Japanese Patent JP7223991
Kind Code:
B2
Abstract:
To improve dew condensation water discharge performance of a heat exchanger.SOLUTION: In a heat exchanger, each fin section of a plurality of corrugated fins has a plurality of blade sections so as to form a plurality of window sections. The plurality of corrugated fins is installed so that a longitudinal direction of installation sections to which a heat exchange tube is installed is perpendicular to a flow direction of a second heat exchange medium flowing in the heat exchange tube. When operated in a position with the longitudinal direction of the installation sections of the corrugated fins arranged vertically, the heat exchanger allows dew condensation water generated on the corrugated fins through heat exchange to be discharged in a manner that flows down along the installation sections, thereby improving dew condensation water discharge performance of the heat exchanger.SELECTED DRAWING: Figure 1
