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: 8667686Abstract: A method for producing tubes for use in a heat exchanger that includes providing first and second metallic strips on a rolling mill train with predetermined breaking points using a device, deforming the strips to form the a tube, separating individual tubes from the tube at the predetermined breaking points, sensing positions of the predetermined breaking points in the strips using a sensing element which the strips pass through, transmitting signals relating to sensed positions of the predetermined breaking points of the strips to a computer, comparing the positions of the predetermined breaking points in the first and the second strips using the computer on the basis of the signals transmitted, and sending signals to the device using the computer which lead to the alignment of the positions of the predetermined breaking points in the first and the second strips.Type: GrantFiled: August 5, 2010Date of Patent: March 11, 2014Assignee: Modine Manufacturing CompanyInventor: Werner Zobel

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
