DETAILED DESCRIPTION

[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0039] like Figure 1-Figure 7 As shown, the exhaust assembly 100 of the compressor according to the embodiment of the utility model includes a first scroll 2 and an exhaust valve plate 3 . The first scroll 2 has an exhaust hole 21 . The exhaust valve plate 3 is used to open and close the exhaust hole 21 .

[0040] Among them, the first scroll 2 can be constructed in a disc shape, and the first scroll 2 includes a base plate and a volute. During operation, the first scroll 2 can translate around a predetermined axis and drive the fluid to flow from the outside to the inside along the radial direction of the first scroll 2, and when the exhaust valve plate 3 opens the exhaust hole 21, the fluid is driven to be sent out from the exhaust hole 21.

[0041] In addition, the exhaust valve plate 3 has a convex portion, and the convex portion is sealed with the first scroll 2 when the exhaust valve plate 3 is closed. When the exhaust valve plate 3 is closed, the cooperation between the convex portion and the first scroll 2 can be utilized to improve the sealing effect of the exhaust hole 21. Relative to the cooperation between the surface of the exhaust valve plate 3 and the surface of the first scroll 2, by providing the convex portion, the sealing effect between the exhaust valve plate 3 and the first scroll 2 can be improved, and the deformation of the exhaust valve plate 3 resulting in failure of the seal between the exhaust valve plate 3 and the first scroll 2 can be avoided. It can be ensured that when the exhaust valve plate 3 is closed, the exhaust hole 21 can be effectively closed, thereby improving the sealing effect of the exhaust hole 21.

[0042] According to the exhaust assembly 100 of the compressor of the embodiment of the utility model, the exhaust valve plate 3 is provided with a convex portion, which can improve the sealing effect of the exhaust valve plate 3 on the exhaust hole 21. In addition, the exhaust valve plate 3 in the utility model can be integrally formed, for example, the convex portion is stamped on the exhaust valve plate 3.

[0043] The sealing structure between the convex portion and the first scroll 2 in the present invention includes but is not limited to the following embodiments.

[0044] In the first embodiment, the convex portion includes a first convex ring 31, which is configured in a ring shape. When the exhaust valve plate 3 is closed, the first convex ring 31 is sealed with the first scroll 2, and a labyrinth sealing structure can be formed between the exhaust valve plate 3 and the first scroll 2, thereby achieving a stable seal between the exhaust valve plate 3 and the first scroll 2 and avoiding sealing failure caused by deformation of the exhaust valve plate 3.

[0045] When the exhaust valve plate 3 is closed, the first convex ring 31 is located on the inner side of the exhaust hole 21 and extends along the opening periphery of the exhaust hole 21. The first convex ring 31 cooperates with the opening of the exhaust hole 21 to achieve effective sealing of the exhaust valve plate 3 to the exhaust hole 21, wherein the first convex ring 31 can be formed by pressing on the exhaust valve plate 3, specifically, the exhaust valve plate 3 has a first surface and a second surface opposite to each other, wherein the first surface of the exhaust valve plate 3 can be opposite to the surface of the first scroll 2, the first convex ring 31 can be constructed by a part of the exhaust valve plate 3 protruding from the first surface, and a groove can be formed on the second surface of the exhaust valve plate 3. Of course, the first convex ring 31 can also be configured to form a bump on the exhaust valve plate 3, etc.

[0046] In the second embodiment, the convex portion also includes a second convex ring 32, which is configured in a ring shape. When the exhaust valve plate 3 is closed, the second convex ring 32 is opposite to the surface of the first scroll 2 and seals with it, and can form a labyrinth sealing structure between the exhaust valve plate 3 and the first scroll 2, thereby achieving stable sealing between the exhaust valve plate 3 and the first scroll 2 and avoiding sealing failure caused by deformation of the exhaust valve plate 3.

