Document Type and Number:
WIPO Patent Application WO/2017/183180
Kind Code:
A1
Abstract:
This heat exchanger comprises: a plurality of flat pipes (11) provided so as to extend along a first direction; and a plurality of plate-shaped fins (12), each having a surface (12S) extending along a second direction (B) differing from the first direction. The plurality of plate-shaped fins (12) is arranged such that the surfaces (12S) are spaced apart from one another in the first direction. Each surface (12S) has an upwind side edge part (12A) positioned at the upwind side in the second direction and a downwind side edge part (12B) positioned at the downwind side in the second direction. Each of the plurality of flat pipes (11) penetrates the surfaces (12S). The plurality of flat pipes (11) includes: a first flat pipe (13) positioned furthest to the upwind side in the second direction (B); and a second flat pipe (14) arranged spaced apart from the first flat pipe (13) in the second direction (B) and positioned furthest to the downwind side. In the second direction (B), the distance (u) between the downwind side edge part (12B) of each surface (12S) and the flat-shaped center (14C) of the second flat pipe (14) is one-third or more the width (L) between the upwind side edge part (12A) and the downwind side edge part (12B) of the surface (12S).
