ABSTRACT:
A tube101is constituted by a pair of plates111a,111bwhich are fitted with each other in such a manner as to put an inner fin101bbetween the plate111aand the plate111b. Differences in level111care formed on the second plate111b, which fits inside, which differences in level each protrude inwardly by a distance equal to the thickness of the first plate111a, whereby the outer wall surface of the tube101is made substantially level thereover. A gap which is formed between the outer wall surface of the tube101and a core plate, when the tube is passed through the core plate, can be as small as possible whereby the brazing properties can be improved.
