Description

Technical Field

[0001] This utility model relates to the field of compressor equipment technology, and more specifically, to a compressor and refrigeration equipment. Background Technology

[0002] Currently, in related technologies, the separator assembly of a scroll compressor includes a separator plate and wear-resistant plates, with the wear-resistant plates forming a seal with the upper surface of the float plate. However, during compressor assembly, the flatness and parallelism of the wear-resistant plates after riveting are poor. Furthermore, thermal deformation occurs during the circumferential welding of the separator plate, and under high pressure differential conditions, the wear-resistant plates are prone to deformation, leading to poor sealing between high and low pressure. This can easily cause leakage of high-pressure refrigerant, affecting the compressor's capacity and energy efficiency. Utility Model Content

[0003] The embodiments of this utility model are intended to solve at least one of the technical problems existing in the prior art.

[0004] Therefore, a first aspect of the embodiments of this utility model provides a compressor.

[0005] A second aspect of the present invention provides a refrigeration device.

[0006] In view of the above, according to a first aspect of the present invention, a compressor is provided, the compressor comprising: a partition plate; a compression assembly including a floating groove and a compression chamber; a sealing block disposed on the partition plate, the sealing block including a sealing portion located on the side of the partition plate facing the compression assembly; a float assembly movably disposed on the floating groove, wherein when the float assembly moves to a target position, the float assembly abuts against the sealing portion, and the float assembly and the groove wall of the floating groove enclose a back pressure chamber, the back pressure chamber communicating with the compression chamber; and a sealing element disposed between the sealing block and the partition plate.

[0007] The compressor provided in this embodiment of the utility model includes a partition plate, a compression assembly, a sealing block, a float assembly, and a sealing element. Specifically, the compression assembly includes a floating groove, and the float assembly is movably disposed in the floating groove.

[0008] Specifically, when the compressor is running, the float assembly moves towards the side where the partition plate is located. When the float assembly reaches the target position, it abuts against the sealing part, and the float assembly and the wall of the floating groove enclose a back pressure chamber. Since the back pressure chamber is connected to the compression chamber, a medium pressure can be introduced into the back pressure chamber during compressor operation. Under the action of the medium pressure, a certain axial force can be applied to the stationary scroll of the compression assembly to ensure the sealing between the stationary scroll and the moving scroll. In addition, since the float assembly abuts against the sealing part, a seal can be achieved between the high-pressure chamber (exhaust chamber) and the low-pressure chamber (intake chamber). When the compressor stops running, the float assembly moves away from the partition plate and separates from the sealing part, and the high-pressure chamber and the low-pressure chamber become connected.

[0009] By setting a seal between the sealing block and the partition plate, the sealing performance between the sealing block and the partition plate can be effectively improved. When the float assembly abuts against the sealing part, the sealing performance between the sealing block and the float assembly can be improved, thereby improving the sealing effect between high and low pressure. This significantly improves the problem of poor sealing between high and low pressure caused by factors such as partition plate ring welding, wear-resistant plate riveting, and wear-resistant plate deformation under high pressure differential conditions. It also reduces high-pressure refrigerant leakage and helps improve the compressor's capacity and energy efficiency.

[0010] In some technical solutions, optionally, the thickness h1 of the sealing part along the axial direction of the partition plate satisfies h1≥3mm.

[0011] In this technical solution, since the axial thickness of the sealing part is greater than or equal to 3mm, it is understandable that the thickness of the wear-resistant sheet in related technologies is relatively thin, generally around 1mm. In other words, by setting a thicker axial thickness for the sealing part that abuts against the float assembly, the structural strength of the sealing part and the sealing block as a whole can be significantly improved, reducing deformation of the sealing part, enhancing the sealing effect between the sealing block and the partition plate, and between the sealing block and the float assembly, ensuring effective sealing between high and low pressure, reducing leakage of high-pressure refrigerant, improving compressor energy efficiency, and also extending the service life of the sealing block.

[0012] In some technical solutions, optionally, a sealing groove is provided on the side of the sealing part away from the compression assembly, and at least a portion of the sealing element is located in the sealing groove.

[0013] In this technical solution, a sealing groove is provided on the side of the sealing part away from the compression assembly, in which at least part of the sealing element is embedded. This can improve the sealing effect between high and low pressure, significantly improve the problem of poor sealing between high and low pressure caused by factors such as circumferential welding of the partition plate and riveting of the wear-resistant sheet in related technologies, reduce high-pressure refrigerant leakage, and limit the sealing element, which is conducive to improving the installation stability of the sealing element and ensuring reliable sealing between the partition plate and the sealing block.

[0014] In addition, since a sealing groove is provided on the side of the sealing part away from the compression assembly, the sealing surface on the side of the sealing part away from the compression assembly can be tightly fitted with the partition plate while ensuring reliable installation of the sealing element. This forms a multi-seal structure between the sealing block and the partition plate, which is beneficial to further improve the sealing effect between high and low pressure.

[0015] In some technical solutions, optionally, along the axial direction of the partition plate, the thickness of the sealing part is h1, and the depth of the sealing groove is h2, wherein 0.2 < h2 / (h1-h2) < 0.5.

[0016] In this technical solution, it is understood that if the ratio of h2 to (h1-h2) is too small, i.e., less than or equal to 0.2, meaning the depth of the sealing groove is too shallow, the seal cannot be effectively limited, which can easily lead to seal failure after long-term use. If the ratio of h2 to (h1-h2) is too large, i.e., greater than or equal to 0.5, meaning the depth of the sealing groove is too deep, the structural strength of the sealing part will be reduced, and it will be prone to breakage during repeated contact with the floating plate assembly, thus reducing the service life of the sealing block.

[0017] Since the ratio of h2 to (h1-h2) is greater than 0.2 and less than 0.5, it is possible to effectively limit the sealing element while ensuring the structural strength of the sealing part, reducing the probability of the sealing part breaking, thereby ensuring the service life of the sealing block and improving the reliability of the compressor.

[0018] In some technical solutions, the sealing block may optionally include a mounting portion, which is located on the side of the sealing portion away from the compression assembly along the axial direction of the partition plate; wherein the partition plate has a mounting hole at its center, and the mounting portion extends into the mounting hole and connects with the partition plate.

