of the compressor 1, so that the compressor 1, the refrigerator heat exchanger 21, the refrigerator expansion valve 4, and the heat exchange module 3 are connected in series in sequence to form a loop. The high-temperature and high-pressure gaseous refrigerant discharged from the compressor 1 flows into the refrigerator heat exchanger 21, and the refrigerant releases heat to the item storage space in the refrigerator heat exchanger 21, thereby increasing the temperature in the item storage space, so that the item storage space can be used to keep warm or heat items. The refrigerant after releasing heat flowing out of the second port of the refrigerator heat exchanger 21 is throttled and depressurized by the refrigerator expansion valve 4 and becomes a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant flows into the heat exchange module 3 and absorbs heat in the heat exchange module 3. The outlet of the heat exchange module 3 flows out a low-temperature and low-pressure gaseous refrigerant, which eventually returns to the compressor 1. In the heating mode of the vehicle refrigerator 2, the refrigerator heat exchanger 21 is used as a condenser.

[0058] Through the above technical scheme, by controlling the conduction relationship between the outlet of the compressor 1 and the first port of the refrigerator heat exchanger 21 and the inlet of the heat exchange module 3, the conduction relationship between the second port of the refrigerator expansion valve 4 and the inlet of the heat exchange module 3 and the outlet of the heat exchange module 3, and the conduction relationship between the inlet of the compressor 1 and the first port of the refrigerator heat exchanger 21 and the outlet of the heat exchange module 3, the high-temperature and high-pressure gaseous refrigerant flowing out of the compressor 1 can release heat through the heat exchange module 3 and then absorb heat in the article storage space in the refrigerator heat exchanger 21, thereby realizing the refrigeration of the vehicle refrigerator 2, or the high-temperature and high-pressure gaseous refrigerant flowing out of the compressor 1 can enter the refrigerator heat exchanger 21 and release heat to the article storage space, thereby realizing the heating of the vehicle refrigerator 2, thereby making the vehicle refrigerator 2 provided by the present disclosure have both refrigeration function and heating function, and the temperature adjustment range in the article storage space is wide and the functions are rich, which can enhance the user's car experience.

[0059] In order to increase the storage space of the vehicle, optionally, Figure 4 As shown, there can be multiple vehicle refrigerators 2, each of which includes a refrigerator heat exchanger 21, and the multiple refrigerator heat exchangers 21 are connected in parallel. There are multiple refrigerator expansion valves 4, and the multiple refrigerator expansion valves 4 correspond one-to-one to the multiple refrigerator heat exchangers 21. The outlet of the compressor 1 can be selectively connected or cut off with the first port of any refrigerator heat exchanger 21, and the second port of each refrigerator expansion valve 4 can be selectively connected to the inlet of the heat exchange module 3 or the outlet of the heat exchange module 3. The inlet of the compressor 1 can be selectively connected to the first port of any refrigerator heat exchanger 21 or the outlet of the heat exchange module 3. That is, the outlet of the compressor 1 can be connected to the first port of any refrigerator heat exchanger 21, and the second port of any refrigerator expansion valve 4 can be connected to the inlet of the heat exchange module 3, so that one of the multiple vehicle refrigerators 2 can achieve heating or multiple vehicle refrigerators 2 can achieve heating at the same time; the second port of any refrigerator expansion valve 4 can be connected to the outlet of the heat exchange module 3, and the inlet of the compressor 1 can be connected to the first port of any refrigerator heat exchanger 21, so that one of the multiple vehicle refrigerators 2 can achieve cooling or multiple vehicle refrigerators 2 can achieve cooling at the same time. The provision of multiple vehicle refrigerators 2 can increase the storage space of the vehicle and improve the user's vehicle experience.

[0060] like Figure 4 As shown, a ninth switch valve 29 can be correspondingly provided at the first port of each refrigerator heat exchanger 21. By controlling the conduction or cutoff of the corresponding ninth switch valve 29, it can be controlled whether the refrigerant flowing out of the compressor 1 flows into the refrigerator heat exchanger 21 corresponding to the ninth switch valve 29, so that the outlet of the compressor 1 mentioned above can be connected with the first port of any refrigerator heat exchanger 21, so that multiple refrigerator heat exchangers 21 can heat at the same time, or only partially heat.

[0061] The refrigerator expansion valve 4 can also control the on-off of the refrigerant flow path where the refrigerator heat exchanger 21 is located, that is, the refrigerant flowing out of the outlet of the heat exchange module 3 can enter the refrigerator heat exchanger 21 or not, so as to realize the conduction between any refrigerator expansion valve 4 and the outlet of the heat exchange module 3 mentioned above, so that multiple refrigerator heat exchangers 21 can be refrigerated at the same time, or only partially refrigerated. In addition, the refrigerator expansion valve 4 can also adjust the evaporation pressure and evaporation temperature of the refrigerant entering its corresponding refrigerator heat exchanger 21, so that the item storage space of multiple vehicle refrigerators 2 can have different refrigeration temperatures or freezing temperatures. Multiple vehicle refrigerators 2 can be arranged at different positions of the vehicle. For example, multiple vehicle refrigerators 2 can be arranged in the front and rear positions of the vehicle passenger compartment respectively, so as to meet the use needs of passengers sitting in different seats.

[0062] Alternatively, if Figure 6 As shown, the vehicle refrigerator 2 further includes a heating element 28, which is used to heat the air in the item storage space; or, the vehicle refrigerator 2 further includes a cooling element, which is used to cool the air in the item storage space.

[0063] The heating element 28 is used to heat the air in the item storage space, or the cooling element is used to cool the air in the item storage space. On the one hand, it can serve as a supplement to cooling or heating when the heating or cooling effect of the refrigerator heat exchanger 21 is not good, or when the user needs rapid cooling or rapid heating, thereby further improving the heating or cooling effect of the vehicle refrigerator 2; on the other hand, it can also serve as a backup temperature control device when the refrigerator heat exchanger 21 fails, maintaining the temperature of the vehicle refrigerator 2 within a preset temperature range, thereby ensuring that the storage temperature of the items in the vehicle refrigerator 2 meets user needs.

