Background

The cross-flow fan is also called cross-flow fan, which is firstly proposed by french engineers in 1892 by molter, and the impeller is multi-blade type and long cylindrical shape and has forward multi-wing blades.

The cross-flow fan has the characteristics of moderate flow, moderate pressure and low noise. The axial length of the cross flow fan is not limited, and the air flow at the air outlet is distributed uniformly along the axial direction of the cross flow fan. Compared with an axial flow fan, the cross flow fan has the advantages that the airflow of the cross flow fan penetrates through the impeller to flow, the airflow is acted by the blades twice, and the airflow can be conveyed to a longer distance under the low-noise condition. The airflow of the cross-flow fan is forcibly turned in the impeller, so that the pressure loss is large and the efficiency is low. The cross-flow fan impeller adopts forward blades.
