Technical Examples
  1. The present invention is a radial fan having an axial fan blade configuration. The present invention comprises a hub; a first set of blades around the hub; and a second set of blades on the extending part. Therein, the hub comprises a hollow at the center, an axle, a guiding part and an extending part. The gaps are each between every two adjacent blades of the second blade set, having the same distance between every two adjacent gaps. The second set of blades comprises a plurality of blades around outside of the first set of blade and a ring connected with the blades. Accordingly, the structure of the blades may increase the wind pressure, reduce the energy loss by the blade rotation and raise the work efficiency of the blades while the noise is lessened and the working current is lowered.
