[0023] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] It should be clearly stated that the described technical solutions are only a part of the technical solutions in this application, not all of them. Based on the technical solutions in this application, all other technical solutions obtained by a person skilled in the art without inventive effort are within the scope of protection of this application.

[0025] The thermal management integrated assembly 100 includes a thermal management component 101 and a flow channel assembly 1. The thermal management component 101 is mounted on the flow channel assembly 1, which has multiple flow channels for connecting the thermal management integrated assembly 100. Related technologies have a need to further improve the integration level of the thermal management integrated assembly 100.

[0026] The existing thermal management integrated assembly 100 already integrates various types of thermal management components 101, including valves, sensors, and heat exchangers. Further improving the integration level of the thermal management integrated assembly 100 is challenging. The inventors discovered that the thermal management system corresponding to the thermal management integrated assembly 100 includes a compressor, and to reduce compressor lubricant loss, the thermal management system requires compressor oil return. Integrating the compressor oil return components into the existing thermal management integrated assembly 100 could further improve the integration level of the heat pipe integrated assembly.

[0027] Therefore, this application provides a thermal management integrated component 100, for example... Figures 1-14 As shown, the device includes a thermal management component 101 and a flow channel assembly 1. The thermal management component 101 is mounted on the flow channel assembly 1 and includes at least one of a valve, a sensor, and a heat exchanger. The thermal management assembly 100 includes an oil separator 2 having a first oil outlet 22 and a second oil outlet 24. The flow channel assembly 1 has at least two flow channels, including a main flow channel 11 and a return flow channel 12. The first oil outlet 22 communicates with the return flow channel 12, and the second oil outlet 24 communicates with the main flow channel 11.

[0028] The thermal management integrated component 100 provided in this application includes an oil separator 2 and a flow channel assembly 1. The first oil outlet 22 of the oil separator 2 is connected to the return oil flow channel 12 of the flow channel assembly 1, and the second oil outlet 24 of the oil separator 2 is connected to the main flow channel 11 of the flow channel assembly 1. Thus, compared with the thermal management integrated component 100 of the related technology, it can increase the oil separation function, which is conducive to further improving the integration of the thermal management integrated component 100.

[0029] It is understood that the thermal management integrated component 100 in this application includes an oil separator 2. Therefore, during the operation of the thermal management system corresponding to the thermal management integrated component 100, the oil separator 2 can separate the refrigerant from the compressor lubricating oil. The separated lubricating oil enters the return oil channel 12 from the first oil separator outlet 22 and then flows back into the compressor. The separated refrigerant enters the main channel 11 from the second oil separator outlet 24, thereby realizing thermal management.

[0030] For the thermal management system corresponding to the thermal management integrated component 100, the return oil flow path can be considered as a bypass flow path of the main flow path. During system operation, the flow rate of the bypass flow path needs to be controlled to reduce the impact of the bypass flow path on the refrigerant flow rate in the main flow path. Therefore, in some embodiments, the thermal management integrated component 100 includes a first capillary tube 3, and the flow channel integrated component 1 and the oil separator 2 are all connected to the first capillary tube 3. The first capillary tube 3 has a first capillary conduit 31, a first port 321, and a second port 331. The first port 321 is the inlet of the first capillary tube 3, and the second port 331 is the outlet of the first capillary tube 3. The first port 321 connects the first capillary conduit 31 and the first oil separator outlet 22, and the second port 331 connects the return oil flow path 12 and the first capillary conduit 31. That is, the first capillary conduit 31 connects the first oil separator outlet 22 and the return oil flow path 12. The first capillary tube 3 plays a throttling role, controlling the flow rate of the bypass flow path mentioned above.

[0031] It is understood that the oil separator 2, the first capillary tube 3, and the oil return channel 12 provided in the flow channel assembly 1 are combined to realize the oil return function of the thermal management integrated assembly 100.

