[0002] This application is based on and claims priority to Chinese Patent Application No. 202510112821.2, filed on January 22, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of compressor technology, and in particular to a compressor, a thermal management system, and a vehicle. Background Technology

[0004] In existing technology, the compressor motor is located in the low-pressure chamber of the refrigerant system, and the motor and electronic control are cooled by low-pressure refrigerant. On the one hand, the refrigerant flow rate changes continuously with vehicle conditions and ambient temperature, with a wide range of variation. At low refrigerant flow rates, there is a risk of overheating in the motor and electronic control system. On the other hand, the temperature of low-pressure refrigerant is usually around 0°C. Refrigerant at this temperature carries high-grade cold energy, while the temperature of the motor and electronic control system is usually around 100°C. Using 0°C high-grade cold energy to cool a 100°C electronic control motor results in significant energy waste.

Detailed Implementation

[0050] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0051] Hereinafter, with reference to the accompanying drawings, a compressor 100 according to an embodiment of the present application will be described.

[0052] As shown in Figures 1-14, the compressor 100 according to an embodiment of this application includes: a compression chamber 213 and a cooling channel 13. The compression chamber 213 is used to compress refrigerant; the cooling channel 13 is isolated from the compression chamber 213 and is used to circulate coolant.

[0053] First, as shown in Figures 1-4, the compressor 100 includes a compression chamber 213 and a cooling channel 13. The compression chamber 213 can draw in refrigerant and compress it, and then discharge the compressed refrigerant outward. The cooling channel 13 is isolated from the compression chamber 213. The cooling channel is used to circulate coolant, which can cool the components inside the compressor 100 so that the compressor 100 can operate normally.

[0054] According to the embodiments of this application, the compressor 100 can be efficiently cooled by coolant to improve the operating stability of the compressor 100. The waste heat generated by the compressor 100 during operation will not affect the refrigerant, which helps to reduce exergy loss and improve energy utilization, thereby improving the overall performance of the compressor 100.

[0055] In some embodiments of this application, the compressor 100 of this application embodiment further includes: an electric assembly 1, the electric assembly 1 including a housing assembly 11, and a cooling channel 13 provided inside the housing assembly 11.

[0056] For example, referring to Figures 1-4, the compressor 100 includes an electric assembly 1, which includes a housing assembly 11. A cooling channel 13 is provided inside the side wall of the housing assembly 11. The cooling channel 13 has a coolant inlet 133 and a coolant outlet 134. Coolant can flow into the cooling channel 13 from the coolant inlet 133 and flow out from the coolant outlet 134. The coolant flowing into the cooling channel 13 is used to cool the compressor 100. This allows for sufficient cooling of the compressor 100, which helps improve the operational stability of the compressor 100.

[0057] In some embodiments of this application, as shown in Figures 1-4, the electric powertrain 1 further includes a motor assembly 12, which is disposed within the housing assembly 11. The motor assembly 12 includes a motor 121 and a crankshaft 122. The motor 121 cooperates with the crankshaft 122 to drive the crankshaft 122 to rotate, thereby driving the compressor 100 to operate. The coolant flowing into the cooling channel 13 is used to cool the motor assembly 12. This allows for efficient cooling of the motor assembly 12, which helps improve the operational stability of the compressor 100.

[0058] In some embodiments of this application, the electric powertrain 1 further includes an electronic control component 14, which is electrically connected to the motor assembly 12 for selectively controlling the operation of the motor assembly 12, and is disposed within the housing assembly 11. This allows the coolant in the cooling channel 13 to cool the electronic control component 14, preventing the waste heat from the electronic control component 14 from affecting the refrigerant.

[0059] In some embodiments of this application, as shown in Figures 3-4, the cooling channel 13 flows through the electronic control component 14 and the motor component 12 respectively for heat exchange with them. Here, "flows through" means that the cooling channel 13 passes through the portions of the housing component 11 corresponding to the electronic control component 14 and the motor component 12. This arrangement improves the cooling effect of the coolant on the electronic control component 14 and the motor component 12, thereby enhancing the operational stability of the compressor 100.

[0060] In some embodiments of this application, as shown in Figures 3-4, the housing assembly 11 has a spaced-apart electrical control cavity 113 and a motor cavity 114. The electrical control assembly 14 is installed in the electrical control cavity 113, and the motor assembly 12 is installed in the motor cavity 114. This arrangement separates the electrical control assembly 14 and the motor assembly 12, reducing the impact of the motor assembly 12 on the electrical control assembly 14 during operation, improving the stability of the electrical control assembly 14, reducing heat accumulation, lowering the temperature, and improving the operational stability of the compressor 100.

