The heat exchanger components (15) comprise stacked and spaced perforated circular pieces (10a) clamped on a central tube (18), with a loop (19) of solder flux introduced between adjoining pieces. This loop is bent downwards along its periphery to preserve piece spacing. When the stack, composed of the tube and circular pieces (10a) with intermediary soldering flux, is ready, it is placed in a pipe (21) which is heated so that the flux melts, and forms metallic contact between the circular pieces and the pipe. |
