FIELD: process engineering.
SUBSTANCE: invention relates to heating engineering and may be used for making of heat exchanger plates. Heat exchanger plate (106) has first surface parts (210) located along first plate edges (220) and including first contact areas (214) and second surface parts (212) located along second plate edges (222). First surface parts (210) are bent towards first side to get first incomplete fluid channel (230) while second surface parts (212) are bent toward second side to get second incomplete fluid channel (232). First contact area (214) define the plane (S). Heat exchanger plate (106) has angular surface parts (224) with angular parts (226) of first edge and angular parts (228) of second edge. At least two angular surface parts (224) are bent inward relative to said incomplete fluid channel (230) so that their angular parts (226) of first edge are located in said plane (S) while their angular parts (228) of second edge are perpendicular to said plane (S).
EFFECT: decreased inlet turbulence.
