The specific embodiment:
Below in conjunction with accompanying drawing shown in example, the present invention is described in further detail.
With reference to Fig. 1, the cross sectional representation of many inner tubes of all-glass vacuum communicate-type solar energy heat collection pipe that it is told for the present invention.Formed by a plurality of the inner glass tubes 2 on same plane and circular outer glass pipe 1, be evacuated between the solar absorbing layer 3 that scribbles solar absorbing layer antireflective coating 3.. and this inner glass tube 2 on inner tube 2 outer surface upper side planes and circular outer glass pipe 1.
In conjunction with Fig. 2, the vertical section structure schematic diagram of many inner tubes of all-glass vacuum communicate-type solar energy heat collection pipe that it is told for the present invention.One end sealing by fusing of a plurality of circular inner glass tubes 2 and circular outer glass pipe 1 is integral, with shown in Figure 1 the same, scribble solar absorption antireflective coating 3 on inner glass tube 2 outer surfaces, and be evacuated between the solar absorbing layer 3 of this inner glass tube 2 and circular outer glass pipe 1.The other end of inner glass tube 2 and circular outer glass pipe 1 seals respectively the formation free end.And a plurality of inner tubes bottom communicates with each other.
With reference to Fig. 3, scribble solar absorbing layer 3 on the outer surface of inner glass tube 2, this solar absorbing layer 3 is take the aluminium film as bottom, the solar selectively absorbing coating take gradual change copper-nitrogen composite as absorbing material.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 is described in detail in the prior art, so do not add narration at this.
By top explanation as can be known, effective collector area size of solar energy heat collection pipe provided by the present invention is decided by the area of the solar energy absorbing coating of thermal-collecting tube, consider volume and the efficiency of heating surface problem of inner glass tube, the number of inner tube and size have strict ratio requirement.
Because solar energy heat collection pipe cross section provided by the present invention is larger than the collector area of typical circular inner tube, and because the variation of diameter of inner pipe makes it to have water circulation conduction of velocity faster in heat exchanging process, and because just scribble the solar absorbing layer antireflective coating on the inner glass tube outer surface, so its production cost is lower.
The solar absorbing layer antireflective coating of telling due to the present invention has adopted nanometer technology dash coat in addition, and its thickness can be controlled at 50 * 10
-9Therefore m has better collector power.
Many inner tubes of all-glass vacuum communicate-type solar energy heat collection pipe diameter of inner pipe is 25mm to 45mm, and outer tube diameter is 58mm to 90mm.Basic compatible relevant the service of connection devices on the existing market.
Therefore the present invention has effectively overcome existing defective in prior art owing to having adopted said structure, can be at solar water heater, and utilization and extention widely in the products such as boiler and steam generator.
