Abstract
The fin for a heat exchanger which consists essentially of a matrix of tubes and of fins disposed transversely to the latter, the fin having pass-through elements to receive tubes which are to be joined mechanically, while a first, preferably liquid medium flows through the tubes and the fin is acted on by a second, preferably gaseous medium. Multiple fins are positioned in their fin pitch by integral spacers, wherein the spacers are in the form of noses stamped out of the pass-through elements and distributed over the periphery of the latter.
