Axial Flow Fans are a common ventilation device. Their basic working principle is to generate and promote airflow through the rotation of the impeller. Specifically, when the motor drives the impeller to rotate, multiple blades fixed around the impeller will rotate accordingly. The shape and angle of these blades are designed very precisely, which can effectively inhale air and push it along the axis of the fan, thereby achieving the purpose of ventilation and air exchange.
When the Axial Flow Fan is working, the airflow is sucked in from one side of the fan (the air inlet), and after being pushed by the blades, it is discharged from the other side (the air outlet). During the whole process, the airflow flows in a straight line along the axis of the fan, with a high flow rate and a relatively low static pressure. This design feature enables the axial flow fan to efficiently generate a large amount of airflow, which is suitable for occasions where a large amount of air flow is required without high pressure.
In addition, the blade design and arrangement of the axial flow fan are crucial to its performance. Reasonable blade shape, angle and arrangement can ensure that the airflow obtains enough energy and power during the rotation process, so as to drive them to move along the axis of the fan.
To sum up, Axial Flow Fans generate and flow air through the rotation of the impeller and the push of the blades. They have the characteristics of high efficiency, large air volume, and low pressure, and are widely used in ventilation, cooling, transportation and other fields.
