Abstract: front page image
(EN)Provided is an optimum fin shape with excellent extrudability and heat exchange efficiency compared to conventional pipes having a straight grooved inner surface that uses an aluminum alloy. Specifically provided is a pipe having a grooved inner surface (100) made of an aluminum alloy, said pipe having a plurality of pointed fins (102) that are present on the inner surface of the pipe parallel to the longitudinal direction of the pipe; the shape and position of said plurality of fins (102) in a cross section orthogonal to the longitudinal direction of said pipe having a grooved surface (100) are roughly uniform in the circumferential direction of said pipe having a grooved surface (100); and the ratio between the length (F (mm)) of the inner peripheral edge in said cross section, and the area (A (mm2)) of the groove space section enclosed by circles that touch the inner peripheral edge and the tips of said plurality of fins (102) in said cross section is within a range of 10 ≤ F/A ≤ 15.
(FR)Le tuyau de cette invention comporte des ailettes permettant une excellente capacité à l'extrusion et une efficacité d'échange thermique très élevée, par rapport aux tuyaux de l'art antérieur comportant une surface interne à rainures rectilignes et mettant en oeuvre un alliage d'aluminium. Plus spécifiquement, l'invention concerne un tuyau (100) comportant une surface interne rainurée, en alliage d'aluminium, lequel possède plusieurs ailettes (102) sous forme de nervures situées en parallèle en direction longitudinale du tuyau, sur la surface interne de celui-ci. En section transversale par rapport à la direction longitudinale de ce tuyau (100) comportant une surface interne rainurée, la forme et l'emplacement des ailettes (120) est presque uniforme en direction circonférentielle du tuyau (100) comprenant une surface interne rainurée. En outre, en section transversale, le rapport entre la longueur (F) (mm) de la circonférence interne et la surface (A) (mm2) de l'espace interne des rainures entourée d'un cercle en contact avec la partie sommet des ailettes (120) et la circonférence interne, est le suivant: 10≤F/A≤15.
(JA) 従来のアルミニウム合金を用いた内面ストレート溝付管に比較して押出性及び熱交換効率に優れた最適なフィン形状を提供する。 管内表面に管の長手方向と並行に存在する突条型の複数のフィン102を持つアルミニウム合金製の内面溝付管100であって、該内面溝付管100の長手方向に直交する断面における該複数のフィン120の形状および配置が該内面溝付管120の円周方向で略均一であり、該断面における内周縁の長さF(mm)と該断面における内周縁及び該複数のフィン120頂部に接する円に囲まれた溝空間部の面積A(mm)との比が10≦F/A≦15の範囲内である、内面溝付管100を提供する。
