The fins may have flanks running transversely to the transverse direction from an upper side of the respective corrugated fin to an underside of the respective corrugated fin, and which may be interconnected via connecting sections. A fin division of the respective corrugated fin, which may correspond to a period length of the respective corrugated fin, may be smaller than twice a fin width, which may correspond to a width of one of the connecting sections. The connecting sections may have exterior bearing surfaces, which may serve as adhesive surfaces, to which adhesive may be applied to adhere the at least two corrugated fins.
