[0032] In order to better understand the technical solutions of the application, the embodiments of the application are described in detail below with reference to the drawings.

[0033] It should be clear that the described embodiments are only some of the embodiments of the application, not all. Based on the technical solutions in the application, all other technical solutions obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the application.

[0034] In order to reduce the assembly difficulty of the separation barrier, the application provides a compressor, please refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7 The compressor comprises a housing 1, an exhaust cover 2 and a static scroll 41, the housing 1 has a mounting cavity 10, the static scroll 41 is at least partially located in the mounting cavity 10, the exhaust cover 2 is connected with the housing 1, the compressor 100 has an exhaust cavity 110, the exhaust cavity 110 is located between the exhaust cover 2 and the static scroll 41; the exhaust cavity 110 comprises a first cavity 110a and a second cavity 100b, the compressor 100 comprises a separation barrier S, the separation barrier S is at least partially located between the first cavity 110a and the second cavity 100b, one end of the separation barrier S is connected with one of the exhaust cover 2 and the static scroll 41, the other end of the separation barrier S has a gap L with the other one of the exhaust cover 2 and the static scroll 41, the compressor 100 has a separation channel 110c, the separation channel 110c communicates with the first cavity 110a and the second cavity 100b, and the separation channel 110c comprises the gap L. At least part of the separation channel 110c is formed by the gap L on one side of the separation barrier S, which can reduce the assembly difficulty of the separation barrier S.

[0035] When the compressor is operating, the high-pressure refrigerant and lubricating oil mixture is discharged from the scroll exhaust port 410 of the stationary scroll 41 into the first chamber 110a, and then enters the second chamber 100b via the gap L. (See also...) Figure 6 In some embodiments, taking a separation baffle S as an example, where the separation baffle S is connected to the exhaust cover 2 and forms a gap L between it and the stationary scroll 41, when the high-pressure refrigerant and lubricating oil mixture enters the second chamber 100b through the gap L, the increased flow area reduces the flow velocity to a certain extent, which is beneficial for oil-gas separation. The separated oil can adhere to the outer wall of the separation baffle S and the inner wall of the housing 1 where the second chamber 100b is located. The separated oil eventually drips off under the action of gravity and finally returns to the compressor 100 through the oil return channel T, thus realizing oil return. The oil return channel T is connected to the second chamber 100b. The compressor is arranged in the following manner during operation: Figure 6 As shown in the diagram, the return oil channel T is in a lower position in the direction of gravity, which is conducive to oil return.

[0036] Of course, in some other embodiments, there is one separation baffle S, and the separation baffle S is connected to the stationary vortex disk 41. When the high-pressure refrigerant and lubricating oil mixture is ejected from the vortex disk exhaust port 410 of the stationary vortex disk 41 along the radial side of the stationary vortex disk 41 into the first chamber 110a, it is first blocked by the separation baffle S, thereby facilitating the oil-gas separation effect.

[0037] Of course, in some other embodiments, there may be two or more separation partitions S. When there are two separation partitions S, one of them is connected to the exhaust cover 2, and the other is connected to the stationary vortex disk 41.

[0038] Please see Figure 6 and Figure 7 To further reduce processing difficulty, in some embodiments, the separation partition S and at least a portion of the exhaust cover 2 or at least a portion of the stationary vortex disk 41 are integral parts. The method of obtaining this integral part is not specifically limited; it can be obtained through one or a combination of welding, casting, powder metallurgy, metal powder injection molding, etc. Alternatively, it can be obtained by machining after welding, casting, powder metallurgy, or metal powder injection molding, or it can be obtained directly through machining. In some specific embodiments, machining is performed on both parts, allowing for identical positioning on a machine tool, ensuring positioning accuracy and reducing errors.

[0039] In some embodiments, the number of separation baffles S is not limited; some separation baffles S can be integral with the exhaust cover 2, and other separation baffles S can be integral with the stationary vortex disk 41. Figure 6In the embodiment shown, one separation baffle S is integrated with the exhaust cover 2, and the other separation baffle S is integrated with the stationary vortex disk 41.

[0040] In some embodiments, the separation partition S extends axially along the housing 1, and the separation partition S is a cylindrical body for easy processing. See also... Figure 6 and Figure 7 In some embodiments, the separation partition S extends along the axial direction of the housing 1, and a plane perpendicular to the axial direction of the housing 1 is defined as the first surface. The projection of the separation partition S onto the first surface is annular. Of course, in other embodiments, the projection of the separation partition S onto the first surface can also be other shapes, and the first cavity 110a falls into the enclosed area it forms.

[0041] Please see Figure 6 To improve the oil-gas separation effect, in some embodiments, the number of separation baffles S is at least two, including a first baffle 411 and a second baffle 21. One of the first baffle 411 and the second baffle 21 is connected to the exhaust cover 2, and the other of the first baffle 411 and the second baffle 21 is connected to the stationary vortex disk 41. The separation channel 110c is at least partially located between the first baffle 411 and the second baffle 21. Please refer to [link / reference]. Figure 6 In some embodiments, the first partition 411 and the second partition 21 are arranged radially along the stationary vortex disk 41. In this case, the first partition 411 and the second partition 21 are connected to the stationary vortex disk 41 and the exhaust cover 2, respectively. A third gap L3 is formed between the first partition 411 and the second partition 21 along the radial direction of the housing 1, which can form a separation channel 110c with a folding structure. The separation channel 110c with the folding structure can further reduce the flow velocity of the high-pressure refrigerant and lubricating oil mixture in the exhaust chamber 110 when it passes through the separation channel 110c, which is more conducive to oil-gas separation.

[0042] In some embodiments, the equivalent flow area of ​​any one of the first gap L1, the second gap L2, and the third gap L3 is greater than the equivalent flow area of ​​the exhaust inlet 121a of the exhaust passage 12a, to prevent excessive pressure drop.

[0043] Of course, in some other embodiments, the first partition 411 and the second partition 21 can also be arranged along the axial direction of the stationary vortex disk 41. In this case, there is a gap L between the first partition 411 and the second partition 21 along the axial direction of the housing 1. In some specific embodiments, the gap L is annular.

[0044] In some embodiments, the separation partition S has a cylindrical structure, which facilitates processing. Furthermore, when the number of separation partitions S is at least two, a double-layer cylindrical structure can be formed, which has a certain noise reduction effect.

