Abstract (en)

To provide a tube for a heat exchanger, which is formed by folding a metal strip plate (P) into two and brazing joint portions (22), (22) formed at either end of the plate (P) in its breadth direction, and a groove (21a) is formed along a portion-to-be-folded (21') of the plate (P) in a longitudinal direction of the plate (P). Thus, the plate for the tube can be folded accurately and easily. As a result, brazing property is improved. <IMAGE>
