Abstract

A heat transfer device such as a heat sink includes one or more fins for dissipating heat received from a heat source, such as an integrated circuit or other electronic component. A thermosiphon component including a tube that defines a closed, continuous loop and contains a working fluid is attached to a face of a corresponding fin and is arranged to operate as a two-phase thermosiphon to transfer heat across areas of the fin. The heat transfer may equalize temperatures across the fin, enhancing efficiency.
