Zusammenfassung:The device has a set of flow channels connected with an exhaust gas duct of an internal combustion engine e.g. motor vehicle diesel engine, where a cooling medium flows through the channels for dissipating the heat of the exhaust gas. Inserts (7) arranged in an inner side of the channels stay in thermal contact with the channels, where the gas flows through the inserts. The inserts comprise bar ribs (8), where successive bars (9) of the ribs are arranged to be displaceable from one another in a flow direction of the exhaust gas.
