The so-called "220V AC Cooling Fan" air-cooled radiator, its cooling and heating by the principle that objects in close contact with the metal heat sink, the heat generated by the heat conduction to the object has a larger heat capacity and heat dissipation area of the heat sink, then use "220V AC Cooling Fan" diversion effect making the air quickly through the heat sink surface, accelerating thermal convection between the heat sink and the air that forced convection cooling. Therefore, an excellent air-cooled radiator will have three conditions: the workmanship, reasonable design, materials suitable heat sink, with a strong performance, stable, long-life "220V AC Cooling Fan", as well as excellent the overall structure and installation design.
