Electric vehicle controller water cooling device

Abstract

The invention discloses an electric vehicle controller water cooling device which comprises a first concentric-square-shaped frame. A concentric-square-shaped heat dissipation frame is fixedly installed on the inner side of the first concentric-square-shaped frame, heat dissipation through grooves are formed in the top end and the lower end of the concentric-square-shaped heat dissipation frame in a penetrating mode, and a controller body is detachably arranged in an inner cavity of the concentric-square-shaped heat dissipation frame. A water cooling mechanism is arranged at the lower end of the inner side of the first concentric-square-shaped frame. Under the driving of a water pump, in cooperation with the use of a water tank, a liquid inlet pipe, a liquid outlet pipe, a liquid distribution pipe, a snake-shaped bent pipe, a liquid collecting pipe and a backflow pipe, water circulation cooling is achieved, and therefore the cooling effect of the controller body is improved; under the driving of the motor, in cooperation with the use of the rotating disc, the driving column and the second concentric-square-shaped frame, circulating reciprocating motion of the cooling fan is realized, so that air flow at the heat dissipation through grooves in the upper end of the concentric-square-shaped heat dissipation frame can be uniformly driven to flow, heat at the heat dissipation through grooves is taken away by the air flow, and the heat dissipation efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of an electric vehicle controller, in particular to a water cooling device for an electric vehicle controller. Background technique [0002] The electric vehicle controller is the core control device used to control the start, operation, advance and retreat, speed, stop and other electronic devices of the electric vehicle motor. It is like the brain of the electric vehicle and an important part of the electric vehicle. Electric vehicles mainly include electric bicycles, electric two-wheeled motorcycles, electric tricycles, electric three-wheeled motorcycles, electric four-wheeled vehicles, battery cars, etc. Electric vehicle controllers also have different performance and characteristics due to different models.

AI Technical Summary

Problems solved by technology

[0003] The heat dissipation structure of the current electric vehicle controller is only to set the heat sink on the aluminum shell, and does not add other heat dissipation devices for auxiliary heat dissipation, which leads to the general heat dissipation effect of the controller. In addition, the installation of the existing electric vehicle controller The stability is poor, which affects the subsequent normal use of the controller. Therefore, we propose a water cooling device for electric vehicle controllers to solve the above problems
