Classification: CPC F | IPC F

Claim 0:
1. 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 refrigerant pipe side of the first plate-shaped portion,
wherein the first plate-shaped portion has a first opening that forms the refrigerant flow path,
wherein the second plate-shaped portion has second openings that form the refrigerant flow path,
wherein, when viewed in a stacking direction of the first plate-shaped portion and the second plate-shaped portion, the second openings and the first opening overlap each other at a first region and at a second region that is different from the first region,
wherein the first plate-shaped portion and the second plate-shaped portion are configured such that:
a refrigerant flows to the first plate-shaped portion from the second plate-shaped portion at the first region, the refrigerant flows to the second region from the first region at the first opening, and the refrigerant flows to the second plate-shaped portion from the first plate-shaped portion at the second region; or
the refrigerant flows to the first plate-shaped portion from the second plate-shaped portion at the second region, the refrigerant flows to the first region from the second region at the first opening, and the refrigerant flows to the second plate-shaped portion from the first plate-shaped portion at the first region,

wherein the first opening of the first plate-shaped portion includes a third region that overlaps a connection portion between the refrigerant pipe and the header when viewed in the stacking direction,
wherein the third region, the first region, and the second region are disposed side by side in a direction in which the heat transfer tubes are disposed side by side,
wherein a longitudinal direction of the header is a direction that is tilted in a range of ±45 degrees with respect to a horizontal direction or a horizontal plane of the heat exchanger, and
wherein the first opening of the first plate-shaped portion includes a connection region between the first region and the third region, 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 third region.
