The cooling fan is the "power core" of the charging pile cooling system, which accelerates air flow through forced convection
Timely remove the large amount of heat generated by core components such as power modules (such as IGBT), charging modules, capacitors, etc. during the operation of charging stations (especially in fast charging scenarios);

With the continuous increase in the penetration rate of new energy vehicles, the stability of charging piles as core supporting facilities directly affects user experience and equipment lifespan. Among the many components of the charging station, the heat dissipation system is the key to ensuring the long-term efficient operation of the equipment, and as the "power core" of the heat dissipation system, the rationality of the selection and scientific design of the heat dissipation fan are crucial. This article will systematically review the core factors for selecting cooling fans for charging stations, and propose an efficient cooling design scheme based on actual needs.

The difference in lifespan between oil bearing and ball bearing cooling fans will sharply increase with the severity of the environment. In mild environments, the lifespan difference between the two is about 2-3 times, and in harsh environments such as high temperatures and dust, the difference can widen to 5 times or even higher. The specific differences vary depending on different environmental scenarios as follows:

A cooling fan is a device that accelerates air flow through electric power to achieve cooling function, and is widely used in various fields such as electronics, automobiles, and industry. Here is a detailed introduction about it:
