Abstract
【解決手段】コルゲートフィンとするとともに湾曲部6に係合凹部8を形成した複数のフィン部材3と、このフィン部材3を介して配置した直管部2をU字状の折返し部5で連結した管部材1とから成る。そして、上記直管部2を上記フィン部材3の係合凹部8に係合した状態において、管部材1の外径を8mm〜12mmとし、フィン部材3の対向間隔17を0.5〜5.0mmとする。また、上記フィン部材3の突出高さを、11mm以下、且つ上記対向間隔17が0.5〜5.0mmの範囲内で、y≧2.46x-0.29 (y:管部材1表面からのフィン部材3の突出高さ/湾曲頂部15の対向間隔17、x:湾曲頂部15の対向間隔17)の数式が成立する値とした。

Description
η=tanh(mL)/mL m≡(2h/kδt)1/2×L
η:フィン効率(%)
k:熱伝導率(標準的なアルミ合金として約150w/mK)
h:熱伝達係数(曲げ平面垂直;約60w/m2K、曲げ平面平行;約25w/m2K)
L:フィン部材の突出高さ(mm)
δt:フィン部材の板厚(0.3mm)
にて計算を行った。この計算結果を基に作成したグラフを図2に示す。尚、上記フィン効率とは、フィン部材の形状、フィン部材の高さ、フィン部材の板厚により変化するフィン部材の放熱効率を意味するものであり、図2の結果は、フィン部材の形状、密度、及びフィン部材の板厚を一定とし、フィン部材の高さのみを3〜13.5mmに変化させた場合のフィン効率の変化状況を表したものである。
