Abstract
A through-type full-glass vacuum solar heat-collecting tube is characterized in that the outer surface of an inner glass tube is plated with a solar selective absorption coating, one end in a cover glass tube is provided with a getter welded with a support piece into a whole, and the two ends of the inner tube are all sealed into an annular opening end after being sleeved with the cover tube. The utility model can be installed at any angle without worrying about thermal resistance, is convenient to clean dirt in the pipe, can be applied to large-area solar water heaters and seawater desalination projects to prevent scale and salt particle deposition, and is convenient to drain long-term accumulated water in the heat collecting pipe.
Description
The utility model belongs to glassware, is specifically related to a kind of structure of through complete glass vacuum sun thermal-collecting tube.
The vacuum heat collection pipe that prior solar water heater adopts is made of inner glass tube with solar selective absorbing coating and coaxial cover glass tube, inner glass tube one end seals into top, garden shape, getter in the cover glass tube blind end is by supporting members support, the inner glass tube other end and cover glass tube other end sealing by fusing are the circular opening end, the thermal-collecting tube of this structure has only an openend, in order to make the heat transfer medium in the pipe successfully carry out the thermal convection current circulation, all openend is made progress in actual use, the vacuum tube of this form exists the circulation of intraductal heat transfer medium heat not smooth, the emptying difficulty, problems such as the difficult cleaning of fouling.
The purpose of this utility model is: design a kind of through complete glass vacuum sun thermal-collecting tube, its rigging position is not limit, Heat-collecting effect is good, is applicable to applications such as large tracts of land solar water heater engineering and desalinization engineering.
The purpose of this utility model is achieved in that the cover glass tube coaxial package that installs the supporting member that is welded with getter in the inner glass tube of outer surface plating solar selectively absorbing coating and the end additional, with the whole sealings by fusing in its two ends openend circlewise, form the tubular structure that connects.
Fig. 1 is the utility model structural representation
Fig. 2 is the structural representation of existing vacuum solar collector tubes
Among the figure: 1 is that inner glass tube, 2 is that solar selective absorbing coating, 3 is that interlayer, 4 is that cover glass tube, 5 is that supporting member, 6 is getter.
Introduce implementation method of the present utility model below in conjunction with accompanying drawing:
Outer surface plating solar selective absorbing coating 2 at inner glass tube 1, have in the end of cover glass tube 4 of the mouth of bleeding and load onto the annular support spare 5 that is welded with getter 6, inner glass tube 1 coaxial package goes into to form interlayer 3 in the cover glass tube 4, the inner glass tube 1 that will not have supporting member one end earlier is the circular opening end with cover glass tube 4 sealings by fusing, annealing in process is eliminated the stress at sealing by fusing place, it is the circular opening end with cover glass tube 4 sealings by fusing that the inner glass tube 1 of supporting member end will be arranged again, annealing in process is eliminated the stress at molten envelope place simultaneously, then vacuumize, sealed-off, operations such as baking getter, the thermal-collecting tube of making so as shown in Figure 1, for having the tubular structure of two openends.
Therefore the utility model has following advantage because both ends open: 1, can arbitrarily angled installation and needn't worry to produce thermal resistance; 2, the dirt in the easy to clean pipe is applied to can effectively prevent on large tracts of land solar water heater engineering and the Seawater Desalination Project incrustation scale and salt grain deposition; 3, be convenient to the interior long-term ponding of emptying thermal-collecting tube.
