Abstract
A dustproof device for laptops comprises a heat dissipating device disposed in a laptop to form a dustproof device for the same, wherein 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 and a heat dissipating fin. The fan set includes a housing, a rotating section and a guiding device, wherein on a lateral side of the housing is disposed an opening, the rotating section is disposed inside the housing, the guiding device is disposed inside the housing between the rotating section and a lateral side of the opening, and a dust removing path is formed between the guiding device and an inner wall surface of the housing adjacent to the guiding device. The heat dissipating fin is correspondingly disposed on the opening of the fan set, and an indented section is disposed in the heat dissipating fin in correspondence 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 without a need to dispose a dust removing hole on the housing of the laptop.
