The invention relates to a fin for a heat exchanger, comprising a fin element which extends in the flow direction of a first fluid and has a wall face around which the first fluid flows on both sides, wherein at least one flap is provided in the wall face, which flap forms a cutout, through which the first fluid can flow, in the wall face, wherein a first edge of the flap for forming the cutout is arranged spaced apart from the wall face, wherein the flap has a tab face which is inclined with respect to the wall face and terminates at the first edge, wherein the tab face is connected to the wall face via at least one side wall, extending with a curved profile, of the flap, which side wall, starting at the first edge, has a height which decreases in a way which corresponds to the inclination of the tab face.

The invention relates to a process for producing a turbulence apparatus and to an apparatus for producing the turbulence apparatus which is to be held in at least one flow duct of a heat exchanger of a motor vehicle, comprising the following process steps: in a first process step, at least one shaping operation is used to produce at least one substantially meandering turbulence apparatus (30) with substantially smooth walls (2) from a substantially continuously planar sheet-metal strip (9), wherein a longitudinal direction (LR) of the walls (2) runs substantially parallel to a forward feed direction (VR) of the sheet-metal strip (9). In a second process step, wall sections are deformed at least by an angle (a) with respect to the forward feed direction (VSR) in such a way that undercuts (3) are produced with respect to the forward feed direction (VSR), wherein the substantially continuous sheet-metal strip (9) is cut to length into turbulence apparatuses (1, 30) of predetermined lengths before the second process step is carried out.
