The heat dissipation of new energy vehicle charging piles has been upgraded, and TIF's two-component thermal conductive gel has become the key choice.

High temperatures are the "invisible killer" for the operation of charging piles. Equipment failures caused by poor heat dissipation account for over 40%, and this is the core bottleneck restricting the upgrade of charging piles to higher power and higher density. This not only leads to a reduction in charging efficiency by more than 30%, accelerates the aging of core components such as IGBT modules and capacitors, but in adverse circumstances, may also cause short circuits, fires and other safety accidents. The shortcomings of traditional heat-conducting materials have become increasingly prominent.
 

The mainstream heat-conducting materials currently used in charging piles have common limitations: the heat-conducting silicone grease tends to dry out and lose its effectiveness over time, unable to maintain long-term heat dissipation; the heat-conducting gaskets lack sufficient flexibility and are difficult to fit into the gaps of irregular components, resulting in heat conduction dead zones. However, TIF's two-component heat-conducting gel, with its dual advantages of "flexible adaptation and effective heat conduction", accurately addresses these problems and has become the key choice for upgrading the thermal management of charging piles.

As a paste-like flexible thermal conductive medium, thermal conductive gel does not require curing and has excellent fluidity. It can fill the tiny gaps between components and heat dissipation structures in all directions, even penetrating into the precise pin gaps, achieving seamless heat conduction and significantly reducing interface thermal resistance. After curing, it still maintains a 30%-50% high deformation rate, which can cope with the thermal expansion and contraction and vibration impact during equipment operation, and remains firmly attached without falling off for a long time, ensuring the stability of heat dissipation.

In high-power and complex scenarios, the comprehensive advantages of thermal conductive gel are more pronounced. For fast charging stations with power above 180kW, the thermal conductivity of high thermal conductive gel can reach 1.5-8.0W/m·K, effectively conducting the heat of the module and improving the heat dissipation efficiency by more than 40% compared to traditional materials. When adapting to liquid-cooled charging stations, it has both thermal conductive and sealing functions, preventing coolant leakage and being compatible with automated dispensing processes, thereby enhancing production efficiency. For outdoor conditions, the thermal conductive gel can withstand temperatures ranging from -45℃ to 200℃, is resistant to aging and UV radiation, and can easily adapt to protection standards, meeting the complex environmental requirements for outdoor installation of charging stations.
