Concentric counter=current heat exchanger with aeration

摘要

The ends of the concentric metal tubes (2,4,6) in the casing jacket are interconnected by rings (9,10,12,13). The terminal points of the concentric tubes are releasably coupled by bolts (15) to a tube (7) and to the top and bottom tube plates (8,14). To the terminal points are coupled flow directing tubes (1,3,5) shorter than the concentric ones. Pref. the cold fluid chambers (A,B) in the top section are coupled to headers (21,22) by small tubes (20), while the hot fluid chambers (C,D) are coupled to the lower section of the header (23,24).
