Further, a sealing arrangement can be provided between the pressure relief valve 3 and the receiving part, which is beneficial to prevent fluid leakage from the assembly gap between the pressure relief valve 3 and the receiving part. The pressure relief valve 3 is mainly used to open and release pressure when the pressure of the working fluid in the passage (especially the pressure of the working fluid in the fourth passage 54) is higher than a certain value, which is beneficial to ensure that the pressure in the passage is not overloaded.

[0020] Referring to Figure 1 and Figure 2 , the thermal management assembly 100 further comprises a gas-liquid separation element 6, which mainly separates gas-liquid two-phase.

The temperature and pressure sensor 7 is arranged to determine whether the superheat degree of the working fluid flowing from the fifth channel 55 into the gas-liquid separation element 6 meets the requirements, so as to ensure that the working fluid flowing from the fifth channel 55 into the gas-liquid separation element 6 is full-gas-phase working fluid after gas-liquid separation, and then enters the compressor from the first interface 61, thereby ensuring the safe operation of the compressor in the thermal management system.

[0022] Referring to Figure 4 and Figure 5 , when the thermal management assembly 100 is applied to the thermal management system, it includes but is not limited to two working modes:

[0023] Referring to Figure 3 and Figure 4 , the first working mode of the thermal management assembly 100 when applied to the thermal management system: the first switch valve element 21 and the third switch valve element 23 are closed, and the second switch valve element 22 and the first throttle valve element 31 are opened, at this time, the first channel 51 is in communication with the third channel 53 through the second switch valve element 22, and the seventh channel 57 is in communication with the sixth channel 56 through the first throttle valve element 31.

[0024] At this time, the high-temperature and high-pressure working fluid (such as refrigerant) at the outlet side of the compressor 200 flows from the first port 510 into the first channel 51, flows into the third channel 53 through the second switch valve element 22, and flows out from the third port 530 to the outdoor heat exchanger 201, becomes a relatively high-temperature and high-pressure working fluid (at this time, the working fluid is in a gas-liquid two-phase state, and the relatively high temperature is lower than the high temperature) after heat exchange and heat dissipation in the outdoor heat exchanger 201, enters the gas-liquid separation element 6 through the second interface 62, and after gas-liquid two-phase separation in the gas-liquid separation element 6, the gaseous working fluid flows back to the compressor 200 through the first interface 61, and the liquid working fluid enters the seventh channel 57 through the fourth interface 64, and becomes a low-temperature and low-pressure working fluid after throttling in the first throttling valve element 31, and flows to the sixth channel 56, part of the low-temperature and low-pressure working fluid in the sixth channel 56 flows to the indoor heat exchanger 202 through the seventh port 560, becomes a relatively low-temperature and low-pressure working fluid (at this time, the working fluid is in a gas-liquid two-phase state, and the relatively low temperature is higher than the low temperature) after heat exchange and heat absorption in the indoor heat exchanger 202, flows into the fourth channel 54 through the fourth port 540 (at this time, the fourth switch valve element 24 on the flow path is opened), and flows back to the gas-liquid separation element 6 through the third interface 63 for recirculation; another part of the low-temperature and low-pressure working fluid in the sixth channel 56 flows to the plate heat exchanger 203 through the eighth port 561, becomes a relatively low-temperature and low-pressure working fluid (gas-liquid two-phase state) after heat exchange and heat absorption in the plate heat exchanger, flows into the fifth channel 55 through the fifth port 550, and also flows back to the gas-liquid separation element 6 through the third interface 63 for recirculation. It should be pointed out that: the plate heat exchanger 203 mainly exchanges heat between the working fluid and the electronic components such as the battery pack in the vehicle thermal management system; the indoor heat exchanger 202 mainly exchanges heat between the working fluid and the indoor air of the vehicle; and the outdoor heat exchanger 201 mainly exchanges heat between the working fluid and the outdoor ambient air of the vehicle.

[0025] Referring to Figure 3 and Figure 5 , the second working mode: the second switch valve element 22 is closed, the first switch valve element 21, the third switch valve element 23, and the first throttling valve element 31 are opened, at this time, the first channel 51 is in communication with the second channel 52 through the first switch valve element 21, the third channel 53 is in communication with the fourth channel 54 through the third switch valve element 23, and the seventh channel 57 is in communication with the sixth channel 56 through the first throttling valve element 31.

[0026] At this time, the high-temperature and high-pressure working fluid (gas phase) at the outlet side of the compressor 200 flows from the first port 510 into the first channel 51, flows into the second channel 52 through the first switch valve element 21, and flows from the second port 520 to the indoor heat exchanger 202 (at this time, the fourth switch valve element 24 is closed), becomes a relatively high-temperature and high-pressure working fluid (gas-liquid two-phase) after heat exchange and heat dissipation through the indoor heat exchanger 202, flows into the sixth channel 56 through the seventh port 560, and a part of the working fluid in the sixth channel 56 becomes a low-temperature and low-pressure working fluid after throttling through the first throttling valve element 31, enters the seventh channel 57, and enters the gas-liquid separation element 6 through the fourth interface 64. After gas-liquid two-phase separation through the gas-liquid separation element 6, the gas-phase working fluid flows back to the compressor 200 through the first interface 61, and the liquid-phase working fluid flows to the outdoor heat exchanger 201 through the second interface 62, becomes a relatively low-temperature and low-pressure working fluid after heat exchange and heat absorption through the outdoor heat exchanger 201, enters the third channel 53 through the third port 530, and flows to the fourth channel 54 through the third switch valve element 23. The fourth channel 54 is directly communicated with the fifth channel 55, and the fluid in the fourth channel 54 flows to the fifth channel 55 and enters the gas-liquid separation element 6 through the third interface 63 for recirculation. Another part of the working fluid in the sixth channel 56 flows to the plate heat exchanger 203 through the eighth port 561, flows into the fifth channel 55 through the fifth port 550 after heat exchange and heat dissipation through the plate heat exchanger 203, and also flows back to the gas-liquid separation element 6 through the third interface 63 for recirculation.

