Patent number: 9080818Abstract: Heat exchangers are described that employ fins made of a heat conducting foam material to enhance heat transfer. The foam fins can be used in any type of heat exchanger including, but not limited to, a plate-fin heat exchanger, a plate-frame heat exchanger or a shell-and-tube heat exchanger. The heat exchangers employing foam fins described herein are highly efficient, inexpensive to build, and corrosion resistant. The described heat exchangers can be used in a variety of applications, including but not limited to, low thermal driving force applications, power generation applications, and non-power generation applications such as refrigeration and cryogenics. The fins can be made from any thermally conductive foam material including, but not limited to, graphite foam or metal foam.Type: GrantFiled: February 3, 2012Date of Patent: July 14, 2015Assignee: Lockheed Martin CorporationInventors: Scott M. Maurer, Nicholas J. Nagurny, Michael R. Eller, James W. Klett

Patent number: 9062634Abstract: An EGR cooler core has multiple tubes for conveying engine exhaust gas. Tube inlets are joined to a flat inlet header plate at tube/header plate joints in a flat zone of the inlet header plate. An endless groove in the inlet header plate circumscribes the joints while reducing a constant nominal thickness of the header plate in the flat zone along the groove without creating an opening through the header plate. This gives some compliance to the flat zone for mitigation of stresses induced by tube growth.Type: GrantFiled: April 8, 2014Date of Patent: June 23, 2015Assignee: Internaitonal Engine Intellectual Property Company, LLCInventors: Shouhao Wu, Robert Lawrence Rowells

Publication number: 20150083365Abstract: A steam generator includes a tube bundle having a plurality of tubes, arranged in rows and columns. The first column of tubes includes a first tube having a curved center line disposed in a first plane. The second column of tubes includes a second tube having a curved center line disposed in a second plane, the second plane being parallel to and spaced a distance from the first plane. The steam generator further includes a first number of solid anti-vibration bars disposed between the first column of tubes and the second column of tubes; wherein each of the tubes has a tube outer diameter; and wherein each of the first number of anti-vibration bars has a thickness generally transverse to the first and second planes, the thickness being greater than the distance between the first and second planes minus the tube outer diameter.Type: ApplicationFiled: September 25, 2013Publication date: March 26, 2015Applicant: Westinghouse Electric Company LLCInventors: PADMANABHA J.

Patent number: 8978740Abstract: A heat exchanger includes a bundle of tubes, which can be inserted into a tubular housing. Exhaust gas can flow through the tubes. A coolant duct can be arranged between the tubes. The bundle of tubes can have at least one grid-like securing structure which supports the bundle in the housing. The behavior of the heat exchanger with respect to vibrations is affected by outwardly curved metallic springs attached to the bundle of tubes which may be deformed in the opposite direction to the insertion direction of the bundle into the housing. The spring force is directed against the housing in order to dampen vibrations. The heat exchanger can also include an elastic device for permitting a change in length caused by temperature changes.Type: GrantFiled: October 1, 2010Date of Patent: March 17, 2015Assignee: Modine Manufacturing CompanyInventors: Harald Schatz, Stefan Muller-Lufft, Ingo Heitel, Omur Acar, Jorg Soldner, Michael Daniel, Bjorn Volquardsen, Joel T.
