FIELD: solar power engineering.
SUBSTANCE: invention relates to solar power engineering, and can be used in solar installations for conversion of solar energy into thermal energy, and is aimed at improvement of heat transfer efficiency. Solar collector contains multi-sectional heat exchangers in the form of coaxial glass tubes, in the annular space of which vacuum is created. Internal heat pipe inner tube accommodates metal heat pipe to circulate heat carrier. Tube ends are hydraulically connected with supply and discharge lines arranged on bearing racks in sectional housing. Sections of the body in plan view are made in the form of trapezium and are installed at an angle to support surface, at that, coaxial tubes of sections of each heat exchanger are installed in flanges at an angle relative to each other and at an angle to surface of section of housing. Adjacent body sections are interconnected on lateral sides of trapezoidal sections, and free ends of tubes are connected by ends of adjacent tubes in sections and with ends of tubes of adjacent sections, supply and outlet headers are located in housing, wherein in inner cavity of glass coaxial tubes there are heat corrugated tubes of U-shape.
EFFECT: higher efficiency of heat transfer.
