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.

The DC blower uses direct current to convert it into mechanical energy to drive the wind wheel to rotate. The air inlet and outlet are in a vertical wind direction, and the air is continuously compressed to generate a large amount of air for blowing.

Frameless DC fan is the fluid that frameless DC fan through the fan impeller twice, the fluid flows in the radial direction and then frameless DC fan out in the radial direction.