[0019] In this technical solution, the sealing block is further defined as including a mounting part. Specifically, along the axial direction of the partition plate, the mounting part is located on the side of the sealing part away from the compression assembly.

[0020] The partition plate has a mounting hole in its center. The mounting part extends into the mounting hole and connects with the partition plate, thereby achieving a fixed assembly between the sealing block and the partition plate. Because the mounting part extends into the mounting hole, it helps to reduce the overall axial thickness of the partition plate and the sealing block, and reduce the space occupied by the partition plate and the sealing block inside the compressor.

[0021] In addition, since the sealing block includes a connected mounting part and a sealing part, it helps to improve the overall structural strength of the sealing block, reduce the deformation of the sealing block, further improve the sealing performance between high and low pressure, and reduce the leakage of high-pressure refrigerant.

[0022] In some technical solutions, optionally, the side of the sealing portion away from the compression assembly includes a sealing surface, which is located outside the sealing groove along the radial direction of the partition plate; wherein at least a portion of the sealing surface is in contact with the side of the partition plate facing the compression assembly.

[0023] In this technical solution, the sealing part includes a sealing surface on the side away from the compression assembly, wherein the sealing surface is located radially outside the sealing groove.

[0024] Since at least a portion of the sealing surface is in contact with the side of the partition plate facing the compression assembly, optionally, the side of the partition plate facing the compression assembly includes an abutment surface, and at least a portion of the sealing surface is in contact with the abutment surface. This allows for the formation of a multi-layer sealing structure between the sealing block and the partition plate, significantly improving the sealing effect between them, achieving effective sealing between high and low pressure, and further improving the problem of poor sealing between high and low pressure caused by factors such as partition plate circumferential welding and wear-resistant sheet riveting in related technologies. This reduces high-pressure refrigerant leakage and improves the compressor's capacity and energy efficiency.

[0025] In some technical solutions, optionally, the width of the sealing surface along the radial direction of the partition plate is t1, where t1 ≥ 2 mm.

[0026] In this technical solution, the radial width of the sealing surface is limited to a specific value range; specifically, the radial width of the sealing surface is greater than or equal to 2mm. Since the sealing surface is in contact with the side of the partition plate facing the compression assembly, meaning the radial width of the overlapping portion between the sealing surface and the side of the partition plate facing the compression assembly is greater than or equal to 2mm, the tight contact area between the sealing surface and the partition plate is increased. This further enhances the sealing effect between the sealing block and the partition plate, ensuring effective sealing between high and low pressure, reducing high-pressure refrigerant leakage, and improving the compressor's capacity and energy efficiency.

[0027] In some technical solutions, optionally, along the radial direction of the partition plate, the width of the sealing part is d1, the width of the mounting part is d2, and the width of the sealing surface is t1, wherein 0.2 < (d1-d2-2t1) / (2t1) < 0.5.

[0028] In this technical solution, it can be understood that (d1-d2-2t1) / 2 represents the radial width of the sealing groove. That is, along the radial direction of the partition plate, the width of the sealing groove is t2, where t2 / t1 is greater than 0.2 and less than 0.5.

[0029] If the ratio of (d1-d2-2t1) to (2t1) is too small, i.e. less than or equal to 0.2, meaning the radial width of the sealing groove is too narrow, the seal cannot be embedded in the sealing groove. If the ratio of (d1-d2-2t1) to (2t1) is too large, i.e. greater than or equal to 0.5, meaning the radial width of the sealing groove is too wide, the radial width of the sealing surface will be too narrow, resulting in less overlap between the sealing surface and the side of the partition plate facing the compression assembly, affecting the sealing effect between the sealing part and the partition plate.

[0030] Since the ratio of (d1-d2-2t1) to (2t1) is greater than 0.2 and less than 0.5, it is possible to ensure a tight fit between the sealing surface and the side of the partition plate facing the compression assembly while ensuring reliable installation of the seal, which is beneficial for achieving effective sealing between high and low pressure.

[0031] In some technical solutions, the mounting part may optionally be interference-fitted with the wall of the mounting hole; and / or the sealing groove may be constructed as an annular groove, located on the side of the sealing part closer to the mounting part along the radial direction of the partition plate.

[0032] In this technical solution, the mounting part and the mounting hole wall are interference-fitted, that is, the outer wall of the mounting part and the mounting hole wall are interference-fitted. In other words, the sealing block and the partition plate are connected by interference fit. This can achieve reliable assembly between the sealing block and the partition plate, while effectively reducing the deformation of the partition plate and the sealing block caused by the installation process. This is conducive to further improving the sealing effect between the partition plate and the sealing block, as well as between the sealing block and the floating plate assembly, thereby improving the energy efficiency of the compressor.

[0033] Since the sealing groove is an annular groove, the sealing element can be set as an annular sealing element (sealing ring), which is beneficial to further improve the sealing performance between the sealing block and the partition plate, thereby improving the sealing effect between high and low pressure. This significantly improves the problem of poor sealing between high and low pressure caused by factors such as partition plate ring welding, wear-resistant plate riveting, and wear-resistant plate deformation under high pressure differential conditions, reducing high-pressure refrigerant leakage and improving the compressor's capacity and energy efficiency.

[0034] Furthermore, since the annular groove is located on the side of the sealing part closer to the mounting part along the radial direction of the partition plate, the sealing surface area between the sealing part and the partition plate can be increased, thereby improving the sealing effect between the partition plate and the sealing part while ensuring reliable installation of the seal.

[0035] In some technical solutions, the mounting section may optionally include a mounting section and an extension section, wherein the mounting section is located between the extension section and the sealing section, and the mounting section is connected to the partition plate; wherein, along the radial direction of the partition plate, the width of the extension section is less than or equal to the width of the mounting section.

[0036] In this technical solution, the mounting section is defined as including a mounting segment and an extension segment. Specifically, the mounting segment is located between the extension segment and the sealing section, and the radial width of the extension segment is less than or equal to the radial width of the mounting segment. The mounting segment is connected to the partition plate, meaning that extending the mounting section into the exhaust chamber increases the axial height of the sealing block, thereby improving the overall structural rigidity of the sealing block, reducing deformation, and further enhancing the sealing effect between the sealing block and the partition plate, as well as between the sealing block and the float assembly, ensuring effective sealing between high and low pressure. Furthermore, because the mounting segment extends into the exhaust chamber, the distance between the exhaust passage of the sealing block and the compressor's exhaust pipe is shortened, which helps improve the compressor's exhaust efficiency.

