PROBLEM TO BE SOLVED: To suppress cutting or damage such as breakage or the like of a heat exchanging pipe near a header pipe mounting position by penetrating a bar-like element passing through the exchanging pipe also via the header pipe, and fixing an opposite side face to the heat exchanging pipe mounting side to the header pipe. SOLUTION: An opening 18 is perforated at a lower surface side of a header pipe 12, and a heat exchanging pipe mounting fixture 21 is mounted in the opening 18. A box nut 22 in which a heat exchanging pipe 15 made of a fluororesin is inserted into its center is threaded with an opposite side of the fixture 21 to the pipe 12 to mount the pipe 15 at the pipe 12. Further, a bar-like element 23 is penetrated along the pipe 15, passed through the nut 22 and the fixture 21, and then penetrated to the pipe 12. A box nut 25 in which the element 23 is inserted at its center is threaded with a bar-like element locking implement 24 mounted at an upper surface side of the pipe 12, and the element 23 is effectively fixed to the pipe 12. |
