The housing component includes a first housing and an end component. The first housing has a first end and a second end at its axial ends. The end component is disposed at the first end, forming a receiving cavity between the end component and the first housing. The receiving cavity is used to accommodate the compression component of the electric compressor, and the end component is located on one axial side of the compression component. An oil separator chamber is formed within the side wall of the first housing.

Technical Field

[0001] This invention relates to the field of compressor technology, and in particular to a housing component of an electric compressor, an electric compressor, an air conditioning system, and a vehicle. Background Technology

[0002] Electric compressors are core components of vehicle refrigeration equipment. They are high-efficiency, low-noise, and stable-operating positive displacement compressors, widely used in automotive air conditioning systems as third-generation vehicle compressors. In recent years, with the development of new energy vehicles, the requirements for noise, vibration, and durability of automotive air conditioning compressors have further increased. Related technologies indicate that the oil separator chamber of traditional compressors is usually located at the end of the housing, requiring thickening or extending the end of the housing, resulting in a larger axial dimension of the housing, which is not conducive to layout and leaves room for improvement. Summary of the Invention

[0013] According to some embodiments of the present invention, in the housing component of an electric compressor, one end of the length of the oil separator extends through the end face of the first end to form a first perforation, and / or the other end of the length of the oil separator extends through the end face of the second end to form a second perforation.

[0015] According to some embodiments of the present invention, in the housing component of an electric compressor, the other end of the length of the oil separator chamber does not penetrate the end face of the second end.

[0041] Embodiments of the present invention 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 are only used to explain the present invention, and should not be construed as limiting the present invention.

[0042] Hereinafter, with reference to the accompanying drawings, a housing component 100 of an electric compressor according to an embodiment of the present invention will be described.

[0043] like Figures 1-6 As shown, the housing component 100 of the electric compressor according to an embodiment of the present invention includes a first housing 1 and an end component 2. The first housing 1 has a first end 1A and a second end 1B at its two axial ends, respectively. The end component 2 is disposed at the first end 1A, so that a receiving cavity 14 is formed between the end component 2 and the first housing 1. The receiving cavity 14 is used to receive the compression component 200 of the electric compressor 300, and the end component 2 is located on one axial side of the compression component 200. An oil separator 11 is formed in the side wall of the first housing 1. The length direction of the oil separator 11 extends along the direction from the first end 1A to the second end 1B, and one end of the length of the oil separator 11 has an oil separator outlet 111, and the other end of the length has an oil separator return port 112.

[0044] Therefore, by setting the length direction of the oil separator 11 to extend from the first end 1A to the second end 1B, there is no need to thicken or extend the second end 1B to reserve processing space for the oil separator 11, so that the axial length of the first housing 1 is shortened, making the overall structure of the housing component 100 more compact and small.

[0045] For example, refer to Figures 1-5As shown, the electric compressor 300 is provided with a housing component 100, which includes a first housing 1 and an end component 2. The axis of the first housing 1 extends laterally (i.e., in the horizontal direction or generally horizontal direction). The two axial ends of the first housing 1 are respectively designated as a first end 1A and a second end 1B. The first housing 1 forms a cavity structure that is open toward the first end 1A. The end component 2 is conformally arranged relative to the open end of the first housing 1. The end component 2 can be installed to the first end 1A of the first housing 1 and defines a receiving cavity 14 between the first housing 1 and the end component 2. The electric compressor 300 is also provided with a compression component 200, which is adapted to be installed in the receiving cavity 14 and is arranged axially opposite to the end component 2, so that the end component 2 is located on the axial side of the compression component 200, so that the end component 2 can limit the compression component 200. The compression component 200 is used to draw in low-pressure refrigerant from outside the housing component 100 and compress it. The high-pressure refrigerant formed after compression can be discharged from the exhaust port 201 of the compression component 200 and flow into the receiving cavity 14 of the housing component 100.

[0046] The first housing 1 has an oil separator chamber 11 formed in the side wall, which is connected to the receiving cavity 14. The high-pressure refrigerant flowing into the receiving cavity 14 is adapted to flow into the oil separator chamber 11 and along the peripheral wall of the oil separator chamber 11, so that the high-pressure refrigerant can undergo gas-liquid separation to separate gaseous refrigerant and lubricating oil. The length of the oil separator chamber 11 extends from the first end 1A to the second end 1B, and one end of the oil separator chamber 11 has an oil separator outlet 111, which is used to communicate with the outside of the housing component 100. The separated gaseous refrigerant can flow to the outside of the housing component 100 through the oil separator outlet 111. The other end of the oil separator chamber 11 has an oil separator return port 112, which is connected to the receiving cavity 14. The separated lubricating oil can flow to the receiving cavity 14 through the oil separator return port 112.

