Description
The present invention relates to a kind of vacuum heat collection pipe, particularly about utilizing solar energy to add the cheap vacuum heat collection pipe of hot water or air or solution or other fluid.
The inner glass tube that existing vacuum heat collection pipe mainly has spectral selective absorbing coating by the outer glass pipe and the outer surface of printing opacity or with the band wing or do not form with the interior metal tube suit sealing-in of the wing, the getter And that is equipped with or does not adorn belt supporting frame between inner and outer pipe is evacuated, as its spectral selective absorbing coating is many electrochemistry type coating or vacuum reaction type black chrome coatings such as black copper, black nickel, its shortcoming is a coating cost height, the manufacturing process complexity, can not large tracts of land produce continuously, cause vacuum heat collection pipe to involve great expense, be difficult to large scale application.
The objective of the invention is to provide about utilizing solar energy to add the cheap vacuum heat collection pipe of hot water or air or solution or other fluid.
The present invention is achieved in that the outer glass pipe of printing opacity (1) and outer surface to be had the inner glass tube (2) of spectral selective absorbing coating (4) or with the band wing or do not form with interior metal tube (2 ') the suit sealing-in of the wing, the two ends of interior pipe (2) and (2 ') are not sealed, but interior, welding sealing between outer tube (2) and (1) and (2 ') and (1) two ends mouth of pipe, shown in accompanying drawing (2) and (4), or in, each is self-enclosed for outer tube (2) and (1) and (2 ') and (1) same end, and welding sealing between the other end two mouths of pipe, shown in accompanying drawing (1) and (3), interior, getter (3) the And of belt supporting frame is housed or does not adorn between outer tube (2) and (2) and (2 ') and (1) and all be evacuated, cork or rubber stopper or other pipe close of band mozzle are housed on the port that does not seal, or pipe lid (6), it is characterized in that the inner glass tube (2) of this thermal-collecting tube or the band wing or be not by artificial Bepaint inorganic compound or natural painted mineral or metal inorganic pigment such as coloring oxide or corresponding hydroxide or painted salt under 1200 ℃～1400 ℃ high temperature sintering and describe agent with the spectral selective absorbing coating material of interior metal tube (2 ') outer surface of the wing, cementing agent is formed, and is by inorganic pigment under 500 ℃～900 ℃ low-temperature sintering, flux and describe agent and form.Its spectral selective absorbing coating material preferably selects for use black inorganic pigment such as light gorgeous black (being shallow gorgeous black) or dark gorgeous black or mixed black as basic chromonic material, select for use the bright material of pearl (raw material) to make the tone obfuscation unglazed, also the basic chromonic material of double as preferably selects for use local green (Jingdezhen porcelain produces with the chemical plant) or verdigris (being equipped with plumbous flux by cupric oxide) or chrome green (by Cr
2O
3Be equipped with plumbous boron flux) etc. green overglaze color material as toning material and double as flux, preferably select for use with the Arabic peach gum of water logging bubble or ox glue and water or frankincense oil and turpentine oil or syrup and materials such as water or tea juice as describing agent, select for use material such as solvent or feldspar or glaze under the glaze as the cementing agent under 1200 ℃～1400 ℃ high temperature sinterings preferably select for use leaded or flux that boron is plumbous as the flux under 500 ℃～900 ℃ low-temperature sinterings.
So-called flux is a kind of low-melting glass, its effect is the fusion temperature that reduces color material, make color material firmly glued on body surface, so-called cementing agent means and can make inorganic pigment can be bonded at material on the body surface after high temperature burns, and what is called is described agent and meant and inorganic pigment is flowed launch the material that does not at once condense.The so-called local green a kind of green tint material that contains cupric oxide that means that Jingdezhen porcelain is produced with the chemical plant.
The manufacture method of this vacuum heat collection pipe is such: ground black inorganic pigment (for example shallow gorgeous black) green or black overglaze color material (for example local green) and the bright material of pearl are prepared and describe agent (for example Arabic peach gum and water) or add or do not add cementing agent (for example feldspar) or add or do not add flux (both look heating-up temperature and select) evenly to mix, with methods such as infusion process or spraying process or spread coating with its coated on interior pipe (2) or (2 ') outer surface, through the natural airing or the oven dry of suitably heating, through sintering, in inciting somebody to action then, outer tube (2) is set with sealing-in with (1) or (2 ') and (1), interior, getter (3) the And that belt supporting frame is installed or do not adorn between outer tube (2) and (1) or (2 ') and (1) tube wall is pumped into and very becomes, on the port that does not seal, load onto cork or rubber stopper or other pipe close or the pipe lid (6) of band mozzle, just make vacuum heat collection pipe.
Owing to vacuumize, conduction and convection heat losses are reduced, again because of its fluid in interior pipe (2) or (2 ') siphons away heat, thus the radiation loss of interior pipe (2) or (2 ') outer surface selectivity absorbing coating material reduce a lot, thereby the collecting efficiency height of this vacuum heat collection pipe.