[0047] The surface of the first scroll 2 is provided with a clearance groove 22, which is configured as a ring around the exhaust hole 21. When the exhaust valve plate 3 is closed, the second convex ring 32 is located in the clearance groove 22. The labyrinth seal structure between the exhaust valve plate 3 and the first scroll 2 can be further optimized. The second convex ring 32 can be formed by pressing on the exhaust valve plate 3. Specifically, the exhaust valve plate 3 has a relative second surface and a second surface, wherein the second surface of the exhaust valve plate 3 can be opposite to the surface of the first scroll 2. The second convex ring 32 can be constructed by a part of the exhaust valve plate 3 protruding from the second surface, and a groove is formed on the second surface of the exhaust valve plate 3. Of course, the second convex ring 32 can also be configured to form a bump on the exhaust valve plate 3, etc.

[0048] A third embodiment mode, such as Figure 3 and Figure 5 As shown, the convex portion includes a first convex ring 31 and a second convex ring 32. The first convex ring 31 is configured in an annular shape. When the exhaust valve plate 3 is closed, the first convex ring 31 is located at the inner side of the exhaust hole 21 and extends along the opening periphery of the exhaust hole 21. The second convex ring 32 is configured in an annular shape. The second convex ring 32 surrounds the first convex ring 31. When the exhaust valve plate 3 is closed, the second convex ring 32 is opposite to the surface of the first scroll 2 and is sealed. The surface of the first scroll 2 is provided with a clearance groove 22. The clearance groove 22 is configured in an annular shape surrounding the exhaust hole 21. When the exhaust valve plate 3 is closed, the second convex ring 32 is located in the clearance groove 22.

[0049] In addition, the convex portion in the utility model can also be set in other forms, for example, the convex portion also includes a third convex ring, and the third convex ring is set in a ring shape surrounding the second convex ring 32. In addition, a groove adapted to the third convex ring can be set on the surface of the first scroll 2, and the exhaust valve plate 3 is located in the groove when it is closed.

[0050] In the present invention, when the exhaust valve plate 3 contacts the first scroll 2, the exhaust hole 21 on the first scroll 2 is closed. Considering the actual processing error and the deformation of the valve plate in later use, the exhaust hole 21 may not be well closed. Therefore, a convex portion is added to the exhaust valve plate 3, and a concave pit can be correspondingly provided on the first scroll 2. The design of multiple annular concave and convex platforms can effectively improve the sealing performance of the exhaust valve plate 3, reduce the premature leakage of the refrigerant during the compression process, and help improve the compression performance of the compressor.

[0051] Among them, the ratio of the protrusion height of the convex part to the thickness of the exhaust valve plate 3 in the utility model can be set to be greater than 0 and less than or equal to 3. For example, the ratio is set to 0.5, 1, 1.6, 2, 2.6 or 3, that is, the protrusion height of the convex part can be less than the thickness of the exhaust valve plate 3, or it can be the same as the thickness of the exhaust valve plate 3, or it can be greater than the height of the exhaust valve plate 3. Correspondingly, the groove depth of the make way groove 22 formed on the first scroll 2 is greater than or equal to the protrusion height of the convex part to ensure that the exhaust valve plate 3 is closed. When the convex part is located in the make way groove 22, the exhaust valve plate 3 fits with the surface of the first scroll 2 to achieve effective sealing.

[0052] Preferably, the ratio is greater than or equal to 2 and less than or equal to 3, and the protruding height of the convex portion is relatively large. When the exhaust valve plate 3 is closed, the convex portion can be inserted into the make way groove 22, and the convex portion is not easy to fall out of the make way groove 22, which can enhance the sealing of the high-pressure cavity before exhaust during the operation of the compressor.

[0053] like Figure 1 , Figure 2 , Figure 4 and 6 As shown, in some embodiments of the utility model, a limit block 4 is further included, the limit block 4 is connected to the first scroll 2, and has a limit portion 41 that is tilted relative to the surface of the first scroll 2, and the exhaust valve plate 3 is limited by the limit portion 41 when it is opened. The limit block 4 can be used to limit the exhaust valve plate 3, and the limit portion 41 can be set on the side of the exhaust valve plate 3 away from the first scroll 2. When the exhaust valve plate 3 is opened, the exhaust valve plate 3 is supported by the limit portion 41 to limit the opening angle of the exhaust valve plate 3, so as to improve the stability of the exhaust valve plate 3.

