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。
