The heat exchange group 6 is formed by arranging them in a meandering manner.
そして、この熱交換群６を、ベンド部５を連続させたま
ま複数体（第２図実施例の場合三体）成形するのである

できるのである。That is, in the illustrated embodiment, the two ends of the two refrigerant pipes 1, e and f, which are the original ends of the refrigerant pipes 1, are welded and connected, respectively, and the points a and b, which were cut during bending, are connected by welding, for example, at U. The locations C and d, which were welded and connected using the molded bend pipe 3 and were cut in the same manner, are left open for the inflow and outflow of the refrigerant. That is, even though the refrigerant pipe 1 is made long, there are only three welding points including both ends, and by this connection, the refrigerant pipe 1 can be made into one flow path.

実施することができる。Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, and can be implemented in any manner as long as the configuration described in the claims is not changed.
例えば、空気の流入側に於いてフィンのピッチを粗に、
空気の流出側に於いてフィンのピッチを密にすれば、熱
交換効率の向上を図れると共に、フィンに付着する結露
水が凍結して次第に大きくなり、フィン間にブリッジを
形成して目詰りが生じるのを防止することができる。For example, make the pitch of the fins coarser on the air inflow side,
By making the pitch of the fins closer on the air outflow side, it is possible to improve heat exchange efficiency, and the condensed water that adheres to the fins freezes and gradually grows, forming bridges between the fins and preventing clogging. This can be prevented from occurring.
