Patent ID: 7304842

Claim:
A heat sink for dissipating heat generated by an electronic device in a computer system, the heat sink comprising: a heat pipe structure formed from a single piece of heat pipe material having a plurality of evacuated passages, the heat pipe structure including: a planar interface portion configured to be positioned proximate to the electronic device; a planar leg portion extending away from the interface portion, wherein the leg portion is at least generally perpendicular to the interface portion, and wherein the interface portion extends away from the leg portion in a first direction; a planar body portion vertically offset from the interface portion by the leg portion, wherein the body portion is at least generally parallel to the interface portion, and wherein the body portion includes a first portion of the evacuated passages which extends away from the leg portion in the first direction and a second portion of the evacuated passages which extend away from the leg portion in a second direction, the second direction being opposite to the first direction; and a working fluid that cycles through the evacuated passages of the heat pipe material to absorb heat from the electronic device at the interface portion of the heat pipe structure and transfer the heat to the body portion of the heat pipe structure.
