摘要： There are provided a heat exchanger and an air conditioner capable of minimizing a difference in state between a refrigerant that flows on the windward side and a refrigerant that flows on the leeward side in flat multi-hole tubes even when a difference in pressure-resistance strength between the windward side and the leeward side of the flat multi-hole tubes is minimized. An outdoor heat exchanger (20) includes a plurality of flat multi-hole tubes (50), a return header (24), a plurality of heat transfer fins (40), and a partitioning member (70) including a concave-convex portion (88a) on the leeward side. A space (61a, 61b) inside the return header (24) to which the flat multi-hole tubes (50) are connected is formed so as to cause a larger amount of a refrigerant to flow on the upstream side than on the downstream side in an airflow direction.

The inner board (63) has a surface (631) facing the surface (622). The outer board (61) has a surface (614). The surface (614) crosses the surface (622) and the surface (631), and is bonded to the inner board (62) and the inner board (63). The surface (622) and the surface (631) are bonded by a brazing material having a first thickness. The surface (614) and the inner board (62) are bonded by a brazing material having a second thickness. The surface (614) and the inner board (63) are bonded by a brazing material having a third thickness. The first thickness is less than the second thickness.
