U.S. Dick solar glass vacuum tube, the use of nano-molecular techniques, the absorption ratio greatly strengthened, heat set *8% increase, the water temperature higher, the same light, not the same efficiency. Using U.S. technology and processes, strict control of cleaning the exhaust from each process, so that the high-vacuum tube laminated to ***3Pa, radiant heat loss is smaller. Carbon-carbon coating for a unique role in the stability of coating layer than the traditional AL-N/AL stronger, more powerful anti-aging properties, film properties remain longer. Strict selection of high vacuum tubes of borosilicate glass 3.3 materials processing, so that the vacuum tube has a thermal expansion coefficient, strength characteristics, the following hail-resistant *5mm positive impact. Advanced: Graded multi-layer magnetron sputtering of aluminum - nitrogen / aluminum coating solar selective absorption coating new technology to further improve the efficiency of the vacuum tube collector. Timber about: Tube material selection consistent with QB/T******9 (idt) ISO********8 standard borosilicate glass tube 3.3 manufacturing, its high transparency and good resistance to thermal shock, high optical stability. Quality assurance: In strict accordance with GB/T*********7 national standards, meticulous organization, strict management, starting from raw material purchase, until the final product out of libraries, all staff work together strictly to the Road, product quality, eliminate substandard products leave the factory. Heat pipe solar vacuum glass set performance parameters: Collector efficiency: vacuum magnetron sputtering aluminum nitride by selective absorption of aluminum coating, the solar spectrum absorption ratio ≧ 0.*3, thermal emissivity ≦ 6%, heat loss, thermal insulation effect is good. Weather is good: better thermal efficiency throughout the year, and hail resistance diameter *5mm front shocks, pressure capacity: 0.6Mpa. Long life: *5 years of life to ensure that the vacuum tube.
