Abstract (de)

In einem Haushaltwäschetrockner nach dem Kondensationsprinzip mit einem Plattenwärmetauscher 1 kann der zu kühlende Gasstrom S am Einlaß und/oder am Auslaß des Wärmetauschers 1 schräg zur Ebene der Wärmetauschplatten 2 verlaufen. Die dadurch auftretenden Strömungswiderstände können erfindungsgemäß verringert werden, indem vom Gasstrom S umströmte Enden der Wärmetauschplatten 2 insbesondere am Einlaß des Wärmetauschers 1 treppenförmig versetzt angeordnet sind. Auf diese Weise kann auch die Verteilung des Gastroms S auf die einzelnen Wärmetauschplatten 2 entsprechend deren Wärmetauschleistung optimiert und damit der erzielte Wärmeaustausch verbessert werden. In einer vorteilhaften Weiterbildung können vom Gasstrom angeströmte Enden der Wärmetauschplatten 2 Gasumlenkungsteile 4 aufweisen, die im wesentlichen dem Gasstrom S folgen und die Strömungsverluste weiter verringern <IMAGE>