[0045] Please seeFigure 6 To further improve the oil-gas separation effect, in some specific embodiments, the first partition 411 and the second partition 21 are arranged radially along the stationary vortex disk 41. The first partition 411 is connected to the stationary vortex disk 41. Along the axial direction of the stationary vortex disk 41, there is a first gap L1 between the first partition 411 and the exhaust cover 2. The second partition 21 is connected to the exhaust cover 2. Along the axial direction of the stationary vortex disk 41, there is a second gap L2 between the second partition 21 and the stationary vortex disk 41. Along the radial direction of the stationary vortex disk 41, there is a third gap L3 between the first partition 411 and the second partition 21. The first gap L1, the second gap L2, and the third gap L3 are connected. The separation channel 110c includes the first gap L1, the second gap L2, and the third gap L3, that is, the first gap L1, the second gap L2, and the third gap L3 form at least a portion of the separation channel 110c. Please refer to [link to relevant documentation]. Figure 6 In some embodiments, the first gap L1, the second gap L2, and the third gap L3 can form a separation channel 110c with a folding structure, reducing the flow velocity of the high-pressure refrigerant and lubricating oil mixture in the exhaust chamber 110 as it passes through the separation channel 110c, thus facilitating oil-gas separation. In particular, in Figure 6 In the illustrated embodiment, there is one first partition 411 and one second partition 21; of course, in other embodiments, the number of either the first partition 411 or the second partition 21 may be two or more, to form a separation channel 110c with multiple foldback structures. Figure 6 In the illustrated embodiment, the equivalent flow area of ​​the first gap L1 is greater than the equivalent flow area of ​​the second gap L2.

[0046] Please see Figure 6 and Figure 7 In some embodiments, the first partition 411 and the stationary vortex disk 41 are at least partially integral; and / or, the second partition 21 and the exhaust cover 2 are at least partially integral. In some embodiments, the first partition 411 and the stationary vortex disk 41 are integral, the second partition 21 and the exhaust cover 2 are integral, and the first partition 411 and the second partition 21 are cylindrical structures for easy processing.

[0047] In some embodiments, the first partition 411 is closer to the axis of the housing 1 than the second partition 21. With this structure, when the high-pressure refrigerant and lubricating oil mixture is ejected laterally from the volute exhaust port 410 of the stationary volute 41 along the radial direction of the stationary volute 41 into the first chamber 110a, it is first blocked by the first partition 411, and then enters the second chamber 100b through a zigzag channel formed by the first gap L1, the third gap L3, and the second gap L2. The zigzag channel can reduce the flow velocity to a certain extent, facilitating oil-gas separation. The separated oil can adhere to the outer wall of the separation partition S and the inner wall of the housing 1 where the second chamber 100b is located. The separated oil eventually drips off under gravity and is returned via the oil return structure. In some embodiments, the oil return structure is an oil return channel T, and a throttling element 5 is provided at the inlet of the oil return channel T.

[0048] In some specific embodiments, a plane perpendicular to the axial direction of the housing 1 is defined as a first surface, the projection of the first partition 411 onto the first surface is a first projection surface, the projection of the second partition 21 onto the first surface is a second projection surface, and the first projection surface is closer to the axis of the housing 1 than the second projection surface.

[0049] Please see Figure 4 and Figure 6 In some embodiments, the stationary scroll 41 has a scroll exhaust port 410, which is connected to the first chamber 110a. At least one of the exhaust cover 2 and the housing 1 has an exhaust channel 12a, which is connected to the second chamber 100b. In some embodiments, when the high-pressure refrigerant and lubricating oil mixture is ejected from the scroll exhaust port 410 of the stationary scroll 41 into the first chamber 110a, it enters the second chamber 100b through the separation channel 110c for oil-gas separation. The separated oil can adhere to the outer wall of the separation partition S and the inner wall of the housing 1 where the second chamber 100b is located in the second chamber 100b. The separated oil eventually drips off under the action of gravity and returns to the compressor through the oil return channel T to achieve oil return.

[0050] Please see Figure 6 , Figure 7 and Figure 8 In some embodiments, the compressor further includes an exhaust valve 401 and an exhaust valve limiting member 402, which are at least partially located in the first chamber 110a. The exhaust valve 401 and the exhaust valve limiting member 402 are connected to the stationary scroll 41. The exhaust valve 401 is located between the stationary scroll 41 and the exhaust valve limiting member 402. The exhaust valve 401 can block or open the scroll exhaust port 410. When the high-pressure refrigerant and lubricating oil mixture is compressed in the compression chamber between the stationary scroll 41 and the moving scroll 42 to a pressure value exceeding the set pressure value of the exhaust valve 401, the high-pressure refrigerant and lubricating oil mixture is ejected from the scroll exhaust port 410 into the first chamber 110a.

[0051] When the compressor is working, the refrigerant and lubricating oil mixture in the low-pressure chamber flows through the gap between the stator 451 and the motor housing 453 of the motor assembly 45, and then enters the compression chamber between the stationary scroll 41 and the moving scroll 42 through the second through groove 4300 on the main bearing seat 43. The compressed high-pressure refrigerant and lubricating oil mixture is ejected through the scroll exhaust port 410 into the high-pressure chamber. The low-pressure chamber is the inner cavity of the mounting cavity 10 closer to the end cover 3, and the high-pressure chamber is the inner cavity of the mounting cavity 10 closer to the exhaust cover 2, which is the exhaust chamber 110. When the high-pressure refrigerant and lubricating oil mixture is ejected through the scroll exhaust port 410 into the first chamber 110a, it is first blocked by the first partition 411, and then enters the second chamber 100b through the folding channel formed by the first gap L1, the third gap L3, and the second gap L2. The folding channel can reduce the flow rate to a certain extent, which is more conducive to oil return.

[0052] In some embodiments, a stationary scroll plate 41 and a stationary plate seal 415 are used to separate the high-pressure chamber and the low-pressure chamber of the compressor 100, reducing the risk of leakage of the mixed gas in the high-pressure chamber to the low-pressure chamber side. For details, please refer to... Figure 4 and Figure 11 The compressor 100 also includes a stationary disc seal 415, which is located between the stationary scroll 41 and the housing 1. The stationary disc seal 415 is connected to and seals with at least one of the stationary scroll 41 and the housing 1. In one specific embodiment, the inner ring side of the stationary disc seal 415 abuts and engages with the stationary scroll 41, while the outer ring side of the stationary disc seal 415 abuts and seals with the housing 1, thereby forming a seal between the stationary scroll 41 and the housing 1.

[0053] Please see Figure 7 In some embodiments, the first cavity 110a and the second cavity 100b are arranged radially along the stationary vortex disk 41, with the second cavity 100b being further away from the axis of the stationary vortex disk 41 than the first cavity 110a. In a specific embodiment, the separation partition S is a cylindrical body.

