Abstract

PURPOSE:To facilitate connection of a fluid passageway tube with a header, as well as to prevent the tube from distortion and its pressure rolled surface from breakage, by pinching a fluid passageway tube made of copper material by a fin part made of aluminum material, and by expanding the tube after it is pressure- rolled into a flat form by a cold rolling under the same pressure rolling rate, and by providing projection parts on both ends of the tube. CONSTITUTION:The upper surface of an aluminum plate 1, the outer surface of a copper tube 2', and the under side of an aluminum plate 3 are respectively roughed by a brush 14, and at the same time, deposited foreign matters are removed from them. A releasant is previously put on the inside surface of a copper tube 2' to prevent it from being pressure-rolled to each other. A pressure- rolled plate 18 is rolled up by a cold pressure roller 16 having a groove 17 on its surface, at one passing under the uniform pressure-rolling rate, as a whole. Next, the pressure rolled plate 18 is cut into single body in the center of an unrolled part 19, and is pinched in a fitting strip 20. The tip of a nozzle 21 is inserted into a detached end part of a flat copper tube 2, into which the fluid pressure is introduced to expand the flat copper tube 2 to form a fluid passageway tube. The unrolled end part 19 is cut off to expose the end of a fluid passageway tube 7 and a product is obtained.

That is, the non-crimped part of the cut material is cut at 6, the end of the flat copper material pipe is made to protrude, and then it is crimped with a peeling agent for the flat copper pipe 111. In order to introduce the fluid into the inner surface where the fluid is not present, the flat copper honing tube may be expanded to form a fluid passage, or the flat copper honing tube may be formed into a film from the rolling play state to introduce the fluid. After forming a passage, use the C non-pressure shield part to protrude the end of the C fluid passage pipe.
