Title:
FIN TUBE HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2022/044523
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce pressure loss in heat exchange air while maintaining heat exchange performance. This fin tube heat exchanger (1) comprises a tube row (22) in which a plurality of heat transfer tubes are positioned side-by-side at a prescribed pitch (P1) in a first direction intersecting the direction in which heat exchange air is channeled. A plurality of tube rows are positioned at prescribed intervals (P2) in a second direction intersecting the first direction. A prescribed tube row is positioned so as to be offset in the first direction relative to another tube row adjacent in the second direction. When viewed in the direction in which the heat exchange air is channeled, the heat transfer tubes of a prescribed tube row are positioned so as to be biased towards the heat transfer tubes of another adjacent tube row.
