Abstract

DISPOSITIF DE REFROIDISSEMENT D'UN ROTOR DE MACHINE ELECTRIQUE COMPORTANT UN ENROULEMENT DE CHAMP SUPRACONDUCTEUR ET, TOURNANT AVEC LUI, AUSSI BIEN UN ECRAN THERMIQUE QU'UNE CHAMBRE DE MELANGE RENFERMANT LE REFRIGERANT EN DEUX PHASES. L'ENROULEMENT DE CHAMP 3 EST REFROIDI PAR UNE MULTIPLICITE DE BOUCLES EN THERMOSIPHONS S1 BRANCHEES PARALLELEMENT LES UNES AUX AUTRES, LESQUELLES SONT REPARTIES SUR LA LONGUEUR AXIALE DU ROTOR R ET RELIEES A DES SECTEURS DE CHAMBRE DE MELANGE M1, M2... M REPARTIS DE FACON CORRESPONDANTE. L'INVENTION S'APPLIQUE PARTICULIEREMENT A DES TURBO-ALTERNATEURS A ENROULEMENT DE CHAMP SUPRACONDUCTEUR.
