Electronic cooling

Claim 2

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.

Claim 3

The invention as defined in claim 1 further comprising: j. raising and lowering of the chasis by k. opening and closing a hole in the chassis bottom.

Claim 4

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.

Claim 5

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.

Claim 6

The invention as defined in claim 3 further comprising: n. said valve attached to a valve operator which extends to the top of the chassis.

Claim 7

The invention as defined in claim 3 further comprising: n. a space at the top of the chassis not submerged by liquid for non-submergible electronic components.

Claim 8

The invention as defined in claim 3 further comprising: n. a hole in the chassis, o. a back valve in said hole so that normally the flow of cooling liquid is over the components, p. said back valve connected to said bottom valve so that as one is closed the other is opened.

Claim 9

The invention as defined in claim 3 further comprising n. said chassis fitting snuggly within said tank thereby guiding the chassis as it is elevated within the tank.

Claim 10

The invention as defined in claim 7 further comprising: o. said valve attached to a valve operator which extends to the top of the chassis.

Claim 11

The invention as defined in claim 8 further comprising: p. a space at the top of the chassis not submerged by liquid for non-submergible electronic components.

Claim 12

The invention as defined in claim 9 further comprising: q. a hole in the chassis, r. a back valve in said hole so that normally the flow of cooling liquid is over the components, p. said back valve connected together so that as one is closed the other is opened.
