Title:
ROUND-WIRE MOTOR HEAT DISSIPATION STRUCTURE BASED ON ARC-SHAPED BENT PHASE CHANGE HEAT PIPES
Document Type and Number:
WIPO Patent Application WO/2024/087554
Kind Code:
A1
Abstract:
A round-wire motor heat dissipation structure based on arc-shaped bent phase change heat pipes, comprising a casing (1), phase change heat pipes (2) and overhanging windings (3), the overhanging windings (3) being arranged in the middle part of the casing (1), a heat dissipation component being arranged between the overhanging windings (3) and the inner wall of the casing (1), and the heat dissipation component comprising a plurality of the arc-shaped phase change heat pipes (2). The plurality of bent phase change heat pipes (2) are used as the heat dissipation component to fill a space between the casing (1) and the overhanging windings (3), so as to form additional heat dissipation passages between the overhanging windings (3) and the phase change heat pipes (2) which are in contact with the overhanging windings, thereby transferring heat to the casing (1) by means of the heat dissipation component and dissipating same into air. Since the heat dissipation component consisting of the bent phase change heat pipes (2) is additionally provided in the structure, the interior of a round-wire motor is more compact, thus avoiding the problem of poor heat conduction performance caused by air.
