Description

Technical Field

[0001] The present application belongs to the field of compression technology, and in particular relates to a stationary scroll, a compression mechanism, a compressor and a refrigeration device. Background Art

[0002] At present, the scroll refrigeration compressor assembles a moving scroll vortex (referred to as the movable scroll) and a fixed scroll vortex (referred to as the static scroll) with the same scroll profile parameters and a phase difference of 180° to form a series of crescent spaces; when the movable scroll rotates around the center of the static scroll and makes a non-rotating rotational translation at a certain rotation radius, the crescent space on the outer circle continuously moves toward the center and shrinks, while the unclosed crescent space on the outer side continuously expands; each crescent space periodically expands and shrinks during the rotation of the movable disk, thereby realizing the suction, compression and discharge of gas.

[0003] The existing theory of scroll deformation believes that the volute of the fixed scroll deforms toward the orbiting scroll due to thermal expansion, and the volute of the orbiting scroll deforms toward the fixed scroll due to thermal expansion. Therefore, the method of reducing the height of the volute is usually adopted to improve the axial or radial leakage of gas in the scroll compressor. However, in the actual operation of the scroll compressor, due to different thermodynamic conditions in different parts, refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the volute and the disk body of the movable scroll are deformed toward the fixed scroll. Figure 3 and Figure 4 As shown, the inner end of the volute of the stationary scroll is deformed toward the movable scroll, see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the disk body and the rest of the vortex of the static scroll are deformed away from the orbiting scroll. Since the outer end of the vortex of the static scroll and the vortex of the orbiting scroll are deformed in the same direction, it will cause axial or radial leakage of gas, resulting in power reduction, abnormal exhaust temperature, etc. In addition, it will also cause abnormal wear of the vortex.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] like Fig. 9 , Fig.10 and Fig.11 As shown, in one embodiment of the present application, a static scroll 10 is provided, which is used in conjunction with a movable scroll 20 to play a role in compressing gas. The static scroll 10 includes a static scroll body 11 and a static scroll tooth 12. The static scroll body 11 includes a plate portion 111 and an annular portion 112. The annular portion 112 is arranged around the outer periphery of the plate portion 111 and is connected to the periphery of the plate portion 111. The static scroll tooth 12 is arranged on the plate portion 111 in a spiral shape. The static scroll tooth 12 is located in the annular portion 112. A groove 1111 is arranged on the surface of the plate portion 111 facing away from the static scroll tooth 12. The depth of the groove 1111 is less than the thickness of the plate portion 111. The static scroll tooth 12 has an outer end portion 121 away from the center of the static scroll tooth 12, and the groove 1111 is arranged close to the outer end portion 121 of the static scroll tooth 12. The outer end 121 of the static volute 12 is connected to the inner wall surface of the annular portion 112 . A flange 1121 is provided at the end of the annular portion 112 away from the plate portion 111 . A fixing hole 1122 is provided on the flange 1121 to facilitate connection with external components.

[0046] It should be noted that, see Fig.12As shown, the movable scroll 20 includes a bottom plate 21 and a movable scroll 22. The movable scroll 22 is mounted on the bottom plate 21. The vortex profile parameters of the stationary scroll 12 are the same as those of the movable scroll 22. The movable scroll 20 is eccentric to the stationary scroll 10 and is arranged opposite to it at a difference of 180 degrees, thereby forming a compression mechanism. When the movable scroll 22 rotates and translates with the center of the stationary scroll 12 as the rotation center, the end of the stationary scroll 12 away from the center and the end of the movable scroll 22 away from the center jointly enclose two crescent-shaped spaces. As the movable scroll 22 rotates, the gas in the crescent-shaped space moves toward the center, and the crescents The volume of the crescent-shaped space is constantly shrinking, and the pressure of the gas is constantly and gradually increasing, thereby achieving gas compression; when the two crescent-shaped spaces merge into a central chamber at the center of the static volute 12, and the central chamber is connected to the exhaust hole 1112 of the plate portion 111 at the center of the static volute 12, the compression process ends; when the central chamber disappears, the exhaust process ends; when the end of the static volute 12 away from the center and the end of the movable volute 22 away from the center jointly enclose two crescent-shaped spaces, and as the movable volute 22 rotates, the gas in the crescent-shaped space moves toward the center, a new exhaust process begins to form. After multiple rotations and translations of the movable scroll 20, the process from suction to exhaust is completed.

