[0077] like Figure 1 As shown, the thermal management system provided in this application embodiment includes a compressor 1, a power cooling system, and a heat exchange integrated module.

[0078] like Figure 1 As shown, the compressor 1 in this embodiment is used to output a high-temperature and high-pressure medium, which can be used for refrigerator cooling, heater heating, air conditioning cooling and heating, vehicle battery heating and cooling, and vehicle glass defrosting, etc., which is the same as the meaning commonly understood by those skilled in the art of this application, and will not be repeated here.

[0079] like Figure 1 As shown, the power cooling system in the embodiments of this application is used for motor cooling.

[0080] like Figure 1 As shown, the heat exchange integrated module provided in this application is connected to the compressor 1 and the power cooling system 11, enabling the power cooling system 11 to perform heat dissipation functions. It also enables the compressor 1, along with other components, to perform functions such as refrigerator cooling, heater heating, air conditioning cooling and heating, vehicle battery heating and cooling, and vehicle glass defrosting. It should be noted that the power cooling system 11 can dissipate heat from both the engine and the motor.

[0081] Firstly, such as Figure 1 and Figure 2As shown, this application provides a heat exchange integrated module, including: a first body 3, in which a plurality of refrigerant channels are provided; a valve assembly 4, which is connected to the plurality of refrigerant channels to form at least two refrigerant flow channels; the at least two refrigerant flow channels include a first refrigerant flow channel and a second refrigerant flow channel; one end of the first refrigerant flow channel is adapted to be connected to a compressor 1, and the other end is adapted to be connected to a refrigerator heat exchange module 13; one end of the second refrigerant flow channel is adapted to be connected to the refrigerator heat exchange module 13, and the other end is adapted to be connected to an in-vehicle evaporator 12.

[0082] In this embodiment, by providing several refrigerant channels in the first body 3, the valve assembly 4 is connected to these channels to form at least two refrigerant flow paths. These at least two refrigerant flow paths include a first refrigerant flow path and a second refrigerant flow path. One end of the first refrigerant flow path is connected to the compressor 1, and the other end is connected to the refrigerator heat exchange module 13. One end of the second refrigerant flow path is connected to the refrigerator heat exchange module 13, and the other end is connected to the vehicle evaporator 12. Thus, by configuring the refrigerator heat exchange module 13 and the vehicle evaporator 12 to share a single compressor 1, the refrigerant utilization efficiency is improved, thereby saving energy.

[0083] Specifically, the first body 3 is provided with a ninth interface 339 and a third interface 333 connected to the first refrigerant flow channel, and a second interface 332 and a fourth interface 334 connected to the second refrigerant flow channel. High-temperature and high-pressure refrigerant flows out from the compressor 1, enters the heat exchange integrated module through the ninth interface 339, flows through the first refrigerant flow channel, flows out from the third interface 333, flows through the second throttling valve 415 and then enters the refrigerator heat exchange module 13. After expanding through the seventh expansion valve 416, it flows back into the heat exchange integrated module from the second interface 332 and flows out of the heat exchange integrated module from the fourth interface 334. After passing through the vehicle evaporator 12, it absorbs heat and evaporates, that is, it absorbs heat from the environment, which lowers the temperature of the passenger compartment. Finally, it enters the gas-liquid separator 20 and returns to the compressor 1 for cycle operation, thus realizing the coordinated mode of refrigerator heating and air conditioning cooling.

[0084] In some embodiments, such as Figure 2 As shown, the thermal management system includes a gas-liquid separator 20, which is located at the inlet of the compressor 1. This facilitates the gas-liquid separation of the refrigerant flowing through the evaporator 12 inside the vehicle, thereby improving heat exchange efficiency.

[0085] It should be noted that the vehicle evaporator 12 is used to evaporate the refrigerant and absorb heat from the surrounding air to achieve cooling inside the vehicle; the refrigerator heat exchange module 13 is used to cool or heat the refrigerator.

[0086] Optionally, such as Figure 2 and Figure 20As shown, the heat exchange integrated module also includes a heat exchanger 2, which is installed in the first body 3 and is connected to the second refrigerant channel for heat exchange of the refrigerant flowing through the second refrigerant channel.

[0087] In this embodiment, the heat exchanger 2 is installed in the first body 3 and connected to the second refrigerant channel. The heat exchanger 2 exchanges heat with the refrigerant flowing through the second refrigerant channel. In this way, by exchanging heat with the refrigerant flowing out of the refrigerator heat exchange module 13, the cooling efficiency of the vehicle evaporator 12 is improved.

[0088] Optionally, such as Figure 2 As shown, the second refrigerant flow channel includes a first sub-flow channel and a second sub-flow channel; one end of the first sub-flow channel is adapted to be connected to the refrigerator heat exchange module 13, and the other end is connected to the first input end of the heat exchanger 2; one end of the second sub-flow channel is connected to the first output end of the heat exchanger 2, and the other end is adapted to be connected to the vehicle evaporator 12.

[0089] In this implementation, one end of the first sub-channel is connected to the refrigerator heat exchange module 13, and the other end is connected to the first input end of the heat exchanger 2; one end of the second sub-channel is connected to the first output end of the heat exchanger 2, and the other end is connected to the vehicle evaporator 12. Thus, by setting the first and second sub-channels, the connection between the refrigerator heat exchange module 13 and the heat exchanger 2, as well as the connection between the vehicle evaporator 12 and the heat exchanger 2, are achieved.

[0090] Optionally, such as Figure 2 and Figure 20 As shown, the refrigerant passages also include a third refrigerant passage 303, a fourth refrigerant passage 304, a fifth refrigerant passage 305, and a sixth refrigerant passage 306; the valve assembly 4 includes a first one-way valve 402 and a first expansion valve 403; the third refrigerant passage 303 is adapted to be connected to the refrigerator heat exchange module 13, and the third refrigerant passage 303 is connected to the sixth refrigerant passage 306 through the first one-way valve 402 to form a first sub-channel, and the sixth refrigerant passage 306 is connected to the first input end of the heat exchanger 2; the fifth refrigerant passage 305 is connected to the fourth refrigerant passage 304 through the first expansion valve 403 to form a second sub-channel; the fourth refrigerant passage 304 is connected to the first output end of the heat exchanger 2; the fifth refrigerant passage 305 is adapted to be connected to the vehicle evaporator 12.

