Title:
HEAT EXCHANGER AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/185840
Kind Code:
A1
Abstract:
This heat exchanger is provided with: a first fin; a second fin; a first heat transfer tube penetrating the first fin by being separated from an upstream end section of the first fin by a first specified distance; and a second heat transfer tube penetrating the second fin by being separated from an upstream end section of the second fin by a second specified distance. When the first heat transfer tube and the second heat transfer tube are observed such that the lower surface of the first heat transfer tube is horizontal, in a longitudinal plane perpendicular to the direction in which the first heat transfer tube penetrates the first fin, the upper surfaces of the first and second heat transfer tubes are inclined downward toward the upstream end sections of the first and second fins, an upper end of the second heat transfer tube is positioned above the lower surface of the first heat transfer tube, and an intersection point A, which is a point where an extension line of the upper surface of the second heat transfer tube, and an extension line of the lower surface of the first heat transfer tube intersect each other, is positioned further toward the second heat transfer tube side than an intersection point B, which is a point where the extension line of the upper surface of the second heat transfer tube and an extension line of the lower surface of the second heat transfer tube intersect each other.
