Document Type and Number:
WIPO Patent Application WO/2016/194088
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve discharge performance related to water generated during a defrost operation, in a heat exchanger. The present invention is provided with: plate-like fins (2); a first flat tube (3) intersecting the plate-like fins; and a second flat tube (30) which intersects the plate-like fins, and which is disposed at an interval from the first flat tube and facing a lower surface portion (3c) of the first flat tube. A side surface portion (3b) of the first flat tube at the upstream side of the airflow and a side surface portion (3b) of the second flat tube at the upstream side of the airflow are positioned further inside than peripheral edges of the plate-like fins. The plate-like fins each have a cut-and-raised piece (23) provided in a position between the first flat tube and the second flat tube. The cut-and-raised pieces are positioned between a first virtual plane (32) joining the side surface portion of the first flat tube at the upstream side of the airflow and the side surface portion of the second flat tube at the upstream side of the airflow, and a second virtual plane (34) joining the centre of the lower surface portion of the first flat tube and the centre of an upper surface portion (3a) of the second flat tube.
