SOLAR COLLECTOR WITH SOLAR RADIATION CONCENTRATOR Russian patent published in 2023 - IPC F24S10/40 F24S10/75 

FIELD: solar technology.

SUBSTANCE: invention can be used in devices that convert electromagnetic radiation from the sun into thermal energy to heat the liquid coolant. A solar vacuum collector with a coaxial vacuum tube comprising a thermal channel tube wrapped in wire, the tube and wire being coated with a highly selective coating, the wire wound in at least two layers and with a gap between the turns of at least two wire diameters, the ends of which are soldered to the opposite ends of the heat channel tube, whereas the solar collector is equipped with an external semicircular solar ray concentrator installed with a gap and parallel to the vacuum tube, made with a larger diameter than the vacuum tube and equipped with an end ring gear inserted into the mechanism for its rotation and fixation relative to the position of the sun independently from the vacuum tube.

EFFECT: increase in power and reliability by increasing the optical efficiency.
