| 20090014164 | FLAT TUBE, FLAT TUBE HEAT EXCHANGER, AND METHOD OF MANUFACTURING SAME - 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. | 01-15-2009 |

| 20100024508 | TUBES AND METHOD AND APPARATUS FOR PRODUCING TUBES - 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. | 02-04-2010 |
| 20100108304 | HEAT EXCHANGER AND METHOD OF ASSEMBLING SAME - The invention provides for a manufacturing process of a heat exchanger having a flat tube and fin core. The flat tube and fin core is formed in such a way that free flat tube ends are provided, wherein the flat tube and fin core is brazed in a brazing furnace, and wherein the flat tube ends are received in receptacle openings of a mounting plate and a header forming an enclosed space for receiving a bonding agent for coupling the flat tube ends to the header and mounting plate. | 05-06-2010 |
| 20100170668 | HEAT EXCHANGER HAVING A PLASTIC COLLECTING TANK - 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. | 07-08-2010 |
