Abstract:
1. An apparatus, comprising heat-generating structure disposed in an environment having an ambient pressure, and a cooling system for removing heat from said heat-generating structure, said cooling system including: a fluid coolant; structure which reduces a pressure of said coolant to a subambient pressure at which said coolant has a boiling temperature less than a temperature of said heat-generating structure; and structure which directs a flow of said coolant in the form of a liquid at said subambient pressure in a manner causing said liquid coolant to be brought into thermal communication with said heat-generating structure, the heat from said heat-generating structure causing said liquid coolant to boil and vaporize, so that said coolant absorbs heat from said heat-generating structure as said coolant changes state.
