Dustproof device for laptops

A dustproof device for laptops, comprising a heat dissipating device disposed in a laptop to form the dustproof device for the same;

• the heat dissipating device is disposed on a main computing unit in an interior of the laptop;
• the heat dissipating device includes:
• a fan set for providing heat dissipating wind force and dust removing wind force, comprising:
• a housing having an opening disposed on a lateral side thereof;
• a rotating section disposed inside the housing, wherein on a side of the housing that accommodates the rotating section is correspondingly disposed a cutout section;
• and
• a guiding device disposed inside the housing between the rotating section and a lateral side of the opening, wherein a dust removing path is formed between the guiding device and an inner wall surface of the housing adjacent to the guiding device, wherein the guiding device is a curved sheet body in structure, and the rotating section is arranged adjacent to the guiding device;
• a heat dissipating fin correspondingly disposed on the opening of the fan set to conduct heat generated during the operation of the main computing unit of the laptop out of the laptop by means of the heat dissipating wind force;
• and an indented section disposed in the heat dissipating fin and aligned with the dust removing path to allow dust to be blown out of the laptop through the indented section while the laptop is performing dust removal;
• wherein the indented section passes from a top of the heat dissipating fin to a bottom of the heat dissipating fin.
