ついで第１図ロに示すように横方向にプレスに
よつて横の波形に形成する、これをＡ型と名づけ
たのである。 Then, as shown in FIG. 1B, it was laterally pressed into a horizontal wave shape, which was named Type A.
波形の形状は横方向の長さをＬ、波の山の高さ
をＷ、波形の横方向のピツチ（pitch）をｐとす

The outer side is fixed to the outer shell 11 (FIG. 5), wound up in a spiral shape, and the end is fixed to the inner shell 6 constituting the fluid header. The element section of the present invention is constituted by a plurality of sets of unit elements of type A and type B. Therefore, in type A, the height W and pitch P of the waveform peaks become smaller as the material is rolled up toward the inner shell 6.
しかしＢ型においては波形の山の高さとピツチ

レメント間の間隙は横方向、縦方向ともに1.0mm
〜1.5mm程度にすることが可能である。 Now, if the diameter of the wave is D (mm), then the design pressure P (Kg/cm 2 ) and the tensile strength of the material used (Kg/cm 2 )
cm 2 ) is constant, the thickness t (mm) of the metal plate has the relationship t = kD (1) (k, proportionality constant). Therefore, the smaller D is, the smaller the diameter of the waveform. t (metal plate thickness) can be made smaller. For example, t is 0.1~1mm
It is possible to set the degree of And the gap between a set of unit elements is 1.0mm in both the horizontal and vertical directions.
It is possible to make it approximately 1.5 mm.

る。 Gas enters the fluid header of the inner body through 9, enters each element portion through the gas inlet 4, becomes a liquid, enters the liquid header 6 through the lower outlet 5, and is discharged through the outlet 10. Water rises from the pipe 8, descends between the elements from the cleaning and cooling water spray nozzle 15 in the upper part, and accumulates in the drain receiver 17. Also, cooling water pipe 1 on one side
Water is sprinkled from 6, and air a 1 from the bottom is cooled.
