Abstract
(EN)
Heat exchange efficiency is improved by combining heat exchange units into a rectangular shape and increasing the mounting area, said heat exchange units having: a plurality of plate fins (140) lined up at prescribed intervals and having air flowing therebetween; and a plurality of flat tubes (150) that are inserted into the plate fins (140) such that refrigerant flows inside the tubes along the arrangement direction of the plate fins (140), said flat tubes being formed into an L-shape by a bending process.
(FR)
L'efficacité de l'échange de chaleur est améliorée en combinant des unités d'échange de chaleur dans une forme rectangulaire et en augmentant la surface de montage, lesdites unités d'échange de chaleur présentant : une pluralité de plaques-ailettes (140) alignées à intervalles prescrits, de l'air circulant entre ces dernières ; et une pluralité de tubes plats (150) qui sont insérés dans les plaques-ailettes (140) de telle sorte que le fluide frigorigène circule à l'intérieur des tubes le long de la direction d'agencement des plaques-ailettes (140), lesdits tubes plats étant formés pour avoir une forme de L par un procédé de flexion.
