A hollow tank body portion (11) is formed by folding a plate of aluminium clad with a brazing filler metal layer (R). One end of the plate material (11a) extends over the other end (11b) and the thus overlapped ends (11a, 11b) are brazed together. Preferably these overlapped portions (11a, 11b) provide a locating portion for a mounting bracket (25 Fig 6) to hold it in place as it is brazed. <IMAGE> |
