Abstract

The invention relates to a plate-fin heat exchanger with light weight, low cost, big available space and higher heat exchanging efficiency, comprising shell, pre-cooling segment and evaporation segment set in the shell. Said pre-cooling segment and evaporation segment comprise channel structure for cool resource and channel structure for hot air respectively. The channel structure for hot air of pre-cooling segment is connected with the channel structure for hot air of evaporation segment. The channel structure for cool resource of pre-cooling segment is parted with the channel structure for cool resource of evaporation segment by clipboard. Air inlet is set on the shell above said pre-cooling segment and water drainage structure is set on the shell under said evaporation segment. It is characterized in that said pre-cooling segment and evaporation segment, as a integrity, is set in the side upper of internal space of said shell; the bottom and a side in the internal space of said shell are hollow; the air in said evaporation segment comes out from the bottom of fin and enters into pre-cooling segment from one side of pre-cooling segment along the hollow part and the outlet for drying air is connected with said shell relative to the other side of said pre-cooling segment.