[0037] In particular, when the radial width of the extension section is smaller than the radial width of the installation section, the overall structural strength of the sealing block can be improved to reduce deformation, while saving the material used for the sealing block, which is conducive to reducing the production cost of the compressor.

[0038] In some technical solutions, the sealing block may optionally include an exhaust channel that communicates with the compression chamber.

[0039] In this technical solution, the sealing block is further defined as including an exhaust channel, specifically, the exhaust channel is connected to the compression chamber.

[0040] Specifically, during compressor operation, when the pressure of the refrigerant compressed in the compression chamber reaches the discharge pressure, the high-pressure refrigerant flows out of the compression chamber and into the discharge chamber through the discharge passage, and is then discharged outside the casing. This improves the sealing effect between high and low pressure while ensuring reliable discharge of the compressor and maintaining its capacity.

[0041] In some technical solutions, the compression assembly may optionally include an exhaust port, and the compression chamber is connected to the exhaust channel through the exhaust port; wherein the minimum flow area of ​​the exhaust channel is greater than or equal to the flow area of ​​the exhaust port.

[0042] In this technical solution, the compression assembly also includes an exhaust port, wherein the compression chamber is connected to the exhaust channel through the exhaust port. That is, either the compression chamber or the exhaust channel is connected to the exhaust port. Specifically, during the operation of the compressor, when the pressure of the refrigerant compressed in the compression chamber reaches the exhaust pressure, the high-pressure refrigerant flows out of the compression chamber from the exhaust port and flows into the exhaust chamber through the exhaust channel, and is then discharged outside the casing.

[0043] Since the minimum flow area of ​​the exhaust passage is greater than or equal to the flow area of ​​the exhaust port, a reliable seal can be achieved between high and low pressure, reducing high-pressure refrigerant leakage and improving compressor energy efficiency. At the same time, it helps to reduce the flow resistance of the compressor during exhaust, ensuring the compressor's exhaust efficiency and thus ensuring the compressor's performance.

[0044] In some technical solutions, optionally, the exhaust passage includes a first exhaust section, which communicates with the compression chamber. Along the axial direction of the partition plate, the first exhaust section includes a first end and a second end facing away from each other, with the first end being closer to the compression assembly than the second end; wherein, along the radial direction of the partition plate, the width of the first end is greater than or equal to the width of the second end.

[0045] In this technical solution, the exhaust channel includes a first exhaust section, wherein the first exhaust section includes a first end and a second end that are opposite to each other along the axial direction of the partition plate, and the first end is closer to the compression assembly than the second end, that is, the first end is the lower end and the second end is the upper end.

[0046] The radial width of the first end is greater than or equal to the radial width of the second end. When the radial width of the first end is greater than the radial width of the second end, the first exhaust section is formed into a horn-shaped structure with a flared lower end. This guides the exhaust airflow when the compressor is discharging, reducing the exhaust airflow from flowing to both sides. This reduces flow resistance and improves exhaust efficiency, while also helping to further reduce leakage of high-pressure refrigerant and improve the compressor's capacity and energy efficiency.

[0047] Furthermore, when the radial width of the first end is equal to the radial width of the second end, that is, the first exhaust section is a straight section, it is beneficial to reduce the processing difficulty of the exhaust passage and reduce the manufacturing cost of the compressor.

[0048] In some technical solutions, optionally, the height of the first exhaust section is h3 along the axial direction of the partition plate, the width of the first end is d3 along the radial direction of the partition plate, and the width of the second end is d4, wherein 0≤(d3-d4) / (2h3)≤1.

[0049] In this technical solution, it can be understood that tanα = ((d3-d4) / 2) / h3, i.e., tanα = (d3-d4) / (2h3). Since (d3-d4) / (2h3) is between 0 and 1, it limits α to between 0° and 45°, thus limiting the inclination angle of the passage wall of the first exhaust section. It can be understood that if (d3-d4) / (2h3) is too large, i.e., greater than 1, i.e., α is greater than 45°, that is, the inclination angle of the passage wall of the first exhaust section is too large, increasing the flow resistance of the exhaust airflow and reducing the exhaust efficiency of the compressor.

[0050] By limiting (d3-d4) / (2h3) to between 0 and 1, it not only guides the exhaust airflow but also helps reduce the flow resistance of the exhaust airflow and improves the exhaust efficiency of the compressor.

[0051] In some technical solutions, the exhaust passage may optionally include a second exhaust section, which is located on the side of the first exhaust section away from the compression assembly and is connected to the first exhaust section.

[0052] In this technical solution, the exhaust passage is further defined as including a second exhaust section. Specifically, the second exhaust section is located on the side of the first exhaust section away from the compression assembly, and the second exhaust section is connected to the first exhaust section. Specifically, during the operation of the compressor, when the pressure of the refrigerant compressed in the compression chamber reaches the exhaust pressure, the high-pressure refrigerant flows out of the compression chamber, flows through the first exhaust section and the second exhaust section respectively, flows into the exhaust chamber, and is then discharged outside the casing.

[0053] By setting up a second exhaust section, the length of the exhaust passage is extended, thereby shortening the distance between the exhaust passage and the compressor's exhaust pipe, which helps to improve the compressor's exhaust efficiency.

[0054] In some technical solutions, the sealing block may optionally be a wear-resistant block; and / or the sealing element may include sealant or a sealing ring.

[0055] In this technical solution, because the sealing block is a wear-resistant block—meaning it is made of wear-resistant material—it possesses high wear resistance. During the repeated movement of the float assembly and its contact with the sealing part, wear on the sealing block is reduced. This ensures effective sealing between high and low pressure, extends the service life of the sealing block, and improves the reliability of the compressor. Optionally, the sealing block can be made of high-wear-resistant materials such as 45 steel or alloy steel.

[0056] The sealing element includes a sealing ring, which may optionally be an O-ring. In other words, the sealing element is arranged around the compressor, thereby further improving the sealing performance between the sealing block and the partition plate, enhancing the sealing effect between high and low pressure, reducing high-pressure refrigerant leakage, and ultimately improving the compressor's capacity and energy efficiency.