[0054] Please see Figure 6 and Figure 7 In some embodiments, the compressor 100 has an oil return channel T and an oil return chamber 120, with a second chamber 100b communicating with the oil return channel T and the oil return channel T communicating with the oil return chamber 120. The compressor 100 also includes a moving scroll 42 and a main bearing housing 43, with the oil return chamber 120 located between the main bearing housing 43 and the moving scroll 42. Please refer to [link to relevant documentation]. Figure 6When the high-pressure refrigerant and lubricating oil mixture is ejected from the scroll exhaust port 410 of the stationary scroll 41 into the first chamber 110a, it enters the second chamber 100b via the separation channel 110c for oil-gas separation. The separated oil can adhere to the outer wall of the separation partition S and the inner wall of the housing 1 where the second chamber 100b is located. The separated oil eventually drips off under the action of gravity and returns to the return oil chamber 120 via the return oil channel T. In some embodiments, the compressor 100 includes a compressor core assembly 4, which includes a stationary scroll 41, a moving scroll 42, a main bearing housing 43, a main bearing 430, and a drive bearing 440. The oil entering the return oil chamber 120 can lubricate the main bearing 430 and the drive bearing 440 of the compressor core assembly 4, and can also lubricate the space between the stationary scroll 41 and the moving scroll 42.

[0055] In some other embodiments, the compressor core assembly 4 further includes a drive shaft assembly 44, a motor assembly 45, and a first connector 46. The motor assembly 45 includes a motor housing 453, and the motor housing 453, main bearing seat 43, and stationary scroll 41 are arranged along the axial direction of the compressor core assembly 4. The first connector 46 is connected to the motor housing 453, main bearing seat 43, and stationary scroll 41. The components of the compressor core assembly 4 can be pre-assembled, and then the pre-assembled parts of the compressor core assembly 4 are assembled with the housing 1. Finally, the exhaust cover 2, end cover 3, and housing 1 are sealed by welding, which can reduce the number of leakage points in the compressor.

[0056] In some embodiments, the compressor core assembly 4 of the compressor 100 further includes a throttling element 5, which is connected to the oil return channel T. The separated oil is throttled by the throttling element 5 before entering the oil return chamber 120. During operation, the compressor is arranged in the following manner: Figure 6 As shown in the diagram, the throttling element 5 and the return oil flow channel T are positioned at a lower level in the direction of gravity, which facilitates oil return. In a specific embodiment, the inlet 51 of the throttling element 5 is at least partially located in the second cavity 100b, meaning that the inlet 510 of the inlet 51 is exposed in the second cavity 100b, reducing the risk of blockage. During oil return, the oil can more smoothly enter the throttling channel P of the throttling element 5 through the inlet 510 located in the exhaust cavity 110, and then enter the return oil flow channel T from the outlet 520 of the throttling element 5, reducing the risk of oil return blockage.

[0057] Please see Figure 6 and Figure 7In some embodiments, the compressor 100 further includes a limiting part 22, one end of which is connected to one of the stationary scroll 41 and the exhaust cover 2, and the other end of which is in contact with the other of the stationary scroll 41 and the exhaust cover 2. The limiting part 22 extends axially along the housing 1, and the limiting part 22 is at least partially integral with one of the stationary scroll 41 and the exhaust cover 2. In some specific embodiments, the limiting part 22 is connected to the exhaust cover 2, and the limiting part 22 and the exhaust cover 2 are at least partially integral, which facilitates processing. The method of obtaining the integral part is not specifically limited; it can be obtained through one or a combination of welding, casting, powder metallurgy, metal powder injection molding, etc., or it can be obtained by machining after welding, casting, powder metallurgy, or metal powder injection molding, or it can be obtained directly by machining. In some specific embodiments, machining is performed on both parts, so that the same positioning process can be used on the machine tool, ensuring the positioning accuracy of both parts and reducing errors. The limiting part 22 is further away from the axis of the housing 1 than the separating partition part S. The limiting part 22 facilitates the installation and positioning of the exhaust cover 2.

[0058] Please see Figure 4 and Figure 6 In some embodiments, the compressor 100 further includes a compressor core assembly 4 and an end cover 3. The compressor core assembly 4 includes a stationary scroll 41, and the end cover 3 is connected to the housing 1. The exhaust cover 2, the compressor core assembly 4, and the end cover 3 are arranged along the axial direction of the housing 1. At least one of the exhaust cover 2 and the end cover 3 is welded to the housing 1. In some embodiments, assembling the compressor core assembly 4 with the housing 1 and then welding the exhaust cover 2 and the end cover 3 to the housing 1 can reduce the number of leakage points of the compressor. Compared with the pipeline connection method, the welding method of the exhaust cover 2 and the end cover 3 has a lower risk of leakage.

[0059] Compressors in related technologies generally employ a split-shell structure, requiring gaskets to seal the core components used for refrigerant compression. Removing these gaskets can easily lead to leaks at the shell joints. However, gaskets have a limited compression range, making dimensional chain control difficult. In some specific embodiments, the shell 1 in this application uses a one-piece structure and is welded to the exhaust cap 2 and end cap 3 to reduce leakage points. This allows the compressor core assembly 4, used for refrigerant compression, to reduce the use of gaskets between parts, thereby simplifying dimensional chain calculations.

[0060] The housing 1 is a single piece, and the method of obtaining this single piece is not specifically limited. It can be obtained through one or a combination of welding, casting, powder metallurgy, metal powder injection molding, deep drawing, etc., or it can be obtained by welding, casting, powder metallurgy, or metal powder injection molding followed by machining, or it can be obtained directly by machining. In some specific embodiments, the housing 1 can be produced using a deep drawing process, which can reduce mold opening and processing costs. In other embodiments, the housing 1 can also be an extruded part, with the length direction of the mounting cavity 10 aligned with the length direction of the housing 1, which can reduce processing difficulty.

[0061] In some embodiments, the end cap 3 includes a flange 31 located at one end of the end cap 3 facing the exhaust cover 2. The housing 1 has a stepped limiting groove 13, with the flange 31 at least partially located in the stepped limiting groove 13, which facilitates the limiting of the end cap 3. In some embodiments, the compressor 100 also includes a three-phase terminal 30 electrically connected to the motor assembly 45, which is mounted on the end cap 3.

