La description

The solar tube is made from borosilicate glass 3.3 and the structure of solar vacuum tubes is as same as the gallbladder of the pot, which is sealed with double glass and the double glass tube is pumped into a high-vacuum. The surface of inner glass is sprayed with selective coating through a special technology. The solar energy absorption rate can reach *4.5percent by the usage of the selective coating, while the rate of thermal radiation below 5.5percent. Vacuum tube absorbs solar energy, and then heats the water or liquid by heat conduction. The heat loss of liquid is very low through the high-vacuum between inner glass tube and outside, Its stagnation temperature is above **0 degrees. It is widely used in solar water heater, solar collecotor, solar projects. Specification Outer Diameter and Inner Diameter (MM) *7 / *7 *8 / *7 Length of Tube (MM) ***0, ***0, ***0, ***0 Thickness of Tube (MM) 1.*0 more or less 0.*5 Selective absorbing surface: 3layers, aluminum-nitrogen-carbon (Al-N-C) Material: Borosilicate glass 3.3 Color: Blue Thermal Expansion: 3.3 multiply ***6 / k Maximum Strength: 0.6 Mpa Absorption of Selective Coating: Above *5 percent Emission of Selective Coating: Below 5 percent Stagnation Temperature: Above**0m2 degree / KW Solar Irradiation for Water Temperature Rise below 3.0mj / m2 Coefficient of Average Heat Loss below 0.*0w / (m2 degree) Vacuum above 3.0 multipy ***2Pa (anti heat loose)
