Patent number: 8726508Abstract: A number of flat tubes, flat tube heat exchangers, and methods of manufacturing both are described and illustrated. The flat tubes can be constructed of one, two, or more pieces of sheet material. A profiled insert integral with the flat tube or constructed from another sheet of material can be used to define multiple flow channels through the flat tube. The flat tubes can be constructed of relatively thin material, and can be reinforced with folds of the flat tube material and/or of an insert in areas subject to higher pressure and thermal stresses. Also, the relatively thin flat tube material can have a corrosion layer enabling the material to resist failure due to corrosion. Heat exchangers having such flat tubes connected to collection tubes are also disclosed, as are manners in which such tubes can be provided with fins.Type: GrantFiled: January 19, 2007Date of Patent: May 20, 2014Assignee: Modine Manufacturing CompanyInventors: Werner Zobel, Jens Nies, Bernhard Stephan, Charles James Rogers, Thomas Feldhege

Patent number: 8561451Abstract: A system and method for producing flat tubes is described and illustrated. The flat tubes can be produced from at least one strip of endless band material having at least one wall part and an inner part formed with corrugations on a roller train provided with roller pairs, with the strip running in a longitudinal direction through the rollers and being shaped. The inner part of the flat tube can be formed with corrugations placed between the shaped wall parts, after which the closure of the flat tube is carried out. Production of the flat tubes can include forming spaced apart band thinning lines running in the longitudinal direction of the strip, and forming corrugation peaks and corrugation troughs at the band thinning lines.Type: GrantFiled: August 3, 2009Date of Patent: October 22, 2013Assignee: Modine Manufacturing CompanyInventors: Frank Opferkuch, Daniel Borst, Martin Ploppa, Werner Zobel, Jens Nies, Andreas Stolz, Dieter Merz, Siegfried Eisele

Patent number: 8261816Abstract: A heat exchanger with a plurality of stacked flat tubes and a collecting tank having a wall extending around the entire periphery of, and connected to, the end of the stacked flat tubes. A first medium may be distributed through the collecting tank and flat tubes. Internal inserts are in the flat tubes, with the inserts being bonded between the broad sides of the tubes and, in the region of connection of the tubes to the collecting tank, being configured to compensate for length changes in the stacking direction caused by temperature changes, as by recesses in connectors such as wave flanks or by corrugated wave flanks. The flat tubes with inserts such as described may be separately provided for use in manufacture of heat exchangers.Type: GrantFiled: December 17, 2004Date of Patent: September 11, 2012Assignee: Modine Manufacturing CompanyInventors: Peter Ambros, Jörg Soldner, Roland Strähle, Andreas Stolz, Dieter Merz, Jens Nies, Sven Thumm, Katja Müller, Harald Schatz, Peter C.

Publication number: 20100170668Abstract: The invention relates to a heat exchanger, such as, for example, a liquid cooler, charge air cooler or the like, having two-part collecting tanks which are composed entirely of plastic and have inlet or outlet connecting pipes. One collecting tank part can have openings for receiving the ends of tubes, with the tube ends being adhesively connected therein, and with the two collecting tank parts being welded to one another at a weld seam which runs around the periphery of their walls. The two tank parts form an oval to round collecting tank cross section between the tubes, and the weld seam is situated in a seam preparation which is formed as a thickened portion of the walls of the tank parts. As a result of the invention, the heat exchanger is of particularly pressure-resistant design and is very production-friendly.Type: ApplicationFiled: November 30, 2007Publication date: July 8, 2010Inventors: Jens Nies, Roland Strahle, Rainer Kasinger, Jochen Orso
