Abstract: A plate heat exchanger comprises a heat exchanger plate having a quadrilateral shape with two opposite primary sides and two opposite secondary sides, and a longitudinal central axis being parallel with the primary sides. The heat exchanger plate comprises a heat exchanger area having a corrugation of ridges and valleys. Four porthole areas are located at a respective corner of the heat exchanger plate and each comprises a respective porthole extending through the heat exchanger plate. An edge area extends around and adjoins the heat exchanger area and the porthole areas. The heat exchanger area comprises a main area and a local part area extending along one of the primary sides and adjoining the edge area and one of the porthole areas. The valleys of the local part area are tapering towards the longitudinal central axis.
