<p>PURPOSE:To provide cold air drier making it possible to make components constituting a cooler and a reheater respectively in common, improve assembling properties and improve the efficiency of heat exchange. CONSTITUTION:A cold air drier is equipped with a cooler 20 and a reheater 22. A high-temperature refrigerant discharged from a compressor is condensed by a condenser, the pressure is reduced thereby and it is made to flow into the cooler 20 and to fulfill a cooling function, while it is made to flow into the reheater 22 and to fulfill a heating function. The cooler 20 and the reheater 22 are constituted of heat exchangers having a plurality of radiating fins Fa and Fb pierced by meandering refrigerant pipings Ca and Cb respectively, while the number of lines and stages of both of the refrigerant pipings Ca and Cb is made the same and the radiating fins Fa and Fb are disposed at different pitches from each other.</p> |
