Abstract
The utility model relates to an improved solar heat collecting pipe, which is a straight-through glass and metal vacuum solar heat collecting pipe which comprises an outer glass pipe and an inner metal pipe, wherein, interlayer vacuum space is arranged between the inner metal pipe and the outer glass pipe; both ends of the inner metal pipe are both provided with an opening, the middle of the inner metal pipe is provided with a metal bellows, and the near end parts of both ends of the inner metal pipe are welded with expansion alloy rings which are connected with the outer glass pipe in a sealing mode. The improved solar heat collecting pipe has the advantages of scientific and reasonable structure, easy fabrication and implementation, stable and reliable performance, convenient use and installation, and high heat efficiency.
Description
The utility model relates to a kind of improved solar collector pipe, belongs to solar water heater's application component.
At present, the glass metal vacuum solar collector tubes, metal tube one end is uncovered in it, the other end is for remaining silent, therefore, the water in the interior metal tube can only form the convection current partial circulating after being absorbed the sunlight heating by the coating for selective absorption on the interior metal 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, easy to use that the purpose of this utility model is to provide, the through type glass that the thermal efficiency is high, metal vacuum solar thermal-collecting tube.
Through type glass metal vacuum solar collector tubes described in the utility model, outer glass pipe and interior metal tube are arranged, selective absorber coatings on the interior metal tube outer surface, it between interior metal tube and the outer glass pipe laminated vacuum space, interior metal tube one end is uncovered, and the other end also is uncovered, has one section to be metal bellows in the middle of the interior metal tube, interior metal tube two ends close end is welded with the expansion alloy ring, and expansion alloy ring and outer glass pipe are tightly connected.
The two ends of interior metal tube are uncovered, and therefore, heated water can flow directly into the outflow thermal-collecting tube in the interior metal tube, form systemic circulation, so thermal efficiency height.Have one section in the middle of the interior metal tube and be metal bellows, metal bellows is used to regulate inner and outer pipe because the stress that the difference of thermal expansion causes prevents bursting of thermal-collecting tube, metal bellows can with the same material of interior metal tube, also can be unlike material.Realize being tightly connected by the method for expansion alloy between metal and the glass, do not leak to guarantee vacuum with scolder welding and welding.
Described thermal-collecting tube, metal tube end can be provided with screw thread or be welded with ring flange in it.Like this, bring great convenience to installing and using.
The load ability of interior metal tube is big, for solar water heater's improvement provides condition.
Be used on the solar water heater, interior metal tube should have antirust function, as stainless steel tube or copper pipe etc.
Be provided with routinely for other accessory of thermal-collecting tube that specification requirement gets final product,, on the metal tube, also can be located on the outer glass pipe in exhaust tube can be located at as being provided with of exhaust tube, 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 are an embodiment.
Among the figure: metal tube, 2,6 expansion alloy rings, 3 outer glass pipes, 4 metal bellows, 5 coatings, 7 exhaust tubes in 1.
As shown in the figure, through type glass metal vacuum solar collector tubes described in the utility model, outer glass pipe 3 and interior metal tube 1 are arranged, selective absorber coatings 5 on interior metal tube 1 outer surface, be the laminated vacuum space between interior metal tube 1 and the outer glass pipe 3, interior metal tube 1 two ends are uncovered, there is one section in the middle of the interior metal tube 1 and is metal bellows 4, interior metal tube 1 two ends close end is welded with expansion alloy ring 2,6, expansion alloy ring 2,6 and outer glass pipe 3 are tightly connected, and guarantee the vacuum of vacuum space.The end of interior metal tube 1 can add screw thread or welding flange again.Exhaust tube 7 is welded on the soldering opening of interior metal tube 1.
The utility model is scientific and reasonable for structure, makes and implements easily, and is stable and reliable for performance, easy to install and use, thermal efficiency height.
Claims (3)
1, a kind of through type glass metal vacuum solar collector tubes, outer glass pipe and interior metal tube are arranged, selective absorber coatings on the interior metal tube outer surface, it between interior metal tube and the outer glass pipe laminated vacuum space, interior metal tube one end is uncovered, and the other end of metal tube has one section to be metal bellows also for uncovered in it is characterized in that in the middle of the interior metal tube, interior metal tube two ends close end is welded with the expansion alloy ring, and expansion alloy ring and outer glass pipe are tightly connected.
