HEAT EXCHANGER OF AN INTERNAL COMBUSTION ENGINE

摘要

A heat exchanger (18) is provided for an internal combustion engine (1) for heat transfer between a gas stream (8) and a working medium stream (10). The heat exchanger (18) comprises a housing (28), which encloses a gas path (38), and with at least one spiral tube (29), which carries a working medium path (30) and which is arranged in the gas path (38) and which extends helically in relation to the central longitudinal axis (31) of the housing (28). Increased fatigue strength is achieved with an elastic outer mounting layer (32). The elastic outer mounting layer (32) is arranged between the housing (28) and the at least one spiral tube (29).