[0047] In the specific working process, when the electric compressor 300 is powered on and running normally, the low-pressure refrigerant can be drawn in and compressed by the compression component 200 to form high-pressure refrigerant. The compression component 200 of the electric compressor 300 is adapted to discharge the compressed high-pressure refrigerant into the oil separator chamber 11. The high-pressure refrigerant flowing into the oil separator chamber 11 can flow along the inner peripheral wall of the oil separator chamber 11 to achieve gas-liquid separation. The separated gaseous refrigerant is discharged to the outside of the housing component 100 through the oil separator outlet 111. The separated lubricating oil can flow along the inner peripheral wall of the oil separator chamber 11 to the oil separator return port 112, so that it can flow into the receiving cavity 14 from the oil separator return port 112.

[0048] It is understandable that by setting the length direction of the oil separator 11 to extend from the first end 1A to the second end 1B, there is no need to thicken or extend the second end 1B to reserve processing space for the oil separator 11. This makes the length of the first housing 1 along the axial direction shorter, so that the overall structure of the housing component 100 becomes compact and small. In particular, when the axis of the first housing 1 extends in a horizontal or slightly inclined horizontal direction, shortening the axial length of the first housing 1 can effectively reduce the footprint of the housing component 100.

[0049] According to an embodiment of the present invention, the housing component 100 of the electric compressor has an oil separator 11 provided on the side wall of the first housing 1, and the length direction of the oil separator 11 is set to extend from the first end 1A to the second end 1B. This eliminates the need to thicken or extend the second end 1B to reserve processing space for the oil separator 11, thereby shortening the axial length of the first housing 1. This makes the overall structure of the housing component 100 more compact and small, which is beneficial for realizing the miniaturization design of the housing component 100.

[0050] In some embodiments of the present invention, the length centerline of the oil separator chamber 11 is inclined to the axis of the first housing 1, and the oil return port 112 is lower than the oil outlet 111. For example, referring to... Figure 1 As shown, the center line of the oil separator chamber 11 can be set to extend from the first end 1A to the second end 1B and slope downwards, with the center line of the oil separator chamber 11 forming a certain angle with the axis of the first housing 1. Specifically, an oil outlet 111 can be provided at the end of the oil separator chamber 11 facing the first end 1A, and an oil return port 112 can be provided at the end of the oil separator chamber 11 facing the second end 1B, so that the height of the oil return port 112 is lower than that of the oil outlet 111. In this way, when the high-pressure refrigerant separates the lubricating oil, the lubricating oil can flow along the inner wall of the oil separator chamber 11 to the oil outlet 111 under the action of gravity. This ensures the reliability of the lubricating oil return. Of course, the invention is not limited to this; for example, the center line of the oil separator chamber 11 can also be set parallel to the axis of the first housing 1, with the oil return port 112 at the same height as the oil outlet 111.

[0051] In some embodiments of the present invention, the first housing 1 has a refrigerant discharge port 12, and the oil separator outlet 111 communicates with the refrigerant discharge port 12. For example, see reference Figure 1 As shown, a refrigerant discharge hole 12 can be provided on the first housing 1. The refrigerant discharge hole 12 penetrates the first housing 1 radially and is used to connect the oil separator outlet 111 with the outside of the housing component 100. In this way, when the high-pressure refrigerant separates into gaseous refrigerant in the oil separator chamber 11, the gaseous refrigerant can flow out through the oil separator outlet 111 to the refrigerant discharge hole 12 and flow from the refrigerant discharge hole 12 to the outside of the housing component 100.

[0052] It is understandable that by directly machining the refrigerant discharge hole 12 on the first housing 1, there is no need to machine the refrigerant discharge hole 12 on other housings, making the overall structure simpler and the exhaust efficiency higher.

[0053] In some embodiments of the present invention, the refrigerant discharge port 12 and the oil separator outlet 111 are spaced apart along the axial direction of the first housing 1, and the oil separator outlet 111 and the refrigerant discharge port 12 are connected through an air outlet channel 13, at least a portion of which is formed on the first housing 1.

