Through DC voltage and electromagnetic induction, electrical energy is converted into machinery to drive the rotation of the blades, which are collectively referred to as DC fan.

According to the principle classification, fans can be divided into two categories: AC axial fans and centrifugal fans. These two types of fans have different structures, different working principles, and different operating characteristics.

This AC axial fan has many different characteristics in terms of structural configuration, design method, and internal flow phenomenon, and it is not easy to grasp the fan's low-noise design and internal flow mechanism.

Frameless DC Fans are available in blower, mixed-flow, and axial frameless models making them well-suited for a range of applications. As heat sources become smaller and more densely packaged, thermal-solution designers reduce weight and size wherever possible.
