Semifinished flat tube 30 for manufacture flat tube 1 include upper and lower wall 2,3 opposite one another, and interconnect upper lower wall 2,3 over there in edge with right opposite side wall 4,5. Semifinished flat tube manufactures the tool of metal plate 15, and there are two flat first parts 17,18, for making upper lower wall 2,3, it is outstanding upwards from corresponding first part 153,154 and the first disc portion respectively in its side and second part for making left side wall 155 156 that second part 16 interconnects the whole part 151,152 for being used to form right side wall 5 and 150 of Liang Ge first parts 17,18, by by the shape of the hair clip of metal plate 157, to cause in second part and third portion 158,159,170, so as to against each other. Two Part III 9,10 are connected to each other, intermittently with laser welding from outside multiple in longitudinally spaced portion.
