Abstract

The invention discloses an MOS transistor radiating structure and an electric vehicle controller. The MOS transistor radiating structure comprises a radiating shell, a PCB, a snap spring elastic sheet and an insulating layer, wherein the radiating shell adopts a hollow structure; a polygonal cavity formed by multiple mounting planes is formed in the radiating shell; the PCB is arranged in the cavity of the radiating shell; the PCB is set to be polygonal for being matched with the cavity of the radiating shell; at least an MOS transistor is arranged on the edge of each side of the PCB; the snap spring elastic sheet is arranged on the inner sides of the MOS transistors and is set to be a polygonal structure for being matched with a region encircled by all the MOS transistors, wherein an opening is formed in the polygonal structure of the snap spring elastic sheet; multiple elastic sides are arranged on each side of the snap spring elastic sheet at intervals; and the insulating layer is arranged between the MOS transistors and the mounting planes. The MOS transistor radiating structure and the electric vehicle controller have the advantages of compact structure, small volume, convenient installation, high radiating efficiency and the like.

Description

technical field [0001] The invention belongs to the heat dissipation technology of an electric vehicle controller, and in particular relates to a MOS tube heat dissipation structure for an electric vehicle and an electric vehicle controller. Background technique [0002] China is currently a developing country with a large population. With the improvement of people's production and living standards, the promotion of clean energy and the enhancement of environmental protection awareness, electric vehicles are becoming more and more popular among the people.