[0064] For the embodiment in which there are multiple vehicle refrigerators 2, one or part of the vehicle refrigerators 2 can also be made to achieve cooling through the refrigerator heat exchanger 21, and another or part of the vehicle refrigerators 2 can achieve heating through the heating element 28; or, one or part of the vehicle refrigerators 2 can achieve heating through the refrigerator heat exchanger 21, and another or part of the vehicle refrigerators 2 can achieve cooling through the cooling element. In this way, one or part of the vehicle refrigerators 2 can meet the user's refrigeration or freezing needs, and another or part of the vehicle refrigerators 2 can meet the user's insulation or heating needs, further improving the user's car experience.

[0065] In order to improve the heat exchange effect between the refrigerator heat exchanger 21 and the air in the article storage space, optionally, as Figure 6As shown, the refrigerator heat exchanger 21 includes a heat exchange tube 211 and a heat exchange shell 212. The inner surface of the heat exchange shell 212 defines an article storage space. The heat exchange tube 211 is used for allowing refrigerant to flow through. The heat exchange tube 211 is in thermal contact with the outer surface of the heat exchange shell 212 so that the refrigerant in the heat exchange tube 211 can directly exchange heat with the air in the article storage space through the heat exchange shell 212.

[0066] The heat exchange tube 211 is in thermal contact with the outer surface of the heat exchange shell 212, and the inner surface of the heat exchange shell 212 defines an article storage space. The heat exchange shell 212 can directly contact the air in the article storage space, so that the cold or heat of the refrigerant in the heat exchange tube 211 can be directly transferred to the heat exchange shell 212 through the heat exchange tube 211, and heat is directly exchanged with the air in the article storage space through the heat exchange shell 212, thereby reducing the loss of cold or heat in the conduction process and improving the cooling or heating efficiency of the vehicle refrigerator 2.

[0067] Optionally, the thermal conductivity of the heat exchange housing 212 may be 201W / mk-237W / mk. The material under this coefficient has good thermal conductivity and can meet the heat exchange requirements of the heat exchange tube 211 exchanging heat with the air in the article storage space through the heat exchange housing 212.

[0068] The present disclosure does not limit the specific material of the heat exchange shell 212. For example, the material of the heat exchange shell 212 may be aluminum or copper.

[0069] For the above-mentioned embodiment in which the vehicle refrigerator 2 includes a heating element 28, the heating element 28 may be any appropriate heating structure, such as a heating wire, a heating film, etc. Figure 6 As shown, in one embodiment provided by the present disclosure, the heating element 28 may include a heating film, which covers the outer surface of the heat exchange shell 212 and / or the side of the heat exchange tube 211 facing away from the heat exchange shell 212.

[0070] For the above-mentioned embodiment in which the vehicle refrigerator 2 includes a cooling element, the cooling element may include a semiconductor cooling sheet, which covers the outer surface of the heat exchange shell 212 and / or the side of the heat exchange tube 211 facing away from the heat exchange shell 212.

[0071] The heating film or semiconductor cooling sheet covering the outer surface of the heat exchange shell 212 can directly exchange heat with the heat exchange shell 212, and exchange heat with the air in the object storage space through the heat exchange shell 212, thereby reducing heat loss during heating or cooling.

[0072] In order to speed up the air flow in the article storage space, optionally, Figure 2As shown, the vehicle refrigerator 2 further includes a housing 27 and a fan 25, the housing 27 defines an article storage space, and the fan 25 is installed on the housing 27, and the fan 25 is used to accelerate the flow of air in the article storage space. For example, the fan 25 is used to generate an airflow that can exchange heat with the refrigerant in the refrigerator heat exchanger 21 and enter the article storage space. The fan 25 can accelerate the fluidity between the air near the refrigerator heat exchanger 21 and the air in the article storage space, thereby improving the heat exchange efficiency between the refrigerator heat exchanger 21 and the air in the article storage space, and improving the heating or cooling speed of the vehicle refrigerator 2. It can be understood that when the air in the article storage space is heated by the heating element 28 or the cooling element is used to cool the air in the article storage space, the fan 25 can also accelerate the fluidity between the air near the heating element 28 or the cooling element and the air in the article storage space, thereby improving the heat exchange efficiency between the heating element 28 or the cooling element and the air in the article storage space, and improving the heating or cooling speed of the vehicle refrigerator 2.

[0073] Here, the housing 27 may be the heat exchange housing 212 mentioned above, or a part of the housing 27 may be the heat exchange housing 212 .

[0074] Alternatively, if Figure 2 As shown, the housing 27 has an air duct 244, a first air hole 241, and a second air hole 245. The first air hole 241 and the second air hole 245 both connect the air duct 244 and the article storage space, and the fan 25 is arranged at the first air hole 241 or the second air hole 245. The air duct 244 is arranged in the housing 27, and the fan 25 is arranged at the first air hole 241 or the second air hole 245 connected to the air duct 244, so that the fan 25 can suck the air in the article storage space into the air duct 244 through one of the first air hole 241 or the second air hole 245, and then discharge it into the article storage space through the other of the first air hole 241 or the second air hole 245, so as to accelerate the flow speed of the air in the article storage space.

[0075] In order to improve the working efficiency of the fan 25, optionally, as Figure 2 As shown, the housing 27 includes a housing body 23 and a door 24. The housing body 23 has an opening, and the door 24 is arranged at the opening. The housing body 23 and the door 24 together define an article storage space. The first air hole 241 is arranged on the door 24 or the housing body 23, and the second air hole 245 is arranged on the door 24 or the housing body 23.

[0076] That is to say, the first air hole 241 and the second air hole 245 can both be set on the box door 24; the first air hole 241 and the second air hole 245 can also both be set on the shell body 23; the first air hole 241 and the second air hole 245 can also be set one on the box door 24 and the other on the shell body 23.

