Abstract
The invention relates to a novel tubular glass vacuum tube in a scale-free anti-explosion tube. A hollow glass tube core is arranged in the inner glass of the double-layer glass vacuum tube. Two ends of the hollow glass tube core are positioned in a heat insulation sleeve. The distance from the hollow glass tube core to the free end is not less than 5 cm. A support frame is respectively arranged between one end of the hollow glass tube core and an inner glass tube and between the other end of the hollow glass tube core and the inner glass tube. Water can smoothly flow in the inner glass tube; scale in the tube is easy to bring away by a rapid flowing water flow; furthermore, in the event of feeding cold water, the cold water cannot be in contact with the two ends of the hollow glass tube core, 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, relate to particularly that thermal starting is fast, no incrustation scale, prevent the tube-in-tube glass-vacuum tube of explosion.
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.Because there is incrustation scale narrow causing of space in a large number long-pending in the pipe in the pipe, and the explosion when being easy on solar water heater cold water of the top of cavity glass tube core.
Summary of the invention
The deficiency of easy explosion when having easy scaling of tube-in-tube glass-vacuum tube and last cold water now in order to overcome; The present invention provides a kind of novel nothing dirt explosion-proof tube-in-tube glass-vacuum tube, and the thermal starting of the explosion-proof tube-in-tube glass-vacuum tube of this novel nothing dirt is fast, efficiency is high, no incrustation scale, prevent explosion.
The technical solution adopted for the present invention to solve the technical problems is: the explosion-proof tube-in-tube glass-vacuum tube of novel nothing dirt 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, and an 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, be provided with cavity glass tube core; The two ends of cavity glass tube core are in the collet, and cavity glass tube core and free-ended distance are not less than five centimetres, and respectively are provided with a bracing frame between the two ends of cavity glass tube core and the inner glass tube.During work, 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.
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 vacuum tube is fast, heat radiation less, efficiency is high; Because the two ends of cavity glass tube core are in the collet and with free end certain distance is arranged again; It is smooth and easy to make that water flows in inner glass tube; Incrustation scale in the pipe is taken away by quick flowing water flow easily; And when last cold water, cold water can not touch the two ends of cavity glass tube core, 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 a structural representation of 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. bracing frame, 6. collet.
The specific embodiment
In Fig. 1; The explosion-proof tube-in-tube glass-vacuum tube of novel nothing dirt 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 the outer surface of inner glass tube 2 scribbles 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, in inner glass tube 2, is provided with cavity glass tube core 4, and the two ends of cavity glass tube core 4 are in the collet 6; Cavity glass tube core 4 is not less than five centimetres with free-ended distance, and respectively is provided with a bracing frame 5 between the two ends of cavity glass tube core 4 and the inner glass tube 2.
