Abstract:
A heat exchanger provides simplicity, compactness, and high efficiency through a construction that includes an elongated tube structure comprising three rows of flattened multiport tubing, with a first row of tubing and a third row of tubing sandwiching a second row of tubing. The second row of tubing terminates in opposite ends on which are received refrigerant fittings and respectively. The first and third rows of tubing each include a run abutting and in heat exchange relation with the tubing. Opposing ends of the tubing extend about refrigerant fittings and and are received in refrigerant fittings. The tubing includes parts and extending about the refrigerant fittings and and terminating in opposite ends. The ends are also in fluid communication with fittings.

A thermal management system for an electronic device is provided a first thermal energy transfer assembly that is thermally coupled between a heat generating structure located on a circuit card and a first thermal interface surface that is spaced away from the heat generating structure. A second thermal energy transfer assembly includes a second thermal interface surface which is arranged in confronting relation to the first thermal interface surface. A clamping mechanism is arranged to move the second thermal interface surface between (i) a first position that is spaced away from the first thermal interface surface, and (ii) a second position wherein the second thermal interface surface is pressed against the first thermal interface surface so as to allow the busing of thermal energy from the first thermal energy transfer assembly to the second thermal energy transfer assembly by heat transfer from the first thermal interface surface to the second thermal interface surface.

Abstract:
A flexible loop thermosyphon is provided having a flexible, hermetic, outer tube and a flexible, non-hermetic, inner tube, positioned concentrically within the outer tube, forming an annulus between the outer tube and inner tube. The annulus acts as a vapor conduit transferring vapor to the loop thermosyphon condenser while the inner tube acts as a condensate conduit returning liquid to the loop thermosyphon evaporator.
