Axial flow fan is widely used in life, but many people don't know whether it is a DC fan or not. In fact, DC fan is only one kind of axial flow fan. Axial flow fan is the same airflow with the axial direction of the fan blade, such as electric fan and air conditioning fan. It is called "axial flow" because the gas flows parallel to the fan shaft. Axial fan is usually used in the situation of high flow and low pressure. Axial flow fan is mainly composed of fan impeller and shell, simple structure but high data requirements

The wind turbine can be divided into axial flow, centrifugal flow and mixed flow according to the direction, that is, straight out, straight out 90 degrees, straight out 45 degrees.

The DC fan device drives the rotating fan impeller by inputting DC power and DC motor, so as to realize the mechanical energy conversion process of DC fan energy. The biggest feature is the optional DC DC fan motor.

The above is the introduction of axial-flow fan is DC fan, and other axial-flow fan problems can be concerned about dongxingyue to learn more about fan knowledge.
