Abstract
A heat transfer bag especially useful for cooling electronic components is made of a flexible sheet of material and is filled with a fluorochemical heat transfer liquid. A metallic thermal via extends through a hole in the bag for direct contact with an external surface of a heat-generating component. A portion of the via extends into the bag and functions as a heat radiating fin to enhance the transfer of heat from the component to the liquid within the bag.