[0032] In some implementations, for example Figure 3 , Figures 10-12As shown, the at least two flow channels mentioned above include a first connecting channel 131. The flow channel assembly 1 includes a first flow channel portion 13, and the first connecting channel 131 is disposed in the first flow channel portion 13. The oil separator 2 includes a first oil distribution pipe 21, which has a first oil outlet 22. The first oil distribution pipe 21 and the first capillary tube 3 are both connected to the first flow channel portion 13. The first connecting channel 131 connects the first capillary tube 31 and the first oil outlet 22. The flow channel assembly 1 includes a first filter portion 132, which is located in the first connecting channel 131. The first oil distribution pipe 21 and the first capillary tube 3 are respectively located on both sides of the first filter portion 132. The first filter portion 132 has filter holes. The first connecting channel 131 includes a first sub-channel 133 and a second sub-channel 134. At least a portion of the first sub-channel 133 and at least a portion of the second sub-channel 134 are respectively located on both sides of the first filter portion 132. Both the first sub-channel 133 and the second sub-channel 134 are connected to the filter holes. Alternatively, the first filter section 132 divides the first connecting channel 131 into a first sub-channel 133 and a second sub-channel 134. For example... Figure 3 As shown, along the extension direction of the filter holes, the first sub-channel 133 and the second sub-channel 134 are located on both sides of the filter holes, respectively. The first sub-channel 133 is directly connected to the first oil separator outlet 22, and the second sub-channel 134 is directly connected to the first capillary tube 31. In this way, the refrigerant carrying lubricating oil flowing out of the first oil separator outlet 22 can be filtered by the first filter section 132 before entering the first capillary tube 31, thereby reducing the risk of blockage of the first capillary tube 31.

[0033] For example Figure 3As shown, the first connecting channel 131 includes a first main connecting channel 135 and a first branch connecting channel 136, with the first main connecting channel 135 communicating with the first branch connecting channel 136. The first main connecting channel 135 includes a first sub-channel 133 and a portion of a second sub-channel 134. A first filter section 132 is located in the first main connecting channel 135, and the second sub-channel 134 includes the first branch connecting channel 136. The flow channel assembly 1 has a first direction D1 and a second direction D2, with the first direction D1 perpendicular to the second direction D2. The first main connecting channel 135 extends along the first direction D1, with one side of the first main connecting channel 135 closed and the other side having an opening. A first oil distributor 21 partially penetrates the opening of the first main connecting channel 135, and a portion of the first oil distributor 21 is located within the first main connecting channel 135. Specifically, a portion of the first oil distributor 21 is located within the first sub-channel 133, and the outer wall of the first oil distributor 21 is fixedly connected to the inner wall of the first sub-channel 133. Along the first direction D1, the first oil separator outlet 22 is farther away from the second sub-channel 134 relative to the first filter section 132, and the first branch connecting channel 136 is farther away from the first sub-channel 133 relative to the first filter section 132. The first branch connecting channel 136 penetrates the wall of the first main connecting channel 135 along the second direction D2. One end of the first capillary 3 is located in the first branch connecting channel 136, and the outer wall of the first capillary 3 is fixedly connected to the inner wall of the first branch connecting channel 136. The flow area of ​​the first main connecting channel 135 is larger than the flow area of ​​the first branch connecting channel 136.

[0034] In some embodiments, the at least two flow channels mentioned above include a second connecting channel 141. The flow channel assembly 1 includes a second flow channel portion 14, where both the second connecting channel 141 and the return oil flow channel 12 are disposed. The first capillary tube 3 is connected to the second flow channel portion 14, and the second connecting channel 141 connects the first capillary tube 31 and the return oil flow channel 12. In some embodiments, the first flow channel portion 13 and the second flow channel portion 14 are integrally formed. In some embodiments, the flow channel assembly 1 is integrally formed. The flow channel assembly 1 is a block-shaped component, and may also be referred to as a flow channel assembly block.

