FIELD: heating.
SUBSTANCE: plate (2) of a plate-type heat exchanger with basic heat exchange section (14) comprises the first area (16) including the first field (30) with the first corrugations which is essentially set on one side of the straight first line (26) crossing the second side edges (6a, 6b) and the second field (32) with the second corrugations which is essentially set on the opposite side to the first line (26). The basic heat exchange section (14) comprises the first outer area (18) set aside the first area (16) and passing along the second side edge (6a) between two distribution sections (12a, 12b). The first outer area (18) includes first ridges and recesses oriented in the first common direction in relation to the straight second line (27) parallel to one of the first side edges (4a, 4b).
EFFECT: increased efficiency of sheet material usage and simplified manufacturing of heat exchanger plates.