[0091] In this embodiment, a third refrigerant channel 303 is connected to the refrigerator heat exchange module 13. The third refrigerant channel 303 is connected to a first sub-channel via a first one-way valve 402 and a sixth refrigerant channel 306. The sixth refrigerant channel 306 is connected to the first input end of the heat exchanger 2. A fifth refrigerant channel 305 is connected to a fourth refrigerant channel 304 via a first expansion valve 403 to form a second sub-channel. The fourth refrigerant channel 304 is connected to the first output end of the heat exchanger 2. The fifth refrigerant channel 305 is connected to the vehicle evaporator 12. In this way, the refrigerant flows into the first input end of the heat exchanger 2 after passing through the first one-way valve 402, preventing the refrigerant from flowing backward. In addition, after passing through the heat exchanger 2, the refrigerant flows out from the fourth refrigerant channel 304 and flows into the fifth refrigerant channel 305 after passing through the first expansion valve 403. This can throttle and reduce the pressure of the high-pressure liquid refrigerant, regulate and control the amount of liquid refrigerant entering the vehicle evaporator 12, and adapt it to changes in the cooling load.

[0092] Specifically, such as Figure 2 As shown, the thermal management system includes a refrigerator heating and air conditioning cooling coordinated mode. In this mode, high-temperature and high-pressure refrigerant flows out from compressor 1, enters the heat exchange integrated module through the ninth interface 339, flows into the second refrigerant channel 302 after passing through the first refrigerant channel 301 and the first solenoid valve 401, flows out from the third interface 333, flows through the second throttling valve 415 and enters the refrigerator heat exchange module 13. In the refrigerator heat exchange module 13, the refrigerant condenses and releases heat, completing the heating of the items inside the refrigerator. Then it flows through the throttling seventh expansion valve 41. 6. The refrigerant expands from the second interface 332 into the third refrigerant channel 303, passes through the first one-way valve 402 into the heat exchanger 2 for heat absorption and evaporation. The refrigerant coming out of the heat exchanger 2 passes through the fourth refrigerant channel 304 into the first expansion valve 403 for throttling and expansion. After throttling and expansion, it passes through the fifth refrigerant channel 305 and flows out of the heat exchange integrated module from the fourth interface 334. After passing through the vehicle evaporator 12, the refrigerant absorbs heat and evaporates, that is, it absorbs heat from the environment, causing the temperature of the passenger compartment to drop. Finally, it enters the gas-liquid separator 20 and returns to the compressor 1 for cycle operation.

[0093] Optionally, such as Figure 3 As shown, the refrigerant passages also include a seventh refrigerant passage 307; the valve assembly 4 includes a second solenoid valve 404, the seventh refrigerant passage 307 is connected to the fourth refrigerant passage 304 through the second solenoid valve 404, and the seventh refrigerant passage 307 is adapted to be connected to the inlet of the compressor 1.

[0094] In this embodiment, the seventh refrigerant channel 307, the second solenoid valve 404, and the fourth refrigerant channel 304 are sequentially connected, and the seventh refrigerant channel 307 is connected to the compressor 1. This facilitates the implementation of the refrigerator's heating mode.

[0095] Specifically, such as Figure 3As shown, the first body 3 is provided with an eighth interface 338 that communicates with the seventh refrigerant channel 307. In the refrigerator heating mode, high-temperature and high-pressure refrigerant flows out from the compressor 1, enters the heat exchange integrated module through the ninth interface 339, flows into the second refrigerant channel 302 after passing through the first refrigerant channel 301 and the first solenoid valve 401, flows out from the third interface 333, flows through the second throttling valve 415 and enters the refrigerator heat exchange module 13. In the refrigerator heat exchange module 13, the refrigerant condenses and releases heat, completing the heating of the items in the refrigerator. Then it flows through the throttling seventh expansion valve 416 to expand, enters the third refrigerant channel 303 through the second interface 332, enters the heat exchanger 2 to absorb heat and evaporate through the first one-way valve 402, and the refrigerant coming out of the heat exchanger 2 enters the second solenoid valve 404 through the fourth refrigerant channel 304, passes through the seventh refrigerant channel 307, flows out of the heat exchange integrated module through the eighth interface 338, and finally enters the gas-liquid separator 20 to return to the compressor 1 for circulation.

[0096] Optionally, such as Figure 4 , Figure 18 As shown, the first body 3 is provided with a first interface 331 and a second interface 332; the valve assembly 4 includes a second one-way valve 405 and a third one-way valve 406; the first interface 331 is adapted to be connected to the compressor 1, the second one-way valve 405 is connected to the first interface 331, the second one-way valve 405 is connected to the fourth refrigerant passage 304, and the second one-way valve 405 is adapted to unidirectionally guide the refrigerant from the first interface 331 to the fourth refrigerant passage 304; the second interface 332 is adapted to be connected to the refrigerator heat exchange module 13, the third one-way valve 406 is connected to the second interface 332, the fourth refrigerant passage 304 is connected to the third one-way valve 406, and the third one-way valve 406 is adapted to unidirectionally guide the refrigerant from the fourth refrigerant passage 304 to the second interface 332.

[0097] In this embodiment, a first interface 331 and a second interface 332 are provided on the first body 3. The first interface 331 is connected to the compressor 1, and a second one-way valve 405 is connected to the first interface 331 and the fourth refrigerant passage 304. The second interface 332 is connected to the refrigerator heat exchange module 13, and a third one-way valve 406 is provided on the second interface 332. The fourth refrigerant passage 304 is connected to the third one-way valve 406. This facilitates the formation of a refrigerator cooling mode.

[0098] Specifically, such as Figure 4 As shown, the thermal management system includes a fourth solenoid valve 414, an external condenser 9, and a refrigerant reservoir 21; the compressor 1 is connected to the external condenser 9 through the fourth solenoid valve 414, the refrigerant reservoir 21 is connected to the external condenser 9, and the refrigerant reservoir 21 is connected to the first interface 331.

