Patent ID: 7633755

Claim:
A heat dissipation device assembly adapted for dissipating heat generated by a plurality of electronic components mounted on a printed circuit board, the heat dissipation device assembly comprising: a heat sink adapted for absorbing the heat from one of the plurality of electronic components, said heat sink having a plurality of screws preassembled thereto; a fan being mounted on a lateral side of the heat sink; and a fan duct being secured to the fan and sandwiching the fan between the heat sink and the fan duct, the fan duct comprising a top plate, a pair of lateral plates extending downwardly from two lateral sides of the top plate, and a cover coupling the top plate with the pair of lateral plates, guiding means being formed on the cover and located in an interior of the fan duct, adapted for guiding a screwdriver to extend through the interior of the fan duct to reach and fit with a corresponding screw, thus realizing a convenient and quick assembly between the heat dissipation device assembly and the printed circuit board by operating the screwdriver to fasten the corresponding screw to the printed circuit board.
