Patent ID: 8132547

Claim:
A thermal energy management system developed by an automotive vehicle thermal engine, comprising: a high-temperature circuit including the vehicle engine and a high-temperature cooling radiator; a low-temperature circuit including a low-temperature cooling radiator, wherein the high-temperature circuit and the low-temperature circuit are run through by a same heat carrier fluid; an assignable cooling radiator; first switching means inserted between the high-temperature circuit and the assignable cooling radiator; and second switching means inserted between the low-temperature circuit and the assignable cooling radiator in order to switch the system from a connected configuration in which the assignable cooling radiator is connected to the low-temperature circuit, to a disconnected configuration, in which the assignable cooling radiator is connected to the high-temperature circuit, and conversely from the disconnected configuration to the connected configuration, wherein the first and second switching means are sequentially operated after a time delay during the passage from the disconnected configuration to the connected configuration and from the connected configuration to the disconnected configuration, in order to minimize thermal shocks.
