Description
Technical field
The utility model relates to technical field of solar, specifically, relates to a kind of heat collector 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, the heat absorption efficiency of solar energy vacuum tube 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 heat collector vacuum tube of high insulating effect.
For solving the problems of the technologies described above, the utility model provides a kind of heat collector 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, and described inner tube wall is provided with anti-stick coating; 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 1/3rd, and described nano thermal insulation layer surface is provided with some Fresnel Lenses at the opposite side relative with described reflector layer; Described outer tube and described nano thermal insulation layer are light transmissive material and make.
