Solar Vacuum Tube Suppliers and Manufacturers

Super Heat-Conducting Tube is consists of the glass tube and copper pipe. The temperature can be more 300 in the tube. Features: 1) High heat effectiveness: higher than all glass evacuated solar collector tube by 15%. 2) heat pipes conduction: successfully prevents the defects of tube breakage and low power output caused by water fouling and deposits or dust and sand. 3) Prevents the tube from being easily broken caused by volume expansion when water freezes in the frigid season. 4) Low thermal capacity makes the tube start up quickly. 5) Energy output of sunshine within only 2 minutes. 6) Insulation temperature can reach 250, average heat efficiency can still be more than 50%; even under -50. 7) High efficient selective absorptive coatings and vacuum heat insulation technology ensure the tube has higher heat output in cloudy weather and in moist areas, especially in winter. 8) Solar collecting plate is sealed inside a high quality borosilicate glass tube with 5 x 10 - 3Pa of vacuum, to stop corrosion; even in moist conditions. Metal-glass evacuated solar collector tube consists of a single glass tube and a flat or curved aluminum plate inside attached to a copper heat pipe.

Difference between three high efficiency solar vacuum tube (effective tubes, high cold tube, high temperature special efficiency tube)and ordinary tube: Absorption of heat membrane layer is difference between these two kind of tubes. (Absorption of heat membrane layer is the key part of vacuum tubes.) Absorption of heat membrane layer of three high efficiency solar vacuum tube is interference membrane, common tube is gradient membrane. The difference is mainly for interference membrane and the gradient membrane distinction. 1. Fundamental distinction: membrane layer structure is different, the principle of the absorption of sun's rays result in differently. gradient membrane, for multilayer, its absorbing layer is generally 9 layers. It to the sun's rays are layered absorption, and its absorb the light performance gradually become tall. Because the gradient structure, launch with increasing temperature rise than work, that temperature in 300 to 500 C than when launch greatly increased. The aluminum ions and absorbing layer in high temperature condition, lively nature greatly enhance the, and develop a drift. This happened in the internal structure of membrane layer caused confusion, coating began to aging. In the long run, the high temperature condition, membrane layer can fall off, thereby affecting the vacuum tube heat efficiency and life integrating. Interference membrane, its absorbing layer altogether 2 layer, among two layer membranes, because the metal content between the different and interfere ratio effect, make absorption ratio increase, launch ratio decrease. Plus effect of reduce emission from minus reverse layer, thus achieve more higher absorptance and reducing the role of launch ,greatly improved collection thermal efficiency. 2.Features: Absorptance of three high efficiency solar vacuum tube increased by 12%, and launch reduced by 30 to 40 percent, the super absorbing, heat loss less, warming faster. Efficient tube, the super absorbing, thermal efficiency is high, warming faster, in the same light conditions, can create more and higher temperature water than common tubes ; high cold tube, copper ions for the launch of aluminum ion mantua, so low 0.2 thermal loss rarely, in high cold environment can still work normally. hot water turn out as usual under- 30 C. high temperature special efficiency tube, because the membrane layer stainless steel ion high temperature resistant, fight air drying. Membrane layer under the condition of the 400 C, not attenuation, not aging, discoloration. In the same light conditions, ordinary tube heat absorption is lower than three high efficiency solar vacuum tube, can't even meet requirements that wash bath; In lower temperature, heat loss is bigger, collection hot effect is reduced, affect the normal use; Especially in the empty sun over 270 C, membrane layer began to aging, fall off, absorption rate drastically reduce, life shortens greatly. 3.Technology: high temperature special effects tube, high cold tube, efficient tube used respectively to three target, double target, single target magnetron sputtering craft; Ordinary tube typically use the single target magnetron sputtering technology. 4, appearance: A, Mouth of tube, here membrane layer above 800 C high temperature condition sealing off part is inevitable. As high temperature special effects tube has high temperature resistant, only 1 cm long without membrane layer in mouth of tube, while others without membrane layer for without high temperature resistant, tube membrane layer falls off the length is about 2.5 cm B, Inner tube color: with macroscopic observation, high-temperature tubes and high cold tube for internal color is kermesinus (for membrane layers bottom is copper); the bottom And efficient tube and ordinary tube are white (for membrane layer bottom is aluminum). Anyhow, interference membrane is the new breakthrough basis of gradient on membrane technology ,it is the great innovation in coating technology progress and become current global, interference coating of the most advanced coating technology. But also to the vacuum coating technology bring epoch-making change. Especially with the high temperature effects made interference membrane, can also be used for cooling tube, dry, seawater desalination, opened up the update for vacuum tubes wider application fields.
