[0037] 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] Hereinafter, with reference to the accompanying drawings, a compressor housing 1 according to an embodiment of the present invention will be described.

[0039] like Figure 1-Figure 4 As shown, the shell 1 of the compressor according to the embodiment of the utility model includes: a shell body 11 and a plurality of bosses 12, the shell body 11 is provided with a mounting cavity 111, the plurality of bosses 12 are spaced apart on the inner circumferential wall of the mounting cavity 111 and protrude inwardly, an axial extension direction of each boss 12 and an extension direction of the central axis W of the shell body 11 have an angle, and guide grooves 13 for guiding the flow of refrigerant are defined between adjacent bosses 12.

[0040] As a result, the extension direction of the guide groove 13 can correspond to the flow path of the refrigerant, which improves the guiding effect of the guide groove 13 on the refrigerant, helps to reduce flow resistance and noise, and can extend the flow path, thereby improving the cooling effect of the refrigerant.

[0041] First, if Figure 1-Figure 2 As shown, the compressor 100 includes a housing 1, a stator assembly 2 and a rotor assembly 3, wherein the stator assembly 2 is mounted on the outer side of the rotor assembly 3. The housing 1 includes a housing body 11, which is cylindrical in shape, and a mounting cavity 111 with one end open is provided in the housing body 11, and the stator assembly 2 is matched with the mounting cavity 111 so that the stator assembly 2 and the rotor assembly 3 can be installed in the mounting cavity 111 together.

[0042] The housing 1 further includes a plurality of bosses 12, which are arranged at the inner peripheral wall of the mounting cavity 111 and spaced apart along the circumference of the housing body 11. The bosses 12 are arranged to protrude inwardly along the radial direction of the housing body 11, and the plurality of bosses 12 are respectively supported at the outer peripheral wall of the stator assembly 2 to be limitedly matched with the stator assembly 2. A guide groove 13 is provided between any two adjacent bosses 12, and the housing 1 and the stator assembly 2 can define a guide channel at the guide groove 13, and the guide channel is used to guide the flow of the refrigerant.

[0043] Specifically, when the compressor 100 is running, the refrigerant can flow into the compressor 100, and the refrigerant will rotate and flow into the guide channel in the compressor 100. When flowing through the guide channel, the refrigerant can cool the stator assembly 2 and the housing 1. Then, the refrigerant can flow to the stator assembly 2 and the rotor assembly 3 and be compressed.

[0044] Furthermore, if Figure 2 and Figure 3 As shown, an angle can be set between the axial extension direction of each boss 12 and the extension direction of the central axis W of the shell body 11, so that an angle is formed between the extension direction of the guide groove 13 and the extension direction of the central axis W of the shell body 11, so that the guide channel can correspond to the flow path of the refrigerant. In this way, the guiding effect of the guide groove 13 on the refrigerant can be improved, the flow stability of the refrigerant can be improved, the flow resistance can be reduced, and noise can be eliminated.

[0045] In addition, compared with the solution in which the extension direction of the guide groove 13 is parallel to the extension direction of the central axis W of the shell body 11, the present application can extend the flow path, improve the cooling effect of the refrigerant on the shell 1 and the stator assembly 2, and can also increase the contact area between the boss 12 and the stator assembly 2, so that the force on the stator assembly 2 is more uniform and the transmittable torque is greater.

[0046] According to the compressor shell 1 of the embodiment of the utility model, an angle is set between the axial extension direction of each boss 12 and the extension direction of the central axis W of the shell body 11, so that the extension direction of the guide groove 13 can correspond to the flow path of the refrigerant, thereby improving the guiding effect of the guide groove 13 on the refrigerant, which is beneficial to reducing flow resistance and noise, and can extend the flow path to improve the cooling effect of the refrigerant.

[0047] In some embodiments of the present invention, Figure 2 As shown, a plurality of bosses 12 may be arranged evenly spaced apart along the circumference of the mounting cavity 111. Through the above arrangement, the bosses 12 can more stably support the stator assembly 2, improve the stability of the stator assembly 2, and make the plurality of guide grooves 13 evenly distributed, which is conducive to improving temperature uniformity.

