Abstract (en)
Finned heat exchanger having tubes (4) which are arranged in at least one row and through which a fluid to be heated flows, and which are penetrated by the fins (3), which are arranged parallel to one another. In order to avoid the formation of dead spaces due to the formation of drops of condensate, it is provided that there are provided in the region of the rim of the fins (3) that lies downstream of the flue gas current, impressions (8) which are open towards said rim and are arranged between the rows of tubes (4) nearest said rim of the fins (3). <IMAGE>

Lamellenwärmetauscher mit in mindestens einer Reihe angeordneten, von einem aufzuheizenden Fluid durchströmten Rohren (4), die die parallel zueinander angeordneten Lamellen (3) durchsetzen. Um die Ausbildung von toten Räumen durch Kondensattropfen zu vermeiden, ist vorgesehen, daß im Bereich des stromab des Rauchgasstromes gelegenen Randes der Lamellen (3) zu diesem hin offene Einprägungen (8) vorgesehen sind, die zwischen den in der diesem Rand der Lamellen (3) nächsten Reihe von Rohren (4) angeordnet sind. <IMAGE>
