1. a fan, is characterized in that, comprising:

  • Comprise the rotor of multiple flabellum;

    Motor, rotates for driving rotor;

    First denoising structure, is formed at the air outlet of the first surface of the first flabellum in described multiple flabellum;

    Described first denoising structure is the first diversion trench, and described first diversion trench has the first training wall and the second training wall;

    Second denoising structure, is formed at the air outlet place of the second surface of described first flabellum;

    Described second denoising structure is the second diversion trench, and described second diversion trench has the 3rd training wall and the 4th training wall;

    Described first training wall is identical with the spacing of described 3rd training wall and the 4th training wall with the spacing of the second training wall;

    Described 3rd training wall between described first training wall and described second training wall and described 4th training wall between described first training wall and described second training wall beyond position, or described 4th training wall between described first training wall and described second training wall and described 3rd training wall between described first training wall and described second training wall beyond position;

    Wherein, by described first denoising structure, the air-flow flowing through the described first surface of described first flabellum is derived, form the first air-flow group, by described second denoising structure, the air-flow flowing through the described second surface of described first flabellum is derived, form the second air-flow group, roll into a ball mutually to collide by described first air-flow group and described second air-flow and offset described first air-flow and to roll into a ball and described second air-flow rolls into a ball the energy carried separately, reduction noise.
