In one embodiment heat transfer and distribution mechanism customized to the application requirements of a greenhouse heating batch-type process is disclosed, along with a recipe for a readily available biomass material composition that will slowly decompose while it generates a substantial quantity of usable heat energy to be consumed in the elevation of temperature in a separated greenhouse basement confinement area.Type: GrantFiled: July 8, 2002Date of Patent: November 14, 2006Inventor: Joseph P. Ouellette

Patent number: 7106589Abstract: A heat sink, method of making a heat sink, and a heat sink assembly. The heat sink includes a base and a plurality of heat pipes that extend from the base. The base is dimensioned and shaped to promote good thermal contact with the heat source, and the heat pipes are attached thereto in such a manner as to promote good thermal contact to the working fluid. Each heat pipe includes an outer surface and an inner surface that form a condenser portion from which from heat is transferred during condensation of the working fluid.Type: GrantFiled: May 17, 2004Date of Patent: September 12, 2006Assignee: AALL Power Heatsinks, Inc.Inventors: Richard F. Kiley, Simone Bush

Patent number: 7013954Abstract: A thermosiphon which can be manufactured easily at low costs, having excellent resistance to pressure, without the circulation of a working fluid being hindered. A condenser 3 includes a condensing section 4 composed of extruded members in which a plurality of fine pores 7 are formed, a branching section 5 provided on an upstream side of the fine pores 7 to supply a gaseous working fluid returned from a gas pipe 12 into each of the fine pores 7, and a collecting section 6 provided on a downstream side of the fine pores 7 to collect the working fluid condensed inside the fine pores 7 and then supply the same into a liquid pipe 9. The gas pipe 12 is connected to an upper portion of the branching section 5 and the liquid pipe 9 is connected to a lower portion of the collecting section 6.Type: GrantFiled: November 4, 2003Date of Patent: March 21, 2006Assignee: Twinbird CorporationInventor: Kazuya Sone

Patent number: 6979939Abstract: The present invention relates to a cooling device for an electron tube designated to amplify a high frequency signal. The invention is particularly suitable for cooling electron tubes that amplify radio frequency signals used for television or radio. The electron tube installed on a portal frame designed to hold the frame. The device includes a first hydraulic circuit inside which a first fluid circulates to cool at least part of the tube. The device also includes fluid exchanger to transfer heat transported by the first fluid to a second hydraulic circuit. The exchanger is also located on the portal frame.Type: GrantFiled: April 1, 2003Date of Patent: December 27, 2005Assignee: ThalesInventors: Michel Langlois, James McVea, Jean-François Houdard

Patent number: 6942015Abstract: A body heating/cooling apparatus includes a vest having a front panel and a back panel defining a cavity therebetween. A flexible, continuous channel is disposed in serpentine fashion throughout the cavity and has adjacent portions. An inlet and an outlet are provided for infusing a fluid into the channel and for withdrawing the fluid from the channel. The adjacent portions of the channel are placed in fluid communication by passageways extending between corresponding adjacent portions at locations intermediate the ends of the adjacent portions. The passageways are configured with respect to the corresponding adjacent portions such that substantially all of a fluid flowing through the corresponding adjacent portions normally bypasses the passageways.Type: GrantFiled: October 5, 2000Date of Patent: September 13, 2005Assignee: Jenkins Comfort Systems, LLCInventor: Donny Ray Jenkins

Patent number: 6923249Abstract: A passive thermal control system maintains the operating temperature range of protected equipment within desired limits by controlling the conductive attributes of thermal interfaces and physical relationships within the system so as to achieve a desired thermal balance. In one embodiment, an integrated cell unit (100) includes a solar array (102), a Lithium ion cell (108) and an antenna assembly (114) such as a phased array antenna. In operation, a thermal gradient (116) is defined between the array (102) and the assembly (114) as the assembly (114) radiates heat from the array (102) into space. The operating temperature range of the cell (108) is controlled by appropriate design of the thermal interfaces between the cell (108) and the assembly (114) and/or interfaces within the assembly (114), such as a thermal interface associated with dielectric spacers provided between emitter pairs of the assembly (114).Type: GrantFiled: May 28, 2003Date of Patent: August 2, 2005Assignee: Lockheed Martin CorporationInventors: Harry H. Porter, Jose Valenzuela, James D. Williams, Timothy W. Harvey
