Document Type and Number:
WIPO Patent Application WO/2021/205738
Kind Code:
A1
Abstract:
A heat exchanger (4) comprises a front-surface heat exchanger (5) and a back-surface heat exchanger (6). Each of the front-surface heat exchanger (5) and the back-surface heat exchanger (6) has a plurality of heat transfer tubes (8), the plurality of heat transfer tubes (8) being arranged along a step direction and a row direction. In each of the front-surface heat exchanger (5) and the back-surface heat exchanger (6), the plurality of heat transfer tubes (8) are positioned so that line segments connecting the centers of heat transfer tubes (8) in the same step with a straight line in the row direction are substantially parallel to each other.
