| Abstract: | Systems and methods described herein are directed to rotary heat
exchangers configured to transfer heat to a heat transfer medium flowing
in substantially axial direction within the heat exchangers. Exemplary
heat exchangers include a heat conducting structure which is configured
to be in thermal contact with a thermal load or a thermal sink, and a
heat transfer structure rotatably coupled to the heat conducting
structure to form a gap region between the heat conducting structure and
the heat transfer structure, the heat transfer structure being configured
to rotate during operation of the device. In example devices heat may be
transferred across the gap region from a heated axial flow of the heat
transfer medium to a cool stationary heat conducting structure, or from a
heated stationary conducting structure to a cool axial flow of the heat
transfer medium. |
