SECTIONAL RADIATOR Russian patent published in 2010 - IPC F24H3/00 

FIELD: heating.

SUBSTANCE: in sectional radiator of domestic heating system made of aluminium extruded profiles, which includes supply and discharge headers provided with offset channel of beak-shaped configuration in cross section, equipped with thickened support of trapezoidal shape and axisymmetrical tubular sections in the form of a tube, which are connected to them and having vertical heat-removing fins which are radial and axial, intermediate symmetrically bent fins and with two annular grooves in which there arranged are sealing rings, the thickened support of each header is provided with two shoulders triangular in section; at that, its end surface is provided with three grooves which are mainly sine-wave; on both sides of section, along axial fin on the length equal to thickness of transverse side of headers profile there pressed is plain tube with two annular grooves in which sealing rings are arranged. Attachment of each rear panel of section to side triangular shoulders of headers is provided with pressing of forge on rear panel of section to the slots between shoulders.

EFFECT: invention allows providing sealing, decreasing mass-and-dimensions parametres, easier assembly technology of radiator, increasing heat transfer from heat-removing fins, sections and power of specific heat flow, heightening natural convection.
