Abstract
The present invention relates to a fin device for heat exchangers having corrugated fins, which extend along a main direction and comprise fin walls with louvres and fin folds. With respect to the corrugated fins, fin walls that are adjacent in the main direction are each interconnected via a fin fold, while in addition, fin walls that are adjacent in the main direction each delimit between them a fluid channel. Furthermore, the corrugated fins are lined up one behind the other in a transverse direction extending transversely to the main direction, so that the fluid channels () of the corrugated fins lead into one another. It is substantial that corrugated fins that are adjacent in the transverse direction are arranged offset to one another in the main direction by a spacing referred to as fin offset and are fixed to one another in that their adjacent fin folds are directly and in particular integrally connected to one another. The present invention, furthermore, relates to a heat exchanger having fin devices and to a method for manufacturing such a fin device.
