[0034] One embodiment of the present invention further provides a thermal management system, comprising a compressor 1, a fluid management device 10, a first heat exchanger 2, and a second heat exchanger 3. The compressor 1 has an outlet 11, a first inlet 12, and a second inlet 13. The first inlet 12 is a relatively high-pressure inlet, and the second inlet 13 is a relatively low-pressure inlet. Specifically, the outlet of the compressor 1 is connected to the fifth port 1005, one port of the first heat exchanger 2 is connected to the second port 1002, and another port of the first heat exchanger 2 is connected to the first port 1001, or in other words, the second port 1002 can be connected to the first port 1001 through the first heat exchanger 2, the third port 1003 is connected to the first inlet 12 of the compressor 1, one port of the second heat exchanger 3 is connected to the fourth port 1004, and another port of the second heat exchanger 3 is connected to the seventh port 1007, or in other words, the fourth port 1004 can be connected to the seventh port 1007 through the second heat exchanger 3, and the sixth port 1006 is connected to the second inlet 13 of the compressor 1. The compressor 1, the first heat exchanger 2, and the second heat exchanger 3 respectively have ports connected to the fluid management device 10, or in other words, the thermal management system is connected to the compressor 1, the first heat exchanger 2, and the second heat exchanger 3 through the fluid management device 10. The connection relationship of the thermal management system is relatively simple and can also reduce the installation steps.

[0035] In this embodiment, the first heat exchanger 2 is located in the vehicle's front-end module and is used for heat exchange with ambient air, absorbing heat from the ambient air or releasing heat to the ambient air. The second heat exchanger 3 is located in the air conditioning unit and is used to regulate the temperature of the passenger compartment. The thermal management system also includes a radiator and a first pump. The second flow channel of the first heat exchange module 120 and the first pump are connected in series with the radiator, which is located in the air conditioning unit and regulates the temperature of the passenger compartment. The thermal management system also includes a second pump and a battery cooler. The second flow channel of the second heat exchange module 110 and the second pump are connected in series with the battery cooler, which regulates the temperature of the battery.

[0036] The thermal management system includes a heating mode and a cooling mode. In the heating mode, the fluid management device 10 is in a first working mode. Specifically, the high-temperature and high-pressure refrigerant releases heat in the first heat exchange module 120, and then the refrigerant enters the first valve chamber 3133 of the first fluid management module 310 through the first connecting channel 250 of the connector 200. The first valve core 313 connects the first throttling chamber 3131' to the first valve chamber 3133 and the first gas-liquid separation chamber 3161. After the throttling and pressure reduction of the refrigerant is separated into gas and liquid in the first gas-liquid separation chamber 3161, the relatively gaseous refrigerant enters the first inlet 12 of the compressor 1 through the third port 1003, and the relatively liquid refrigerant enters the first heat exchanger 2 through the second port 1002 and evaporates and absorbs heat in the first heat exchanger 2. The refrigerant flowing out of the first heat exchanger 2 enters the first port 1001 of the fluid management device 10, and the valve unit 400 opens the third sub-channel 263. The refrigerant enters the gas separation chamber through the second sub-channel 262 and enters the second inlet 13 of the compressor 1 from the sixth port 1006 to participate in the next cycle. After the throttled refrigerant is separated into gas and liquid in the first gas-liquid separator, it enters the compressor 1 in a relatively gaseous state. This has the effect of increasing the gas and replenishing the heat for the entire thermal management system, thereby improving the performance of the thermal management system. In the cooling mode, the fluid management device 10 is in the second operating mode. The high-temperature and high-pressure refrigerant discharged from the compressor 1 enters the first valve chamber 3133 of the first fluid management module 310 through the first heat exchange module 120 and the first connecting channel 250. The first valve core 313 connects the first conducting channel 3132 to the first valve chamber 3133 and the second port 1002. The high-temperature and high-pressure refrigerant releases heat in the first heat exchanger 2, and then enters the second sub-channel 262 of the connector 200 through the first port 1001. Then it enters the second valve chamber 3153. The second valve core 315 connects the second throttling chamber 3151' to the second valve chamber 3153 and the second gas-liquid separation chamber 3171. The relatively gaseous refrigerant enters the first inlet 12 of the compressor 1 through the third port 1003, and the relatively liquid refrigerant enters the second heat exchanger 3 through the fourth port 1004 and evaporates and absorbs heat in the second heat exchanger 3. The refrigerant enters the gas separation chamber through the seventh port 1007, and then enters the second inlet 13 of the compressor 1 through the sixth port 1006 to participate in the next cycle. After the throttled refrigerant is separated into gas and liquid in the second gas-liquid separation chamber, the relatively gaseous refrigerant enters the compressor 1. This has the effect of increasing gas and replenishing enthalpy for the entire thermal management system, which can improve the performance of the thermal management system. It can be seen that the thermal management system of this embodiment has the effect of increasing gas and replenishing enthalpy in both cooling mode and heating mode, and the performance of the thermal management system is improved.

[0037] In addition, the thermal management system also includes a battery cooling mode. In the battery cooling mode, the fluid management device 10 is in the second working mode. The high-temperature and high-pressure refrigerant discharged from the compressor 1 enters the first valve chamber 3133 of the first fluid management module 310 through the first heat exchange module 120 and the first connecting channel 250. The first valve core 313 connects the first conducting channel 3132 to the first valve chamber 3133 and the second port 1002. The high-temperature and high-pressure refrigerant releases heat in the first heat exchanger 2, and then the refrigerant enters the connecting piece 200 through the first port 1001. At this time, the valve unit 400 closes the third sub-channel 263, and the second valve core 315 connects the second throttling chamber 3151' to the second valve chamber 3153 and the second gas-liquid In the separation chamber 3171, the relatively gaseous refrigerant enters the first inlet 12 of the compressor 1 through the third port 1003, while the relatively liquid refrigerant enters the second heat exchanger 3 through the fourth port 1004, where it evaporates and absorbs heat. The refrigerant then enters the gas separation chamber through the seventh port 1007 and then enters the second inlet 13 of the compressor 1 through the sixth port 1006, participating in the next cycle. The throttling unit 500 opens, throttling and reducing the pressure of the refrigerant, which then enters the second heat exchange module 110, where it evaporates and absorbs heat. The refrigerant then enters the gas separation chamber through the third connecting channel 270 and then enters the second inlet 13 of the compressor 1 through the sixth port 1006, participating in the next cycle. In other embodiments, the second valve core 315 disconnects the second valve chamber 3153 from the fourth port 1004, and the second valve core 315 disconnects the second valve chamber 3153 from the second gas-liquid separation chamber 3171. In this case, the second heat exchanger 3 does not participate in heat exchange.
