Heat dissipation application of thermal conductive materials in new energy vehicles

The power source of a new energy vehicle is the vehicle power battery pack as the output source, and it is driven by the motor and electronic control to drive the car. The battery pack, motor and electronic control of a new energy vehicle are the key to its performance, so good thermal management is the key The key to automotive R&D and design.

New energy vehicles are large-scale electrical equipment. All electrical equipment has a common problem: heat generation. The high power of new energy vehicles means that they generate more heat during operation. High temperatures will accelerate the aging of batteries and parts. , and speed up the power loss, if the heat has been accumulated and not dissipated to the outside in time, it is easy to cause the internal temperature of the car to be too high and cause spontaneous combustion, so it is necessary to do a good job of heat dissipation.

The heat conduction effect of heat in the air is very poor, so if only relying on the heat source itself to dissipate heat, the heat dissipation effect will be poor, so people will use heat dissipation devices and thermal conductive materials. Conducted to the heat dissipation device, and then the heat dissipation device is conducted to the outside, and the function of the heat conduction material is to fill the gap between the heating device and the heat dissipation device in the new energy vehicle, remove the air in the gap, and reduce the contact thermal resistance between the two, thus Improve heat dissipation.

Although thermal conductive materials do not account for much in the overall materials of new energy vehicles, their role is very important, providing a good environment for the stable operation of new energy vehicles.
