Abstract

Un dispositivo (10) scambiatore di calore comprende fasci (12, 12') di tubi paralleli percorsi da un primo fluido e contenuti in un involucro (11) entro cui scorre un secondo fluido. I tubi dei fasci (12, 12') sboccano in camere di testa (15, 17, 23) dell'involucro, le quali costituiscono connessioni in serie fra i fasci e raccordi di ingresso e uscita del primo fluido dallo scambiatore (10). I tubi dei fasci sono disposti nell'involucro (11) in stretta adiacenza reciproca e con le pareti dell'involucro ed hanno porzioni di estremità a sezione ridotta per creare nell'involucro camere collettrici (18, 19, 27, 28) del secondo fluido, le quali costituiscono interconnessione degli spazi fra i tubi e connessioni per ingressi (25) e uscite (29) di circolazione di detto secondo fluido.
