The specific embodiment:
Below in conjunction with accompanying drawing shown in the example, the utility model is described in further detail.
With reference to Fig. 1, the cross sectional representation of the all-glass vacuum superconduction one thermal-collecting tube that it is told for the utility model.The many parallel weldings of inner glass tube are on same plane, and symmetry pipe number in the full coating film on glass of full glass sealing superconducting pipe both sides is 2 to 6.One group of inner glass tube 2 and the circular outer glass pipe 1 is made up of 2 to 6 coated glass pipes of a full glass sealing superconducting pipe and its both sides of symmetry are formed, are evacuated between solar absorbing layer 3 that scribbles solar absorbing layer antireflective coating 3. and this inner glass tube group 2 on one group of inner glass tube, the 2 outer surface upper side planes of 2 to 6 coated glass pipes compositions of full glass sealing superconducting pipe and symmetrical its both sides and circular outer glass pipe 1.
In conjunction with Fig. 2, the vertical section structure schematic diagram of the all-glass vacuum superconduction one thermal-collecting tube that it is told for the utility model.An one group of inner glass tube that symmetry is formed at 2 to 6 coated glass pipes of full glass sealing superconducting pipe both sides and an end sealing by fusing of circular outer glass pipe 1 are integral, the part of full glass sealing superconducting pipe and outer glass pipe 1 welding are with shown in Figure 1 the same, on inner glass tube group 2 outer surfaces, scribble solar absorption antireflective coating 3, and be evacuated between the solar absorbing layer 3 of this group inner glass tube 2 and the circular outer glass pipe 1.The other end of inner glass tube 2 and circular outer glass pipe 1 seals the formation free end respectively, and has additional locating support 5 between the free end of this group inner glass tube 2 and circular outer glass pipe 1.
With reference to Fig. 3, on the outer surface of inner glass tube group 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 active set hot side of solar energy heat collection pipe provided by the utility model is that the area by the solar energy absorbing coating of thermal-collecting tube decides, consider the volume and the efficiency of heating surface problem of inner glass tube, the number of interior pipe and size have strict ratio requirement.
Because solar energy heat collection pipe provided by the utility model has the simple manufacturing process of ordinary vacuum tube, also have the high characteristics of superconducting pipe collecting efficiency, adding material therefor is full glass, therefore not only have bigger collecting efficiency and manufacturing process simple, and because just on the inner glass tube outer surface, scribble the solar absorbing layer antireflective coating, so its production cost reduces greatly.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 existing defective 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.