[0057] Alternatively, the sealant may include sealant. Specifically, if a sealing groove is provided on the side of the sealing part away from the compression assembly, sealant can be filled into the sealing groove to improve the sealing performance between the sealing block and the partition plate, thereby improving the sealing effect between high and low pressure. Furthermore, the sealant can connect the sealing block and the partition plate, thus increasing the connection strength between them, which is beneficial for improving the installation reliability of the sealing block and consequently improving the reliability of the compressor. Specific configurations can be made according to actual needs.

[0058] In some technical solutions, the compressor may optionally include a housing, a partition plate disposed within the housing and dividing the housing into an intake chamber and an exhaust chamber, a compression assembly disposed within the intake chamber, and the compression assembly including a moving scroll, a stationary scroll, and a back pressure plate, wherein the stationary scroll is located on the side of the moving scroll near the partition plate and forms a compression chamber with the moving scroll, the compression chamber being able to communicate with the exhaust chamber, and the back pressure plate is disposed on the side of the stationary scroll near the partition plate, a portion of the back pressure plate and a portion of the stationary scroll forming a floating groove.

[0059] In this technical solution, the housing is divided into an intake chamber and an exhaust chamber by a partition plate, and the compression assembly is located in the intake chamber.

[0060] The moving scroll and the stationary scroll form a compression chamber. Optionally, the stationary scroll has an exhaust port, and the back pressure plate has an exhaust flow path. When the compressor is running, the moving scroll rotates relative to the stationary scroll to compress the refrigerant in the compression chamber. When the pressure of the refrigerant in the compression chamber reaches the exhaust pressure, the compressed high-pressure refrigerant flows out from the exhaust port and flows into the exhaust chamber through the exhaust flow path of the back pressure plate and the exhaust channel of the sealing block. That is, the intake chamber is a low-pressure chamber, and the exhaust chamber is a high-pressure chamber.

[0061] Because a portion of the back pressure plate and a portion of the stationary scroll form a floating groove, when the float assembly moves to the target position, the float assembly, a portion of the back pressure plate, and a portion of the stationary scroll enclose and form a back pressure chamber. Since the back pressure chamber is connected to the compression chamber, intermediate pressure can be introduced into the back pressure chamber during compressor operation. Under the action of this intermediate pressure, a certain axial force can be applied to the stationary scroll of the compression assembly to ensure the sealing between the stationary scroll and the moving scroll.

[0062] According to a second aspect of this utility model, a refrigeration device is provided, including a compressor as provided in any of the above technical solutions, and thus possesses all the beneficial technical effects of the compressor, which will not be repeated here.

Detailed Implementation

[0072] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0073] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0074] The following reference Figures 1 to 5 The present invention will be described in some embodiments of the compressor 1 and refrigeration equipment provided.

[0075] In one embodiment according to this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a compressor 1 is proposed, comprising: a partition plate 10; a compression assembly 20, the compression assembly 20 including a floating groove 21 and a compression chamber 22; a sealing block 30 disposed on the partition plate 10, the sealing block 30 including a sealing part 32 located on the side of the partition plate 10 facing the compression assembly 20; a float assembly 40 movably disposed on the floating groove 21, wherein when the float assembly 40 moves to a target position, the float assembly 40 abuts against the sealing part 32, and the float assembly 40 and the groove wall of the floating groove 21 enclose a back pressure chamber 50, the back pressure chamber 50 communicating with the compression chamber 22; and a sealing element 60 disposed between the sealing block 30 and the partition plate 10.

[0076] The compressor 1 provided in this embodiment of the utility model includes a partition plate 10, a compression assembly 20, a sealing block 30, a float assembly 40, and a sealing element 60. Specifically, the compression assembly 20 includes a floating groove 21, and the float assembly 40 is movably disposed in the floating groove 21.

[0077] Specifically, when the compressor 1 is running, the float assembly 40 moves towards the side where the partition plate 10 is located. When the float assembly 40 moves to the target position, it abuts against the sealing part 32, and the float assembly 40 and the wall of the floating groove 21 enclose a back pressure chamber 50. Since the back pressure chamber 50 is connected to the compression chamber 22, a medium pressure can be introduced into the back pressure chamber 50 during the operation of the compressor 1. Under the action of the medium pressure, a certain axial force can be applied to the stationary scroll 25 of the compression assembly 20 to ensure the sealing between the stationary scroll 25 and the moving scroll 24. In addition, since the float assembly 40 abuts against the sealing part 32, a seal can be achieved between the high-pressure chamber (exhaust chamber 74) and the low-pressure chamber (intake chamber 72). When the compressor 1 stops running, the float assembly 40 moves away from the partition plate 10 and separates from the sealing part 32, and the high-pressure chamber and the low-pressure chamber are connected.

[0078] By setting a sealing element 60 between the sealing block 30 and the partition plate 10, the sealing performance between the sealing block 30 and the partition plate 10 can be effectively improved. When the float assembly 40 abuts against the sealing part 32, the sealing performance between the sealing block 30 and the float assembly 40 can be improved, thereby improving the sealing effect between high and low pressure. This significantly improves the problem of poor sealing between high and low pressure caused by factors such as partition plate ring welding, wear-resistant plate riveting, and wear-resistant plate deformation under high pressure differential conditions in related technologies, reduces high pressure refrigerant leakage, and helps to improve the capacity and energy efficiency of the compressor 1.

[0079] like Figure 3 and Figure 4 As shown, in some embodiments, optionally, the thickness h1 of the sealing portion 32 along the axial direction of the partition plate 10 satisfies h1≥3mm.

[0080] In this embodiment, since the axial thickness of the sealing part 32 is greater than or equal to 3mm, it is understood that the thickness of the wear-resistant sheet in related technologies is relatively thin, generally around 1mm. That is to say, by setting the axial thickness of the sealing part 32 that abuts against the float assembly 40 to be relatively thick, the overall structural strength of the sealing part 32 and the sealing block 30 can be significantly improved, the deformation of the sealing part 32 can be reduced, the sealing effect between the sealing block 30 and the partition plate 10, and between the sealing block 30 and the float assembly 40 can be improved, ensuring effective sealing between high and low pressure, reducing leakage of high-pressure refrigerant, improving the energy efficiency of the compressor 1, and at the same time, it is also beneficial to extend the service life of the sealing block 30.

[0081] Optionally, h1 can be any one of 3mm, 4mm and 5mm.

