Abstract
In a heat sink and the manufacturing method thereof, the heat sink includes heat dissipation fins and heat pipes, and the heat dissipation fins have through holes for the heat pipes to pass through. The heat dissipating fins also have a notch formed at the peripheral of the through hole and communicating with the through hole, and openings formed at two sides of the notch, respectively. According to the manufacturing method, after the heat pipe is assembled with the heat dissipating fin, press strips pass through the openings and are pressed inwardly to reduce the notch to make the notch and the heat pipe plastically deformed. Finally the press strips are removed.
