Patent number: 8371134Abstract: The subject invention pertains to a method and apparatus for cooling. In a specific embodiment, the subject invention relates to a lightweight, compact, reliable, and efficient cooling system. The subject system can provide heat stress relief to individuals operating under, for example, hazardous conditions, or in elevated temperatures, while wearing protective clothing. The subject invention also relates to a condenser for transferring heat from a refrigerant to an external fluid in thermal contact with the condenser. The subject condenser can have a heat transfer surface and can be designed for an external fluid, such as air, to flow across the heat transfer surface and allow the transfer of heat from heat transfer surface to the external fluid. In a specific embodiment, the flow of the external fluid is parallel to the heat transfer surface.Type: GrantFiled: June 30, 2009Date of Patent: February 12, 2013Assignee: Rini Technologies, Inc.Inventors: Daniel P. Rini, Louis Chow, H. Randolph Anderson, Jayanta Sankar Kapat, Bradley Carman, Brian Gulliver, Jose Mauricio Recio

Patent number: 8104533Abstract: The subject invention pertains to a spray nozzle apparatus and method of use. The subject spray nozzle can be used to spray atomized fluid. The atomized fluid can then be incident on a heated surface such that heat is transferred from the heated surface to the atomized fluid. The subject invention also relates to a spray-cooling system and method of use. The subject spray-cooling system can incorporate a spray nozzle and a heat transfer plate. A device to be cooled, such as a laser diode, microwave amplifier, or other high power electrical device, can be placed in direct thermal contact with the heat transfer plate. The spray from the spray nozzle can then be sprayed onto the heat transfer plate. In a specific embodiment, a cellular transfer plate can be used and the spray from the spray nozzle can be sprayed into a cellular cavity or compartment, within the heat transfer plate. Heat is transferred from the heat source to the sprayed liquid via the wall of the heat transfer plate.Type: GrantFiled: September 24, 2008Date of Patent: January 31, 2012Assignee: Rini Technologies, Inc.Inventors: Daniel P.

Patent number: 7921664Abstract: The subject invention pertains to a method and apparatus for high heat flux heat transfer. The subject invention can be utilized to transfer heat from a heat source to a coolant such that the transferred heat can be effectively transported to another location. Examples of heat sources from which heat can be transferred from include, for example, fluids and surfaces. The coolant to which the heat is transferred can be sprayed onto a surface which is in thermal contact with the heat source, such that the coolant sprayed onto the surface in thermal contact with the heat absorbs heat from the surface and carries the absorbed heat away as the coolant leaves the surface. The surface can be, for example, the surface of an interface plate in thermal contact with the heat source or a surface integral with the heat source. The coolant sprayed onto the surface can initially be a liquid and remain a liquid after absorbing the heat, or can in part or in whole be converted to a gas or vapor after absorbing the heat.Type: GrantFiled: March 11, 2008Date of Patent: April 12, 2011Assignee: Rini Technologies, Inc.Inventors: Daniel P.