[0061] In some embodiments of this application, as shown in Figures 3-5 and 9, the compressor 100 further includes a pump assembly 2, which is connected to the housing assembly 11. The pump assembly 2 includes a compression component 21, which is used to draw in and compress refrigerant, and then discharge the compressed refrigerant outward. The housing assembly 11 includes a housing 111 and a base 112. The base 112 is located at the end of the housing 111 opposite to the pump assembly 2 and is connected to the housing 111. An electronic control chamber 113 is provided in the base 112, and a motor chamber 114 is provided in the housing 111. The cooling channel 13 includes a first channel 131 and a second channel 132. The first channel 131 is located in the base 112, and the coolant flowing in the first channel 131 is used to cool the electronic control component 14. The second channel 132 is located in the housing 111, and the coolant flowing in the second channel 132 is used to cool the motor assembly 12. Therefore, the electronic control component 14 and the motor component 12 can be cooled separately, which helps to improve the cooling effect.

[0062] In some embodiments of this application, as shown in Figures 3-5 and 9, the first flow channel 131 and the second flow channel 132 can be connected so that the first flow channel 131 and the second flow channel 132 can share the coolant inlet 133 and the coolant outlet 134. This simplifies the flow channels and reduces the structural complexity of the electric assembly 1.

[0063] In some embodiments of this application, as shown in Figures 3-5 and 9, a first flow channel 131 may be located upstream of a second flow channel 132. The first flow channel 131 is provided with a coolant inlet 133, which is located on the outer peripheral wall of the base 112. The second flow channel 132 is provided with a coolant outlet 134, which is located on the outer peripheral wall of the housing 111.

[0064] Specifically, coolant can flow into the first flow channel 131 from the coolant inlet 133. After exchanging heat with the electronic control component 14, the coolant flowing into the first flow channel 131 flows into the second flow channel 132. The coolant flowing into the second flow channel 132 exchanges heat with the motor component 12 and flows out from the coolant outlet 134.

[0065] Understandably, since the thermal stability of the electronic control component 14 is relatively poor, by setting the coolant to cool the electronic control component 14 first and then the motor component 12, the cooling effect can be guaranteed and the operating stability of the compressor 100 can be improved.

[0066] In some embodiments of this application, the base 112 is provided with a receiving groove 1121, which is formed as at least part of the motor cavity 114. The first flow channel 131 includes an inlet section 1311, an electronically controlled cooling section 1312, and an outlet section 1313. The electronically controlled cooling section 1312 is disposed on the bottom wall of the receiving groove 1121 and is used for heat exchange with the electronically controlled assembly 14. The inlet section 1311 is connected between the coolant outlet 134 and one end of the electronically controlled cooling section 1312. The outlet section 1313 is used to connect the other end of the electronically controlled cooling section 1312 to the second flow channel 132.

[0067] For example, as shown in Figures 3-6, the base 112 is provided with a receiving groove 1121 on the side facing the housing 111. The receiving groove 1121 is formed as at least part of the motor cavity 114. The bottom wall of the receiving groove 1121 is used to separate the electronic control cavity 113 and the motor cavity 114. The electronic control assembly 14 is adapted to be installed in the electronic control cavity 113 at the side wall of the receiving groove 1121 corresponding to the receiving groove 1121.

[0068] The first flow channel 131 may include an inlet section 1311, an electrically controlled cooling section 1312, and an outlet section 1313. The electrically controlled cooling section 1312 is located on the bottom wall of the receiving tank 1121, extends along the arrangement direction of the electrically controlled components 14, and is used for heat exchange with the electrically controlled components 14. The inlet section 1311 connects the coolant outlet 134 and one end of the electrically controlled cooling section 1312. One end of the outlet section 1313 connects to the other end of the electrically controlled cooling section 1312, and the other end forms an outlet 1124, which is used to connect with the second flow channel 132.

[0069] The above settings can make the layout of the first flow channel 131 more reasonable, which helps to ensure the cooling effect of the first flow channel 131 on the electronic control component 14 and improves the reliability of the compressor 100.

[0070] In some embodiments of this application, as shown in Figures 5-6, the housing assembly 11 further includes a base cover plate 115. The bottom wall of the receiving groove 1121 is provided with a flow channel groove 1122. The base cover plate 115 is matched with the flow channel groove 1122 and is used to install on the bottom wall of the receiving groove 1121, such as by fixing the base cover plate 115 to the bottom wall of the receiving groove 1121 with screws. The base cover plate 115 and the base 112 are used to define the electrically controlled cooling section 1312 at the flow channel groove 1122. This reduces the molding difficulty of the first flow channel 131 and lowers the processing cost of the compressor 100.

