FIELD: chemistry.
SUBSTANCE: proposed plate heat exchanger for heat exchange in a chemical reactor unit has box frame with a flat rectangular shape. The frame is in form of a rectangular parallelepiped with an inner cavity, joined to inlet and outlet connection pipes for fluid heat carrier. A distribution pipe is put inside the frame, passes along its longer length and consists of two - outer and inner - pipes, one put into the other. The space between them is linked through several openings made on the outer pipe, with the inner cavity of the heat exchanger and with the inner pipe. The inner pipe is joined to the inlet connection pipe of the heat exchanger, meant for inlet of fluid heat carrier. Movement of the inner pipe about the outer pipe is restricted by projections or restraining. Invented also is a method of making the plate heat exchanger and a chemical reactor with a heat exchange unit.
EFFECT: more efficient reaction and reduced input of fluid heat carrier.
