Title:
HEAT EXCHANGER, HEAT EXCHANGER UNIT, AND REFRIGERATION CYCLE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/239519
Kind Code:
A1
Abstract:
The purpose of the present invention is to obtain a heat exchanger, a heat exchanger unit, and a refrigeration cycle apparatus, wherein deterioration in water drainage performance and air ventilation performance is suppressed, blockage of an air channel is unlikely to occur when frost formation occurs, and both defrosting performance and heat exchange performance are achieved. The present invention is provided with: a flat pipe; and a plurality of fins formed of plate-shaped bodies having plate surfaces extending in a longitudinal direction and a width direction perpendicular to the longitudinal direction, the fins being disposed to cross a pipe axis of the flat pipe and arranged spaced apart from each other. Each of the plurality of fins is provided with: an insertion part into which the flat pipe is inserted; a first spacing part that is formed on a peripheral edge of the insertion part and maintains spacing; and a second spacing part that is formed on the plate-shaped body except for on the peripheral edge of the insertion part and maintains spacing. The first spacing part is located, at the peripheral edge of the insertion part, on one end portion side in the longitudinal direction of a cross-section perpendicular to the pipe axis of the flat pipe.
