Beschreibung
Zusammenfassung:	A heat exchanger (10) with a pressurised shell (11) and a tube bundle (18) with exchanging tubes (18a) between flexible tubesheets (16, 17) has the flexible tubesheets (16, 17) reciprocally interconnected by tie rods (21) in a central zone of the tubesheets (16, 17) which is devoid of exchanging tubes (18a) and the exchanging tubes (18a) in the tube bundle (18) are arranged around such tie rods (21 ). The exchanger may further comprise conveying diaphragms (23, 24) arranged along the bundle shaped, alternately, as discs and rings. L'invention concerne un échangeur de chaleur (10) muni d'une calandre (11) sous pression et d'un faisceau tubulaire (18) comportant des tubes échangeurs (18a) entre des plaques tubulaires flexibles (16, 17). Les plaques tubulaires flexibles (16, 17) sont raccordées réciproquement par des barres de liaison (21) dans une zone centrale des plaques tubulaires (16, 17) dépourvue de tubes échangeurs (18a), et les tubes échangeurs (18a) dans le faisceau tubulaire (18) sont disposés autour des barres de liaison (21). L'échangeur peut comprendre en outre des membranes de transport (23, 24) disposées le long du faisceau en forme de disques et de bagues en alternance.
