Longpu 137mm Big Diameter Solar Vacuum Tube For Solar Cooker design

Longpu solar vacuum tube adopts interference solar absorption layer and unique three-target magnetron sputtering coating technology.Even at high temperatures of 400 degrees,the metal ions in the film will not be lost,and its strong endurance greatly prolongs its life.As the core component of solar water heater, the structure of Longpu solar vacuum tube is like an elongated heater, which consists of two borosilicate glass tubes with high chemical resistance and thermal shock resistance. There is a vacuum between the inner and outer layers. Spectral selective absorption coatings are coated on the surface of inner glass tubes by special technology to maximize the absorption of solar radiation energy. After irradiation by sunlight, the photon impacts the coating, and the solar energy is converted into heat energy. Then the water absorbs heat from the coating, so that the water temperature increases and the density decreases. Because the hot water moves upward, and the proportion of cold water drops, the hot water is always in the upper part. The temperature rise of hot water in vacuum tube is not related to the external temperature, but mainly depends on the light.
