ト。 A large number of cylindrical portions 2 each having a tapered circumferential surface are integrally formed on a band-shaped metal plate 1 by plastic working, spaced apart from each other in the longitudinal direction, and a plurality of the metal plates 1, 1 are laminated. In the element of the tubeless heat exchanger in which the inner and outer surfaces of the cylindrical part 2 are in contact with each other and fixed by brazing liquid-tightly, the cylindrical part 2 is formed flat, and the long axis of its cross section is Cuts 3 for drawing in material are formed in the metal plate 1 in advance parallel to the long axis in the vicinity of both sides of the short axis of the cylindrical portion 2, which are positioned parallel to the width direction of the metal plate 1.
An element for a tubeless heat exchanger, characterized in that the cylindrical portion 2 is formed so as to prevent cracks from forming on the circumferential surface thereof during plastic working of the cylindrical portion 2.
