1. a fan is characterized in that, comprising:

  • The rotor that comprises a plurality of flabellums;

    Motor is used to drive the rotor rotation;

    First denoising structure is formed at the exhaust outlet of the first surface of first flabellum in described a plurality of flabellum;

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

    Wherein, derive by will the flow through air-flow of described first surface of described first flabellum of described first denoising structure, form the first air-flow group, derive by will the flow through air-flow of described second surface of described first flabellum of described second denoising structure, form the second air-flow group, offset the energy that described first air-flow is rolled into a ball and described second air-flow group carries separately, the reduction noise by the mutual collision of described first air-flow group and described second air-flow group.
