Notebook fan and mounting method thereof

The invention discloses a mounting method of a notebook fan. The fan comprises a housing, a rotary fan blade assembly and a bottom plate, wherein the housing comprises a first surface and a second surface which are arranged in parallel; the rotary fan blade assembly is mounted in the housing and positioned between the first surface and the second surface; the bottom plate is mounted outside the housing, spaced from the first surface and parallel to the first surface; when the fan is assembled on a notebook, a gap matched with the bottom plate is reserved in a bottom housing of the notebook, the fan is mounted on the notebook from the gap, the gap is blocked by the bottom plate, and the bottom plate and the bottom housing are positioned on the same plane. According to the fan provided by the invention, the bottom plate is added and spaced from the housing, so that the influence of rotation of the fan on the bottom plate can be effectively reduced and the fan strength can be enhanced; the fan is a component independent from the complete notebook, so that when the fan needs to be repaired and cleaned, the fan can be independently dismounted by only dismountinglocking parts on the bottom plate, and then the complete notebook can be prevented from being frequently dismounted.
