Electric vehicle controller having great heat radiation performance

Abstract

The invention discloses an electric vehicle controller having great heat radiation performance. The electric vehicle controller comprises a heat radiation box. An installing base is fixedly installedin the middle part of the bottom part of the heat radiation box. A top cover is flexibly connected on the top part of the heat radiation box. The left side of the heat radiation box is provided with an air inlet. The right side of the heat radiation box is provided whit an air outlet. The air inlet is flexibly provided with a pair of fixed frames. The middle part of the fixed frames is fixedly provided with air blades. An air guide ventilator is fixedly connected on one side of the fixed frames. The heat radiation box is enabled to have the heat radiation and cooling performance through arrangement of the heat radiation box, the air blades, the air guide ventilator, the conical bending pipeline, the conical air guide port and the water absorbing sponge, and the heat generated by the controller body can be rapidly transferred out so that heat radiation and cooling of the controller body can be realized, the driving speed of the electric vehicle can be maintained, the service life of thecontroller can be prolonged and the probability of burnout of the controller and fire can be reduced.

[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; At present, 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. For example, for small battery cars, the electric vehicle controller is generally installed under the seat cushion of the rear row, the installation space is small, and the heat dissipation is poor, which is not conducive to the operation and use of the electric vehicle controller. Poor heat dissipation will increase the temperature of the controller. An increase in temperature will slow down the driving speed of the electric vehicle, shorten the service life of the controller, and seriously burn out the controller or even cause a fire. Therefore, it is necessary to design an electric vehicle controller with good heat dissipation performance
