Abstract
The utility model relates to a molecular-level ultrahigh-vacuum solar heat collection tube which is composed of an inner tube and an outer tube, wherein the inner tube is sleeved in the outer tube, a heat-absorption coating is formed on the outer wall of the inner tube, a supporting frame is installed at the bottom of the interlayer between the inner tube and the outer tube, a reducing layer is coated inside the bottom of the outer tube, and the vacuum degree of air in the interlayer is higher than 10<-4> Pa. According to the technical scheme, a molecular pump is used for vacuumizing the heat-collection tube, and the vacuum degree in the interlayer is higher than 10<-4> Pa after vacuumizing; and the reducing layer is coated inside the bottom of the outer tube, and is used for absorbing oxygen molecule in the residual air in the interlayer, so as to further improve the vacuum degree of the interlayer and protect the heat absorption coating from oxidation. In this way, the heat insulation and heat collection effects of the heat collection tube are greatly improved.
Description
Technical field
The utility model belongs to the solar energy heat collection equipment technical field, is specifically related to the higher molecular level ultrahigh vacuum solar energy Zijin pipe of a kind of vacuum.
Background technology
In solar energy heat collection equipment; Vacuum heat collection pipe is to utilize two different glass tubes of diameter to be sleeved on together; Make interlayer of formation between the inside and outside layer glass pipe later on through suit, seal an end of interlayer, the air the interlayer is taken out from the other end of interlayer; Seal the outer tube sintering then, make the inner state that forms near vacuum of interlayer; Scribble heat absorbing coating for improving on the outer wall that collecting efficiency manages in thermal-collecting tube.The height of vacuum in the interlayer of thermal-collecting tube is an important symbol of weighing the thermal-collecting tube quality, and vacuum is high more; The thermal-collecting tube heat insulation effect is good more; Interlayer adopts oil-sealed rotary pump in the prior art when vacuumizing, and the efficient that not only vacuumizes is low, and the heat-collecting pipe vacuum degree of producing is 10
-2-10
-3Between the Pa, vacuum is low, and the unnecessary easy oxidation heat absorbing coating of air in the thermal-collecting tube influences the thermal-arrest and the heat insulation effect of thermal-collecting tube.
Summary of the invention
The utility model is in the solar energy vacuum tube production process, and the heat-collecting pipe vacuum degree of existence is low, and heat absorbing coating is oxidized easily; Influence the problem of thermal-arrest and heat insulation effect, a kind of molecular level ultrahigh vacuum solar energy Zijin pipe is provided, its technical scheme is: a kind of molecular level ultrahigh vacuum solar energy Zijin pipe; Form by interior pipe and outer tube; Interior pipe box is contained in the outer tube, on the outer wall of interior pipe heat absorbing coating is arranged, and the interlayer bottom between interior pipe and the outer tube is equipped with bracing frame; The bottom inside of outer tube scribbles reducing zone, and the vacuum of interlayer air is higher than 10
-4Pa.
In the technique scheme, utilize molecular pump that thermal-collecting tube is vacuumized, the vacuum after vacuumizing in the interlayer is higher than 10
-4Pa; Because the bottom inside at outer tube scribbles reducing zone, makes it to absorb the oxygen molecule of surplus air in the interlayer, further improve the vacuum in the interlayer, the protection heat absorbing coating is not oxidized, and the insulation of thermal-collecting tube and Heat-collecting effect are greatly enhanced.
