Abstract
The invention relates to a novel tube-in-tube type glass vacuum tube. A hollow glass tube core is arranged in the inner glass of a double-layer glass vacuum tube. One end of the hollow glass tube core, positioned at the opening end of the double-layer glass vacuum tube, is wrapped in a heat insulation sleeve. The other end of the hollow glass tube core is fixedly connected with an inner glass tube. Because only very little water exists in the inner glass tube, the novel tube-in-tube type glass vacuum tube is rapid in heat start, low in heat radiation and high in energy efficiency; furthermore, because one end of the hollow glass tube core at the opening end is wrapped in the heat insulation sleeve, in the event of feeding cold water, the cold water cannot be in contact with the hollow glass tube core at the opening end, thus, the hollow glass tube core cannot be exploded.
Description
Technical field
The present invention relates to a kind of heat-collecting part glass-vacuum tube of solar water heater, can realize particularly that thermal starting is fast, heat radiation less, the glass-vacuum tube of high, the anti-explosion of efficiency.
Background technology
At present, the structure of existing tube-in-tube glass-vacuum tube is that it welds a cavity glass tube core in the inner glass tube of existing double-glass evacuated tube.When but the top of cavity glass tube core but is easy on solar water heater cold water by explosion.
Summary of the invention
The deficiency of easy explosion when overcoming cold water on the existing tube-in-tube glass-vacuum tube, the present invention provides a kind of novel tube-in-tube glass-vacuum tube, this novel tube-in-tube glass-vacuum tube thermal starting is fast, heat radiation less, high, the anti-explosion of efficiency.
The technical solution adopted for the present invention to solve the technical problems is: novel tube-in-tube glass-vacuum tube comprises inner glass tube, outer glass pipe; It between outer glass pipe and the inner glass tube low-voltage vacuum layer; The outer surface of inner glass tube scribbles heat-sink shell; One end of inner glass tube and outer glass pipe seals the formation free end respectively, and the other end of inner glass tube and outer glass pipe seals the formation openend, in inner glass tube, is provided with cavity glass tube core; An end that is positioned at the cavity glass tube core of open end is wrapped in collet, and the other end and the inner glass tube of cavity glass tube core are connected.A kind of prioritization scheme of such scheme does, between the cavity glass tube core of open end and inner glass tube, is provided with a bracing frame.
The present technique scheme is to realize its purpose like this, and heat-sink shell absorbs behind the sunlight energy heat is conducted in the inner glass tube that only contains water gaging seldom, and the water in the inner glass tube is by the water circulative convection in heating rapidly and the water tank; Be wrapped in collet owing to be positioned at an end of the cavity glass tube core of open end again, when last cold water, cold water can at first not touch cavity glass tube core, so cavity glass tube core can explosion.
The invention has the beneficial effects as follows only there is a spot of water in the inner glass tube, make that the thermal starting of novel tube-in-tube glass-vacuum tube is fast, heat radiation less, efficiency is high; Because an end that is positioned at the cavity glass tube core of open end is wrapped in collet, during last cold water, cold water can not touch the cavity glass tube core that is positioned at open end, so cavity glass tube core can explosion.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation of the novel tube-in-tube glass-vacuum tube among the present invention.
1. outer glass pipes among the figure, 2. inner glass tube, 3. low-voltage vacuum layer, 4. cavity glass tube core, 5. sealing-plug, 6. bracing frame, 7. collet.
The specific embodiment
In Fig. 1; Novel tube-in-tube glass-vacuum tube comprises inner glass tube 2, outer glass pipe 1, is low-voltage vacuum layer 3 between outer glass pipe 1 and the inner glass tube 2, and inner glass tube 2 outer surfaces scribble heat-sink shell; One end of inner glass tube 2 and outer glass pipe 1 seals the formation free end respectively; The other end of inner glass tube 2 and outer glass pipe 1 seals the formation openend, is provided with cavity glass tube core 4 in the inner glass tube 2, and an end that is positioned at the cavity glass tube core 4 of open end is wrapped in collet 7; And be provided with a bracing frame 6 between this end cavity glass tube core 4 and the inner glass tube 2, the other end and the inner glass tube 2 of cavity glass tube core 4 are connected through sealing-plug 5.
Claims (2)
1. novel tube-in-tube glass-vacuum tube; It comprises inner glass tube, outer glass pipe; Be the low-voltage vacuum layer between outer glass pipe and the inner glass tube, the outer surface of inner glass tube scribbles heat-sink shell, and an end of inner glass tube and outer glass pipe seals the formation free end respectively; The other end of inner glass tube and outer glass pipe seals the formation openend; It is characterized in that: in inner glass tube, be provided with cavity glass tube core, an end that is positioned at the cavity glass tube core of open end is wrapped in collet, and the other end and the inner glass tube of cavity glass tube core are connected.
