FIELD: heat-power engineering; plate-type and tubular recuperative heat exchangers.
SUBSTANCE: proposed heat-exchange surface is corrugated according to first version; ratio of pitch of corrugation to their height is equal to 4.0-12.0; height of corrugations does not exceed two thicknesses of heat-exchange surface (at its thickness not exceeding 0.5 mm); corrugations are made in one or in two mutually perpendicular directions. According to second versions, heat-exchange surface is corrugated and ratio of corrugations to their height is equal to 4.0-12.0; height of corrugations does not exceed two thicknesses of heat-exchange surface (at its thickness not exceeding 0.5 mm); tops of corrugations have notches in form of round holes having diameter of 0.5-1.0 of thickness of heat exchange surface. Besides that, notches are made in form of slots whose length is equal to 2.5-10, width is equal to 0.5-1.0 and distance between slots is equal to 5.0-10.0 of heat-exchange surface thickness and corrugations are made in one or two mutually perpendicular directions.
EFFECT: intensification of heat exchange process at retained serviceability in contaminated air medium through increase of area of heat-exchange surface at constant mass; increased thermal capacity of heat exchanger.