[0099] It should be noted that the second one-way valve 405 can be directly installed at the first interface 331, or it can be installed between the first interface 331 and the fourth refrigerant passage 304.

[0100] In refrigerator cooling mode, compressor 1 discharges high-temperature, high-pressure gaseous refrigerant. The refrigerant enters the external condenser 9, where it releases heat and liquefies, becoming a medium-temperature, high-pressure liquid. The refrigerant enters the heat exchange integrated module through the first interface 331, then flows through the second one-way valve 405, the fourth refrigerant channel 304, the third one-way valve 406, and the third refrigerant channel 303, exiting the heat exchange integrated module through the second interface 332. It then expands through the seventh expansion valve 416 and enters the refrigerator heat exchange module 13 to evaporate and absorb heat, lowering the internal temperature of the refrigerator and completing the refrigeration process. After being throttled by the second throttling valve 415, it returns to the thermal management heat exchange integrated module through the third interface 333. Finally, it passes through the second refrigerant channel 302 and enters the gas-liquid separator 20 and compressor 1 through the eighth interface 338 for cyclic operation.

[0101] In some embodiments, such as Figure 5 As shown, the thermal management system also includes a refrigerator cooling and air conditioning cooling coordinated mode. In this mode, compressor 1 discharges high-temperature, high-pressure gaseous refrigerant, which enters the external condenser 9. After releasing heat and liquefying in the external condenser 9, the refrigerant becomes a medium-temperature, high-pressure liquid. The refrigerant enters the heat exchange integrated module through the first interface 331, and then passes through the second one-way valve 405. In the fourth refrigerant channel 304, it is divided into two paths. The first path enters the first expansion valve 403 for throttling and expansion. After throttling and expansion, it passes through the fifth refrigerant channel 305 and flows out of the heat exchange integrated module from the fourth interface 334. After the internal evaporator 12, the refrigerant absorbs heat and evaporates, that is, it absorbs heat from the environment, causing the temperature of the passenger compartment to drop. The second flow flows into the third one-way valve 406, and then flows out of the heat exchange integrated module from the second interface 332. It expands through the seventh expansion valve 416 and enters the refrigerator heat exchange module 13 to evaporate and absorb heat, thereby lowering the internal temperature of the refrigerator and completing the refrigerator cooling. Then it returns to the thermal management heat exchange integrated module through the third interface 333. After passing through the second refrigerant channel 302, it merges with the first flow through the eighth interface 338 and enters the gas-liquid separator 20 and compressor 1 for cyclic operation.

[0102] In some other embodiments, such as Figure 6As shown, the thermal management system also includes an air conditioning cooling mode. In this mode, the compressor 1 discharges high-temperature and high-pressure gaseous refrigerant, which enters the external condenser 9. After the refrigerant releases heat and liquefies in the external condenser 9, it becomes a medium-temperature and high-pressure liquid. The refrigerant enters the heat exchange integrated module through the first interface 331, then passes through the second one-way valve 405 and the fourth refrigerant channel 304, and enters the first expansion valve 403 for throttling and expansion. After throttling and expansion, it passes through the fifth refrigerant channel 305 and flows out of the heat exchange integrated module from the fourth interface 334. After passing through the internal evaporator 12, the refrigerant absorbs heat and evaporates, that is, it absorbs heat from the environment, which lowers the temperature of the passenger compartment. Finally, it enters the gas-liquid separator 20 and returns to the compressor 1 for cycle operation.

[0103] Optionally, such as Figure 2 and Figure 20 As shown, the refrigerant passages include a first refrigerant passage 301 and a second refrigerant passage 302; the valve assembly 4 includes a first solenoid valve 401; the second refrigerant passage 302 is connected to the first refrigerant passage 301 through the first solenoid valve 401 to form a first refrigerant flow channel; the first refrigerant passage 301 is adapted to be connected to the compressor 1, and the second refrigerant passage 302 is adapted to be connected to the refrigerator heat exchange module 13.

[0104] In this embodiment, a first refrigerant flow channel is formed by sequentially connecting a second refrigerant channel 302, a first solenoid valve 401, and the first refrigerant channel 301. The first refrigerant channel 301 is connected to the compressor 1, and the second refrigerant channel 302 is adapted to be connected to the refrigerator heat exchange module 13. Thus, by setting the first solenoid valve 401 between the second refrigerant channel 302 and the first refrigerant channel 301, the first solenoid valve 401 controls the on / off state between the second refrigerant channel 302 and the first refrigerant channel 301, thereby achieving switching between various modes.

[0105] Optionally, such as Figure 7As shown, the refrigerant passages also include an eighth refrigerant passage 308, a ninth refrigerant passage 309, a tenth refrigerant passage 310, and an eleventh refrigerant passage 311; the valve assembly 4 includes a third solenoid valve 407, a second expansion valve 409, a third expansion valve 410, a fourth expansion valve 411, and a fifth expansion valve 412; the eighth refrigerant passage 308 is connected to the third refrigerant passage 303 via the second expansion valve 409, and the ninth refrigerant passage 309 is connected to the third refrigerant passage 303 via the third expansion valve 410; the eighth refrigerant passage 308 is adapted to communicate with the refrigerant... The first input end of plate 7 is connected, and the ninth refrigerant channel 309 is adapted to be connected to the second input end of cold plate 7; the tenth refrigerant channel 310 is connected to the second refrigerant channel 302 through the fourth expansion valve 411, the eleventh refrigerant channel 311 is connected to the second refrigerant channel 302 through the fifth expansion valve 412, the tenth refrigerant channel 310 is adapted to be connected to the first output end of cold plate 7, and the eleventh refrigerant channel 311 is adapted to be connected to the second output end of cold plate 7; the seventh refrigerant channel 307 is connected to the second refrigerant channel 302 through the third solenoid valve 407.

