Document Type and Number:
WIPO Patent Application WO/2022/049886
Kind Code:
A1
Abstract:
Provided is a corrugated fin-type heat exchanger that can improve heat exchange performance and energy consumption efficiency even under conditions of use in which wind speed is relatively slow. This corrugated fin-type heat exchanger comprises a pair of header pipes, a plurality of heat exchange tubes connected to the header pipes and parallel to each other, and a corrugated fin 4 joined between the heat exchange tubes, wherein the corrugated fin 4 includes a plurality of louvers 10 (10a, 10b) that are cut and raised in an air flow direction perpendicular to the longitudinal direction of the heat exchange tube.