[0048] Of course, the present application is not limited to this, and the bosses 12 may also be divided into multiple groups, and the multiple groups of bosses 12 are evenly spaced apart along the circumference of the mounting cavity 111; or, the multiple bosses 12 may be divided into two groups, and the two groups of bosses 12 are radially symmetrically arranged relative to the shell body 11; or, the multiple bosses 12 may be arranged to be unevenly spaced apart along the circumference of the mounting cavity 111. For example, in an area where the temperature of the compressor 100 is higher, the distance between two adjacent bosses 12 may be larger, which will not be repeated here.

[0049] In some embodiments of the present invention, the number of bosses 12 is n, and on the same cross section, the angle occupied by the width of the guide groove 13 in the circumferential direction of the shell 1 is A1, satisfying: 0.6*360° / n≤A1≤0.8*360° / n.

[0050] For example, refer to Figure 2 and Figure 4 As shown, the number of bosses 12 can be set to n, and the number of guide grooves 13 can be set to n accordingly. On the same cross section, the angle occupied by the width of the guide groove 13 in the circumferential direction of the housing 1 can be set to A1, satisfying: 0.6*360° / n≤A1≤0.8*360° / n.

[0051] Specifically, the angle A1 occupied by the width of the guide groove 13 in the circumferential direction of the shell 1 can be set to 0.65*360° / n; or, the angle A1 occupied by the width of the guide groove 13 in the circumferential direction of the shell 1 can be set to 0.7*360° / n; or, the angle A1 occupied by the width of the guide groove 13 in the circumferential direction of the shell 1 can be set to 0.75*360° / n, and this application does not impose any restrictions on this. In this way, it can be ensured that the guide groove 13 has a sufficient width, which is conducive to increasing the flow rate of the refrigerant and ensuring the cooling effect of the refrigerant.

[0052] In some embodiments of the present invention, the hydraulic diameter of the guide groove 13 can be L, satisfying: 10mm≤L≤15mm; wherein the hydraulic diameter is determined based on the ratio of the cross-sectional area of ​​the guide groove 13 to the cross-sectional circumference of the guide groove 13.

[0053] For example, the hydraulic diameter L of the guide groove 13 can be set to 11 mm; or, the hydraulic diameter L of the guide groove 13 can be set to 12 mm; or, the hydraulic diameter L of the guide groove 13 can be set to 13 mm; or, the hydraulic diameter L of the guide groove 13 can be set to 14 mm, and the present application does not impose any restrictions on this.

[0054] It can be understood that by limiting the hydraulic diameter of the guide groove 13 to the above range, the flow rate of the refrigerant can be guaranteed, thereby improving the design rationality of the shell 1.

[0055] More preferably, the housing 1 may be arranged to satisfy: 10 mm ≤ L ≤ 12 mm.

[0056] In some embodiments of the present invention, Figure 4 As shown, the inner diameter of the boss 12 can be set to d0, and the inner diameter of the shell body 11 can be set to D0, satisfying: S=A1 / 360°.

[0057] Through the above settings, the size of the guide groove 13 can be limited, thereby ensuring that the guide groove 13 has a suitable depth and width, which is beneficial to improving the flow stability of the refrigerant in the guide groove 13, and can ensure the flow rate of the refrigerant, thereby improving the design rationality of the shell 1.

[0058] In some embodiments of the present invention, Figure 4 As shown, the inner diameter of the boss 12 can be set to d0, and the inner diameter of the shell body 11 can be set to D0, satisfying: 1.1d0≤D0≤1.2d0. For example, the inner diameter D0 of the shell body 11 can be set to 1.12 times the inner diameter d0 of the boss 12; or, the inner diameter D0 of the shell body 11 can be set to 1.15 times the inner diameter d0 of the boss 12; or, the inner diameter D0 of the shell body 11 can be set to 1.18 times the inner diameter d0 of the boss 12, and this application does not limit this.

[0059] Through the above arrangement, the boss 12 has a larger protruding size, so that the guide groove 13 has a sufficient depth, thereby ensuring the guide effect of the guide groove 13 on the refrigerant and improving the design rationality of the shell 1.

[0060] More preferably, the housing 1 may be arranged to satisfy: 1.15d0≤D0≤1.2d0.