[0047] Specifically, the static vortex 10 of the embodiment of the present application is combined with Fig.12 As shown, when in use, since the plate portion 111 is provided with a groove 1111 at the outer end portion 121 of the stationary volute 12 away from the center thereof, the groove 1111 weakens the structural strength of the connection between the outer end portion 121 of the stationary volute 12 away from the center thereof and the plate portion 111, then under the action of the exhaust pressure, the deformation amount of the outer end portion 121 of the stationary volute 12 toward the movable scroll 20 increases, thereby compensating for the outer end portion 121 of the stationary volute 12 moving away from the movable scroll 20 under thermal conditions. Deformation, that is, the deformation of the outer end portion 121 of the static volute 12 away from the movable scroll 20 is reduced, so that the contact between the movable volute 22 of the movable scroll 20 and the plate portion 111 and the contact between the static volute 12 and the bottom plate 21 are closer, that is, the movable scroll 20 and the static scroll 10 can be better matched together, and the axial sealing effect of the movable scroll 20 and the static scroll 10 is more significant, which reduces the axial and radial leakage of the gas, improves the power of the compression mechanism using the static scroll 10, and reduces the wear of the volute.

[0048] In this embodiment, the plate portion 111, the annular portion 112 and the static volute 12 are manufactured by one-piece injection molding. This manufacturing method is simple, and the manufactured static volute 12 has good structural strength and can meet the use requirements of high-power compressors; more specifically, the center of the static volute 12, the center of the plate portion 111, the center line of the annular portion 112 and the axis of the exhaust hole 1112 all coincide.

[0049] In this embodiment, see Fig.10 and Fig.11 As shown, the depth of the groove 1111 is less than the thickness of the plate portion 111, and the groove 1111 will not penetrate the plate portion 111, so that the gas in the compression chamber formed by the meshing of the static volute 12 and the movable volute 22 cannot escape from the groove 1111, thereby avoiding affecting the power of the compression mechanism. In addition, it should be noted that the surface of the plate portion 111 facing away from the static volute 12 is provided with a groove 1111, and the groove 1111 and the compression chamber are located on opposite sides of the plate portion 111 and are not connected, so that the meshing of the static volute 12 and the movable volute 22 to compress the gas will not be affected, and the power of the compressor will not be adversely affected, thereby improving the compression efficiency.

[0050] In another embodiment of the present application, see Fig.10 , Fig.13 and Fig.14 As shown, the groove 1111 of the static scroll 10 provided is an arc groove extending in the extension direction of the static scroll tooth 12. Specifically, the arc groove has the same vortex shape as the static scroll tooth 12, so the deformation of the section of the static scroll tooth 12 corresponding to the arc groove toward the movable scroll 20 will increase under the action of the exhaust pressure, so that the end of the static scroll tooth 12 away from the center will deform more away from the movable scroll 20 under thermal conditions, and the deformation of the end of the static scroll tooth 12 away from the center will be smaller away from the movable scroll 20, the movable scroll 20 and the static scroll 10 will cooperate better, and the axial sealing effect of the movable scroll 20 and the static scroll 10 will be more significant, further, the axial and radial leakage of the gas is reduced, and the power of the compression mechanism using the static scroll 10 is improved.

[0051] In another embodiment of the present application, see Fig.10 , Fig.13 and Fig.14 As shown, the arc groove of the static scroll 10 provided extends along the extension direction of the static scroll tooth 12 until it extends to the farthest end of the static scroll tooth 12 away from its center. Under thermal conditions, the farther the part of the static scroll tooth 12 is from its center, the greater its deformation. Then, the arc groove extends along the extension direction of the static scroll tooth 12 until it extends to the farthest end of the static scroll tooth 12 away from its center. Then, under the action of exhaust, the deformation amount of the farthest end of the static scroll tooth 12 away from its center toward the movable scroll 20 will increase, so that the deformation of the farthest end of the entire static scroll tooth 12 away from its center away from the movable scroll 20 is relatively small, so that the deformation of the entire static scroll tooth 12 away from the movable scroll 20 is small, the movable scroll 20 and the static scroll 10 cooperate better, and the axial sealing effect of the movable scroll 20 and the static scroll 10 is more significant.

