Abstract
A heat-dissipating fan with an upward air-guiding member is provided. The heat-dissipating fan includes a housing, an impeller having a hub and a plurality of blades disposed around the hub, a base disposed inside the housing for supporting the impeller thereon, and an air-guiding member disposed between the base and the housing, wherein the air-guiding member has at least one inclined edge on the windward side or its opposite side relative to the horizontal line perpendicular to the axis of the heat-dissipating fan.
Claims19
A heat-dissipating fan comprising:
- a first housing having an outwardly expanding part and a cylindrical part;
- a first impeller having a hub and a plurality of blades arranged around the hub;
- a base disposed inside the housing for supporting the first impeller;
- and
- an air-guiding member disposed between the outwardly expanding part and the base, having a first edge with a first inclined angle relative to a line perpendicular to an axis of the heat-dissipating fan, wherein the first housing, the base and the air-guiding member are integrally formed to be a single piece and the air-guiding member has one end connected to the base and the other end connected to inner walls of the cylindrical part and the outwardly expanding part.
