CIRCUIT FOR THE THERMAL MANAGEMENT OF A HYBRID OR ELECTRIC VEHICLE

A thermal management circuit for a hybrid or electric vehicle is disclosed. The thermal management circuit has a first reversible air conditioning loop in which a refrigerant circulates and includes a two-fluid heat exchanger arranged jointly on a second loop for the circulation of a heat-transfer fluid. The second loop for the circulation of a heat-transfer fluid includes a first circulation branch including in the direction in which the heat-transfer fluid circulates, a first pump, a first radiator arranged in an internal air flow, and a battery heat exchanger. A second circulation branch is connected in parallel with the second radiator and includes a second pump and an electric device for heating the heat-transfer fluid. A third circulation branch connected in parallel with the first pump and the battery heat exchanger includes the two-fluid heat exchanger.
