Abstract
The inventive management system comprises a high-temperature circuit (12) provided with a high-temperature cooling radiator (20), a low-temperature circuit (14) provided with a low-temperature cooling radiator (30, 30a, 30b), wherein the same heat carrier fluid runs through said circuits. Said system also comprises a radiator (36) assignable to first switching means (52) and to second switching means (54) for switching the system from a connected configuration, in which the assignable radiator (36) is connected to the low-temperature circuit (14), to a disconnected configuration, in which the assignable radiator is connected to the high-temperature circuit (12), and vice-versa. The switching means are sequentially actuated after a time-delay during switching from the disconnected configuration to the connected configuration and/or from the connected configuration to the disconnected configuration in order to minimize thermal shocks in the assignable cooling radiator (36).