[0054] For example, refer to Figure 1 As shown, the refrigerant discharge port 12 and the oil separator outlet 111 can be spaced apart along the axial direction of the first housing 1. An exhaust channel 13 can be formed inside the side wall of the first housing 1, or the first housing 1 and the end component 2 can jointly define the exhaust channel 13. One end of the exhaust channel 13 communicates with the oil separator outlet 111, and the other end communicates with the refrigerant discharge port 12. Thus, when the high-pressure refrigerant separates into gaseous refrigerant in the oil separator chamber 11, the gaseous refrigerant can flow into the exhaust channel 13 through the oil separator outlet 111 and flow along the exhaust channel 13 towards the refrigerant discharge port 12, so as to be discharged from the refrigerant discharge port 12 to the outside of the housing component 100. This increases the travel distance of the gaseous refrigerant during the exhaust process, reduces noise during exhaust, improves the gas-liquid separation effect of the high-pressure refrigerant, and effectively prevents the gaseous refrigerant discharged from the oil separator outlet 111 from carrying lubricating oil.

[0055] Of course, the present invention is not limited to this. The present invention can also directly connect the exhaust port 201 of the compression component 200 to the oil separator chamber 11, allowing the high-pressure refrigerant to be directly discharged into the oil separator chamber 11. Furthermore, the oil separator outlet 111 can be connected to the receiving cavity 14, and the receiving cavity 14 can be connected to the refrigerant discharge hole 12. Thus, when the high-pressure refrigerant separates into gaseous refrigerant in the oil separator chamber 11, the gaseous refrigerant can flow into the receiving cavity 14 through the oil separator outlet 111 and from the receiving cavity 14 to the refrigerant discharge hole 12, and then be discharged from the refrigerant discharge hole 12 to the outside of the housing component 100. This reduces the processing difficulty of the first housing 1 and allows for further separation of the lubricating oil carried by the gaseous refrigerant into the receiving cavity 14, improving the gas-liquid separation effect of the high-pressure refrigerant.

[0056] In some embodiments of the present invention, the refrigerant discharge port 12 is disposed relative to the first end 1A and close to the second end 1B, the oil separator outlet 111 is disposed relative to the second end 1B and close to the first end 1A, and the gas outlet channel 13 includes: a first channel section 131, which is formed in the side wall of the first housing 1, and one end of the first channel section 131 penetrates the end face of the first end 1A and is closed by the end member 2, and the other end of the first channel section 131 extends toward the second end 1B and communicates with the refrigerant discharge port 12; and a second channel section 132, which is formed on the first housing 1 and / or the end member 2 and located at the first end 1A, and the second channel section 132 communicates with the oil separator outlet 111 and the first channel section 131.

[0057] For example, refer to Figure 1 As shown, the refrigerant discharge port 12 can be located near the second end 1B of the first housing 1, and the oil separator outlet 111 can be located near the first end 1A of the first housing 1. Simultaneously, an air outlet channel 13 can be provided, including a first channel section 131 and a second channel section 132. The first channel section 131 is formed within the side wall of the first housing 1 and extends axially along the first housing 1. The end of the first channel section 131 facing the second end 1B is used to communicate with the refrigerant discharge port 12. The other end of the first channel section 131 penetrates the end face of the first end 1A to open outwards, and the end component 2 can be used to seal the open end of the first channel section 131 to prevent air leakage.

[0058] Among them, such as Figure 1 As shown, the second channel section 132 can be disposed at the first end 1A of the first housing 1. The side of the second channel section 132 facing away from the second end 1B is open to the outside, and the end component 2 can be used to seal the open side of the second channel section 132 to prevent the second channel section 132 from leaking air. One end of the second channel section 132 is used to communicate with the first channel section 131, and the other end is used to communicate with the oil separator outlet 111 to realize the communication between the oil separator outlet 111 and the refrigerant discharge hole 12.

[0059] For example, refer to Figure 4 As shown, the second channel segment 132 can be disposed at one end of the end component 2 facing the first housing 1. The end component 2 can be provided with a bracket 23 and a gasket 24. The gasket 24 is disposed between the bracket 23 and the first end 1A of the first housing 1. The second channel segment 132 is disposed on the bracket 23 and is open on the side facing the gasket 24. The gasket 24 is used to close the open side of the second channel segment 132. One end of the second channel segment 132 is connected to the first channel segment 131, and the other end can be connected to the oil separator outlet 111 to realize the connection between the oil separator outlet 111 and the refrigerant discharge hole 12.

[0060] Of course, the present invention is not limited to this. For example, in other embodiments of the present invention, the end component 2 may only include the bracket 23 and not the gasket 24. In this case, the second channel section 132 is provided on the bracket 23 and is open to the side facing the first end 1A of the first housing 1. The first end 1A of the first housing 1 is used to close the open side of the second channel section 132. One end of the second channel section 132 is connected to the first channel section 131, and the other end can be connected to the oil separator outlet 111 to realize the connection between the oil separator outlet 111 and the refrigerant discharge hole 12.

