[0025] Please refer to Figures 1 to 3 , Figure 1 is a structural schematic diagram of an embodiment of a compressor assembly provided by the present application, Figure 2 yes Figure 1 Schematic diagram of the cross-sectional structure of the compressor assembly after assembly. Figure 3 yes Figure 1Structural schematic diagram of the housing. In one aspect of the present application, a compressor assembly 100 is provided, which includes a housing 1 and a controller 2. The housing 1 is provided with a receiving chamber 11, a cooling channel 12 and a supporting partition 13. The supporting partition 13 separates the receiving chamber 11 from the cooling channel 12. The supporting partition 13 is provided with an inlet channel 131 and an outlet channel 132 connecting the cooling channel 12 and the receiving chamber 11. The controller 2 includes a power module 21, a circuit board 22 and a cooling plate 23 installed in the receiving chamber 11. The cooling plate 23 is located between the power module 21 and the circuit board 22, and the cooling plate 23 presses the power module 21 against the supporting partition 13. Specifically, a refrigerant inlet 231, a refrigerant outlet 232 and a refrigerant flow channel 233 are provided on the cooling plate 23. The refrigerant flow channel 233 connects the refrigerant inlet 231 and the refrigerant outlet 232. The refrigerant inlet 231 is connected to the inlet channel 131, and the refrigerant outlet 232 is connected to the outlet channel 132, so that the refrigerant flow channel 233 can be connected to the cooling channel 12 of the shell 1.

[0026] Specifically, the supporting partition 13 can play the role of separating the receiving cavity 11 and the cooling channel 12 and supporting the controller 2. When in use, the controller 2 of the present application will inevitably generate heat. The controller 2 can be thermally interacted with by the refrigerant circulating in the refrigerant channel and the cooling channel 12, and the heat generated by the controller 2 can be taken away, thereby cooling the controller 2. Specifically, since the refrigerant flow channel 233 is connected with the cooling channel 12, after the refrigerant enters the cooling channel 12, a part of the refrigerant can flow into the refrigerant channel through the inlet channel 131 and the refrigerant inlet 231, so as to thermally interact with the circuit board 22 and the side of the power module 21 facing the circuit board 22, and then flow back to the cooling channel 12 through the outlet channel 132 and the refrigerant outlet 232, thereby taking away part of the heat of the circuit board 22 and the power module 21; the other part directly circulates in the cooling channel 12, and thermally interacts with the side of the power module 21 facing away from the circuit board 22, taking away the heat of the power module 21, thereby achieving heat dissipation and cooling. Through the above cooling method, the power module 21 has two cooling methods, which improves the cooling effect. The circuit board 22 and the power module 21 can both obtain good cooling conditions, which shortens the high-temperature operation time of the controller 2 and improves reliability. The cooling plate 23 can not only cool down the temperature, but also press and fix, which reduces the number of parts in the receiving cavity 11, simplifies the structure, and thus reduces the cost.

[0027] In one embodiment of the present application, Figure 4 As shown, Figure 4 yes Figure 1Schematic diagram of the assembly structure of the medium power module and the cooling plate. The cooling plate 23 includes a support plate body 234 and two connecting parts 235 connecting the support plate body 234. The refrigerant inlet 231 and the refrigerant outlet 232 respectively penetrate the end surface of the connecting part 235 facing away from the support plate body 234; the support plate body 234 is fixedly connected to the support partition 13, and the connecting part 235 is respectively fixedly connected to the inlet channel 131 and the outlet channel 132; the circuit board 22 is arranged on the support plate body 234 so as to be cooled by the support plate body 234.

[0028] Specifically, the refrigerant flow channel 233 is arranged in the support plate body 234 and extends along the support plate body 234 to connect the refrigerant inlet 231 and the refrigerant outlet 232. The refrigerant in the support plate body 234 can directly take away the heat generated by the circuit board 22, thereby achieving heat dissipation and cooling of the circuit board 22. The cooling plate 23 also includes a fixed end face 236, which is connected to the connecting portion 235 and is used to fix the connecting portion 235 on the support partition 13. In a specific embodiment, combined with Figure 3 and Figure 4 The fixed end surface 236 may be an end surface extending from the support plate body 234 to the connection portion 235. The fixed end surface 236 is provided with fixing holes 2361 located on opposite sides of the connection portion 235. The support partition 13 is also provided with corresponding mounting holes 134, so that bolts can be passed through the fixing holes 2361 and the mounting holes 134 in sequence, so that the connection portion 235 is installed and fixed on the support partition 13. Furthermore, the mounting holes 134 are also correspondingly located on both sides of the inlet channel 131 or the outlet channel 132, so that the connection portion 235 is fixedly connected to the inlet channel 131 and the outlet channel 132 respectively, so that the refrigerant flow channel 233 is connected to the cooling channel 12.

