这种管是由硼硅玻璃的两层是特别困难的。 硼硅玻璃3.3是用于太阳能真空玻璃管的理想材料，因为它具有高的透明度，并能承受高温以及高压。
吸收体层涂有不锈钢，铝和铜在整个氮的环境。 选择性涂层更稳定时不锈钢，并将该吸收率较高。 由于铜比铝对减少红外线传导更有效，热量损失大大降低时铜涂覆作为该红外线反射层。
真空夹套这是高真空度是一种优良的绝缘材料。 它减少热损失并保护中的水冻结的管。
太阳能真空玻璃管甚至可以在恶劣的天气产生热水。 这就是为什么它是适用于地区和区域被用在非常寒冷或总是阴天。

This kind of tube is made of two layers of borosilicate glass which is specially hard. Borosilicate glass 3.3 is an ideal material for solar evacuated glass tube because it has high transparency and can withstand high temperature as well as high pressure.
The absorber layer is coated with stainless steel, aluminum and copper in an environment of entire nitrogen. The selective coating is more stable when stainless steel is added, and the absorptance is higher. Since copper is more effective than aluminum in reducing infrared conduction, heat loss is greatly cut down when copper is coated as the infrared-reflection layer.
The vacuum jacket which is of high vacuum degree is a kind of superior insulation. It reduces heat loss and protects the water in the tube from freezing.
Solar evacuated glass tube can produce hot water even in tough weather. That's why it is suitable to be used in areas and regions where is very cold or always cloudy.
