Vacuume tube pressurized solar collecor

Vacuum tube for solar water heater Introduction:
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 94.5percent 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 200 degrees. It is widely used in solar water heater, solar collecotor, solar projects.
