Abstract

The present application provides a heat exchange fin and a heat exchange device. The heat exchange fin comprises a plurality of water pipe through holes arranged side by side perpendicular to a flue gas flow direction, wherein a notch and a flanging hole are sequentially formed between the adjacent water pipe through holes along the flue gas flow direction, an edge of the notch is provided with a first flue gas baffle, and a first opening is formed at the center of the first flue gas baffle. In the present application, the temperature distribution of the heat exchange fin is more uniform, possibility of generation of the condensed water is reduced on the premise of ensuring heat exchange efficiency, thereby prolonging the service life of the heat exchange.
