Abstract
A method for manufacturing a heat sink includes providing a heat-conducting base with a plurality of open troughs; providing a plurality of heat pipes, each having a heat-absorbing section and a heat-releasing section extending from the heat-absorbing section; the heat-absorbing section being accommodated in one open trough to have the heat pipe engaged with the heat-conducting base; providing a plurality of heat-dissipating fins, each of the heat-dissipating fins having a lower plate and an upper plate extending from the lower plate, the upper plate being folded to form an overlapping portion attached on the lower plate; forming a through-hole in the lower plate and the upper plate at the overlapping portion; and penetrating the through-holes of the heat-dissipating fins by the heat-releasing section of the heat pipe. In this way, the heat-dissipating area in the same height can be increased, thereby improving the heat-dissipating efficiency of the heat sink.
