Description
図1乃至図4に示すように、本発明に係る熱交換器1は、中心軸Oを共通として同軸配置した内装管2と外装管3とから成る二重管構造を有し、内装管2の外周面2aと外装管3の内周面3b間に軸方向に沿って横断面形状が環状の環状流路4を形成すると共に、該環状流路4内に軸方向に沿ってコイル管5を配して螺旋状流路6を形成する基本構成を有している。本発明に係る熱交換器1の軸方向は上下方向でも左右方向でも良い。すなわち熱交換器1を縦置きしても横置きしても良い。
内装管2はステンレス等の金属から成る円管であり、例えば内径が54.9mm、外径が60.5mm、周壁厚が2.8mmである。該内装管2は、図4に示すように、内周面2bに囲まれた内部2cを有しているが、本発明において、この内部2cはブラインや水素ガスの流路としては用いない。つまり内装管2の内部2cは環状流路4にも螺旋状流路6にも通じていない。
外装管3はステンレス等の金属から成る円管であり、組立容易性及びコイル管5の挿抜のために、三つの分割された管から構成される。既述の内装管2の寸法例示に対して、例えば内径が108.3mm、外径が114.3mm、周壁厚が3.0mmに設定する。
コイル管5は、既述の内装管2及び外装管3の寸法例示に対して、例えば内径が4.93mm、外径が9.53mm、周壁厚が2.3mmの円管をコイル平均径(コイル外径とコイル内径との平均)87.2mmでコイルピッチ16.18mmとなるように設定し、螺旋状に巻いて形成する。該コイル管5の構成材としては、例えばオーステナイト系ステンレス鋼等のNi当量値が28.5%〜32.09%で引張強度が800N以上の鋼材が望ましい。コイル状に成形(変形)されるコイル管自体の周壁厚を可及的に薄くできると共に、水素ガスに対して耐性が高いためである。
図4乃至図6に示すように、環状流路4はコイル管5よりも外側の外側環状流路4Aと、コイル管5よりも内側の内側環状流路4Bとに分かれる。よってブラインは外側環状流路4A内と内側環状流路4B内へと分流し、コイル管5、ひいては螺旋状流路6を挟みつつ流れることとなる。
Claims (6)
- 同軸配置した内装管と外装管から成る二重管構造を有し、該内装管の外周面と該外装管の内周面間に軸方向に沿って環状流路を形成すると共に、該環状流路内に軸方向に沿ってコイル管を配して螺旋状流路を形成する傍ら、上記内装管の内部には流路を形成しない構成を具備し、上記環状流路において、上記コイル管より外側の外側環状流路の横断面積と、該コイル管よりも内側の内側環状流路の横断面積とが同一となるように上記コイル管のコイル平均径を設定し、上記環状流路内を一定方向に流れる冷却流体と上記螺旋状流路内を一定方向に流れる被冷却流体間で熱交換を行うことを特徴とする熱交換器。
- 上記冷却流体が流れる向きは上記被冷却流体が流れる向きに対して向流であることを特徴とする請求項1記載の熱交換器。
- 上記コイル管は上記環状流路内に挿抜可能に配されることを特徴とする請求項1又は請求項2に記載の熱交換器。
- 上記コイル管のコイル平均径は当該コイル管の外径の4倍以上であることを特徴とする請求項1乃至請求項3の何れかに記載の熱交換器。
- 上記コイル管に軸方向に沿って当該コイル管の全体形状及びコイルピッチを保つ保形材を設けることを特徴とする請求項1乃至請求項3又は請求項5の何れかに記載の熱交換器。
- 上記内装管の内部又は/及び上記外装管の外部に断熱材を配することを特徴とする請求項1乃至請求項3又は請求項5又は請求項6の何れかに記載の熱交換器。
