Micro Cooling Fan cooling principle

"Micro Cooling Fan" by virtue of the rotating blades to push to accelerate the flow of air. Therefore, the quality of the fan air flow, pressure, noise and other performance indicators, closely related to the merits of the blade design. Although the use of theoretical knowledge of aerodynamics can be its theoretical design, but in fact it is nothing but design also uses empirical method, which is to initially identified several "Micro Cooling Fan" fan model based on experience and a typical design, and through test their performance were analyzed and compared, and improved select the best solution. The more common fan shape, palm-shaped table fan mostly clover, a few also use elongated. "Micro Cooling Fan" radial blades each section are not the same shape and size. Ceiling fans are much more elongated leaf, it is subdivided into wide and narrow two, the former tip width is about 200 mm, which is the width of only 100 mm. Since both the performance closer, but relatively narrow materials province, so the current ceiling fan blades to narrow as much.
