摘要： This laminated header (2) is provided with a first plate-shaped body (11) in which a plurality of first exit channels (11A) are formed and a second plate-shaped body (12) attached to said first plate-shaped body (11). Distribution channels (12A) via which a refrigerant flowing in via a first entrance channel (12a) is distributed to and flows out via the first exit channels (11A) are formed in the second plate-shaped body (12). Said distribution channels (12A) include forked channels (12b) that each have an opening, a first straight section parallel to the direction of gravity, and a second straight section parallel to the direction of gravity, with the bottom end of the first straight section connecting to the opening via a first connecting section and the top end of the second straight section connecting to the opening via a second connecting section. At least part of each first connecting section is not parallel to the direction of gravity, as is at least part of each second connecting section. In each forked channel (12b), the refrigerant flows into the bottom end of the first straight section and the top end of the second straight section from the opening via the first and second connecting sections and flows out from the top end of the first straight section and the bottom end of the second straight section.

摘要： Plate-shaped fins 3 of a heat exchanger 4 each include, at circumferential portions thereof defining a notch 2 in which a heat transfer tube 1 having a flattened shape is disposed, fin collars 5 formed by being raised from the circumferential portions. Each of the fin collars 5 includes, in a position that faces a long axis side surface of the heat transfer tube 1, at least one reflare section 6 bent in a direction opposite to the side surface. At least one of the reflare sections 6 defining fin pitches between the adjoining plate-shaped fins 3 is formed so that a reflare tip portion 6b, which is a tip portion of the reflare section 6, is drawn apart from a contact side surface of the plate-shaped fin 3 with which the reflare section 6 comes into contact.