[0106] In this embodiment, an eighth refrigerant channel 308 is connected to a third refrigerant channel 303 via a second expansion valve 409, and a ninth refrigerant channel 309 is connected to a third refrigerant channel 303 via a third expansion valve 410. The eighth refrigerant channel 308 is adapted to connect to the first input end of the cold plate 7, and the ninth refrigerant channel 309 is connected to the second input end of the cold plate 7. A tenth refrigerant channel 310 is connected to a second refrigerant channel 302 via a fourth expansion valve 411, and an eleventh refrigerant channel 311 is connected to the second refrigerant channel 302 via a fifth expansion valve 412. The tenth refrigerant channel 310 is connected to the first output end of the cold plate 7, and the eleventh refrigerant channel 311 is adapted to connect to the second output end of the cold plate 7. A seventh refrigerant channel 307 is connected to the second refrigerant channel 302 via a third solenoid valve 407. This facilitates a coordinated mode of refrigerator cooling and battery cooling.

[0107] Specifically, such as Figure 7As shown, the first body 3 is provided with a fifteenth interface 345 and a fourteenth interface 344 that are respectively connected to the eighth refrigerant channel 308 and the ninth refrigerant channel 309. In the refrigerator cooling and battery cooling coordinated mode, the compressor 1 discharges high-temperature and high-pressure gaseous refrigerant. The refrigerant enters the vehicle external condenser 9. After the refrigerant is liquefied by releasing heat in the vehicle external condenser 9, it becomes a medium-temperature and high-pressure liquid. The refrigerant enters the heat exchange integrated module through the first interface 331, and then passes through the second one-way valve 405, the fourth refrigerant channel 304 and the third one-way valve 406. After passing through the third refrigerant channel 303, it is divided into two paths. The first path passes through the second expansion valve 409 and the third expansion valve 410 and enters the eighth refrigerant channel 308 and the ninth refrigerant channel 309 respectively. Then it enters the cold plate 7 through the fifteenth interface 345 and the fourteenth interface 344. At this time, the low-temperature and low-pressure gas-liquid mixture absorbs the heat of the battery and evaporates, thus preventing the power battery temperature from becoming too high. As the temperature drops, the refrigerant enters the heat exchange integrated module through the thirteenth interface 343 and the twelfth interface 342, flows through the eleventh refrigerant channel 311 and the tenth refrigerant channel 310, and then merges in the second refrigerant channel 302 through the fifth expansion valve 412 and the fourth expansion valve 411 respectively. The second path flows out of the heat exchange integrated module from the second interface 332, expands through the seventh expansion valve 416 and enters the refrigerator heat exchange module 13 to evaporate and absorb heat, thereby lowering the internal temperature of the refrigerator and completing the refrigerator's cooling process. Then, after being throttled by the second throttling valve 415, it returns to the thermal management heat exchange integrated module through the third interface 333. Then, it merges with the first path through the second refrigerant channel 302 and enters the gas-liquid separator 20 and the compressor 1 through the eighth interface 338 for cyclic operation.

[0108] Optionally, such as Figure 8 As shown, the refrigerant passages also include a twelfth refrigerant passage 312; the valve assembly 4 also includes a sixth expansion valve 413; one end of the twelfth refrigerant passage 312 is adapted to be connected to the vehicle condenser 8, and the other end is connected to the sixth refrigerant passage 306 through the sixth expansion valve 413.

[0109] In this embodiment, one end of the twelfth refrigerant passage 312 is connected to the vehicle condenser 8, and the other end is connected to the sixth refrigerant passage 306 via the sixth expansion valve 413. This facilitates the implementation of the air conditioning heating mode.

[0110] Specifically, such as Figure 8 As shown, the thermal management system also includes an in-vehicle condenser 8, which is connected to the compressor 1. The first body 3 is provided with an eleventh interface 341 that is connected to the twelfth refrigerant passage 312. The twelfth refrigerant passage 312 is connected to the in-vehicle condenser 8 through the eleventh interface 341.

[0111] In air conditioning heating mode, compressor 1 discharges high-temperature, high-pressure gaseous refrigerant. The refrigerant flows out of compressor 1 and into the vehicle condenser 8, where it releases heat. This heat, combined with the positive temperature coefficient (PTC) heater, is then blown into the vehicle by a blower to heat the interior. The refrigerant from the vehicle condenser 8 enters the twelfth refrigerant passage 312 through the eleventh port 341, undergoes throttling and expansion through the sixth expansion valve 413, and then enters the heat exchanger 2 through the sixth refrigerant passage 306 to absorb heat and evaporate. The refrigerant from the heat exchanger 2 enters the second solenoid valve 404 through the fourth refrigerant passage 304, then exits through the eighth port 338 through the seventh refrigerant passage 307, and finally enters the gas-liquid separator 20 before flowing back into compressor 1 through connecting pipes for continuous operation.

[0112] In some embodiments, such as Figure 9 As shown, the first body 3 also has a thirteenth interface 343 connected to the eleventh refrigerant channel 311 and the tenth refrigerant channel 310. The thermal management system also includes a battery heating mode; in this mode, high-temperature and high-pressure refrigerant flows out from the compressor 1, enters the heat exchange integrated module through the ninth interface 339, flows into the second refrigerant channel 302 after passing through the first refrigerant channel 301 and the first solenoid valve 401, and then flows into the eleventh refrigerant channel 311 and the tenth refrigerant channel 310 after passing through the fifth expansion valve 412 and the fourth expansion valve 411 respectively. It then flows out of the heat exchange integrated module from the thirteenth interface 343 and the twelfth interface 342, passes through the filter screen 22, and then enters the cold plate 7; at this time, the refrigerant condenses and releases heat to heat the battery, thereby heating the battery, improving battery life, improving battery efficiency, increasing battery capacity at low temperatures and the vehicle's driving range, and effectively shortening charging time. After releasing heat, the refrigerant enters the heat exchange integrated module through the fifteenth interface 345 and the fourteenth interface 344. It then enters the eighth refrigerant channel 308 and the ninth refrigerant channel 309, and the second expansion valve 409 and the third expansion valve 410 respectively for throttling and expansion. Subsequently, it merges in the third refrigerant channel 303, and then enters the heat exchanger 2 through the sixth refrigerant channel 306 to absorb heat and evaporate. The refrigerant coming out of the heat exchanger 2 enters the second solenoid valve 404 through the fourth refrigerant channel 304, and then exits from the eighth interface 338 through the seventh refrigerant channel 307. It then enters the gas-liquid separator 20 and enters the compressor 1 through the connecting pipeline for circulation.

