ABSTRACT:
In an end-closed pipe of a pair of half-cylindrical portions are opposed to each other to form a pipe portion, and part of an end portion of each of the half-cylindrical portions is folded or formed into a V-shaped or a U-shaped cross-section to form a half closure portion projecting from an inner surface thereof, and the half closure portions of the two half-cylindrical portions are bonded together so as to form a closure portion at the end portion of the pipe. Two closure portions are formed at the both ends of the pipe, and a partition portion which has same structure as that of the closure portion is formed between the two closure portions. In the heat exchanger header a plurality of tube insertion holes are formed in the above end-closed pipe, and are spaced from one another along an axis thereof.
