Abstract
The utility model provides an all-glass vacuum solar energy heat collecting pipe, relates to a heat collecting element. The heat collecting pipe mainly comprises an outer glass tube, an inner glass tube which is coated with an absorption coating layer, a vacuum interlayer which is arranged between the outer glass tube and the inner glass tube. The inner wall and the outer wall of the outer glass tube are coated with silicon dioxide anti-film coating. The heat collecting pipe has antireflection and easy cleaning functions, which can greatly improve the heat collecting efficiency of a solar energy hot water system.
Description
Technical field
The utility model relates to the heat collecting element of solar water heating system, particularly a kind of complete glass vacuum sun thermal-collecting tube that is applied in the domestic solar hot-water heating system.
Background technology
At present, one of key factor that influences all-glass vacuum tube domestic solar hot-water heating system efficient is the transmitance of vacuum tube surface light, and the dirt of vacuum tube surface deposition can directly have influence on light penetration and then influence the collecting efficiency of vacuum tube.Existing complete glass vacuum sun thermal-collecting tube mainly comprises cover glass pipe and inner glass tube on the market, is provided with vacuum interlayer between cover glass pipe and the inner glass tube, scribbles absorber coatings on the inner glass tube inwall.
Be accompanied by large-scale industrial production, thousands of ton industrial waste gases, dust, oil smoke enters in the atmosphere, make that the working environment of all-glass vacuum tube domestic solar hot-water heating system is more abominable, so the invasion and attack phenomenon that vacuum tube cover glass tube-surface seriously is subjected to all contaminations generally occurred, make vacuum tube use after a period of time, the pollutant that its surface deposition is a large amount of, badly influence the transmission of sunray, thereby cause transmitance seriously to descend a series of problems of degradation to cause solar water heater's collecting efficiency obviously to descend, serious will descend more than 50%, and this has influenced the Heat-collecting effect of complete glass vacuum sun thermal-collecting tube to a great extent.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned prior art, and a kind of precipitation that can effectively reduce pollutant is provided, and increases the transmitance of light, can significantly improve the complete glass vacuum sun thermal-collecting tube of the collecting efficiency of solar water heating system.
The technical scheme taked of the utility model is to achieve these goals: a kind of complete glass vacuum sun thermal-collecting tube, mainly comprise the cover glass pipe and scribble the inner glass tube of absorber coatings, be arranged on the vacuum interlayer between cover glass pipe and the inner glass tube, be coated with the silicon dioxide antireflective film coating on the inside and outside wall of described cover glass pipe.
The thickness of described silicon dioxide antireflective film coating is the 50-150 nanometer.
The silicon dioxide antireflective film coating has antireflective and antifouling function, has therefore realized the function integration anti-reflection and easy to clean of complete glass vacuum sun thermal-collecting tube.Through the test of national solar water heater quality supervision and test center, apply SiO
2Complete glass vacuum sun thermal-collecting tube transmittance after the antireflective film coating reaches 95%.
The beneficial effects of the utility model are: compared to existing technology, the utility model has adopted the structure that is coated with the silicon dioxide antireflective film coating on the inside and outside wall of cover glass tube outside, because the silicon dioxide antireflective film coating has antireflective and antifouling function, therefore realize the function integration anti-reflection and easy to clean of complete glass vacuum sun thermal-collecting tube, made the collecting efficiency of solar water heating system significantly improve.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is the A-A amplification view of Fig. 1.
Among the figure: 1 cover glass pipe, 2 vacuum interlayers, 3 inner glass tubes, 4 absorber coatings, 5 silicon dioxide antireflective film coatings.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
A kind of complete glass vacuum sun thermal-collecting tube shown in Fig. 1-2 mainly comprises cover glass pipe 1 and scribbles the inner glass tube 3 of absorber coatings 4, is arranged on the vacuum interlayer 2 between cover glass pipe 1 and the inner glass tube 3.Light transmittance and antifouling ability in order to increase complete glass vacuum sun thermal-collecting tube are coated with silicon dioxide antireflective film coating 5 on the inside and outside wall of described cover glass pipe 1.The thickness of described silicon dioxide antireflective film coating 5 is 50 nanometers, 75 nanometers, 100 nanometers or 150 nanometers.Because silicon dioxide antireflective film coating 5 has antireflective and antifouling function, therefore realized the function integration anti-reflection and easy to clean of complete glass vacuum sun thermal-collecting tube, make the collecting efficiency of solar water heating system significantly improve.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
