ューブ間に位置して、切欠穴を設けることを本出願人は
実願昭５４−９５４２２号にて提案している。In other words, this kind of heat exchanger with corrugated fins has the disadvantage that condensed water (drain water) accumulates in the corrugated part, obstructing air flow and reducing heat exchange efficiency. The applicant proposed in Utility Model Application No. 54-95422 to provide a cutout hole located between the mating tubes.

を下方に滴下するよう構成している。Further, a long hole 3 extending in the bending direction is formed between the adjacent tubes 1 and 1' of the corrugated portion located below of the corrugated portion 2', and drain water is dripped downward from this long hole 3. It is configured like this.
この長孔３を形成するに際しては第４図の展開図で示す
如く平板状のフィン２にルーバ２″。When forming the elongated hole 3, a louver 2'' is attached to the flat fin 2, as shown in the developed view of FIG.
２″・・・・・・と長孔３とを同時に形成し、特に長孔

ある。2''... and the elongated hole 3 at the same time, especially for the elongated hole 3, the bending line (after bending, the corrugated part 2',
2'...) at every - interval, and then the second . It is bent as shown in FIG.

も出現するといった問題があった。Therefore, due to elongation of the material of the fin-forming band material and play in the meshing of the roller dies, the position of the bent portion may shift, and even if the elongated hole 3 is provided in advance, the elongated hole 3 2, 2'...
There have been problems in that some products have become useless for draining drain water.
そこで本考案は上記欠点を解消すべく、コルゲート部に
は必ずドレン水排出のための孔が形成されるように威し
たもので、以下その一実施例を第５図〜第６図により説
明する。Therefore, in order to eliminate the above-mentioned drawbacks, the present invention is designed to ensure that the corrugated portion is always provided with a hole for discharging drain water.One embodiment of the invention will be explained below with reference to Figs. 5 and 6. .
この図において符号１〜２は第１〜４図と同一物を示し
説明は省略する。In this figure, numerals 1 to 2 indicate the same parts as in Figs. 1 to 4, and their explanation will be omitted.
４，４・・・・・・及び５，５・・・・・・は隣合うチ

るよう、いわゆる千鳥状に配列されている。4, 4... and 5, 5... are arranged at equal intervals in the longitudinal direction of the fins 2 between the adjacent tubes 1, 1', that is, in the direction perpendicular to the corrugated portion 2'. It is a long hole that is provided so that the long holes 5, 5, etc. of the other row are located so as to overlap the intervals between the rows of long holes 4, 4, etc. on one side. They are arranged in a staggered pattern.
したがって、このフィン２を折曲すること、コルゲート
部分２′にはいずれかの列の長孔４又は５が必ず位置す
ることになる。Therefore, when the fins 2 are bent, the elongated holes 4 or 5 in one of the rows will necessarily be located in the corrugated portion 2'.
したがってドレン水はコルゲート部分に位置する長孔が
排水穴となって排水が行なわれるものである。Therefore, the drain water is drained through the long holes located in the corrugated portion.
以上の説明からも明らかな如く、本考案の熱交換器は、
フィンの隣合うチューブ間に、少なくとも２列の長孔を
千鳥状に配列しているので、フィンの折曲げによるコル
ゲート部にはいずれかの長孔が必ず位置することになる
ので、従来の如く、排水穴としての長孔がコルゲート部
に位置しないことによる排水不良をもたらさず、又組立
時にフィンの上下関係を考慮せずとも良いため組立工程
のスピード化が計れるものである。As is clear from the above explanation, the heat exchanger of the present invention is
Since at least two rows of long holes are arranged in a staggered manner between adjacent tubes of the fin, one of the long holes will always be located in the corrugated part when the fin is bent. This eliminates the problem of poor drainage due to the fact that the elongated drainage hole is not located in the corrugated portion, and the assembly process can be speeded up since there is no need to consider the vertical relationship of the fins during assembly.