[0052] In another embodiment of the present application, the static vortex 10 is provided such that the angle of extension corresponding to the farthest end is α 1The arc groove has an angle α at the end away from the farthest end at the corresponding position of the static volute 12. 2 , then the following relationship is satisfied: α 1 -α 2 ≤180°. The difference between the terminal angle and the starting angle of the arc groove corresponding to the static volute 12 is less than 180°, that is, the arc groove should not be extended too long along the static volute 12. If the arc groove is extended too long, under the action of exhaust, the end of the static volute 12 away from the center may be deformed away from the movable scroll 20, thereby failing to reduce the deformation of the end of the static volute 12 away from the center away from the movable scroll 20, thereby aggravating the reduction of the axial and radial leakage of the gas. In specific use, when α 1 is 630°, α 2 When α is 820°, the length of the arc groove is appropriate, which can ensure that the movable scroll 20 and the fixed scroll 10 have a good axial sealing effect; or, when α 1 is 680°, α 2 When the angle is 810°, the length of the arc groove is appropriate, which can ensure that the movable scroll 20 and the fixed scroll 10 have a good axial sealing effect.

[0053] In another embodiment of the present application, see Fig.10 , Fig.13 and Fig.14 As shown, the projection of the outer end portion 121 of the fixed scroll 10 on the plate portion 111 coincides with the projection of the arc-shaped groove on the plate portion 111 .

[0054] Specifically, when the projection area of ​​the outer end portion 121 of the static volute 12 on the plate portion 111 is located within the projection area of ​​the arc groove on the plate portion 111, the arc groove is located directly below the static volute 12, so that the supporting effect of the plate portion 111 on the outer end portion 121 is relatively small. At this time, the outer end portion 121 of the static volute 12 is under the exhaust pressure, and the deformation of the outer end portion 121 of the static volute 12 toward the movable scroll 20 will increase, compensating for the fact that the outer end portion 121 of the static volute 12 will deform the most away from the movable scroll 20 under thermal conditions, and the deformation of the outer end portion 121 of the static volute 12 away from the movable scroll 20 is the smallest, the movable scroll 20 and the static scroll 10 cooperate better, and the axial sealing effect of the movable scroll 20 and the static scroll 10 is the best and most significant.

[0055] Further, when the projection area of ​​the outer end 121 of the static volute 12 on the plate portion 111 intersects with the projection area of ​​the arc groove on the plate portion 111, or the projection area of ​​the arc groove on the plate portion 111 is located in the projection area of ​​the outer end 121 of the static volute 12 on the plate portion 111, the arc groove is located directly below the outer end 121 of the static volute 12, and a portion of the outer end 121 of the static volute 12 corresponding to the plate portion 111 has a smaller thickness and is suspended in the air, so that the support effect of the plate portion 111 on the outer end 121 of the static volute 12 is small, ensuring The static volute 12 can compress the gas stably and reliably; in addition, under the exhaust pressure, the deformation of the outer end portion 121 of the static volute 12 toward the movable scroll 20 will also increase, and the deformation of the outer end portion 121 of the static volute 12 away from the movable scroll 20 under thermal conditions will be compensated, and the deformation of the outer end portion 121 of the static volute 12 away from the movable scroll 20 will also become smaller, which can also improve the coordination effect between the movable scroll 20 and the static scroll 10, and the axial sealing effect of the movable scroll 20 and the static scroll 10 is the best and most significant.

[0056] In other embodiments, the projection area of ​​the outer end portion 121 of the static volute 12 on the plate portion 111 may also completely overlap with the projection area of ​​the arc groove on the plate portion 111. Its specific structure can be selected according to the power of the compression mechanism and the required structural strength, and is not limited here.

[0057] In this embodiment, see Fig.10 , Fig.13 and Fig.14 As shown, the width of the arc groove is greater than the thickness of the outer end portion 121; the more material is removed from the plate portion 111, the weaker the connection strength between the outer end portion 121 of the static volute 12 and the plate portion 111. In this way, when the outer end portion 121 of the static volute 12 is subjected to the exhaust pressure, the greater its deformation is, and the more the thermal deformation of the outer end portion 121 of the static volute 12 is offset, and the deformation of the outer end portion 121 of the static volute 12 away from the movable scroll 20 is smaller, thereby improving the coordination effect between the movable scroll 20 and the static scroll 10, and the axial sealing effect of the movable scroll 20 and the static scroll 10 is the best and most significant.

