    摘要: A radial-flow heat-dissipating fan includes a casing and a cover mounted to a side of the casing. The casing includes a compartment and a side air outlet, and the cover includes an air inlet. A primary fan wheel is rotatably mounted in the compartment and the primary fan wheel includes a hub and a plurality of radial-flow blades surrounding the hub. An auxiliary fan wheel is mounted in the air inlet of the cover and includes a plurality of axial-flow blades. An airflow transition area is defined between a circumference of the hub of the primary fan wheel, the radial-flow blades, and the axial-flow blades. The axial-flow blades increase axial inlet airflow via the air inlet, with the airflow transition area changing a direction of the axial inlet airflow into centrifugal airflow that is outputted via the side air outlet by the radial-flow blades.

    摘要: 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.

    摘要: 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. The impeller includes an air inlet side and a bottom side. Distribution of the blades at the air inlet side of the impeller is sparser than that at the bottom side of the impeller, thereby increasing an air inlet amount.
