Working Principle

1) Vacuum tube is composed of inner and outer glass pipe, inspiratory layer, vacuum space, inspriatory membrane. The surface of inner and outer glass tube is plated with selective absorption layer. The layer absorb the solar energy and turn it into heat energy, aluminum fins pass the heat energy to the heat pipe, the liquid medium in the heat pipe is heated by the heat energy, then turns into the gas medium, the gas medium flows up to the top of the heat pipe (condenser) and transfer the energy to the copper manifold header heat pipe. At the same time the gas medium turns into the liquid when cooled, then flows down. Keep recycling.
