Abstract
The utility model discloses a full glass sheet type vacuum solar thermal collector, which consists of a sheet type inner glass tube and a sheet type outer glass tube. One end of the sheet type inner glass tube and one end of the sheet type outer glass tube are melted integrally, the other end of the sheet type inner glass tube and the other end of the sheet type outer glass tube are closed free ends, and a vacuum space is formed between the sheet type inner glass tube and the sheet type outer glass tube. The vacuum solar thermal collector is characterized in that the total thermal collector is in a sheet structure made of glass, and the outer surface of the sheet type inner tube is coated with a solar absorbing layer antireflective film. The inner glass tube is flat and has large thermal collection area, thereby improving thermal collection efficiency greatly and saving material cost. Since the integral thermal collector is in sheet type, difficulty and cost for links such as package and transport are also reduced. The thermal collector is suitable for water boilers, steam generators, solar water heaters and the like.
Description
Technical field
The utility model belongs to technical field of solar water heaters, designs a kind of full glass plate type evacuated solar collector, and it is applicable to boiler, steam generator, solar water heater etc.
Background technology
In order to overcome the low problem of the existing absorptivity of solar energy heat collection pipe, people have done many improvement to it.For example: Chinese patent 87210032 discloses " a kind of all glass vacuum heat collection tube of solar energy ", though it has the heat endurance that higher transmission-absorption is long-pending and applaud, but because the cross section of this solar energy heat collection pipe still adopts traditional circle, therefore in order to obtain bigger collector area, just need to use the thermal-collecting tube of greater number, the relatively large interior efficiency of heating surface of unit interval that caused of pipe volume is low in circular, and the solar energy heat collection pipe of cylinder body shape also has too many inconvenience in the packed and transported process.So the cost of this solar energy heat collection pipe, transportation, aspect reasons such as service efficiency have influenced its utilization and extention widely.
Summary of the invention
The purpose of this utility model is to provide a kind of full glass plate type evacuated solar collector, and it has bigger collector area, and the rapid and lower production cost that heats up in the unit interval is to overcome existing defective in the prior art.
Above-mentioned purpose of the present utility model is achieved in that a kind of full glass plate type evacuated solar collector, form by inner glass tube and outer glass pipe, one end sealing by fusing of inner glass tube and outer glass pipe is integral, the other end of inner glass tube and outer glass pipe seals the formation free end respectively, it between inner glass tube and the outer glass pipe vacuum, its key is: overall structure is board-like, scribbles the solar absorbing layer antireflective coating on the inner glass tube outer surface.
Full glass plate type evacuated solar collector described in the utility model, wherein this solar absorbing layer can be the aluminium copper film, or be bottom with the aluminium film, with gradual change copper-nitrogen composite is the solar selectively absorbing coating of absorbing material, being bottom with the aluminium film perhaps, is the solar selectively absorbing coating of absorbing material with gradual change copper-carbon-O compoiste material.
Full glass plate type evacuated solar collector described in the utility model wherein preferably scribbles antireflective coating on this solar absorbing layer.This antireflective coating can be copper-nitrogen-fluorine antireflective coating, is antireflective coating with copper-oxygen-fluorine perhaps.
Full glass plate type evacuated solar collector described in the utility model, wherein the thickness of this antireflective coating is preferably 50 * 10
-9M.
Full glass plate type evacuated solar collector described in the utility model is wherein set up the soft locating support of metal material between this inner glass tube and the outer glass pipe.
Description of drawings
Fig. 1 is the cross sectional representation of this full glass plate type evacuated solar collector;
Fig. 2 is the vertical section structure schematic diagram of this full glass plate type evacuated solar collector;
Fig. 3 is the local enlarged diagram of inner glass tube surface solar absorbing layer.
The specific embodiment
Below in conjunction with accompanying drawing shown in the embodiment, the utility model is described in further detail.
With reference to Fig. 1, the cross sectional representation of the full glass plate type evacuated solar collector that it is told for the utility model.Be made up of concentric plate inner glass tube 2 and board-like outer glass pipe 1, pipe scribbles on the 2 outer surface upper side planes between the solar absorbing layer 3 of solar absorbing layer antireflective coating 3.. and this board-like inner glass tube 2 and the board-like outer glass pipe 1 and is evacuated in board-like.
In conjunction with Fig. 2, the vertical section structure schematic diagram of the full glass plate type evacuated solar collector that it is told for the utility model.One end sealing by fusing of board-like inner glass tube 2 and board-like outer glass pipe 1 is integral, with shown in Figure 1 the same, on board-like inner glass tube 2 outer surfaces, scribble solar absorption antireflective coating 3, and be evacuated between the solar absorbing layer 3 of this board-like inner glass tube 2 and the board-like outer glass pipe 1.The other end of board-like inner glass tube 2 and board-like outer glass pipe 1 seals the formation free end respectively, and has additional locating support 5 between the free end of this board-like inner glass tube 2 and board-like outer glass pipe 1.
With reference to Fig. 3, on the outer surface of inner glass tube 2, scribble solar absorbing layer 3, this solar absorbing layer 3 is to be bottom with the aluminium film, is the solar selectively absorbing coating of absorbing material with gradual change copper-nitrogen composite.It can also be seen that from Fig. 3, also scribble antireflective coating 6 on this solar absorbing layer 3, this antireflective coating 6 is layer of copper-nitrogen-fluorine antireflective coatings.Because the concrete moulding process of solar absorbing layer 3 and antireflective coating 6 has detailed description in the prior art, so do not add narration at this.
By top explanation as can be known, the length of the active set hot side of solar energy heat collection pipe provided by the utility model and the solar energy absorbing coating of thermal-collecting tube determines that long more its heat collector surface of therefore board-like interior pipe catercorner length will be big relatively more.But consider the volume and the efficiency of heating surface problem of inner glass tube, board-like inner tube surface is long-pending to be not that the longer the better, so the board-like glass inner tube that cooperates the board-like outer tube of certain size to adopt size to be fit to, its area size is at 0.2m
2-4m
2Between, the length length of side ratio in the cross section is 1: 20-1: 200.
Because solar energy heat collection pipe cross section provided by the utility model is rectangle, so it has bigger collector area, and because just on the inner glass tube outer surface, scribble the solar absorbing layer antireflective coating, so its production cost is lower.
Because the solar absorbing layer antireflective coating told of the utility model has adopted in addition dash coat of nanometer technology, its thickness can be controlled at 50 * 10
-9Therefore m has preferable collector power.
Therefore the utility model has effectively overcome more existing open defects in the prior art owing to adopted said structure, can be at solar water heater, and utilization and extention widely in the products such as boiler and steam generator.
