A plate-type heat exchanger for oil/coolant coolers on heat exchange media, as a rule, flow non-uniformly through known plate-type heat exchanger whose hollow chambers are provided with metal turbulence inserts because of the arrangement of these turbulence inserts. For increasing the heat exchange capacity, it is provided to divide the turbulence insert into sections in which a different alignment of rolled metal turbulence sheets takes place in each case. The sections are divided with respect to one another by separating cuts and, because of the different arrangement of their corrugations, have different flow resistances in sections for the flowing-through medium. As a result of this further development, it is possible to achieve a uniform flow in the hollow chambers.
