PURPOSE: A plate heat exchanger is provided to minimize the flow of a thermal medium without the interaction through individual plates and increase thermal flow rates for a predetermined size of plate. CONSTITUTION: A plate heat exchanger has flow channels through which a first flow and a second flow pass in concurrent or countercurrent flow. The flow channels are formed for the first medium between individual plates (1) joined together to form a pair of plates in each case and for the second medium between the pairs of plates joined together to form a stack (S) of plates. The individual plates within an inlet region (E) include guide blades (2) which are formed with stamped embossments and protrude into the flow channel. The guide blades are formed in an arch-shaped manner with an inflow leg (21) to be parallel to the main flow direction and an outflow leg (22) aligned at a predetermined angle to the inflow leg. |
