Abstract:
1. A heat dissipating apparatus comprising: a base configured for absorbing heat from a heat generating component; a plurality of fins stacked together along a predetermined direction, each of the fins comprising a main body, and a plurality of projection members extending from the main body, the projection members of a first fin connecting with the projection members of a second fin, the projection members together forming a first heat transfer path for transferring the heat from the base to the fins; and at least a heat pipe thermally connecting the base with the fins to form a second heat transfer path for transferring the heat from the base to the fins, the heat generated by the heat generating component being transferred to the fins via the first and second heat transfer paths, thereby increasing the heat dissipating efficiency of the heat dissipating apparatus; wherein the first fin is coupled with the second fin via a plurality of locking members; and wherein the locking member comprises an abutting plate extending from the main body, a flange extending from one end of the abutting plate, and a finger offsets from a free edge of the flange, the main body defines a plurality of cutouts between the fingers and the main body, the fingers of the first fin extend through the cutouts of the main body of the second fin, and engage the main body of the second fin.
