Patent ID: 7872870

Claim:
A heat dissipation device for dissipating heat generated by an electronic component mounted on a printed circuit board, the heat dissipation device comprising: a heat sink comprising a base for absorbing heat from the electronic component, the base defining two holes therethrough; and two fasteners respectively engaged in the holes of the base of the heat sink, each of the two fasteners comprising a clamping portion and a frame body disposed at a top end of the clamping portion, the clamping portion comprising a pin extending downwards from the frame body, two wings respectively extending curvedly from a top end of the pin to two opposite lateral sides of the pin, and a clasp formed at a bottom end of the pin, the pin extending through one corresponding hole of the base of the heat sink with the wings located at a top side of the base and the clasp at a bottom side of the base; wherein the clasp is adapted for engaging with the printed circuit board, and the wings are compressed to be flat and contact the base when the clasp clasps a bottom of the printed circuit board; and wherein a gap is defined at a top portion of the frame body for guiding a plurality of wires extending into the frame body.
