Abstract

Electronic components are mounted upon a chassis which slides vertically inside a tank. The components are normally cooled by circulating transformer oil around them. When inspection, maintenance or repair work is required, the bottom of the chassis is sealed to the side of the tank, an opening in the bottom of the chassis is closed and the chassis elevated by pumping the transformer oil beneath the chassis bottom.
