The classification of the cooling fan

The classification of the cooling fan:


cooling fan according to the power supply can be roughly divided into two categories: AC fan and the DC fan


so what is the principle of it: the working principle of the fan is implemented according to the energy conversion, namely: electricity - — Electromagnetic energy - — Mechanical energy - — Kinetic energy. The circuit principle generally divided into a variety of forms, the circuit is different, the performance of the fan will naturally have differences.








used to drive the cooling fan of the input voltage:


when using AC fan: 110 v, 220 v, 380 v


when using DC fan: 5 v, 12 v and 24 v, 48 v





cooling fan according to the blade and the air flow pattern can be roughly divided into: cross flow fan, centrifugal fan, air blower, axial flow fan.








axial flow fan, axial flow fan blades air moving in the same direction as the axial flow, most of the air flow direction parallel to the axis.


the centrifugal fan, centrifugal fan, blade air moving in a direction perpendicular to the axis phase ( The radial) Flow, inlet is along the axis direction, and the gas is perpendicular to the axis of the


that they have what characteristics?


relative to the axial flow fan with high flow rate, medium wind pressure and centrifugal fan limited flow rate, high wind pressure.
