US Patent 7426956 Heat dissipating apparatus

A heat dissipating apparatus (10) includes a base (20), a plurality of stacked fins (30), and at least a heat pipe (40). The base absorbs heat from a heat-generating component. Each of the fins includes a main body (32), and a plurality of projection members (33) extending from the main body. The projection members of a first fin connect the projection members of a second fin. The projection members form a first heat transfer path for transferring heat from the base to the fins. The heat pipe includes a heat-absorbing portion (42) thermally contacting with the base, and a heat-dissipating portion (44) contacting with the fins. The heat pipe forms a second heat transfer path for transferring the heat from the base toward the fins.
