Title:
HEAT EXCHANGER AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/219919
Kind Code:
A1
Abstract:
This heat exchanger comprises: a plurality of flat heat transfer tubes which are disposed upright in the vertical direction and provided in parallel at intervals in a direction orthogonal to an air circulation direction; and corrugated fins disposed between the plurality of flat heat transfer tubes. The corrugated fins of the heat exchanger have a configuration in which plate-shaped fin parts are continuous in wave shapes in a tube axis direction of the plurality of flat heat transfer tubes, and the fin parts include drainage slits that are formed extending in a tube parallel arrangement direction, which is the parallel arrangement direction of the plurality of flat heat transfer tubes, and cause water on the upper surfaces of the fin parts to drop off and drain, and a plurality of louvers having louver slits extending in the tube parallel arrangement direction and plate parts that are inclined with respect to a flat plate-shaped flat plate parts of the fin parts. The plurality of louvers are divided into a first louver group formed on an upstream side of the drainage slits in the air circulation direction, and a second louver group formed on the downstream side of the drainage slits in the air circulation direction. The plate parts of the first louver group and the plate parts of the second louver group are inclined in opposite directions to each other with respect to the flat plate parts. The drainage slits are formed in a plurality at intervals in the air circulation direction between the first louver group and the second louver group.