[0082] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the sealing portion 32 is provided with a sealing groove 322 on the side opposite to the compression assembly 20, and at least a portion of the sealing member 60 is located in the sealing groove 322.

[0083] In this embodiment, since the sealing part 32 is provided with a sealing groove 322 on the side away from the compression assembly 20, and at least part of the sealing element 60 is embedded in the sealing groove 322, the sealing effect between high and low pressure can be improved, significantly improving the problem of poor sealing between high and low pressure caused by factors such as the ring welding of the partition plate and the riveting of the wear-resistant sheet in the related technology. While reducing high-pressure refrigerant leakage, it can also limit the sealing element 60, which is conducive to improving the installation stability of the sealing element 60 and ensuring reliable sealing between the partition plate 10 and the sealing block 30.

[0084] Furthermore, since a sealing groove 322 is provided on the side of the sealing part 32 away from the compression assembly 20, the sealing surface 324 on the side of the sealing part 32 away from the compression assembly 20 can be tightly fitted with the partition plate 10 while ensuring reliable installation of the sealing element 60. This forms a multi-seal structure between the sealing block 30 and the partition plate 10, which is beneficial to further improve the sealing effect between high and low pressure.

[0085] like Figure 3 and Figure 4 As shown, in some embodiments, optionally, along the axial direction of the partition plate 10, the thickness of the sealing portion 32 is h1, and the depth of the sealing groove 322 is h2, wherein 0.2 < h2 / (h1-h2) < 0.5.

[0086] In this embodiment, it is understood that if the ratio of h2 to (h1-h2) is too small, i.e., less than or equal to 0.2, meaning the depth of the sealing groove 322 is too shallow, the seal 60 cannot be effectively limited, which may lead to seal failure after long-term use. If the ratio of h2 to (h1-h2) is too large, i.e., greater than or equal to 0.5, meaning the depth of the sealing groove 322 is too deep, the structural strength of the sealing part 32 will be reduced, and it may break during repeated contact with the floating plate assembly 40, reducing the service life of the sealing block 30.

[0087] Since the ratio of h2 to (h1-h2) is greater than 0.2 and less than 0.5, it is possible to effectively limit the sealing element 60 while ensuring the structural strength of the sealing part 32, reducing the probability of the sealing part 32 breaking, thereby ensuring the service life of the sealing block 30 and improving the reliability of the compressor 1.

[0088] Optionally, the ratio of h2 to (h1-h2) can be any one of 0.25, 0.3, 0.35, 0.4, and 0.45.

[0089] In some embodiments, the sealing block 30 may optionally include a mounting portion 34, which is disposed on the side of the sealing portion 32 away from the compression assembly 20 along the axial direction of the partition plate 10; wherein the partition plate 10 has a mounting hole 12 at its center, and the mounting portion 34 extends into the mounting hole 12 and is connected to the partition plate 10.

[0090] In this embodiment, the sealing block 30 is further defined as including a mounting portion 34. Specifically, along the axial direction of the partition plate 10, the mounting portion 34 is disposed on the side of the sealing portion 32 opposite to the compression assembly 20.

[0091] A mounting hole 12 is provided in the center of the partition plate 10. The mounting part 34 extends into the mounting hole 12 and is connected to the partition plate 10, thereby realizing the fixed assembly between the sealing block 30 and the partition plate 10. Since the mounting part 34 extends into the mounting hole 12, it is beneficial to reduce the overall axial thickness of the partition plate 10 and the sealing block 30, and reduce the space occupied by the partition plate 10 and the sealing block 30 inside the compressor 1.

[0092] Furthermore, since the sealing block 30 includes the connected mounting part 34 and sealing part 32, it is beneficial to improve the overall structural strength of the sealing block 30, reduce the deformation of the sealing block 30, further improve the sealing performance between high and low pressure, and reduce the leakage of high pressure refrigerant.

[0093] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, optionally, the side of the sealing portion 32 away from the compression assembly 20 includes a sealing surface 324, which is located outside the sealing groove 322 along the radial direction of the partition plate 10; wherein at least a portion of the sealing surface 324 is in contact with the side of the partition plate 10 facing the compression assembly 20.

[0094] In this embodiment, the sealing part 32 includes a sealing surface 324 on the side opposite to the compression assembly 20, wherein the sealing surface 324 is located radially outside the sealing groove 322.

[0095] Since at least a portion of the sealing surface 324 is in contact with the side of the partition plate 10 facing the compression assembly 20, optionally, the side of the partition plate 10 facing the compression assembly 20 includes an abutment surface, and at least a portion of the sealing surface 324 is in contact with the abutment surface. This allows for the formation of a multi-layer sealing structure between the sealing block 30 and the partition plate 10, significantly improving the sealing effect between the sealing block 30 and the partition plate 10, achieving effective sealing between high and low pressure, further improving the problem of poor sealing between high and low pressure caused by factors such as partition plate circumferential welding and wear-resistant sheet riveting in related technologies, reducing high-pressure refrigerant leakage, and improving the capacity and energy efficiency of the compressor 1.

[0096] like Figure 3 and Figure 4 As shown, in some embodiments, optionally, the width of the sealing surface 324 along the radial direction of the partition plate 10 is t1, wherein t1 ≥ 2 mm.

[0097] In this embodiment, the radial width of the sealing surface 324 is limited to a specific value range. Specifically, the radial width of the sealing surface 324 is greater than or equal to 2 mm. Since the sealing surface 324 is in contact with the side of the partition plate 10 facing the compression assembly 20, that is, the radial width of the overlapping portion between the sealing surface 324 and the side of the partition plate 10 facing the compression assembly 20 is greater than or equal to 2 mm, the tight contact area between the sealing surface 324 and the partition plate 10 is increased, thereby further improving the sealing effect between the sealing block 30 and the partition plate 10, ensuring effective sealing between high and low pressure, reducing leakage of high-pressure refrigerant, and improving the capacity and energy efficiency of the compressor 1.

[0098] Optionally, t1 can be any one of 2mm, 3mm, 4mm and 5mm.

[0099] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, optionally, along the radial direction of the partition plate 10, the width of the sealing part 32 is d1, the width of the mounting part 34 is d2, and the width of the sealing surface 324 is t1, wherein 0.2 < (d1-d2-2t1) / (2t1) < 0.5.

