VERTICAL TUBULAR SOLAR COLLECTOR Russian patent published in 2023 - IPC F24S10/40 F24S10/55 F24S70/60 

FIELD: solar technology.

SUBSTANCE: invention relates to solar technology and can be used in devices that convert solar electromagnetic radiation into thermal energy for heating a liquid heat carrier, namely, vacuum solar collectors with an "internal heat absorption" unit. Solar vacuum collector with glass vacuum tubes containing an "internal heat absorption" assembly consisting of a heat channel heat pipe wrapped in a wire tangle, the heat channel tube with a highly selective coating having one radial protrusion at the ends with the ends of a fixing wire with a highly selective coating attached to them, wound on a wire tangle with a highly selective coating, and on the inner surface of the heat pipe with an arc length of not more than half the inner circumference of the heat pipe there is a reflector in the form of a reflective coating.

EFFECT: invention should increase power and reliability.
