A heat exchanger apparatus for electrical components submerged in a dielectric liquid includes a closed main chamber for holding the liquid and a non-condensible gas above the liquid. A closed blockage chamber is positioned within the main chamber in contact with the dielectric. The blockage chamber holds non-condensible gas and segregates the gas and vapors of the liquid formed during operation of the heat exchanger. The side walls of the chambers are spaced from each other to form a narrow condensation and segregating duct within which the vapors of the liquid rise and condense. An orifice is provided in the closed blockage chamber near the top thereof. The orifice is sized to allow entry into the blockage chamber of the non-condensible gas as the gas is swept up the duct but to inhibit entry of the liquid should the apparatus be inverted or experience zero gravity forces.

An attitude insensitive heat exchanger apparatus for heat liberating components in thermal communication with a dielectric liquid, comprising: means defining a main chamber for holding said dielectric liquid and non-condensible gas above said liquid; condenser means associated with said chamber to receive a dielectric liquid vapor generated by cooperation of said dielectric liquid and said heat liberating components means defining a storage tank; and means cooperating with said non-condensible gas and an interior region of said tank to thereby ensure that non-condensible gas displaced by said dielectric liquid vapor is in fluid communication with said interior region of said storage tank and to ensure that said interior of said storage tank is fluidly isolated from said dielectric liquid, thereby providing a heat exchanger apparatus that is insensitive to changes in the attitude of said heat exchanger and the dielectric liquid therein.
