Abstract
【解決手段】コイル組立体は、ハウジングのコイル組立体領域に配置されてほぼ等間隔に離間する複数の蛇行管路のアレイから構成され、隣接する複数の返しベンドを重ねて平行にずれた形態で隣接する複数の蛇行管路が配置される。蛇行管は、有効直径を有する。重なり位置に凹部領域を設けて、重なり位置での直径が部分的に減少させる。凹部領域は、内部流体の最小圧力降下を僅かに増加させるが、所定の大きさに制約されて適用する場合でも、付加的な管路を追加できるため、熱伝達表面積が増大する。内部流動領域の増大により減少する内部流体の圧力降下により、増加する圧力降下を十分に相殺できる。本発明のコイル組立体は、種々の型式の熱交換器に有用である。
【選択図】図8
Description
本発明の例示的な実施の態様では、管路上の所望の全領域にほぼ同時に窪みを形成する金型又はジグによって、複数の窪みを同時に形成してもよい。別法として、蛇管返しベンドを形成する間に、各窪みを形成することもできる。使用する特定の管形成法に基づき、窪みの特定の形成法を選択できる。
本発明のコイル組立体の構成は、間接蒸発式熱交換器、空冷式熱交換器、蓄熱装置並びにシェルチューブ式熱交換器を含むが、これらに限定されず、異なる多型式の熱交換器にも適用できる。間接蒸発式熱交換器は、空気流と、蒸発性液体流と、液体又は気体である密封流体流との3つの流体を含む。密封流体流は、最初に蒸発性液体に直接接触せず、間接式熱伝達によって、蒸発性液体と熱交換し、次に、蒸発性液体及び空気流は、互いに直接接触して、蒸発による熱交換を行う。直接蒸発式熱交換器では、空気流及び蒸発性液体流のみを使用して、空気流及び蒸発性液体流を互いに直接接触させて、蒸発による熱交換を行う。蒸発性液体は一般に水である。
1.q=A(tc−ts)Us、及び
2.q=A(hs−hl)Uc
ここで、q=全熱伝達量、A=全管表面積、tc=管内流体温度、ts=管外水温、Us=水に対する流体の熱伝達係数、hsは、tsでの飽和空気のエンタルピー、hl=周囲空気のエンタルピー、及びUc=空気に対する水の熱伝達係数である。