[0035] Specifically, the first capillary tube 3 includes a first end 32 and a second end 33. The first end 32 has a first port 321, and the second end 33 has a second port 331. The first end 32 is connected to the first flow channel 13, and both the first capillary tube 31 and the first connecting channel 131 are connected to the first port 321. Specifically, both the first capillary tube 31 and the second sub-channel 134 are connected to the first port 321. The second end 33 is connected to the second flow channel 14, and both the first capillary tube 31 and the second connecting channel 141 are connected to the second port 331. Thus, both the first connecting channel 131 and the second connecting channel 141 are normally open to the first capillary tube 31. Since the first connecting channel 131 connects the first oil separator outlet 22 and the first capillary tube 31, and the second connecting channel 141 connects the return oil flow channel 12 and the first capillary tube 31, the return oil flow channel and the first oil separator outlet 22 are also normally open to the first capillary tube 31. The refrigerant carrying lubricating oil from the first oil separator outlet 22 enters the first connecting channel 131. The refrigerant flowing out of the first connecting channel 131 enters the first capillary tube 31 through the first port 321. After being throttled by the first capillary tube 31, it flows into the second connecting channel 141 through the second port 331. Then, it enters the return oil channel 12 from the second connecting channel 141 and can then flow back to the compressor through the return oil channel 12.

[0036] In some embodiments, the thermal management integrated assembly 100 includes a second capillary 4, with the flow channel assembly 1 and oil separator 2 both connected to the second capillary 4. The second capillary 4 has a second capillary channel 41, and a first capillary 3 is arranged in parallel with the second capillary 4. The thermal management integrated assembly 100 has a first state and a second state. In the first state, both the first oil separator outlet 22 and the return oil flow channel 12 are connected to the second capillary channel 41; in the second state, at least one of the first oil separator outlet 22 and the return oil flow channel 12 is fluidly isolated from the second capillary channel 41.

[0037] Specifically, the second capillary 4 includes a third end 42 and a fourth end 43. The third end 42 is connected to the first flow channel portion 13, and the fourth end 43 is connected to the second flow channel portion 14. The first connecting channel 131 connects the second capillary 41 and the first oil separator outlet 22. Specifically, for example, combined with... Figure 4 and Figure 5 As shown, the third end 42 has a third port 421, through which both the second capillary 41 and the first connecting channel 131 are connected. Specifically, both the second capillary 41 and the second sub-channel 134 are connected to the third port 421. The fourth end 43 has a fourth port 431. In the first state, both the second capillary 41 and the return oil channel 12 are connected to the fourth port 431. In the second state, the second capillary 41 is connected to the fourth port 431, while the return oil channel 12 is fluidly isolated from the fourth port 431.

[0038] In some embodiments, the thermal management component 101 includes a control valve 20 mounted on the flow channel assembly 1. Specifically, the control valve 20 is mounted on the second flow channel portion 14. Specifically, the flow channel assembly 1 (second flow channel portion 14) has a first mounting cavity 140, and the control valve 20 is at least partially located in the first mounting cavity 140. The second flow channel portion 14 has a second communication channel 141, through which the first capillary duct 31 and the return flow channel 12 are both connected. The second capillary duct 41 is connected to the first mounting cavity 140. In a first state, the control valve 20 is open, and the first mounting cavity 140 is connected to the second communication channel 141; in a second state, the control valve 20 is closed, and the first mounting cavity 140 is fluidly isolated from the second communication channel 141. Thus, by setting a simple flow channel structure in the second flow channel section 14, it is possible to achieve constant flow between the first capillary channel 31 and the return oil flow channel 12, while the second capillary channel 41 and the return oil flow channel 12 can be selectively switched on and off, which helps to reduce the processing cost of the thermal management integrated component 100.

[0039] In some embodiments, the flow channel assembly 1 has a first direction D1 and a second direction D2, the first direction D1 being perpendicular to the second direction D2; the second connecting channel 141 extends along the first direction D1, and the first mounting cavity 140 and the oil return flow channel 12 both extend along the second direction D2. In some embodiments, for example... Figure 5 As shown, the second connecting channel 141 extends through the first mounting cavity 140 along the first direction D1. The flow channel assembly 1 has a third connecting channel 201, which connects the second capillary tube 41 and the first mounting cavity 200.