[0100] In this embodiment, it can be understood that (d1-d2-2t1) / 2 represents the radial width of the sealing groove 322, that is, the width of the sealing groove 322 along the radial direction of the partition plate 10 is t2, wherein t2 / t1 is greater than 0.2 and less than 0.5.

[0101] If the ratio of (d1-d2-2t1) to (2t1) is too small, i.e. less than or equal to 0.2, meaning the radial width of the sealing groove 322 is too narrow, the seal 60 cannot be embedded in the sealing groove 322. If the ratio of (d1-d2-2t1) to (2t1) is too large, i.e. greater than or equal to 0.5, meaning the radial width of the sealing groove 322 is too wide, the radial width of the sealing surface 324 is correspondingly too narrow, resulting in less overlap between the sealing surface 324 and the side of the partition plate 10 facing the compression assembly 20, affecting the sealing effect between the sealing part 32 and the partition plate 10.

[0102] Since the ratio of (d1-d2-2t1) to (2t1) is greater than 0.2 and less than 0.5, it is possible to ensure a tight fit between the sealing surface 324 and the side of the partition plate 10 facing the compression assembly 20 while ensuring reliable installation of the seal 60, which is beneficial for achieving effective sealing between high and low pressure.

[0103] Optionally, (d1-d2-2t1) / (2t1) can be any one of 0.25, 0.3, 0.35, 0.4 and 0.45.

[0104] Optionally, the mounting part 34 and the sealing part 32 are integrated into one structure, which is beneficial to further improve the overall structural strength of the sealing block 30, extend the service life of the sealing block 30, facilitate the mass production of the sealing block 30, and thus help reduce the production cost of the compressor 1.

[0105] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the mounting portion 34 is interference-fitted with the wall of the mounting hole 12; and / or, the sealing groove 322 is configured as an annular groove, located on the side of the sealing portion 32 near the mounting portion 34 along the radial direction of the partition plate 10.

[0106] In this embodiment, since the mounting part 34 and the wall of the mounting hole 12 are interference-fitted, that is, the outer wall of the mounting part 34 and the wall of the mounting hole 12 are interference-fitted, the sealing block 30 and the partition plate 10 are connected by interference fit. This enables reliable assembly between the sealing block 30 and the partition plate 10, while effectively reducing the deformation of the partition plate 10 and the sealing block 30 during the installation process. This is beneficial to further improve the sealing effect between the partition plate 10 and the sealing block 30, and between the sealing block 30 and the floating plate assembly 40, thereby improving the energy efficiency of the compressor 1.

[0107] Since the sealing groove 322 is an annular groove, the sealing element 60 can be set as an annular sealing element (sealing ring), which is beneficial to further improve the sealing performance between the sealing block 30 and the partition plate 10, thereby improving the sealing effect between high and low pressure. This significantly improves the problem of poor sealing between high and low pressure caused by factors such as partition plate ring welding, wear-resistant plate riveting, and wear-resistant plate deformation under high pressure differential conditions in related technologies, reduces high pressure refrigerant leakage, and improves the capacity and energy efficiency of the compressor 1.

[0108] Furthermore, since the annular groove is located on the side of the sealing part 32 close to the mounting part 34, the area of ​​the sealing surface between the sealing part 32 and the partition plate 10 can be increased, thereby improving the sealing effect between the partition plate 10 and the sealing part 32 while ensuring reliable installation of the sealing element 60.

[0109] like Figure 3 As shown, in some embodiments, optionally, the mounting portion 34 includes a mounting section 342 and an extension section 344, wherein the mounting section 342 is disposed between the extension section 344 and the sealing portion 32, and the mounting section 342 is connected to the partition plate 10; wherein, along the radial direction of the partition plate 10, the width of the extension section 344 is less than or equal to the width of the mounting section 342.

[0110] In this embodiment, the mounting portion 34 is defined as including a mounting section 342 and an extension section 344. Specifically, the mounting section 342 is disposed between the extension section 344 and the sealing portion 32, and the radial width of the extension section 344 is less than or equal to the radial width of the mounting section 342. The mounting section 342 is connected to the partition plate 10. That is, extending the mounting portion 34 into the exhaust chamber 74 by a portion increases the axial height of the sealing block 30, thereby improving the overall structural rigidity of the sealing block 30, reducing deformation of the sealing block 30, and further improving the sealing effect between the sealing block 30 and the partition plate 10, as well as between the sealing block 30 and the float assembly 40, ensuring effective sealing between high and low pressure. Furthermore, since the mounting portion 34 extends into the exhaust chamber 74 by a portion, the distance between the exhaust passage 36 of the sealing block 30 and the exhaust pipe of the compressor 1 is shortened, which is beneficial to improving the exhaust efficiency of the compressor 1.

[0111] In the case where the radial width of the extension section 344 is smaller than the radial width of the mounting section 342, the overall structural strength of the sealing block 30 can be improved to reduce deformation, while saving the material used for the sealing block 30, which is beneficial to reducing the production cost of the compressor 1.

[0112] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the sealing block 30 may optionally include an exhaust channel 36, which communicates with the compression chamber 22.

[0113] In this embodiment, the sealing block 30 is further defined as including an exhaust passage 36, which is specifically connected to the compression chamber 22.

[0114] Specifically, during the operation of compressor 1, when the pressure of the refrigerant compressed in the compression chamber 22 reaches the discharge pressure, the high-pressure refrigerant flows out of the compression chamber 22 and into the discharge chamber 74 through the discharge passage 36, and then is discharged to the outside of the casing 70. This can improve the sealing effect between high and low pressure while ensuring reliable discharge of compressor 1 and guaranteeing the capacity of compressor 1.

[0115] like Figure 1 and Figure 2 As shown, in some embodiments, the compression assembly 20 may optionally include an exhaust port 23, and the compression chamber 22 is connected to the exhaust channel 36 through the exhaust port 23; wherein the minimum flow area of ​​the exhaust channel 36 is greater than or equal to the flow area of ​​the exhaust port 23.

[0116] In this embodiment, the compression assembly 20 also includes an exhaust port 23, wherein the compression chamber 22 is connected to the exhaust passage 36 through the exhaust port 23. That is, either the compression chamber 22 or the exhaust passage 36 is connected to the exhaust port 23. Specifically, during the operation of the compressor 1, when the pressure of the refrigerant compressed in the compression chamber 22 reaches the exhaust pressure, the high-pressure refrigerant flows out of the compression chamber 22 from the exhaust port 23 and flows into the exhaust chamber 74 through the exhaust passage 36, and is then discharged outside the housing 70.