[0054] The limiting portion 41 is provided with a through hole 411. By providing the through hole 411, a sound-absorbing structure can be formed, which can reduce the noise during the opening and closing process of the exhaust valve plate 3 and optimize the noise reduction effect of the exhaust assembly 100.

[0055] In addition, the first scroll 2 in the utility model can have multiple exhaust holes 21. In some embodiments, the exhaust valve plate 3 includes a fixed portion 33 and multiple movable portions 34, the fixed portion 33 is connected to the first scroll 2, and the multiple movable portions 34 are connected to the fixed portion 33 and distributed around the fixed portion 33. The limit block 4 includes a positioning portion 42 and multiple limiting portions 41, the positioning portion 42 is connected to the fixed portion 33, and the multiple limiting portions 41 correspond to the multiple movable portions 34. The exhaust valve plate 3 can be installed on the first scroll 2 through the fixed portion 33, and the multiple movable portions 34 can be used to open and close the multiple exhaust holes 21.

[0056] Among them, Figure 1 As shown, the first scroll 2 in the utility model can have four exhaust holes 21, and the corresponding limit block 4 can also be set to a four-leaf clover structure. In addition, a certain number of through holes 411 are opened in the limit portion 41 of the limit block 4, which can weaken the noise during the process of the exhaust valve plate 3 dynamically contacting the limit block 4.

[0057] Specifically, Figure 6 As shown, there are six through holes 411, and the six through holes 411 are evenly spaced apart. The four-leaf clover structure includes four limit blocks 4. Correspondingly, the four limit blocks 4 are each provided with six through holes 411, which can weaken the noise of the exhaust valve plate 3 when it contacts each limit block 4. Thus, effective noise reduction is achieved through the porous silencer structure, thereby improving the noise reduction effect during the exhaust process, and the number of through holes 411 is four, five, etc.

[0058] like Figure 1 and Figure 7 As shown, in some embodiments of the utility model, a rear cover 5 is further included, which covers the outside of the first scroll 2 and is provided with an exhaust cavity 51 that can be connected to the exhaust hole 21, and the rear cover 5 is provided with an exhaust channel 52. The exhaust channel 52 can be used for exhaust of the exhaust assembly 100, so that the fluid discharged from the exhaust hole 21 can be guided out by the exhaust channel 52. Among them, a cyclone separation structure 53 is provided in the exhaust channel 52. Therefore, the cyclone separation structure 53 is used to achieve oil and gas separation during the exhaust process, so as to avoid lubricating oil or other liquid fluids from affecting the exhaust flow.

[0059] The cyclone separation structure 53 may include an air inlet 531, an air outlet 532 and an oil outlet 533. The fluid can enter the cyclone separation structure 53 along the tangential direction through the air inlet 531, and under the centrifugal effect, the heavier oil is separated from the fluid, and the airflow in the fluid is sent out through the air outlet 532, and the oil in the fluid is sent out through the oil outlet 533, thereby realizing the separation of oil and gas in the fluid.

[0060] In addition, if Figure 7As shown, the rear cover 5 is further provided with an oil collecting chamber 54, and the exhaust passage 52 is connected to the oil collecting chamber 54. The oil collecting chamber 54 can collect the oil separated by the cyclone separation structure 53 to prevent the oil from entering the exhaust passage 52 again and affecting the displacement of the exhaust passage 52. The outlet end of the oil collecting chamber 54 is connected to other lubrication pipelines, and the oil collected in the fluid is used for lubrication of various structures in the compressor, thereby realizing the reuse of lubricating oil.

[0061] Optionally, the rear cover 5 is provided with at least two exhaust channels 52. By providing at least two exhaust channels 52, the exhaust flow rate can be increased to increase the exhaust volume of the exhaust assembly 100. For example, there are two or three exhaust channels 52.