[0071] In some embodiments of this application, as shown in FIG5, a sealing gasket 4 may be provided between the base cover plate 115 and the bottom wall of the base 112. The sealing gasket 4 is arranged around the flow channel groove 1122 and is used to seal the electronically controlled cooling section 1312. This can improve the sealing performance of the electronically controlled cooling section 1312 and help reduce the probability of coolant leakage.

[0072] In some embodiments of this application, as shown in Figures 4 and 7, the second flow channel 132 includes multiple sub-flow channels 1321. These sub-flow channels 1321 are spaced apart circumferentially along the housing 111 and are all connected to the coolant outlet 134. This allows the coolant to flow through the multiple sub-flow channels 1321 to the coolant outlet 134, thereby enabling the coolant to cool the motor assembly 12 from different locations. This ensures effective cooling of the motor assembly 12 and improves the temperature uniformity of the motor assembly 12.

[0073] In some embodiments of this application, the second flow channel 132 further includes a turning flow channel 1322, which extends circumferentially along the housing 111. The same end of two adjacent sub-flow channels 1321 is connected through the turning flow channel 1322 to connect multiple sub-flow channels 1321 in series. The two sub-flow channels 1321 located on both sides are respectively connected to the first flow channel 131 and the coolant outlet 134.

[0074] For example, referring to Figures 4-7, multiple sub-channels 1321 can be arranged in parallel. The first channel 131 includes a turning channel 1322, which extends circumferentially along the housing 111. One end of the middle sub-channel 1321 is connected to the same end of an adjacent sub-channel 1321 through the turning channel 1322, and the other end is connected to the same end of another adjacent sub-channel 1321 through the turning channel 1322, so that multiple sub-channels 1321 can be arranged in series. The two sub-channels 1321 at both ends can be connected to the first channel 131 and the coolant outlet 134 respectively, so that the coolant can flow through multiple sub-channels 1321 sequentially. This simplifies the second channel 132 and reduces the structural complexity of the housing 111.

[0075] In some embodiments of this application, as shown in Figures 4, 6 and 10, a flow channel 1123 may be provided on the side wall of the base 112 corresponding to the housing 111. The flow channel 1123 extends circumferentially along the housing 111, and is opposite to the sub-flow channel 1321. The flow channel 1123 is used to define at least a portion of the turning flow channel 1322.

[0076] With the above configuration, the space inside the base 112 can be fully utilized, and the coverage of the second flow channel 132 can be increased so that the second flow channel 132 can cool the base 112, which is beneficial to improving the cooling effect of the coolant on the motor assembly 12 and also facilitates the lightweight design of the base 112.

[0077] Of course, this application is not limited to this. As shown in Figures 8 and 11, a diversion channel 1322 located at the end of the housing 111 opposite to the pump body assembly 2 can also be formed inside the housing 111. The base 112 is formed as a sealing surface 1125 corresponding to the side wall of the housing 111. The diversion channel 1322 has an opening, and the sealing surface 1125 is used to seal the diversion channel 1322 located at the end of the housing 111 opposite to the pump body assembly 2. Thus, the housing assembly 11 can be made more compact in axial dimensions along the crankshaft 122.

[0078] In some embodiments of this application, as shown in Figures 5 and 10, a diversion channel 1322 located at one end of the housing 111 near the pump assembly 2 can be formed within the housing 111, allowing the bracket 31 to seal the opening of the diversion channel 1322 at the end of the housing 111 near the pump assembly 2. This reduces the processing difficulty of the second channel 132.

[0079] Of course, this application is not limited to this. As shown in Figure 11, a flow channel 1123 can also be provided on the side wall of the bracket 31 corresponding to the housing 111. The flow channel 1123 extends circumferentially along the housing 111, and is opposite to the sub-flow channel 1321. The flow channel 1123 is used to define at least a portion of the turning flow channel 1322. This is beneficial for meeting different design requirements.

[0080] In some embodiments of this application, as shown in FIG6, the bottom wall of the flow channel 1123 can be constructed as an arc shape. This improves the flow guiding effect of the flow channel 1123.

[0081] In some embodiments of this application, the surface roughness of the inner wall of the flow channel 1123 can be set to a range of Ra0.8-Ra6.4. This setting reduces the flow resistance of the coolant within the second flow channel 132, thereby increasing the coolant's flow velocity.

