Abstract

An impeller structure for axial-flow heat-dissipating fan comprises a hub and a plurality of blades which are symmetrically arranged around an outer circumference of the hub in a predetermined inclined angle. Each of the blades has a leading edge, a trailing edge, a radial inner edge, and a radial outer edge. In a longitudinal direction, each of the blades overlaps the adjacent so as to define a first longitudinally upper zone and a second longitudinally lower zone on each of the blades. Both of the longitudinally upper and lower zones of the blades extend from the radial inner edge and space from the radial outer edge. Thus, when the impeller rotates, the longitudinally upper and lower zones efficiently increases air flow of the impeller and reduce noise thereof.
