SOLAR COLLECTOR Russian patent published in 2010 - IPC F24J2/24 F24J2/50 F24J2/51 

FIELD: heating.

SUBSTANCE: solar collector includes closed covering from transparent single-layered or multi-layered material L wide, which consists of central cylindrical surface with R radius, two side cylindrical surfaces with r radius, which are conjugated to it on its extreme edges, and the plane tangent to two side cylindrical surfaces, two end covers installed on edges of the cover, and flat heat-receiving panel H wide and t thick arranged in the cover and having selective absorbing coating and channels for passage of liquid heat carrier; at that, geometrical dimensions of the cover and heat-receiving panel are related with the following ratios: 5H≥R≥3H; 1.5t≥r≥(√2/2)t; 1.1H≥L≥1.05H. Flat heat-receiving panel is installed in the plane passing through two axes of side cylindrical surfaces of the cover of the collector, and additional heat insulation is installed in the area adjacent to side cylindrical surface of the cover and below longitudinal edge of flat heat-receiving panel throughout its length.

EFFECT: increasing operating efficiency of solar collector, improving its resistance to atmospheric actions.
