Abstract
The utility model relates to a novel tube-in-tube type glass-vacuum tube. A hollow cavity glass tube core is arranged in an inner glass of a dual-layer glass vacuum tube, one end of the hollow cavity glass tube core at the opening end of the dual-layer glass vacuum tube is wrapped in a heat insulation jacket, and the other end of the hollow cavity glass tube core is fixedly connected with the inner glass. As little water is stored in the inner glass tube, the tube-in-tube type glass-vacuum tube is fast in warm start, less in radiation, and high in energy efficiency; as one end of the hollow cavity glass tube core at the opening end of the dual-layer glass vacuum tube is wrapped in the heat insulation jacket, cooled water is not contacted with the hollow cavity glass tube core at the opening end when being supplied, so that the hollow cavity glass tube core does not explode.
Description
Technical field
The utility model 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 efficiency height, anti-explosion.
Background technology
At present, the structure of existing tube-in-tube formula 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 formula glass-vacuum tube, the utility model provides a kind of novel tube-in-tube formula glass-vacuum tube, this novel tube-in-tube formula glass-vacuum tube thermal starting is fast, heat radiation less, efficiency height, anti-explosion.
The technical scheme that its technical problem that solves the utility model adopts is: novel tube-in-tube formula 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, 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, 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 is, is provided with a bracing frame between the cavity glass tube core of open end and inner glass tube.
The technical program is to realize its purpose like this, and heat-sink shell absorbs behind the sunlight energy and heat to be 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 beneficial effects of the utility model are, only have a spot of water in the inner glass tube, make that the thermal starting of novel tube-in-tube formula glass-vacuum tube is fast, heat radiation less, the efficiency height; 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 drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the novel tube-in-tube formula glass-vacuum tube in the utility model.
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 formula glass-vacuum tube comprises 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, 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, be provided with cavity glass tube core 4 in the inner glass tube 2, 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 by sealing-plug 5.
Claims (2)
1. novel tube-in-tube formula glass-vacuum tube, it 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, 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.
2. novel tube-in-tube formula glass-vacuum tube according to claim 1 is characterized in that: be provided with a bracing frame between the cavity glass tube core of open end and inner glass tube.
