Title:
COMPOSITE INTEGRATED PHASE-CHANGE TOOTHED-BELT HEAT DISSIPATION STRUCTURE FOR ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2024/087562
Kind Code:
A1
Abstract:
The present utility model relates to a composite integrated phase-change toothed-belt heat dissipation structure for an electric motor. The structure comprises an overhanging winding and an electric-motor housing, wherein at least two toothed belts are arranged between the overhanging winding and the electric-motor housing, the at least two toothed belts are sequentially arranged in an axial direction of the overhanging winding, each toothed belt comprises tooth roots and tooth tops, and the tooth roots of any toothed belt are arranged corresponding to the tooth tops of an adjacent toothed belt. Each circumferential part of the overhanging winding is divided into at least two regions in the axial direction, and among the at least two regions, at least one region is in contact with the tooth roots of the toothed belt, such that the situation of the whole axial region of the overhanging winding between two adjacent tooth roots not being in contact with the toothed belt is avoided. The overhanging winding is subdivided into more small regions in the axial direction, and the contact between the overhanging winding and the toothed belt is increased on the small regions, such that each circumferential part of the overhanging winding can be in contact with the toothed belt for heat transfer, the overall heat dissipation of the overhanging winding is more uniform, the performance of the electric motor is improved, and the service life of the electric motor is prolonged.