[0117] Since the minimum flow area of ​​the exhaust passage 36 is greater than or equal to the flow area of ​​the exhaust port 23, a reliable seal can be achieved between high and low pressure, reducing high-pressure refrigerant leakage and improving the energy efficiency of compressor 1. At the same time, it helps to reduce the flow resistance of compressor 1 during exhaust, ensuring the exhaust efficiency of compressor 1, and thus ensuring the performance of compressor 1.

[0118] Optionally, the minimum diameter of the exhaust passage 36 is greater than or equal to the diameter of the exhaust port 23.

[0119] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the exhaust passage 36 includes a first exhaust section 362, which communicates with the compression chamber 22. Along the axial direction of the partition plate 10, the first exhaust section 362 includes a first end 364 and a second end 366 facing away from each other. The first end 364 is closer to the compression assembly 20 than the second end 366. In the radial direction of the partition plate 10, the width of the first end 364 is greater than or equal to the width of the second end 366.

[0120] In this embodiment, since the exhaust passage 36 includes a first exhaust section 362, wherein the first exhaust section 362 includes a first end 364 and a second end 366 that are opposite to each other along the axial direction of the partition plate 10, and the first end 364 is closer to the compression assembly 20 than the second end 366, that is, the first end 364 is the lower end and the second end 366 is the upper end.

[0121] The radial width of the first end 364 is greater than or equal to the radial width of the second end 366. When the radial width of the first end 364 is greater than the radial width of the second end 366, the first exhaust section 362 is formed into a horn-shaped structure with a flared lower end. This guides the exhaust airflow when the compressor 1 is discharging, reducing the exhaust airflow from flowing to both sides. This reduces flow resistance and improves exhaust efficiency, while also helping to further reduce leakage of high-pressure refrigerant and improve the capacity and energy efficiency of the compressor 1.

[0122] Furthermore, when the radial width of the first end 364 is equal to the radial width of the second end 366, that is, the first exhaust section 362 is a straight section, it is beneficial to reduce the processing difficulty of the exhaust passage 36 and reduce the manufacturing cost of the compressor 1.

[0123] like Figure 3 and Figure 4 As shown, in some embodiments, optionally, the height of the first exhaust section 362 along the axial direction of the partition plate 10 is h3, the width of the first end 364 along the radial direction of the partition plate 10 is d3, and the width of the second end 366 is d4, wherein 0≤(d3-d4) / (2h3)≤1.

[0124] In this embodiment, it can be understood that tanα = ((d3-d4) / 2) / h3, i.e., tanα = (d3-d4) / (2h3). Since (d3-d4) / (2h3) is between 0 and 1, it limits α to between 0° and 45°, thus limiting the inclination angle of the passage wall of the first exhaust section 362. It can be understood that if (d3-d4) / (2h3) is too large, i.e., greater than 1, i.e., α is greater than 45°, that is, the inclination angle of the passage wall of the first exhaust section 362 is too large, increasing the flow resistance of the exhaust airflow and reducing the exhaust efficiency of the compressor 1.

[0125] By limiting (d3-d4) / (2h3) to between 0 and 1, it not only guides the exhaust airflow but also helps to reduce the flow resistance of the exhaust airflow and improve the exhaust efficiency of compressor 1.

[0126] like Figure 1 and Figure 3 As shown, in some embodiments, the exhaust passage 36 may optionally include a second exhaust section 368, which is located on the side of the first exhaust section 362 away from the compression assembly 20 and is in communication with the first exhaust section 362.

[0127] In this embodiment, the exhaust passage 36 further includes a second exhaust section 368. Specifically, the second exhaust section 368 is located on the side of the first exhaust section 362 away from the compression assembly 20, and the second exhaust section 368 is connected to the first exhaust section 362. Specifically, during the operation of the compressor 1, when the pressure of the refrigerant compressed in the compression chamber 22 reaches the exhaust pressure, the high-pressure refrigerant flows out of the compression chamber 22, flows through the first exhaust section 362 and the second exhaust section 368 respectively, flows into the exhaust chamber 74, and is then discharged outside the housing 70.

[0128] By setting a second exhaust section 368, the length of the exhaust passage 36 is extended, thereby shortening the distance between the exhaust passage 36 and the exhaust pipe of the compressor 1, which is beneficial to improving the exhaust efficiency of the compressor 1.

[0129] Optionally, the flow area of ​​the second exhaust section 368 is less than or equal to the flow area of ​​the first exhaust section 362.

[0130] Optionally, the flow area of ​​the second exhaust section 368 is larger than the flow area of ​​the first exhaust section 362.

[0131] In some embodiments, the sealing block 30 may be a wear-resistant block; and / or the sealing element 60 may include sealant or a sealing ring.

[0132] In this embodiment, since the sealing block 30 is a wear-resistant block, meaning it is made of a wear-resistant material, it possesses high wear resistance. During the repeated movement of the float assembly 40 and its contact with the sealing part 32, wear on the sealing block 30 is reduced. This ensures effective sealing between high and low pressures while extending the service life of the sealing block 30 and improving the reliability of the compressor 1. Optionally, the sealing block 30 can be made of high-wear-resistant materials such as 45 steel or alloy steel.

[0133] The seal 60 includes a sealing ring, which may optionally be an O-ring. In other words, the seal 60 is arranged around the sealing block 30, thereby further improving the sealing performance between the sealing block 30 and the partition plate 10, enhancing the sealing effect between high and low pressure, reducing high-pressure refrigerant leakage, and thus contributing to improving the capacity and energy efficiency of the compressor 1.

[0134] Alternatively, the seal 60 may include sealant. Specifically, if a sealing groove 322 is provided on the side of the sealing portion 32 facing away from the compression assembly 20, sealant can be filled into the sealing groove 322 to improve the sealing performance between the sealing block 30 and the partition plate 10, thereby improving the sealing effect between the high and low pressure. Furthermore, the sealant can connect the sealing block 30 and the partition plate 10, thereby increasing the connection strength between them, which is beneficial to improving the installation reliability of the sealing block 30, and thus improving the reliability of the compressor 1. The specific configuration can be adjusted according to actual needs.

