MODULE FOR COOLING THE CHARGE AIR AND RECIRCULATED GASES FROM THE INTERNAL COMBUSTION ENGINE OF A MOTOR VEHICLE

摘要

The cooling module consists of a charge air cooler and of a recirculated exhaust gas cooler. The charge air cooler comprises a heat exchange bundle ( 2 ), an inlet header box for the air that is to be cooled and an outlet header box for the cooled air. The recirculated exhaust gas cooler comprises a heat exchange bundle ( 4 ) for cooling the recirculated exhaust gases, an inlet header box for the recirculated exhaust gases and an outlet header box for these gases. A wrapper consisting of two half-casings ( 7 and 8 ) accommodates the exchange bundles ( 2 and 4 ). The charge air cooler heat exchange bundle ( 2 ) and the recirculated exhaust gas cooler heat exchange bundle ( 4 ) are assembled in a single brazing operation. They are also assembled with one another during this same brazing operation, possibly at the same time as the two half-casings ( 7 and 8 ).
