Description

Technical Field

[0001] This application relates to the field of compressor heat dissipation, and in particular to a motor and compressor for use in compressors. Background Technology

[0002] In compressors, the motor is one of the main heat sources. Currently, compressor motor cooling relies solely on the refrigerant inside the casing; the refrigerant's flow carries the heat generated by the motor (through the exhaust pipe) to the outside of the compressor casing. However, experimental results show that when the compressor operates under high speed and high load conditions, the motor still generates significant heat, indicating poor refrigerant cooling performance. Utility Model Content

[0003] In view of this, the purpose of this application is to provide a motor and a compressor for a compressor, so as to solve the problem that the existing method of cooling the motor inside the compressor by means of refrigerant has poor heat dissipation effect.

[0004] In accordance with the above objectives, a first aspect of this utility model provides a motor for a compressor, including a stator, wherein a plurality of annular grooves are formed on the outer surface of the stator, each annular groove is fitted with a corresponding heat dissipation aluminum ring, and the heat dissipation aluminum ring forms a heat dissipation portion.

[0005] Preferably, the annular groove is formed on the outer surface of the stator core.

[0006] Preferably, the annular groove includes a first annular groove and a second annular groove, and the first annular groove and the second annular groove are spaced apart along the axial direction of the stator.

[0007] Preferably, when the heat dissipation aluminum ring is assembled with the first annular groove and the second annular groove, the axis of the heat dissipation aluminum ring is collinear with the axis of the stator.

[0008] Preferably, the heat dissipation aluminum ring is formed into a main body, which has an unfolded state and a closed state.

[0009] Preferably, when the main body is in the unfolded state, the main body is formed into an elongated structure, and a protrusion is formed at the first end of the main body in the extension direction, and a recess corresponding to the protrusion is formed at the second end of the main body in the extension direction.

[0010] Preferably, the protrusion and the recess can be engaged to form the main body in the closed state; when the main body is in the closed state, the main body forms a ring structure.

[0011] Preferably, the outer side wall of the main body is provided with a plurality of heat dissipation fins to form the heat dissipation part.

[0012] Preferably, the plurality of heat dissipation fins are evenly distributed at intervals.

[0013] According to a second aspect of the present invention, a compressor is provided, wherein the compressor includes a motor for the compressor as described above.

[0014] According to the present invention, a motor and compressor for a compressor are provided with multiple annular grooves on the outer surface of the motor stator, and a corresponding heat-dissipating aluminum ring is provided in each annular groove. The heat-dissipating aluminum ring itself can dissipate heat from the motor (metal has thermal conductivity), and the effective heat dissipation area of ​​the heat-dissipating aluminum ring is larger than that of existing motors, resulting in better heat dissipation. Furthermore, the heat-dissipating aluminum ring also forms a heat dissipation section, thereby enhancing the heat dissipation effect. In this way, the motor can dissipate heat in a timely manner when the compressor is running under high speed and high load conditions. In addition, the heat-dissipating aluminum ring is assembled with the motor stator through the annular grooves without affecting the overall size of the motor, that is, it will not interfere with the assembly of the motor and the compressor, thus eliminating the need for secondary design of the compressor housing and saving design costs.

[0024] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between.

Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible, as will be apparent upon understanding the disclosure of this application.

[0031] According to a first aspect of the present invention, a motor for a compressor is provided, such as... Figures 1 to 4 As shown, the motor for the compressor in this embodiment includes a stator 1 (the stator 1 itself is one of the inherent components of the motor). The outer surface of the stator 1 has multiple annular grooves. Effective heat dissipation of the motor can be achieved by assembling a corresponding heat-dissipating aluminum ring 2 in each annular groove. The specific structure and connection relationships of the above-mentioned parts of the motor for the compressor according to this utility model will be described in detail below.

[0032] Specifically, in this embodiment, an annular groove is formed on the outer surface of the stator 1's core. Further, as... Figure 1As shown, the annular grooves in this embodiment include a first annular groove 11 and a second annular groove 12, which are spaced apart along the axial direction of the stator 1. It should be noted that the specific positions and specifications of the first annular groove 11 and the second annular groove 12 are not fixed. Furthermore, the number of annular grooves is not limited to these; for example, three annular grooves can also be provided. In other words, the specific number, specifications, and placement of the annular grooves should be comprehensively considered, as long as they can meet the heat dissipation requirements of the motor under various operating conditions.