[0029] In one embodiment of the present application, the controller 2 further includes a sealing ring 3 , which is sleeved on the connecting portion 235 ; the sealing ring 3 abuts against the connecting portion 235 and the inner walls of the corresponding inlet channel 131 and outlet channel 132 .

[0030] Specifically, the connection part 235 can extend into the inlet channel 131 and the outlet channel 132 respectively, so as to realize the communication between the refrigerant flow channel 233 and the cooling channel 12. In order to improve or avoid the refrigerant from penetrating or leaking out between the outer periphery of the connection part 235 and the inner wall of the inlet channel 131 or the outlet channel 132, a sealing ring 3 is sleeved on the outer periphery of the connection part 235 to seal the outer periphery of the connection part 235 with the inlet channel 131 and the outlet channel 132 respectively, to avoid the leakage of the refrigerant and improve the reliability. The sealing ring 3 is sleeved on the outer periphery of the connection part 235 and can also reduce the influence of the displacement of the cooling plate 23 during the compression process on the sealing effect. One sealing ring 3 can be used to simplify the structure and reduce the cost. Of course, multiple sealing rings 3 can also be used to improve the sealing effect and reduce the risk of failure.

[0031] In one embodiment of the present application, the controller 2 further includes a first heat conducting member 4 , which is located between the support plate 234 and the circuit board 22 to improve the heat conduction efficiency between the support plate 234 and the circuit board 22 .

[0032] Furthermore, the controller 2 further includes a second heat conducting member 5 , which is located between the bottom surface of the cooling plate 23 facing away from the circuit board 22 and the power module 21 , so as to improve the heat conduction efficiency between the cooling plate 23 and the power module 21 .

[0033] Furthermore, the controller 2 further includes a third heat conducting member 6 , which is located between the power module 21 and the supporting baffle 13 to improve the heat conduction efficiency between the power module 21 and the supporting baffle 13 .

[0034] The first heat conducting member 4, the second heat conducting member 5 and the third heat conducting member 6 can all be elastic insulating heat conducting pads, which have a certain pressure deformation and insulation performance, and can play the role of insulation, heat conduction and buffering vibration reduction, protect the circuit board 22, the cooling plate 23 and the power module 21, and improve reliability. Furthermore, in the process of the cooling plate 23 pressing the power module 21, the elastic insulating heat conducting pad can also provide the pressing force of the power module 21, improve or avoid the stress concentration phenomenon.

[0035] Combination Figure 3 The support baffle 13 also includes a heat dissipation surface 135, which is located on the side of the support baffle 13 facing away from the cooling channel 12, and is used to contact and cool the controller 2. In the embodiment of the present application, the third heat-conducting member 6 can be laid flat on the heat-dissipating surface 135 to increase the contact area with the power module 21, improve the heat conduction efficiency and heat dissipation effect. Furthermore, the first heat-conducting member 4, the second heat-conducting member 5 and the third heat-conducting member 6 can all be laid flat and without wrinkles, thereby improving the uniformity of heat conduction, improving or avoiding the phenomenon of heat concentration, and improving reliability.

[0036] In one specific embodiment, the controller 2 may include only the first heat conducting member 4 or the third heat conducting member 6 to reduce the cost. In another specific embodiment, the controller 2 may also include the first heat conducting member 4 and the second heat conducting member 5 to improve the heat conduction efficiency. In another specific embodiment, the controller 2 may also include the first heat conducting member 4 and the third heat conducting member 6. In another specific embodiment, the controller 2 may also include the second heat conducting member 5 and the third heat conducting member 6. Of course, if Figure 4 As shown, in other specific embodiments, the controller 2 may also include a first heat conducting member 4, a second heat conducting member 5 and a third heat conducting member 6. The configuration may be based on the actual heat dissipation requirements of the controller 2, and will not be described in detail here.

