<p>According to one embodiment of the invention, a method for cooling heat-generating structure disposed in an environment having an ambient pressure includes providing a fluid refrigerant and reducing (22) a pressure of the refrigerant to a first sub-ambient pressure at which the refrigerant has a boiling temperature less than a temperature of the heat-generating structure (12). The method also includes bringing the refrigerant at the first sub-ambient pressure into thermal communication with the heat-generating structure (12), so that the refrigerant boils and vaporizes to thereby absorb heat from the heat-generating structure. The method further includes increasing (14) a pressure of the vaporized refrigerant above the first sub-ambient pressure to a second sub-ambient pressure.</p> |
