Patent ID: 8286693

Claim:
A heat sink assembly comprising: a base plate having a top surface and a bottom surface, the bottom surface having an open channel formed therein, the channel having at least one first region and a second region; at least one heat pipe contained in said open channel, each said heat pipe comprising at least one evaporator section and at least one condenser section, wherein the at least one evaporator section and at least one condenser section are arranged in the open channel such that a common plane that is parallel to a plane of the bottom surface at the second region passes through both the at least one evaporator section and the at least one condenser section, and wherein at least two evaporator sections are juxtaposed side by side in the second region of said channel, and each said condenser section is in a respective said first region of said channel; and a heat dissipating element which dissipates heat from said top surface of said base plate, said heat dissipating element comprising one of cooling fins and a cold plate on said top surface, wherein said evaporator sections include portions in the second region that are flush with the plane of the bottom surface at the second region, and all portions of the at least one condenser section are recessed below a plane of the bottom surface at the first region.
