Abstract
A hermetically sealed vaporization chamber contains a vaporization cooled transformer to be cooled while dielectrically protected and two phase dielectric fluid comprising a liquid and a vapor. The transformer includes a plurality of cooling ducts extending vertically therethrough. The liquid, which resides at a bottom portion of the chamber and has a liquid level above the bottom of the chamber, is also distributed as a film which coats the top and the wall surfaces of the vertical ducts. A distribution pan with an outer rim is positioned above the transformer for receiving liquid condensate from said condenser. The rim portion of the distribution pan is provided with a plurality of apertures to distribute the liquid condensate uniformly as a film over the wall surfaces of the associated vertical ducts. At least one condensate make-up pump is provided for pumping liquid from the bottom portion of the chamber to the distribution pan.
