Abstract
The invention discloses an all-glass vacuum straight-through forced circulation heat-collecting pipe which comprises an outer pipe and an inner pipe arranged inside the outer pipe, wherein both ends of the inner pipe are open, and both the outer pipe and the inner pipe are glass pipes; the outer pipe is corrugated; both the outer pipe and the inner pipe are made of borosilicate 3.3 glass or quartz glass; and the inner pipe is provided with a stainless steel aluminum nitride interference absorbing film layer. Because both ends of the vacuum pipe are open, the invention can realize the forced convective circulation of the heat collector and has the advantages of quick start and high thermal efficiency; by using the corrugated structure, the outer pipe can endure higher temperature without burst; and both the outer pipe and the inner pipe are of an all-glass vacuum structure, thereby ensuring that the cost is low. The invention can be widely used in various fields, such as solar water heaters, seawater desalination, heating air conditioners and the like.
Description
Technical field
The invention belongs to solar energy heating and utilize the field, particularly a kind of all-glass vacuum leads directly to the forced circulation thermal-collecting tube.
Background technology
Along with the attention of human society to environment, regenerative resource is as a new industrial field, more and more receive consumer's concern, the solar water heater industry is to utilize an important industry of regenerative resource (solar energy), its development had been made significant headway in recent years, on solar water heater, all-glass vacuum thermal-collecting tube has been widely adopted the heat collecting element as solar thermal collector.
Solar Heater Market adopts all-glass vacuum tube mostly to be greatly in a large number at present, and tube chamber is directly leaked water and relied on the mode of Natural Circulation heat exchange.
In realizing process of the present invention, the inventor finds that there is following problem at least in prior art: end sealing, there is the problem that thermal capacitance is big, startup is slow in the vacuum tube structure that an end is uncovered.Water tank water is not fully utilized with the intraluminal hot water in empty back, causes the water heater efficiency of utilization to reduce greatly.Because be Natural Circulation, because concerning, gravity sedimentation is easy to foreign material such as sediment incrustation, mud, colloid in the vacuum tube tube chamber, do not meet hygienic requirements.Tube wall incrustation is not only unhygienic, and the effective Natural Circulation and the heat that also can have influence on all-glass vacuum tube are imitated.
Summary of the invention
The purpose of the embodiment of the invention is the defective at above-mentioned prior art, provides a kind of startup fast, hot height, the straight-through forced circulation thermal-collecting tube of lower-cost all-glass vacuum of imitating.
The technical scheme taked of the present invention is to achieve these goals: a kind of all-glass vacuum leads directly to the forced circulation thermal-collecting tube, comprises outer tube and is arranged on interior pipe in the outer tube, described in pipe be both ends open, described outer tube and described in pipe be glass tube.
Have ripple on the described outer tube.
The material of described outer tube and described interior pipe is high borosilicate 3.3 glass or quartz glass.
Pipe is provided with stainless steel aluminium nitride interference absorbing membranous layer in described.
The glass ripple that described ripple is made for the method that adopts blowing, compacting, grinding tool to make or get rid of system.
The beneficial effect that the technical scheme that the embodiment of the invention provides is brought is:
The present invention is ordinary vacuum tube one end sealing, and the structure of an end opening becomes the dual channel structure of both ends open, has realized the forced convertion circulation of vacuum tube.The outer tube of vacuum tube of the present invention has also adopted ripple struction in addition, the expansive force of the line up that causes owing to interior tube swelling of well having releived.By sampling test result of the present invention is seen, empty solarization temperature reaches as high as 200 ℃ of mouths of pipe and is not burst.
The present invention has the following advantages:
1, both ends open can easily be realized heat collector forced convertion circulation, starts soon, and heat is imitated high.
2, forced circulation can effectively be improved impurity deposition in the water, clean and effective.
3, outer tube adopts ripple struction, can bear the higher temperature pipe explosion.
4, outer tube and interior pipe all adopt the all-glass vacuum structure, and cost is lower, processing easily, and can guarantee the vacuum life that vacuum interlayer is interior.
5, be widely used, can be widely used in every field such as solar water heater, desalinization, heating air conditioning.
Description of drawings
Fig. 1 is the full glass bilateral forced circulation thermal-collecting tube structural representation that provides in the embodiment of the invention;
Fig. 2 is the schematic diagram of the full glass bilateral forced circulation thermal-collecting tube endless form that provides in the embodiment of the invention.
Among the figure: 1, clamp, 2, getter, 3, outer tube, 4, interior pipe, 5, heat absorbing coating, 6, vacuum interlayer, 7, ripple.
The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of all-glass vacuum leads directly to the forced circulation thermal-collecting tube, comprises outer tube 3 and is arranged on the interior interior pipe 4 of outer tube, and interior pipe 4 is a both ends open, and outer tube 3 and interior pipe 4 are glass tube.Be vacuum interlayer 6 between outer tube 3 and the interior pipe 4, its vacuum is better than 5.0E-3Pa, is provided with getter clamp 1 in the vacuum interlayer 6, and getter clamp 1 mainly plays the carrying getter.Place getter 2 on the getter clamp 1, getter 2 adopts nonevaporable getter.Outer tube 3 is the glass outer tube, adopts high borosilicate 3.3 glass to make, and also can select quartz glass for use.Interior pipe 4 is a glass inner tube, adopts high borosilicate 3.3 glass to make equally.Interior pipe 4 is provided with coating for selective absorption 5, and coating for selective absorption 5 adopts the stainless steel aluminium nitride to interfere absorbing membranous layers; Have the anti-ripple 7 that expands on the outer tube 3, ripple 7 is formed through lamp worker blowing by the glass outer tube.The method that also can adopt compacting, grinding tool to make or get rid of system is made the glass ripple.
Concrete operation principle of the present invention: referring to Fig. 2, heat-conducting work medium (mobile working medium such as water or air) at first, externally enter under the effect of pressure (water pump or blower fan etc.) in the interior pipe of vacuum of full glass bilateral forced circulation thermal-collecting tube, solar irradiation gets above the coating for selective absorption to full glass bilateral forced circulation thermal-collecting tube, transform light energy is a heat energy, with the heating of the heat-conducting work medium that enters, the working medium of heating externally spreads out of at the other end under the effect of pressure, and heat energy is fully utilized.When full glass bilateral forced circulation thermal-collecting tube is worked, because interior pipe temperature is greater than the outer tube temperature, the expansion of therefore interior pipe is larger than outer tube, and this moment, well the releived expansive force of the line up that causes owing to interior tube swelling of the anti-ripple that expands that outer tube has above makes the mouth of pipe not by broken.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