[0062] To reduce the phenomenon of oil not being able to smoothly enter the throttling element due to impurities clogging it, in some embodiments, this application also provides a compressor. Please refer to [link to relevant documentation]. Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 11 The compressor 100 includes an exhaust cover 2, a stationary scroll 41, a main bearing housing 43, and a throttling element 5. The compressor 100 has an exhaust chamber 110 located between the exhaust cover 2 and the stationary scroll 41. The throttling element 5 is connected to at least one of the stationary scroll 41 and the main bearing housing 43. The throttling element 5 includes an inlet portion 51 and an outlet portion 52 connected together. The inlet portion 51 is at least partially located in the exhaust chamber 110, and the exhaust chamber 110 communicates with the inlet 510. The throttling element 5 has a throttling channel P, with the inlet 510 communicating with the throttling channel P. The outlet portion 52 has an outlet 520, with the throttling channel P communicating with the outlet 520. During oil return, the oil can more smoothly enter the throttling channel P of the throttling element 5 through the inlet 510 externally located in the exhaust chamber 110, reducing the phenomenon of oil not being able to smoothly enter the throttling element due to impurities clogging it.

[0063] Please see Figure 12 and Figure 13In some embodiments, a filtration structure is employed to further reduce the risk of impurities clogging the oil during return. Specifically, the inlet 51 includes a filter 511, which is at least partially located in the exhaust chamber 110. The filter 511 has an inlet 510, at least one of which is located in the exhaust chamber 110. The filter 511 has a filter chamber 500, and the inlet 510 communicates with the filter chamber 500. The throttling channel P includes a throttling inlet P1, and the filter chamber 500 communicates with the throttling inlet P1. Please refer to [link to relevant documentation]. Figure 6 , Figure 12 and Figure 13 During oil return, the oil at the bottom of the exhaust chamber 110 first enters the filter chamber 500 through the inlet 510, and then enters the throttling channel P through the throttling inlet P1. On the one hand, the filtration effect of the filter section 511 can reduce the entry of impurities, and the inlet 510 is located in the exhaust chamber 110, which can reduce the adhesion of impurities under the flushing of the refrigerant and oil mixture. On the other hand, the addition of the filter section 511 can also slow down the flow speed of the oil, achieving a throttling effect. In some embodiments, the axial direction of the inlet 510 does not coincide with the axial direction of the throttling channel P, which can reverse the path of the oil entering the filter chamber 500, further slowing down the flow speed of the oil and improving the throttling effect.

[0064] Please see Figure 12 and Figure 13 In some specific embodiments, the filter section 511 includes an end wall section 511a and a peripheral wall section 511b. The end wall section 511a is connected to the peripheral wall section 511b, and the end wall section 511a is located at the end of the peripheral wall section 511b facing away from the outlet 520. There are at least two inlets 510, which are arranged circumferentially on the peripheral wall section 511b. See also... Figure 12 and Figure 13 In some embodiments, a plurality of inlets 510 are evenly arranged circumferentially on the peripheral wall portion 511b, which can form filter holes in the filter portion 511 to achieve the effect of filtering impurities in the lubricating oil, further reducing the risk of the throttling element 5 being blocked by impurities. In some specific embodiments, the filter holes can be evenly arranged in the exhaust chamber 110.

[0065] Please see Figure 12 and Figure 13 In some embodiments, the axis of at least one inlet 510 does not coincide with the axis of the throttling channel P. When the oil enters the filter chamber 500 from the inlet 510, the oil's path is reversed before entering the throttling channel P, thereby slowing down the oil flow speed to a certain extent and improving the throttling effect.

[0066] In some specific embodiments, the axial direction of the peripheral wall portion 511b is consistent with the axial direction of the throttling channel P, and the inlet 510 is arranged in the peripheral wall portion 511b such that the axial direction of the inlet 510 does not coincide with the axial direction of the throttling channel P. Of course, in other embodiments, the inlet 510 can also be provided in the end wall portion 511a to form the filter hole of the filter portion 511.

[0067] Please see Figure 12 and Figure 13 In some embodiments, the throttling channel P is at least partially located in the outlet portion 52. The outlet portion 52 includes a first throttling portion 521 having a throttling inlet P1. The filter chamber 500 communicates with the throttling inlet P1, and the throttling inlet P1 communicates with the throttling channel P. The outlet portion 52 also includes a second throttling portion 522, connected to the first throttling portion 521. The second throttling portion 522 has an outlet 520. The compressor 100 also has an oil return passage T, with the outlet 520 communicating with the oil return passage T. The first throttling portion 521 is at least partially located in the filter chamber 500, and / or the second throttling portion 522 is at least partially located in the oil return passage T. In some embodiments, the first throttling portion 521 and the second throttling portion 522 extend axially along the outlet portion 52, and the throttling channel P extends axially along the outlet portion 52. The length direction of the outlet portion 52 is consistent with the length direction of the inlet portion 51. In some embodiments, the first throttling section 521 is located within the area enclosed by the end wall section 511a where the inlet 510 is located, causing the oil's travel path to be reversed before entering the throttling channel P, thereby slowing down the oil flow speed to a certain extent and improving the throttling effect.

[0068] Please see Figure 6 In some embodiments, the exhaust chamber 110 includes a first chamber 110a and a second chamber 100b, the first chamber 110a and the second chamber 100b are arranged radially along the exhaust chamber 110, the second chamber 100b is further away from the axis of the exhaust chamber 110 than the first chamber 110a, the inlet portion 51 is at least partially located in the second chamber 100b, and the second chamber 100b communicates with the inlet 510; the compressor 100 includes a separation partition S, the separation partition S is at least partially located between the first chamber 110a and the second chamber 100b, the compressor 100 has a separation channel 110c, the first chamber 110a communicates with the separation channel 110c, and the separation channel 110c communicates with the second chamber 100b.

[0069] Please see Figure 6To further improve the oil-gas separation effect, in some embodiments, the separation baffle S is at least two, including a first baffle 411 and a second baffle 21. The first baffle 411 and the second baffle 21 are arranged radially along the stationary vortex disk 41. The first baffle 411 is connected to the stationary vortex disk 41. Along the axial direction of the stationary vortex disk 41, the first baffle 411 and the exhaust cover 2 have a first gap L1. The second baffle 21 is connected to the exhaust cover 2.

Along the radial direction of the stationary vortex disk 41, the first baffle 411 and the second baffle 21 have a third gap L3. The first gap L1, the second gap L2, and the third gap L3 are connected and form at least a portion of the separation channel 110c. Please refer to [link to relevant documentation]. Figure 6 In some embodiments, the first gap L1, the second gap L2 and the third gap L3 can form a separation channel 110c with a folding structure. The high-pressure refrigerant and lubricating oil mixture in the exhaust chamber 110 has its flow rate reduced by passing through the separation channel 110c, which is beneficial for oil-gas separation.

