Working Principle of vacuum tube type solar water heater

Solar water heater is all glass vacuum tube, heat preservation water tank, bracket three parts. The core component is the all-glass vacuum collector tube, which consists of two concentric circle of the special hard glass tube borosilicate composition, and the inner wall of glass vacuum coating process by magnetron sputtering coating, the coating on the sun Selective absorption of light, its absorption ratio ≥ 0.92, emission ratio ≤ 0.09 (80 degree), with a high absorption rate and low emissivity. Vacuum tube to absorb solar radiation into heat energy, the use of water density than cold water, cold water sink, hot water up the characteristics of the formation of cold water in the vacuum tube from top to bottom, bottom of the natural water cycle The temperature of the entire water tank to gradually increase, reach a certain temperature.
