The invention relates to a turbulence-generating insert (100) for a flow channel of a heat exchanger. The insert has rib corrugations (120) having ribs (160) which are arranged in an arrangement direction (130) and are positioned at a predetermined offset (180) from each other in a corrugation direction (110), and the peaks (140) and/or valleys (150) of the rib corrugations (120) have flattened top regions (170). Such a turbulence-generating insert (100) can be produced in an efficient and cost-effective manner by means of a modification method using profile rolling if the flattened top region(170) has a first inclined position (210) extending at a predetermined first angle (beta) relative to the corrugation direction (110). 本发明涉及一种产生湍流的置入件(100)，用于换热器的流动通道。该置入件具有肋型波纹(120)，这些肋型波纹具有沿排列方向(130)布置的并且沿波纹方向(110)相互间以预定的偏移量(180)定位的肋(160)，其中，肋型波纹(120)的波峰(140)和/或波谷(150)具有被弄平的顶部区域(170)。如果被弄平的顶部区域(170)具有相对于波纹方向(110)以预定的第一角度(β)延伸的第一倾斜姿态(210)，那么这种产生湍流的置入件(100)就可以借助利用型材轧制的改型方法来高效且节省成本地制造。
