FIELD: power engineering.
SUBSTANCE: invention relates to heat engineering and can be used in plate-type heat exchangers. Claimed heat exchanger comprises the flow channels for the first and second flows to flow in parallel or opposition. Note here that flow channels are formed for the first medium between separate plates (1) interconnected for formation of the pair of plates (P) and, for the second medium, between pairs of plates (P) interconnected to make the stack of plates (S). Separate plates (1) comprise within the inlet area (E the guide vanes (2) composed by moulded bulges to extend in the flow channel. Note also that said guide vanes (2) feature arched shape with inflow section (21) levelled, in fact, parallel with the main flow direction and outflow section (22) levelled at the angle to inflow section (21).
EFFECT: perfected design.