[0062] In addition, if Figure 7 As shown, the rear cover 5 may also be provided with two exhaust channels 52, and the two exhaust channels 52 are symmetrically distributed. Rapid exhaust is achieved, and turbulence or airflow impact is reduced. Two exhaust channels 52 may be provided on the rear cover 5, and the interior of the exhaust channel 52 may be designed as a cyclone separator structure, which helps to improve the oil-gas separation efficiency. In addition, the two exhaust channels 52 are symmetrically distributed in space, which helps to improve the overall structural strength of the rear cover 5 under high pressure.

[0063] Two exhaust channels 52 are arranged on the rear cover 5, which can significantly increase the exhaust volume per unit time, and help reduce the exhaust pressure loss of the compressor, saving energy consumption. After the fluid enters from the air inlet 531 on the exhaust channel 52, a rotating gas-liquid rotating flow is formed. Due to the different densities of the lubricating oil and the refrigerant gas, the centrifugal forces they are subjected to during the rotation process are different, and the lubricating oil is thrown to the wall in this process, and flows to the oil collecting chamber 54 under the action of gravity. The refrigerant gas is discharged through the exhaust pipe outlet at the center under the action of strong swirl. Oil and gas separation is achieved under the efficient separation action of cyclone separation.

[0064] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the first scroll 2 may have a plurality of exhaust holes 21, and the exhaust valve plate 3 includes a fixed portion 33 and a plurality of movable portions 34, the fixed portion 33 is connected to the first scroll 2, and the plurality of movable portions 34 are connected to the fixed portion 33 and are distributed around the fixed portion 33. The plurality of movable portions 34 may correspond to the plurality of exhaust holes 21, respectively, and the movable portions 34 may be configured to open and close the corresponding exhaust holes 21.

[0065] Optionally, the plurality of movable portions 34 may be evenly spaced around the fixed portion 33, so that when the exhaust valve plate 3 is opened, the exhaust valve plate 3 is evenly stressed, thereby avoiding the problem of stress concentration during the use of the exhaust valve plate 3.

[0066] In the aforementioned embodiments, the exhaust assembly 100 in the present invention may be configured as a multi-scroll scroll compression structure.

[0067] The first scroll 2 includes a bottom plate and a plurality of volutes arranged on the surface of the bottom plate. The plurality of volutes are arranged at intervals along the circumference of the bottom plate, and a plurality of compression channels are formed between the plurality of volutes.

[0068] Specifically, the first scroll 2 can be constructed in a disc shape, which includes a bottom plate, and a plurality of scroll teeth are provided on the bottom plate. The plurality of scroll teeth extend in the circumferential direction and are spaced apart and distributed in the circumferential direction. A compression channel is formed between two adjacent scroll teeth. The plurality of scroll teeth form a plurality of compression channels, which can realize multiple channel compression for the gas entering the first scroll 2. In this way, in the process of the first scroll 2 moving horizontally around the predetermined axis, the space in the compression channel where the gas is located is gradually reduced, thereby realizing gas compression.

[0069] In addition, the technical solution of the present application adopts a multi-tooth scroll structure, utilizing the characteristics of multiple teeth. Compared with traditional volumetric compressors, engines and other structures, it has fewer moving parts, simpler assembly, less vibration and noise, and a small overall structural size, which can make the conversion process smooth.

[0070] A plurality of exhaust holes 21 are provided on the bottom plate, each compression channel is connected to at least one exhaust hole 21, and the exhaust valve plate 3 has a plurality of convex parts respectively matched with the plurality of exhaust holes 21, that is, each compression channel can be connected to one exhaust hole 21, or can be connected to a plurality of exhaust holes 21, and in this way, after the gas is compressed, it can be discharged from at least one exhaust hole 21, thereby increasing the exhaust speed on the exhaust side of the first scroll 2. The plurality of convex parts provided on the exhaust valve plate 3 are matched with the plurality of exhaust holes 21 in a one-to-one correspondence, so that the plurality of exhaust holes 21 can be effectively sealed.

