Description
【発明の詳細な説明】 この発明は対向流型全熱交換器に関する。[Detailed description of the invention] This invention relates to a counterflow type total heat exchanger.
最近は多数人の集まるホールとか、或いは住宅等におい
て、環境を一層快適にするために、熱交換器を備えた換
気装置が開発されている。Recently, ventilation systems equipped with heat exchangers have been developed in order to make the environment more comfortable in halls where a large number of people gather, or in houses.
その際熱交換材料として、湿気を吸収、発散、透過させ
るような材料（プラスチックフィルム、紙、布類等）を
使用すれば、顕熱のみならず、潜熱交換をも行なわせる
ことができる。In this case, if a material that absorbs, releases, or transmits moisture (plastic film, paper, cloth, etc.) is used as the heat exchange material, not only sensible heat but also latent heat exchange can be performed.
この種の熱交換器の欠点は対向流型の熱交換器を作るこ
とが難しいことで、熱交換材料を介して上下の交叉する
通路を二種の流体が流通するため全熱交換効率を高める
ためには大容量の熱交換器を作らねばならなかった。The disadvantage of this type of heat exchanger is that it is difficult to create a counterflow type heat exchanger, and the two fluids flow through the upper and lower intersecting passages through the heat exchange material, increasing the total heat exchange efficiency. In order to do this, we had to create a large-capacity heat exchanger.
この発明はこの欠点を除くために、熱交換部材としてパ
イプを用うる対向流型全熱交換器において、必要に応じ
て吸湿処理した。In order to eliminate this drawback, the present invention performs moisture absorption treatment as necessary in a counterflow type total heat exchanger that uses pipes as heat exchange members.
湿気を吸収、発散、透過させるような材料でできたパイ

口、出口が交互に、熱交換要素の左右半分づつに、上下
にならんでいるようにしたもので、双方の流体の入口出
口が熱交換器の前後で互いに隣接するため熱交換器に接
続される流路の接続を簡単に行なうことができ、しかも
簡単な構成で効率のよい対向流型全熱交換器を得たもの
である。Horizontal rows of pipes made of materials that absorb, wick, and permeate moisture are stacked vertically, with gaps between the top and bottom. The other fluid is made to flow in the opposite direction between them, and the upper and lower ends of the pipe are sealed with sheets sandwiched between them, and the inlets and outlets of both fluids are arranged vertically in the left and right halves of the heat exchange element alternately. Since the inlets and outlets of both fluids are adjacent to each other before and after the heat exchanger, the flow paths connected to the heat exchanger can be easily connected, and the simple configuration also improves efficiency. A good counterflow type total heat exchanger was obtained.
図について説明すれば、第１図は従来の構造の対向流型

を有し、その上下に流体の入口部Ａ、出口部Ｂを有し、
又シリンダーの側面の上下に他の流体の人口部Ｄ、出口
部Ｅを有している。To explain the diagrams, Fig. 1 shows a counterflow type heat exchanger with a conventional structure, and the heat exchanger HC is a cylinder C.
It has a fluid inlet part A and an outlet part B above and below it,
Also, there are an intake section D and an outlet section E for other fluids on the upper and lower sides of the cylinder.
そしてシリンダー内部には出口部Ｅの上方に管板Ｓ１、
及び入口部りの下方に他の管板Ｓ２が取りつけられ、管
板Ｓ１，８２間には多数のパイプＰが貫通している。Inside the cylinder, there is a tube plate S1 above the outlet E.
Another tube sheet S2 is attached below the inlet portion, and a large number of pipes P pass through between the tube sheets S1 and 82.
このような熱交換器では一方の流体Ｆ１ は入口部Ａか
ら流入し、パイプＰを通って出口部Ｂから流出する。In such a heat exchanger, one fluid F1 enters from the inlet A, passes through the pipe P, and exits from the outlet B.
他方の流体Ｆ２は下方の入口部りから流入し、パイプの
周りを流体Ｆ１ とは対向的に上方に流れ、出口部Ｅか
ら流出するものである。The other fluid F2 flows in from the lower inlet, flows upward around the pipe in opposition to the fluid F1, and flows out from the outlet E.
このような従来の構成では管板の取付も面倒であり管板
にパイプを取りつけるにしても、多数のパイプを精密に
取りつけねばならぬという手間がかかる。In such a conventional structure, it is troublesome to attach the tube sheet, and even if the pipes are to be attached to the tube sheet, it takes time and effort to precisely attach a large number of pipes.
この発明はこれらの欠点を除去し、簡単な構成で効率も
高い対向流型全熱交換器を得たものである。The present invention eliminates these drawbacks and provides a counterflow type total heat exchanger with a simple configuration and high efficiency.

