摘要： A heat exchanger (5) comprises a plurality of flattened heat exchanger tubes (11) and a hollow header (12). The header (12) has: an inlet plate (120) that divides the interior of the header (12) into an inlet section (12F) where a refrigerant flows in and a circulation section (12S) that is located above the inlet section (12F); and a first partition member (121) that divides the circulation section (12S) into an ascending path (12Su) located inside,to which the ends of the plurality of flattened heat exchanger tubes (11) are connected, and a descending path (12Sd) located outside, and forms an upper communication path (12St) that is located on the upper side of the circulation section (12S) and allows communication between the ascending path (12Su) and the descending path (12Sd) and a lower communication path (12Sb) that is located on the lower side of the circulation section (12S) and allows communication between the ascending path (12Su) and the descending path (12Sd). The inlet plate (120) has, on the leeward side on the ascending path (12Su)-side, a first jet hole (121H1) for jetting the refrigerant from the inlet section (12F) into the ascending path (12Su).

摘要： A heat exchanger (23) comprises: a first row heat exchange module (50a) into which a refrigerant flows from the outside; a second row heat exchange module (50b) through which the refrigerant flows out to the outside; a third row heat exchange module (50c) through which the refrigerant flows out to the outside; and a split-flow module (40) which splits the refrigerant from the first row heat exchange module (50a) into the second row heat exchange module (50b) and the third row heat exchange module (50c). The first row heat exchange module (50a) forms a refrigerant outward path (50aD), and each of the second row heat exchange module (50b) and the third row heat exchange module (50c) forms a refrigerant return path (50bU, 50cU). This results in a single round trip refrigerant flow path.
