ABSTRACT:
A plurality of first joint tubes40connected to a plurality of heat transfer tubes3and a plurality of second joint tubes50provided at a header5B are connected to each other at joints J. The joints J include at least one slide joint Ja at which respective ends of the first and the second joint tubes40and50are fitted to each other slidably in a predetermined direction. The joints J further include at least one butt joint Jb at which an end of either one of the first and the second joint tubes butts against a sealing surface provided at the other one of the first and the second joint tubes. The butt position of the sealing surface and the end is variable in a direction crossing the predetermined direction. With this arrangement, the influence of an error in the arrangement of the first and the second joint tubes40and50is reduced, so that the header5B is properly connected to the heat transfer tubes3detachably, and the maintenance of the heat exchanger HE is facilitated.
