Classification: CPC F | IPC F

Claim 2:
3. A heat exchanger connected to a refrigerant pipe, the heat exchanger comprising:
heat transfer tubes; and
a header that connects the refrigerant pipe and the heat transfer tubes, and that forms a refrigerant flow path between the refrigerant pipe and the heat transfer tubes,
wherein the header includes a first member that includes a first plate-shaped portion, and a second member that includes a second plate-shaped portion that is stacked on a heat transfer tubes side of the first plate-shaped portion,
wherein the first plate-shaped portion forms the refrigerant flow path and has a first opening that extends in a longitudinal direction of the first member,
wherein the second plate-shaped portion has flow-dividing openings that form the refrigerant flow path,
wherein the first opening includes an introduction region, a connection region, and a blowing region that are disposed side by side in a direction in which the heat transfer tubes are disposed side by side,
wherein the blowing region overlaps and communicates with the flow-dividing openings when viewed in a stacking direction of the first plate-shaped portion and the second plate-shaped portion,
wherein the introduction region overlaps a connection portion between the refrigerant pipe and the header when viewed in the stacking direction of the first plate-shaped portion and the second plate-shaped portion,
wherein a width of the connection region in a direction perpendicular to both the direction in which the heat transfer tubes are disposed side by side and the stacking direction is smaller than the introduction region and is smaller than the blowing region,
wherein a longitudinal direction of the blowing region is the longitudinal direction of the first member, and
wherein the flow-dividing openings of the second plate-shaped portion are aligned along the longitudinal direction of the blowing region.
