ARCTIC CYLINDRICAL VACUUM SOLAR COLLECTOR Russian patent published in 2023 - IPC F24S10/40 F24S10/80 

FIELD: solar engineering.

SUBSTANCE: invention can be used in devices that convert solar electromagnetic radiation into thermal energy for heating a liquid coolant. Arctic vertical cylindrical vacuum tubular solar collector with an intra-volume heat absorption unit with a tangled wire coated with highly selective paint wrapped around the tubes of a direct-flow thermal channel installed in a translucent cylindrical tube, the latter being closed by the upper one for the hot liquid heat carrier and the lower one for the cold liquid heat carrier, disk-shaped tanks interconnected by parallel tubes of a direct-flow thermal channel coated with highly selective paint, placed along concentric radial circles around the axial heat pipe, coaxial to the axis of the translucent cylindrical pipe, and the intra-volume sunlight heat absorption unit consisting of a tangled wire placed between the tubes thermal channel and limited by an enveloping tangle of the outer radial circle of tubes of a direct-flow thermal channel.

EFFECT: increased optical efficiency and, accordingly, power and reliability.
