Heat transfer devices and methods of transfering heat

Abstract:

Heat transfer devices, electronic devices, and methods for heat transfer with an external body. Heat transfer devices include a first disc, a second disc positioned adjacent to the first disc, and at least one spacer positioned between the first disc and the second disc. The first disc defines an aperture and comprises a pin cooling structure extending from around the aperture. The pin cooling structure comprises a distal end configured to facilitate heat exchange between the pin cooling structure and an external/adjacent/separate body and one or more side walls. At least one of the one or more side walls, the distal end, and the aperture at least partially define a pin volume. The second disc defines an inlet that is configured to (i) receive a fluid, and (ii) allow the fluid to flow from the inlet and into the pin volume.
