Abstract
The utility model provides a novel low thermal radiation glass vacuum tube. An anti-thermal-radiation layer is arranged on one side of an outer surface of an outer glass tube. For the reason that the anti-thermal-radiation layer on the outer glass tube is used for reflecting sunlight to an inner glass tube and reflecting infrared ray emitted by the inner glass tube with high temperature back to the inner glass tube, so that the solar energy absorbed by the inner glass tube is increased, and the heat emitted to the outside in the inner glass tube is reduced at the same time.
Description
Technical field
The utility model relates to a kind of glass-vacuum tube of solar water heater, particularly to the low glass-vacuum tube of extraneous loses heat amount of radiation.
Background technology
At present, the heat-collecting part of solar water heater is mainly all-glass vacuum tube, and it is made up of inside and outside layer glass pipe, is low-voltage vacuum between the layer glass pipe, scribbles heat-sink shell at the outer surface of inner glass tube.All-glass vacuum tube mainly distributes a large amount of heats by thermal-radiating mode.
Summary of the invention
Distribute the deficiency of a large amount of heats to the external world by heat radiation for the heat-collecting part all-glass vacuum tube that overcomes prior solar water heater, the utility model provides a kind of novel low-heat radiant glass vacuum tube, this novel low-heat radiant glass vacuum tube can reduce effectively heat-collecting part by the heat radiation mode to extraneous distribute heat.
The technical scheme that its technical problem that solves the utility model adopts is: novel low-heat radiant glass vacuum tube comprises outer glass pipe, inner glass tube, 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 outer glass pipe and inner glass tube seals the formation free end respectively, the sealing of the other end of outer glass pipe and the other end of inner glass tube is provided with the anti-heat radiation layer in a side of the outer surface of outer glass pipe.
The technical program is to realize its purpose like this, because the side at the outer surface of outer glass pipe is provided with the anti-heat radiation layer, when daytime, solar irradiation was mapped to the anti-heat radiation layer, the anti-heat radiation layer arrived the heat-sink shell of inner glass tube with most of sunlight reflected, thereby had increased the absorption of solar energy; And when the inner glass tube of high temperature was outwards launched infrared ray by the heat radiation mode, the anti-heat radiation layer reflected infrared ray on the outer glass pipe distributed to the external world thereby reduced heat to inner glass tube.
The beneficial effects of the utility model are, anti-heat radiation layer reflected sunlight on the outer glass pipe is to the heat-sink shell of inner glass tube outer surface, also the infrared ray of the inner glass tube of reflected back high temperature emission distributes to the external world thereby also reduced heat when increasing the inner glass tube heat absorption.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a cutaway view of the present utility model.
1. outer glass pipes among the figure, 2. inner glass tube, 3. low-voltage vacuum layer, 4. heat-sink shell, 5. silver coating.
The specific embodiment
In Fig. 1, novel low-heat radiant glass vacuum tube comprises outer glass pipe 1, inner glass tube 2, 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 4, one end of outer glass pipe 1 and inner glass tube 2 seals the formation free end respectively, the sealing of the other end of the other end of outer glass pipe 1 and inner glass tube 2 is provided with the silver coating 5 of anti-heat radiation in a side of the inner surface of outer glass pipe 2.
Claims (1)
1. novel low-heat radiant glass vacuum tube, it comprises outer glass pipe, inner glass tube, 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 outer glass pipe and inner glass tube seals the formation free end respectively, the sealing of the other end of outer glass pipe and the other end of inner glass tube is characterized in that: the side at the outer surface of outer glass pipe is provided with the anti-heat radiation layer.