[0061] In the specific working process, when the high-pressure refrigerant separates into gaseous refrigerant in the oil separator chamber 11, the gaseous refrigerant can flow into the second channel section 132 through the oil separator outlet 111, and then flow along the second channel section 132 to the first channel section 131, so as to flow from the first channel section 131 to the refrigerant discharge hole 12, and then be discharged from the refrigerant discharge hole 12 to the outside of the housing component 100. This increases the flow path of the gaseous refrigerant during exhaust, improving the gas-liquid separation effect of the high-pressure refrigerant.

[0062] It is understandable that by setting the refrigerant discharge hole 12 to be connected to the oil separator outlet 111 through the first channel section 131 and the second channel section 132, the location of the oil separator outlet 111 is more widely available. Furthermore, by setting the first channel section 131 and the second channel section 132 to be open outward, the first channel section 131 and the second channel section 132 are easier to process, thus reducing processing costs.

[0063] In some embodiments of the present invention, the refrigerant discharge hole 12 is disposed relative to the first end 1A and close to the second end 1B, and the oil separator outlet 111 is also disposed relative to the first end 1A and close to the second end 1B, and the oil separator outlet 111 is directly connected to the refrigerant discharge hole 12.

[0064] For example, refer to Figure 3 The refrigerant discharge port 12 can be located near the second end 1B of the first housing 1, and the oil separator outlet 111 can be located near the second end 1B of the first housing 1, so that the oil separator outlet 111 and the refrigerant discharge port 12 are arranged radially opposite to each other along the first housing 1, allowing the oil separator outlet 111 to be directly connected to the refrigerant discharge port 12. In this way, when the high-pressure refrigerant separates into gaseous refrigerant in the oil separator chamber 11, the gaseous refrigerant can flow directly into the refrigerant discharge port 12 through the oil separator outlet 111, and then be discharged from the refrigerant discharge port 12 to the outside of the housing component 100. This reduces the travel distance of the gaseous refrigerant during exhaust and improves the exhaust efficiency of the gaseous refrigerant.

[0065] In some embodiments of the present invention, the oil separator chamber 11 has an oil separator inlet 113 extending tangentially, and the end component 2 has a silencing groove 21, which is adapted to cooperate with the compression component 200 to form a silencing chamber, and the silencing groove 21 communicates with the oil separator inlet 113.

[0066] For example, refer to Figure 1 As shown, an oil inlet 113 can be provided on the inner peripheral wall of the oil separator chamber 11. The oil inlet 113 extends tangentially along the oil separator chamber 11 and connects the receiving chamber 14 to the oil separator chamber 11, allowing the high-pressure refrigerant flowing into the receiving chamber 14 to flow into the oil separator chamber 11 through the oil inlet 113. Simultaneously, the end component 2 is provided with a silencing groove 21 opening towards the receiving chamber 14. The silencing groove 21 cooperates with the compression component 200 to form a silencing chamber, which communicates with the oil inlet 113. The silencing chamber is used to reduce noise from the high-pressure refrigerant within the oil inlet 113. This reduces the exhaust noise of the refrigerant, improving user comfort.

[0067] In some embodiments of the present invention, the oil separator inlet 113 is disposed near the first end 1A relative to the second end 1B, wherein an air intake channel 22 is formed on the first housing 1 and / or the end component 2, and the silencing groove 21 is connected to the oil separator inlet 113 through the air intake channel 22, or the silencing groove 21 is connected to the oil separator inlet 113 through the receiving cavity 14.

[0068] For example, an oil inlet 113 can be provided at a position near the first end 1A of the first housing 1. An air intake passage 22 can be formed on the side wall of the first housing 1; or, as... Figure 1 As shown, an air intake channel 22 can be formed on the end component 2; alternatively, air intake channels 22 can be provided on both the side wall of the first housing 1 and the end component 2. The air intake channel 22 is used to connect the silencing groove 21 and the oil separator inlet 113. This facilitates a stable connection between the silencing groove 21 and the oil separator inlet 113, improving the noise reduction effect of the silencing cavity.

[0069] For example, such as Figure 3 As shown, an oil inlet 113 can be provided at a position near the first end 1A of the first housing 1, and a silencing groove 21 is provided on the end component 2. The silencing groove 21 and the compression component 200 define a silencing cavity, which is connected to the receiving cavity 14, so that the silencing cavity can be directly connected to the oil inlet 113 through the receiving cavity 14. This helps to reduce the processing difficulty of the first housing 1 and reduce the processing cost of the first housing 1.

[0070] In some embodiments of the present invention, one end of the length of the oil separator 11 extends through the end face of the first end 1A to form a first perforation 16, and / or the other end of the length of the oil separator 11 extends through the end face of the second end 1B to form a second perforation 17.