[0070] Please see Figure 6 and Figure 11 In some embodiments, at least one of the inlet portion 51 and the outlet portion 52 is connected to at least one of the stationary scroll plate 41 and the main bearing housing 43.

Of course, in other embodiments, at least one of the inlet portion 51 and the outlet portion 52 may also be connected to the main bearing housing 43, which has the first mounting groove 412; or, the stationary scroll plate 41 and the main bearing housing 43 may each have a corresponding first mounting groove 412.

[0071] Please see Figure 11 In some embodiments, the stationary vortex disk 41 includes a second limiting surface 412a located in the first mounting groove 412, and the outlet portion 52 includes a limiting stepped surface 52a in contact with the second limiting surface 412a. The second limiting surface 412a can axially limit the throttling element 5, facilitating the limiting installation of the throttling element 5.

[0072] Please see Figure 11 to Figure 13In some embodiments, the compressor 100 further includes a seal 54 located between at least one of the stationary scroll plate 41 and the main bearing housing 43 and the throttling element 5. Multiple seals 54 may be present, and each seal 54 may be fitted over the outside of at least one of the inlet portion 51 and the outlet portion 52. In this embodiment, by equipping the throttling element 5 with a seal 54, the risk of pressure leakage from the high-pressure chamber to the low-pressure chamber due to unreliable sealing can be reduced, allowing the working medium and oil to enter the throttling channel P as much as possible.

[0073] Please see Figure 11 to Figure 13 In some embodiments, one of the inlet portion 51 and the outlet portion 52 includes a connecting portion 53, and the other of the inlet portion 51 and the outlet portion 52 is connected to the connecting portion 53. A seal 54 is located between at least one of the stationary volute 41 and the main bearing housing 43 and the connecting portion 53. In some specific embodiments, the seal 54 is an O-ring. In some embodiments, one of the inlet portion 51 and the outlet portion 52 is integral with the connecting portion 53, and the other is assembled and connected to the connecting portion 53. Alternatively, both the inlet portion 51 and the outlet portion 52 can be welded to the connecting portion 53.

[0074] In some embodiments, at least one of the connecting portion 53, the stationary scroll plate 41, and the main bearing housing 43 has a sealing groove 531, and the seal 54 is at least partially located in the sealing groove 531. In some specific embodiments, the seal 54 is arranged between the connecting portion 53 and the stationary scroll plate 41 and abuts against both, improving the reliability of the seal. Specifically, the connecting portion 53 has a sealing groove 531, the inner ring side of the seal 54 abuts against the wall forming the sealing groove 531 for sealing, and the outer ring side of the seal 54 abuts against the wall forming the first mounting groove 412 for sealing.

[0075] Please see Figure 6 and Figure 11In some embodiments, the compressor 100 further includes a moving scroll 42, and the compressor 100 has an oil return chamber 120 located between the main bearing housing 43 and the moving scroll 42. The compressor 100 has an oil return channel T, which is at least partially located in the main bearing housing 43 and communicates with the oil return chamber 120.

The oil return chamber 120 is located between the main bearing 430 and the drive bearing 440. The oil that enters the oil return chamber 120 through the oil return channel T can lubricate the main bearing 430 and the drive bearing 440. On the other hand, it can also enter the low-pressure chamber inside the compressor through the main bearing 430 and then enter the compression chamber between the stationary scroll 41 and the moving scroll 42 for lubrication.

[0076] Please see Figure 6 and Figure 11 In some embodiments, the return oil flow channel T includes a first return oil flow channel T1 and a second return oil flow channel T2. One end of the first return oil flow channel T1 is connected to the throttling channel P, and the other end of the first return oil flow channel T1 is connected to the second return oil flow channel T2. The second return oil flow channel T2 is connected to the return oil chamber 120, and the axis of the first return oil flow channel T1 intersects the axis of the second return oil flow channel T2. Using two intersecting return oil flow paths can bend the oil's path, further slowing down the oil flow speed and achieving a throttling effect. In some embodiments, the angle between the axis of the first return oil flow channel T1 and the axis of the second return oil flow channel T2 is an acute angle; however, in other embodiments, the angle can also be a right angle or an obtuse angle.

[0077] To improve the stator's shaft centering accuracy, in some embodiments, this application also provides a compressor; please refer to [link to relevant documentation]. Figure 1 , Figure 2 , Figure 4 , Figure 8 to Figure 11 The compressor includes a housing 1 and a compressor core assembly 4, which is connected to the housing 1. The housing 1 has a mounting cavity 10, and the compressor core assembly 4 is at least partially located in the mounting cavity 10. The compressor core assembly 4 includes a main bearing housing 43 and a motor assembly 45. The motor assembly 45 includes a stator 451, a rotor 452, and a motor housing 453. The motor housing 453 has a stator mounting cavity 450, and the stator 451 is at least partially located in the stator mounting cavity 450. The stator 451 is connected to the motor housing 453, and the motor housing 453 is connected to the main bearing housing 43. Positioning the stator 451 using the stator mounting cavity 450 improves the axial positioning accuracy of the stator.

[0078] Please see Figure 4 , Figure 14 and Figure 15 In some embodiments, the motor housing 453 includes a first protruding positioning portion 4531, which extends from the inner wall of the motor housing 453 toward the axis of the motor housing 453; the first protruding positioning portion 4531 includes a first connecting arc surface 4531c, which is located on the side of the first protruding positioning portion 4531 toward the axis of the motor housing 453, and the first connecting arc surface 4531c contacts the outer peripheral wall of the stator 451.

[0079] In some embodiments, the first protruding positioning part 4531 is interference-fitted to the stator 451 via a first connecting arc surface 4531c, and the inner wall of the motor housing 453 has an inwardly convex first protruding positioning part 4531 to facilitate the assembly of the stator 451 and the motor housing 453. Of course, in other embodiments, the two can also be connected in other ways, such as welding, assembly, etc.

[0080] In some embodiments, the motor housing 453 and the first protruding positioning part 4531 are integral parts. The method of obtaining this integral part is not specifically limited; it can be obtained through one or a combination of welding, casting, powder metallurgy, metal powder injection molding, etc. Alternatively, it can be obtained by welding, casting, powder metallurgy, or metal powder injection molding followed by machining, or it can be directly machined. In some specific embodiments, both are machined to ensure positioning accuracy and reduce errors through identical positioning processes on a machine tool.

