Fold edge 220V Cooling Fan

    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 "dota2雷竞技下载 " 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 "dota2雷竞技下载 " 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.