[0071] For example, the oil separator 11 can be configured to extend along the length direction from the first end 1A to the second end 1B. Specifically, one end of the oil separator 11 along its length direction can penetrate the end face of the first end 1A to form a first through hole 16 on the end face of the first end 1A; alternatively, one end of the oil separator 11 along its length direction can penetrate the end face of the second end 1B to form a second through hole 17 on the end face of the second end 1B; or alternatively, one end of the oil separator 11 along its length direction can penetrate the end face of the first end 1A to form a first through hole 16 on the end face of the first end 1A, and the other end of the oil separator 11 along its length direction can penetrate the end face of the second end 1B to form a first through hole 16 on the end face of the second end 1B. This allows the oil separator 11 to be processed from either the first through hole 16 or the second through hole 17, reducing the processing difficulty of the oil separator 11 and lowering the processing cost of the first housing 1.

[0072] In some embodiments of the present invention, a first through hole 16 is formed on the end face of the first end 1A, the first through hole 16 is closed by the end component 2, and an oil separator inner tube 15 is provided in the oil separator cavity 11. The oil separator inner tube 15 is adapted to be inserted or processed through the first through hole 16.

[0073] For example, the oil separator chamber 11 can be configured to extend along the length direction from the first end 1A to the second end 1B. One end of the oil separator chamber 11 along the length direction penetrates the end face of the first end 1A, forming a first through hole 16 on the end face of the first end 1A. The first through hole 16 is axially opposite to the end member 2 along the first housing 1, so that the end member 2 can close the first through hole 16. At the same time, an oil separator inner tube 15 can be installed in the oil separator chamber 11. At least a portion of the outer peripheral wall of the oil separator inner tube 15 is spaced apart from the inner peripheral wall of the oil separator chamber 11 to form an annular air inlet chamber 18. The air inlet chamber 18 is open toward the second end 1B, and the oil separator inlet 113 is adapted to communicate tangentially with the air inlet chamber 18. The inner cavity of the oil separator inner tube 15 forms an air outlet chamber 19, and the two ends of the air outlet chamber 19 are respectively connected to the oil separator chamber 11 and the oil separator outlet 111. In this way, when the electric compressor 300 discharges high-pressure refrigerant into the receiving cavity 14, the high-pressure refrigerant can flow tangentially into the intake cavity 18 through the oil separator inlet 113. The high-pressure refrigerant can flow around the inner tube 15 of the oil separator in the intake cavity 18 to achieve gas-liquid separation. The separated lubricating oil flows along the inner peripheral wall of the oil separator cavity 11 to the oil separator return port 112. The separated gaseous refrigerant can flow to the oil separator outlet 111 through the outlet cavity 19.

[0074] The oil separator inner tube 15 can be formed separately and installed into the oil separator cavity 11 through the first perforation 16. Alternatively, the oil separator inner tube 15 can be directly machined into the oil separator cavity 11 through the first perforation 16. This application does not impose any restrictions on this method. This reduces the processing difficulty and cost of the oil separator inner tube 15.

[0075] In some embodiments of the present invention, reference is made to... Figure 1 As shown, the other end of the oil separator chamber 11 does not penetrate the end face of the second end 1B. This arrangement ensures that the other end of the oil separator chamber 11 along its length is closed, preventing direct communication between the oil outlet 111 and the outside of the housing component 100. This improves the sealing performance of the oil separator chamber 11, reduces the possibility of lubricating oil leakage, and enhances the stability and reliability of the housing component 100.

[0076] In some embodiments of the present invention, a second through hole 17 is formed on the end face of the second end 1B, the second through hole 17 is closed by the sealing member 3, and an oil separator inner tube 15 is provided in the oil separator cavity 11. The oil separator inner tube 15 is adapted to be inserted or processed through the second through hole 17.

[0077] For example, refer to Figure 2 The oil separator chamber 11 can be configured to extend along the length direction from the first end 1A to the second end 1B. One end of the oil separator chamber 11 along the length direction penetrates the end face of the second end 1B, forming a second through hole 17 on the end face of the second end 1B. The second through hole 17 is suitable for installing a sealing member 3, which can seal the second through hole 17 to separate the oil separator chamber 11 from the outside of the housing component 100. An inner oil separator tube 15 is installed inside the oil separator chamber 11. Alternatively, the inner oil separator tube 15 can be formed separately and installed into the oil separator chamber 11 through the second through hole 17, or the inner oil separator tube 15 can be directly machined into the oil separator chamber 11 through the second through hole 17. This application does not limit this.

