Abstract (en)
In a stacking type header 10, in a state in which flat tubes 20 are inserted into openings 12A in a bare member 12 and in which ends 20A of the flat tubes 20 are in contact with stoppers 12B, spaces 30 are formed at positions surrounded by the flat tubes 20, a clad member 11, and the bare member 12. The spaces 30 each include a first space 30a formed in a vicinity of a contact boundary surface between the flat tube 20 and the clad member 11, a second space 30b smaller than, at least, the first space 30a and formed in a vicinity of a contact boundary surface between the bare member 12 and the clad member 11, and a third space 30c smaller than, at least, the first space 30a and formed in a vicinity of a contact boundary surface between the bare member 12 and the flat tube 20.
