FIELD: heat exchange.
SUBSTANCE: invention relates to heat recovery devices and can be used for recycling exhaust heat energy in air-and-exhaust ventilation and air conditioning plants. Invention consists in the fact that cylindrical recuperative heat exchanging device of coaxial type, including cylindrical housing; channels with plugs, supply and discharge air ducts, additionally includes annular plates forming central axial channel and annular channels with end plugs; longitudinal arc elements; flanges; sealing rubber interlayer between flanges; flanging with holes for bolts with nuts; a longitudinal partition separating the supply air duct and the discharge air duct, turbulence promoters formed by the convex elements, wherein between annular plates there is a device of longitudinal arc elements lengthwise swirling air flows and increasing time of contact of heating medium with heat exchange elements, and on surface of annular plates facing axis of cylindrical housing, as a result of application of contact high-heat-conducting coating, roughness is formed, which, when combined with turbulence promoters, causes transverse whir of air flows.
EFFECT: intensification of heat exchange.
