Date Dec. 12, 1996Plate heat exchanger (1) comprising a plurality of rectangular plate elements (2) and intermediary gaskets (3) held clamped in a stack (4). At least two diagonally opposed corners (7) of each plate (2) in the stack (4), comprise depressed corner areas, which are connected to the inner plate area at a concave bending line (9). The outer contour of the depressed corner area of a plate (2) in the stack (4) is in positive engagement with the inner contour of the depressed corner area of the next following plate (2) in the stack (4). This ensures alignment of the stack, both during assembly and during subsequent use.
