Cross-flow impeller and air conditioner
By rationally setting the inlet and outlet angles of the cross-flow impeller, optimizing the blade thickness and shape, adjusting the blade installation angle and chord length, and optimizing the airflow channel, the problems of airflow separation and vortex were solved, thereby improving the aerodynamic performance of the cross-flow impeller and the air delivery capacity of the air conditioner.

Abstract
The application provides a cross-flow impeller and an air conditioner, and relates to the technical field of air conditioners. The cross-flow impeller comprises a wheel disc and a plurality of blades arranged circumferentially on the wheel disc. An outlet angle of the blade is β1, and the value range of β1 satisfies the following relationship: 15°≤β1≤30°. An inlet angle of the blade is β2, and the value range of β2 satisfies the following relationship: 75°≤β2≤90°. The application can improve the aerodynamic performance, efficiency and working stability of the cross-flow impeller by reasonably setting the value range of the inlet angle and the outlet angle of the blade, and thus the air supply of the air conditioner can be increased.
