Patent number: 8033323Abstract: The invention relates to a heat exchanger having a bundle of tubes, which can be inserted into a tubular housing. Exhaust gas can flow through the tubes. A coolant duct can be arranged between the tubes. The bundle of tubes can have at least one grid-like securing structure which supports the bundle in the housing. The behavior of the heat exchanger with respect to vibrations is improved by virtue of the fact that the grid-like metallic securing structure includes integral hook-shaped protrusions which are deformed in the opposite direction to the insertion direction of the bundle into the housing. The spring force is directed against the housing in order to dampen vibrations. The heat exchanger can also include an elastic device for permitting a change in length caused by temperature changes.Type: GrantFiled: June 18, 2007Date of Patent: October 11, 2011Assignee: Modine Manufacturing CompanyInventors: Harald Schatz, Stefan Muller-Lufft, Heitel Ingo, Omur Acar, Jorg Soldner, Michael Daniel, Bjorn Volquardsen

Patent number: 8020610Abstract: The invention relates to an exhaust gas heat exchanger in an exhaust gas recirculation arrangement. The heat exchanger includes a plate stack which is surrounded by a housing. The plate stack can include two plates which are connected at their longitudinal edges to form a flat tube which contains a turbulator through which exhaust gas flows. The heat exchanger can also include a coolant duct which is equipped with flow directing elements arranged between two flat tubes. In order to make the exhaust gas heat exchanger more resistant to changing temperature stresses, the invention provides that the flow directing elements can be formed from a corrugated plate in which ducts with inlets and outlets are formed. At least some of the ducts in the inlet area of the coolant have a nonlinear profile so that changes in length are permitted between the plate stack and the housing.Type: GrantFiled: February 6, 2007Date of Patent: September 20, 2011Assignee: Modine Manufacturing CompanyInventors: Jörg Soldner, Sven Thumm, Roland Strähle, Harald Schatz
