There are significant differences between axial flow fans and mixed flow fans in terms of working principle, structural characteristics, performance parameters, and application fields:

Working principle:

Axial flow fan: The thrust generated by the rotation of the impeller causes air to flow axially.

Mixed flow fan: Combining the characteristics of axial flow fan and centrifugal fan, the air flows in both axial and radial directions, generating lateral airflow, known as "mixed flow".

Structural features:

Axial flow fan: The impeller diameter is large, the speed is slow, the structure is relatively simple, usually composed of single or multiple stages, and pressure is generated by the action of the blades on the air.

Mixed flow fan: The impeller diameter is generally large, the speed is slow, the structure is complex, and it is composed of axial and radial parts to achieve airflow mixing.

Performance characteristics:

Axial flow fan: usually has a high air volume coefficient and a low air pressure coefficient, providing high air volume but relatively low air pressure.

Mixed flow fan: With high and low wind pressure coefficients, it provides high air volume and pressure, while also having relatively low noise.

Application scenarios:

Axial flow fan: suitable for occasions that require airflow transportation, such as ventilation, cooling, ventilation, smoke exhaust, etc.

Mixed flow fan: suitable for situations that require higher air volume or require both air volume and pressure, such as air conditioning systems.