[0082] Preferably, the surface roughness of the inner wall of the flow channel 1123 can be set to Ra 3.2. This helps to balance cost and flow resistance, improving the design rationality of the compressor 100.

[0083] In some embodiments of this application, the width of the sub-channel 1321 along the thickness direction of the housing 111 can be set to a range of 2mm-8mm, such as 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc. Preferably, the width of the sub-channel 1321 along the thickness direction of the housing 111 can be set to a range of 4mm-6mm. This setting reduces the molding difficulty of the sub-channel 1321, ensures sufficient structural strength of the housing 111, and improves the flow stability of the coolant within the sub-channel 1321.

[0084] In some embodiments of this application, on the same cross-section, the ratio of the length of the sub-channel 1321 along the circumferential direction of the housing 111 to the width of the sub-channel 1321 along the thickness direction of the housing 111 can be set to a range of 0.5-3. That is, the ratio of the length of the sub-channel 1321 along the circumferential direction of the housing 111 to the width of the sub-channel 1321 along the thickness direction of the housing 111 can be greater than or equal to 0.5 and less than or equal to 3, such as 0.5, 1, 1.5, 2, 2.5, 3, etc. This optimizes the flow resistance of the sub-channel 1321 and improves the flow stability of the coolant.

[0085] Preferably, the ratio of the length of the sub-channel 1321 along the circumferential direction of the housing 111 to the width of the sub-channel 1321 along the thickness direction of the housing 111 can be set to a range of 1-2.

[0086] In some embodiments of this application, as shown in FIG5, a sealing gasket 4 may be provided at least one end of the housing 111. Exemplarily, a sealing gasket 4 may be provided at the end of the housing 111 facing the pump assembly 2, with the sealing gasket 4 sandwiched between the housing 111 and the bracket 31. The sealing gasket 4 can seal the motor cavity 114, and together with the bracket 31, it can seal the opening of the second flow channel 132 facing the pump assembly 2. Alternatively, a sealing gasket 4 may be provided at the end of the housing 111 away from the pump assembly 2, with the sealing gasket 4 sandwiched between the housing 111 and the base 112. The sealing gasket 4 can seal the motor cavity 114, and it can also seal the opening of the second flow channel 132 facing the base 112. Alternatively, sealing gaskets 4 may be provided at both ends of the housing 111; this application does not limit this. Therefore, the overall reliability of the compressor 100 can be improved.

[0087] In some embodiments of this application, the sealing gasket 4 includes a skeleton and an elastic layer, with the elastic layer wrapping around the outside of the skeleton. The skeleton can be made of metal, and the elastic layer can be made of rubber. Preferably, the skeleton can be made of stainless steel, and the elastic layer can be made of hydrogenated nitrile rubber or nitrile rubber. This improves the structural stability of the sealing gasket 4 and ensures its sealing effect.

[0088] In some embodiments of this application, the compressor 100 of this application embodiment further includes: a pump body assembly 2, the pump body assembly 2 is connected to the housing assembly 11, the pump body assembly 2 includes a compression component 21, the compression component 21 is provided with a compression chamber 213, the motor assembly 12 is connected to the compression component 21 to drive the moving scroll 212 in the compression component 21 to move, and the pump body assembly 2 has a refrigerant inlet 214 and a refrigerant outlet 222 communicating with the compression chamber 213.

[0089] For example, referring to Figures 1-4, the compressor 100 includes a pump body assembly 2 and a partition assembly 3. The pump body assembly 2 is connected to the housing assembly 11. The pump body assembly 2 includes a compression component 21. The compression component 21 has a compression chamber 213. The pump body assembly 2 has a refrigerant inlet 214 and a refrigerant outlet 222. When the compression component 21 is running, the compression component 21 can draw refrigerant into the compression chamber 213 through the refrigerant inlet 214 and compress it, and then discharge the compressed refrigerant from the refrigerant outlet 222.

[0090] The partition assembly 3 includes a bracket 31, which is connected to the housing assembly 11, such as by screws. The bracket 31 is located between the electric assembly 1 and the pump body assembly 2 and is used to separate the electric assembly 1 and the pump body assembly 2 to avoid mutual interference between the motor assembly 12 and the compression component 21. The crankshaft 122 can pass through the bracket 31 and is connected to the moving scroll 212 in the compression component 21. The motor assembly 12 can be used to drive the moving scroll 212 to run, thereby ensuring that the compression component 21 can stably compress the refrigerant.

