Abstract
(EN)
A parallel flow type heat exchanger in which the heat exchange performance is enhanced and defrosted water or condensate can be drained smoothly. The heat exchanger (1) includes horizontal header pipes (2, 3) arranged in parallel while spaced apart in the vertical direction, a plurality of vertical flat tubes (4) arranged between the header pipes (2, 3) while spaced apart in the horizontal direction and communicating a vertical refrigerant passage (5) internally provided with the interior of the header pipe, and a corrugate fin (6) arranged between the flat tubes (4). The corrugate fin (6) consists of a windward side corrugate fin (6U) having a fin surface of down grade toward the leeward side, and a leeward side corrugate fin (6D) having a fin surface of up grade toward the leeward side. On the side face of the flat tube (4), a vertical rib (12) is formed for making the leeward side end of the windward side corrugate fin (6U) abut on the windward side end of the leeward side corrugate fin (6U).

L'invention concerne un échangeur de chaleur de type à écoulement parallèle, dans lequel les performances d'échange de chaleur sont améliorées et l'eau dégelée ou le condensat peuvent être évacués sans à-coups. L'échangeur de chaleur (1) comprend des tuyaux collecteurs horizontaux (2, 3) disposés en parallèle tout en étant espacés dans la direction verticale, une pluralité de tubes plats verticaux (4) disposés entre les tuyaux collecteurs (2, 3) tout en étant espacés dans la direction horizontale et en communiquant avec un passage de fluide frigorigène vertical (5) disposé de façon intérieure à l'intérieur du tuyau collecteur, et une ailette ondulée (6) disposée entre les tubes plat (4). L'ailette ondulée (6) consiste en une ailette ondulée côté au vent (6U) ayant une surface d'ailette en pente vers le côté sous le vent, et une ailette ondulée côté sous le vent (6D) ayant une surface d'ailette en pente ascendante vers le côté sous le vent. Sur la face latérale du tube plat (4), une nervure verticale (12) est formée pour amener l'extrémité côté sous le vent de l'ailette ondulée côté au vent (6U) à venir en butée sur l'extrémité côté au vent de l'ailette ondulée côté sous le vent (6U).
