板３５をろう材３８．３９を介して配設する。First, the upper and lower plates 22 and 23 are used to form the tube 24, and the corrugated plate fins 25 are arranged inside.
The heat exchange element 21 is manufactured by disposing brazing foils 36 and 37 between both surfaces of the heat exchanger and the inner walls of the upper and lower plates 22 and 23, respectively, and crimping the peripheries of the upper and lower plates 22 and 23. In this case, the wax foil 36, 37 is disposed over the entire inner wall of each plate, leaving the openings 26, 27 of the upper and lower plates 22, 23. Next, a large number of heat exchange elements 21 are stacked. That is, the annular groove 31 of the upper plate 22 of one heat exchange element 21 is inserted into the opening 27 of the lower plate 23 of the other heat exchange element 21, and the side heat exchange elements 21.21 are connected. (See Figure 3). In this way, they are sequentially connected. At the same time, a mounting flange 34 and a closing plate 35 are installed on the uppermost and lower heat exchange elements 21.21 via brazing filler metals 38.39.
