Abstract:
(EN) Provided is a heat exchanger having: a plurality of flat tubes arranged at a distance from each other such that the flat surfaces of the flat tubes are parallel to each other; and corrugated fins each sandwiched between a respective pair of adjacent one and the other of flat tubes of the plurality of flat tubes. The corrugated fins each have: first joining sections which are protrusions on one side of the corrugated shape and which are connected to a flat surface of said flat tube; second joining sections which are protrusions on the other side of the corrugated shape and which are connected to a flat surface of the other flat tube; and fin sections which, between the first joining sections and the second joining sections, exchange heat with air. The fin sections have: fin surfaces for connecting the first joining sections and the second joining sections; slits open longitudinally in the direction along the flat surfaces, between the first joining sections and the second joining sections; and sloped sections continuous from the vicinities of the first joining sections or the vicinities of the second joining sections to the slits and having different gradients relative to the fin surfaces. When the direction in which the plurality of flat tubes extend is vertical, the sloped sections are sloped downward from the first joining section side or the second joining section side toward the slits.
(FR) L'invention concerne un échangeur de chaleur comportant : une pluralité de tubes plats disposés à une certaine distance les uns des autres de sorte que les faces plates des tubes plats soient parallèles les unes aux autres ; et des ailettes ondulées intercalées chacune entre un tube plat et un autre tube plat adjacents parmi la pluralité de tubes plats. Les ailettes ondulées comportent chacune : des premières sections d'assemblage prenant la forme de saillies sur un côté de la forme ondulée et reliées à une face plate dudit tube plat ; des secondes sections d'assemblage prenant la forme de saillies sur l'autre côté de la forme ondulée et reliées à une face plate de l'autre tube plat ; et des sections d'ailette destinées à échanger de la chaleur avec l'air, entre les premières sections d'assemblage et les secondes sections d'assemblage. Les sections d'ailette comportent : des faces d'ailette destinées à relier les premières sections d'assemblage et les secondes sections d'assemblage ; des fentes ouvertes longitudinalement dans la direction le long des faces plates, entre les premières sections d'assemblage et les secondes sections d'assemblage ; et des sections inclinées s’étendant de manière continue depuis le voisinage des premières sections d'assemblage aux fentes ou du voisinage des secondes sections d'assemblage aux fentes et présentant des gradients différents par rapport aux faces d'ailette. Lorsque la pluralité de tubes plats s'étendent dans la direction verticale, les sections inclinées s'inclinent vers le bas à partir du côté de la première section d'assemblage vers les fentes ou à partir du côté de la seconde section d'assemblage vers les fentes.
(JA)  熱交換器は、それぞれの扁平面が平行となるように間隔を空けて並ぶ複数の扁平管と、複数の扁平管の隣り合う一方の扁平管と他方の扁平管との間に挟まれるコルゲートフィンと、を有し、コルゲートフィンは、コルゲート形状の一方の凸部で一方の扁平管の扁平面と接合した第1の接合部と、コルゲート形状の他方の凸部で他方の扁平管の扁平面と接合した第2の接合部と、第1の接合部と第2の接合部との間で空気と熱交換するフィン部と、を有し、フィン部は、第1の接合部と第2の接合部との間をつなぐフィン面部と、第1の接合部と第2の接合部との間で、扁平面に沿った方向に長手に開口されたスリットと、第1の接合部又は第2の接合部の近傍からスリットまでの間に連続してフィン面部に対して異なる傾斜を有する傾斜部と、を有し、複数の扁平管が延びる方向を垂直としたときに、傾斜部が、第1の接合部側又は第2の接合部側からスリットに向かって下り傾斜となっている。
