RADIATOR SECTION FOR CENTRAL WATER HEATING SYSTEM Russian patent published in 2002 - IPC

FIELD: heating systems; heating radiators. SUBSTANCE: radiator section includes pipe lines for flow of heat-transfer agent through radiator section and between radiator sections and heat-dissipating member made from aluminum alloy by pressure-die casting with devices for increase of heat exchange area which may include at least one fin. Pipe lines for handling heat-transfer agent are made from material possessing higher mechanical and/or corrosion resistance properties as compared with material of heat-dissipating member, from stainless steel in particular. These pipe lines are interconnected to form single member for passage of heat- transfer agent; provision is made for avoidance of contact of aluminum components of radiator sections with heat-transfer agent after interconnection of radiator sections. Ratio of passage area of pipe line used for passage of heat-transfer agent through radiator section to passage area of pipe line used for passage of heat transfer agent among radiator section ranges from 0.3 to 1.2. Heat-dissipating member forms in the course of pressure-die casting bimetallic part with above-mentioned single member for passage of heat-transfer agent. Device for increase of heat exchanger area may include at least one tennon of hyperbolic shape which is fitted on surface of heat-dissipating member. EFFECT: enhanced mechanical strength and corrosion resistance of each section separately and radiator as a whole; facilitated procedure of manufacture; reduced hydraulic resistance. 7 cl, 5 dwg