[0081] Please see Figure 14 In some embodiments, a plane perpendicular to the axial direction of the motor housing 453 is defined as the first projection plane, and the projection of the first connecting arc surface 4531c on the first projection plane is an arc. Within the allowable range of processing errors, the circles of the arcs projected by each first connecting arc surface 4531c roughly coincide to adapt to the outer peripheral wall contour of the stator 451.

[0082] Please see Figure 14 and Figure 16a and Figure 16bIn some embodiments, there are at least two first protruding positioning portions 4531, which are arranged circumferentially at intervals. The motor housing 453 has a first through groove 4530 located between adjacent first protruding positioning portions 4531. Refrigerant entering the mounting cavity 10 through the intake channel 12b can enter the compression cavity through the first through groove 4530 of the motor housing 453 and the second through groove 4300 on the main bearing seat 43. In addition, the stator 451 has some protruding parts on its outer periphery, such as busbars and wires. The first through groove 4530 between the first protruding positioning portions 4531 can not only reduce weight but also provide space for the busbars.

[0083] Please see Figure 14 and Figure 16a and Figure 16b In some embodiments, the motor housing 453 further includes a limiting step portion 4531a, which extends from the inner wall of the first protruding positioning portion 4531 toward the axis of the motor housing 453, and the end of the stator 451 contacts the limiting step portion 4531a. The limiting step portion 4531a can axially limit the stator 451. In some embodiments, the limiting step portion 4531a is located at one end of the length direction of the first protruding positioning portion 4531, which can reserve more installation space for the stator 451 inside the motor housing 453. The length direction of the first protruding positioning portion 4531 is the same as the axial direction of the motor housing 453, and the first protruding positioning portion 4531 can have a longer dimension, improving the positioning accuracy of the stator 451 and the first protruding positioning portion 4531, as well as the reliability of their interference fit. In one specific embodiment, the motor housing 453 includes a bearing seat portion 4533, which is located at one end of the motor housing 453 facing away from the moving scroll 42. A limiting step portion 4531a is located at one end of the first protruding positioning portion 4531 facing the bearing seat portion 4533. The limiting step portion 4531a contacts one end of the stator 451 and can axially limit the stator 451.

[0084] In some embodiments, the first protrusion positioning part 4531 further includes a first guide slope 4531b, which is located at the other end of the length direction of the first protrusion positioning part 4531. The guiding function of the first guide slope 4531b facilitates the assembly of the stator 451 and the motor housing 453.

[0085] Please see Figure 14In some embodiments, the motor housing 453 further includes a second protruding positioning portion 4532, which extends from the outer wall of the motor housing 453 away from the axis of the motor housing 453. The second protruding positioning portion 4532 includes a second connecting arc surface 4532b, which is located on the side of the second protruding positioning portion 4532 away from the axis of the motor housing 453 and contacts the inner peripheral wall of the housing 1. There are at least two second protruding positioning portions 4532, which are arranged circumferentially spaced. In some embodiments, the second protruding positioning portion 4532 is interference-fitted to the housing 1 through the second connecting arc surface 4532b. The protruding second protruding positioning portion 4532 on the outer wall of the motor housing 453 facilitates the assembly of the motor housing 453 and the housing 1. Of course, in other embodiments, the two can also be connected in other ways, such as welding, assembly, etc. In some embodiments, at least one end of the second protruding positioning portion 4532 includes a second guide slope 4532a, which has a guiding function to facilitate the assembly of the motor housing 453 and the housing 1. In a specific embodiment, the second guide slope 4532a is located at both ends of the second protruding positioning portion 4532.

[0086] Please see Figure 4 In some embodiments, the motor housing 453 is connected to the housing 1. The housing 1 includes a first limiting surface 14 located in the mounting cavity 10, and one end of the motor housing 453 contacts the first limiting surface 14. The first limiting surface 14 is used to axially limit the motor housing 453, facilitating the limited installation of the motor housing 453 and the housing 1. In some specific embodiments, the motor housing 453 is connected to the housing 1 using an interference fit. Of course, in other embodiments, the two can also be assembled and connected using bolts.

[0087] Please see Figure 17 , Figure 18 and Figure 19 In some embodiments, the mounting cavity 10 includes a stationary disk mounting cavity 10a and a motor mounting cavity 10b. The compressor core assembly 4 also includes a stationary scroll 41 connected to the main bearing housing 43. The stationary scroll 41 is at least partially located in the stationary disk mounting cavity 10a. The motor assembly 45 is at least partially located in the motor mounting cavity 10b, and the motor assembly 45 is interference-fitted with the housing 1 at the motor mounting cavity 10b. In some specific embodiments, the inner diameter of the motor mounting cavity 10b is smaller than the inner diameter of the stationary disk mounting cavity 10a. When assembling the compressor core assembly 4 into the housing 1, the larger inner diameter of the stationary disk mounting cavity 10a facilitates smoother assembly of the compressor core assembly 4.

[0088] Please see Figure 4In some embodiments, the compressor core assembly 4 further includes a stationary scroll 41 and a first connecting member 46. The motor housing 453, the main bearing seat 43, and the stationary scroll 41 are arranged along the axial direction of the compressor core assembly 4, and the first connecting member 46 is connected to the motor housing 453, the main bearing seat 43, and the stationary scroll 41. In some embodiments, the compressor core assembly 4 is pre-assembled first, then the compressor core assembly 4 is interference-fitted to the housing 1, and finally the exhaust cover 2 and the end cover 3 are welded to the housing 1, which can reduce the leakage points of the compressor.

[0089] In some embodiments, multiple spaced-apart first connectors 46 connect the motor housing 453, the main bearing seat 43, and the stationary scroll 41, and the same first connector 46 can connect all three simultaneously. See also... Figure 9 The motor housing 453, the main bearing seat 43, and the stationary volute 41 each have mounting holes 460 for mating with the first connecting member 46.

[0090] Please see Figure 9 , Figure 14 and Figure 16a and Figure 16b In some embodiments, the compressor core assembly 4 further includes a first positioning pin 48, wherein one end of the first positioning pin 48 is located in the first pin hole 4534 of the motor housing 453, and the other end of the first positioning pin 48 is located in the second pin hole 4301 of the main bearing seat 43. The first positioning pin 48 can be used to position the motor housing 453 and the main bearing seat 43, so that the first connecting member 46 can connect the motor housing 453, the main bearing seat 43 and the stationary scroll 41.