[0113] In some embodiments, such as Figure 8 and Figure 9As shown, the thermal management system also includes a battery heating and air conditioning heating coordinated mode. In this mode, high-temperature and high-pressure refrigerant flows out from compressor 1 and enters the heat exchange integration module through the ninth interface 339 and the eleventh interface 341. The refrigerant entering from the eleventh interface 341 forms the first refrigerant flow channel, and the refrigerant entering from the ninth interface 339 forms the second refrigerant flow channel. The first and second refrigerant flow channels merge in the sixth refrigerant channel and enter the heat exchanger 2. The refrigerant coming out of the heat exchanger 2 enters the second solenoid valve 404 through the fourth refrigerant channel 304, then exits from the eighth interface 338 through the seventh refrigerant channel 307, and then enters the gas-liquid separator 20 and enters the compressor 1 through the connecting pipeline for circulation.

[0114] In some embodiments, such as Figure 7 As shown, the thermal management system also includes a battery cooling mode; in this mode, the refrigerant does not flow out from the second interface 332, that is, it does not pass through the refrigerator heat exchange module 13, and all other refrigerants flow through it. Figure 7 Same as above.

[0115] In some embodiments, such as Figure 8 As shown, the thermal management system also includes a defrost mode. In this mode, refrigerant flows out of compressor 1 and into the vehicle condenser 8. The refrigerant releases heat in the vehicle condenser 8, which, in conjunction with the positive temperature coefficient (PTC) heater, blows hot air into the vehicle through a blower to defrost the interior. The refrigerant from the vehicle condenser 8 enters the twelfth refrigerant channel 312 through the eleventh interface 341, and undergoes throttling and expansion through the sixth expansion valve 413. Then, it enters the heat exchanger 2 through the sixth refrigerant channel 306 to absorb heat and evaporate. The refrigerant from the heat exchanger 2 enters the second solenoid valve 404 through the fourth refrigerant channel 304, then flows out from the eighth interface 338 through the seventh refrigerant channel 307, and then enters the gas-liquid separator 20 and enters the compressor 1 through the connecting pipeline for circulation.

[0116] In some embodiments, the thermal management system further includes a battery heating and air conditioning cooling co-processing mode; in this mode, please refer to... Figure 7 and Figure 8High-temperature and high-pressure refrigerant flows out from compressor 1, enters the heat exchange integrated module through the ninth interface 339, flows into the second refrigerant channel 302 after passing through the first refrigerant channel 301 and the first solenoid valve 401, and then flows into the eleventh refrigerant channel 311 and the tenth refrigerant channel 310 after passing through the fifth expansion valve 412 and the fourth expansion valve 411 respectively. It then flows out of the heat exchange integrated module from the thirteenth interface 343 and the twelfth interface 342, passes through the filter screen 22 and then enters the cold plate 7. At this time, the refrigerant condenses and releases heat to heat the battery, thereby improving battery life, improving battery efficiency, increasing battery capacity at low temperatures and the vehicle's driving range, and effectively shortening charging time. After releasing heat, the refrigerant enters the heat exchange integrated module through the fifteenth interface 345 and the fourteenth interface 344, flows out from the fourth refrigerant channel 304, enters the first expansion valve 403 for throttling expansion, passes through the fifth refrigerant channel 305, flows out of the heat exchange integrated module from the fourth interface 334, passes through the vehicle evaporator 12, and absorbs heat to evaporate the refrigerant, that is, absorbs heat from the environment, causing the temperature of the passenger compartment to drop, and finally enters the gas-liquid separator 20 to return to the compressor 1 for cycle operation.

[0117] In some embodiments, the thermal management system further includes a battery cooling and air conditioning cooling coordinated mode. In this mode, such as... Figure 1 As shown, compressor 1 discharges high-temperature, high-pressure gaseous refrigerant, which enters the external condenser 9. In the external condenser 9, the refrigerant releases heat and liquefies, becoming a medium-temperature, high-pressure liquid. The refrigerant enters the heat exchange integrated module through the first interface 331, and then passes through the second one-way valve 405 and the fourth refrigerant channel 304 before splitting into two paths. The first path enters the first expansion valve 403 for throttling and expansion. After throttling and expansion, it passes through the fifth refrigerant channel 305 and flows out of the heat exchange integrated module through the fourth interface 334. After passing through the internal evaporator 12, the refrigerant absorbs heat and evaporates, thus absorbing heat from the environment and lowering the passenger compartment temperature. The second path passes through the third one-way valve 406 into the third refrigerant channel 303, and then through the second expansion valve 409. After passing through the third expansion valve 410, the refrigerant enters the eighth refrigerant channel 308 and the ninth refrigerant channel 309, and then enters the cold plate 7 through the fifteenth interface 345 and the fourteenth interface 344. At this time, the low-temperature and low-pressure gas-liquid mixture absorbs the heat of the battery and evaporates, thereby cooling down the power battery when the temperature is too high. The refrigerant enters the heat exchange integrated module through the thirteenth interface 343 and the twelfth interface 342, flows through the eleventh refrigerant channel 311 and the tenth refrigerant channel 310, and then passes through the fifth expansion valve 412 and the fourth expansion valve 411, flows through the second refrigerant channel, and then flows out of the heat exchange integrated module through the eighth interface 338 to merge with the first path; finally, it enters the gas-liquid separator 20 and returns to the compressor 1 for cyclic operation.

