HEAT EXCHANGE MODULE, PARTICULARLY FOR A MOTOR VEHICLE, COMPRISING A MAIN RADIATOR AND A SECONDARY RADIATOR, AND SYSTEM COMPRISING THIS MODULE

摘要

The invention concerns a heat exchanger module comprising a main exchanger (4) and a secondary heat exchanger (6) including each an input header (8, 34), an output header (10, 36), a bundle of tubes (12, 38) and exchange surfaces associated with the tubes of the bundle. The two exchangers are run through by a common air stream (42). Preferably, the output header (10) of the main exchanger (4) communicates with the input header (34) of the secondary exchanger (6) through a passageway orifice (32). A separating partition (20) divides the output header of the main exchanger (4) into a main output chamber (22) and a secondary output chamber (24).
