ShanDong YaoGuo Solar Evacuated Tube

Product Description

What is Solar Vacuum Tube?

Solar vacuum tube is a main role of solar water heater as it play role as solar collector. It absorb and covert the solar energy to heat energy and transfer the heat to the water. It has prosperity of high absorption and low emission. The vacuum tube consists of outer tube, inner tube, (AL-N-SS-Cu) coating and holder.

What is AL-N-SS-Cu coating?

AL-NN-SS-Cu is coating for three target tube. Three target assimilate the advanced 12 layers of spattering deposition of trivalent element technology, high borosilicate glass, and gradual change of AL-N-SS-Cu selective complex absorptive coating. These make three target vacuum tube have high performance of absorption and low reflection ratio. Because of the coating, three target vacuum tube’s absorption rate increase 30%-50% than normal tube.

Product Advantages :

1) Excellent material: High borosilicate glass 3.3 is adopted as the raw material. 

2) High thermal efficiency: Pure vacuum layer without impurity. Degree of vacuum is high and lasts long, possessing extremely high absorption to sunlight with extremely low thermal emissivity. 

3) Small thermal losses: Higher degree of vacuum is kept between vacuum heat collection pipes, reducing thermal losses caused by heat conduction and heat convection to the maximum. 

4) Long life: Performance of film plated layer is stable, being not easy to ageing and attenuation. Processes in links of material selecting, production, transportation and quality inspection, etc. are strict with longer service life. 

5).Corrosion resistant: Performance against chemical corrosion is extremely good, appropriate to various kinds of water quality. 

6).High degree cold resistant: Even in high latitude in Northeastern China area with high degree cold temperature bitter cold, hot water can still be used normally, displaying super high heat collection rate.

The vacuum tube is the core of the solar water heater, his structure is like an elongated thermos bottle container, vacuum between the inner and outer layers. The surface of the inner glass tube is coated with a spectral selective absorbing coating on the surface of the glass tube to maximize the absorption of solar radiation energy. By sunlight, photon impact coating, solar energy into heat, water from the outside of the coating heat absorption, water temperature increases, the density decreases, hot water upward movement, and more than the major cold water drop. Hot water is always in the upper part of the tank.

A solar vacuum tube is mainly made of these parts:

1. Getter 2. Spring holder 3. Outer Tube 4. Inner tube 5. Vacuum 6. Anti-reflection layer 7. Absorbance layer 8. Infrared-reflection layer

After installation and check the heating collector system correctly, cold water is filled in the water tank. Due to gravity, cold water flowed into the vacuum tubes, absorbing the heat (which the temp. might reach 250 degree centigrade). Cold water changes into hot water and goes back to the water tank.
