A plate heat exchanger has flow channels through which a first and a second flow passes in concurrent or countercurrent flow. The flow channels are formed for the first medium between individual plates (1) joined together to form in each case a pair (P) of plates, and for the second medium between pairs (P) of plates joined together to form a stack (S) of plates, wherein the individual plates (1) within an inlet region (E) have guide blades (2) which are formed by stamped embossments and protrude into the flow channel, wherein the guide blades (2) are formed in an arch-shaped manner with an inflow leg (21) aligned substantially parallel to the main flow direction and an outflow leg (22) aligned at an angle to the inflow leg (21).
