ABSTRACT:
A heat sink fan has a fan motor provided with blades, a rectangular upper casing for holding the fan motor, and a rectangular lower casing fixed to the upper casing. The lower casing has a bottom portion and fin dissipating fins erected perpendicularly from the four side edges of the bottom portion. The upper and lower casings are fixed together by a mechanically interlocking mechanism consisting of a combination of pawls and pawl receiving portions, a combination of projections each having an inflated portion and cavities or a combination of hooks and engaging grooves formed or in the upper or lower casing. Fin portions are formed on the whole area or the area except for the fan motor and the blades to increase a heat dissipating efficiency.
