The thermal management system of the present embodiment is not only suitable for vehicles, but also suitable for other heat exchange systems requiring thermal management, and for convenience of description, the description of the present application will be given by taking application to vehicles as an example.

Referring to fig. 7, in the cooling mode, the first valve element 83 is turned off, the second valve element 84 is turned on, the third valve element 81 and the fourth valve element 82 are throttled, the multi-way device 7 is in the first state, the first port 71 communicates with the second port 72, and the third port 73 communicates with the fourth port 74. The outlet of the compressor 1, the multi-pass device 7, the outdoor heat exchanger 4, the second valve element 84, the drying device 9, the first heat exchanging portion 51, the third valve element 81, the indoor evaporator 3, the gas-liquid separator 10, the second heat exchanging portion 52, and the inlet of the compressor 1 are sequentially communicated, and the outlet of the compressor 1, the multi-pass device 7, the outdoor heat exchanger 4, the second valve element 84, the drying device 9, the first heat exchanging portion 51, the fourth valve element 82, the third heat exchanging portion 61, the gas-liquid separator 10, the second heat exchanging portion 52, and the inlet of the compressor 1 are sequentially communicated, the two refrigerants exchange heat in the first heat exchanger 5, and the refrigerant exchanges heat with the cooling liquid through the second heat exchanger 6.

Specifically, the refrigerant flowing out of the compressor 1 flows through the multi-pass device 7 to the outdoor heat exchanger 4, and releases heat to the atmosphere at the outdoor heat exchanger 4, thereby lowering the temperature of the refrigerant. The outlet of the outdoor heat exchanger 4 communicates with the third hole 113 of the fluid management assembly 100, at which time the first valve element 83 and the fifth valve element 85 are closed, the second valve element 84 is opened, and in the fluid management assembly 100, the refrigerant flows through the third hole 113, the second mounting hole 118, the fourth hole 114, the drying device 9, the fifth hole 115, the second orifice 54, and the fourth orifice 55 in this order, and then flows out of the fluid management assembly 100 from the fourth orifice 55.

The refrigerant flowing out of the indoor evaporator 3 and the refrigerant flowing out of the third heat exchange portion 61 are merged into the gas-liquid separator 10, and after gas-liquid separation, the liquid refrigerant is stored in the gas-liquid separator 10, and the gaseous refrigerant flows out of the gas-liquid separator 10. The outlet of the gas-liquid separator 10 communicates with the third port 56 of the fluid management assembly 100, and within the fluid management assembly 100, the refrigerant flows through the third port 56, the first port 53, the groove cavity of the groove 116, and the first hole 111 in that order, and then flows out of the fluid management assembly 100 from the first hole 111. In the first heat exchanger 5, the high-temperature refrigerant in the first heat exchange portion 51 exchanges heat with the low-temperature refrigerant in the second heat exchange portion 52, thereby improving system performance. The refrigerant flowing out of the first hole 111 flows to the inlet of the compressor 1, and the compressor 1 recompresses the refrigerant, thus circulating.

It should be understood that when the fifth valve element 85 is a check valve, although the refrigerant can flow on both sides of the fifth valve element 85, the high-pressure refrigerant before throttling flows in the fourth hole 114, the low-pressure refrigerant after throttling flows on the other side of the fifth valve element 85, and the fifth valve element 85 is not conducted and does not have a series flow phenomenon due to the pressure difference. When the fifth valve element 85 is a shut-off valve or an electronic expansion valve, the fifth valve element 85 is in a shut-off state.

Specifically, the refrigerant flowing out of the compressor 1 flows to the indoor condenser 2 through the multi-pass device 7, and exchanges heat with the passenger compartment air at the indoor condenser 2, thereby realizing passenger compartment heating. At this time, the second valve element 84 is closed, the fifth valve element 85 is open, and the outlet of the indoor condenser 2 communicates with the fourth orifice 114 of the fluid management assembly 100. Within the fluid management assembly 100, the refrigerant flows through the fourth orifice 114, the drying device 9, the fifth orifice 115, the second orifice 54, and the fourth orifice 55 in that order. The refrigerant flowing out of the fourth orifice 55 is split into two paths, one of which flows into the lumen of the communication pipe 12, throttled by the first valve element 83, and then flows out of the fluid management assembly 100 through the third orifice 113, and the other of which directly flows out of the fluid management assembly 100 through the fourth orifice 55. The refrigerant flowing out of the third hole 113 flows to the outdoor heat exchanger 4, and absorbs heat of the atmosphere at the outdoor heat exchanger 4. The refrigerant directly flowing out of the fourth orifice 55 flows to the fourth valve element 82, is throttled by the fourth valve element 82, flows into the third heat exchanging portion 61, and obtains heat from the cooling liquid, thereby being capable of being used for waste heat recovery of the battery and/or the motor. The refrigerant flowing out of the outdoor heat exchanger 4 flows through the multi-pass device 7 to the inlet of the gas-liquid separator 10, the refrigerant flowing out of the third heat exchange portion 61 also flows to the inlet of the gas-liquid separator 10, the liquid refrigerant is stored in the gas-liquid separator 10 after gas-liquid separation, and the gaseous refrigerant flows out of the gas-liquid separator 10. The outlet of the gas-liquid separator 10 communicates with the third port 56 of the fluid management assembly 100, and within the fluid management assembly 100, the refrigerant flows through the third port 56, the first port 53, the groove cavity of the groove 116, and the first hole 111 in that order, and then flows out of the fluid management assembly 100 from the first hole 111. In the first heat exchanger 5, the high-temperature refrigerant in the first heat exchange portion 51 exchanges heat with the low-temperature refrigerant in the second heat exchange portion 52, thereby improving system performance. The refrigerant flowing out of the first hole 111 flows to the inlet of the compressor 1, and the compressor 1 recompresses the refrigerant, thus circulating.

It should be understood that although the refrigerant flows on both sides of the second valve member 84, the high-pressure refrigerant before throttling flows in the fourth hole 114, the low-pressure refrigerant after throttling flows in the third hole 113, and the second mounting hole 118 is not communicated with the third hole 113 due to the pressure difference, so that no series flow phenomenon occurs.

In the other heating mode, the fourth valve element 82 is closed, and the refrigerant does not exchange heat with the coolant, and absorbs heat only from the atmosphere. Alternatively, the first valve member 83 is closed, no heat exchange is performed at the outdoor heat exchanger 4, and heat is obtained from the cooling liquid, so that waste heat recovery of the motor and/or the battery can be realized. Or, the third valve element 81 throttles, the refrigerant flowing out of the fourth hole 55 is divided into two paths, one path is throttled by the third valve element 81 and flows into the indoor evaporator 3 to realize heating and dehumidification of the passenger cabin, the other path is throttled by the fourth valve element 82 and flows into the third heat exchange part 61 to realize waste heat recovery of the motor and/or the battery, and the refrigerant flowing out of the indoor evaporator 3 also flows to the inlet of the gas-liquid separator 10.
