Abstract

L'INVENTION CONCERNE LES ECHANGEURS THERMIQUES, EN PARTICULIER POUR DES TURBINES A GAZ DE GRANDE PUISSANCE FONCTIONNANT A UNE TEMPERATURE ELEVEE, DE L'ORDRE DE 650C PAR EXEMPLE. L'ECHANGEUR COMPORTE UN COEUR 30 CONSTITUE D'UN EMPILEMENT DE PLAQUES MINCES, PRESENTANT DES OUVERTURES ALIGNEES POUR AU MOINS UN COLLECTEUR 34 D'AIR SOUS PRESSION, ASSOCIE A UN CIRCUIT EXTERNE. LE COEUR 30 EST SUJET A DES DILATATIONS THERMIQUES EN COURS DE FONCTIONNEMENT. AU MOINS UN RACCORD DEFORMABLE 32, MONTE ENTRE LE COLLECTEUR 34 ET LE CIRCUIT EXTERNE, COMPORTE UN SOUFFLET DE LIAISON 56 MIS SOUS PRESSION PAR L'EXTERIEUR. LE SOUFFLET 56 PRESENTE UNE SURFACE ANNULAIRE CHOISIE POUR PROVOQUER, SOUS L'EFFET DE LA PRESSION DE FONCTIONNEMENT DU SYSTEME, UN EFFORT SUFFISANT POUR MAINTENIR UN EFFET DE COMPRESSION SUR LE COEUR 30 DE L'ECHANGEUR, DANS TOUTES LES CONDITIONS DE FONCTIONNEMENT PREVUES. APPLICATION AUX ECHANGEURS THERMIQUES COMPORTANT UN COEUR A PLAQUES MINCES, POUR EN AMELIORER L'ENDURANCE AUX DILATATIONS REPETEES.
