A HEAT EXCHANGER APPARATUS (1) COMPRISES HEAT EXCHANGER TUBES (5) LOCATED TIGHTLY THROUGH OPENINGS (4) IN SPACED APART FIN PLATES (3) BETWEEN A PAIR OF END WALLS (2). MOST OF THE HEAT EXCHANGER TUBES (5) PASS THROUGH OPENINGS (4) IN THE END WALLS (2), BUT A SUFFICIENT NUMBER OF RIGID SUPPORT TUBES (10) EXTEND THROUGH THE FIN PLATES (3) AND ARE SECURED IN CLOSELY FITTING OPENINGS (7) IN THE END WALLS (2) TO RIGIDIFY THE APPARATUS.