[0058] In this embodiment, see Fig.10 , Fig.13 and Fig.14As shown, the side wall of the arc groove close to the center of the static vortex tooth 12 is flush with the side wall of the outer end 121 close to the center of the static vortex tooth 12. At the same time, the width of the arc groove is greater than the thickness of the outer end 121 of the static vortex tooth 12. Then the static vortex tooth 12 is located on one side of the arc groove close to the center of the static vortex tooth 12, and the other side of the arc groove extends the static vortex tooth 12 away from the center of the static vortex tooth 12. Due to thermal deformation, the farther the static vortex tooth 12 is from its center, the greater the deformation. In this way, the other side of the arc groove extends the static vortex tooth 12 away from the side of the static vortex tooth 12, which can reduce the structural strength between this side of the static vortex tooth 12 and the plate portion 111, so that it has a greater deformation under the exhaust pressure, thereby effectively offsetting the deformation of the static vortex tooth 12 away from its center, and then effectively reducing the deformation of the outer end 121 of the static vortex tooth 12 away from the movable scroll 20, so that the movable scroll 20 and the static scroll 10 have the best cooperation effect, and the axial sealing effect of the movable scroll 20 and the static scroll 10 is the best.

[0059] In another embodiment of the present application, if the depth of the arc groove of the static scroll 10 is H and the thickness of the plate 111 is h, the following relationship is satisfied: H≤0.6h. The depth H of the arc groove can be 0.1h, 0.2h, 0.3h, 0.4h, 0.5h or 0.6h. The depth of the arc groove is set within the above range. If the depth of the arc groove is too large, the thickness of the plate 111 at the arc groove is too thin, and it is damaged in the compressed gas; if the depth of the arc groove is small, it will not play a role in reducing the structural strength of the connection between the outer end 121 of the static scroll 12 and the plate 111, so that it cannot offset the thermal deformation of the outer end 121 of the static scroll 12, and it is also impossible to reduce the deformation of the outer end 121 of the static scroll 12 away from the movable scroll 20.

[0060] In another embodiment of the present application, a compression mechanism is provided, comprising the above-mentioned fixed scroll 10.

[0061] Specifically, the compression mechanism of the embodiment of the present application adopts the above-mentioned static turbine. Under the action of exhaust pressure, the deformation of the outer end portion 121 of the static vortex tooth 12 toward the movable scroll 20 increases, thereby compensating for the deformation of the outer end portion 121 of the static vortex tooth 12 away from the movable scroll 20 under thermal conditions, that is, the deformation of the outer end portion 121 of the static vortex tooth 12 away from the movable scroll 20 is reduced, so that the movable scroll 20 and the static scroll 10 can be better matched together, so that the axial sealing effect of the movable scroll 20 and the static scroll 10 is more significant, the axial and radial leakage of the gas is reduced, and the power of the compression mechanism using the static scroll 10 is improved.

[0062] In another embodiment of the present application, a compressor is provided, comprising the above-mentioned compression mechanism.

[0063] The compressor of the embodiment of the present application adopts the above-mentioned compression mechanism. Under the action of exhaust pressure, the deformation of the outer end portion 121 of the static scroll tooth 12 toward the movable scroll 20 increases, thereby compensating for the deformation of the outer end portion 121 of the static scroll tooth 12 away from the movable scroll 20 under thermal conditions, that is, the deformation of the outer end portion 121 of the static scroll tooth 12 away from the movable scroll 20 is reduced, so that the movable scroll 20 and the static scroll 10 can be better matched together, so that the axial sealing effect of the movable scroll 20 and the static scroll 10 is more significant, the axial and radial leakage of the gas is reduced, and the power of the compressor to which the compressor is applied is improved.

[0064] In another embodiment of the present application, a refrigeration device is provided, comprising the above-mentioned compressor.

[0065] The refrigeration equipment of the embodiment of the present application adopts the above-mentioned compression mechanism. Under the action of the exhaust pressure, the deformation of the outer end portion 121 of the static scroll tooth 12 toward the movable scroll 20 increases, thereby compensating for the deformation of the outer end portion 121 of the static scroll tooth 12 away from the movable scroll 20 under thermal conditions, that is, the deformation of the outer end portion 121 of the static scroll tooth 12 away from the movable scroll 20 is reduced, so that the movable scroll 20 and the static scroll 10 can be better matched together, so that the axial sealing effect of the movable scroll 20 and the static scroll 10 is more significant, the axial and radial leakage of the gas is reduced, and the power of the refrigeration equipment is improved.

[0066] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
