<p>PURPOSE: To provide a heat exchanger for dehumidifying compressed air which can strengthen the degree of dryness of compressed air by cooling and dehumidifying the air beyond the capacity of a cooler installed without enlarging an apparatus and making constitution complex. CONSTITUTION: In a heat exchanger for dehumidifying compressed air in which in a pressure container 2 having an inlet and an outlet 3b, a cooler 16 is placed and baffle plates 17,... are installed to form an air cooling channel snaking from an inflow port 15a to an outflow port 15b, one baffle plate 17a near the outflow port of the air cooling channel is installed protrudingly toward the wall surface in the air channel to form a contraction port S which makes the area of a compressed air passing clearance narrower than those of other passing clearances. In this way, the temperature of compressed air is lowered by adiabatic expansion when the air passes through the contraction port to be cooled and dehumidified.</p> |
