The invention refers to a heat exchanger plate ( 4 ) for a plate heat exchanger ( 1 ), a plate package ( 3 ) and a plate exchanger ( 1 ). The plate ( 4 ) includes at least a first area ( 31 ) with a corrugation of ridges and valleys, the plurality of which extends in a first direction (A), and at least a second area ( 32 ) with a corrugation of ridges and valleys, the plurality of which extends in a second direction (B). The plate ( 4 ) has a central rotary axis extending in parallel with a normal line of the plate. The areas ( 31, 32 ) have a respective contour coinciding with a respective imaginary contour in a first rotary position of the plate with regard to the rotary axis and after a rotation 90° to a second rotary position of the plate with regard to the rotary axis. |
