The circumferential and coaxial heat exchanger, consisting of frame, ducts for supplied and discharged air, as well as fans, is characterized in that, it is made up of at least one internal diaphragm (1), situated coaxially with the external enclosure (2) and separating at least two tightly divided coaxial ducts (3) and (4) for the supplied and discharged air. The internal diaphragm (1), separating the air ducts (3) and (4) is made of material combining high thermal conductivity, resistance to corrosion and adequate strength parameters (preferably aluminium alloys), and the shape of its cross-section is corresponding to the to the shape of external enclosure (2). |