[0077] Alternatively, if Figure 2 As shown, the door 24 includes a door body 242 and an air duct baffle 243. The air duct baffle 243 is arranged on the inner side of the door body 242 and defines an air duct 244 with the inner wall of the door body 242. The first air hole 241 and the second air hole 245 are both arranged on the air duct baffle 243. The fan 25 is located in the air duct 244 and installed on the door body 242. The fan 25 corresponds to the first air hole 241, and the second air hole 245 is located between the first air hole 241 and the inner wall of the shell body 23. The air duct 244 and the fan 25 are arranged on the door 24. On the one hand, the volume occupied by the air duct 244 in the article storage space can be reduced, thereby increasing the volume of the vehicle refrigerator 2; on the other hand, the first air hole 241 for installing the fan 25 is arranged on the door 24, which can reduce the probability that the first air hole 241 is blocked by the articles in the article storage space, thereby ensuring the fan 25 The effect of improving the air flow in the article storage space.

[0078] Since the second air hole 245 is located between the first air hole 241 and the inner wall of the shell body 23, that is, the first air hole 241 can be located at or close to the center of the box door 24, and the second air hole 245 can be close to the shell body 23, the air sucked in from the middle of the box door 24 can be discharged from the side close to the box door 24, thereby reducing the probability of the air discharged from the second air hole 245 being blocked, forming a circulating airflow that is sucked in from the middle and discharged from one side, thereby accelerating the air flow speed in the item storage space.

[0079] Optionally, there may be two second air holes 245, which are respectively located on both sides of the first air hole 241, thereby forming a circulating airflow that is sucked in from the middle and discharged from both sides, so that the air circulation range is larger and the efficiency is higher.

[0080] In order to enable the outlet of the compressor 1 to be selectively connected or cut off with the first port of the refrigerator heat exchanger 21 and the inlet of the heat exchange module 3, in one embodiment provided in the present disclosure, as Figure 1 , Figure 4 and Figure 5 As shown, the vehicle thermal management system 100 further includes a first switch valve 5 and a second switch valve 6, the inlet of the first switch valve 5 and the inlet of the second switch valve 6 are both connected to the outlet of the compressor 1, the outlet of the first switch valve 5 is connected to the inlet of the heat exchange module 3, and the outlet of the second switch valve 6 is connected to the first port of the refrigerator heat exchanger 21. In the cooling mode of the vehicle refrigerator 2, as shown in FIG. Figure 7 As shown, the first switch valve 5 is opened, and the outlet of the compressor 1 can be connected to the inlet of the heat exchange module 3; in the heating mode of the vehicle refrigerator 2, as shown Figure 8 As shown, the second switch valve 6 is opened, and the outlet of the compressor 1 can be connected to the first port of the refrigerator heat exchanger 21.

[0081] In another embodiment provided in the present disclosure, Figure 3 As shown, the vehicle thermal management system 100 further includes a first three-way valve 7, wherein the port A of the first three-way valve 7 is connected to the outlet of the compressor 1, the port B of the first three-way valve 7 is connected to the inlet of the heat exchange module 3, and the port C of the first three-way valve 7 is connected to the first port of the refrigerator heat exchanger 21. In the cooling mode of the vehicle refrigerator 2, the ports A and B of the first three-way valve 7 are connected, and the outlet of the compressor 1 can be connected to the inlet of the heat exchange module 3; in the heating mode of the vehicle refrigerator 2, the ports A and C of the first three-way valve 7 are connected, and the outlet of the compressor 1 can be connected to the first port of the refrigerator heat exchanger 21.

[0082] Thus, the vehicle refrigerator 2 can be switched between different modes by the first switch valve 5 and the second switch valve 6, or the first three-way valve 7. The first three-way valve 7 can also reduce the number of valves and the complexity of the vehicle thermal management system.

[0083] In order to achieve that the second port of the refrigerator expansion valve 4 is selectively connected to the inlet of the heat exchange module 3 or the outlet of the heat exchange module 3, in one embodiment provided in the present disclosure, as Figure 1 and Figure 5 As shown, the vehicle thermal management system further includes a first one-way valve 8 and a second one-way valve 9. The second port of the refrigerator expansion valve 4 is connected to the inlet of the heat exchange module 3 via the first one-way valve 8, and the outlet of the heat exchange module 3 is connected to the second port of the refrigerator expansion valve 4 via the second one-way valve 9. Figure 7 As shown, the outlet of the compressor 1 can be connected to the inlet of the heat exchange module 3, and the outlet of the heat exchange module 3 is connected to the second port of the refrigerator expansion valve 4 through the second one-way valve 9. Due to the one-way cut-off function of the first one-way valve 8, the refrigerant cannot flow from the inlet of the heat exchange module 3 to the second port of the refrigerator expansion valve 4. In the heating mode of the vehicle refrigerator 2, as shown in FIG. Figure 8 As shown, the outlet of the compressor 1 can be connected to the first port of the refrigerator heat exchanger 21, the second port of the refrigerator heat exchanger 21 is connected to the first port of the refrigerator expansion valve 4, and the second port of the refrigerator expansion valve 4 is connected to the inlet of the heat exchange module 3 through the first one-way valve 8. Due to the one-way cut-off function of the second one-way valve 9, the refrigerant cannot flow from the second port of the refrigerator expansion valve 4 to the outlet of the heat exchange module 3.

[0084] In another embodiment provided by the present disclosure, Figure 4As shown, the vehicle thermal management system 100 further includes a third switch valve 10 and a fourth switch valve 11, the second port of the refrigerator expansion valve 4 is connected to the inlet of the heat exchange module 3 via the third switch valve 10, and the outlet of the heat exchange module 3 is connected to the second port of the refrigerator expansion valve 4 via the fourth switch valve 11. In the cooling mode of the vehicle refrigerator 2, the fourth switch valve 11 is opened to connect the outlet of the heat exchange module 3 with the second port of the refrigerator expansion valve 4; in the heating mode of the vehicle refrigerator, the third switch valve 10 is opened, and the second port of the refrigerator expansion valve 4 is connected to the inlet of the heat exchange module 3.

[0085] In another embodiment provided by the present disclosure, Figure 3 As shown, the vehicle thermal management system 100 further includes a second three-way valve 12, wherein the port A of the second three-way valve 12 is connected to the second port of the refrigerator expansion valve 4, the port B of the second three-way valve 12 is connected to the inlet of the heat exchange module 3, and the port C of the second three-way valve 12 is connected to the outlet of the heat exchange module 3. In the cooling mode of the vehicle refrigerator 2, the port C and the port A of the second three-way valve 12 are connected, so that the outlet of the heat exchange module 3 is connected to the second port of the refrigerator expansion valve 4; in the heating mode of the vehicle refrigerator 2, the port B and the port A of the second three-way valve 12 are connected, so that the second port of the refrigerator expansion valve 4 is connected to the inlet of the heat exchange module 3.

