SCAMIATORE DI CALORE IN CONTROCORRENTE A DUE PIASTRE TUBIERE FISSE

摘要

A counterflow heat exchanger comprises two upper and lower parallely and coaxially facing tube plates wherebetween extends a tube nest incuding a plurality of tubes connected to the tube plates. Each tube has at one end an U bent over portion and the rectilinear portion of the tube nest, substantially constituting the heat exchange region, is included with an even distribution within an annular interspace defined between an inner jacket and an outer shroud affixed to the tube plates.
