Working Principle
EVACUATED tubes are the absorber of the solar water heater. They absorb solar energy converting it into heat for use in water heating. Evacuated tubes have been invented in China by Professor Yin Zhiqiang and have already been used for years in Germany, Canada, China and the UK. There are several types of evacuated tubes in use in the solar industry. Skylight uses the most common "twin-glass tube". This type of tube is chosen for its reliability, performance and low manufacturing cost.
EACH Skylight evacuated tube consists of two glass tubes made from extremely strong borosilicate glass. The outer tube is transparent allowing light rays to pass through with minimal reflection. The inner tube is coated with a special selective coating (Al-N/Al) which features excellent solar radiation absorption and minimal reflection properties. The top of the two tubes are fused together and the air contained in the space between the two layers of glass is pumped out while exposing the tube to high temperatures. This "evacuation" of the gasses forms a vacuum, which is an important factor in the performance of the evacuated tubes.
Advantages
1. Uni-directional heat transmission
2. Can start from lower temperature
3. Faster transmission
4. Lower heat capacity
5. Low temperature resistance
6. Freeze-proofing
7. High frequency soldering inner tank
8. Rating pressure is 0.6Mpa, 0.4Mpa separately, can connect directly with the city water system
9. No water in the vacuum tubes eradicates the incrustation scale, thus keeping them running in high efficiency,
10. No water in the vacuum tubes eradicates the leakage due to the aging of silica gel gasket or broken of the tubes,
11. No water in the vacuum tubes eradicate the frost cleft even in Jack Frost condition,
12. The whole system will still run even a single tube breaks,
13. Full automatic function,
14. Can realize pipeline evacuation
