Abstract
【解決手段】対峙する一対のヘッダーパイプ2a,2b間に、互いに平行な複数の扁平状熱交換チューブ3を水平方向に配置し、山−谷折りを交互に繰り返して成形されたコルゲートフィン4を熱交換チューブ3間に接合してなり、熱交換チューブ3の幅方向の端部に延設される鍔部を傾斜状に切り起こした切起し片8にて流水路10を形成してなるコルゲートフィン式熱交換器において、各熱交換チューブ3に形成される複数の切起し片8を熱交換チューブ3の長手方向に沿って適宜間隔をおいて列設すると共に、コルゲートフィンの山頂点と谷頂点間のピッチ(P)と、切起し片の上下方向の幅(L)と、熱交換チューブの厚さ(T)との関係を、P×2≧L≧Tとする。
【選択図】図1
Description
P×2≧L≧Tで表すことができる。また、熱交換チューブ3の中心線に対する切起し片8の角度をθとすると、
L×sinθ=Tで表すことができる。
次に、この発明における熱交換チューブ3,コルゲートフィン4及び切起し片8の各部の寸法/角度の最適範囲を調べるための評価試験について説明する。
2a,2b ヘッダーパイプ
3 熱交換チューブ
4 コルゲートフィン
4a フィンルーバ
7 鍔部
8 切起し片
9 肉厚部
10 流水路
P コルゲートフィンのピッチ
L 切起し片の幅
T 熱交換チューブの厚さ
θ 切起し片の角度
また、この発明において、最下端の上記コルゲートフィンの下部開放側に接合されるサイドプレートを具備し、上記サイドプレートの中央部に、該サイドプレートの長手方向に沿う排水用スリットを設けるのが好ましい。また、これに代えて、上記サイドプレートは、上記コルゲートフィンに接触する水平片と、該水平片の一端部から直交状に屈曲する垂下片とからなり、上記垂下片に、上記サイドプレートの長手方向に沿って間隔をおいて垂下片の下端から上記水平片の交差部に渡って上記コルゲートフィンのピッチより狭い幅の排水用溝を形成するのが好ましい。
このように構成することにより、最下端部のコルゲートフィン間に滞留する水を下方へ排水することができる。