[0086] In order to achieve that the inlet of the compressor 1 can be selectively connected to the first port of the refrigerator heat exchanger 21 or the outlet of the heat exchange module 3, in one embodiment provided in the present disclosure, as Figure 1 , Figure 4 and Figure 5 As shown, the vehicle thermal management system 100 further includes a fifth switch valve 13 and a sixth switch valve 14, the outlet of the heat exchange module 3 is connected to the inlet of the compressor 1 via the fifth switch valve 13, and the first port of the refrigerator heat exchanger 21 is connected to the inlet of the compressor 1 via the sixth switch valve 14. Figure 7 As shown, in the refrigeration mode of the vehicle refrigerator 2, the sixth switch valve 14 is opened, and the refrigerant flowing out of the first port of the refrigerator heat exchanger 21 returns to the compressor 1 through the sixth switch valve 14; Figure 8 As shown, in the heating mode of the vehicle refrigerator 2 , the fifth switch valve 13 is opened, and the refrigerant flowing out of the outlet of the heat exchange module 3 returns to the compressor 1 through the fifth switch valve 13 .

[0087] In another embodiment provided by the present disclosure, Figure 3As shown, the vehicle thermal management system 100 further includes a third three-way valve 15, wherein the port A of the third three-way valve 15 is connected to the inlet of the compressor 1, the port B of the third three-way valve 15 is connected to the outlet of the heat exchange module 3, and the port C of the third three-way valve 15 is connected to the first port of the refrigerator heat exchanger 21. In the cooling mode of the vehicle refrigerator 2, the ports A and C of the third three-way valve 15 are connected so that the refrigerant flowing out of the first port of the refrigerator heat exchanger 21 returns to the inlet of the compressor 1 through the third three-way valve 15; in the heating mode of the vehicle refrigerator 2, the port B and A of the third three-way valve 15 are connected so that the refrigerant flowing out of the outlet of the heat exchange module 3 returns to the inlet of the compressor 1 through the third three-way valve 15.

[0088] In addition, the heat exchange module 3 can be any module that can make the refrigerant absorb heat or release heat at the heat exchange module 3. For example, in one embodiment provided in the present disclosure, Figure 1 As shown, the heat exchange module 3 includes an outdoor heat exchanger 31, the outlet of the compressor 1 and the second port of the refrigerator expansion valve 4 are both connected to the inlet of the outdoor heat exchanger 31, and the inlet of the compressor 1 and the second port of the refrigerator expansion valve 4 are both connected to the outlet of the outdoor heat exchanger 31. The refrigerant can exchange heat with the outside atmosphere at the outdoor heat exchanger 31, that is, absorb heat from the outside atmosphere or release heat to the outside atmosphere.

[0089] In another embodiment provided by the present disclosure, Figure 1 As shown, the heat exchange module 3 includes an on-board electrical device 32, a plate heat exchanger 33, a first flow path 34, and a second flow path 35. The outlet of the compressor 1 and the second port of the refrigerator expansion valve 4 are both connected to the first inlet of the plate heat exchanger 33, the inlet of the compressor 1 and the second port of the refrigerator expansion valve 4 are also connected to the first outlet of the plate heat exchanger 33, the outlet of the first flow path 34 is connected to the second inlet of the plate heat exchanger 33, the second outlet of the plate heat exchanger 33 is connected to the inlet of the second flow path 35, the outlet of the second flow path 35 is connected to the inlet of the first flow path 34, and the on-board electrical device 32 is arranged on the first flow path 34 and / or the second flow path 35. The refrigerant can absorb the heat of the on-board electrical device 32 through the plate heat exchanger 33 or release heat to the on-board electrical device 32.

[0090] In another embodiment provided by the present disclosure, Figure 1As shown, the heat exchange module 3 includes an outdoor heat exchanger 31, the outlet of the compressor 1 and the second port of the refrigerator expansion valve 4 are both connected to the inlet of the outdoor heat exchanger 31, and the inlet of the compressor 1 and the second port of the refrigerator expansion valve 4 are both connected to the outlet of the outdoor heat exchanger 31. The heat exchange module 3 also includes an on-board electrical device 32, a plate heat exchanger 33, a first flow path 34 and a second flow path 35, the outlet of the compressor 1 and the second port of the refrigerator expansion valve 4 are both connected to the first inlet of the plate heat exchanger 33, the inlet of the compressor 1 and the second port of the refrigerator expansion valve 4 are also connected to the first outlet of the plate heat exchanger 33, the outlet of the first flow path 34 is connected to the second inlet of the plate heat exchanger 33, the second outlet of the plate heat exchanger 33 is connected to the inlet of the second flow path 35, the outlet of the second flow path 35 is connected to the inlet of the first flow path 34, and the on-board electrical device 32 is arranged on the first flow path 34 and / or the second flow path 35.

[0091] In the cooling mode of the vehicle refrigerator 2, the high-temperature and high-pressure refrigerant flowing out of the outlet of the compressor 1 can flow into the outdoor heat exchanger 31 and / or the plate heat exchanger 33, release heat to the outside atmosphere through the outdoor heat exchanger 31 and / or release heat to the vehicle electrical components 32 through the plate heat exchanger 33, and obtain the cooled refrigerant. In the heating mode of the vehicle refrigerator 2, the high-temperature and high-pressure refrigerant flowing out of the outlet of the compressor 1 flows into the refrigerator heat exchanger 21, and then flows into the outdoor heat exchanger 31 and / or flows into the plate heat exchanger 33 through the refrigerator expansion valve 4, absorbs heat from the outside atmosphere through the outdoor heat exchanger 31 and / or absorbs heat from the vehicle electrical components 32 through the plate heat exchanger 33, and finally returns to the compressor 1.

