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.

Claim (Index 17):
The heat exchanger according to  claim 16 , wherein\n the header has a loop structure including:\n an inflow port through which the refrigerant is caused to flow into a first space on the first side when the heat exchanger functions as a refrigerant evaporator; \n a first communication passage via which a portion of the first space toward a first end in a longitudinal direction of the header and a portion of a second space toward the first end in the longitudinal direction of the header communicate with each other, and through which the refrigerant that has flowed inside the first space is guided to the second space on a side opposite to the first side; and \n a second communication passage through which the refrigerant that has flowed in the second space is returned to a second end of the first space opposite to the first end in the longitudinal direction of the header, and \n at least a portion of the first space between the first communication passage and the second communication passage is formed so as to cause a larger amount of refrigerant to flow on the upstream side than on the downstream side in the direction of the airflow.
