Apparatus for cooling with coolant at subambient pressure
First Claim
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.

Abstract
An apparatus includes heat-generating structure disposed in an environment having an ambient pressure, and a cooling system for removing heat from the heat-generating structure. The cooling system includes a fluid coolant, structure which reduces a pressure of the coolant to a subambient pressure at which the coolant has a boiling temperature less than a temperature of the heat-generating structure; and structure which directs a flow of the liquid coolant at the subambient pressure so that it is brought into thermal communication with the heat-generating structure, the coolant then absorbing heat and changing to a vapor.