[0092] Since the heat sources and destinations of the outdoor heat exchanger 31 and the plate heat exchanger 33 are different, different heat exchangers can be selected according to the conditions of the vehicle-mounted electrical device 32 and the outdoor temperature during use. For example, when the vehicle-mounted refrigerator 2 needs to be cooled and the vehicle-mounted electrical device 32 needs to be heated (for example, the vehicle-mounted electrical device 32 is a battery pack, and the battery pack needs to be preheated or heated), the high-temperature and high-pressure refrigerant flowing out of the compressor 1 can be introduced into the plate heat exchanger 33, and the coolant in the first flow path 34 is heated by the refrigerant, so that the heated coolant increases the temperature of the vehicle-mounted electrical device 32. For example, when the vehicle-mounted refrigerator 2 needs to be heated and the ambient temperature is low, the refrigerant flowing out of the refrigerator expansion valve 4 can be introduced into the plate heat exchanger 33, and the plate heat exchanger 33 absorbs the heat of the vehicle-mounted electrical device 32 to improve the heating effect of the vehicle-mounted refrigerator 2.

[0093] The present disclosure does not limit the specific type of the on-board electrical device 32 . For example, the on-board electrical device 32 may include one or more of a battery pack, a motor, a motor controller, and a DC-DC converter.

[0094] Alternatively, if Figure 1As shown, the heat exchange module 3 further includes a seventh switch valve 36 and an eighth switch valve 37. The outlet of the compressor 1 and the second port of the refrigerator expansion valve 4 are both connected to the inlet of the outdoor heat exchanger 31 via the seventh switch valve 36, and the outlet of the compressor 1 and the second port of the refrigerator expansion valve 4 are both connected to the first inlet of the plate heat exchanger 33 via the eighth switch valve 37. By controlling the opening and closing of the seventh switch valve 36 and the eighth switch valve 37, it is possible to control whether the refrigerant flowing out of the outlet of the compressor 1 flows into the outdoor heat exchanger 31 to release heat or flows into the plate heat exchanger 33 to release heat in the cooling mode of the vehicle refrigerator 2, and control whether the refrigerant flowing out of the refrigerator expansion valve 4 flows into the outdoor heat exchanger 31 to absorb heat or flows into the plate heat exchanger 33 to absorb heat in the heating mode of the vehicle refrigerator 2.

[0095] Alternatively, if Figure 1 As shown, the heat exchange module 3 also includes a radiator 38 and a fourth three-way valve 39, the A port of the fourth three-way valve 39 is connected to the inlet of the first flow path 34, the outlet of the second flow path 35 is connected to the B port of the fourth three-way valve 39 and the inlet of the radiator 38, and the C port of the fourth three-way valve 39 is connected to the outlet of the radiator 38.

[0096] When the A port and the B port of the fourth three-way valve 39 are connected, the first flow path 34, the plate heat exchanger 33, and the second flow path 35 are connected in series to form a loop. The heat of the on-board electrical components 32 can be dissipated to the refrigerant through the plate heat exchanger 33, so that the refrigerant can absorb heat at the on-board electrical components 32, and the on-board electrical components 32 can be cooled.

[0097] When port A and port C of the fourth three-way valve 39 are connected, the first flow path 34, the radiator 38, the plate heat exchanger 33, and the second flow path 35 are connected in series to form a loop. The refrigerant can dissipate heat to the coolant through the plate heat exchanger 33, and the coolant dissipates heat to the outside atmosphere through the radiator 38 when flowing through the radiator 38.

[0098] Optionally, a water pump 42 is provided on the first flow path 34 or the second flow path 35 .

[0099] Optionally, the vehicle thermal management system 100 also includes an air conditioning system, and the air conditioning system includes the above-mentioned compressor 1, that is, the compressor 1 connected to the refrigerator heat exchanger 21 is the compressor 1 of the air conditioning system. In other words, the compressor 1 not only compresses and drives the refrigerant in the refrigerant flow path where the equipment in the air conditioning system (such as the air conditioning evaporator 19, the air conditioning condenser 16, etc.) is located, but also compresses and drives the refrigerant in the refrigerant flow path where the refrigerator heat exchanger 21 of the vehicle refrigerator 2 is located, so as to achieve the effect of using the same compressor 1 to provide refrigerant for different thermal management equipment.

[0100] Utilizing the compressor 1 in the air-conditioning system to provide flowing refrigerant for the refrigerator heat exchanger 21 of the vehicle refrigerator 2 can also improve the utilization rate of the compressor 1, increase the integration of the vehicle thermal management system 100, reduce the number of devices required for cooling or heating the vehicle refrigerator 2, and avoid a significant increase in costs due to the installation of the vehicle refrigerator 2.

[0101] Alternatively, if Figure 1 As shown, the air-conditioning system also includes an air-conditioning condenser 16, a flow path 17 and a throttling path 18. The outlet of the compressor 1 is connected to the inlet of the air-conditioning condenser 16, and the outlet of the air-conditioning condenser 16 is selectively connected to the inlet of the heat exchange module 3 via the flow path 17 or the throttling path 18.

[0102] In the heating mode of the air conditioning system, Fig.10 As shown, the outlet of the air conditioning condenser 16 is connected to the throttling flow path 18. After the high-temperature and high-pressure refrigerant flowing out of the outlet of the compressor 1 flows into the air conditioning condenser 16, it will release heat in the air conditioning condenser 16. After the refrigerant releases heat, it passes through the throttling flow path 18 to be throttled and reduced in pressure, and then becomes a low-temperature and low-pressure gaseous refrigerant. The low-temperature and low-pressure gaseous refrigerant absorbs heat in the heat exchange module 3 and finally returns to the compressor 1. Since the refrigerant releases heat in the air conditioning condenser 16, it can provide heat for the passenger compartment and increase the temperature in the passenger compartment. Fig.12 As shown, in the synchronous heating mode of the vehicle refrigerator and the air conditioning system, the outlet of the air conditioning condenser 16 is connected to the throttling flow path 18.

[0103] like Figure 1 As shown, the air conditioning system also includes an air conditioning evaporator 19 and a first air conditioning expansion valve 20 , the outlet of the heat exchange module 3 is connected to the inlet of the air conditioning evaporator 19 via the first air conditioning expansion valve 20 , and the outlet of the air conditioning evaporator 19 is connected to the inlet of the compressor 1 .

