Abstract

The invention relates to a gas heat exchanger, in particular for the exhaust gases of an engine. It comprises a first part (2) arranged at the inlet for the gases, which is made of a first metal, and a second part (3) arranged following the said first part (2) along the gas stream, which is made of a second metal having a melting temperature lower than that of the said first part (2), wherein the said first part (2) is capable of reducing the temperature of the gases before they pass through the said second part (3). Preferably, the first part (2) is made of stainless steel and the second part (3) is made of aluminum. A heat exchanger is obtained which has the advantages of combining stainless steel and aluminum and of maintaining suitable efficiency and costs.