[0135] like Figure 1 and Figure 2 As shown, in some embodiments, the compressor 1 may optionally include a housing 70, a partition plate 10 disposed within the housing 70, dividing the housing 70 into an intake chamber 72 and an exhaust chamber 74, and a compression assembly 20 disposed within the intake chamber 72. The compression assembly 20 includes a moving scroll 24, a stationary scroll 25, and a back pressure plate 26. The stationary scroll 25 is located on the side of the moving scroll 24 near the partition plate 10 and forms a compression chamber 22 with the moving scroll 24. The compression chamber 22 can communicate with the exhaust chamber 74. The back pressure plate 26 is disposed on the side of the stationary scroll 25 near the partition plate 10, and a portion of the back pressure plate 26 and a portion of the stationary scroll 25 form a floating groove 21.

[0136] In this embodiment, since the partition plate 10 divides the housing 70 into an intake chamber 72 and an exhaust chamber 74, the compression assembly 20 is disposed in the intake chamber 72.

[0137] The moving scroll 24 and the stationary scroll 25 form a compression chamber 22. Optionally, the stationary scroll 25 is provided with an exhaust port 23, and the back pressure plate 26 is provided with an exhaust flow path. When the compressor 1 is running, the moving scroll 24 rotates relative to the stationary scroll 25 to compress the refrigerant in the compression chamber 22. When the pressure of the refrigerant in the compression chamber 22 reaches the exhaust pressure, the compressed high-pressure refrigerant flows out from the exhaust port 23 and flows into the exhaust chamber 74 through the exhaust flow path of the back pressure plate 26 and the exhaust channel 36 of the sealing block 30. That is, the intake chamber 72 is a low-pressure chamber, and the exhaust chamber 74 is a high-pressure chamber.

[0138] Since a portion of the back pressure plate 26 and a portion of the stationary scroll 25 form a floating groove 21, when the float assembly 40 moves to the target position, the float assembly 40, a portion of the back pressure plate 26, and a portion of the stationary scroll 25 enclose and form a back pressure cavity 50. Because the back pressure cavity 50 is connected to the compression cavity 22, intermediate pressure can be introduced into the back pressure cavity 50 during compressor 1 operation. Under the action of this intermediate pressure, a certain axial force can be applied to the stationary scroll 25 of the compression assembly 20 to ensure the sealing between the stationary scroll 25 and the moving scroll 24.

[0139] Optionally, the float assembly 40 includes a first float, a second float, and a sealing cup, wherein the second float is connected to the first float, and a portion of the second float is located on the side of the first float near the compression chamber 22. When the float assembly 40 moves to the target position, the first float abuts against the sealing part 32.

[0140] The sealing cup is positioned between the first float plate and the second float plate, and the two ends of the sealing cup in the radial direction of the partition plate 10 abut against the back pressure plate 26 and the stationary vortex plate 25, respectively, thereby ensuring the sealing of the back pressure cavity 50.

[0141] According to a second aspect of the present invention, a refrigeration device is provided, including a compressor 1 as provided in any of the above embodiments, and thus possesses all the beneficial technical effects of the compressor 1, which will not be repeated here.

[0142] Alternatively, the refrigeration equipment may include air conditioners, refrigerators, or freezers.

[0143] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, optionally, the compressor 1 includes a partition plate 10, a compression assembly 20, a sealing block 30, a float assembly 40, and a seal 60. Specifically, the compression assembly 20 includes a floating groove 21, and the float assembly 40 is movably disposed in the floating groove 21.

[0144] Specifically, when the compressor 1 is running, the float assembly 40 moves towards the side where the partition plate 10 is located. When the float assembly 40 moves to the target position, it abuts against the sealing part 32, and the float assembly 40 and the wall of the floating groove 21 enclose a back pressure chamber 50. Since the back pressure chamber 50 is connected to the compression chamber 22, a medium pressure can be introduced into the back pressure chamber 50 during the operation of the compressor 1. Under the action of the medium pressure, a certain axial force can be applied to the stationary scroll 25 of the compression assembly 20 to ensure the sealing between the stationary scroll 25 and the moving scroll 24. In addition, since the float assembly 40 abuts against the sealing part 32, a seal can be achieved between the high-pressure chamber (exhaust chamber 74) and the low-pressure chamber (intake chamber 72). When the compressor 1 stops running, the float assembly 40 moves away from the partition plate 10 and separates from the sealing part 32, and the high-pressure chamber and the low-pressure chamber are connected.

[0145] By setting a sealing element 60 between the sealing block 30 and the partition plate 10, the sealing performance between the sealing block 30 and the partition plate 10 can be effectively improved. When the float assembly 40 abuts against the sealing part 32, the sealing performance between the sealing block 30 and the float assembly 40 can be improved, thereby improving the sealing effect between high and low pressure. This significantly improves the problem of poor sealing between high and low pressure caused by factors such as partition plate ring welding, wear-resistant plate riveting, and wear-resistant plate deformation under high pressure differential conditions in related technologies, reduces high pressure refrigerant leakage, and helps to improve the capacity and energy efficiency of the compressor 1.

[0146] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the sealing part 32 is provided with a sealing groove 322 on the side opposite to the compression assembly 20, and at least a portion of the sealing member 60 is located in the sealing groove 322.

[0147] In this embodiment, since the sealing part 32 is provided with a sealing groove 322 on the side away from the compression assembly 20, and at least part of the sealing element 60 is embedded in the sealing groove 322, the sealing effect between high and low pressure can be improved, significantly improving the problem of poor sealing between high and low pressure caused by factors such as the ring welding of the partition plate and the riveting of the wear-resistant sheet in the related technology. While reducing high-pressure refrigerant leakage, it can also limit the sealing element 60, which is conducive to improving the installation stability of the sealing element 60 and ensuring reliable sealing between the partition plate 10 and the sealing block 30.

[0148] Furthermore, since a sealing groove 322 is provided on the side of the sealing part 32 away from the compression assembly 20, the sealing surface 324 on the side of the sealing part 32 away from the compression assembly 20 can be tightly fitted with the partition plate 10 while ensuring reliable installation of the sealing element 60. This forms a multi-seal structure between the sealing block 30 and the partition plate 10, which is beneficial to further improve the sealing effect between high and low pressure.
