Abstract
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.
