The specific embodiment
For shape of the present utility model, structure and characteristics can be understood better, below will enumerate preferred embodiment and also be elaborated in conjunction with the accompanying drawings.
Fig. 2 a and Fig. 2 b are the schematic diagram of first embodiment of the invention, shown in Fig. 2 a, comprise outer glass pipe 1 and inner glass tube 2, inner glass tube is the diameter unanimity about in the of 2, be sheathed in the outer glass pipe 1, the lower end of inner glass tube 2 is supported in the lower end of outer glass pipe 1 by inner glass tube supporting member 4.
The opening part of outer glass pipe 1 and inner glass tube 2 combines, and is vacuum between outer glass pipe 1 and the inner glass tube 2.Scribble absorber coatings on the inner glass tube 2, in order to absorb the energy of sunshine.The top of outer glass pipe 1 forms the reducing section, and promptly the diameter of outer glass pipe 1 top is less than the diameter of below, and the diameter at the feasible thermal-collecting tube mouth of pipe place that forms forms all glass vacuum heat collection tube of solar energy with reducing less than the diameter of pipe shaft below part.
Because the diameter at thermal-collecting tube mouth of pipe place diminishes, therefore when mounted, need the diameter in the hole beaten littler on the heat collector than in the past.So on the heat collector of same length, can beat more hole, on the heat collector more thermal-collecting tube can be installed.And because the diameter of pipe shaft does not diminish, so the space between the thermal-collecting tube pipe shaft diminishes, and it is more intensive that thermal-collecting tube also just can be installed.
Fig. 2 b is that of Fig. 2 a changes example, thermal-collecting tube structure among its thermal-collecting tube structure and Fig. 2 a is basic identical, difference is, inner glass tube 2 also has the reducing section, the diameter that is inner glass tube 2 tops is also less than the diameter of below, and the position of inner glass tube 2 reducing sections is corresponding with the position of outer glass pipe 1 reducing section.Interior outer glass pipe forms thermal-collecting tube of the present invention in the opening part combination.
Fig. 3 a and 3b are the schematic diagram of second embodiment of the invention, and in the present embodiment, the structure of thermal-collecting tube is basic identical among the structure of thermal-collecting tube and first embodiment, and difference is, is provided with internal lining pipe 3 in the thermal-collecting tube of second embodiment.The lower end of this internal lining pipe 3 combines with the lower end of inner glass tube 2, internal lining pipe 3 upper end closeds, and the length of internal lining pipe 3 is less than the length of inner glass tube 2, and the opening part that makes the upper end of internal lining pipe 3 and thermal-collecting tube is at a distance of certain distance.
With identical among first embodiment, outer glass pipe 1 among second embodiment has the reducing section, or interior outer glass pipe all has corresponding reducing section, makes the mouth of pipe place diameter of thermal-collecting tube less than the diameter of pipe shaft below part, therefore can be on heat collector more intensive installation thermal-collecting tube.
Fig. 4 a and 4b are the schematic diagram of third embodiment of the invention, in the present embodiment, the structure of thermal-collecting tube is basic identical among the structure of thermal-collecting tube and first embodiment, difference is, internal lining pipe 3 is housed in inner glass tube 2 in the present embodiment, described internal lining pipe 3 upper end closeds, the lower end of internal lining pipe 3 combines with the lower end of inner glass tube 2, and the length of internal lining pipe 3 equals the length of inner glass tube 2, makes the upper end of internal lining pipe 3 mutually concordant with the opening of thermal-collecting tube.
The length of the internal lining pipe among the 3rd embodiment is longer than the length of internal lining pipe among second embodiment, therefore can further reduce the inner space of thermal-collecting tube, reduces energy dissipation.
With identical among first embodiment, outer glass pipe 1 among the 3rd embodiment has the reducing section, or interior outer glass pipe all has corresponding reducing section, makes the mouth of pipe place diameter of thermal-collecting tube less than the diameter of pipe shaft below part, therefore can be on heat collector more intensive installation thermal-collecting tube.
All glass vacuum heat collection tube of solar energy of the present utility model, owing to make that the diameter of thermal-collecting tube opening part is littler than the diameter of pipe shaft below part, therefore can on heat collector, beat more hole, more thermal-collecting tube is installed, and reduce space between the thermal-collecting tube pipe shaft, make more intensive that thermal-collecting tube can install, increased solar energy utilization rate.
More than be illustrative to description of the present utility model; and it is nonrestrictive; those skilled in the art is understood, and can carry out many modifications, variation or equivalence to it within spirit that claim limits and scope, but they will fall in the protection domain of the present utility model all.
