In this conventional condenser a, flat tubes b in the shape of bows and cooling fins c installed between the flat tubes b are separately prepared, and these are integrated by heating and brazing. Conventionally, in order to connect condensate conduits (not shown) to both ends of the flat tube b, unions d and e on the inlet and outlet sides are welded (usually argon welded) as shown in Fig. 2. It is connected and fixed at f.
しかし、上記アルゴン溶液は、作業性が悪く、
作業コストが高くなるという不具合がある。 However, the above argon solution has poor workability and
There is a problem that the work cost increases.

照）。 Therefore, a flange plate consisting of a core material sandwiched between brazing materials is provided on the flat tube, and after this flat tube is connected to the union via the flange plate,
A technique for expanding a flat tube and infiltrating the brazing material into the gap between the two by heating, and
A notch is provided in the partition wall of the flat tube to a depth of a predetermined distance from the tube end,
A technique has been proposed in which the end of the flat tube is inserted into a flange plate, expanded, and heated to braze the gap between the two (see Japanese Utility Model Application Publication No. 112063/1983).
しかし、これらの技術では、作業性の悪いアル
ゴン溶液を廃止することができる点において優れ

また、前者では、鍔板と扁平チユーブとの間に
は、隙間が生じて、ロー材の回りが悪いという欠
点がある。 In addition, the former has the disadvantage that a gap is created between the flange plate and the flat tube, making it difficult for the brazing material to move around.
さらに、後者では、扁平チユーブに切込みを設

具合がある。 Furthermore, in the latter case, since it is necessary to make a cut in the flat tube, there is a problem that the structure becomes complicated.
さらにまた、これらの技術では、鍔板とユニオ
ンの端部との嵌合部をロー付けするため、加熱時
にロー材が漏れやすく、接合強度に難がある。 Furthermore, in these techniques, since the fitting portion between the flange plate and the end of the union is brazed, the brazing material tends to leak during heating, resulting in poor bonding strength.
