Patent number: 8397798Abstract: A two-phase heat transfer system includes an evaporator, a condenser, a vapor line, and a liquid return line. The evaporator includes a liquid inlet, a vapor outlet, and a capillary wick having a first surface adjacent the liquid inlet and a second surface adjacent the vapor outlet. The condenser includes a vapor inlet and a liquid outlet. The vapor line provides fluid communication between the vapor outlet and the vapor inlet. The liquid return line provides fluid communication between the liquid outlet and the liquid inlet. The wick is substantially free of back-conduction of energy from the second surface to the first surface due to an increase in a conduction path from the second surface to the first surface and due to suppression of nucleation of a working fluid from the second surface to the first surface to promote liquid superheat tolerance in the wick.Type: GrantFiled: June 28, 2005Date of Patent: March 19, 2013Assignee: Alliant Techsystems Inc.Inventors: Edward J. Kroliczek, Kimberly R. Wrenn, David A. Wolf, Sr.

Patent number: 8360139Abstract: A ceramic heat exchanger includes a heat exchange section that heat-exchanges between two fluids A and B flowing opposite directions to each other. The heat exchange section includes ceramic blocks stacked one on top of another with a seal therebetween. The ceramic blocks have a plurality of parallel lines of flow channels, each line defined by the flow channels through which the same fluid flows, any two adjacent lines being defined by the flow channels through which the different fluids A and B flow respectively. Both ends in the stacking direction of the stack are bound to join and integrate the ceramic blocks with tightening means including end plates and a tie rod. A thermal expansion absorber is disposed on an external surface of the end plates for absorbing thermal expansion in the axial direction of the tie rod.Type: GrantFiled: May 12, 2006Date of Patent: January 29, 2013Assignees: Kabushiki Kaisha Toshiba, Japan Atomic Energy AgencyInventors: Takanari Inatomi, Yasuhiro Sakai, Shigeki Maruyama, Shoko Suyama, Ryutaro Hino, Atsuhiko Terada, Kaoru Onuki, Shinji Kubo, Seiji Kasahara

Patent number: 8349470Abstract: The exemplary embodiments relate to a multilayer aluminum alloy sheet material suitable for fabrication into coolant-conveying tubes, headers and the like used for heat exchangers, and to the tubes and headers, etc., fabricated from the sheet. The multi-layer metal sheet has a core layer of aluminum alloy having first and second sides. The first side has an interlayer made of a Zn-containing aluminum alloy positioned between a Zn-containing outer layer and the core layer. The alloy of the outer layer is more electronegative than the alloy of the interlayer. The alloy of the interlayer is preferably more electronegative than the alloy of the core layer. The first side clad in this way is the side intended for exposure to the coolant, and provides good resistance to corrosion and erosion.Type: GrantFiled: December 17, 2009Date of Patent: January 8, 2013Assignee: Novelis Inc.Inventors: Pierre Henri Marois, Kevin Michael Gatenby, Thomas L. Davisson, Andrew D. Howells, Ian Smith

Patent number: 8343635Abstract: Provided is a multi-layered sheet which has undergone heating corresponding to brazing, such as an aluminum-alloy radiator tube, or a multi-layered sheet such as an aluminum-alloy brazing sheet. The multi-layered sheet can have a reduced thickness and has excellent fatigue properties. The multi-layered sheet of aluminum alloys comprises a core layer (2) which has been clad at least with a sacrificial layer (3). This multi-layered sheet is a multi-layered sheet to be subjected to brazing or welding to produce a heat exchanger or is a multi-layered sheet which has undergone heating corresponding to brazing. The core layer (2) comprises a specific 3000-series composition. In this core layer (2), the average density in number of dispersed particles having a specific size has been regulated. As a result, fatigue properties, which govern cracking, can be highly improved.Type: GrantFiled: February 5, 2009Date of Patent: January 1, 2013Assignee: Kobe Steel, Ltd.Inventors: Katsushi Matsumoto, Eiichi Tamura, Masao Kinefuchi, Toshiki Ueda, Fumihiro Koshigoe, Shimpei Kimura
