Abstract

The utility model discloses a mesothermal heat collector for an outer light-collecting solar vacuum tube, which comprises a vacuum tube and a reflecting light-collecting plate, wherein a heat absorbing body is arranged in the vacuum tube; and the reflecting light-collecting plate is arranged outside. The utility model is characterized in that the reflecting light-collecting plate is arranged at the side surface of the vacuum tube; the radial section of the reflecting light-collecting plate is in a type of symmetrical multisection circular-arc curved lines which respectively comprise two-section circular-arc curved lines, three-section circular-arc curved lines and seven-section circular-arc curved lines; the extension lines of the three-section circular-arc curved lines and seven-section circular-arc curved lines are intersected at the lowest point of the section circle of an inner heat absorbing pipe, and use a vertical line of the inner heat absorbing tube as the symmetric axis, and the vertical line of the inner heat absorbing tube passes through the circle center; and the extension lines of the two-section circular-arc curved lines are intersected at the lowest point of the section circle of an outer vacuum tube, and use a vertical line of the vacuum tube as the symmetric axis, and the vertical line of the vacuum tube passes through the circle center. The utility model has the advantages of simple reflecting plate shape, high light reflecting efficiency and low manufacture cost and can be widely used in solar mesothermal heat collectors.
