Heat dissipation plate and controller heat dissipation structure

Abstract

The invention relates to the field of electric vehicles, and discloses a heat dissipation plate and a controller heat dissipation structure. The heat dissipation plate comprises an upper-layer substrate and a lower-layer heat dissipation fin part, a flat area is arranged on the upper surface of the upper-layer substrate and used for installing a controller, and the lower-layer heat dissipation fin part is connected to the lower surface of the upper-layer substrate, the bottom end of the lower-layer heat dissipation fin part is connected with a mounting frame, a first mounting surface and a second mounting surface are arranged at the bottom end of the lower-layer heat dissipation fin part, the first mounting surface is lower than the second mounting surface, at least one of the first mounting surface and the second mounting surface abuts against the mounting frame, the height difference between the first mounting surface and the second mounting surface is smaller than a preset threshold value, so that the first mounting surface and the second mounting surface can be connected with the mounting rack by adopting connecting pieces with the same length specification. The heat dissipation plate and the controller heat dissipation structure provided by the invention can dissipate the heat of the controller through the mounting rack, are suitable for controllers and mounting racks of various structures, improve the universality and reduce the development cost.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a heat dissipation plate and a heat dissipation structure of a controller. Background technique [0002] With the progress of modern life, electric vehicles have become a common means of transportation for people's life and travel due to their small size, convenient use, flexibility, and fast speed. The electric vehicle controller is like the brain of the electric vehicle. It is used to control the start, stop, operation, speed, etc. of the electric vehicle. It is an important part of the electric vehicle. The controller often causes a series of problems due to excessive temperature, so the controller is often equipped with a heat dissipation mechanism. However, the existing controller heat dissipation mechanism generally has compatibility problems: on the one hand, the controller and the radiator are poorly matched, and one radiator is often only suitable for one cont...

AI Technical Summary

Problems solved by technology

However, the existing controller heat dissipation mechanism generally has compatibility problems: on the one hand, the controller and the radiator are poorly matched, and one radiator is often only suitable for one controller; on the other hand, the radiator is poorly matched with the installation of the electric vehicle , it is necessary to design radiators with different structures according to the vehicle installation structure

Due to the above two reasons, the radiator needs to be redesigned regardless of the change of the controller or the structure of the vehicle model, and the development cost is high.
