Abstract
The present invention provides a heat radiation fan. A frame seat is provided with a through hole, wherein both ends of the through hole respectively form an air inlet and an air outlet, one end of the through hole is provided with a support part, and the frame seat combined with at least two groups of coils is provided with an IC control part electrically connected with coils; a rotor is provided with a rotation shaft and a plurality of blades, wherein the periphery of each blade is provided with a circle of permanent magnet, one end of the rotation shaft is pivoted at the support part of the frame seat, and repulsive magnetic force can be directly produced between the permanent magnets and the coils of the frame seat so that the rotor can be driven to rotate. The present invention overcomes the well-known technical defects and has the advantages of few components, simple structure and convenient manufacture. Magneto resistance for a magnet conducting passage can be omitted so that the heat radiation fan has better rotation torsion. Since the heat radiation fan reduces the magnet conducting elements, such as magnetic pole pieces, metal axle tubes, etc. in the well-known technology, the volume is correspondingly reduced.
