ABSTRACT:
A humid compressed-gas dryer includes a plate-type heat-exchanger that includes a plurality of stacked plates (2) associated with each other in a gas-tight manner all along the perimeter of adjacent plates (2). The adjacent plates (2) define channels (3) therebetween for two or more fluids to be guided therethrough in a heat-exchange relation. The plates and have a plurality of apertures (4, 15-21) disposed in a mutually aligned arrangement, which defines fluid conduits that extend through the heat-exchanger in fluid communication with the channels (3). The plates (2) are each formed of an aluminium sheet having a smooth surface, and a corrugated aluminium fin (5) is provided between adjacent sheets defining the channels. The fin (5) has corrugations connected to the smooth surface of the plates by brazing or a similar method. The plurality of stacked plates defines a heat recovery section (12) and a cooling section (13).
