The utility model object provides to overcome the deficiencies in the prior art the three chamber glass vacuum heat collection tube of solar energy that a kind of technique is simple, solar energy utilization ratio is high, mechanical strength is high, long service life, cost are low.
For achieving the above object, the technical solution adopted in the utility model is: a kind of three chamber glass vacuum heat collection tube of solar energy, comprise glass inner tube and outer glass tube, glass inner tube is coaxially fixed in outer glass tube by bracing frame I, vacuum interlayer is formed between glass inner tube and outer glass tube, the outer surface of glass inner tube is compounded with solar selective absorbing coating, by bracing frame II, coaxial or off-axis formula is fixed in glass inner tube inner bag, described inner bag is longer than glass inner tube and outer glass tube, support frame as described above I is provided with getter, outer glass tube forms air-breathing minute surface inside bracing frame I one end, described glass inner tube outer surface is formed multiple arc-shaped protruding.
Preferably, described glass inner tube outer surface forms pit shape pit.
Preferably, the vacuum interlayer backlight side of glass inner tube and outer glass tube is provided with aluminium sheet, and aluminium sheet is connected with glass inner tube outer surface by multiple Kato.
Preferably, described glass inner tube and outer glass tube are 3.3 high-boron-silicon glass.
Preferably, described solar selective absorbing coating is stainless steel aluminium nitride film.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages: after adopting said structure, both the problem that the glass inner tube efficiency of light energy utilization is low had been solved, the mechanical strength of glass inner tube can be improved again simultaneously, there is the features such as manufacturing process is simple, solar energy utilization ratio is high, mechanical strength is high, long service life, cost are low.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further.
Accompanying drawing 1 is a kind of three chamber glass vacuum heat collection tube of solar energy structural representations.
Wherein: 1, inner bag; 2, solar selective absorbing coating; 3, outer glass tube; 4, protruding; 5, glass inner tube; 6, bracing frame II; 7, bracing frame I; 8, getter; 9, air-breathing minute surface; 10, aluminium sheet; 11, vacuum interlayer.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Described in the utility model a kind of three chamber glass vacuum heat collection tube of solar energy as shown in Figure 1, comprise glass inner tube 5 and outer glass tube 3, glass inner tube 5 is coaxially fixed in outer glass tube 3 by bracing frame I7, vacuum interlayer 11 is formed between glass inner tube 5 and outer glass tube 3, the outer surface of glass inner tube 5 is compounded with solar selective absorbing coating 2, by bracing frame II6, coaxial or off-axis formula is fixed in glass inner tube 5 inner bag 1, described inner bag 1 is longer than glass inner tube 5 and outer glass tube 3, support frame as described above I7 is provided with getter 8, outer glass tube 3 forms air-breathing minute surface 9 inside bracing frame I7 one end, described glass inner tube 5 outer surface forms multiple arc-shaped projection 4, described glass inner tube 5 outer surface forms pit shape pit, the vacuum interlayer 11 backlight side of glass inner tube 5 and outer glass tube 3 is provided with aluminium sheet 10, aluminium sheet 10 is connected with glass inner tube 5 outer surface by multiple Kato, described glass inner tube 5 and outer glass tube 3 are 3.3 high-boron-silicon glass, described solar selective absorbing coating 2 is stainless steel aluminium nitride film.
Described in the utility model a kind of three chamber glass vacuum heat collection tube of solar energy as shown in Figure 1, glass inner tube 5 outer surface is made multiple arc-shaped projection 4, improve the mechanical strength of glass inner tube 5, thus the retractility can resisted preferably when expanding with heat and contract with cold, reduce pipe explosion, increase the service life, the area that more suitable day and night temperature is large uses.Meanwhile, glass inner tube 5 outer surface, by after blasting treatment, just defines scraggly pit on its surface, effectively can increase the endotherm area of solar energy vacuum tube, effectively can reduce the reflection of solar selective absorbing coating 2 pairs of sunshines on the other hand.
Described in the utility model a kind of three chamber glass vacuum heat collection tube of solar energy as shown in Figure 1, in use, openend is inserted in the heat-preserving container of solar water heater, the solar selective absorbing coating 2 of glass inner tube 5 outer surface is relied on to absorb solar energy, thus the water in heating glass inner tube 5.Hot water density reduces and automatically rises to the top of cistern, and the cold water automatic back flow bottom cistern adds in glass inner tube 5 chamber, circulates and so forth.
Described in the utility model a kind of three chamber glass vacuum heat collection tube of solar energy as shown in Figure 1, vacuumize process because vacuum interlayer 11 have passed through, so outwards the energy of scattering is little.Can reach best to make the effect of absorption solar energy, the most of solar selective absorbing coating 2 in glass inner tube 5 is made to absorb solar energy, the aluminium sheet 10 that 1mm is thick is added in the vacuum interlayer 11 of the shady face of thermal-collecting tube, by the reflex of aluminium sheet 10, thermal-collecting tube opaco can be made also can to absorb solar energy, greatly improve heat absorption efficiency.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
