Abstract
The utility model provides an all-glass vacuum solar heat-collecting pipe with a plug, comprising an all-glass vacuum solar heat-collecting pipe composed of an inner glass pipe, an outer glass pipe, a selective absorbing coating, a vacuum interlayer, getter, a breathing film and a bracket, and a foamed plastic plug positioned inside the cavity of the inner pipe of the all-glass vacuum solar heat-collecting pipe. The utility model is characterized in that a foamed plastic plug of toothed surface is inserted in from the orifice of the all-glass vacuum solar heat-collecting pipe to the bottom of the cavity of the inner pipe, and a heat-transmitting interlayer is formed between the plug and the inner pipe; the other section of the foamed plastic plug projects out of the orifice of the all-glass vacuum solar heat-collecting pipe. The utility model has the advantages of that the water volume inside the cavity of the inner pipe is greatly reduced without narrowing the heat-absorbing area of water; besides, working weight of the heat-collecting pipe is reduced and thus waste of heat is tremendously decreased.
Description
Technical field the utility model relates to a kind of complete glass vacuum sun thermal-collecting tube, is the heat collecting element of solar water heating system, belongs to technical field of solar utilization technique.
Background technology is as the heat collecting element of solar water heating system, it is that wherein a kind of Fig. 1 is the structural representation of existing complete glass vacuum sun thermal-collecting tube that people use multiple vacuum heat collection pipe, wherein 1 is interior pipe, the 2nd, outer tube is a vacuum interlayer 3 between outer tube 2 and the interior pipe 1, the sealing of heat pipe one end, other end opening, interior pipe 1 and outer tube 2 annular sealing-ins, interior pipe 1 outer wall is coated with coating for selective absorption 4, is provided with support 5, getter 6, breathing film 7 in outer tube 2 bottoms.This complete glass vacuum sun thermal-collecting tube has Heat-collecting effect preferably.Chinese patent proposes a kind of complete glass vacuum sun thermal-collecting tube No. 200420052407.0, it is characterized in that being provided with on the outer tube wall reflector layer, and Heat-collecting effect is a kind of better than preceding.Above-mentioned two kinds of complete glass vacuum sun thermal-collecting tubes have common shortcoming: in when 1, using in the pipe cavity a large amount of water make its weight bigger, improved requirement to prop intensity, the cost of hot-water heating system is increased.2, because of the hot water in the interior pipe cavity can not cause heat waster for using, be that 47mm, length are that the complete glass vacuum sun thermal-collecting tube of 1500mm is an example with an internal diameter, be wasted because of using altogether with regard to the water of 1300 grams of having an appointment.
Light, the complete glass vacuum sun thermal-collecting tube that bolt is arranged that can reduce heat waster significantly of weight when summary of the invention goal of the invention of the present utility model provides a kind of the use.In order to reach goal of the invention, the utility model is by the following technical solutions: said complete glass vacuum sun thermal-collecting tube by bolt comprises the complete glass vacuum sun thermal-collecting tube of being made up of inner glass tube, outer glass pipe, selectivity absorption figure layer, vacuum interlayer, getter, breathing film and support, and the foamed plastic bolt that is arranged on pipe cavity in the complete glass vacuum sun thermal-collecting tube is formed.It is characterized in that: insert the foamed plastic bolt that there is tooth on a surface to interior pipe cavity bottom from the opening of complete glass vacuum sun thermal-collecting tube, and form the heat transfer interlayer between the interior pipe, another section of this foamed plastic bolt stretches out from the opening of interior pipe.
In order to reduce heat waster to greatest extent and weight when using, the volume of the heat transfer interlayer of the said complete glass vacuum sun thermal-collecting tube that bolt arranged be whole in the pipe cavity volume 1/10th to 3/10ths.
The utility model has the advantages that: during use, one section of the foamed plastic bolt in heat storage water tank (collector), its end is supported on the inwall of heat storage water tank (collector), has overcome buoyancy of water, make another section can be fixed in the cavity of pipe; Because filling effect in light weight, the foamed plastic bolt that do not absorb heat, a spot of water just can be full of the heat transfer interlayer between foamed plastic bolt and the interior pipe, neither reduce the heating surface area of water, can dwindle the volume of water in interior pipe cavity again significantly, the operating weight that has reduced thermal-collecting tube also reduces heat waster significantly.
Description of drawings Fig. 1 is the structural representation of the complete glass vacuum sun thermal-collecting tube of prior art.
Fig. 2 is that the A-A cutaway view also is a structural representation of the present utility model among Fig. 3.
Fig. 3 is a vertical view of the present utility model.
Fig. 4 is that the utility model is installed in the structural representation on the hot-water heating system.
Fig. 5 is an another kind of structural representation of the present utility model.
Specific embodiment Fig. 2 has provided an embodiment of the present utility model, is vacuum interlayer 10 between inner glass tube 8 and the outer glass pipe 9 among the figure, and inner glass tube 8 and outer glass pipe 9 connect envelope ringwise, its end sealing, other end opening.Inner glass tube 8 outer walls are coated with selectivity absorption figure layer 11, support 12, getter 13 and support 14 are installed in outer glass pipe 9 bottoms, foamed plastic bolt 15 surfaces have one section opening from inner glass tube 8 of tooth to be inserted into inner glass tube 8 cavity bottom, and form heat transfer interlayer 16 between the inner glass tube 8, foamed plastic bolt 15 another sections are stretched out from inner glass tube 8 openings.
Fig. 4 has provided the utility model and has been installed in situation on the hot-water heating system, wherein 18 is sealing rings, the 19th, the complete glass vacuum sun thermal-collecting tube of bolt is arranged, and the 15th, the foamed plastic bolt, its one section is in close-coupled heat storage water tank 17, and its end is supported on the inwall of heat storage water tank 17.
Certainly, the utility model has the foamed plastic bolt in the complete glass vacuum sun thermal-collecting tube of bolt to have solid and two kinds of structures of hollow seal, Fig. 2 has provided the structural representation of the complete glass vacuum sun thermal-collecting tube that bolt is arranged of foamed plastic bolt employing solid construction, and Fig. 5 has provided the structural representation of the complete glass vacuum sun thermal-collecting tube that bolt is arranged of foamed plastic bolt employing hollow seal structure.
