Service life of solar vacuum tube
The whole vacuum tube, life in 15 years, the whole vacuum tube, no leakage, the diameter of 102MM, is the future direction of the heat collector, there are also some say 102MM tube tube do not go, but remember that the internal structure is not the same as the true vacuum tube is blue heat absorbing German imports of copper the whole structure, copper, vacuum thermal conductivity is 1000 times at room temperature.
Sandwich vacuum, intraluminal water, life is more than ten years, but often used a few years later, due to scale down thickening, heat collecting effect. There are mainly 47, 58 and two, we used the same structure as the thermos bottle. The innermost layer has a layer of heat absorbing film.