[0118] In some embodiments, the thermal management system further includes a battery cooling and air conditioning heating co-processing mode. In this mode, such as... Figure 1As shown, compressor 1 discharges high-temperature, high-pressure gaseous refrigerant. The refrigerant flows out of compressor 1 and enters the vehicle interior condenser 8. The refrigerant releases heat in the vehicle interior condenser 8, which, in conjunction with a positive temperature coefficient (PTC) heater, heats the interior. The hot air is then blown into the vehicle interior by a blower to provide heating. The refrigerant exiting the vehicle interior condenser 8 enters the twelfth refrigerant passage 312 through the eleventh interface 341, and undergoes throttling and expansion through the sixth expansion valve 413. It then passes through the sixth refrigerant passage 306 and enters the heat exchanger 2 for heat absorption and evaporation. The refrigerant exiting the heat exchanger 2 passes through the fourth refrigerant passage 304 and enters the third one-way valve 406, then the third refrigerant passage 303. After passing through the second expansion valve 409 and the third expansion valve 410, it enters the eighth and ninth refrigerant passages 308 and 309 respectively, and then through the fifteenth interface 345 and the tenth interface... The refrigerant enters the cold plate 7 through the fourth interface 344. At this time, the low-temperature and low-pressure gas-liquid mixture absorbs the heat of the battery and evaporates, thereby cooling down the power battery when the temperature is too high. The refrigerant enters the heat exchange integrated module through the thirteenth interface 343 and the twelfth interface 342, flows through the eleventh refrigerant channel 311 and the tenth refrigerant channel 310, and then passes through the fifth expansion valve 412 and the fourth expansion valve 411 respectively. After flowing through the second refrigerant channel 302, it flows out of the heat exchange integrated module through the eighth interface 338. Finally, it enters the gas-liquid separator 20 and returns to the compressor 1 for cyclic operation.

[0119] Optionally, a first throttle valve 408 is also included; a first throttle valve 408 is also provided on the pipeline connecting the evaporator 12 and the compressor 1 in the vehicle to balance the pressure of the air conditioning branch and the refrigerator branch in the refrigerator cooling and air conditioning cooling coordinated mode.

[0120] In this embodiment, a first throttle valve 408 is positioned between the in-vehicle evaporator 12 and the compressor 1. This balances the pipe pressure at the point of convergence of the two cooling systems in the combined refrigerator and air conditioning cooling mode, facilitating better achievement of the target temperatures corresponding to the refrigerator and air conditioning cooling modes. Furthermore, it extends the service life of the heat exchange integrated module.

[0121] Optionally, such as Figures 1 to 9 As shown, it also includes a first sensor 16; the first sensor 16 is located at one end of the second sub-channel near the heat exchanger 2, and is used to detect the temperature of the refrigerant flowing out of the heat exchanger 2.

[0122] In this embodiment, the first sensor 16 is placed in the second sub-channel near one end of the heat exchanger 2. This allows for the detection of the refrigerant temperature flowing out of the heat exchanger 2, making it easier to adjust the temperature of the refrigerant flowing out of the heat exchanger 2.

[0123] Optionally, such as Figures 10 to 12 , Figures 26 to 33As shown, it also includes a second body 5; the second body 5 is provided with several water-cooling channels; the heat exchanger 2 is also used for heat exchange between the refrigerant in the first body 3 and the coolant in the second body 5.

[0124] Optionally, a portion of the water-cooled channel is used to connect the second output end of the heat exchanger 2 to the power cooling system 11, while another portion of the water-cooled channel is used to connect the second input end of the heat exchanger 2 to the oil cooling plate 6.

[0125] In this embodiment, a plurality of water-cooling channels are provided in the second body 5; some of these channels connect the second output end of the heat exchanger 2 to the power cooling system 11, while others connect the second input end of the heat exchanger 2 to the oil cooling plate heat exchanger 6. The heat exchanger 2 is also used for heat exchange between the refrigerant in the first body 3 and the coolant in the second body 5. Thus, by exchanging heat between the refrigerant in the first body 3 and the coolant in the second body 5, the thermal efficiency is improved.

[0126] In some embodiments of this application, the first body 3 and the second body 5 are detachably connected. This allows for independent assembly and disassembly of the first body 3 and the second body 5, facilitating later maintenance. In some embodiments of this application, the first body 3 and the second body 5 can be connected by a first fastener, which can be a bolt, screw, or stud, etc. In some embodiments of this application, the first body 3 is provided with a first threaded hole, and the first fastener is a screw; the first fastener engages with the first threaded hole to fix the first body 3 and the second body 5.

[0127] In some embodiments, such as Figure 26 As shown, the second body is provided with two tenth interfaces 340, one of which is used to connect to the second input end of the heat exchanger 2, and the other tenth interface 340 is used to connect to the second output end of the heat exchanger 2.

[0128] Optionally, such as Figure 10 , Figures 26 to 33 As shown, it also includes a water pump 14 and a four-way valve 15, which are installed in the second body 5; a plurality of water-cooling channels include a first water-cooling channel 501, a second water-cooling channel 502, a third water-cooling channel 503, and a fourth water-cooling channel 504; one end of the first water-cooling channel 501 is adapted to be connected to the oil cooling plate heat exchanger 6, and the other end is connected to the input end of the water pump 14; one end of the second water-cooling channel 502 is connected to the output end of the water pump 14, and the other end is connected to the second input end of the heat exchanger 2; one end of the third water-cooling channel 503 is connected to the second output end of the heat exchanger 2, and the other end is adapted to be connected to the first input port of the four-way valve 15; one end of the fourth water-cooling channel 504 is connected to the first output port of the four-way valve 15, and the other end is adapted to be connected to the power cooling system 11.

[0129] In this embodiment, one end of the first water-cooling channel 501 is connected to the oil-cooled plate heat exchanger 6, and the other end is connected to the input end of the water pump 14; one end of the second water-cooling channel 502 is connected to the output end of the water pump 14, and the other end is connected to the second input end of the heat exchanger 2; one end of the third water-cooling channel 503 is connected to the second output end of the heat exchanger 2, and the other end is connected to the first input port of the four-way valve 15; one end of the fourth water-cooling channel 504 is connected to the first output port of the four-way valve 15, and the other end is connected to the power cooling system 11. This facilitates the achievement of a heat pump operating mode of -10℃ to 10℃.