[0037] Furthermore, if Figure 1 and Figure 2 As shown, the controller 2 further includes an electrical connector 24 , which is mounted on the housing 1 and connected to the circuit board 22 , and is used to support and fix the circuit board 22 and improve the stability of current transmission.

[0038] Furthermore, the installation process of the controller 2 of the embodiment of the present application is as follows: the third heat-conducting member 6 is first laid flat on the heat dissipation surface 135 of the supporting partition 13, and after ensuring that it is laid flat and wrinkle-free, the power module 21 is installed on the third heat-conducting member 6, and after the installation is completed, the second heat-conducting member 5 is placed on the power module 21, and the electrical connector 24 is fixed to the housing 1, and then the cooling plate 23 is fastened to the supporting partition 13 by a number of bolts, and the power module 21, the third heat-conducting member 6 and the second heat-conducting member 5 are pressed by the cooling plate 23; finally, the first heat-conducting member 4 is placed on the cooling plate 23, and then the circuit board 22 is installed. It should be noted that the copper clad layer 221 of the circuit board 22 is in direct contact with the first heat-conducting member 4, so as to conduct the heat generated by the current on the copper clad layer 221 to the first heat-conducting member 4, and the welding hole 222 of the circuit board 22 is correspondingly welded with the welding piece 241 of the electrical connector 24, so as to facilitate stable current transmission. Through the above structure, the temperature of the power module 21 and the circuit board 22 can be reduced, the current capacity of the controller 2 can be improved, the available space can be expanded, and the reliability can be improved.

[0039] In one embodiment of the present application, the support partition 13 is provided with a guide portion 133 protruding toward the cooling channel 12; the shell 1 is also provided with a refrigerant inlet 7 connected to the cooling channel 12; the guide portion 133 at least partially surrounds the inlet channel 131, and the guide portion 133 is provided with an inclined guide surface 1331 extending toward the refrigerant inlet 7 in the direction of the refrigerant inlet 7.

[0040] Specifically, the guide portion 133 is used to guide the refrigerant flow into the inlet channel 131. The refrigerant inlet 7 is located at one end of the cooling channel 12, and the inlet channel 131 and the outlet channel 132 are located at the other end of the cooling channel 12 away from the refrigerant inlet 7. Therefore, after the refrigerant enters the cooling channel 12 through the refrigerant inlet 7, it can flow to the other end along the cooling channel 12, and under the action of the guide portion 133, part of the refrigerant is guided to the inlet channel 131, thereby realizing two cooling methods of the refrigerant flow channel 233 and the cooling channel 12 to cool the power module 21 and improve the cooling effect. It should be noted that the housing 1 is also provided with an outlet connected to the cooling channel 12 for discharging the refrigerant. The outlet is located at the other end of the compressor assembly 100. After the refrigerant flows out of the cooling channel 12, it will also pass through the installation cavity 8 to cool the motor, compressor, etc. in the installation cavity 8, and finally be discharged from the outlet.

[0041] When in use, refrigerant can be continuously introduced into the cooling channel 12 to keep the refrigerant flowing, which can improve the cooling effect. The guide portion 133 can ensure that part of the refrigerant can always enter the refrigerant flow channel 233 of the cooling plate 23 through the inclined guide surface 1331, while ensuring the fluidity of the refrigerant in the refrigerant flow channel 233, so that the cooling plate 23 is in a heat dissipation state, which can increase the heat taken away from the circuit board 22 and the power module 21 and improve the heat dissipation efficiency. Since the guide portion 133 is arranged around the inlet channel 131, only part of the refrigerant in the cooling channel 12 can be guided to flow to the inlet channel 131, so as to reduce the impact on the flow in the cooling channel 12, thereby reducing the impact on the performance of the compressor.

[0042] In one embodiment of the present application, Figure 2 As shown, the housing 1 is further provided with a mounting cavity 8 , which is located on a side of the cooling channel 12 facing away from the supporting partition 13 . The compressor assembly 100 also includes a compressor, which is disposed in the mounting cavity 8 .

[0043] Specifically, the refrigerant after dissipating heat and cooling the circuit board 22 and the power module 21 can continue to flow along the shell 1 to the installation cavity 8 through the cooling channel 12 to cool the compressor located in the installation cavity 8, thereby improving the heat dissipation efficiency and enhancing the performance of the compressor.
