First of all, before we know the functions of cooling fans, we need to know the classification of cooling fans. Cooling fans are mainly divided into axial flow cooling fans, centrifugal cooling fans, mixed-flow cooling fans, cross-flow cooling fans, etc. Their working principle is the process of converting electric energy into electromagnetic energy, mechanical energy and kinetic energy. The common bearing structures of cooling fans mainly include ball bearings, oil-bearing bearings and magnetic bearings, and the main function of cooling fans is to ventilate and cool the products. Its main application fields include computers, medical equipment, frequency converters, refrigeration equipment and so on.
