It is also apparent from FIGS. 13 and 14 that it is advantageous to form at the ends of the strip 110 a hook 13 which is adapted to hold the side member 30 firmly against the outer rib 4. This also supports the cohesion of the entire heat exchanger before soldering. Furthermore, this also suppresses the above-mentioned "sticking out" of the strip 110 from the wall 107.
