A liquid cooled heat exchanger includes first and second heat exchange chambers that are in thermal communication. The first heat exchange chamber is downstream of the second heat exchanges chamber and receives heat from a heat generating device, such as an electronic circuit. Heat in the first heat exchange chamber can be transferred to the second heat exchange chamber to increase the temperature of a subcooled liquid working fluid in the second heat exchange chamber. This can render a pressure drop across the heat exchanger that is relatively insensitive to a fraction of liquid that is vaporized in the first heat exchange chamber.

Liquid cooled heat exchanger

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.
