Abstract
A centrifugal heat dissipation fan suited for a laptop computer is provided. The centrifugal heat dissipation fan includes a housing having a plurality of recesses, a hub rotating disposed in the housing, and a plurality of blades disposed at side of and surrounding the hub. The blades are rotated in a direction along with the hub. The recesses face toward the blades, and a contour of each of the recesses is tapered along the direction. An airflow on a surface of the housing enters the recess when the centrifugal heat dissipation fan is operated. After the airflow being gathered together because of the tapered contour, the airflow is squeezed out of the recess and flows toward the blades.
