The wind direction is consistent and discharged to the outside of the chassis.
The cooling fan
The working principle is based on energy conversion, that is: electrical energy → electromagnetic energy → mechanical energy → kinetic energy.
Classification
1. Axial fan: The blades of the axial fan push the air to flow in the same direction as the shaft. The impeller of an axial flow fan is somewhat similar to a propeller. When it is working, most of the airflow flows parallel to the axis, in other words, along the axis direction.
2. Centrifugal fan: When the centrifugal fan works, the blades push the air to flow in the direction perpendicular to the axis (i.e. radial direction). The air intake is along the axis direction, while the air outlet is perpendicular to the axis direction.
3. Mixed flow fan: This type of fan has a higher wind pressure due to the conical shape of its blades and outer cover. Compared with the axial flow fan of the same size and other comparable performance, the noise of the centrifugal fan is lower. lower.
