ABSTRACT:
A heat dissipating fan comprises a base unit having an axial sleeve, a dynamic bearing having a shaft section, a stator unit securely around the axial sleeve and a rotor unit. The rotor unit has a hub with a through hole to be jointed to the shaft section. A barrel core is positioned at the inner side of the hub corresponding to the through hole for receiving the shaft section. A connection element engages with the shaft section to secure the connection between the hub and the shaft section. Thus, the heat dissipating fan is assembled quickly, easily and precisely.
