ABSTRACT:
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.