[0091] The above configuration allows the motor assembly 12 to be separated from the refrigerant, thus preventing the waste heat of the motor 121 from heating the refrigerant. This reduces exergy loss, improves energy efficiency, ensures the effective intake flow of the compression component 21, eliminates the risk of liquid refrigerant accumulating in the housing assembly 11, and improves the insulation withstand voltage of the compressor 100. Under high voltage conditions, the insulation withstand voltage level of the motor assembly 12 can be downgraded compared to existing compressors 100, which is beneficial for cost control of the compressor 100.

[0092] Of course, this application is not limited to this. The compression chamber 213 may also include a motor chamber 114 and an electronic control chamber 113, located upstream of the compression chamber 213. Refrigerant can flow through the motor assembly 12 and the electronic control assembly 14 to cool them. This improves the cooling efficiency of the motor assembly 12 and the electronic control assembly 14, thus enhancing the operational stability of the compressor 100.

[0093] In some embodiments of this application, as shown in FIG2, the compression component 21 further includes a stationary scroll 211, which is located on the side of the moving scroll 212 away from the electric assembly 1. The stationary scroll 211 and the moving scroll 212 cooperate to define a compression chamber 213. The stationary scroll 211 is provided with a refrigerant inlet 214, which communicates with the compression chamber 213. The pump assembly 2 also includes a high-pressure housing 22, which is located on the side of the stationary scroll 211 away from the electric assembly 1 and connected to the stationary scroll 211. The high-pressure housing 22 is provided with a high-pressure chamber 221 and a refrigerant outlet 222 communicating with the high-pressure chamber 221. The compression chamber 213 communicates with the refrigerant outlet 222 through the high-pressure chamber 221.

[0094] Specifically, when the crankshaft 122 drives the driven scroll 212 to move relative to the stationary scroll 211, the refrigerant can flow into the compression chamber 213 from the refrigerant inlet 214 and be compressed. After compression, the compression component 21 can discharge the compressed refrigerant into the high-pressure chamber 221. The refrigerant undergoes gas-liquid separation in the high-pressure chamber 221 to separate the lubricating oil. Then, the refrigerant can flow out from the refrigerant outlet 222 to the outside of the compressor 100.

[0095] The above settings can shorten the refrigerant flow path, reduce flow resistance, simplify the structure of pump assembly 2, and improve the design rationality of compressor 100.

[0096] In some embodiments of this application, as shown in FIG3, the partition assembly 3 further includes a bearing 32, a sealing ring 33, and a sealing ring baffle 34. The bracket 31 has an installation space on the side facing the pump body assembly 2. The bearing 32 is installed in the installation space and is used to support the crankshaft 122. The sealing ring 33 is sleeved on the outside of the crankshaft 122 and located on the side of the bearing 32 closer to the electric assembly 1. The sealing ring 33 is used to seal the gap between the bracket 31 and the crankshaft 122 to prevent lubricating oil from flowing into the motor cavity 114. The sealing ring baffle 34 is located on the side of the sealing ring 33 away from the motor cavity 114. The sealing ring baffle 34 is used to limit the sealing ring 33 to ensure the sealing effect of the sealing ring 33.

[0097] With the above settings, the electric assembly 1 and the pump assembly 2 can be completely separated, further reducing the impact of the waste heat of the motor 121 on the refrigerant and improving the design rationality of the compressor 100.

[0098] This application also proposes a thermal management system 1000.

[0099] As shown in Figure 13, the thermal management system 1000 according to an embodiment of this application includes: a first circulation path 200, a second circulation path 300, and a compressor 100 according to any of the above embodiments. The compression chamber 213 is connected to the first circulation path 200 to form a circulation loop. The first circulation path 200 includes a condenser 201, a throttling device 202, and an evaporator 203 connected in sequence. Compressed refrigerant can flow from the compression chamber 213 to the condenser 201 and release heat within the condenser 201. The refrigerant after releasing heat can flow through the throttling device 202 to the evaporator 203, where it expands and absorbs heat. The refrigerant after absorbing heat then flows back to the compression chamber 213. The second circulation passage 300 is connected to the cooling channel 13 to form a circulation loop. The second circulation passage 300 includes a water pump 301 and a heat exchanger 302. The water pump 301 can drive the coolant to circulate between the second circulation passage 300 and the cooling channel 13. The cooling channel 13 is used to cool the compressor 100, and the heat exchanger 302 is used to exchange heat with the outside to cool the coolant.