[0091] In some embodiments, the compressor core assembly 4 further includes a second positioning pin 49, wherein one end of the second positioning pin 49 is located in the third pin hole of the stationary scroll 41, and the other end of the second positioning pin 49 is located in the second pin hole 4301 of the main bearing housing 43. The second positioning pin 49 can be used to limit the stationary scroll 41 and the main bearing housing 43, so that the first connecting member 46 can connect the motor housing 453, the main bearing housing 43 and the stationary scroll 41.

[0092] In some embodiments, the second pin hole 4301 extends through the main bearing housing 43 along its length, and the pin holes at both ends of the main bearing housing 43 coincide, such that the first locating pin 48 and the second locating pin 49 are arranged axially along the second pin hole 4301. Of course, in other embodiments, the two ends of the main bearing housing 43 may also use staggered pin holes, which are used for the mating installation of the first locating pin 48 and the second locating pin 49, respectively.

[0093] Please see Figure 4In some embodiments, the compressor 100 further includes an exhaust cover 2 and an end cover 3, both of which are connected to the housing 1. The exhaust cover 2, the compressor core assembly 4, and the end cover 3 are arranged along the axial direction of the housing 1. At least one of the exhaust cover 2 and the end cover 3 is welded to the housing 1. In some embodiments, assembling the compressor core assembly 4 with the housing 1 and then welding the exhaust cover 2 and the end cover 3 to the housing 1 can reduce the number of leakage points of the compressor. Compared with the method of using pipeline connection, the risk of leakage is lower when the exhaust cover 2 and the end cover 3 are welded.

[0094] The compressor 100 has an exhaust passage 12a and an intake passage 12b, at least one of which is located in the housing 1. In some embodiments, the housing 1 is an integrally extruded part, and both the exhaust passage 12a and the intake passage 12b are arranged in the housing 1.

[0095] Please see Figure 6 , Figure 11 , Figure 18 and Figure 19 In some embodiments, the housing 1 has a stationary disk mounting cavity 10a, and a stationary volute 41 is at least partially located in the stationary disk mounting cavity 10a. The stationary volute 41 includes a fixed disk portion 41a and a stationary disk seal 415. The stationary disk seal 415 is connected to the fixed disk portion 41a and is at least partially located in the mounting gap between the fixed disk portion 41a and the housing 1, and is sealed to the fixed disk portion 41a and the housing 1. The housing 1 has a cavity W and an exhaust channel 12a. The cavity W includes a clearance cavity W10, the inner diameter of which is larger than the inner diameter of the stationary disk mounting cavity 10a. The exhaust channel 12a has an exhaust inlet 121a. The housing 1 includes a groove wall surface W1, and the wall forming the clearance cavity W10 includes the groove wall surface W1. The exhaust inlet 121a is at least partially located on the groove wall surface W1. When installing the stationary volute, the risk of the stationary volute seal 415 scraping against the exhaust inlet 121a at the clearance cavity W10 can be reduced to a certain extent, thereby reducing the risk of mixed gas in the high-pressure cavity leaking to the low-pressure cavity side. The exhaust passage 12a also has an exhaust outlet 122a, which is located on the outer wall side of the housing 1, and the exhaust inlet 121a is connected to the exhaust outlet 122a.

[0096] In some embodiments, when the stationary scroll plate 41 is not installed in the stationary plate mounting cavity 10a, the outer diameter of the stationary plate seal 415 disposed on its outer periphery is defined as Z. In some embodiments, the inner diameter of the clearance cavity W10 is larger than the outer diameter Z of the stationary plate seal 415, which can further reduce the risk of the stationary plate seal 415 scraping against the exhaust inlet 121a when the stationary scroll plate 41 is installed.

[0097] Please see Figure 18 and Figure 19At least one side of the recessed cavity W is provided with a chamfered structure. Specifically, in some embodiments, the recessed cavity W includes a first guide cavity W20, and the wall forming the first guide cavity W20 includes a first inclined wall surface W2, which is located on the side of the groove wall surface W1 near the stationary scroll plate 41. Along the axial direction of the housing 1, the inner diameter of the first guide cavity W20 gradually decreases from the side away from the stationary scroll plate 41 to the side near the stationary scroll plate 41. During the installation of the stationary scroll plate 41, the first inclined wall surface W2 has a guiding function and can mitigate the sudden change in the inner diameter of the housing 1, thereby reducing the risk of damage to the stationary scroll seal 415 caused by the sudden change in the inner diameter of the housing 1. In some embodiments, the first guide cavity W20 is located between the clearance cavity W10 and the stationary scroll mounting cavity 10a. The taper of the first inclined wall surface W2 can be 15°-20°, which can better mitigate the sudden change in the inner diameter of the cavity and facilitate the installation of the stationary scroll seal 415.

[0098] Please see Figure 19 In some embodiments, the housing 1 includes a housing end face 19 located at the end of the housing 1 facing the exhaust cover 2, and a clearance cavity W10 located on the side of the stationary disk mounting cavity 10a facing the exhaust cover 2. The end of the clearance cavity W10 away from the stationary scroll 41 penetrates through the housing end face 19. The clearance cavity W10 with an end-through structure allows the end of the housing 1 to have a larger inner diameter, facilitating the smooth installation of the stationary scroll 41 into the stationary disk mounting cavity 10a.

[0099] In some embodiments, the housing 1 further includes a transition wall W4 located at both ends of the first guide cavity W20 along its axial direction. The transition wall W4 can mitigate the abrupt change in inner diameter at the connection between the first inclined wall W2 and the housing walls on both sides, reducing the risk of damage to the stationary disk seal 415 caused by the abrupt change in the inner diameter of the housing 1's inner cavity. Along the axial direction of the housing 1, the inner diameter of the cavity enclosed by the transition wall W4 gradually decreases from the side away from the stationary scroll 41 to the side closer to the stationary scroll 41.

[0100] Please see Figure 18In some embodiments, chamfered structures are provided on both sides of the concave cavity W. Specifically, the concave cavity W also includes a second guide cavity W30. The wall forming the second guide cavity W30 includes a second inclined wall surface W3, which is located on the side of the groove wall surface W1 away from the stationary volute 41. Along the axial direction of the housing 1, the inner diameter of the second guide cavity W30 gradually decreases from the side near the stationary volute 41 to the side away from the stationary volute 41. The second guide cavity W30 is located on the side of the clearance cavity W10 away from the stationary volute 41. The second inclined wall surface W3 can also mitigate the abrupt change in the inner diameter of the housing 1, thereby reducing the risk of damage to the stationary volute seal 415 caused by the abrupt change in the inner diameter of the housing 1. The taper of at least one of the first inclined wall surface W2 and the second inclined wall surface W3 can be 15°-20°, which can better mitigate the abrupt change in the inner diameter of the cavity and facilitate the installation of the stationary volute seal 415.

