リンボーンの形体とした。 The configuration will be described below with reference to the drawings shown as examples. Reference numerals 1 and 2 are plates, and the same plates are rotated 180 degrees and stacked one on top of the other to form a heat exchanger. Numerals 3, 3', 3a, 3a', 4, 4' and 4a, 4a' are pairs of fluid passage holes preset on the plate so that the fluid crosses the heat transfer surface. It is symmetrical about the center point of the board. 5 and 6 are gaskets surrounding the heat transfer surface and the pair of fluid passage holes. 7 and 8 are heat transfer surfaces, and the illustrated example has a herringbone shape.

３図においてもθ＜45゜のときＡの流路では
NTU（熱移動単位数）が低く、Ｂの流路では
NTU（熱移動単位数）が高くなる。 The plates 1 and 2 are exactly the same. The pair of fluid passage holes are symmetrical about the center point of the plate, so as shown in Figures 1 and 2.
The figure shows a plate 1 surrounded by a gasket 5 so that a flow path is formed by the fluid passage holes 3 and 3', and a gasket that is surrounded by a gasket 5 so that a flow path is formed by the fluid passage holes 4 and 4'. A plate plate 2 surrounded by 6 was provided. A large number of these two plates are stacked as a pair to exchange heat between the two fluids. The fluid channels A and B have different inclination angles as shown in FIG. Therefore, even in the same plate, the values of heat transfer coefficient and pressure loss change between the front and back surfaces. In the example shown, the heat transfer surfaces of the herringbone feature are 180 degrees from each other.
Since they overlap at the rotated position, the distance between the plates and the formation of the peaks and valleys are the same, but the positions of the fluid passage holes 3, 3' and 4, 4' are aligned with the plate center line Y-
Since they are separated by different distances la and lb with Y' as the center, the angle at which the fluid hits the herringbone peak is different, and the turbulence effect given to the fluid is different. In Fig. 3, when θ < 45°, A in the flow path
NTU (number of heat transfer units) is low, and in channel B
NTU (number of heat transfer units) becomes higher.

に応用して非常に便利であり、産業上の利用範囲
は広い。 In this way, by selectively opening any fluid passage hole from multiple sets of fluid passage holes, it is possible to change the heat transfer coefficient and pressure loss using the same plate. It is very useful for heat exchange between fluids, heat exchange between gas and liquid, and even when heat exchange between liquids such as oil and water has different physical properties, and the range of industrial use is wide.
尚、伝熱面はヘリンボーンに限定することな

ぶこともできる。 Incidentally, the heat transfer surface is not limited to a herringbone type, and any type such as a corrugated type or an uneven type can be used. Further, the example shown in FIG. 4 shows an example in which a pair of passage holes which are not symmetrical with respect to the center point of the plate are selected and opened to form a flow path according to the purpose. For example, the inclination state of the flow path can be arbitrarily selected by combining not only 10d but also 10c with respect to 9a.
