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: 6164909Abstract: The invention concerns a radial fan (1), especially as a fan for the cooling unit (2) of a vehicle. The fan includes an impeller (3) with radial blades (4), a cover disc (5) designed nozzle-like, and an air guide ring (6), as well as a stationary inflow nozzle (8). An axial air gap (10) is provided between the cover disc (5) and the co-rotating air guide ring (6).Type: GrantFiled: December 3, 1998Date of Patent: December 26, 2000Assignee: Modine Manufacturing CompanyInventors: Michael Ehlers, Bernhard Stephan

Patent number: 6056043Abstract: An accumulator (20) operating according to the layered storage principle is used in connection with the cooling loop of a vehicle, and includes charge alternation devices (34, 38) adapted to upper and lower storage regions (26, 28). The inflow and outflow velocity of the coolant should be between 0.1 and 0.5 m/s, and charging or discharging of the accumulator (20) should occur within 10 to 100 seconds. Inflow and outflow lines (32, 36) run within an insulation space (40) in the fashion of a thermosiphon.Type: GrantFiled: March 18, 1997Date of Patent: May 2, 2000Assignee: Langerer & Reich GmbHInventors: Roland Strahle, Bernhard Stephan, Bernd Streicher
