Abstract
An impeller for a radial-flow heat dissipating fan includes a hub and a plurality of blades surrounding the hub. The blades are connected to a circumference of the hub to allow joint rotation of the hub and the blades. More than one blade include an air inlet side edge and an air outlet side edge. The air inlet side edge of each of the more than one blade has a radial length smaller than that of the air out side edge, thereby increasing an air inlet amount and smoothly changing incoming axial airflow into centrifugal airflow.
