"Micro Cooling Fan" is the use of a space curved fan blades, high-speed rotation of the main wind energy. Previously, large metal sheets are, after molded vane. Then the body and fixed blades mounted blades. Because of molded blade and assembly areas, often fan of static and dynamic balance is difficult to achieve the design requirements. "Micro Cooling Fan" After a long time, since the coating scratches or loss to rust, and the blades dull color, poor color, not suitable for modernization (houses, buildings) and other ventilation and life It needs. Advantages of plastic blades with: one injection molding can not be fitted, correction of energy-saving; "Micro Cooling Fan" light weight, small inertia, rich colors, good color, with good balancing of (plastic wind BLADE good flexibility, high-speed rotation process can automatically adjust the relative position of moderately blades, the blades are in good balance) and decorative effects.
