Abstract (en)
[origin: US2010218922A1] 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.
