Centrifugal fan introduction related knowledge

Centrifugal fan is a common and important type of fan, which is widely used in refrigeration, ventilation and air conditioning systems and other fields. Its working principle is based on the principle of centrifugal force and kinetic energy conversion, and the air is sucked in by rotating the impeller and discharged by centrifugal force.

Centrifugal fans are composed of main parts such as impellers, driving devices and casings.

The impeller, also known as the volute, is surrounded by a series of curved blades, which accelerate the air through rotation and generate a strong airflow. The drive unit rotates the impeller, common drive units include electric motors, belt drive systems or direct drive systems. The shell is used to seal and guide the air flow, ensuring that the air flows in the correct direction.

Compared with other types of fans, centrifugal fans have some advantages and characteristics of their own.

The first is that they have high air volume and high pressure capabilities, which can provide stronger airflow and are suitable for occasions that require a large amount of air flow and higher airflow pressure requirements. In addition, centrifugal fans are able to pipe airflow over long distances, overcome pipe resistance and air resistance, and allow air to be efficiently piped to where it is needed.

Centrifugal fans also perform well in cooling applications.

Thanks to their high air volume and pressure, they are able to expel hot air quickly and carry it away, providing better cooling. This makes centrifugal fans ideal for cooling computers, cooling electronics, and industrial and commercial transformation systems.

Another notable feature is the relatively low noise level of centrifugal fans.

Due to the reduced impeller speed, the noise generated when the air passes is reduced. This makes centrifugal fans more popular in noise-sensitive applications.

In addition, centrifugal fans also have advantages in terms of space utilization.

Their relatively compact design results in efficient space scaling for applications where space is limited. Whether it’s a compact electronic device or a ventilation system, centrifugal fans are able to provide high volumes of air movement while saving valuable space.
