SOLAR COLLECTOR WITH INTERNAL HEAT ABSORPTION UNIT Russian patent published in 2023 - IPC F24S10/40 F24S10/70 

FIELD: solar industry.

SUBSTANCE: used in devices that convert solar electromagnetic radiation into thermal energy for heating a liquid heat carrier, namely, solar collectors with an internal heat absorption unit. In a solar collector with vacuum tubes of a heat channel containing a heat pipe, the latter is wrapped in a film on a metal base, which has a one-sided highly selective coating up to the circumference of the heat pipe, and from a length beyond it has a double-sided highly selective coating and is cut into band rings.

EFFECT: increase in power and reliability by increasing the optical efficiency up to 45%.