[0104] In the cooling mode of the air conditioner, Fig. 9 As shown, the outlet of the air-conditioning condenser 16 is connected to the flow path 17, and the high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the compressor 1 flows into the air-conditioning condenser 16. At this time, the heating fan 40 can be controlled not to blow air to the air-conditioning condenser 16, that is, the refrigerant does not exchange heat at the air-conditioning condenser 16, and the air-conditioning condenser 16 is used as a flow path, and the refrigerant flowing out of the air-conditioning condenser 16 flows into the flow path 17. Since the refrigerant flowing through the flow path 17 has not been throttled and depressurized, the refrigerant flowing into the heat exchange module 3 is still a high-temperature and high-pressure gaseous refrigerant. After releasing heat through the heat exchange module 3, the high-temperature and high-pressure gaseous refrigerant can flow to the first air-conditioning expansion valve 20, and after throttling and depressurizing by the first air-conditioning expansion valve 20, it flows into the air-conditioning evaporator 19, absorbs the heat of the passenger compartment in the air-conditioning evaporator 19, cools the passenger compartment, and realizes refrigeration of the passenger compartment. As shown Fig.11As shown, in the synchronous cooling mode of the vehicle refrigerator and the air-conditioning system, the outlet of the air-conditioning condenser 16 is connected to the flow path 17, and the heating fan 40 does not blow air to the air-conditioning condenser 16, that is, the refrigerant does not exchange heat at the air-conditioning condenser 16, and the air-conditioning condenser 16 is used as a flow path, and the flow path 17 only allows the refrigerant to pass, and will not throttle or reduce the pressure of the refrigerant.

[0105] like Figure 1 As shown, in one embodiment provided in the present disclosure, a first switch valve 5 is provided on the flow path 17, and a second air-conditioning expansion valve 181 is provided on the throttling path 18, so that the flow path 17 can conduct or cut off the refrigerant through the first switch valve 5, and the throttling path 18 can cut off or throttle the refrigerant through the second air-conditioning expansion valve 181.

[0106] In another embodiment provided by the present disclosure, Figure 5 As shown, the air conditioning system further includes an expansion switch valve 26, the inlet of the expansion switch valve 26 is connected to the outlet of the air conditioning condenser 16, the outlet of the expansion switch valve 26 is connected to the inlet of the heat exchange module 3, the through-flow path 17 is a through-flow channel in the expansion switch valve 26, the through-flow channel can conduct or cut off the refrigerant, and the throttling flow path 18 is a throttling channel in the expansion switch valve 26, the throttling channel can cut off or throttle the refrigerant. The expansion switch valve 26 can be regarded as an integrated valve integrating the expansion valve and the switch valve.

[0107] For an embodiment in which the air conditioning system includes an expansion switch valve 26, as shown in FIG. Figure 5 As shown, the first switch valve 5 can be arranged at the inlet of the air conditioning condenser 16 .

[0108] Alternatively, if Figure 1 As shown, the air conditioning system further includes a heating fan 40 and an electric heater 41. The electric heater 41 is arranged near the air conditioning condenser 16, and the heating fan 40 is used to blow air to the air conditioning condenser 16 and the electric heater 41. The heating fan 40 can generate wind blowing through the air conditioning condenser 16 or the electric heater 41 when the air conditioning system is in heating mode, so that the air in the vehicle passenger compartment can exchange heat with the air conditioning condenser 16 or the electric heater 41 to increase the temperature in the passenger compartment.

[0109] Optionally, the electric heater 41 may be a PTC heater.

[0110] Alternatively, if Figure 1As shown, the air-conditioning system also includes a gas-liquid separator 30, the inlet of the gas-liquid separator 30 is connected to the first port of the refrigerator heat exchanger 21, the outlet of the heat exchange module 3 and the outlet of the air-conditioning evaporator 19, and the outlet of the gas-liquid separator 30 is connected to the inlet of the compressor 1, so that the refrigerant flowing out from the first port of the refrigerator heat exchanger 21, the outlet of the heat exchange module 3 and the outlet of the air-conditioning evaporator 19 can pass through the gas-liquid separator 30 before returning to the compressor 1, so that the liquid and gas in the refrigerant are separated, thereby allowing the gaseous refrigerant to return to the compressor 1 to prevent the compressor 1 from being damaged.

[0111] To facilitate understanding of the working mode of the vehicle thermal management system provided by the present disclosure, the following will be Figure 1 As an example, the embodiment shown in FIG. Figures 7 to 12 , specifically introduces the working processes of several main working modes of a vehicle thermal management system provided by an embodiment of the present disclosure.

[0112] 1. Car refrigerator cooling mode

[0113] See also Figure 7 In this mode, the first switch valve 5 is opened, the second air conditioning expansion valve 181 is closed, the second switch valve 6 is closed, at least one of the seventh switch valve 36 and the eighth switch valve 37 is opened, the refrigerator expansion valve 4 is opened, the sixth switch valve 14 is opened, the fifth switch valve 13 is closed, the first air conditioning expansion valve 20 is closed, and the heating fan 40 is closed. In this mode, the compressor 1, the air conditioning condenser 16, the heat exchange module 3, the refrigerator expansion valve 4, and the refrigerator heat exchanger 21 are connected in series in sequence to form a loop.

[0114] The high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the compressor 1 flows into the air conditioning condenser 16. Since the heating fan 40 is turned off, that is, the heating fan 40 does not blow air to the air conditioning condenser 16, the high-temperature and high-pressure gaseous refrigerant does not release heat at the air conditioning condenser 16. The air conditioning condenser 16 is used as a flow passage. The high-temperature and high-pressure gaseous refrigerant flows into the heat exchange module 3 and releases heat in the heat exchange module 3. The refrigerant flowing out of the outlet of the heat exchange module 3 is throttled and reduced in pressure by the refrigerator expansion valve 4 to become a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant flows into the refrigerator heat exchanger 21, absorbs the heat of the item storage space in the refrigerator heat exchanger 21, and reduces the temperature in the item storage space to realize the refrigeration or freezing function of the vehicle refrigerator 2. After absorbing heat in the refrigerator heat exchanger 21, the refrigerant finally returns to the compressor 1.

