Description
(1)作動圧力の高い二酸化炭素冷媒を使用する内面溝付管において、管内面にフィンが形成され、拡管前の第一のフィンが高さ0.10〜0.22mm、及び頂角が20〜60度、第二のフィンの頂角が20〜60度であり、第二のフィンの高さと第一のフィンの高さとの比が0.5〜0.9であり、管の肉厚tは0.4〜1.0mmで、且つ管の外径Dとの比t/Dが0.04〜0.25の範囲内であるとともに、第一のフィンの頂部が平面であり、該頂部の平面部の幅とフィン高さとの比が0.3〜1.0の範囲内であることを特徴とする熱交換器用内面溝付伝熱管
(2)(1)記載の内面溝付伝熱管を用いた熱交換器を提供するものである。
リン脱酸銅(JIS C 1200)からなる管を転造加工することにより表1記載の伝熱管を製造し、拡管前の伝熱性能として熱伝達率を測定した。次いで前記伝熱管を拡管プラグにより拡管してアルミフィンへの装着を行い、内面フィンの倒れの有無、アルミフィンの割れ有無について評価した。さらに、前記伝熱管をアルミフィンから取りはずして、拡管後の伝熱性能として熱伝達率を測定した。なお比較例6を除いて外径Dを7mm、肉厚tを0.6mm、内面フィン総数を60、ねじれ角度を10度、第二のフィンの頂角γ2を25度とした。比較例6は平滑管であり、管内面に溝は無い。