[0061] Furthermore, if Figure 4 As shown, the outer diameter of the shell body 11 can be set to D1, satisfying: 1.2d0≤D1≤1.3d0. For example, the outer diameter D1 of the shell body 11 can be set to 1.22 times the inner diameter d0 of the boss 12; or, the outer diameter D1 of the shell body 11 can be set to 1.25 times the inner diameter d0 of the boss 12; or, the outer diameter D1 of the shell body 11 can be set to 1.28 times the inner diameter d0 of the boss 12, and this application does not limit this.

[0062] Through the above arrangement, the structural strength of the shell body 11 can be ensured, and the excessive thickness of the shell body 11 that causes the shell body 1 to be too heavy can be avoided.

[0063] In some embodiments of the present invention, the number of bosses 12 is n, and on the same cross section, the angle occupied by the width of the boss 12 in the circumferential direction of the shell 1 is A2, satisfying: 0.1*360° / n≤A2≤0.4*360° / n.

[0064] For example, refer to Figure 4 As shown, the number of bosses 12 can be set to n. On the same cross section, the angle occupied by the width of the boss 12 in the circumferential direction of the housing 1 can be set to A2, satisfying: 0.1*360° / n≤A2≤0.4*360° / n.

[0065] Specifically, the angle A2 occupied by the width of the boss 12 in the circumferential direction of the shell 1 can be taken as 0.15*360° / n; or, the angle A2 occupied by the width of the boss 1 in the circumferential direction of the shell 1 can be taken as 0.2*360° / n; or, the angle A2 occupied by the width of the boss 1 in the circumferential direction of the shell 1 can be taken as 0.3*360° / n, and the present application does not impose any restrictions on this.

[0066] Through the above arrangement, the boss 12 can have a sufficient width to increase the contact area between the housing 1 and the stator assembly 2, improve the installation stability of the stator assembly 2, and help ensure the structural strength of the boss 12, thereby improving the overall reliability of the housing 1.

[0067] In some embodiments of the present invention, Figure 2 As shown, in the circumferential direction of the housing 1, the angle occupied by the two axial ends of the boss 12 can be set to A3, satisfying: 1.5A2≤A3≤6A2. For example, the angle A3 occupied by the two axial ends of the boss 12 can be set to be twice the angle A2 occupied by the width of the boss 12 in the circumferential direction of the housing 1; or, the angle A3 occupied by the two axial ends of the boss 12 can be set to be three times the angle A2 occupied by the width of the boss 12 in the circumferential direction of the housing 1; or, the angle A3 occupied by the two axial ends of the boss 12 can be set to be four times the angle A2 occupied by the width of the boss 12 in the circumferential direction of the housing 1.

[0068] Through the above arrangement, the coverage angle of the boss 12 can be ensured, the contact area between the boss 12 and the stator assembly 2 can be increased, the force on the stator assembly 2 can be more uniform, the transmittable torque can be larger, and the guide effect of the guide groove 13 can be ensured, thereby improving the design rationality of the shell 1.

[0069] In some embodiments of the present invention, Figure 4 As shown, the angle between the axial extension direction of the boss 12 and the extension direction of the central axis W of the shell body 11 can be set to α1, satisfying: 0°<α1≤30°. For example, the angle α1 between the axial extension direction of the boss 12 and the extension direction of the central axis W of the shell body 11 can be set to 5°, 10°, 15°, 20°, 25°, etc., and this application does not limit this.

[0070] Through the above arrangement, while ensuring the guiding effect of the boss 12 , the difficulty of processing the boss 12 can be reduced, which is beneficial to improving the design rationality of the housing 1 .

[0071] More preferably, the housing 1 may be arranged to satisfy: 10°<α1≤20°.

[0072] Of course, the present application is not limited thereto, and the angle α1 between the axial extension direction of the boss 12 and the extension direction of the central axis W of the shell body 11 can be set to 50°, 60°, 70°, 80°, etc., so as to construct the boss 12 into a spiral shape. In this way, the flow path can be further extended and the cooling effect of the refrigerant can be improved.

[0073] In some embodiments of the present invention, Figure 3 As shown, a chamfered portion 121 may be provided between adjacent side walls of the boss 12. Through the above arrangement, during the assembly process of the compressor 100, the boss 12 may be prevented from scratching the stator assembly 2 or the operator, which is beneficial to improving the design rationality of the housing 1.
