What is a Cooling fan?

A cooling fan is a device in which an AC motor with blades attached or a DC motor is attached to a casing, and cools an object by the air flow generated by the rotation of the motor. The blade shape can be broadly classified into three types: propeller type, cylindrical type with blades arranged in a circular shape, and long cylinder type with similar blades arranged. Because of its large size and compact structure, it is the most popular cooling fan.
