Abstract
The invention relates to a 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. The distances from the hollow glass tube core to two ends of the inner glass tube are not less than 5 cm respectively. A support frame is respectively arranged between one end of the hollow glass tube core and the inner glass tube and between the other end of the hollow glass tube core and the inner glass tube. Because larger clearances exist from the hollow glass tube core to the two ends of 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 two ends of the hollow glass tube core during a short time, 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 no dirty explosion-proof tube-in-tube glass-vacuum tube, and this does not have, and the thermal starting of dirty explosion-proof tube-in-tube glass-vacuum tube is fast, efficiency is high, no incrustation scale, anti-explosion.
The technical solution adopted for the present invention to solve the technical problems is: do not have dirty explosion-proof tube-in-tube glass-vacuum tube and comprise 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; Cavity glass tube core and openend and free-ended distance are not less than five centimetres respectively, and respectively are provided with a bracing frame between the two ends of cavity glass tube core and the inner glass tube.
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.
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 no dirty explosion-proof tube-in-tube glass-vacuum tube is fast, heat radiation less, the efficiency height; Again because cavity glass tube core is not less than five centimetres apart from openend and free-ended distance; 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 in the short time, 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.
The specific embodiment
In Fig. 1; Do not have dirty explosion-proof tube-in-tube glass-vacuum tube and comprise inner glass tube 2, outer glass pipe 1; Be low-voltage vacuum layer 3 between outer glass pipe 1 and the inner glass tube 2, the outer surface of inner glass tube 2 scribbles heat-sink shell, and an 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, be provided with cavity glass tube core 4, cavity glass tube core 4 is not less than five centimetres respectively with openend and 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.
