The outer surface of the heat absorbing body is provided with a high-temperature selective absorption coating. The utility model has the advantage of high absorption efficiency for the heat absorbing body. Solar radiation heat is converted into heat energy at a maximum degree. The utility model can be widely used for solar refrigeration, solar desalination, solar industrial heating, etc.
Description
The utility model relates to a kind of solar collector pipe.
Existing heat-pipe type vacuum solar heat-collecting pipe, generally be that a heat pipe absorber is set in glass tube, the heat pipe absorber is divided into evaporator section and condensation segment, vaporization after the working medium of evaporator section is heated, steam rises, condense after condensation segment discharges the latent heat of vaporization, condensed working medium relies on self gravitation to get back to evaporator section along internal face.This thermal-collecting tube is because absorber can only be the solar radiation that partially absorbs in the face of the sun, so the running temperature of thermal-collecting tube can not reach very high.Although some thermal-collecting tube can use outer concentrator,, generally do not adopt because cost price is higher.
The purpose of this utility model provides and a kind ofly can reach higher running temperature, and the lower again interior light collecting vacuum solar collector tubes of cost.
For achieving the above object, the utility model is taked following design: a kind of internal focusing vacuum solar collector pipe, it comprises glass tube, absorber, described absorber is divided into evaporator section and condensation segment, described absorber is fixedlyed connected with described glass tube, it is characterized in that: be fixed with the curved reflector as interior concentrator in the behind of the evaporator section of described absorber, described absorber outer surface has the high-temperature selective absorber coatings.
The shape of described curved reflector can adopt the two composite parabolic shapes that are connected.
Described absorber can be a heat pipe, also can be concentric tubes.
One end of described absorber and curved reflector adopts spring clip to support with adopting glass-metal hot-press sealing, the other end being connected of described glass tube.
The utility model is owing to be provided with curved reflector as interior concentrator at the back side of the absorber evaporator section of existing vacuum solar collector tubes, therefore can under the situation of not following the tracks of the sun, assemble solar radiation from different directions, simultaneously owing to be coated with the high-temperature selective absorber coatings on the surface of absorber, therefore can make absorber have higher absorptivity and lower emissivity, to greatest extent solar radiant energy is changed into heat energy, thereby greatly improved the Heat-collecting effect of condenser tube ferrule, make the operating temperature of thermal-collecting tube can be increased to 100-200 ℃, especially the utility model takes composite parabolic shape curved reflector as interior concentrator, and effect is more remarkable.The utility model can be widely used in solar refrigeration, solar seawater desalination, solar industry heating etc.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation
Fig. 2 is the utility model generalized section
Fig. 3 is a concentric tubes absorber schematic diagram
As shown in Figure 1 and Figure 2, the utility model comprises a glass tube 1, one heat pipe-type absorber 2.Absorber 2 is divided into heat pipe evaporator section 3 and heat pipe condenser section 4, and heat pipe condenser section 4 stretches out glass tube 1.In the glass tube 1 at heat pipe evaporator section 3 back sides, be provided with a curved reflector 5 as interior concentrator, the composite parabolic shape that the shape of curved reflector 5 can be made up of two parabolas that are connected, the shape of curved reflector 5 can also be other shape.One end of absorber 2 and curved reflector 5 adopts glass-metal hot-press sealing mode with being connected of glass tube 1, curved reflector 5 and glass tube 1, and the other end of absorber 2 and curved reflector 5 adopts spring clip to support.Outer surface at absorber 2 is coated with the high-temperature selective coating.Like this when shining upon, absorber 2 not only can directly absorb solar radiant energy, and can absorb project on the curved reflector 5 from different directions after, reflex to the solar radiant energy on the absorber 2 again, thereby greatly improved the running temperature of thermal-collecting tube.
In the foregoing description, absorber 2 also can adopt concentric tubes (as shown in Figure 3) to wait other cylindrical absorber, and being connected between absorber 2 and curved reflector 5 and the glass tube 1 also can be adopted other any connected mode of the prior art.
