Abstract

PURPOSE: To form the joint of flat pipes of heat exchangers, etc. in a good fitting state through sure brazing by forming a cylindrical part and a drawn part in the end part of a flat pipe, fitting a tubular body clad with a brazing filler metal onto the drawn part and joining these by brazing in a furnace.
CONSTITUTION: A cylindrical part 3a, a drawn part 3b and an approximately horizontal step part 3b are formed in the end part of a flat tubular body 1 made of Al. A tubular body 1 clad with a brazing filler material 2 is fitted onto this drawn part 3b and its end face is abutted on the step part 3c. When these are loaded into a furnace and are heated, the brazing filler metal 2 on the surface of the tubular body 1 melts and flows into the contact part of both. At this time, the step part 3c blocks the flow of the brazing filler metal 2 and therefore the metal 2 forms a fillet 2c in the step part 3b, whereby the sure brazing is accomplished. By this method, fitting of the flat pipe to other tubular body is made easy, and the joint which is surely brazed with less possibility of loosening of the joint is formed.