[0071] There can be four exhaust holes 21, and each compression channel can be connected to four exhaust holes 21 at the same time, so that the compressed gas in each compression channel is discharged from the four exhaust holes 21, and the exhaust speed is fast, thereby improving the compression performance of the gas in the first scroll 2.

[0072] And, in some embodiments, the first scroll 2 is a fixed scroll or a movable scroll of a compressor.

[0073] Among them, Figure 1As shown, the movable scroll 1 may include a first bottom plate 11 and a plurality of first volutes 12, and the fixed scroll 2 may include a second bottom plate 23 and a plurality of second volutes 24. The first bottom plate 11 and the second bottom plate 23 are distributed in the axial direction, and the first volutes 12 and the second volutes 24 are arranged between the first bottom plate 11 and the second bottom plate 23 and mesh with each other. A plurality of first volutes 12 are distributed circumferentially on the first chassis, and a plurality of second volutes 24 are distributed circumferentially on the second chassis. A compression channel is constructed between two adjacent second volutes 24, and the compression channel extends from the outside to the inside along the spiral direction, and an exhaust hole 21 is arranged at the inner end of the compression channel. During operation, the movable scroll 1 can translate around a predetermined axis, and the first volute 12 translates in the corresponding compression channel, and through the volume change between the first volute 12 and the second volute 24, air is sucked from the surroundings of the fixed scroll 2 and discharged through the exhaust hole 21 to achieve driving fluid.

[0074] For example, Figure 1 As shown, the exhaust assembly 100 in the present invention may have four exhaust holes 21, the exhaust valve plate 3 includes a fixed portion 33 and four movable portions 34, the four movable portions 34 are distributed along the circumference of the fixed portion 33, and the exhaust valve plate 3 is configured as a four-leaf clover structure. Of course, the number of exhaust holes 21 in the exhaust assembly 100 in the present invention may also be two, three, or five, etc.

[0075] In some specific embodiments of the present invention, the exhaust assembly 100 may include a movable scroll 1, a fixed scroll 2, an exhaust valve plate 3, a stopper 4, a rear cover 5, and a cyclone separator valve core. The entire exhaust process is as follows: the fluid (e.g., refrigerant gas) is gradually compressed from the periphery to the compression channel of the movable and fixed scrolls 2 through the rotational motion of the movable scroll 1, and moves radially from the outside to the inside. Then it is discharged through the four exhaust holes 21 on the fixed scroll 2, and the exhaust valve plate 3 is squeezed by the high-pressure gas to form an open state. Under the limiting action of the stopper 4, the exhaust valve plate 3 is warped at a certain angle to discharge the fluid. When the fluid moves to the exhaust chamber 51 formed by the rear cover 5 and the fixed scroll 2, it will enter the cyclone separator through the air inlet 531 on the exhaust channel 52, and under the separation action of the cyclone separator, it will be discharged from the exhaust port of the exhaust channel 52, and the lubricating oil therein will flow to the oil collecting chamber 54.

[0076] Of course, the utility model is not limited to four-tooth vortex stator, but can also be applied to stator vortexes 2 with other numbers of teeth; the position, size and shape of the exhaust hole 21 on the stator vortex 2 can be adjusted to a certain extent, and a new exhaust valve plate 3 and limiter can be designed accordingly; the structural size and installation position of the cyclone separator in the exhaust channel 52 can be modified.

[0077] The utility model further provides a compressor, comprising at least one of the aforementioned exhaust components 100 , wherein a convex portion is provided on the exhaust valve plate 3 , so as to improve the sealing effect of the exhaust valve plate 3 on the exhaust hole 21 .

[0078] The present invention also provides a thermal management system, including the aforementioned exhaust assembly 100. In addition, the present invention also provides a thermal management device, including the aforementioned compressor. And, the present invention also proposes a vehicle, including the aforementioned compressor, or including the aforementioned thermal management system.

[0079] Among them, the thermal management system is applied to the vehicle to realize the heat exchange between various heat exchange systems in the vehicle to achieve different heat exchange requirements, including cooling, heating, heat dissipation, heating and other different modes.
