  • Fan and fan wheel thereof
    Patent number: 8043064
    Abstract: A fan and a fan wheel thereof are provided. The fan comprises the fan wheel and a fan cowl. The fan wheel comprises a hub and a plurality of blades. The hub can define an axial direction and a radial direction, and each of the blades has an axial length and a radial length. The portion of each of the blades that extends along the axial direction over a top edge of a side wall of the hub accounts for the axial length in a ratio between one third and two thirds. A connection portion connecting a central portion to the side wall of the hub, and a tip and a tail of each of the blades, as well as a flow conducting portion connecting a top wall to a central hole of the fan cowl, are all rounded. Thereby, the fan and the fan wheel thereof can strengthen the flow rate and reduce the noise generated by the fan.
