PROBLEM TO BE SOLVED: To provide a header for a heat exchanger which has excellent assemblability and reliability.SOLUTION: A cylindrical second header collection tube 50 extending along a longitudinal direction includes: a central vertical member 70 extending along the longitudinal direction; a right side enclosure member 60 for forming a right side space RS together with the central vertical member 70; and a left side enclosure member 65 for forming a left side space LS together with the central vertical member 70. The central vertical member 70 includes: a first flange 72 for covering a right side enclosure member rear end part 601 and a left side enclosure member rear end part 651 from outside; and a second flange 73 for covering a right side enclosure member front end part 602 and a left side enclosure member front end part 652 from outside. The right side enclosure member 60 and the left side enclosure member 65 are joined to the central vertical member 70 in a state where the right side enclosure member rear end part 601 or the left side enclosure member rear end side 651 is opposing to the inner surface of the first flange 72 and the right side enclosure member front end part 602 or the left side enclosure member front end part 652 is opposing to the inner surface of the second flange 73.SELECTED DRAWING: Figure 17 |
