Abstract (en)
[origin: WO9902283A1] A tube for heat exchangers, in which a band-shaped metallic plate (P) is bent and joint portions (22) provided on both ends of the plate (P) in the widthwise direction are brazed to each other. The tube has a groove (21a) extending lengthwise of the plate (P) and formed on a portion (21') where the plate (P) is to be bent. Accordingly, it is possible to correctly and easily bend the plate with the result that a brazing performance is improved.
