Increase along with the electronic product radiating amount, produce greater pressure and air quantity when needing fan work, therefore, industry desired design always goes out the multi-direction air-flow of a kind of energy generation, and the electric fan that blast and air quantity are larger dispels the heat to electronic product effectively with realization.
The model utility content:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of high efficiency and heat radiation electric fan that can produce multi-faceted air-flow is provided.
In order to solve the problems of the technologies described above, the utility model has adopted following technical proposals: it comprises this high efficiency and heat radiation electric fan at least: a wheel hub is provided with the installation position of installing for the rotating shaft of drive motor in wheel hub; One airblast blade group, this airblast blade group comprise that quantity is odd number and more than or equal to 3 airblast blade, and this airblast blade is arranged at described wheel hub periphery, and wherein, the inner of this airblast blade is fixed on the excircle of wheel hub; One axial blade group, this axial blade group comprises: quantity is odd number and more than or equal to 3 airblast blade, this axial blade is arranged between every two airblast blades and is fixed on described wheel hub, and be formed with the gap between this axial blade and airblast blade, make axial blade and airblast blade be interspersed in the wheel hub periphery.
Furthermore, in technique scheme, the width of described axial blade is less than the thickness of described wheel hub, and axial blade is shorter than described airblast blade.
Furthermore, in technique scheme, the outer end of described airblast blade is the cambered surface of a distortion, and the width of the inner of this airblast blade is more than or equal to the width of described axial blade.
Furthermore, in technique scheme, the inner of described airblast blade connects by a strengthening rib circle with respect to the opposite side of the installation position of described wheel hub, and a side of described axial blade is connected with this strengthening rib circle.
Furthermore, in technique scheme, described axial blade is circular arc, this axial blade end towards with the opposite direction of described airblast blade outer end distortion.
After adopting technique scheme, the utility model has following beneficial effect compared with prior art: during the utility model work, airblast blade and axial blade rotarily drive surrounding atmosphere and flow, wherein, airblast blade produces the air-flow of 180 ° of directions (consistent with the airflow direction that enters), axial blade can produce the air-flow of 90 ° of directions (direction vertical with the airflow direction that enters), and blast and air quantity are larger, make this multi-faceted air-flow can realize different product is dispelled the heat, meet the different needs.In addition, the very big degree enhancing radiating effect of the multi-faceted air-flow that produces of the utility model.
