Abstract
A through vacuum heat collecting tube with edge openings of two ends of an inner glass tube penetrating out is formed by two cover glass tubes and an inner glass tube which are sleeved together coaxially, and a sandwiched layer between the two glass tubes is vacuumed. A selective absorbing film is sputtered on the outer surface of the inner glass tube in vacuum mode. The through vacuum heat collecting tube is characterized in that two edge openings of the inner glass tube protrude out, two end openings of the cover glass tubes are bent inwards to the outer surface of the inner glass tube and in melt-sealing connection with the inner glass tube. The through vacuum heat collecting tube has the advantages that inner containers of a water heater or a collecting box can adopt smaller inserting holes when users manufacture a vacuum inserted type solar heat collecting device. Therefore, not only can tube spacing be shortened and effective heat gain on unit area of the heat collecting device be improved, but also heat radiating areas of the inner containers of the water heater or the collecting box can be reduced and heat preservation can be benefited. Users can further use a cover glass tube connecter to abut against the inserting holes of the inner containers of the water heater or the collecting box, and jacking force exerted at the tail portion of the heat collecting tube can be enlarged so that a pressure-bearing inserted tube type heat collecting device can be manufactured. An embodiment of the through vacuum heat collecting tube is showed in the attached drawing.
Description
Technical field
The utility model relates to the perforation vacuum heat collection pipe that inner glass tube two ends bead stretches out.
Background technology
Existing vacuum heat collection pipe heat-collecting temperature height, heat waste is little, industrialization level is high, can provide domestic hot-water more than 50 ℃ in the winter time with the cannula type water heater of its manufacturing.But generally speaking, the application product of vacuum heat collection pipe is abundant not enough flourishing.
Summary of the invention
The purpose of this utility model is that the inner glass tube two ends perforation vacuum heat collection pipe that bead stretches out will be provided.
The technical scheme in the invention for solving the technical problem: arrange with two glass tube cover glass tubes and inner glass tube nested, concentric, make that two beads of inner glass tube are protruding, two ports of cover glass tube inwards bending make the perforation vacuum heat collection pipe that an inner glass tube two ends bead stretches out to the inner glass tube outer surface and melt envelope with inner glass tube and be connected.Chuck layer between two glass tubes vacuumizes; Inner glass tube outer surface vacuum sputtering selective absorbing film.
The beneficial effects of the utility model: when making vacuum cannula type solar collector, the inner bag of water heater or connection collection box can adopt less jack.Both can dwindle effective heat that gets that tube pitch improves the heat collector unit are; Can reduce the area of dissipation of water heater or connection collection box inner bag again, help insulation.Can also utilize the cover glass tube interface to prop up the jack of water heater or connection collection box inner bag, strengthen jacking power at the thermal-collecting tube tail end and make pressure-bearing type intubate heat collector.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the perforation vacuum heat collection pipe structural representation that an inner glass tube two ends bead stretches out.
1. cover glass tubes among the figure; 2. inner glass tube; 3. bead.
The specific embodiment
Fig. 1 provides an embodiment of the present utility model.
Among Fig. 1, arrange, make 2 two beads 3 of inner glass tube protruding with two glass tube cover glass tubes 1 and inner glass tube 2 nested, concentric; 1 two ports of cover glass tube heat on the height of anger the lamp worker, bending is made the perforation vacuum heat collection pipe that an inner glass tube two ends bead stretches out to inner glass tube 2 outer surfaces and melt envelope with inner glass tube 2 and be connected inwards.Chuck layer between two glass tubes 1,2 vacuumizes by the blast pipe that is arranged on cover glass tube 1 outside and from envelope; Inner glass tube 2 outer surface vacuum sputtering selective absorbing films.
