This relates to a cooling circuit comprising a liquid circulation path and, arranged on the path: -in series, an engine (2) and a radiator (8), -mounted on a first leg in parallel between the inlet and the outlet of the radiator, a store-exchanger (10) containing at least one volume: --enclosing elements for storing and releasing thermal energy, involving a phase change material PCM, placed in a heat exchange relationship with said liquid (9), --and around which are arranged at least one first layer containing a PCM and one second layer containing a porous thermally insulating material, -and valves (14,16,18) so positioned as to direct the circulation of the liquid arriving from the engine toward the radiator and/or the store-exchanger. |
