摘要： To provide a heat exchange unit capable of suppressing an increase in manufacturing cost by preventing damage to a flat tube caused by sliding against other members. A utilization unit (3) includes a utilization heat exchanger (32) and a first member (34). In the utilization heat exchanger (32), a plurality of flat tubes (32a) are stacked at predetermined intervals in a thickness direction by a heat transfer fin (32b). The first member (34) is attached to the utilization heat exchanger (32). The first member (34) includes a body (34a) and a protrusion portion (34b) protruding from the body (34a). The protrusion portion (34b) is inserted between flat tubes (32a) adjacent to each other.

摘要： Water drainage between louvers is improved. Fins (50) have a plate-shaped part (60) positioned so that a plate-thickness direction intersects an air-flow direction (F), and have a plurality of louvers (61) protruding from the plate-shaped part (60) in the plate-thickness direction. Flat heat-transfer tubes (41, 42, 43...) are inserted into the fins (50) so as to intersect the air-flow direction (F). In particular, the louvers (61) have a first louver (62) and a second louver (63) that have different inclination angles with respect to the plate-shaped part (60). These louvers (62, 63) are positioned in alternation.

摘要： When a heating operation is performed at a low outdoor temperature, a heat exchanger of related art does not include a connection portion of heat transfer fins on a windward side or a leeward side, and hence there is a problem that dew condensation water cannot be properly drained and frosting is likely to occur. An outdoor heat exchanger (24) includes a plurality of flat tubes (243), a plurality of first heat transfer fins (241), and a plurality of second heat transfer fins (242). The plurality of first heat transfer fins (241) are inserted with respect to the plurality of flat tubes (243) from a windward side in an air flow direction of sections of the flat tubes (243). The plurality of second heat transfer fins (242) are inserted with respect to the plurality of flat tubes (243) from a leeward side in the air flow direction of the sections of the flat tubes (243). A first connection portion (241b) of the first heat transfer fin (241) connects a plurality of first insertion portions (241a). A second connection portion (242b) of the second heat transfer fin (242) connects a plurality of second insertion portions (242a).
