A thermal transfer means comprising a flexible bag or pouch filled with a chemically inert, electrically nonconductive, nonflammable, essentially gas-free, thermally stable, thermally conductive, body of liquid comprising fluorochemical liquid. Said bag is fabricated from a flexible, durable plastic film that has low permeability to air and the fluorochemical liquid. The configuration of the bag is conformable to adapt to the geometry of the space, formed between the surface of a heat generating component or components and the surface of a heat sink, into which the bag is inserted, thereby contacting said surfaces and providing a thermal conduction path for heat generated by the heat generating component during operation from said component to the heat sink. The liquid has a boiling point such that it down not boil at the highest operating temperature of the device. Also provided is a method for making and filling the bag such that after sealing the bag is substantially gas free.
A sealed, flexible, liquid-containing thermal transfer bag adapted for placement in a heat generating device between and in intimate contact with a heat generating component and a heat dissipating surface such as a cold plate or housing to conduct heat from said component to said heat dissipating surface, said bag comprising:
