Patent number: 9068775Abstract: A drying apparatus and method including heated airflow and ultrasonic transducers. The ultrasonic transducers are arranged and operated for effectively breaking down the boundary layer to increase the heat transfer rate. The ultrasonic transducers are spaced from the material to be dried a distance of about (?)(n/4), where ? is the wavelength of the ultrasonic oscillations and n is an odd integer (i.e., 1, 3, 5, 7, etc.). In this way, the amplitude of the ultrasonic oscillations is maximized to more-effectively agitate the boundary layer. In addition, the ultrasonic transducers are operated to produce about 120-190 dB (preferably, about 160-185 dB) at the interface surface of the material to be dried. In one embodiment, the ultrasonic transducers are of a pneumatic type. In another embodiment, the ultrasonic transducers are of an electric type. And in other embodiments, infrared and/or UV light devices are included for further boundary layer disruption.Type: GrantFiled: February 9, 2009Date of Patent: June 30, 2015Assignee: Heat Technologies, Inc.Inventor: Zinovy Plavnik

Patent number: 7284596Abstract: A heat removal system includes a heatsink assembly having a base and a plurality of heat conducting folded fin members projecting from a first surface of the base and arranged to leave an open space on the first surface of the base. At least one thermally conductive slug projects from the center of the folded fin members and the folded fin members are thermally coupled to the slug. A gas circulating system is disposed over the slug and fin members projecting from the first surface of the base. The sidewall of a fin may be provided with at least one aperture. The top surface of the fin is closed, thereby permitting the fin to operate as a plenum of sorts. The bottom of the troughs may also be closed. The fins/troughs act as a plenum. A method of producing the folded fin heatsink member is also described.Type: GrantFiled: November 26, 2003Date of Patent: October 23, 2007Assignee: Heat Technology, Inc.Inventor: Ralph I. Larson

Patent number: 6339875Abstract: A heatsink interface material for securing a heatsink to an integrated circuit includes a core material having an adhesive forced into opposing surfaces of the core material. It is preferred that an intermediate region of the core material be free of adhesive. In one embodiment, copper is deposited on the first and second surfaces of the core material and then nickel is deposited on the first and second surfaces. An exemplary method for fabricating a heatsink interface material in accordance with the present invention can include applying heat and pressure to force adhesive into the core material. Copper and nickel can be deposited on the core material surfaces using electroless deposition techniques.Type: GrantFiled: March 9, 2000Date of Patent: January 22, 2002Assignee: Heat Technology, Inc.Inventor: Ralph I.

Patent number: 5774336Abstract: A thermally efficient circuit board has a base layer with high thermal conductivity and a thermal expansion coefficient close to that of silicon, such as aluminum silicon carbide. Above the base layer is a layer of anodized metal, either a separate material, such as aluminum, which is formed on the base and then anodized, or an anodized portion of the base itself. To the anodized metal is then applied a sealant material of lower thermal conductivity, but good electrically insulative and adhesive qualities, such as Teflon FEP. The sealant flows into cavities in the porous anodized metal structure, creating a well-anchored bond. A metal foil layer is then bonded to the surface of the sealant, and used to pattern conductive circuit paths using conventional methods.Type: GrantFiled: September 13, 1996Date of Patent: June 30, 1998Assignee: Heat Technology, Inc.Inventor: Ralph I.

Patent number: 5622123Abstract: A process and apparatus for sterilizing soil includes an implement including a plurality of subsurface tools having hot water nozzles mounted thereon and connected to a source of hot water. Hot water is injected into the top layer of soil as the implement is moved over a field. Stirrer tools are mounted on the implement rearwardly of the subsurface tools and extend into the ground for mixing the soil and hot water to thereby provide a uniform temperature to the soil. A foam applying system applies an insulating foam to the surface of the soil immediately after the injection of hot water into the soil.Type: GrantFiled: August 10, 1995Date of Patent: April 22, 1997Assignee: Aqua Heat Technology, Inc.Inventor: A.H.J.
