"220V Cooling Fan" of the structure: Rotor: by magnets, blades and shafts composition; stator: There silicon steel sheet, coil and bearing components; control circuit: induction by IC magnet N. S. Pole coil via the circuit control its conduction and produce internal excitation of the rotor to rotate.
"220V Cooling Fan" Type: Axial fan, AC fan, cooling fan
Series and parallel fan fan: Fan
Series Fan: The results of a series fan is pressure to increase, but the wind changed. Time is not the way to solve the problem of cooling fan, is generally used in the past is the use of too much wind resistance, to ensure air flow.
Parallel "220V Cooling Fan": Parallel dual fan pressure unchanged, but the wind will rise. Increase air volume to increase the cooling effect and therefore, if the design power dissipation may be considered too small to resolve the fan increases.
