Publication number: 20070163754Abstract: The invention relates to an improved thermosiphon and to a method for transferring heat. The thermosiphon has a higher efficiency than existing thermosiphons because it does not rely on a pool-boiling evaporator but rather uses a forced-convection boiling evaporator.

The fluid in its liquid phase enters the evaporator from its inlet in its upper portion and, by gravity, flows down the piping network of the evaporator, clinging on the inner surface of the tubes of the piping network. As the liquid flows down, it evaporates such that the fluid at the bottom of the evaporator is predominantly in a gaseous phase. The fluid in gaseous phase is then returned to the condenser.Type: ApplicationFiled: January 19, 2006Publication date: July 19, 2007Inventors: Jean-Pierre Dionne, Antonio Lagana

Preferably, the surface areas are formed by the surfaces of bands of copper, of a copper alloy or of a copper compound extending essentially in a direction transverse to the direction of flow.Type: ApplicationFiled: April 29, 2005Publication date: July 19, 2007Inventor: Urs Studer

Publication number: 20070163764Abstract: A heat exchanger including plate fins and, the tubes fins being stacked at respective intervals relative to one another, and heat exchanger tubes penetrating the fins in a fin-stacking direction. The heat exchanger exchanges heat between fluids flowing, respectively, inside and outside the heat exchanger tubes, through the heat exchanger tubes and the fins. Each of the fins includes cut-raised portions with a bridge shape having leg and beam segments. The cut-raised portions associated with each of the heat exchanger tubes are located substantially only in a region of the fin satisfying Ws=(1??)Dp+?D ?>0.5, where Ws is spread width of the cut-raised portions in a direction (column direction) extending along an end of the fin on the upstream side of the second fluid, and D is outer diameter of the heat exchanger tube. Dp is alignment pitch of the heat exchanger tubes in the column direction.Type: ApplicationFiled: May 21, 2004Publication date: July 19, 2007Inventors: Kunihiko Kaga, Shinji Nakadeguchi, Akira Ishibashi, Shinichi Wakamoto, Toshinori Ohte, Hiroki Murakami, Tadashi Saito

Publication number: 20070163768Abstract: A core structure includes a plurality of flat tubes and a plurality of corrugated inner fins. Each corrugated inner fin has top portions for being fixed to an inner surface of an upper wall portion of the tubes, bottom portions for being fixed to an inner surface of a lower wall portion thereof, and slanted portions for connecting the top portion with adjacent bottom portions thereof. The corrugated inner fin has first corrugations located at both end sides of the corrugated inner fin and second corrugations located between the first corrugations, where the first and the second corrugations has the top portion and the adjacent slanted portions and project from the bottom portions. The first corrugations are set to be smaller in a front-back directional length of the corrugated inner fin than a front-back directional length of the second corrugations.Type: ApplicationFiled: December 26, 2006Publication date: July 19, 2007Inventor: Masayoshi Shinhama

Publication number: 20070163769Abstract: A method for providing for thermal conduction using an array of carbon nanotubes (CNTs). An array of vertically oriented CNTs is grown on a substrate having high thermal conductivity, and interstitial regions between adjacent CNTs in the array are partly or wholly filled with a filler material having a high thermal conductivity so that at least one end of each CNT is exposed. The exposed end of each CNT is pressed against a surface of an object from which heat is to be removed. The CNT-filler composite adjacent to the substrate provides improved mechanical strength to anchor CNTs in place and also serves as a heat spreader to improve diffusion of heat flux from the smaller volume (CNTs) to a larger heat sink.Type: ApplicationFiled: April 13, 2004Publication date: July 19, 2007Inventors: Jun Li, Meyya Meyyappan, Carlos Dangelo

Publication number: 20070163771Abstract: An air-conditioning device and an air conditioning method make it possible to reduce the problem that, on entry in a tunnel with a warm internal temperature, in the case of otherwise cold outside temperatures as a result of which, inter alia, the vehicle windowpanes and exterior mirror surfaces are cooled, this cold windowpane and exterior mirror surfaces, the surface temperature of which is lower than the dew-point temperature of the warm air in the tunnel interior, immediately fog up, since the absolute humidity on the surface then corresponds to more than 100% relative humidity. The air-conditioning device according to the invention and the air-conditioning method according to the invention use data supplied by already existing sensors and relating to the ambient weather, for example temperature data from an outside temperature sensor and moisture data from a dew-point sensor, in order to detect weather which is critical to this fogging.Type: ApplicationFiled: March 27, 2004Publication date: July 19, 2007Inventor: Wolfgang Straub

Publication number: 20070163772Abstract: An automotive air conditioning system is disclosed comprising an evaporative cooler in series with the conventional vapor compression system. The evaporative cooler comprises an array of dry channels and a contiguous array of wet channels. The primary air stream to be conditioned by the evaporator of the conventional air conditioning system is preconditioned by the evaporative cooler by lowering its dry bulb temperature without changing its absolute humidity. An evaporator core is supported downstream of the evaporative cooler for receiving the primary air from the dry channels and thereby produces liquid condensate. The system is distinguished by conducting the liquid condensate from the evaporator core to the wicking tank for use in the wet channels of the evaporative cooler.Type: ApplicationFiled: January 18, 2006Publication date: July 19, 2007Inventors: Mohinder Bhatti, Ilya Reyzin, Kurt Hollasch