[0101] In some embodiments, a chamfered edge is used to reduce scratch damage to the stationary disk seal 415 caused by abrupt changes in the inner diameter at the corner of the inner wall of the housing 1. Specifically, transition walls W4 are provided at both ends of the first guide cavity W20 to mitigate the abrupt change in inner diameter at the junction of the first inclined wall W2 and the housing walls on both sides. Along the axial direction of the housing 1, the inner diameter of the cavity enclosed by the transition walls W4 gradually decreases from the side away from the stationary volute 41 to the side closer to the stationary volute 41. Similarly, transition walls W4 are provided at both ends of the second guide cavity W30 to mitigate the abrupt change in inner diameter at the junction of the second inclined wall W3 and the housing walls on both sides. Along the axial direction of the housing 1, the inner diameter of the cavity enclosed by the transition walls W4 gradually increases from the side away from the stationary volute 41 to the side closer to the stationary volute 41. In one specific embodiment, the transition walls W4 may be chamfered to create a smoother transition at the corners of the housing walls.

[0102] In some embodiments, along the axial direction of the housing 1, the width of the groove wall surface W1 is greater than or equal to the diameter of the exhaust inlet 121a, and the exhaust inlet 121a is at least partially located on the groove wall surface W1. In some embodiments, the exhaust inlet 121a is entirely located on the groove wall surface W1, such as... Figure 18 , 19 As shown, avoiding the stationary disc seal 415 is more effective. Of course, in some other embodiments, the exhaust inlet 121a may also be partially located on the groove wall surface W1 and partially located on at least one of the first inclined wall surface W2 and the second inclined wall surface W3, which can also avoid the stationary disc seal 415 to a certain extent.

[0103] In one specific embodiment, within the allowable error range, the cross section of the clearance cavity W10 perpendicular to its axis is circular, and the inner diameter of the clearance cavity W10 remains unchanged along the axial direction. The exhaust inlet 121a is located on the groove wall surface W1.

[0104] Please seeFigure 4 and Figure 9 In some embodiments, the compressor core assembly 4 further includes a moving scroll 42 and a drive shaft assembly 44, the moving scroll 42 and the drive shaft assembly 44 being driven together, and the drive shaft assembly 44 being connected to the rotor 452; the compressor 100 further includes a main bearing 430, a secondary bearing 454 and a drive bearing 440, the main bearing 430 being at least partially located between the drive shaft assembly 44 and the main bearing housing 43, the motor housing 453 including a bearing housing portion 4533, the bearing housing portion 4533 being located at one end of the motor housing 453 facing away from the moving scroll 42, the secondary bearing 454 being at least partially located between the drive shaft assembly 44 and the bearing housing portion 4533, and the drive bearing 440 being at least partially located between the moving scroll 42 and the drive shaft assembly 44. In some embodiments, a plurality of support ribs 4533a are arranged circumferentially on the bearing housing portion 4533. Within the allowable range of machining errors, the axis of the bearing housing portion 4533 coincides with the axis of the motor housing 453. The motor housing 453, stator 451, and rotor 452 are arranged in a direction perpendicular to the axis of the motor assembly 45. The compressor 100 also includes a gasket 47, which is arranged between the moving scroll 42 and the main bearing housing 43 to improve wear resistance.

[0105] In some embodiments, when the compressor 100 is working, after the stator 451 is energized, the rotor 452 can drive the drive shaft assembly 44 to rotate synchronously. Under the constraint of the anti-rotation mechanism 400, the moving scroll 42 is driven by the drive shaft assembly 44 to perform eccentric rotary translation. It does not rotate on its own axis, but only revolves around the sun. As the moving scroll 42 moves, the gas in the crescent-shaped outer ring chamber formed by the moving scroll 42 and the stationary scroll 41 is continuously pushed towards the center, the volume continuously shrinks, the pressure gradually increases, and the compression operation begins.

[0106] Please see Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 20This application also proposes a thermal management integrated device. In some embodiments, the thermal management integrated device includes a compressor as described in any one or more of the above embodiments to reduce the assembly difficulty of the separation partition. Specifically, the thermal management integrated device includes a compressor 100, which includes a housing 1, an exhaust cover 2, and a stationary scroll 41. The housing 1 has a mounting cavity 10, and the stationary scroll 41 is at least partially located in the mounting cavity 10. The exhaust cover 2 is connected to the housing 1. The compressor 100 has an exhaust chamber 110, which is located between the exhaust cover 2 and the stationary scroll 41. The exhaust chamber 110 includes a first chamber 110a and a second chamber 100b. The compressor 100 includes a separation partition S, which is connected to the housing 1. A small portion is located between the first chamber 110a and the second chamber 100b. One end of the separation partition S is connected to one of the exhaust cover 2 and the stationary scroll plate 41, and the other end of the separation partition S has a gap L between it and the other of the exhaust cover 2 and the stationary scroll plate 41. The compressor 100 has a separation channel 110c, which communicates with the first chamber 110a and the second chamber 100b. The separation channel 110c includes the gap L, which can reduce the assembly difficulty of the separation partition S of the compressor 100. Please refer to [link to relevant documentation].

In some embodiments, the flow channel plate 6 and the housing 1 can be a single piece, manufactured by casting, forging, stamping, extrusion, metal injection molding, metal powder metallurgy, etc. The flow channel plate 6 and the housing 1 can also be assembled together. In some specific embodiments, the flow channel plate 6 and the housing 1 can be extruded simultaneously, in which case the length direction of the flow channel plate 6 and the housing 1 is consistent, which can reduce processing and assembly requirements, thereby reducing processing difficulty. Of course, the flow channel plate 6 and the housing 1 can also be extruded separately and then welded together to form a single piece. In other embodiments, the flow channel plate 6 and the housing 1 can also be extruded separately and then directly assembled, or assembled together using other components.

[0108] Please see Figure 3 and Figure 5In some embodiments, the housing 1 includes an outer shell 11 and a mounting body 12. The mounting body 12 has a mounting surface 121, which is planar in some embodiments to facilitate the assembly or welding connection between the housing 1 and the flow channel plate 6. In this case, both the exhaust passage 12a and the intake passage 12b of the compressor 100 are located in the mounting body 12, serving as inlet and outlet ports connecting the compressor 100 and the flow channel plate 6, thus reducing the use of piping.
