Publication number: 20080028787Abstract: An adsorption type heat exchanger includes a heat exchange part, in which a thermal medium circulates, and adsorbents made of particles. The adsorbents are fixed on an outer surface of the heat exchange part, to adsorb refrigerant vapor when a temperature of the thermal medium is low, and to desorb the adsorbed refrigerant vapor when the temperature of the thermal medium is high. In addition, percents of the adsorbents having particle sizes about in a range from 0 to 42 ?m are about 90% and over of the whole adsorbents.Type: ApplicationFiled: July 31, 2007Publication date: February 7, 2008Applicant: DENSO CorporationInventors: Hiroshi Mieda, Seiji Inoue, Satoshi Inoue, Hisao Nagashima, Masaaki Tanaka

Patent number: 7291271Abstract: The invention provides a non-cyclic, meso-frequency traveling wave electro-kinetic system capable of use in purification/separation and/or refrigeration/heat pump processes. In particular, the invention provides an adsorption system that can be used for fine or bulk chemical separations of liquid and gaseous materials. Similarly, the adsorption system can be readily adapted to function as a refrigeration/heat pump unit for use in heating and cooling systems. This reusable adsorption system provides high efficiency purification and/or cooling/heating with low energy demands and no moving parts. The invention can function in parallel or in series with other similar such adsorption units (though it can also operate as a single unit).Type: GrantFiled: December 9, 2003Date of Patent: November 6, 2007Assignee: Separation Design Group, LLCInventor: S. Douglas Galbraith

Patent number: 7285753Abstract: For use on board a mobile means of transport (eg. aircraft, bus, ship), a heating system and method are described which lead to a reduction of peak demand in the on-board kitchen energy supply system relating to the integrated heating appliances for the warming or heating of food. For this, latent or thermochemical heat storage units are used which are fully integrated into the structural elements of the heating appliance in question and heats the product in such a way that there is sufficient heat output, while at the same time, the absolute temperature is limited by means of an appropriate choice of heat storage material for product enhancement.Type: GrantFiled: December 13, 2004Date of Patent: October 23, 2007Assignee: Airbus Deutschland GmbHInventors: Merle Hoehne, Joachim Hoehne, Hans-Juergen Heinrich

Patent number: 7282799Abstract: An interface is formed by pressing a patterned first surface and a second surface together, with a particle-loaded interface material in between. The first surface is fabricated with a pattern of channels designed to redistribute the velocity gradients that occur in the interface material during interface formation in order to control the arrangement, orientation and concentration of particles at the end of the interface formation. The concept finds application in thermal interfaces and controlled placement of nano and micro particles and biological molecules.Type: GrantFiled: May 19, 2006Date of Patent: October 16, 2007Assignee: International Business Machines CorporationInventors: Thomas J. Brunschwiler, Urs Kloter, Ryan Joesph Linderman, Bruno Michel, Hugo E. Rothuizen

Publication number: 20070163753Abstract: A device such as a cooling fan drive for a motor vehicle engine has first and second members that are relatively moveable at a differential velocity. A liquid fills space separating relatively moving confronting surfaces of the respective members. The viscosity of the liquid enables the liquid to serve as a motion transmitting medium from one member to the other. Heat is generated within the liquid by shearing stress created by the relative movement of the members at a differential velocity with at least some of the generated heat being dissipated by conduction from at least one of the members through its surface. The viscous liquid comprises a nanoparticle-free base liquid to which have been added nanoparticles in an amount sufficient to measurably increase the thermal conductivity of the liquid filling the space over that of the base liquid.Type: ApplicationFiled: January 17, 2007Publication date: July 19, 2007Inventor: Gary D. Cochran

Patent number: 7157019Abstract: A process for producing a carbon foam heat sink is disclosed which obviates the need for conventional oxidative stabilization. The process employs mesophase or isotropic pitch and a simplified process using a single mold. The foam has a relatively uniform distribution of pore sizes and a highly aligned graphic structure in the struts. The foam material can be made into a composite which is useful in high temperature sandwich panels for both thermal and structural applications. The foam is encased and filled with a phase change material to provide a very efficient heat sink device.Type: GrantFiled: September 17, 2002Date of Patent: January 2, 2007Assignee: UT-Battelle, LLCInventors: James W.
