Abstract

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>
