Piece 161 and third plectrum 162 are also flat strip, the air flowing for adding secondary flabellum 160 when can accelerate flabellum rotation
Speed, and then improve the heat-sinking capability of radiator fan 100.Preferably, one group, two groups, three groups or more multiple groups pair can be used
Flabellum 160.
In this present embodiment, radiator fan 100 further include fan case 170.Main flabellum 110, shaft, the first magnet 130 and
Two magnets 140 are respectively positioned in fan case 170, and shaft is fixed on the bottom of the inner space of fan case 170 far from one end of bearing 120,
Fan case 170 is equipped with air outlet far from one end of electromagnet 150.The distance of first end of shaft to main flabellum 110 is arrived less than shaft
The distance of the second end of main flabellum 110.Specifically, using shaft as separation, main flabellum 110 can be divided into equipped with electromagnet 150
One end and be not provided with one end two parts of electromagnet 150；The main flabellum 110 of part equipped with electromagnet 150 be mainly used for for
The main rotation of flabellum 110 provides power, and the main flabellum 110 of part for being not provided with electromagnet 150 is mainly used for accelerating in fan case 170
Speed air flow.Therefore, electromagnet 150 is set to one end far from air outlet, and make to be not provided with electromagnet 150 that
The length of the main flabellum 110 in part is greater than the length of the main flabellum 110 of part equipped with electromagnet 150, can effectively improve main fan
Speed air flow when leaf 110 rotates in fan case 170, and then accelerate the radiating rate of radiator fan 100.
