Abstract
A centrifugal fan with axial-flow wind includes a centrifugal fan wheel and a cover shell. The centrifugal fan wheel has a rotating core structure and a plurality of centrifugal vanes arranged around the rotating core structure; a circular wind guide surface is disposed on an internal side of the cover shell and around the rotating core structure and covered onto the centrifugal vanes, such that the circular wind guide surface can change a centrifugal airflow at the external periphery of the centrifugal vane into an axial-flow airflow.
