Title:
HEAT EXCHANGER, HEAT EXCHANGER UNIT, AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/012577
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a heat exchanger, a heat exchanger unit, and a refrigeration cycle device in which melted water from frost is prevented from reaching the upper surface of a header and in which heat exchange performance and reliability are improved. The present invention comprises a plurality of heat transfer pipes disposed in parallel, a fin connected to at least one heat transfer pipe from among the plurality of heat transfer pipes, and a header that is connected to one end part of the plurality of heat transfer pipes and has a header end surface that extends along a direction parallel to the plurality of heat transfer pipes. The fin has a first portion including a header-side end edge and a second portion that excludes the first portion, and extends along a first direction that intersects the direction in which the plurality of heat transfer pipes are disposed in parallel, said first direction being orthogonal to pipe axes of the plurality of heat transfer pipes. A first-direction leading end part of the first portion is positioned so as to protrude farther in the first direction than the header end surface, and a first-direction leading end part of the second portion is positioned closer to the plurality of heat transfer pipes in the first direction than the header end surface.
