Here we simply give some basic principles about "220V AC Cooling Fan" of other information, the fan works by energy conversion to achieve. Namely: electricity electromagnetic energy → → → kinetic energy to mechanical energy. Its circuit diagram is generally divided into a variety of forms, the use of different circuits, there will be differences in the performance of the fan.
"220V AC Cooling Fan" is usually divided into the following three categories:
1. Axial: air flow direction and the axial direction of the same outlet.
2. Centrifugal: "220V AC Cooling Fan" use centrifugal force to throw out the airflow along the blade.
3. Francis: With more than two kinds of airflow mode.