[0130] In some embodiments, the thermal management system includes an oil-cooled plate heat exchanger 6 and a power cooling system 11. The second body is also provided with a fifth interface 335 and a seventh interface 337 communicating with the oil-cooled plate heat exchanger 6, and a sixth interface 336 and a seventh interface 337 communicating with the power cooling system 11.

[0131] Specifically, -10℃ to 10℃ refers to an ambient temperature of -10 degrees Celsius to 10 degrees Celsius. In the heat pump operating mode between -10℃ and 10℃, the coolant of the oil-cooled plate heat exchanger 6 enters the water pump 14 through the fifth interface 335, the first water-cooling channel 501, and then enters the heat exchanger 2 through the second water-cooling channel 502. After exchanging heat with the refrigerant in the heat exchanger 2, it enters the four-way valve 15 through the third water-cooling channel 503. After passing through the fourth water-cooling channel 504, the coolant flows out of the integrated valve through the sixth interface 336, flows into the inlet of the power cooling system 11 through the pipeline, and then flows out from the outlet of the power cooling system 11. It then flows back into the inlet of the oil-cooled plate heat exchanger 6 through the pipeline, thus realizing the cyclic operation of the heat pump operating mode between -10℃ and 10℃.

[0132] It should be noted that a seventh interface 337 is provided in the second body 5, and a three-way pipe is provided at the seventh interface 337. The three ports of the three-way pipe are respectively connected to the seventh interface 337, the output port of the power cooling system 11, and the input port of the oil cooling plate heat exchanger 6.

[0133] Optionally, such as Figure 11 As shown, the water cooling channels also include a fifth water cooling channel 505; one end of the fifth water cooling channel 505 is connected to the second output port of the four-way valve 15, and the other end is adapted to be connected to the oil cooling plate 6.

[0134] In some embodiments, one end of the fifth water-cooling channel 505 is connected to the second output port of the four-way valve 15, and the other end is connected to the oil-cooling plate heat exchanger 6. This facilitates the implementation of a heat pump operating mode below -10°C.

[0135] Specifically, such as Figure 11As shown, below -10℃ refers to an ambient temperature below -10 degrees Celsius. In this working mode, the coolant of the oil-cooled plate heat exchanger 6 enters the water pump 14 through the fifth interface 335, the first water-cooling channel 501, and then enters the heat exchanger 2 through the second water-cooling channel 502. After exchanging heat with the refrigerant in the heat exchanger 2, it enters the four-way valve 15 through the third water-cooling channel 503. Then, without passing through the power cooling system 11, the coolant flows back to the input port of the oil-cooled plate heat exchanger 6 through the second output port of the four-way valve 15, thus realizing the heat pump working mode below -10℃.

[0136] In some embodiments, the thermal management system further includes a heat absorption and heat dissipation coordinated working mode. In this mode, the coolant of the oil-cooled plate heat exchanger 6 enters the water pump 14 through the fifth interface 335, through the first water cooling channel 501, and then enters the heat exchanger 2 through the second water cooling channel 502. After exchanging heat with the refrigerant in the heat exchanger 2, it enters the four-way valve 15 through the third water cooling channel 503. The four-way valve 15 controls the water flow, so that the water flow is divided into two paths, one path flows to the power cooling system 11, and the other path flows to the oil-cooled plate heat exchanger 6, realizing the cyclic operation of the heat absorption and heat dissipation working mode.

[0137] Optionally, such as Figure 13 As shown, the second inlet of the four-way valve 15 is connected to the second water-cooling channel 502.

[0138] In this embodiment, the second water-cooling channel 502 is connected to the second inlet of the four-way valve 15. This facilitates a high-temperature heat dissipation mode.

[0139] Specifically, in the high-temperature heat dissipation mode, the coolant of the oil-cooled plate heat exchanger 6 enters the water pump 14 through the fifth interface 335, the first water-cooling channel 501, and then flows directly to the second input port of the four-way valve 15 through the first connection port of the second water-cooling channel 502. It does not enter the heat exchanger 2, but enters the fourth water-cooling channel 504 and then flows out of the heat exchange integration module through the sixth interface 336 and enters the power heat dissipation system 11, thus realizing the cyclic operation of the high-temperature heat dissipation mode.

[0140] Optionally, such as Figures 14 to 16 As shown, the first body 3 and the second body 5 are stacked; the heat exchanger 2 is located on the side of the first body 3 away from the second body 5.

[0141] In this embodiment, the first body 3 and the second body 5 are stacked; the heat exchanger 2 is located on the side of the first body 3 opposite to the second body 5. This simplifies the structure of the heat exchange integrated module, making the structure simpler and more compact compared to using a large number of intertwined pipes. Furthermore, the stacked arrangement of the first body 3 and the second body 5, with the heat exchanger 2 located on the side of the first body 3 opposite to the second body 5, results in a more compact arrangement of the first body 3, the second body 5, and the heat exchanger 2, reducing the space required. Therefore, the heat exchange integrated module provided by this application improves structural compactness.

[0142] Moreover, compared to using a lot of intertwined pipelines, the first body 3 and the second body 5 in this application are structurally more independent, with less mutual influence, and are easy to disassemble and assemble. When disassembling or assembling one of the first body 3 and the second body 5, it is not easy to have a significant impact on the installation status of the other, which is conducive to improving the efficiency of vehicle maintenance in the later stage.

[0143] Of course, in some embodiments of this application, the first body 3 and the second body 5 may also be connected together by snap-fitting, welding or bonding.

[0144] In some embodiments, both the first body 3 and the second body 5 are connected to the heat exchanger 2, allowing the fluid from the first body 3 and the fluid from the second body 5 to exchange heat within the heat exchanger 2. The fluid from the first body 3 and the fluid from the second body 5 flow through two isolated flow channels within the heat exchanger 2. In this application, the first body 3 and the second body 5 can be connected to the heat exchanger 2 via sealing rings, which helps improve sealing performance.

[0145] In some embodiments, such as Figures 1 to 13 As shown, the compressor 1 can be connected to the heat exchanger 2 and other components through the corresponding interface on the first body 3, so that the compressor 1 and other components can work together to realize functions such as refrigerator cooling, heater heating, air conditioning cooling and heating, vehicle battery heating and cooling, and vehicle glass defrosting.

