Exhaust gas heat exchanger with vibration damped - tube bundle heat exchanger

摘要

Heat exchanger (1) for the exhaust line of a motor vehicle with a bundle formed separately, is connected in parallel to the exhaust-gas-carrying in terms of flow tubes (20), which in a separately formed closed housing (40) are arranged, which is a coolant flows through the exchanger tubes (20) on the outside around it, wherein the exchanger tubes (20) between the points (66, 68), on which they are conveyed by the wall of the housing (40) are guided substantially u - or are curved in a semicircle, wherein a mechanical means (30; 34; 70; 72) is provided, by means of the exchanger tubes (20) is supported on one another, characterized in that the mechanical means (30; 34; 70; 72) of the bundle heat exchanger tubes (20) mechanically connected with one another and forms a resilient support, so that a resilient support of the exchanger tubes (20) with respect to the housing (40) is used and that, the mechanical means (30; 34; 70; 72) in the region of the u - shaped deflection of the exchanger tubes (20) is arranged.
