<p>A heat exchanger may include a plurality of layers arranged on top of each other, each of the layers having a first cavity for the passage of a medium and a second cavity for the passage of a coolant. Each layer may define a through hole for the passage of the medium and each layer may include a frame in which a turbulence insert may be inserted. Each frame may have an end region configured to define at least one channel closure and the through holds for the passage of the medium. The frame may have a guide opening for receiving an assembly aid and the guide opening may be formed between the through holes and the channel closure.</p> |
