Abstract

The present application discloses an electric industrial vehicle controller including a heat dissipation device. Include: control body, a controller circuit board arranged in the controller main bodyand a heat dissipation boss fixedly supporting the circuit board with the controller, The heat dissipation boss comprises a heat dissipation base arranged at the bottom of the controller main body anda vertical part connected with the heat dissipation base, and the top of the vertical part is connected with the bottom of the controller circuit board through an insulating heat conductive silicon adhesive tape for conducting heat. By means of setting heat dissipation boss, heat in the concentrated area of the power device of the controller circuit board is transmitted out through the aluminum plate through the heat dissipation boss through the insulating heat conductive silicon adhesive tape, The heat is then transferred to the peripheral periphery of the controller through the heat dissipation boss, thereby realizing the technical effect of high heat dissipation of the controller and solving the technical problem of poor heat dissipation of the controller in the related art.

Description

Technical field [0001] This application relates to the field of electric vehicle controllers, and in particular to an electric industrial vehicle controller containing a heat dissipation device. Background technique [0002] The motor controller of electric industrial vehicles can achieve high-efficiency control of AC asynchronous motors, and is widely used in low-speed vehicles that use motors as driving devices, such as patrol cars, passenger cars, and logistics vehicles. [0003] The inventor found that the existing controllers in the field of electric industrial vehicles need to drive many inductive loads, such as solenoid valve contactors, electromagnetic brakes, etc. The drive components are placed on the control board to reduce heat concentration and reduce The overall heat generation, this structural design has a poor heat dissipation effect, resulting in poor overall system reliability. [0004] Therefore, there is an urgent need for an electric industrial vehicle controlle...
