Page 6: Structure Of Solar Water Heater
SunMaxx Solar LLC 2. Structure of solar water heater Component description: HEAT PIPES: An evacuated-tube collector contains several individual glass tubes, each containing an aluminum fin and a heat pipe. The heat pipe transfers heat efficiently to the water in the tank. -
Page 7: Working Principle
SunMaxx Solar LLC The outer glass wall acts as glazing, creating a vacuum and protecting the coating against the elements. On the inner surface of tube ends, a silver-colored getter material is applied, which absorbs the remaining gases inside the tube’s hollow space. Deducting the absorption and surface reflection of the outer wall of the tube, the overall efficiency of the tube is over 92%. - Page 8 SunMaxx Solar LLC turns into a gas medium. The gas medium flows up to the top of the heat pipe and transfers the energy to the cold water in the tank, subsequently reverting back to a liquid medium and flowing down. As the process continues, the water in the tank will become the hot water.
