Abstract
The invention involves a countercurrent heat exchanger for condensation laundry dryers of the type that is the object of DE 198 38 525 A1. In order to increase the cooling output of the heat exchanger plates (12) stacked into a heat exchanger plate stack (10), which each contain at least one humid air channel (14) and are made out of thermoplastic plastic or from a film consisting of a heat-conducting metal, the heat exchanger plates (12) are equipped with several struts (32) that form cooling lamellas which project outward from them and extend perpendicularly to the humid air channel (14), and which form pockets that open into the humid air channel (14).