[0078] With the above configuration, the inner oil separator tube 15 can be inserted or processed through the second perforation 17, avoiding any restrictions on the size and arrangement of the oil separator outlet 111 by the inner oil separator tube 15, which facilitates the flexible arrangement of the oil separator outlet 111 and improves the reliability of the housing component 100.

[0079] In some embodiments of the present invention, a first through hole 16 is formed on the end face of the first end 1A, and the cross-sectional area S1 of the first through hole 16 is smaller than the cross-sectional area S2 of the second through hole 17. For example, refer to Figure 2As shown, the oil separator chamber 11 can be configured to extend along the length direction from the first end 1A to the second end 1B. One end of the oil separator chamber 11 along the length direction penetrates the end face of the first end 1A to form a first through hole 16 on the end face of the first end 1A, with a cross-sectional area of ​​S1. The other end penetrates the end face of the second end 1B to form a second through hole 17 on the end face of the second end 1B, with a cross-sectional area of ​​S2. The cross-sectional area S1 of the first through hole 16 is smaller than the cross-sectional area S2 of the second through hole 17. Therefore, when the inner oil separator tube 15 is installed into the oil separator chamber 11 through the second through hole 17, the inner oil separator tube 15 can be prevented from detaching from the oil separator chamber 11 at the first through hole 16, thus improving the installation stability of the inner oil separator tube 15.

[0080] The housing component 100 of an electric compressor according to some specific embodiments of the present invention will now be described.

[0081] Example 1

[0082] like Figure 1 As shown, the housing component 100 includes a first housing 1 and an end component 2. The axis of the first housing 1 extends laterally (i.e., horizontally or generally horizontally). The two axial ends of the first housing 1 are respectively designated as a first end 1A and a second end 1B. The first housing 1 forms a cavity structure open toward the first end 1A. The end component 2 is conformally disposed relative to the open end of the first housing 1. The end component 2 can be installed to the first end 1A of the first housing 1 and defines a receiving cavity 14 between the first housing 1 and the end component 2. A compression component 200 is adapted to be installed in the receiving cavity 14 and is disposed axially opposite to the end component 2, so that the end component 2 is located on one axial side of the compression component 200, so that the end component 2 can limit the compression component 200. The compression component 200 is used to draw in low-pressure refrigerant from outside the housing component 100 and compress it. The high-pressure refrigerant formed after compression can be discharged from the exhaust port 201 of the compression component 200 and flow into the receiving cavity 14 of the housing component 100.

[0083] The first housing 1 has an oil separator chamber 11 formed in the side wall. The oil separator chamber 11 extends along the length direction from the first end 1A to the second end 1B. The end of the oil separator chamber 11 facing the first end 1A along the length direction has an oil separator outlet 111, and the other end along the length direction has an oil separator return port 112. The height of the oil separator return port 112 is lower than that of the oil separator outlet 111. The oil separator chamber 11 also has an oil separator inner tube 15. An air inlet chamber 18 is defined between the oil separator inner tube 15 and the inner peripheral wall of the oil separator chamber 11. The oil separator inlet 113 connects the air inlet chamber 18 and the receiving chamber 14 tangentially. An air outlet chamber 19 is formed in the inner cavity of the oil separator inner tube 15 and is connected to the oil separator outlet 111. A refrigerant discharge hole 12 may be provided near the second end 1B, and an air outlet channel 13 may be formed on the side wall of the first housing 1. The air outlet channel 13 includes a first channel section 131 and a second channel section 132. The oil inlet 113 is adapted to communicate with the refrigerant discharge hole 12 by passing through the second channel section 132 and the first channel section 131 in sequence.

[0084] In the specific working process, when the electric compressor 300 is powered on and running normally, low-pressure refrigerant can be drawn in and compressed by the compression component 200 to form high-pressure refrigerant. The compression component 200 of the electric compressor 300 is adapted to discharge the compressed high-pressure refrigerant into the oil separator chamber 11. The high-pressure refrigerant flowing into the oil separator chamber 11 can flow into the intake chamber 18 through the oil separator inlet 113 and rotate around the inner tube 15 of the oil separator in the intake chamber 18 to achieve gas-liquid separation. The separated lubricating oil can flow along the inner peripheral wall of the oil separator chamber 11 to the oil separator return port 112, and then flow into the receiving chamber 14 from the oil separator return port 112. The separated gaseous refrigerant is discharged through the oil separator outlet 111 to the second channel section 132, and flows along the second channel section 132 and the first channel section 131 to the refrigerant discharge hole 12, and is discharged from the refrigerant discharge hole 12 to the outside of the housing component 100.

