Heat exchanger i.e. cooler, for cooling re-circulated exhaust gas, in cooling circuit of heat engine of motor vehicle, has fluid inlets for inletting fractions of coolant, and fluid outlet for evacuating fractions of coolant at same time

摘要

The exchanger (10) has a case provided with a fluid inlet (14) to inlet a coolant to be cooled, and a fluid outlet (16) to outlet the coolant. A fluid circulation unit circulates the fluid between the fluid inlet and the fluid outlet. Another fluid inlet (18) inlets fraction (F1) of the coolant at temperature, and a third fluid inlet (20) inlets another fraction (F2) of the coolant at another temperature that is higher than the former temperature. Another fluid outlet (22) evacuates the fractions of the coolant at the same time. An independent claim is also included for a cooling circuit comprising a main line.
