FIELD: heating.
SUBSTANCE: invention relates to the field of heat engineering and can be used in the manufacture of heat exchangers. In the heat exchanger for use in an isothermal chemical reactor comprising several heat exchange plates, each of which includes the first and second metal sheets forming, respectively, the first side surface and the second side surface of the plate opposite to it, feeding the line of the coolant and the coolant collector, and several internal passages for the coolant between the first and second metal sheets, and the first and second sheets are joined by at least one welded joint formed on the first side surface, and the feeding the line of the coolant and the collector are formed by the feeding and collector channels and connected to the second metal sheet by the other welded joints performed on the said second plate surface.
EFFECT: providing the manufacture of the plate by the automated welding process, such as laser welding.
