Abstract

An impeller for radial-flow heat-dissipation fan comprises a hub, at least one supporting member, a plurality of first blade sections, and a plurality of second blade sections. The hub employs the supporting member to connect to the blades. The impeller has an inlet side, and a bottom side. Number of the first blade sections adjacent to the inlet side of the impeller is less than those of the second blade sections adjacent to the bottom side of the impeller. Thus, when the impeller rotates, the lesser number of first blade sections adjacent to the inlet side can efficiently expand an axial inlet airflow.
