Title:
FILM CAPACITOR MOUNTING AND HEAT-DISSIPATING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/206308
Kind Code:
A1
Abstract:
Disclosed in the utility model is a film capacitor mounting and heat-dissipating structure, comprising a controller main housing. The bottom of the controller main housing is provided with a film capacitor mounting recess. A film capacitor is placed in the film capacitor mounting recess. The top of the film capacitor is provided with a water-cooling plate fixedly connected to the controller main housing. The water-cooling plate compresses the film capacitor. A thermal conductive silicone pad is provided between the water-cooling plate and the film capacitor. The bottom and sides of the film capacitor are fixed to the film capacitor mounting recess by injecting a potting adhesive. In the present solution, the film capacitor is directly potted in the controller main housing by means of the potting adhesive, and the top water-cooling plate further compresses the capacitor to ensure the reliability of fixation; a thermal conductive silicone pad is provided between the film capacitor and the water-cooling plate to increase the coefficient of thermal conductivity; in addition, the gaps between the remaining surfaces of the capacitor and the housing are filled with the potting adhesive. The whole solution achieves higher heat dissipation efficiency, has a better heat dissipation effect on the capacitor, and can effectively reduce the working temperature of the film capacitor and improve the life of the capacitor.
