Abstract
(EN)
This heat exchanger includes: a plurality of tubes (20) arranged in one direction (DRst) through which a first fluid flows; a corrugated fin (10) provided between the tubes for promoting heat exchange between the first fluid and a second fluid flowing between the tubes; and a fillet part (30). The corrugated fin has a plurality of crests and a plurality of troughs to form a corrugated shape where the crests and troughs are arranged alternately and connected. The fillet part comprises a joining material joining the corrugated fin to the tubes, and is in contact with the corrugated fin and the tubes. The corrugated fin has a surface (10a) where a groove (101) extending in the above-described one direction is formed, the groove having a groove width (Wd) which is less than a one-direction spacing (GL) between a heat-transfer promoting part (14) of the corrugated fin having a cut-and-raised shape and the tubes. The fillet part is located within a range occupied by the one-direction spacing in the above-described one direction, and the width (Wf) of the fillet part in the above-described one direction is less than the one-direction spacing.

La présente invention concerne un échangeur de chaleur comprenant : une pluralité de tubes (20) agencés dans une direction (DRst) à travers laquelle s'écoule un premier fluide ; une ailette ondulée (10) agencée entre les tubes afin de favoriser un échange de chaleur entre le premier fluide et un second fluide s'écoulant entre les tubes ; et une partie congé de raccordement (30). L'ailette ondulée comporte une pluralité de crêtes et une pluralité de creux destinés à lui donner une forme ondulée, les crêtes et les creux étant agencés en alternance et reliés. La partie congé de raccordement comprend un matériau de liaison reliant l'ailette ondulée aux tubes, et en contact avec l'ailette ondulée et les tubes. L'ailette ondulée comporte une surface (10a) dans laquelle une rainure (101), s'étendant dans la direction susmentionnée, est formée, la rainure présentant une largeur de rainure (Wd) inférieure à un espacement unidirectionnel (GL) entre une partie (14), favorisant le transfert de chaleur de l'ailette ondulée présentant une forme découpée et surélevée, et les tubes. La partie congé de raccordement est située à l'intérieur d'une plage occupée par l'espacement unidirectionnel dans la direction susmentionnée, et la largeur (Wf) de la partie congé de raccordement dans la direction susmentionnée est inférieure à l'espacement unidirectionnel.

熱交換器は、一方向(DRst)に並び第1流体が流れる複数本のチューブ(20)と、チューブ相互間に設けられ第1流体とチューブ相互間に流れる第2流体との熱交換を促進するコルゲートフィン(10)と、フィレット部(30)とを備える。コルゲートフィンは、複数の頂部と複数の谷部とを有し、その頂部と谷部とが交互に並んで連結された波形状を成している。フィレット部は、コルゲートフィンをチューブに接合する接合材で構成され、コルゲートフィンとチューブとに接する。コルゲートフィンの表面(10a)には、上記一方向へ延びる溝(101)が形成され、その溝の溝幅(Wd)は、コルゲートフィンのうち切り起こされた形状の伝熱促進部(14)とチューブとの間の一方向間隔(GL)よりも小さい。フィレット部は、一方向間隔が上記一方向に占める範囲内に位置し、上記一方向におけるフィレット部の幅(Wf)は一方向間隔よりも小さい。
