摘要

The fin has flanks provided between flat wave crests (2) and/or flat wave troughs (3), and arranged between flat pipes in a heat exchanger. Recesses (10) are provided at a distance in the wave crests and the wave troughs. Caved-in sections (11) are formed inwards between two recesses. The sections are displaceably arranged at each wave crest and wave trough. The flanks have exposed cuts, which extend over the entire height of the fin.
