Description
Technical field
The present invention relates to solar energy heat collection equipment field, specifically light collecting collecting plate in a kind of whole-glass vacuum solar with bearing structure.
Background technology
There is following shortcoming in the existing most of flat-plate solar heat collector of China:
1, heaviness, thickness are all at more than 80mm.And be made up of the part such as transparent cover plate, collecting plate, heat-insulation layer, shell, very heavy, manufacture, transport, install take a lot of work, time-consuming, effort, expensive.
2, poor thermal insulation property, its insulation, solar collecting performance are all lower than vacuum tube, and can only obtain cryogenic energy, the winter of cold district cannot use.
3, service life is lower than vacuum tube.
And the shortcoming of existing vacuum pipe solar thermal-collecting tube is:
1, the Yanguan Pass between two pipes is not easy to be utilized.
2, diameter is large, cost is high.
3, be not easy to realize the perfect adaptation with building.
Therefore imagination can research and develop a kind of can with building perfect adaptation highly-efficient solar collecting device, wish that there is following features:
1, ultra-thin (below 16mm), Integral flat-plate, can random size and make type.
2, high temperature, high-absorbility, and high vacuum prevents heat leakage.
3, can to replace watt, decoration of exterior wall face, the anti-water surface in dull and stereotyped room.
Due to the effect of atmospheric pressure, just easily break if glass tube does not reach certain thickness, production cost increases, and therefore imagines and adds bearing structure at it and solve this problem outward.
Summary of the invention
For solving prior art Problems existing, spy provides light collecting collecting plate in a kind of whole-glass vacuum solar with bearing structure, by installing the vacuum tube of some inner and outer pipes composition in vacuum glass case, better, light utilization efficiency is high for its resistance to frost, thermal starting, heat-insulating property, volume is ultra-thin, quality is light, and cost is low, and daylighting area 100% can be utilized, can install on roof, wall and platform as glass, realize the perfect adaptation with building; Adding bearing structure outside it prevents glass tube from breaking.
The scheme that the present invention adopts:
Light collecting collecting plate in a kind of whole-glass vacuum solar with bearing structure, comprise plate body: in plate body, have some vacuum cavities, vacuum cavity upper and lower end face has arcwall face, gap location between vacuum cavity has laterally zygomorphic fan-shaped cavity, plate body corner place has circular hole, and the inwall of vacuum cavity both sides and bottom is equipped with aluminium reflecting layer, interior absorber plate is provided with in each vacuum cavity, described interior absorber plate has some glass-vacuum tubes arranged side by side to combine to form, each glass-vacuum tube is divided into outer tube and interior heat pipe, described outer tube is that clear glass is made, outer tube Lower Half is semicylinder, inwall scribbles internally reflective layer, the first half is take radius as height, diameter is wide cuboid, described interior heat pipe outer surface has selective absorbing film, interior inside heat pipe has heat-transfer working medium, it is outer as condensation segment that vacuum tube is stretched out in interior heat pipe one end, the other end is airtight head, between airtight head and outer tube, Spring Card is installed, Spring Card is provided with some getters.
Described plate body, interior heat pipe are Pyrex and make, and described getter is barium titanium getter; Described interior heat pipe is round tube, rectangular tube or square-outside and round-inside type pipe.
Described vacuum cavity vacuumizes, and has air in described circular hole, extracts vacuum out between described outer tube and interior heat pipe.
Advantage of the present invention is:
The present invention by some side by side in light concentration type full glass vacuum tube combine integrant evacuated panel, its resistance to frost, thermal starting, heat-insulating property are better, the efficiency of light energy utilization is high, volume is ultra-thin, quality is light, and cost is low, and daylighting area 100% can be utilized, can be arranged on roof, wall and platform as glass, realize and building perfect adaptation; Adding bearing structure outside it prevents glass tube from breaking.
