Abstract (en)

[origin: EP4235058A1] A heat exchanger (100) includes a first heat exchange portion (11) and a second heat exchange portion (12) that are arranged side by side in a Y direction intersecting with a direction of gravity. The first heat exchange portion includes a plurality of first fins (1) and a plurality of first flat tubes (2), the first flat tubes being arranged side by side in the direction of gravity. The second heat exchange portion includes a plurality of second fins (3) and a plurality of second flat tubes (4), the plurality of second flat tubes (4) being arranged side by side in the direction of gravity. The heat exchanger further includes: a first header (13) connected to a first end of each of the first flat tubes; a second header (14) connected to a first end of each of the second flat tubes; and a third header (15) connected to each of the first flat tubes and each of the second flat tubes. When viewed in a Y direction, each of the second flat tubes is disposed not to overlap with each of the first flat tubes. The third header includes: a first plate (15A) provided with a plurality of first insertion holes (16) through which the second ends of the first flat tubes are respectively inserted and a plurality of second insertion holes (17) through which the second ends of the second flat tubes are respectively inserted; and a second plate (15B) provided with a plurality of communication spaces (18) each communicating with a corresponding one of the first insertion holes and a corresponding one of the second insertion holes.
