FIELD: heating engineering; central heating systems working on hot water, water steam, etc. SUBSTANCE: heating appliance consists of sections with tubular elements for heat-transfer agent, fins and holes for interconnecting them; sections are provided with inner radial fins and outer contour fins provided with upper, lower and longitudinal holes on both sides. Gaskets - agitators of heat-transfer agent flow are fitted at joints of sections; tubular elements of extreme sections are connected by means of branch pipe. EFFECT: high density of heat flow at reduced labor consumption and usage of materials. 2 cl, 3 dwg |