[0085] It should be noted that one end of the oil separator chamber 11 along its length penetrates the end face of the first end 1A to form a first perforation 16. The first perforation 16 is open outward and suitable for closure by the end component 2. One end of the oil separator chamber 11 along its length does not penetrate the end face of the second end 1B to remain closed, and the inner oil separator tube 15 can be installed into the oil separator chamber 11 through the first perforation 16. The end component 2 is provided with a silencing groove 21, which forms a silencing chamber with the compression component 200. The silencing chamber is connected to the oil separator inlet 113 through the air intake channel 22 to reduce noise during the exhaust process.

[0086] Example 2

[0087] like Figure 2As shown, the difference between this embodiment 2 and the above embodiment 1 is that: the other end of the oil separator chamber 11 along the length direction penetrates the end face of the second end 1B to form a second perforation 17 on the end face of the second end 1B. The second perforation 17 is open to the outside and is suitable for being sealed by the sealing member 3. The oil separator inner tube 15 can be installed into the oil separator chamber 11 through the second perforation 17. The cross-sectional area S1 of the first perforation 16 is set to be smaller than the cross-sectional area S2 of the second perforation 17 to prevent the oil separator inner tube 15 from detaching from the oil separator chamber 11 from the first perforation 16.

[0088] Example 3

[0089] like Figure 3 As shown, the difference between this embodiment three and the above embodiment one includes: an oil separator chamber 11 is formed in the side wall of the first housing 1. The length direction of the oil separator chamber 11 extends from the first end 1A to the second end 1B. The end of the oil separator chamber 11 facing the second end 1B along the length direction has an oil separator outlet 111, which is directly connected to the refrigerant discharge hole 12. The other end of the oil separator chamber 11 along the length direction has an oil separator return port 112. In this way, the separated gaseous refrigerant can be directly discharged to the refrigerant discharge hole 12 through the oil separator outlet 111 to the outside of the housing component 100. A silencing groove 21 can be provided on the end component 2. The silencing groove 21 is used to form a silencing cavity with the compression component 200. The silencing cavity is connected to the oil separator inlet 113 through the receiving cavity 14 to reduce noise during the exhaust process.

[0090] Example 4

[0091] like Figure 4 As shown, the difference between this embodiment four and the above embodiment one includes: the second channel segment 132 is provided at one end of the end component 2 facing the first housing 1. The end component 2 includes a bracket 23 and a gasket 24. The gasket 24 is provided between the bracket 23 and the first end 1A of the first housing 1. The second channel segment 132 is provided on the bracket 23 and is open on the side facing the gasket 24. The gasket 24 is used to close the open side of the second channel segment 132. One end of the second channel segment 132 is connected to the first channel segment 131, and the other end can be connected to the oil separator outlet 111 to realize the connection between the oil separator outlet 111 and the refrigerant discharge hole 12.

[0092] The present invention also proposes an electric compressor 300.

[0093] Reference Figure 5 As shown, the electric compressor 300 according to an embodiment of the present invention includes a compression component 200 and a housing component 100 of the electric compressor of any of the above embodiments.

[0094] For example, refer to Figures 1-5As shown, the electric compressor 300 includes a housing component 100 and a compression component 200. The housing component 100 includes a first housing 1 and an end component 2. The axis of the first housing 1 extends laterally (i.e., horizontally or generally horizontally). The two axial ends of the first housing 1 are respectively designated as a first end 1A and a second end 1B. The first housing 1 forms a cavity structure open towards the first end 1A. The end component 2 is conformally arranged relative to the open end of the first housing 1. The end component 2 can be installed to the first end 1A of the first housing 1 and defines a receiving cavity 14 between the first housing 1 and the end component 2. The compression component 200 is adapted to be installed in the receiving cavity 14 and is arranged axially opposite to the end component 2, so that the end component 2 is located on one axial side of the compression component 200, so that the end component 2 can limit and support the compression component 200. The compression component 200 is used to draw in low-pressure refrigerant from outside the housing component 100 and compress it. The high-pressure refrigerant formed after compression can be discharged from the exhaust port 201 of the compression component 200 and flows into the receiving cavity 14 of the housing component 100.

[0095] The first housing 1 has an oil separator chamber 11 formed in the side wall, which is connected to the receiving cavity 14. The high-pressure refrigerant flowing into the receiving cavity 14 is adapted to flow into the oil separator chamber 11 and along the peripheral wall of the oil separator chamber 11, so that the high-pressure refrigerant can undergo gas-liquid separation to separate gaseous refrigerant and lubricating oil. The length of the oil separator chamber 11 extends from the first end 1A to the second end 1B, and one end of the oil separator chamber 11 has an oil separator outlet 111, which is used to communicate with the outside of the housing component 100. The separated gaseous refrigerant can flow to the outside of the housing component 100 through the oil separator outlet 111. The other end of the length has an oil separator return port 112, which is connected to the receiving cavity 14. The separated lubricating oil can flow to the receiving cavity 14 through the oil separator return port 112.

