FIELD: heat-exchange apparatus.
SUBSTANCE: plate heat exchanger comprises the frame with a stack of U-shaped aluminum plates with flanged edges of 0.13-03 mm in thick and spaced at a distance of 3-5 mm and spacing inserts with passages for fluids. A space is defined between the flanged edges of the mating plated. The space is filled with a high-temperature sealing compound. The frame is compressed by means of an angle in the corner of the stack of aluminum plates with spacing inserts made of stiffening ribs.
EFFECT: enhanced reliability and simplified structure.
