Heat exchanger of the crosscurrent type

A heat exchanger of the crosscurrent type, through which at least two fluids flow, comprising;

• a plurality of pairs of plates that are stacked one on the other between two cover plates, the plates of each pair being spaced from one another in a first region and being in contact in a second region, so that fluid paths are formed between them in a heat transfer region;
• each pair of plates including inlet ducts and outlet ducts arranged laterally in duct regions and formed from inlet duct openings and outlet duct openings in the plates,
• at least one inlet duct and one outlet duct in a first pair of plates being fluidically connected to a group of fluid paths formed between a third pair of plates separated from the first pair of plates by a second pair of plates;
• wherein the spacing of the plates in each pair is achieved by means of shaped-out portions of the plates;
• and
• further comprising deep-drawn turbulators integrated into the plates, wherein the turbulators are in the form of winglets.

• and
• wherein the plates of the first and third pairs are spaced farther apart than the plates of the intermediate second pair in order to receive corrugated fins.
