Abstract
The utility model discloses an all-glass vacuum solar heat collecting pipe which comprises an internal glass oval tube and an external glass circular tube, wherein one end of the internal glass oval tube and one end of the external glass circular tube are sealed into a whole by fusing, the other end of the internal glass oval tube and the other end of the external glass circular tube are respectively sealed to form free ends, and vacuum exists between the internal glass oval tube and the external glass circular tube. The all-glass vacuum solar heat collecting pipe is characterized in that the cross section of the internal glass tube is oval, the cross section of the external glass tube is circular, and a solar absorbing layer anti-reflecting film is coated on the outer surface of the internal glass oval tube. The oval internal glass tube has a larger heat collecting area, therefore, the cost of the material is saved, the external glass circular tube overcomes the defect of poor hail resistance of the oval tube and the defect of difficult connection between the oval tube and the water tank, and the utility model is suitable for various products such as solar water heaters, water boilers, steam generators, and the like.
Description
Technical field
The utility model belongs to the solar water heater field, relates to a kind of all glass vacuum heat collection tube of solar energy, and it is applicable to solar water heater, boiler, steam generator etc.
Background technology
In order to overcome the low and economical with materials problem of the existing absorption efficiency 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 long-pending and heat endurance preferably of higher transmission-absorption, but because the cross section of this solar energy heat collection pipe still adopts traditional circle, more than ellipse with material, absorption efficiency is low.Again for example: Chinese patent 012632694 " all glass vacuum heat collection tube of solar energy " absorption efficiency height, consumptive material is few, but anti-hail deficiency.Be connected difficulty with water tank, influenced its utilization and extention widely.
Summary of the invention
The purpose of this utility model is to provide a kind of complete glass vacuum sun thermal-collecting tube, and pipe ellipse has bigger collector area and lower cost in it, and outer tube is circular to be connected difficulty with overcoming with water tank by anti-hail, to overcome the defective that exists in the prior art.
Above-mentioned purpose of the present utility model is achieved in that a kind of all glass vacuum heat collection tube of solar energy, form by interior glass elliptical tube and outer glass round tube, one end sealing by fusing of interior glass elliptical tube and outer glass round tube is integral, the other end of interior glass elliptical tube and outer glass round tube seals the formation free end respectively, be vacuum between interior glass elliptical tube and the outer glass round tube, its key is: the inner glass tube cross section is for oval, the outer glass pipe cross section is circular, scribbles the solar absorbing layer antireflective coating at interior glass elliptical tube outer surface.
All glass vacuum heat collection tube of solar energy described in the utility model, wherein this solar absorbing layer can be for the aluminium film or preferably is bottom, is the solar selectively absorbing coating of absorbing material with gradual change aluminium-nitrogen composite with the aluminium film, perhaps also can be to be bottom with the aluminium film, be the solar selectively absorbing coating of absorbing material with gradual change aluminium-carbon-O compoiste material.
All glass vacuum heat collection tube of solar energy described in the utility model wherein also preferably scribbles antireflective coating on this solar absorbing layer.This antireflective coating can be aluminium-nitrogen-fluorine antireflective coating, maybe can be aluminium-oxygen-fluorine antireflective coating.
All glass vacuum heat collection tube of solar energy described in the utility model, wherein the thickness of this antireflective coating is preferably 55 * 10
-9M.
All glass vacuum heat collection tube of solar energy described in the utility model, wherein this cross section is that the minor axis of oval-shaped inner glass tube and the ratio of major axis are preferably between 1:1.1～1:60.
All glass vacuum heat collection tube of solar energy described in the utility model can be set up locating support between the free end of glass elliptical tube and outer glass round tube in wherein being somebody's turn to do.
Description of drawings
Fig. 1 is the cross sectional representation of all glass vacuum heat collection tube of solar energy;
Fig. 2 is an all glass vacuum heat collection tube of solar energy absorbing surface vertical section schematic diagram;
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, it is the cross sectional representation of all glass vacuum heat collection tube of solar energy described in the utility model.Form by concentric oval inner glass tube 2 and circular outer glass pipe 1, at oblong inner glass tube 2 outer surfaces, scribble solar absorbing layer antireflective coating 3.And be evacuated 4 between solar absorbing layer 3 that should ellipse inner glass tube 2 and the circular outer glass pipe 1.
In conjunction with Fig. 2, it is the vertical section structure schematic diagram of all glass vacuum heat collection tube of solar energy absorbing surface described in the utility model.One end sealing by fusing of oval inner glass tube 2 and circular outer glass pipe 1 is integral, with shown in Figure 1 the same, scribble solar absorbing layer antireflective coating 3 at oval inner glass tube 2 outer surfaces, and be evacuated between solar absorbing layer 3 that should ellipse inner glass tube 2 and the circular outer glass pipe 1.The other end of oval inner glass tube 2 and circular outer glass pipe 1 seals the formation free end respectively, and should ellipse inner glass tube 2 and the free end of circular outer glass pipe 1 between have additional locating support 5.
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, to be the solar selectively absorbing coating of absorbing material with gradual change aluminium-nitrogen composite with the aluminium film.It can also be seen that from Fig. 3, also scribble antireflective coating 7 on this solar absorbing layer 3, this antireflective coating 7 is layer of aluminum-nitrogen-fluorine antireflective coatings.Because the concrete moulding process of solar absorbing layer 3 and antireflective coating 7 has detailed description in the prior art, do not give unnecessary details so do not add at this.
By top explanation as can be known, the length of the focal length of the eccentricity of the active set hot side of solar energy heat collection pipe provided by the utility model and ellipse, ellipse and the solar absorbing layer coating layer portion of thermal-collecting tube is determined, so flat more its active set hot side of ellipse is just big more.But consider the volume problem of oval inner glass tube, ellipse is not flat more good more, and the oval usually minor axis and the ratio of major axis preferably are controlled between 1:1.1～1:60.
Because pipe cross section ovalize in the solar energy heat collection pipe provided by the utility model, so it has bigger collector area, and consumable material is few again, so reduced production cost.
Because outer glass pipe adopts round tube, have anti-hail and convenient, water-tight with the water tank ease of connection, the oval and outer tube circle of interior pipe forms combination of advantages.
Because solar absorbing layer antireflective coating described in the utility model has adopted in addition dash coat of nanometer technology, its thickness can be controlled at 55 * 10
-9Therefore m has preferable collector power.
Therefore the utility model has effectively overcome existing defective in the prior art owing to adopted said structure, can be in products such as solar water heater, boiler and steam generator utilization and extention widely.