[0096] In the specific working process, when the electric compressor 300 is powered on and running normally, the low-pressure refrigerant can be drawn in and compressed by the compression component 200 to form high-pressure refrigerant. The compression component 200 of the electric compressor 300 is adapted to discharge the compressed high-pressure refrigerant into the oil separator chamber 11. The high-pressure refrigerant flowing into the oil separator chamber 11 can flow along the inner peripheral wall of the oil separator chamber 11 to achieve gas-liquid separation. The separated gaseous refrigerant is discharged to the outside of the housing component 100 through the oil separator outlet 111. The separated lubricating oil can flow along the inner peripheral wall of the oil separator chamber 11 to the oil separator return port 112, so that it can flow into the receiving cavity 14 from the oil separator return port 112.

[0097] It is understandable that by setting the length direction of the oil separator 11 to extend from the first end 1A to the second end 1B, there is no need to thicken or extend the second end 1B to reserve processing space for the oil separator 11. This makes the length of the first housing 1 along the axial direction shorter, so that the overall structure of the housing component 100 becomes compact and small. In particular, when the axis of the first housing 1 extends in a horizontal or slightly inclined horizontal direction, shortening the axial length of the first housing 1 can effectively reduce the footprint of the housing component 100.

[0098] It should be noted that the type of compression component 200 in this application is not limited, and can be configured as rotary or scroll type, etc. Among them, the rotary compression component 200 typically includes a cylinder and a piston, the piston being rotatably disposed in the cylinder, and the piston being driven by the crankshaft of the through end component 2; while the scroll compression component 200 typically includes a stationary scroll and a moving scroll, with the drive shaft connected to the moving scroll.

[0099] According to an embodiment of the present invention, the electric compressor 300 has an oil separator 11 provided on the side wall of the first housing 1, and the length direction of the oil separator 11 is set to extend from the first end 1A to the second end 1B. This eliminates the need to thicken or extend the second end 1B to reserve processing space for the oil separator 11, thereby shortening the axial length of the first housing 1. This makes the overall structure of the housing component 100 more compact and smaller, which is conducive to the miniaturization design of the housing component 100, reducing the size of the electric compressor 300, and facilitating the installation layout of the electric compressor 300.

[0100] The present invention also proposes an air conditioning system 400.

[0101] Reference Figure 6 As shown, the air conditioning system 400 according to an embodiment of the present invention includes an electric compressor 300 of any of the above embodiments. By providing an oil separator 11 on the side wall of the first housing 1 and setting the length direction of the oil separator 11 to extend from the first end 1A to the second end 1B, it is not necessary to thicken or extend the second end 1B to reserve processing space for the oil separator 11. This shortens the axial length of the first housing 1, making the overall structure of the housing component 100 more compact and smaller, which is conducive to realizing the miniaturization design of the housing component 100, reducing the size of the electric compressor 300, and thus reducing the overall size of the air conditioning system 400.

[0102] The present invention also proposes a vehicle 500.

[0103] Reference Figure 6As shown, the vehicle 500 according to an embodiment of the present invention includes: a vehicle body and an air conditioning system 400 mounted on the vehicle body, wherein the air conditioning system 400 is any of the air conditioning systems 400 described above. By providing an oil separator chamber 11 on the side wall of the first housing 1 and setting the length direction of the oil separator chamber 11 to extend from the first end 1A to the second end 1B, it is not necessary to thicken or extend the second end 1B to reserve processing space for the oil separator chamber 11, thereby shortening the axial length of the first housing 1. This makes the overall structure of the housing component 100 more compact and smaller, which is conducive to realizing the miniaturization design of the housing component 100, reducing the size of the electric compressor 300, thereby reducing the overall size of the air conditioning system 400 and improving the rationality of the layout of the vehicle 500.

[0104] In this embodiment, vehicle 500 can be a new energy vehicle. In some embodiments, the new energy vehicle can be a pure electric vehicle with an electric motor as the main driving force. In other embodiments, the new energy vehicle can also be a hybrid vehicle with both an internal combustion engine and an electric motor as the main driving force. Regarding the internal combustion engine and electric motor mentioned in the above embodiments that provide driving power for the new energy vehicle, the internal combustion engine can use gasoline, diesel, hydrogen, etc. as fuel, and the way to provide electrical energy to the electric motor can be a power battery, hydrogen fuel cell, etc., without special limitation.
