[0029] Referring to Figures 4 to 6The block portion 11 has a first hole 111, a second hole 112, a third hole 113, and a first mounting hole 117. The first hole 111 and the second hole 112 are isolated from each other in the block portion 11.

In this embodiment, the first port is farther away from the bottom side than the second port.

[0030] The block portion 11 includes a groove portion 116 which is formed by inwardly recessing a part of the rear side surface. The groove portion 116 has a groove opening toward the first heat exchanger 5, and in the present embodiment, the edge of the groove opening of the groove portion 116 is sealingly connected to the first surface 57 of the first heat exchanger 5. In other words, the groove cavity of the groove portion 116 includes a space between the first surface 57 of the first heat exchanger 5, the side wall of the groove portion 116, and the bottom wall of the groove portion 116.

The end of the cover portion 92 away from the cavity portion 91 is fixedly connected with the block portion 11. The cover portion 92 has two through holes in communication with the inner cavity of the cavity portion 91. One of the two through holes is in communication with the fourth hole 114, and the other is in communication with the fifth hole 115. One of the two through holes serves as the inlet of the drying device 9, and the other serves as the outlet of the drying device 9. After flowing through the drying device 9, the fluid can be dried and part of the impurities can be filtered out. The opening of the fifth hole 115 on the back surface is arranged opposite to the opening of the second hole section 54 on the first surface 57.

[0043] The thermal management system provided by the embodiment of the present application can be applied to an electric vehicle. The electric vehicle has an air conditioning box 200 for heat exchange with air in a passenger cabin. The indoor condenser 2 and the indoor evaporator 3 are arranged in the air conditioning box 200 and are used for heat exchange with air in the air conditioning box 200 to adjust the temperature of the passenger cabin. The indoor condenser 2 is located on the downstream side of the air flow relative to the indoor evaporator 3. The air conditioning box 200 is provided with a fan and an air door. The fan is used for guiding the flow of air in the air conditioning box 200, and the air door is used for controlling the amount of air flowing through the indoor condenser 2. In the cooling mode, the air door is closed, and the indoor condenser 2 does not participate in heat exchange. The outdoor heat exchanger 4 and the low-temperature water tank are arranged near the front air grille of the vehicle. The outdoor heat exchanger 4 and the low-temperature water tank are used for heat exchange with the atmosphere and are used for releasing heat to the atmosphere or absorbing heat from the atmosphere. A fan device is arranged for guiding the flow of air. The indoor condenser 2, the indoor evaporator 3, the outdoor heat exchanger 4 and the low-temperature water tank are all air-cooled heat exchangers and are used for heat exchange with air. The structure of the air-cooled heat exchanger is well known to those skilled in the art, and will not be described herein.

[0044] The thermal management system has multiple working modes, including a heating mode and a cooling mode. In the embodiment of the present application, Figure 7 for an embodiment of the cooling mode of the thermal management system, Figure 8For an embodiment of the heating mode of the heat management system, the thick solid line indicates that the refrigerant circulates, the arrow indicates the flow direction of the refrigerant, and the gray dashed line indicates that the refrigerant does not circulate. The heat management system of this embodiment is not only suitable for vehicles but also suitable for other heat exchange systems that require heat management. For ease of description, the description of the present application is described by taking the application to a vehicle as an example.

[0045] With reference to Figure 7 In the cooling mode, the first valve 83 is closed, the second valve 84 is open, the third valve 81 and the fourth valve 82 are throttled, and the multi-way device 7 is in the first state. The first interface 71 and the second interface 72 are in communication, and the third interface 73 and the fourth interface 74 are in communication. The outlet of the compressor 1, the multi-way device 7, the outdoor heat exchanger 4, the second valve 84, the drying device 9, the first heat exchange part 51, the third valve 81, the indoor evaporator 3, the gas-liquid separator 10, the second heat exchange part 52, and the inlet of the compressor 1 are sequentially communicated. In addition, the outlet of the compressor 1, the multi-way device 7, the outdoor heat exchanger 4, the second valve 84, the drying device 9, the first heat exchange part 51, the fourth valve 82, the third heat exchange part 61, the gas-liquid separator 10, the second heat exchange part 52, and the inlet of the compressor 1 are sequentially communicated. Two refrigerants exchange heat in the first heat exchanger 5, and the refrigerant and the cooling liquid exchange heat through the second heat exchanger 6.

[0046] Specifically, the refrigerant from the compressor 1 flows to the outdoor heat exchanger 4 through the multi-way device 7, and releases heat to the atmosphere at the outdoor heat exchanger 4, and the temperature of the refrigerant is lowered. The outlet of the outdoor heat exchanger 4 is communicated with the third hole 113 of the fluid management assembly 100, at this time, the first valve 83 and the fifth valve 85 are closed, and the second valve 84 is open, 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 channel 54 and the fourth channel 55 in turn, and then flows out of the fluid management assembly 100 from the fourth channel 55. The refrigerant flowing out of the fourth channel 55 is divided into two paths, one path flows into the indoor evaporator 3 after throttling by the third valve 81, to achieve cooling of the passenger cabin, and the other path flows into the third heat exchange part 61 after throttling by the fourth valve 82, to achieve cooling of the cooling liquid, which can be used for cooling of the battery or the motor. The refrigerant flowing out of the indoor evaporator 3 and the refrigerant flowing out of the third heat exchange part 61 converge into the gas-liquid separator 10, 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 is communicated with the third channel 56 of the fluid management assembly 100, in the fluid management assembly 100, the refrigerant flows through the third channel 56, the first channel 53, the groove cavity of the groove part 116 and the first hole 111 in turn, 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 part 51 exchanges heat with the low-temperature refrigerant in the second heat exchange part 52, to improve the system performance. The refrigerant flowing out of the first hole 111 flows to the inlet of the compressor 1, the compressor 1 re-compresses the refrigerant, and the cycle continues.

