Abstract
Disclosed is a heat exchanger for a combustion engine, comprising a first connection zone (1, 102) for delivering a fluid that is to be cooled, at least some of said fluid being composed of exhaust gas of the combustion engine, a second connection zone (3, 103) for discharging the fluid, and an exchanger zone (2, 101, 104, 105) which is arranged between the first and the second connection zone relative to a flow path of the fluid. A coolant can flow around the exchanger zone (2, 101, 104, 105) while at least part of the heat exchanger is made of ferritic steel.
Claims29
