An axial cooling fan is a device that creates airflow by using a motor to rotate an impeller housed within a frame. The circulating blades draw air into the fan and expel it on the same parallel axis as the spinning shaft, thus the term axial. The flow is axial at entry and exit.

Axial fans for electronic applications come in different sizes. Usually, the frame is either square or circular.

These fans are available to work with DC power and also AC power of different voltages.
