| 20100059215 | PLATE TYPE OIL COOLER - An oil cooler for use in a motor vehicle radiator tank is made of a plurality of plate assemblies, each comprising a pair of plate shells. Each plate shell has opposite upstanding walls, and the plate shells are nested so that the upstanding walls are in contact and sealed along their peripheries. The plate shells have deformed walls forming serpentine passageways in thermally conductive communication with the plate shells to transfer heat from the oil, and deformed projections extending into the interior space in passageways cause turbulence in the oil. Fittings for passage of oil into and out of the oil cooler have a flange with a groove and an elastomeric gasket with an elliptical cross section to seal the fittings to the tank wall opening. The oil cooler is mounted within the tank so that it is located approximately equidistant from the front and rear tank walls. | 03-11-2010 |
| 20090158730 | METHOD FOR COOLING AN INTERNAL COMBUSTION ENGINE HAVING EXHAUST GAS RECIRCULATION AND CHARGE AIR COOLING - A system for cooling charge air from a turbo- or supercharger and exhaust gas recirculated from an exhaust gas recirculation valve in an internal combustion engine. The system includes a radiator and parallel charge air and exhaust gas heat exchanger units, the charge air heat exchanger unit having aluminum tubes and fins for air cooling the charge air, and the exhaust gas heat exchanger unit having stainless steel tubes and fins. The charge air heat exchanger and the exhaust gas heat exchanger units are each disposed adjacent the radiator, on the same or opposite sides. Alternatively, there is provided a pair of combined charge air cooler and exhaust gas cooler heat exchanger units, with a first heat exchanger unit having stainless steel tubes and fins, and a second heat exchanger unit having aluminum tubes and fins. The heat exchanger units are disposed on opposites sides of the radiator. | 06-25-2009 |
| 20090000776 | HEAT EXCHANGER FIN WITH RIBBED HEM - A serpentine fin for assembly between tubes in a heat exchanger core, and a method of making same from a metal strip. The strip edges have a hem comprising a double thickness of the strip material extending inward from the edge. The metal strip has folds extending across the strip width such that the strip forms a serpentine shape, with the folds being adapted to contact the tubes in the heat exchanger core. Multiple rows of split louvers are disposed between adjacent folds. Each row of split louvers comprises louvers having openings extending in the direction of the strip length and formed in a pair of adjacent, spaced louver banks. Ribs are disposed parallel to the louver openings adjacent the strip edges and in at least one center portion of the strip between the strip edges, and extend across the pair of louver banks. | 01-01-2009 |
| 20080308263 | HEAT EXCHANGER MANIFOLD SEALING SYSTEM - A heat exchanger manifold with improved sealing between the tank and header. The manifold includes a plastic heat exchanger tank having an opening for mating with a header and a lip extending substantially around a periphery of the opening. The lip has an outer surface and an upper surface extending outward of the tank opening, and a ridge extending upward from a portion of the upper surface extending substantially around the tank. The manifold further includes an aluminum heat exchanger header adapted to connect to a heat exchanger core. The header has a groove around the periphery thereof receiving the tank lip and a plurality of plastically deformable tabs extending from an edge of the groove. The tabs are bent inward and contact the ridge on the tank lip to secure the tank to the header. | 12-18-2008 |
