Solar Vacuum Tube three-target solar vacuum tube with ISO9001-2000 ,CE certificate


Three target vacuum tube,the solar tube is made from high borosilicate 3.3glass and the structure of the 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 high vacuum.The surface of inner glass is sprayed with the selective absorbing painting lever to cover the outside surface of the inner tuber,the solar energy absorption rate can reach 96%.while the rate of thermal radiation below 4% . vacuum tube absorb the solar energy and then heats the water or liquid by heat conduction,the heat loss of liquid is very low through the high cacuum between inner glass tube and outside,its stagnation temperature is above 270 degree.it is widely used in solar water heater,solar collector,solar projects.
