Description

Technical Field

[0001] This utility model relates to the field of motor winding technology, specifically a heat dissipation structure for stator winding coils. Background Technology

[0002] Stator windings can be classified into two types—display-pole and concealed-pole—based on the relationship between the number of magnetic poles in the motor and the actual number of magnetic poles formed by the winding distribution. Existing stator winding carrier structures mostly employ integrated metal structures, resulting in thick walls, poor heat dissipation, and heavy weight. Therefore, this paper proposes a stator winding coil heat dissipation structure to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a heat dissipation structure for stator winding coils in order to solve the above-mentioned problems.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a stator winding coil heat dissipation structure, comprising a porous heat dissipation winding tube, wherein the inner and outer surfaces of the porous heat dissipation winding tube are respectively provided with an inner groove and an outer groove at equal intervals, and the outer groove is located at the middle position between the outer sides of two adjacent inner grooves; both ends of the porous heat dissipation winding tube are provided with ring blocks; the outer part of the inner groove is welded together with the corresponding connecting groove; a corresponding connecting block is embedded in the outer groove; and the two ring blocks are connected to each other by a breathable protective cover.

[0005] Preferably, the inner ring wall of the ring block is provided with multiple connecting grooves at equal intervals, and a connecting block is formed between two adjacent connecting grooves.

[0006] Preferably, both the porous heat dissipation winding tube and the ring block are made of high-temperature resistant insulating materials.

[0007] Preferably, the wall thickness of the porous heat dissipation winding tube is 1cm to 2cm.

[0008] Compared with existing technologies, the difference lies in the fact that by utilizing the inner and outer annular groove groups distributed on the porous heat dissipation winding tube, and combining them with the micropore structures on the porous heat dissipation winding tube, a thin and light stator winding coil heat dissipation structure can be formed, solving the problem of slow heat dissipation caused by excessively thick structures.
