Abstract
The invention provides an evacuated solar collector tube. The evacuated solar collector tube comprises a transparent outer tube body, an inner tube body arranged in the outer tube body, fixing pieces arranged between the outer tube body and the inner tube body and used for fixing the inner tube body and heat conducting fluid in-out openings allowing the outer tube body to penetrate and extending into the inner tube body. Each fixing piece comprises a supporting leg arranged between the inner tube body and the outer tube body and heat insulation mats arranged at the portions where the supporting leg is connected with the inner tube body and the outer tube body. The portion between the outer tube body and the inner tube body is vacuumized. The inner tube body is arranged in the outer tube body. The evacuated solar collector tube can replace an original evacuated solar collector tube used for solar heat collection projects and can be widely applied to the solar heat collection projects.
