The pipeline is made of all the red copper and conducted by heat transfer medium liquid. Water can't flow in vacuum tubes and operated. The manifold uses Aluminum alloy mould material of high strength with Air flow design. It is furnished in good style.
Can withstand high pressure when it works.
Module design, arbitrary combination, which can meet the demand of large water consumption.
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.
2) An electronic controoler measures the temperature of the solar collector and the water in the bottom of the storage tank. If the collector is hotter, meaning there is heat available. The controller supplies power to a circulation pump which pushes liquid which in circulation system circulating. The heat will transferred to storage tank via the liquid
