220V AC Cooling Fan selection principle

"220V AC Cooling Fan" is generally standard parts, profiles may also be provided, as required by the user is cut to length and made of non-standard radiator. Radiator surface treatment have electrophoretic coating or black oxide polarization process, "220V AC Cooling Fan" aims to improve the cooling efficiency and insulation properties. In the natural cooling can be increased by 10% to 15%, in the ventilation and cooling can be increased by 3%, electrophoresis coating can withstand 500V ~ 800V. "220V AC Cooling Fan" radiator manufacturers of different types of thermal resistance of the heat sink is given or give information about the curve, and gives under different conditions, different thermal resistance of the heat.
