Abstract:
1. A cooling apparatus comprising: a housing at least partially surrounding and forming a fluid-tight compartment about at least one electronic component; a boiling fluid mixture comprising a first dielectric fluid and a second dielectric fluid disposed within the fluid-tight compartment, the at least one electronic component being immersed within the boiling fluid mixture; a condensing fluid disposed within the fluid-tight compartment, the condensing fluid and the boiling fluid mixture being immiscible, and the condensing fluid comprising a lower specific gravity than that of the boiling fluid mixture, and a higher thermal conductivity than that of the boiling fluid mixture, and wherein the condensing fluid facilitates condensing of vaporized boiling fluid mixture within the fluid-tight compartment; and a cooling structure disposed within the fluid-tight compartment, the cooling structure comprising a condensing region and a sub-cooling region, the condensing region being in contact with the condensing fluid, and the sub-cooling region being in contact with the boiling fluid mixture, wherein the cooling structure facilitates heat removal from the fluid-tight compartment.