[0033] In this embodiment, corresponding heat dissipation aluminum rings 2 are respectively assembled in the first annular groove 11 and the second annular groove 12. The heat dissipation aluminum rings 2 themselves have good thermal conductivity (based on the thermal conductivity characteristics of aluminum material itself). When they are assembled with the first annular groove 11 and the second annular groove 12, they can achieve a good heat dissipation effect on the stator 1 (and the motor). Correspondingly, when the heat dissipation aluminum rings 2 are assembled with the first annular groove 11 and the second annular groove 12, the axis of the heat dissipation aluminum rings 2 is collinear with the axis of the stator 1.

[0034] Specifically, such as Figures 2 to 4 As shown, the heat dissipation aluminum ring 2 has a main body 21, which has an unfolded state and a closed state. When the main body 21 is in the unfolded state, it forms an elongated structure, and a protrusion 211 is formed at the first end of the main body 21 extending in the direction of extension, and a recess 212 corresponding to the protrusion 211 is formed at the second end of the main body 21 extending in the direction of extension. The protrusion 211 and the recess 212 can be engaged to form a closed state; when the main body 21 is in the closed state, it forms a ring-shaped structure.

[0035] It should be noted that the specific structure of the protrusion 211 and the recess 212 is not limited. Achieving a snap-fit ​​connection through a convex-concave fit is a conventional technique in the mechanical field, and therefore will not be elaborated further. Based on this snap-fit ​​structure, the heat dissipation aluminum ring 2 and the stator 1 are actually detachably connected, facilitating the installation or removal of the heat dissipation aluminum ring 2. Specifically, during the assembly of the motor and compressor 3, the heat dissipation aluminum ring 2 can be first assembled to correspond with the stator 1 (that is, the unfolded main body 21 is placed in the corresponding annular groove, and then the main body 21 is bent and fastened to make the main body 21 closed), and then the motor equipped with the heat dissipation aluminum ring 2 is assembled to the compressor 3.

[0036] In addition, such as Figure 4 As shown, the snap-fit ​​structure of the main body 21 can ensure the stability of the connection between the heat dissipation aluminum ring 2 and the stator 1. Under the limiting of the compressor housing 3, the heat dissipation aluminum ring 2 can be further limited to improve the stability of the connection between the heat dissipation aluminum ring 2 and the stator 1.

[0037] Furthermore, such as Figure 2 As shown, the outer wall of the main body 21 is provided with multiple heat dissipation fins 22 to form a heat dissipation section. These heat dissipation fins 22 are formed into cuboid sheet structures (the heat dissipation fins 22 themselves are existing components, and their heat dissipation principle will not be elaborated further). These heat dissipation fins 22 can be integrally formed with the main body 21 through injection molding or other methods. Furthermore, to ensure uniform heat dissipation from the motor, the multiple heat dissipation fins 22 should be evenly distributed. The arrangement of the heat dissipation fins 22 further improves the heat dissipation effect on the motor. It should be noted that there are no specific limitations on the number, specifications, and spacing of the heat dissipation fins 22; these should be determined comprehensively based on actual conditions, such as the specifications of the main body 21, as long as the aforementioned technical effects can be achieved.

[0038] According to the present invention, a motor for a compressor has multiple annular grooves on the outer surface of the motor stator 1, and a corresponding heat dissipation aluminum ring 2 is provided in each annular groove. The heat dissipation aluminum ring 2 itself can dissipate heat from the motor (metal has thermal conductivity), and the effective heat dissipation area of ​​the heat dissipation aluminum ring 2 is larger than that of existing motors, resulting in better heat dissipation. Furthermore, the heat dissipation aluminum ring 2 also has a heat dissipation section, thereby enhancing the heat dissipation effect. In this way, the motor can dissipate heat in a timely manner when the compressor 3 is running under high speed and high load conditions. In addition, the heat dissipation aluminum ring 2 is assembled with the motor stator 1 through the annular grooves without affecting the overall size of the motor, that is, it will not interfere with the assembly of the motor and the compressor 3, thus eliminating the need for secondary design of the compressor 3 housing and saving design costs.

[0039] According to a second aspect of the present invention, a compressor 3 is provided, the compressor 3 including a motor for the compressor 3 as described above.

[0040] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto.

Such modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be covered within the protection scope of this application.
