Patent ID: 8499869

Claim:
A cooling system for a vehicle with hybrid propulsion, the cooling system comprising: a hydraulic circuit configured to flow a refrigerants, and comprising a main branch configured to cool a thermal engine, and a secondary branch configured to cool electrical components; and at least one common radiator comprising a first portion in communication with the main branch of the hydraulic circuit, the first portion comprising at least two first portion trays arranged at first portion ends, the at least one common radiator comprising a second portion in communication with the secondary branch of the hydraulic circuit, the second portion comprising at least two trays arranged at second portion ends; a first circulation pump in communication with the main branch and configured to be mechanically driven to flow the refrigerant through the main branch and to be operated directly by a motor shaft of the thermal engine; a second circulation pump in communication with the secondary branch and configured to be electrically driven to flow the refrigerant through the secondary branch; a first movable partition configured to alternatively place a first tray of the first portion in communication with a second tray of the second portion and to isolate the first tray of the first portion from communication with the second tray of the second portion; a second movable partition configured to alternatively place a third tray of the first portion in communication with a fourth tray of the second portion and to isolate the third tray of the first portion from communication with the fourth tray of the second portion; and a control unit configured to drive one or both of the first movable partition and the second movable partition to maintain the first tray of the first portion isolated from communication with the second tray of the second portion and to maintain the third tray of the first portion isolated from communication from the fourth tray of the second portion when the thermal engine is active and the second circulation pump is running.
