A plate heat exchanger comprises heat exchanger plates (5) each with a heat exchanger surface (4) having a sinuous profile, the plates being assembled with neighbouring plates being turned through 180 DEG about an axis perpendicular to the flow direction. An uneven number, which is greater than one, of segments (1a, 1b, 1c) is arranged transversely to the flow direction over the width of the heat exchanger surface (4) and the width of the segments arranged at both sides of the plate is different. The angles ( alpha a, ???b), which the sinuous profile elements (3) of the individual segments form with the flow direction are substantially equal in the case of the mutually opposite segments of adjacent plates in the exchanger. <IMAGE> |
