FIELD: The use of a "220V Cooling Fan" of improved structure, and more particularly in the cylindrical space restrictions can reduce eddy current effects of blade structure.
BACKGROUND: High-performance, low-noise fan factory has always been the pursuit of each objective, and "220V Cooling Fan" blade design is the dominant factor in this two biggest key, so the fans are all brains manufacturers to design high performance low noise fan.
Technical advantages: Fold the edge of the blade-type supercharger, noise reduction "220V Cooling Fan" device that can eliminate eddy axial fan blades in the confined space of the cause, reduce noise, increase air pressure. Designed to improve the traditional fan blades.