[0040] In some embodiments, along the first direction D1, the second end 33 of the first capillary 3 and the fourth end 43 of the second capillary 4 are located on the same side of the second flow channel 14, and the second end 33 of the first capillary 3 and the return oil flow channel 12 are located on both sides of the second connecting channel 141, respectively.

[0041] In some embodiments, the thermal management integrated assembly 100 includes a first connection portion 102, which has a main channel 1022, a first branch channel 1024, and a second branch channel 1026, both of which are connected to the main channel 1022. The first connection portion 102 includes a first sub-connection portion 1021, a second sub-connection portion 1023, and a third sub-connection portion 1025. The main channel 1022 is at least partially disposed in the first sub-connection portion 1021, the first branch channel 1024 is at least partially disposed in the second sub-connection portion 1023, and the second branch channel 1026 is at least partially disposed in the third sub-connection portion 1025. The first sub-connecting part 1021 is connected to the first flow channel part 13, and the main channel 1022 is connected to the first connecting channel 131; the second sub-connecting part 1023 is connected to the first capillary tube 3, the first branch channel 1024 connects the first capillary tube 31 and the main channel 1022, the third sub-connecting part 1025 is connected to the second capillary tube 4, and the second branch channel 1026 connects the second capillary tube 41 and the main channel 1022. That is, both the first capillary tube 3 and the second capillary tube 4 mentioned above are connected to the first flow channel part 13 through the first connecting part 102. Thus, by opening a connection port in the first flow channel part 13 for inserting the first connecting part 102, the first connecting channel 131 can be simultaneously connected to the first capillary tube 31 and the second capillary tube 41. The first branch connecting channel 136 mentioned above includes this connection port for inserting the first connecting part 102. Correspondingly, providing a first connecting channel 136 in the first flow channel 13 enables communication between the first connecting channel 131 and the first capillary channel 31 and the second capillary channel 41. In some embodiments, for example... Figure 13 and Figure 14 As shown, the first connecting part 102 is Y-shaped.

[0042] In some embodiments, the thermal management integrated assembly 100 includes a second connecting portion 103 and a third connecting portion 104. A first capillary 3 is connected to a second flow channel portion 14 via the second connecting portion 103, and a second capillary 4 is connected to the second flow channel portion 14 via the third connecting portion 104, for example... Figure 5 As shown. This facilitates the connection between the first capillary tube 31 and the second connecting channel 141, while the second capillary tube 41 is connected to the first mounting cavity 140, thereby achieving the normal flow between the first capillary tube 31 and the return oil channel 12, and the selective connection between the second capillary tube 41 and the return oil channel 12.

[0043] In some embodiments, the thermal management component 101 includes a multi-way valve 5 having multiple ports, one of which communicates with the main flow channel 11. Specifically, for example... Figure 1 , Figure 6 and Figure 7As shown, multiple valve ports include a first valve port 510, a second valve port 520, a third valve port 530, and a fourth valve port 540. The flow channel assembly 1 includes a third flow channel section 15, to which both the first flow channel section 13 and the second flow channel section 14 are connected, and a main flow channel 11 is disposed in the third flow channel section 15. The oil separator 2 includes a second oil distribution pipe 23, which has a second oil distribution outlet 24. The second oil distribution pipe 23 is connected to the third flow channel section 15 and communicates with the main flow channel 11. The multi-way valve 5 includes a first valve port section 51, to which a first valve port 510 is disposed. The first valve port section 51 is connected to the third flow channel section 15 and communicates with the main flow channel 11. Alternatively, the main flow channel 11 connects the second oil distribution outlet 24 and the first valve port 510. The oil separator 2 has an oil distribution inlet 25, which can communicate with the compressor outlet.

[0044] In some embodiments, the thermal management integrated assembly 100 has a third direction D3, and the first direction D1 and the second direction D2 mentioned above are both perpendicular to the third direction D3. Along the third direction D3, the multi-way valve 5 is located on one side of the flow channel integrated assembly 1. Specifically, for example... Figure 4 As shown, along the third direction D3, the third flow channel 15 and the multi-way valve 5 are located on both sides of the first flow channel 13, and the second flow channel 14 is located away from the first flow channel 13 relative to the third flow channel 15. This facilitates a compact arrangement of the components included in the thermal management integrated assembly 100 and helps to reduce the size of the thermal management integrated assembly 100.

