LAMINATED HEADER, HEAT EXCHANGER, AND AIR CONDITIONING DEVICE

摘要

This laminated header (3) comprises: a first plate-shaped body in which a first inlet flow path and a first outlet flow path are formed; and a second plate-shaped body that is attached to the first plate-shaped body, and in which at least a portion of a first passage flow path, which allows the passage of a refrigerant flowing in from the first inlet flow path, and at least a portion of a second passage flow path, which allows the passage of the refrigerant to the first outlet flow path, are formed. The end of the first passage flow path on the side that is not connected to the first inlet flow path and the end of the second passage flow path on the side that is not connected to the first outlet flow path are connected via a first pipe, and thereby a first fold-back flow path is formed.
