Abstract (en)
[origin: US5299633A] A heat exchanger device for refrigeration driers in compressed-air installations is described. Such heat exchanger devices have an air/air heat exchanger (1) and a refrigerant/air heat exchanger (2). According to the invention, the air/air heat exchanger is produced as a plate heat exchanger and the refrigerant/air heat exchanger is produced as a combined tube/plate heat exchanger. The tube/plate heat exchanger has at least one unit containing a tube coil being coiled in a meandering manner and forming two spaced broad sides, and two plates, each plate being fastened at one of the two broad sides (FIG. 1 ).