[0115] It should be noted that in this mode, if the seventh switch valve 36 is opened, the high-temperature and high-pressure gaseous refrigerant flows into the outdoor heat exchanger 31, and releases heat to the outside atmosphere in the outdoor heat exchanger 31; if the eighth switch valve 37 is opened, and the A port and the B port of the fourth three-way valve 39 are connected, the high-temperature and high-pressure gaseous refrigerant flows into the plate heat exchanger 33, and releases heat to the coolant in the plate heat exchanger 33, and the coolant after absorbing heat can be used to heat the on-board electrical components 32 when flowing through the on-board electrical components 32. For example, when the on-board electrical components 32 include a battery pack, the heat of the refrigerant can be used to heat the battery pack; if the eighth switch valve 37 is opened, and the A port and the C port of the fourth three-way valve 39 are connected, the high-temperature and high-pressure gaseous refrigerant flows into the plate heat exchanger 33, and releases heat to the coolant in the plate heat exchanger 33, and the coolant after absorbing heat can release heat to the outside atmosphere through the radiator 38 when flowing through the radiator 38.

[0116] In addition, in the refrigeration mode of the vehicle refrigerator, the cooling element of the vehicle refrigerator 2 can also be turned on to improve the refrigeration efficiency and achieve rapid refrigeration.

[0117] 2. Car refrigerator heating mode

[0118] See also Figure 8 In this mode, the first switch valve 5 is closed, the second air conditioning expansion valve 181 is closed, the second switch valve 6 is opened, at least one of the seventh switch valve 36 and the eighth switch valve 37 is opened, the refrigerator expansion valve 4 is opened, the sixth switch valve 14 is closed, the fifth switch valve 13 is opened, and the first air conditioning expansion valve 20 is closed. In this mode, the compressor 1, the refrigerator heat exchanger 21, the refrigerator expansion valve 4, and the heat exchange module 3 are connected in series in sequence to form a loop.

[0119] The high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the compressor 1 flows into the refrigerator heat exchanger 21 and releases heat in the refrigerator heat exchanger 21 to increase the temperature of the item storage space, thereby realizing the insulation or heating function of the vehicle refrigerator 2. The refrigerant that releases heat at the refrigerator heat exchanger 21 flows into the refrigerator expansion valve 4 and is throttled and depressurized to become a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant flows into the heat exchange module 3 and absorbs heat in the heat exchange module 3. The outlet of the heat exchange module 3 flows out a low-temperature and low-pressure gaseous refrigerant, which eventually returns to the compressor 1.

[0120] It should be noted that in this mode, if the seventh switch valve 36 is opened, the low-temperature and low-pressure liquid refrigerant flows into the outdoor heat exchanger 31, and absorbs heat from the outside atmosphere in the outdoor heat exchanger 31; if the eighth switch valve 37 is opened, and the A port and the B port of the fourth three-way valve 39 are connected, the low-temperature and low-pressure liquid refrigerant flows into the plate heat exchanger 33, and absorbs the heat of the coolant in the plate heat exchanger 33. The coolant after releasing heat can be used to cool the on-board electrical components 32 when flowing through the on-board electrical components 32. For example, when the on-board electrical components 32 include a motor, the cooling capacity of the refrigerant can be used to dissipate heat from the motor.

[0121] In addition, in the heating mode of the vehicle refrigerator, the heating element 28 of the vehicle refrigerator 2 can also be turned on to improve the heating efficiency and achieve rapid heating.

[0122] 3. Air conditioning system cooling mode

[0123] See also Fig. 9 In this mode, the first switch valve 5 is opened, the second air conditioning expansion valve 181 is closed, the second switch valve 6 is closed, at least one of the seventh switch valve 36 and the eighth switch valve 37 is opened, the refrigerator expansion valve 4 is closed, the sixth switch valve 14 is closed, the fifth switch valve 13 is closed, the second check valve 9 is closed, the first air conditioning expansion valve 20 is opened, and the heating fan 40 is closed. In this mode, the compressor 1, the air conditioning condenser 16, the heat exchange module 3, the first air conditioning expansion valve 20, and the air conditioning evaporator 19 are connected in series in sequence to form a loop.

[0124] The high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the compressor 1 flows into the air conditioning condenser 16. Since the heating fan 40 is turned off, that is, the heating fan 40 does not blow air to the air conditioning condenser 16, the high-temperature and high-pressure gaseous refrigerant does not release heat at the air conditioning condenser 16. The air conditioning condenser 16 is used as a flow passage. The high-temperature and high-pressure gaseous refrigerant flows into the heat exchange module 3 and releases heat in the heat exchange module 3. The refrigerant flowing out of the outlet of the heat exchange module 3 is throttled and reduced in pressure by the first air conditioning expansion valve 20 to become a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant flows into the air conditioning evaporator 19, absorbs the heat of the passenger compartment in the air conditioning evaporator 19, and reduces the temperature of the passenger compartment to achieve air conditioning refrigeration. After absorbing heat in the air conditioning evaporator 19, the refrigerant finally returns to the compressor 1.

[0125] It should be noted that in this mode, if the seventh switch valve 36 is opened, the high-temperature and high-pressure gaseous refrigerant flows into the outdoor heat exchanger 31, and releases heat to the outside atmosphere in the outdoor heat exchanger 31; if the eighth switch valve 37 is opened, and the A port and the B port of the fourth three-way valve 39 are connected, the high-temperature and high-pressure gaseous refrigerant flows into the plate heat exchanger 33, and releases heat to the coolant in the plate heat exchanger 33, and the coolant after absorbing heat can be used to heat the on-board electrical components 32 when flowing through the on-board electrical components 32. For example, when the on-board electrical components 32 include a battery pack, the heat of the refrigerant can be used to heat the battery pack; if the eighth switch valve 37 is opened, and the A port and the C port of the fourth three-way valve 39 are connected, the high-temperature and high-pressure gaseous refrigerant flows into the plate heat exchanger 33, and releases heat to the coolant in the plate heat exchanger 33, and the coolant after absorbing heat can release heat to the outside atmosphere through the radiator 38 when flowing through the radiator 38.

