Patent number: 9644869Abstract: According to one embodiment, a cooling system for heat-generating structures comprises a cooling loop and a heat exchanger. The cooling loop directs a flow of a fluid coolant to both an active heat-generating structure and an inactive heat-generating structure. The fluid coolant receiving thermal energy from the active heat-generating structure and transfers thermal energy to the inactive heat-generating structure when a temperature of the fluid coolant is greater than an ambient temperature of an environment surrounding the heat-generating structures. The active heat-generating structure is operable to switch to an inactive state and the inactive heat-generating structure is operable to switch to an active state. The heat exchanger is in thermal communication with the first and second heat-generating structures and is operable to receive the fluid coolant at a first temperature and dispense of the fluid coolant out of the heat exchanger at a second temperature.Type: GrantFiled: October 25, 2007Date of Patent: May 9, 2017Assignee: RAYTHEON COMPANYInventors: Richard M.

Patent number: 8490418Abstract: According to one embodiment of the invention, a method is provided for cooling heat-generating structure disposed in an environment having an ambient pressure. The heat-generating structure includes electronics. The method includes providing a coolant, reducing 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 bringing the heat-generating structure and the coolant at the subambient pressure into contact with one another, so that the coolant boils and vaporizes to thereby absorb heat from the heat-generating structure. In a more particular embodiment the coolant is either pure water or pure methanol with an electrical resistivity level of greater than one million Ohms-cm. Further, in another particular embodiment the method includes filtering the coolant to maintain its purity above a particular level.Type: GrantFiled: March 9, 2011Date of Patent: July 23, 2013Assignee: Raytheon CompanyInventors: Richard M.

Patent number: 7921655Abstract: According to one embodiment of the disclosure, a cooling system for a heat-generating structure comprises a heat exchanger, a first structure, a condenser heat exchanger, and a second condenser. The heat exchanger is in thermal communication with a heat-generating structure. The heat exchanger has an inlet and an outlet. The inlet is operable to receive fluid coolant substantially in the form of a liquid into the heat exchanger, and the outlet is operable to dispense fluid coolant at least partially in the form of a vapor out of the heat exchanger. The first structure directs a flow of the fluid coolant substantially in the form of a liquid to the heat exchanger. Thermal energy communicated from the heat-generating structure to the fluid coolant causes the fluid coolant substantially in the form of a liquid to boil and vaporize in the heat exchanger.Type: GrantFiled: September 21, 2007Date of Patent: April 12, 2011Assignee: Raytheon CompanyInventors: William G.
