Tower type vaccum solar heat collector

The invention relates to a tower type vaccum solar heat collector, and belongs to the technical field of solar power generation. The tower type vaccum solar heat collector mainly comprises a heat collector tower frame, a heat collector support, a light shielding ring, an air suction opening of an air suction switch, a heating tube support, a reflection ring and the like, and is characterized by further comprising a glass tube, a glass tube base body, a glass tube joint, a vacuum cavity defined by the glass tube, the glass tube base body and the glass tube joint and an S-shaped heating tube which is provided with fins and arranged in the vacuum cavity. According to the tower type vaccum solar heat collector, the main parts of the heat collector work in the vacuum condition, so that the heatloss of the heat collector in the natural environment is greatly reduced, the efficiency of the heat collector is greatly improved, and the manufacturing cost of the whole power generation station isgreatly reduced; and the
