FIELD: heating equipment.
SUBSTANCE: invention relates to heat engineering and can be used in plate heat exchangers. Heat exchange plate (1) comprising edge (2), groove (3) made along edge (2), and corrugated area (4) having protrusions (5) and recesses (6) between groove (3) and edge (2), wherein protrusions (5) are made substantially perpendicular to edge (2), and groove (3) comprises outer wall (7) adjacent to corrugated area (4), and inner wall (8), wherein outer wall (7) has a wavy mold.
EFFECT: higher reliability of a heat exchanger with simplified design.
