Description

A kind of solar energy collector in high efficiency vacuum tube
Technical field
The utility model relates to technical field of solar, specifically, relates to a kind of solar energy collector in high efficiency vacuum tube.
Background technology
Solar thermal collector is the equipment that a kind of radiant energy by the sun is converted to heat energy.Because solar energy compares dispersion, it must be managed to put together, solar energy vacuum tube is the essential core parts that solar thermal utilization gathers sunshine.Solar energy vacuum tube generally comprises outer glass tube and interior pipe, and the outer wall of interior pipe is coated with heat-sink shell, by aspirating into high vacuum state between inner and outer pipe interlayer.When sunshine is irradiated on the absorber coatings of interior pipe by outer glass pipe, be converted to heat energy, the heat-transfer fluid in heating in pipe.The outer tube of usual existing solar energy vacuum tube is transparent glass material, but the absorptivity of 50% is only had by the outer tube sunshine irradiated on inner pipe, because always there is the shady face of half not have light to irradiate on inner pipe, in addition, the selection of the upper coating of pipe also can affect the absorption to luminous energy, thus reduce the ability that interior pipe absorbs solar radiation, solar energy evacuated heat absorption efficiency can not be fully played, although vacuum serves good heat insulation effect, but or some heat energy dissipation, heat storage efficiency is lower.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of thermal transition efficiency is high, the solar energy collector in high efficiency vacuum tube of high insulating effect.
For solving the problems of the technologies described above, the utility model provides a kind of solar energy collector in high efficiency vacuum tube, comprise outer tube and interior pipe, the inwall of described outer tube is connected by hermetically-sealed construction with the outer wall of described interior pipe, forms vacuum layer between the inwall of described outer tube, the outer wall of described interior pipe and described hermetically-sealed construction; Described outer wall of inner tube is provided with heat-sink shell; Described outer tube wall is provided with nano thermal insulation layer, and described outer tube outer wall is provided with antireflection layer; Described nano thermal insulation layer surface is provided with the reflector layer that cross-sectional arc length is nano thermal insulation layer section girth 2/5ths; Described outer tube and described nano thermal insulation layer are light transmissive material and make.
Further, described outer tube and interior pipe are made by high-boron-silicon glass material.
Further, described heat-sink shell is cupric oxide, black nickel, black chromium, black zinc or black copper one wherein.
Further, described nano thermal insulation layer is metal nano powder coating.
Further, described antireflection layer is SnO 2film.
Compared with prior art, a kind of solar energy collector in high efficiency vacuum tube structure of the present utility model is simple, sunlight is by continuing through outer glass tube after antireflection layer, then be irradiated on heat-sink shell by nano thermal insulation layer, the heat that heat-sink shell absorbs passes to glass inner tube, and then the water in glass inner tube is heated, vacuum layer has organized scattering and disappearing of a part of heat, nano thermal insulation layer has further stopped scattering and disappearing of heat, efficiently solve insulation and structural behaviour safe and reliable, the regenerator temperature of conventional vacuum pipe can be made to be increased to 200 DEG C by this improvement, extend its scope of application, also add reflector layer simultaneously, sunlight is reflexed to the side of sunless glass inner tube, make glass inner tube 360 degree to carry out accumulation of heat, greatly improve the heat storage efficiency of vacuum tube.
