Zusammenfassung:	The utility model relates to a through type all-glass vacuum solar heat-collecting tube. A selective solar absorbing coating is coated on the outer surface of an inner glass tube of the through type all-glass vacuum solar heat-collecting tube. A getter welded with a supporting member into a whole body is arranged at one end in a cover glass tube. After the inner tube is sheathed with the cover tube, both ends are both melted and sealed into annular open ends. The utility model has the advantages that the through type all-glass vacuum solar heat-collecting tube can be arranged in any angle without worrying about thermal resistance; dirt in the tube can be conveniently cleaned; the through type all-glass vacuum solar heat-collecting tube can be applied to a large-area solar water heater and desalination engineering for preventing scale deposit and salt particle deposition; long-term accumulated water in the heat-collecting tube can be conveniently drained.
