Abstract:
This heat exchanger includes: a first heat exchanger having a first intermediate header extending in the direction of gravity, a first heat transfer tube connected to the first intermediate header and performing heat exchange between a refrigerant and air, and a first partition partitioning the inside of the first intermediate header into a first space and a second space disposed below the first space; and a second heat exchanger provided side-by-side with and upwind of the first heat exchanger and having a second intermediate header extending in the direction of gravity, a second heat transfer tube connected to the second intermediate header and performing heat exchange between a refrigerant and air, and a second partition partitioning the inside of the second intermediate header into a third space and a fourth space disposed below the third space. The first heat transfer tube is provided in a plurality, and the plurality of first heat transfer tubes include a first heat transfer tube connecting to the first space, and a first heat transfer tube connecting to the second space. The first intermediate header constituting the first space is provided with a first outflow port from which the refrigerant flows out, and the first intermediate header constituting the second space is provided with a second outflow port from which the refrigerant flows out.
