Heat exchange housing, the heat exchanger assembly or with one or more heat exchangers, exhaust gas recirculation system, and charge air supply system using the heat exchanger

The invention relates to a heat exchanger housing (1) for at least one heat exchanger for heat exchange between a first fluid, in particular an exhaust gas or charge air, and a second fluid, in particular a coolant (6). According to the concept of the invention, a bypass passage (40) is integrated in the heat exchanger housing (1), wherein the housing includes a housing body (10) having a designed for the passage of the second fluid and for receiving a number of the first fluid flowed through the flow channels chamber ; one designed for flow of the first fluid bypass passage (40); wherein the chamber and the bypass channel (40) are formed integrally with the housing body (10).
