摘要： A heat exchange unit includes: a heat exchanger in which flat tubes are stacked at predetermined intervals in a thickness direction by a heat transfer fin; and a first member that is attached to the heat exchanger and that restricts a movement of the heat exchanger. The first member includes a body and a protrusion portion protruding from the body. The protrusion portion is disposed between adjacent flat tubes of the heat exchanger.

摘要： A heat exchanger that exchanges heat between a refrigerant and air, includes: flat tubes disposed in a first direction intersecting with a longitudinal direction of cross sections of the flat tubes and through which the refrigerant flows; first heat transfer fins that contact the flat tubes and are disposed on a windward side of the flat tubes; and second heat transfer fins that contact the flat tubes and are disposed on a leeward side of the flat tubes. The first heat transfer fins are inserted toward the flat tubes from a side of first ends in the longitudinal direction. The second heat transfer fins are inserted toward the flat tubes from a side of second ends in the longitudinal direction.

摘要： A heat transfer tube includes first flow paths aligned in the heat transfer tube. Each of the first flow paths includes a section with a rectangular shape that is elongated in a first direction parallel with an alignment direction of the first flow paths. Each of the first flow paths includes protrusions disposed on an inner surface. The section of each of the first flow paths has a long side having a first length and a short side having a second length, where a ratio of the first length to the second length is between 1.1 and 1.5.

摘要： A heat exchanger includes: heat transfer tubes aligned in an up-down direction; a liquid header connected to ends of the heat transfer tubes; and connection tubes aligned in the up-down direction and connected to the liquid header. The heat transfer tubes include: a first heat transfer tube disposed at a lowermost position; and a second heat transfer tube disposed above and adjacent to the first heat transfer tube. The connection tubes include: a first connection tube disposed at a lowermost position; and a second connection tube disposed above the first connection tube. The liquid header includes: a first flow path connected to the first connection tube and the first heat transfer tube; and a second flow path connected to the second connection tube and the second heat transfer tube.
