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.
Claims10
The process of cooling an electronic device having
- a. a tank having
- (i) a bottom,
- (ii) sides, and
- (iii) a top,
- (iv) with a uniform cross section configuration between the bottom and top,
- b. said top opening from said tank,
- c. a chassis within the tank,
- d. electronic components mounted on said chassis,
- e. cooling liquid at least partially filling said tank,
- f. a circulating pump fluidly attached to the tank, and liquid circulating from the upper portion of the tank through a heat exchanger and returned to the bottom of the tank,
- wherein the improved method comprises the following steps:
- g. sealing the bottom of the chassis to the sides of the tank, and
- h. pumping cooling liquid beneath the bottom of the chassis.

In an electronic device having
- a. a tank including
- (i) a bottom,
- (ii) sides, and
- (iii) a top,
- (iv) with a uniform corss section configuration between the bottom and top,
- b. said top opening from said tank,
- c. a chassis within the tank,
- d. electronic components mounted on said chassis,
- e. cooling liquid at least partially filling said tank,
- f. a circulating pump fluidly attached to the tank, and liquid circulating from the upper portion of the tank through a heat exchanger and returned to the bottom of the tank,
- wherein the improvement comprises:
- g. said chassis having a bottom thereon,
- h. seal means between the chassis bottom and the sides of the tank preventing the liquid from going from below the chassis bottom to above the chassis bottom,
- j. a hold through the chassis bottom,
- k. a bottom valve in said hole,
- m. whereby closing the hole by the valve causes fluid from beneath the chassis bottom to elevate the chassis.
