20090218085 | 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. | 09-03-2009 |
20100192569 | EXHAUST GAS SYSTEM AND METHOD FOR RECOVERING ENERGY - A system and method for recovering energy from gases of an internal combustion engine in conjunction with exhaust gas recirculation is described and illustrated, and in some embodiments includes an exhaust gas recirculation valve and an exhaust gas recirculation heat exchanger, with a working medium which undergoes a cyclic process being evaporated in the exhaust gas recirculation heat exchanger by hot exhaust gases, and with resulting steam being converted into mechanical or electrical energy which is available as additional energy. To improve heat recovery with little technical expenditure, an exhaust gas control valve can interact with the exhaust gas recirculation heat exchanger, and can control the mass flow of exhaust gases flowing through the exhaust gas recirculation heat exchanger constantly in all operating phases of the internal combustion engine, approximately in the vicinity of the performance limit of energy recovery. | 08-05-2010 |
20120255288 | HEAT EXCHANGER PLATE AND AN EVAPORATOR WITH SUCH A PLATE - A heat exchanger plate for an evaporator includes a flow transverse distribution device. Disks of the flow transverse distribution device conduct the medium to be evaporated to the flow channel extending in the direction of the longitudinal axis. The disks include openings allowing a flow of the medium in the direction of the longitudinal axis with comparatively higher flow resistance than in the direction of the transverse axis. The number of disks arranged one behind the other in the direction of the longitudinal axis varies over the width of the heat exchanger plate in the direction of the transverse axis. On each width section, in which the entry of the medium into the disks arranged one behind the other is intended, the comparatively largest number of disks is provided one behind the other. As the distance from the entrance increases, the number decreases in the direction of the transverse axis. | 10-11-2012 |