[0027] Referring to Figures 1 to 5 In the first working mode, the working fluid in the first channel 51 and the third channel 53 is the high-temperature working fluid at the outlet side of the compressor 200, and the working fluid in the fourth channel 54, the fifth channel 55, and the sixth channel 56 is a low-temperature working fluid or a relatively low-temperature working fluid. In the second working mode, the working fluid in the first channel 51 and the second channel 52 is a high-temperature working fluid, and the working fluid in the third channel 53, the fourth channel 54, the fifth channel 55, and the seventh channel 57 is a low-temperature or a relatively low-temperature fluid.

[0028] In this way, in different working modes, the temperatures of the working fluids in different channels are different. In order to reduce the mutual interference of the temperatures of the working fluids in different channels caused by the heat conduction of the valve block 1, which is beneficial to the stable operation of the system, referring to Figure 2 、 Figure 3 and Figure 6The valve block 1 specifically comprises a first part 11, a second part 12 and a third part 13. A part of the flow channel is located in the first part 11, another part of the flow channel is located in the second part 12, and still another part of the flow channel is located in the third part 13. The first part 11 is connected with the second part 12, and the second part 12 is connected with the third part 13. The second part 12 is located between the first part 11 and the third part 13. In the embodiment, the first part (including the first sub-channel 511) of the first channel 51, the second channel 52 and the first mounting cavity 41 are located in the first part 11. The second part of the first channel 51, the third channel 53, the first part of the fourth channel 54, the second mounting cavity 42 and the fourth mounting cavity 43 are located in the second part 12. The valve block 1 comprises a first groove 14 and a first connecting part 15. In the axial direction of the mounting cavity, the first groove 14 is recessed from the outer wall of the valve block 1 inwardly to form a first groove cavity 140. The first groove cavity 140 is located between the first part 11 and the second part 12. At least part of the wall surface of the first groove 14 forms the wall surface of the first connecting part 15. The first connecting part 15 connects the first part 11 and the second part 12. The first connecting part 15 has a first channel segment. The first channel segment communicates the part of the flow channel located in the first part 11 and the part of the flow channel located in the second part 12. In the embodiment, the third part (i.e. the first channel segment) of the first channel 51 is located in the first connecting part 15. The third part of the first channel 51 communicates the first part of the first channel 51 located in the first part 11 and the second part of the first channel 51 located in the second part 12. The first groove cavity 140 is provided, which is beneficial to reduce the mutual interference of the channels located in the first part 11 and the channels located in the second part 12, reduce the harmful heat transfer between the working fluids at different temperatures in different channels, and facilitate the stable operation of the thermal management system. Specifically, in the second working mode, the working fluid in the first sub-channel 511 and the second channel 52 located in the first part 11 is high-temperature working fluid, and the working fluid in the third channel 53 located in the second part is relatively low-temperature working fluid. Due to the temperature difference, heat exchange occurs between the working fluid located in the first part 11 and the working fluid located in the second part 12. Such heat exchange reduces the performance of the thermal management system and is not conducive to the stable operation of the thermal management system.

[0029] The valve block 1 further comprises a second groove 16 and a second connecting portion 17. The second groove 16 is formed by recessing inwardly from the outer wall of the valve block 1 along the axial direction of the mounting cavity, and the second groove 16 forms a second groove cavity 160. The second groove cavity 160 is located between the second portion 12 and the third portion 13. At least part of the wall of the second groove 16 forms the wall of the second connecting portion 17. The second connecting portion 17 connects the second portion 12 and the third portion 13. The second connecting portion 17 has a second passage section. The second passage section communicates the part of the flow channel located in the second portion 12 and the part of the flow channel located in the third portion 13. In the embodiment, the second part of the fourth passage 54, the fifth passage 55, the sixth passage 56, the seventh passage 57, and the third mounting cavity 43 are located in the third portion 13. The third part (i.e., the second passage section) of the fourth passage 54 is located in the second connecting portion 17. The third part of the fourth passage 54 communicates the first part of the fourth passage 54 located in the second portion 12 and the second part of the fourth passage 54 located in the third portion 13. The second groove cavity 160 is arranged to facilitate reducing the mutual interference between the temperature of the working fluid (high-temperature working fluid in the first working mode) in the working passage such as the third passage 53 located in the second portion 12 and the temperature of the working passage (low-temperature or relatively low-temperature working fluid in the first working mode) in the working passage such as the fifth passage 55 and the sixth passage 56 located in the third portion 13, to facilitate reducing the harmful heat transfer between the different temperatures of the working fluid in different passages, and to facilitate stable operation of the thermal management system.