[0126] In addition, for the dehumidification mode, the flow path of the refrigerant is the same as that of the air conditioning system in the cooling mode, that is, the high-humidity air in the vehicle passenger compartment is cooled by the low temperature of the air conditioning evaporator 19, and condensed water is precipitated to achieve the effect of removing moisture from the air. After dehumidification by the air conditioning evaporator 19, if temperature compensation is required, the heating fan 40 can be turned on to release heat to the passenger compartment when the refrigerant flows through the air conditioning condenser 16.

[0127] In addition, in the cooling mode of the air-conditioning system, if the vehicle refrigerator 2 has a heating demand, the heating element 28 of the vehicle refrigerator 2 can be turned on to achieve heating of the vehicle refrigerator 2.

[0128] 4. Heating mode of air conditioning system

In this mode, the compressor 1, the air conditioning condenser 16, the second air conditioning expansion valve 181, and the heat exchange module 3 are connected in series in sequence to form a loop.

[0130] The high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the compressor 1 flows into the air-conditioning condenser 16 and releases heat in the ice air-conditioning condenser 16 to increase the temperature of the passenger compartment and achieve air-conditioning heating. The refrigerant that releases heat at the air-conditioning condenser 16 flows into the second air-conditioning expansion valve 181 and is throttled and reduced in pressure to become a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant flows into the heat exchange module 3 and absorbs heat in the heat exchange module 3. The outlet of the heat exchange module 3 flows out a low-temperature and low-pressure gaseous refrigerant, which eventually returns to the compressor 1.

[0131] It should be noted that in this mode, if the seventh switch valve 36 is opened, the low-temperature and low-pressure liquid refrigerant flows into the outdoor heat exchanger 31, and absorbs heat from the outside atmosphere in the outdoor heat exchanger 31; if the eighth switch valve 37 is opened, and the A port and the B port of the fourth three-way valve 39 are connected, the low-temperature and low-pressure liquid refrigerant flows into the plate heat exchanger 33, and absorbs the heat of the coolant in the plate heat exchanger 33. The coolant after releasing heat can be used to cool the on-board electrical components 32 when flowing through the on-board electrical components 32. For example, when the on-board electrical components 32 include a motor, the cooling capacity of the refrigerant can be used to dissipate heat from the motor.

[0132] In addition, for the defog mode, the flow path of the refrigerant is the same as that of the air conditioning system heating mode. The low-temperature air is heated to high-temperature air when passing through the air conditioning condenser 16. The high-temperature air is blown to the vehicle's glass through the defog channel to remove the fog beads on the glass.

[0133] In addition, in the heating mode of the air-conditioning system, if the vehicle refrigerator 2 has a cooling demand, the cooling element of the vehicle refrigerator 2 can be turned on to achieve the cooling of the vehicle refrigerator 2.

[0136] The high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the compressor 1 flows into the air-conditioning condenser 16. Since the heating fan 40 is turned off, that is, the heating fan 40 does not blow air to the air-conditioning condenser 16, the high-temperature and high-pressure gaseous refrigerant does not release heat at the air-conditioning condenser 16. The air-conditioning condenser 16 is used as a flow passage. The high-temperature and high-pressure gaseous refrigerant flows into the heat exchange module 3 and releases heat in the heat exchange module 3. The refrigerant flowing out of the outlet of the heat exchange module 3 is divided into two paths. One path of the refrigerant becomes a low-temperature and low-pressure path after throttling and reducing the pressure by the refrigerator expansion valve 4. Liquid refrigerant, the low-temperature and low-pressure liquid refrigerant flows into the refrigerator heat exchanger 21, absorbs the heat of the item storage space in the refrigerator heat exchanger 21, reduces the temperature in the item storage space, and realizes the refrigeration or freezing function of the vehicle refrigerator 2. The other refrigerant is throttled and reduced in pressure by the first air-conditioning expansion valve 20 to become a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant flows into the air-conditioning evaporator 19, absorbs the heat of the passenger compartment in the air-conditioning evaporator 19, reduces the temperature of the passenger compartment, and realizes air-conditioning refrigeration. After absorbing heat in the air-conditioning evaporator 19 and the refrigerator heat exchanger 21, the refrigerant finally converges and returns to the compressor 1.

[0137] It should be noted that in this mode, if the seventh switch valve 36 is opened, the high-temperature and high-pressure gaseous refrigerant flows into the outdoor heat exchanger 31, and releases heat to the outside atmosphere in the outdoor heat exchanger 31; if the eighth switch valve 37 is opened, and the A port and the B port of the fourth three-way valve 39 are connected, the high-temperature and high-pressure gaseous refrigerant flows into the plate heat exchanger 33, and releases heat to the coolant in the plate heat exchanger 33, and the coolant after absorbing heat can be used to heat the on-board electrical components 32 when flowing through the on-board electrical components 32. For example, when the on-board electrical components 32 include a battery pack, the heat of the refrigerant can be used to heat the battery pack; if the eighth switch valve 37 is opened, and the A port and the C port of the fourth three-way valve 39 are connected, the high-temperature and high-pressure gaseous refrigerant flows into the plate heat exchanger 33, and releases heat to the coolant in the plate heat exchanger 33, and the coolant after absorbing heat can release heat to the outside atmosphere through the radiator 38 when flowing through the radiator 38.

[0140] The high-temperature and high-pressure gaseous refrigerant flowing out of the outlet of the compressor 1 is divided into two paths. One path of the refrigerant flows into the air-conditioning condenser 16 and releases heat in the ice air-conditioning condenser 16 to increase the temperature of the passenger compartment and realize air-conditioning heating. The other path of the refrigerant flows into the refrigerator heat exchanger 21 and releases heat in the refrigerator heat exchanger 21 to increase the temperature of the item storage space and realize the insulation or heating function of the vehicle refrigerator 2. The refrigerant that releases heat at the refrigerator heat exchanger 21 flows into the heat exchange module 3 after throttling and reducing the pressure through the refrigerator expansion valve 4. The refrigerant that releases heat at the air-conditioning condenser 16 flows into the heat exchange module 3 after throttling and reducing the pressure through the second air-conditioning expansion valve 181. The refrigerant absorbs heat in the heat exchange module 3, and the outlet of the heat exchange module 3 flows out a low-temperature and low-pressure gaseous refrigerant, which eventually returns to the compressor 1.
