Thermal Conductive Interface Materials Solve the Heat Dissipation Problem of Electric Vehicles

Application and Importance of Thermal Conductive Interface Materials in Heat Dissipation of Electric Vehicles

The rapid development of electric vehicles puts forward higher requirements for battery heat dissipation technology. Thermal interface material (TIM) plays an important role in the heat dissipation of electric vehicles. They are mainly used to fill tiny gaps between electronic components, reduce contact thermal resistance and improve heat dissipation efficiency. Common thermal interface materials include thermal conductive silica gel sheet, thermal conductive gel, thermal conductive gasket, etc. These materials have excellent thermal conductivity and insulation performance, and can effectively conduct heat from heating elements to heat dissipation system.

Specific application scenarios of thermal interface materials in electric vehicles;

1. Battery heat dissipation: In electric vehicles, the battery is one of the main heat sources. Thermal interface materials, such as thermal conductive silica gel sheet and thermal conductive gel, are widely used between battery module and water cooling system to help transfer heat efficiently and protect battery pack. For example, the thermal conductive silica gel sheet can closely adhere to the core components such as battery pack, motor and electronic control, improve the heat conduction efficiency and ensure the stable operation and safety of the battery system.

2. Heat dissipation of motor and electronic control system: The motor and electronic control system will also generate a lot of heat during operation. Thermal interface materials can effectively conduct the heat generated by these components to the heat dissipation system, and prevent performance degradation and damage caused by overheating.
