Description

Technical Field

[0001] The present invention relates to the technical field of electrical machine components, and particularly to a wind shield ring and an electrical machine of an electrical machine. Background Art

[0002] During the operation of an electrical machine, a large amount of heat is generated and needs to be discharged in time through a heat dissipation system to avoid high temperature affecting performance or lifespan. Most of the wind shield rings of traditional electrical machines adopt a simple annular structure and are only used for fixing a fan or guiding air flow, and there are the following problems:

[0003] 1. Low air flow guiding efficiency: The traditional wind shield ring lacks an optimized air flow channel design, resulting in uneven distribution of heat dissipation air flow and local overheating.

[0004] 2. High noise: Eddy currents are easily generated when the air flow collides with the inner wall of the wind shield ring, increasing the operating noise.

[0005] 3. Complicated installation: Some wind shield rings need to be fixed by bolts, which is inconvenient for disassembly and maintenance.

[0006] Therefore, there is an urgent need to propose a wind shield ring design with a simple structure, high heat dissipation efficiency and low noise. Summary of the Invention

[0007] In view of the above problems, the present invention provides a wind shield ring and an electrical machine of an electrical machine, which improve the heat dissipation efficiency, reduce noise and simplify the installation steps by optimizing the air flow guiding structure.

[0008] The technical solution of the present invention is as follows:

[0009] A wind shield ring of an electrical machine includes an annular main body, and a plurality of arc-shaped guiding vanes are evenly distributed on the inner circumference of the annular main body; a double-layer noise reduction structure is further arranged on the inner side surface of the annular main body, and the double-layer noise reduction structure is composed of an inner shell and an outer shell, and a sound-absorbing material is filled between the inner shell and the outer shell or a honeycomb-shaped sound-absorbing structure is arranged; a quick installation component is arranged at one end of the annular main body connected to the machine shell.

[0010] In a further technical solution, the guiding vanes are inclined relative to the inner side surface of the annular main body, and the inclination angle is 15° - 30°.

[0011] In a further technical solution, the quick installation component is an elastic buckle or a magnetic connecting piece, and is used for directly clamping or adsorbing and fixing with the motor housing.

[0012] In a further technical solution, heat dissipation fins are arranged on the outer side of the annular main body.

[0013] In a further technical solution, the annular main body is made of aluminum alloy, nylon reinforced plastic or polycarbonate, and an anti-corrosion coating is arranged on the outer surface.

[0014] In a further technical solution, a sealing rubber ring is provided on the contact surface between the annular body and the motor housing.

[0015] The present invention also provides a motor equipped with the above-mentioned wind shield ring.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention uses arc-shaped guide vanes to direct the airflow, which can increase the wind speed in the heat dissipation area by more than 30% and enhance the heat dissipation effect;

[0018] 2. The present invention adopts a double-layer noise reduction structure, which can effectively reduce the airflow friction noise;

[0019] 3. The present invention adopts elastic buckles or magnetic connections to achieve tool-free disassembly and assembly, with high maintenance efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
