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. |
