Abstract (en)
[origin: WO2008116992A1] A main circuit (9) cools a first set of elements of the motor propulsion unit to a first temperature level. A secondary circuit (26) cools a second set of elements to a second temperature level, lower than the first level. A main radiator (10) is sub-divided into at least one main chamber (18) making up part of the main circuit and a secondary chamber (19) making up part of the secondary circuit. A thermostatic valve (8) is arranged in the main circuit (9) downstream of the heat engine, which isolates the main radiator (10) when the temperature is below a first threshold. An expansion chamber (12) is arranged downstream of the thermostatic valve (8). The secondary compartment (19) can also be part of the principal circuit (9) in one operating mode of the system. An auxiliary radiator (11) is arranged parallel to the principal radiator (10). A controlled valve (34) is arranged in a branch (35) such as to totally shut when the temperature of the heat transfer fluid is below a second threshold above the first threshold.
