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 11):
A heat exchanger comprising:\n a plurality of flat multi-hole tubes that are disposed in line such that a direction intersecting a direction of an airflow is a longitudinal direction of each of the plurality of flat multi-hole tubes; a header to which an end portion of each of the plurality of flat multi-hole tubes is connected; and a plurality of fins that are joined to the plurality of flat multi-hole tubes, wherein a space formed inside the header-causes a larger amount of refrigerant to flow on an upstream side than on a downstream side in the direction of the airflow, a concave-convex portion is provided on a part of a contour of the space that faces the end portion of each of the plurality of flat multi-hole tubes on the downstream side in the direction of the airflow, the concave-convex portion includes a convex portion that projects toward the plurality of flat multi-hole tubes and a concave portion that is oppositely recessed, and the convex portion and the concave portion extend in a longitudinal direction of the header respectively.
