Novel motor controller heat dissipation system

Abstract

The invention discloses a novel motor controller heat dissipation system which comprises a seal cavity, liquid phase change media are arranged inside the cavity, the cavity wall comprises at least one micro groove wall and a heat dissipation wall, and the outer surface of the micro groove wall is suitable for being tightly attached to a heating element. The inner surface of the micro groove wall is provided with a micro groove, the heat dissipation wall is provided with a cooling device, a micro groove protection baffle arranged inside the seal cavity is close to the micro groove wall, and the upper end and the lower end of the micro groove protection baffle are respectively provided with a channel used for passing through of the phase change media. According to the fact that the micro groove protection baffle is arranged inside the seal cavity, formation of a micro groove thin liquid film is protected, steaming and heat dissipation can be also achieved during movement of an automobile, and heat dissipation efficiency of a motor controller is improved. The whole system is simple in structure, is relatively small in size under the same heat dissipation efficiency, and high in heat dissipation maximum.

Description

technical field [0001] The invention relates to the field of radiators, in particular to a heat dissipation system for electric vehicle controllers. Background technique [0002] With the progress of society, people's demand for energy is increasing, while non-renewable resources such as oil on the earth are decreasing sharply, which seriously restricts the long-term sustainable development of human civilization. Therefore, people have begun to actively explore new renewable resources. resources to replace traditional energy sources. It is the urgent need for this development that various new energy vehicles have emerged as the times require, among which pure electric vehicles have been greatly developed in recent decades. [0003] The motor control system is one of the key technologies of electric vehicles. As the core component of electric vehicles, the motor controller directly affects the quality of electric vehicles. Most of the heating of the control system is cause...

AI Technical Summary

Problems solved by technology

Due to the micro-groove structure, the heat dissipation efficiency of this radiator is greatly improved. However, this micro-groove phase-change radiator is currently mainly used for heat dissipation of fixed electronic components, and the electric vehicle is always in the process of moving. Shaking state, this kind of shaking will cause the medium to splash violently in the sealed cavity, and the splashed liquid hits the wall of the microgroove, destroying the evaporation of the thin liquid film layer on the wall of the microgroove, thereby affecting the efficiency of heat dissipation

Therefore, this efficient micro-groove group heat dissipation technology cannot be applied to the heat dissipation of moving objects such as electric vehicles.
