HEAT EXCHANGER, HEAT EXCHANGER UNIT, AND REFRIGERATION CYCLE DEVICE

Document Type and Number:

WIPO Patent Application WO/2019/239520

Kind Code:

A1

Abstract:

The purpose of the present invention is to obtain a heat exchanger, a heat exchanger unit, and a refrigeration cycle device in which heat exchange performance, drainage performance, and resistance to frost formation are improved. This heat exchanger is provided with a flat pipe and a plurality of fins formed from a plate-shaped body having a plate surface that extends in a lengthwise direction and in a width direction orthogonal to the lengthwise direction, said fins being arranged at intervals and such that the plate surfaces thereof intersect the pipe axis of the flat pipe. Each of the plurality of fins is provided with a first interval-maintaining section that is formed on the plate-shaped body and that is for maintaining the intervals. The flat pipe is arranged so that the major axis of a cross section perpendicular to the pipe axis is inclined at an inclination angle θ with respect to the width direction. The first interval-maintaining sections comprise a rising surface extending in a direction that intersects the plate surfaces, and the rising surfaces are inclined in the same direction as the inclination angle θ.
