The invention relates to a turbulence insert (21) for flat tubes (4) for heat exchangers, said turbulence insert (21) being embodied as a single-layered strip (22) of sheet metal and comprising first and second projections (30, 31) that are formed in the strip (22) of sheet metal, the first projections (30) being arranged on a first side of the central plane (26) of the strip and the second projections (31) being arranged on a second side of the central plane (26) of the strip, opposite the first side. The first and second projections (30, 31) are arranged respectively successively and alternately, in the longitudinal direction (24) of the strip, in the form of a longitudinal row (35). The turbulence insert (21) comprises at least two longitudinal rows (35) that are adjacent in the direction of the width of the strip. |
