In the "Micro Cooling Fan" internal blades, attached to a pre-filled with the magnetic rubber magnets. Surrounded by silicon, axial part of the winding two coils and a Hall sensor component as a synchronous detection device, controls a group of circuit which two coils wound around the axis of rotation job. Silicon have different magnetic poles, the magnetic pole and the repulsive force absorbing rubber magnet. When the suction fan of static friction is greater than the repulsion, the natural rotation of the blades. Since the Hall sensor component provides a synchronization signal, the fan was able to continue to operate, as its running direction, to follow Fleming's right-hand rule decision. And with the "Micro Cooling Fan" associated wind is how come? Air volume means the fan-ventilated area and product area plane speed. Ventilation area is exports minus scroll area at the projected area of the tongue. Plane speed velocity gas stream through the entire plane, the unit is m / s. Flat rate constant, "Micro Cooling Fan" blade impeller diameter, the greater the ventilation area, the greater the amount of wind. The larger the amount of wind, cold air heat absorption is greater, can take more heat transfer of air flow, cooling effect is more obvious.
