"Micro Cooling Fan" blades push air to flow in the same direction with the shaft. Cooling axial flow fan impeller and propeller somewhat similar, it is at work, most of the airflow flows parallel to the axis, that is to say in the axial direction. "Micro Cooling Fan" when the inlet air flow is zero static pressure of free air time, its power consumption is the lowest, when the operation will rise along with the air flow back pressure power consumption will increase. "Micro Cooling Fan" is usually installed in the electrical equipment cabinet, sometimes integrated in the motor, because of its compact axial fan structure, you can save a lot of space and easy installation, and therefore widely used.
