Classification: CPC H  B  Y | IPC B  H

Claim 8:
9. A heat treatment system for a vehicle, for a heat treatment of at least a first element of an electric drivetrain and of a second element of the electric drivetrain, the heat treatment system comprising:
at least a loop for heat-transfer liquid comprising:
at least a first network, and
a second network,
wherein the first network comprises a first pump configured to induce circulation of the heat-transfer liquid, and a first heat exchanger configured to be thermally coupled to the first element of the electric drivetrain of the vehicle;
wherein the second network comprises a second pump configured to induce movement of the heat-transfer liquid, a second heat exchanger configured to be thermally coupled to the second element of the electric drivetrain of the vehicle, and a radiator arranged to be traversed by an outside air flow external to a cabin of the vehicle;
wherein the radiator comprises at least one input, a first cooling zone for the heat-transfer liquid supplying a first output of the radiator, and a second cooling zone for the heat-transfer liquid supplying a second output of the radiator, the first output being connected to the first heat exchanger, and the second output being connected to the second heat exchanger, and
wherein the first network and the second network are connected by a connection duct which extends from a valve, arranged in the first network, to a connection point contained in the second network between the at least one input of the radiator and the second heat exchanger,

a refrigerant circuit dedicated to the heat treatment of the first element of the electric drivetrain.
