A heat exchanger includes a casing, a fluid flow path extending between first and second ends of the casing; first and second bundles of heat exchanger tubes in first and second portions of a fluid flow path extending through the casing, and a third section of the fluid flow path connecting the first and second sections and having a sealing plate with one or more apertures for the fluid flow path to pass therethrough. By virtue of the sealing plate and its relationship with the adjacent structure of the heat exchanger, adjacent ends of the two bundles of tubes are each movable in at least one direction with respect to the casing and the other bundle of tubes.

Heat exchanger assembly and method

A heat exchanger includes 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 affected by outwardly curved metallic springs attached to the bundle of tubes which may be 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.