[0045] In some embodiments, the multi-way valve 5 includes a second valve port 52, and a second valve port 520 is disposed in the second valve port 52; the flow channel assembly 1 includes a first pipe connection 17, which is connected to the second valve port 52 and has a first communicating flow channel 170, which communicates with the second valve port 520. In some embodiments, the thermal management integrated assembly 100 includes a first pipe 63, which is capable of flowing gaseous refrigerant. The first pipe connection 17 is fixedly connected to the first pipe 63, and the first communicating flow channel 170 communicates with the inner cavity of the first pipe 63. A third valve port 530 is capable of communicating with an outdoor heat exchanger, and a fourth valve port 540 is capable of communicating with a gas-liquid separator. In some embodiments, along the second direction D2, the first pipe connection 17 is located on one side of the first flow channel 13. For example, along the direction of gravity, the first pipe connection 17 is located below the first flow channel 13. In some embodiments, the first pipe 63 is connected to a second shut-off valve 113.

[0046] In some embodiments, the thermal management integrated assembly 100 includes a first throttle valve 61 mounted on the flow channel assembly 1; at least two flow channels include throttling channels 161, and the first throttle valve 61 is capable of throttling the fluid within the throttling channels 161. The flow channel assembly 1 has a third direction D3, and a first direction D1 and a second direction D2 are both perpendicular to the third direction D3. Along the third direction D3, the first throttle valve 61 and the multi-way valve 5 are located on both sides of the main flow channel 11.

[0047] In some embodiments, the thermal management component 101 includes a first throttling valve 61, and the flow channel assembly 1 includes a fourth flow channel portion 16, with the first throttling valve 61 mounted on the fourth flow channel portion 16. At least two flow channels include a throttling channel 161, which is disposed in the fourth flow channel portion 16, and the first throttling valve 61 is capable of throttling the fluid within the throttling channel 161. In some embodiments, the thermal management assembly 100 includes a second filter portion 62, which is located in the throttling channel 161; the fourth flow channel portion 16 includes an inlet portion 162 and an outlet portion 164, and the throttling channel 161 has a throttling inlet 163 and a throttling outlet 165, with the throttling inlet 163 disposed in the inlet portion 162 and the throttling outlet 165 disposed in the outlet portion 164, and the inlet portion 162 and the first throttling valve 61 respectively located on both sides of the second filter portion 62. Thus, the fluid can enter the second filter section 62 before entering the first throttle valve 61, thereby reducing clogging of the first throttle valve 61. In some embodiments, the throttle inlet 163 can communicate with the outdoor heat exchanger. In some embodiments, along the third direction D3 described above, the fourth flow channel section 16 is located away from the first flow channel section 13 relative to the second flow channel section 14. Similarly, this facilitates a compact arrangement of the components included in the thermal management integrated assembly 100, which helps to reduce the size of the thermal management integrated assembly 100.

[0048] In some embodiments, the thermal management component 101 includes a plate heat exchanger 7, a second throttling valve 8, a connecting block 9, and a third capillary tube 10, for example... Figure 1 , Figure 2 , Figure 6 and Figure 7As shown. A plate heat exchanger 7 is mounted on a flow channel assembly 1. The plate heat exchanger 7 has a first heat exchange flow channel 71 and a second heat exchange flow channel 72. In the plate heat exchanger 7, the fluid flowing through the first heat exchange flow channel 71 exchanges heat with the fluid flowing through the second heat exchange flow channel 72. The plate heat exchanger 7 includes a plurality of plates 70, which are stacked. The plate heat exchanger 7 has an inter-plate flow channel 701 and a distribution flow channel 700. Along the stacking direction of the plates 70, the inter-plate flow channel 701 is located between two adjacent plates 70. In some embodiments, the stacking direction of the plates 70 is the same as that of a first direction D1. The inter-plate flow channel 701 includes at least two first inter-plate flow channels 702 and at least two second inter-plate flow channels 703.
