ABSTRACT:
The invention refers to a heat exchanger plate (4) for a plate heat exchanger, a plate package, and a plate heat exchanger. The plate includes an edge, which extends around the plate, an edge area (6) which extends around the plate inside the edge, and a heat exchanging surface (5) with a corrugation of ridges and valleys which extend in at least a first direction (A, B) over the plate (4). Furthermore, the plate includes a support area (41), which extends around the heat exchanging surface (5) inside the edge area (6) and includes a corrugation of ridges (42) and valleys (43).
