solar collector Product Description The split and presure solar water heater composed by heat pipe vacuum tube solar collector, pressure storage tank, controller, working station Features: 1) The pipeline is made of red copper and conducted by heat transfer medium liquid.Water can't flow in the Features: The heat pipe sreies solar collector are always connected with existing heating supply device.the selective coating on the inner cover or the evacuated tubes converts solar energy into heat energy and transfers heat to the heat pipes by Aluminum fins.the liquid in the heat pipe changes into vapour which rises to the codenser.The heat conducts to the heat transfer liquid(anti-freezing liquid or water)via a copper pipe. this transference of heat in the liquid creates a cintinuous circulation as long as the collector is heated by the sun 1) Reliable and efficient twin-glass solar tubes; 2) Copper heat pipes for rapid heat transfer; 3) Easy plug-in installation; 4) Free maintenance; 5) Suitable for mains pressure water (up to 8 bar/116psi); 6) Corrosion resistant silver brazed copper header; 7) Aluminum frame; 8) Powder coated (black, brown or silver) aluminum casing; 9) Stable solar conversion during the day; 10) The perfect solar collector for domestic solar water heater systems; 11) Ideal for commercial solar water heating applications. How it works: 1) The operation of the solar collector is very simple. 2) Solar absorption: Solar radiation is absorbed by the solar tubes and converted into heat. 3) Solar heat transfer: Heat pipes conduct the heat from within the solar tube up to the header pipe 4) Solar energy storage: Water is circulated through the header, via intermittent pump cycling. Each time the water circulates through the header, the temperatures is raised by 5-10oC. Throughout the day, the water in the tank is gradually heated.