[0047] It needs to be understood that when the fifth valve 85 is a one-way valve, although the refrigerant can flow on both sides of the fifth valve 85, the high-pressure refrigerant before throttling flows in the fourth hole 114, and the low-pressure refrigerant after throttling flows on the other side of the fifth valve 85, due to the pressure difference, the fifth valve 85 will not be open, and there will be no cross-flow phenomenon. When the fifth valve 85 is a stop valve or an electronic expansion valve, the fifth valve 85 is in a closed state.

[0048] In other refrigeration modes, the fourth valve 82 is closed, the refrigerant does not exchange heat with the cooling liquid, and only the cooling of the passenger cabin is achieved. Alternatively, the third valve 81 is closed, and there is no heat exchange in the passenger cabin, and only the cooling of the cooling liquid is achieved, which can be used for cooling of the motor or the battery.

[0049] Reference Figure 8In the heating mode, the second valve 84 and the third valve 81 are closed, the fifth valve 85 is open, the first valve 83 and the fourth valve 82 are throttled, and the multi-way device 7 is in the second state, the first port 71 communicates with the fourth port 74, and the second port 72 communicates with the third port 73. The outlet of the compressor 1, the multi-way device 7, the indoor condenser 2, the fifth valve 85, the drying device 9, the first heat exchange part 51, the first valve 83, the outdoor heat exchanger 4, the multi-way device 7, the gas-liquid separator 10, the second heat exchange part 52, and the inlet of the compressor 1 are sequentially communicated, and the outlet of the compressor 1, the multi-way device 7, the indoor condenser 2, the fifth valve 85, the drying device 9, the first heat exchange part 51, the fourth valve 82, the third heat exchange part 61, the multi-way device 7, the gas-liquid separator 10, the second heat exchange part 52, and the inlet of the compressor 1 are sequentially communicated, and the two refrigerant flows exchange heat in the first heat exchanger 5, and the refrigerant and the cooling liquid exchange heat through the second heat exchanger 6.

[0050] Specifically, the refrigerant flowing out of the compressor 1 flows to the indoor condenser 2 through the multi-way device 7, exchanges heat with the cabin air at the indoor condenser 2, and realizes the heating of the passenger cabin. At this time, the second valve 84 is closed, and the fifth valve 85 is open. The outlet of the indoor condenser 2 communicates with the fourth hole 114 of the fluid management assembly 100. In the fluid management assembly 100, the refrigerant sequentially flows through the fourth hole 114, the drying device 9, the fifth hole 115, the second hole 54, and the fourth hole 55. The refrigerant flowing out of the fourth hole 55 is divided into two flows, one of which flows to the lumen of the communication pipe 12, throttles through the first valve 83, and then flows out of the fluid management assembly 100 from the third hole 113, and the other directly flows out of the fluid management assembly 100 from the fourth hole 55. The refrigerant flowing out of the third hole 113 flows to the outdoor heat exchanger 4, and absorbs heat from the atmosphere at the outdoor heat exchanger 4. The refrigerant directly flowing out of the fourth hole 55 flows to the fourth valve 82, throttles through the fourth valve 82, and then flows into the third heat exchange part 61. The refrigerant can be used for waste heat recovery of the battery and / or motor by absorbing heat from the cooling liquid. The refrigerant flowing out of the outdoor heat exchanger 4 flows to the inlet of the gas-liquid separator 10 through the multi-way device 7, and the refrigerant flowing out of the third heat exchange part 61 also flows to the inlet of the gas-liquid separator 10. 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 hole 56 of the fluid management assembly 100. In the fluid management assembly 100, the refrigerant sequentially flows through the third hole 56, the first hole 53, the groove cavity of the groove part 116, and the first hole 111, 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 part 51 exchanges heat with the low-temperature refrigerant in the second heat exchange part 52, thereby improving the system performance. The refrigerant flowing out of the first hole 111 flows to the inlet of the compressor 1, the compressor 1 re-compresses the refrigerant, and the cycle continues.

[0051] It should be understood that although the two sides of the second valve 84 have refrigerant flowing, the fourth hole 114 flows high-pressure refrigerant before throttling, and the third hole 113 flows low-pressure refrigerant after throttling. Due to the pressure difference, the second mounting hole 118 is not in communication with the third hole 113, and there is no cross-flow phenomenon.

[0052] In other heating modes, the fourth valve 82 is closed, the refrigerant does not exchange heat with the coolant, and only absorbs heat from the atmosphere. Alternatively, the first valve 83 is closed, and there is no heat exchange at the outdoor heat exchanger 4, and heat is obtained from the coolant, which can achieve waste heat recovery of the motor and / or battery. Alternatively, the third valve 81 throttles, and the refrigerant flowing out of the fourth hole 55 is divided into two paths, one of which flows into the indoor evaporator 3 after throttling by the third valve 81, achieving passenger compartment heating and dehumidification, and the other of which flows into the third heat exchange part 61 after throttling by the fourth valve 82, achieving waste heat recovery of the motor and / or battery. The refrigerant flowing out of the indoor evaporator 3 also flows to the inlet of the gas-liquid separator 10.

The two components can only have a pipeline therebetween, or a valve or other component can be provided therebetween in addition to the pipeline. Similarly, the "communication" between two components in the present application can be direct communication or communication through a pipeline.

Although the present application has been disclosed as above, it is not intended to limit the present application.
