その板の間の空間に伝熱管を差し込んで伝熱管を支持す
るもので、これはエラグクレートと呼ばれている。(Prior art) A typical method for effectively suppressing vibrations and preventing deflection of heat transfer tubes is to provide a large number of holes with a diameter slightly larger than the outside diameter of the heat transfer tube in a thick plate. This is a baffle plate that is bored and supports the heat transfer tubes inserted into the holes. However, in order to drill holes in this baffle plate, it is difficult to drill holes in several baffle plates at the same time. Center misalignment t when inserted into the hole:
It becomes difficult to pass the heat transfer tube through the tube hole, making assembly extremely difficult. In order to eliminate this bottleneck, a method was devised to support the heat transfer tubes by combining thin and narrow plates in a lattice pattern and inserting the heat transfer tubes into the spaces between the plates.This is called an Elagu crate. It is.

The figure and FIG. 7 show how the Elag crate is supported by the constituent materials. In Figure 6, thin plates 1.2 are assembled in a grid pattern.
forms a diamond-shaped space, the heat exchanger tubes 3 are inserted into this diamond-shaped space, the movement of the heat exchanger tubes 3 in the radial direction is restrained, and they are arranged in multiple rows in the tube axis direction,
This is useful for suppressing vibrations and preventing deflection of the heat exchanger tubes 3.

ものであるが、次のような難点もある。(Problems to be Solved by the Invention) Although the support method using the Elag crate constituent material described above is effective in suppressing vibrations and preventing deflection of the heat exchanger tubes, it also has the following drawbacks. .

集中して発生し、局部的な肉厚の減少から伝熱管３に破
損か生し易くなる。In other words, in the support method using these two types of thin plates 1.2, the number of contact points between the heat exchanger tube 3 and the thin plates 1.2 is at most four points, and when vibration is caused by the fluid outside the tube, Wear caused by the above-mentioned friction of both members is concentrated at this point, and the heat exchanger tube 3 is likely to be damaged due to the local decrease in wall thickness.

れかある。In addition, with this method of support using the thin plate 1.2, it is necessary to weld the parts where the two parts fit together to ensure the strength of the tube support lattice. There is a risk that it will become difficult to maintain the heat exchanger tubes 3 through the diamond-shaped space, and the assembly will be hindered.
一方、台形状に折り曲げた薄板４による管支持格子体に
おいては上記２つの問題か全く同し形で現われることは
ないにしても、状況は僚でいる。On the other hand, in a tube support grid made of thin plates 4 bent into a trapezoidal shape, the two problems described above are similar, although they do not appear in exactly the same way.
特に薄板４同士はスポット溶接で固定されねばならない
か、このとき薄板４に歪みが生し、組立精度を維するの
が難しくなる。In particular, the thin plates 4 must be fixed to each other by spot welding, or in this case, distortion occurs in the thin plates 4, making it difficult to maintain assembly precision.

This is a tube support lattice body composed of a heat exchanger tube, and is characterized in that the unit space is formed in a hexagonal shape so that six contact points are provided between the outer peripheral portion of the heat exchanger tube and the thin plate.

When the heat exchanger tube vibrates, both members rub at the contact points, causing wear on the heat exchanger tube, but as the number of contact points increases from 4 to 6, wear is suppressed and the locally generated wall thickness is reduced. The heat exchanger tubes can be protected from the decrease in Therefore, even when the heat exchanger is operated for a long period of time, the heat exchanger tubes are not damaged and the integrity of the equipment can be maintained.

This figure shows the detailed shapes of the two, and except for the notches, they all have almost the same thickness, and there is no big difference in width. The first thin plate 11 shown in FIG. 4(a) has a notch 11a on one end surface thereof, the width of which is slightly wider than the thickness of the thin plate material, and the pitch of which is equal to the pitch of the heat exchanger tubes.

The notches 12b and 12a are combined with the notches 13b, respectively, and the thin plates are fixed to each other. Note that the depth of the cut is determined by whether the thin plates overlap each other, or especially the first thin plate 11.
The dimensions are determined so that the end faces of the third thin plate 13 and the third thin plate 13 do not interfere with each other.

である。The present embodiment has the above-described configuration, and the heat exchanger tube 14 is supported at two locations on each of the first, second, and third thin plates 11, 12, and 13. In other words, the heat exchanger tube 14 has a maximum number of contact points, and even when the heat exchanger tube 14 vibrates due to external fluid or excitation force, the friction between both members increases by the increase in the number of contact points. It is possible to suppress wear due to

The spacing between the slits 22a and the notches 22b is equal to the pitch of the heat exchanger tubes.
