Description

The through type glass vacuum solar collector tubes
The utility model relates to a kind of improved solar collector pipe, belongs to solar water heater's application component.
At present, complete glass vacuum sun thermal-collecting tube, Guan Yiduan is uncovered in it, the other end is for remaining silent, therefore, the water in the interior pipe can only form the convection current partial circulating after being absorbed the sunlight heating by the coating for selective absorption on the inner tube outer surface in thermal-collecting tube, water can not flow directly into and flow out thermal-collecting tube formation systemic circulation, so the thermal efficiency is subjected to very big influence.
It is a kind of scientific and reasonable for structure that the purpose of this utility model is to provide, the through type glass vacuum solar collector tubes that the thermal efficiency is high.
Through type glass vacuum solar collector tubes described in the utility model, outer glass pipe and inner glass tube are arranged, selective absorber coatings on the inner glass tube outer surface, it between the inside and outside glass tube laminated vacuum space, inner glass tube one end is uncovered, the other end also is uncovered, is provided with gap in the middle of the inner glass tube, and the glass tube on these gap both sides is connected by expansion alloy pipe, metal bellows, expansion alloy pipe successively.
The two ends of inner glass tube are uncovered, and therefore, heated water can flow directly into the outflow thermal-collecting tube in the inner glass tube, form systemic circulation, so thermal efficiency height.Owing to be connected with metal bellows in the middle of the inner glass tube, can eliminate inner and outer pipe because the stress that the difference of thermal expansion causes prevents bursting of thermal-collecting tube.The utility model is scientific and reasonable for structure, implements easily.
Described thermal-collecting tube, its metal exhaust tube can be connected on the metal segments of inner glass tube, and glass exhaust tube can be welded on the soldering opening of outer glass pipe, like this, can implement easily.
Be provided with routinely for other accessory of thermal-collecting tube that specification requirement gets final product, as being provided with of getter etc.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1, a longitudinal section schematic diagram of the present utility model.Also be an embodiment.
Among the figure: 1 outer glass pipe, 2 inner glass tubes, 3,5 expansion alloy pipes, 4 metal bellows, 6 coatings, 7 exhaust tubes, 8 getters.
As shown in the figure, through type glass vacuum solar collector tubes described in the utility model, outer glass pipe 1 and inner glass tube 2 are arranged, selective absorber coatings 6 on inner glass tube 2 outer surfaces, between the inside and outside glass tube 2,1 is the laminated vacuum space, the two ends of inner glass tube 2 are uncovered, are provided with gap in the middle of the inner glass tube 2, and the glass tube on these gap both sides is connected by expansion alloy pipe 3, metal bellows 4, expansion alloy pipe 5 successively.Metal bellows 4 is tightly connected by expansion alloy pipe 3,5 and inner glass tube 2 gaps, does not leak and reaches technologic enforcement requirement to guarantee the vacuum space.Expansion alloy pipe 3,5 and inner glass tube 2 weldings or with scolder welding, metal bellows 4 respectively with 3,5 welding of expansion alloy pipe.Glass exhaust tube 7 can be welded on the soldering opening of outer glass pipe 1, and getter 8 spot welding are fixed on the expansion alloy pipe and (also can put and be welded on the metal bellows).
The utility model is scientific and reasonable for structure, and cost is low, makes and implements easily, and is stable and reliable for performance, thermal efficiency height.
