HEAT EXCHANGER AND METHOD FOR DRYING A HUMID MEDIUM

摘要

The invention relates to a heat exchanger and a method for drying a humid medium. In the heat exchanger there is arranged an internal cross-over passage (5), allowing the humid medium to double back on itself in a zone (1) delimited by a barrier (3), in a first step cooling itself and in a final step heating itself. The invention also features separation areas (10) allowing condensation and collection of water within the heat exchanger. The invention enables drying of compressed air within one and the same heat exchanger package.