[0146] In some embodiments, such as Figure 16 As shown, it also includes a connecting plate 19; the first body 3 and the connecting plate 19 can be welded together, for example, by brazing. This results in a high level of sealing between the first body 3 and the connecting plate 19, which is beneficial for both excellent sealing and burst resistance. Similarly, the second body 5 and the connecting plate 19 can also be welded together, for example, by brazing. This also results in a high level of sealing between the second body 5 and the connecting plate 19, which is beneficial for both excellent sealing and burst resistance.

[0147] Optionally, such as Figure 17As shown, the first body 3 has several first mounting holes 31 communicating with the refrigerant channel on the side opposite to the second body 5; the valve assembly 4 includes several valves, each valve being installed in a corresponding first mounting hole 31.

[0148] In this embodiment, a plurality of first mounting holes 31 communicating with refrigerant channels are provided on the side of the first body 3 away from the second body 5, and each valve is installed in one of the first mounting holes 31. This facilitates the installation of the valves.

[0149] It should be noted that the valves mentioned here can refer to various expansion valves, solenoid valves, check valves, and throttle valves in the above embodiments.

[0150] Furthermore, such as Figure 15 and Figure 16 As shown, each valve is connected together by a wiring harness 23, which is connected to the first body 3 and the second body 5 by a snap fastener, thus facilitating the integrated layout of the entire vehicle.

[0151] In some embodiments, the first body 3 includes a first sub-plate 32 and a second sub-plate 33; the first sub-plate 32 is provided with a plurality of first mounting holes 31; each mounting hole is used to install a corresponding valve. The valve may be provided with a first external thread, the axial direction of the first external thread is the same as the axial direction of the first mounting hole 31, and the valve can be installed in the first mounting hole 31 through the first external thread.

[0152] In some embodiments, a heat insulation cavity is formed on the first body 3, which is isolated from each refrigerant channel and located between two adjacent refrigerant channels. This heat insulation cavity between adjacent refrigerant channels prevents heat transfer, thus improving heat utilization. In some embodiments of this application, a heat insulation cavity may also be provided on the second body 5.

[0153] In some embodiments, such as Figures 21 to 25 As shown, the refrigerant flow channel can be formed by drilling holes in the first sub-plate 32. During the drilling process, the axis of the drill bit is the extension direction of the first part. After drilling to form a hole structure, the openings at one or both ends of the hole structure can be sealed with sealing caps 24 to form a refrigerant flow channel. In some embodiments of this application, the sealing caps 24 can be installed at the openings of the hole structure by welding, such as brazing.

[0154] In some embodiments, such as Figure 18As shown, the first sub-plate 32 is provided with a sixteenth interface 346 and a seventeenth interface 347; the sixteenth interface 346 is located below the seventeenth interface 347, and the sixteenth interface 346 is connected to the first input end of the heat exchanger 2, while the seventeenth interface 347 is connected to the first output end of the heat exchanger 2. In this way, after the refrigerant enters the heat exchanger 2 through the sixteenth interface 346, it flows upward and re-enters the first body 3 through the seventeenth interface 347; this bottom-in, top-out flow pattern is beneficial for improving heat exchange efficiency. In some embodiments of this application, the heat exchange efficiency can be increased by approximately 30% to 40% compared to downward flow.

[0155] In some embodiments, such as Figures 1 to 9 , Figures 21 to 25 As shown, the diameters of the eighth refrigerant channel 308 and the ninth refrigerant channel 309 are 8mm, the diameter of the eleventh refrigerant channel 311 is 16mm, the diameter of the eleventh refrigerant channel 311 is 12mm, the cross-sectional area of ​​the flow channel of the third refrigerant channel 303 is 8mm*13.5mm, the cross-sectional area of ​​the flow channels of the first refrigerant channel 301, the fourth refrigerant channel 304 and the sixth refrigerant channel 306 is 12mm*12mm, and the cross-sectional area of ​​the flow channels of the second refrigerant channel 302, the seventh refrigerant channel 307 and the tenth refrigerant channel 310 is 16mm*13.5mm. This helps to reduce flow resistance.

This is beneficial to improving the stability and convenience of installing the valve on the first mounting hole 31. In the embodiments of this application, at least one of an expansion valve, a throttle valve, a solenoid valve, and a check valve can be mounted on the first mounting hole 31 using the valve mounting base 10.

[0157] In some embodiments of this application, the number of snap-fit ​​structures can be at least two, and the snap-fit ​​structures are arranged circumferentially along the first mounting hole 31, and can be evenly arranged. This helps to improve the stability of valve installation. Of course, in some embodiments of this application, the number of snap-fit ​​structures can be only one.

[0158] In some embodiments, such as Figure 19 As shown, a stop protrusion 104 is formed in the middle of the extension direction of the snap-fit ​​structure 101. The protrusion direction of the stop protrusion 104 is perpendicular to the orientation of the first mounting hole 31. The stop protrusion 104 is supported on the first body 3 along the orientation of the first mounting hole 31 to limit the displacement of the snap-fit ​​structure along the first mounting hole 31.

[0159] In some embodiments, such as Figure 19 As shown, the mounting base body 103 is also provided with an elastic support structure 102; the elastic support structure 102 at least partially abuts against the wall of the first mounting hole 31. This helps to improve the stability of the valve mounted on the first body 3. Of course, in some embodiments of this application, the number of elastic support structures 102 can be one.

[0160] In some embodiments, such as Figure 19 As shown, at least two elastic support structures 102 are provided; at least two elastic support structures 102 are arranged circumferentially around the mounting body 103. This is to further enhance the stability of the valve when mounted on the first body 3.

This facilitates accurate detection of the temperature of the coolant in the second water-cooling channel 502.

[0172] In some embodiments, such as Figure 28 and Figure 29 As shown, a fourth mounting hole 54 is provided in the fourth sub-plate 56. The fourth mounting hole 54 is connected to the second water cooling channel 502 and is used to install the second sensor 17.
