Abstract
The invention relates to an exhaust heat exchanger (), in particular an exhaust cooler for motor vehicles with exhaust recycling, comprising a housing sleeve () for a coolant and a nest of tubes () with exhaust flowing through and coolant circulating around the above which are mounted on the housing sleeve by means of tube plates (), whereby said nest of tubes, the tube plate and the housing sleeve form a closed force flow. According to the invention, a sliding seating () is arranged in the force flow, either in the housing sleeve or between a tube plate and the housing sleeve. The various expansions of the nest of tubes and of the housing sleeve are thus compensated for, such that unsupportable high loads do not occur in the components of the exhaust heat exchanger.
