Heat dissipation mechanism

Abstract

A heat dissipation mechanism includes at least one fixing member and at least one heat pipe. The heat pipe has a heat-dissipation section and a heat-absorption section bearing on one face of the fixing member. The fixing member includes a plurality of clamp sections protruded from two axially opposite edges of the fixing member. The clamp sections respectively define a receiving space, and the heat-absorption section has a plurality of connecting segments received in the receiving spaces, so that the heat pipe is connected to the fixing member via the clamp sections to form an integral unit. With these arrangements, the heat dissipation mechanism can have effectively increased heat transfer efficiency and be manufactured at reduced cost.
