24V DC Cooling Fan principles and performance

"24V DC Cooling Fan" is usually divided into the following three categories:
An axial flow: flow outlet direction axis in the same direction.
2 centrifugal: the use of centrifugal force will throw out the airflow along the blade.
3 Francis: Has two kinds of airflow can approach.
"24V DC Cooling Fan" principle
Principle: The cooling fan works by energy conversion to achieve, namely: energy - electromagnetic energy - kinetic energy. Other circuit principles are generally divided into a variety of forms, using different circuits, there will be differences in the performance of the fan.
"24V DC Cooling Fan" consists of: fan box, blades, bearings, PCB control circuit, the drive motor
