Publication number: 20030136551Abstract: A very thin flat plate shaped sintered copper powder wick with a waffle pattern on one surface is sealed between two sheets of thin copper foil. The interior space within the sealed foil is evacuated and charged with sufficient water to saturate the wick through a copper tube which is then hermetically sealed, producing the working core of a flat plate heat pipe. Heat treated aluminum sheets are bonded with thin, thermally conductive adhesive layers to both the evaporator and condenser surfaces of the copper foil heat pipe container. The resulting flat heat pipe is lighter in weight by about 40%, much more durable, and less expensive to fabricate than all-copper, machined container flat plate heat pipes, while high performance is maintained.Type: ApplicationFiled: November 14, 2002Publication date: July 24, 2003Inventor: Allan P. Bakke

Publication number: 20030136554Abstract: A fin louver design using breaking and reversal louvers whose lengths are substantially longer than the half-length of the main louver but at slightly lower angles to the fin face, in order to increase the heat transfer while reducing or minimizing the airside air pressure drop. The reversal louvers will not dramatically change the airflow direction but rather permit air to follow the louver direction, thus preventing any dead area where the air speed is approximately zero in the central part between the two reversal louvers. Contact is provided between fresh moving air and the central part between the two reversal louvers.Type: ApplicationFiled: January 24, 2002Publication date: July 24, 2003Applicant: VALEO ENGINE COOLING, INC.Inventors: Zaiqian Hu, Philippe Le Gauyer, Lei Fang

Publication number: 20030136556Abstract: This invention provides a tubing hanger system which permits isolation of the production tubing from the electrical power cable, thereby isolating the electrical power cable from high pressures encountered in the production tubing. Further, the tubing hanger system enables pressure testing of the integrity of both the production and cable seals, without requiring disassembly of any components of the tubing hanger assembly or damaging the electrical power cable, in advance of high pressure operations. Specifically, the invention provides a tubing hanger assembly for use in a tubing head of a production well, and which provides for passage of production fluids from the production tubing mounted therebelow, through a central bore in the tubing head and through the tubing hanger assembly, while also providing isolation of the production tubing from an electrical power cable passing through the tubing hanger assembly.Type: ApplicationFiled: January 18, 2002Publication date: July 24, 2003Inventors: Michael James Cornelssen, Keith David Farquharson
