Electric vehicle controller cooling solution

The electric vehicle controller is the core control device used to control the start, operation, advance and retreat, acceleration and deceleration, stop and other electronic components of the electric vehicle. It is like the brain of the electric vehicle and is an important part of the electric vehicle. Therefore, the normal operation of the electric vehicle controller is related to the performance and safety of the electric vehicle, so the major electric vehicle manufacturers pay special attention to the heat dissipation of the electric vehicle controller.

As a manufacturer with more than ten years in the field of high-power radiator manufacturing, Zerode Thermal energy has made great achievements in the research and development of electric vehicle controller heat dissipation, and has conducted thermal design, thermal simulation, thermal management testing and radiator production of electric vehicle controllers for many new energy vehicle manufacturers. The following is the electric vehicle controller cooling solution provided by Zerode Thermal for a brand of electric vehicles at home and abroad.

The cooling scheme of electric vehicle controller adopts water cooling design

The cooling component is divided into two parts:

Frame and water-cooled plate structure, and finally assemble the two into a whole.

The back of the heat dissipation plate is designed to be in full contact with the heat element, which can improve the heat dissipation efficiency of the heat dissipation area.
