Axial flow fan
The blades of an axial fan push air to flow in the same direction as the shaft.
When working, the flow direction of most of the airflow is parallel to the axis, which is along the axis direction.
Centrifugal fan
When working, the blades push the air to flow in a direction perpendicular to the axis, the air intake is along the axis direction, and the air outlet is perpendicular to the axis direction.
Cross-flow fan
Cross-flow air flow can generate air flow over a large area and is usually used to cool large surfaces of equipment. The inlet and outlet of this fan are perpendicular to the axis.
Type classification
The working principle of the cooling fan is realized by energy conversion, namely: electrical energy→electromagnetic energy→mechanical energy→kinetic energy. The circuit principle is generally divided into various forms, and the performance of the fan will be different if the circuit used is different. Specifically classified as
