Abstract

A process for producing a turbulence device (1) which is to be mounted in at least one flow duct of a heat exchanger of a motor vehicle includes the steps of, in a first process step, at least one shaping operation is used to produce at least one substantially meandering turbulence device (30) with substantially smooth walls (2) from a substantially continuously planar sheared strip (9), wherein a longitudinal direction (RLR) of the walls runs substantially parallel to a forward feed direction (VSR) of the sheared strip (9), and in a second process step, wall sections are deformed at least by an angle (α) in relation to the forward feed direction (VSR), in such a way that undercuts (3) are produced in relation to the forward feed direction (VSR, RLR), wherein the substantially continuously planar sheared strip (9) is cut into turbulence devices (1) of predetermined lengths before carrying out the second process step.