When looking at the relationship between ・・・・・・・・・ from the direction of arrow R in Fig. 2, Fig. 5 corresponds to the ■-V line in Fig. 4? The sheet 22 has its edges bent upward and downward alternately from the center to the right half and the left half to form an upper folded part 22a and a lower folded part 22b.
（即ち一つのシート２２の右半分を上方折曲部２２ａ、
左半分を下方折曲部２２ｂとすれば、その一つ下方のシ

If the left half is defined as the lower folded part 22b, the right half of the sheet one sheet below it is defined as the lower folded part 22b, and the left half is defined as the upper folded part 22a.
以下同様である。The same applies below.

がなくなるようにする。The distance between the top and bottom of sheet 22 is the same as pipe 2.
The diameter of the pipe is slightly smaller than that of the pipe 1, and the flat part 21' is formed as shown in the left half of FIG. 4, so that there is no gap between the pipes between the sheets.
そしてパイプとシートとの間の隙間は後述する如く溶融
接着等でシールしてしまい、パイプとシートとでシール
部４を形成する。Then, the gap between the pipe and the sheet is sealed by melt adhesion or the like as described later, and the pipe and the sheet form a sealed portion 4.
パイプの他端部にも同様にシート２３・・・・−・・・

の全熱交換を行なうことができる。In the figure, the openings 24 communicate with the pipes 21, and the openings 25 communicate with the space between the pipe rows, so one of the openings 24 and 250 is used as an inlet and the other as an outlet. By this, when two types of fluids flow in countercurrents, countercurrent type total heat exchange can be performed.

a, the right half is the lower bent part 22b, and in the sheet 22 one below, the right half is the upper bent part 22a, and the left half is the lower bent part 22b.
そして右側の下方折曲部２２ｂと、一つ下のシートの上
方折曲部２２ａとを接着する。Then, the lower bent portion 22b on the right side and the upper bent portion 22a of the sheet one below are adhered.
左半分の上方折曲部２２ａと一つ下のシートの下方折曲
部２２ｂとの間に開口２４が形成される。An opening 24 is formed between the upper bent portion 22a of the left half and the lower bent portion 22b of the sheet immediately below.
今開口２４を入口とすれば、その左半分の開口から入っ
た流体は上下のシート２２内に入ってシール部−ばいに
ひろがり、パイプ２１に入って流れる。If the opening 24 is now used as an inlet, the fluid entering from the left half opening enters the upper and lower sheets 22, spreads to the seal portion, enters the pipe 21, and flows.
（前述の如くパイプとシートの間はシールされているの
で、流体は完全に分離される。(As mentioned above, the pipe and seat are sealed, so the fluid is completely separated.

A similar seal portion 5 is formed using...
尚シール部４，５との開口の位置は図示の如く反対とな

熱交換される流体の一方は開口部２４から入り上下のシ
ートの間にひろがり、パイプ２１・・・・・・・・・に
入り、その間を通って反対側の開口２４’から出る。One of the fluids to be heat exchanged enters through the opening 24, spreads between the upper and lower sheets, enters the pipe 21, passes therebetween and exits through the opposite opening 24'.
他方の流体は反対側の開口２５′から入り、上下のパイ
プ列の間を通り開口２５から出るようにすれば対向流型
の全熱交換を行なうものである。The other fluid enters from the opening 25' on the opposite side, passes between the upper and lower pipe rows, and exits from the opening 25, thereby performing counterflow type total heat exchange.
