Micro Cooling Fan base design

"Micro Cooling Fan" base design, not simply the motor with the power switch, the wind gear combination. The fan base and the wind box can be separated by a bayonet assembled. In addition to the motor inside the base outside, the following are covered with dense air inlet hole, the air here is the most primitive parts of lessons. Bladeless "Micro Cooling Fan" base is covered with dense hole below the inlet. This layer is horizontally rotating blades, installed after the wind box on the outside can not see. A layer of horizontal blades, the air to the blowing of the wind motor and box after "Micro Cooling Fan" fan effect, has formed a certain stream of air into the internal cavity of the wind box on bladeless fan base.
