Title:
HEAT EXCHANGER AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/219719
Kind Code:
A1
Abstract:
Corrugated fins of this heat exchanger are structured so as to have plate-shaped fin portions connected in corrugated fashion in the axial direction of a plurality of flattened heat exchanger tubes. The fin portions are each equipped with: a drainage slit that is formed so as to extend in the direction in which the plurality of flattened heat exchanger tubes are aligned; and a plurality of louvers that have louver slits extending in the tube alignment direction and plate portions inclined with respect to a flat plate portion of the fin portion. The plurality of louvers are divided into a first louver group that is formed upstream of the drainage slit in the air circulation direction and a second louver group that is formed downstream of the drainage slit in the air circulation direction. The plate portions of the first louver group and the plate portions of the second louver group are inclined in mutually opposite directions with respect to the flat plate portion. The present invention has a plurality of rows of the drainage slits between the first louver group and the second louver group.
