Abstract
A method of and system for recovering a dielectric fluid used for immersion cooling of electronic devices, the method including filtering the dielectric fluid to remove a first group of solid contaminants; distilling the filtered dielectric fluid in one or more distillation tanks to produce a vaporized dielectric fluid; separating the vaporized dielectric fluid from less volatile contaminants, such that the vaporized dielectric fluid is introduced as a condensate into a circulation tank; circulating the condensate by pumping the condensate from the circulation tank through one or more filters; filtering the circulating condensate through the filter(s) to remove a second group of contaminants; and returning the filtered condensate to the circulation tank.
Claims9
A system for recovering a liquid dielectric used for immersion cooling of at least one electronic device, the system comprising:
- a first filter device comprising a first inlet, a first outlet, and a first filter located between the first inlet and the first outlet, the first filter capable of removing a first group of solid contaminants from the liquid dielectric as the liquid dielectric passes from the first inlet to the first outlet and through the first filter;
- a first distillation tank in fluid communication with the first filter device, the first distillation tank comprising a first heating element located at or near a bottom surface of the first distillation tank, the first heating element capable of heating the dielectric liquid to produce a first vaporized dielectric gas;
- a first fluid-cooled condensing device located within the first distillation tank and at or near a top surface of the first distillation tank, the first fluid-cooled condensing device capable of condensing the first vaporized dielectric gas to produce a first condensed dielectric liquid;
- a second distillation tank in fluid communication with the first distillation tank, the second distillation tank comprising a second heating element located at or near a bottom surface of the second distillation tank, the second heating element capable of heating the first condensed dielectric liquid to produce a second vaporized dielectric gas;
- a second fluid-cooled condensing device located within the second distillation tank and at or near a top surface of the second distillation tank, the second fluid-cooled condensing device capable of condensing the second vaporized dielectric gas to produce a second condensed dielectric liquid;
- and
- a filtration system in fluid communication with the second distillation tank and capable of receiving the second condensed dielectric liquid, the filtration system comprising:
- a second filter device comprising a second inlet, a second outlet, and a second filter located between the second inlet and the second outlet;
- a pump in fluid communication with the second outlet;
- and
- a circulation tank fluidly connected between the pump and the second inlet,
- wherein the second filter is capable of removing a second group of solid contaminants from the second condensed dielectric liquid as the second condensed dielectric liquid passes from the second inlet to the second outlet and through the second filter.
