Abstract
An outdoor heat exchanger includes a plurality of flat multi-hole tubes, a return header, a plurality of heat transfer fins, and a partition including a concave-convex portion on the leeward side. A space inside the return header to which the flat multi-hole tubes are connected is formed so as to cause a larger amount of refrigerant to flow on the upstream side than on the downstream side in an airflow direction.
