【０００３ 】
その内部の構造は、図６のＡ−Ａ断面拡大図である図７、図６のＢ−Ｂ断面拡大図である図８、及び各部材の斜視図である図９に示すように周囲に一段高い縁(25)を設けると共に２つのヘッダ（１、２）を挿入する２つの穴（23、24) を設けた第一隔離板（９）（図９のａ）と、低温流体流路（12）用のオフセットフィン型等の伝熱促進体（14) 及び2 個の斜流路部材（18、19）（図９のｂ) と、下記ヘッダ（１、２）を挿入する２つの穴（23、24) の周囲にエンボス部(22a、22b)を設けた第二隔離板（10）（図９のｃ）と、高温流体流路（13）用のオフセットフィン型等の伝熱促進体（15）及び２個の斜流路部材（20、21）（図９のｄ）とを繰り返して２段以上、多いものでは８０段以上に積み重ね、その上に第一隔離板（９）並びに低温流体流路（12）用の伝熱促進体（14）及び２個の斜流路部材（18、19) を重ね、最上部に下記ヘッダ（１、２）を挿入する穴（23、24) を設けた第三隔離板（11）（図９のｅ）を重ねて固定し、第一隔離板（９）と第二隔離板（10）の間及び第一隔離板（９）と第三隔離板（10）の間に補強材(26)を挿入し、低温流体流入用ヘッダ（１）及び加熱された低温流体流出用ヘッダ（２）を取付け、さらに上下にカバー（16、17）を固定したものである。
【０００３】
上記従来のプレート・フィン型熱交換器は、低温流体流入用ヘッダ（１）から低温流体流路（12）の斜流路部材（18）に入った低温流体（７）が、対向流部（４）で高温流体流路（13）の斜流路部材（20）の入口（５）から入った高温流体（８）によって加熱されて、低温流体流路（12）の斜流路部材（19）を通って低温流体流出用ヘッダ（２）から流出し、熱交換が終わった高温流体（８）は高温流体流路（13）用の斜流路部材の出口（６）から流出するようになっているものである。
なお、従来のプレート・フィン型熱交換器における低温流体流路（12）用及び高温流体流路（13）用の伝熱促進体として図９のｂ及びｄに示したようなオフセットフィン型のものを説明したが、ストレートのフィンの中にねじり板を入れたねじり板入りストレートフィン、フィンの通路を上下に波を打ったウエーブフィンも使用されており、上記従来のプレート・フィン型熱交換器は、これらのフィンを使用したものも含むものである。
【０００４】
【発明が解決しようとする課題】
上記従来のプレート・フィン型熱交換器の第三隔離板（11）は、図７及び図８に示すように１台の熱交換器に１枚使用しているだけであるが、その製造においては他の第一及び第二隔離板と同様に設計・製作する必要があるため、手間及び製作日数が必要であり、コストも高くなるという問題があった。
本発明は、第三隔離板として簡単に製造がすることができる形状の隔離板を使用したプレート・フィン型熱交換器及びその第三隔離板の製造方法を提供することを目的としているものである。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、本発明のプレート・フィン型熱交換器においては、従来のプレート・フィン型熱交換器の第三隔離板を第２隔離板のエンボス部を除いた形状と同一のものとし、最上部の第一隔離板と上のカバーとの間で、かつ低温流体流入用ヘッダ及び加熱された低温流体流出用のヘッダの周囲に低温流体の漏出を防止するリングを固定したことである。
また、本発明のプレート・フィン型熱交換器の第三隔離板の製造方法においては、第二隔離板のエンボス部を削除して製造することである。
【０００６】
【作用】
本発明においては、第三隔離板の形状を第二隔離板のエンボス部を除いたものと同一の形状としたことにより、第二隔離板のエンボス部のみを切除することにより製造することができるので、第三隔離板の形状をあらたに設計・製作する必要がないため、コストと製作日数を低減することができる。
また、最上部の第一隔離板と上のカバーとの間で、低温流体流入用ヘッダ及び低温流体流出用ヘッダの周囲にリングを溶接して固定したことにより、低温流体が漏出するのを防止することができる。
【０００７】
【実施例】
以下本発明の実施例について図１〜図４を参照して説明する。
実施例１
図１は本発明の一実施例のプレート・フィン型熱交換器の断面拡大図で、従来のものの図７に対応するものであり、図２は図１の熱交換器の第三隔離板の斜視図、図３は図２の第三隔離板の製造方法を示す説明図、図４は図１の熱交換器のリングの斜視図である。
【０００８】
本発明の上記プレート・フィン型熱交換器は、上記従来のプレート・フィン型熱交換器と同様に第一隔離板（９）の上に低温流体流路（12）用の伝熱促進体（14) 及び2 個の斜流路部材（18、19）をろう材を挟んだ後高温加熱してろう材を融解してろう付けて固定（以下、単に「ろう材を挟んで固定」と言う。）し、これの上に第二隔離板（10）の上に高温流体流路（13）用の伝熱促進体（15）及び２個の斜流路部材（20、21）をろう材を挟んで固定したものを乗せ、これらを繰り返して３層に積み重ね、その上に第一隔離板（９）の上に低温流体流路（12）用の伝熱促進体（14) 及び２個の斜流路部材（18、19）をろう材を挟んで固定したものを重ね、さらにその上に後から詳細に述べる第三隔離板（27）を重ね、各隔離板の外縁とこれに接している他の隔離板の外縁とを溶接して固定し、第一隔離板（９）と第二隔離板（10）との間及び第一隔離板（９）とカバー(17)との間に補強材(26)を挿入し、最上部の第一隔離板（９）と上のカバー（17）との間で、かつ低温流体流入用ヘッダ（１）及び低温流体流出用ヘッダ（２）が入る穴（23、24) を囲むように図４に示すリング（30a 、30b)を溶接して固定し、低温流体流入用ヘッダ（１）及び低温流体流出用ヘッダ（２）を取付け、さらに上下にカバー（16、17）を固定しろう付けして製造した。
【０００９】
上記第三隔離板（27）は、図２に示すようにヘッダ（１、２）を挿入する２つの穴（23、24) より大きい穴（28、29) が設けられたもので、図２及び図３に示すように第二隔離板（10）の穴（23、24）の周囲に設けられたエンボス部(22a、22b)を削除して製造したものである。
上記構造の本発明のプレート・フィン型熱交換器は、最上部の低温流体流路（12）が封鎖されるため、その分だけ従来のものより能力が低下したが、その他においては従来のものと相違するところがなかった。
なお、能力の低下は、層数が３層と少ない場合には１層多くすればよいし、層数が多い場合には無視することができるので問題がなかった。
【００１０】
上記実施例においては、プレート・フィン型熱交換器の低温流体流路（12）用及び高温流体流路（13）用の伝熱促進体として図９のｂ及びｄに示したようなオフセットフィンのものを用いているが、ストレートのフィンの中にねじり板を入れたねじり板入りストレートフィン、又はフィンの通路を上下に波を打つたウエーブフィンも同様に使用することができる。
【００１１】
【発明の効果】
本発明は、プレート・フィン型熱交換器の第三隔離板（27）を第二隔離板（10）のエンボス部(22a、22b ）を切除した形状と同一のものとしたため、第二隔離板（10）のエンボス部（11）を削除して製造することがてきるので、設計及び製作の手間及び日数を少なくすることができ、その結果、コスト及び製作日数を低減できるという優れた効果を奏する。
