Heat pipe vacuum tube technical parameter Model: hp58/1800-20 l / 0.43 mm Outer tank material/thickness: sgcd/ 0.5mm Angle of collector: 25-85 ¡ã Rated pressure: 0.7mpa Heat pipe material: copper; 14/24 mm condenser diameter, 1800 mm pipe length. Insulation material and thinness: polyurethane foam, 50 mm Seal: silicon rubber polymer Manifold material: aluminum alloy Tank capacity: 100, 150, 180, 200, 250, 300 lite Advantages: 1. Adopts red copper channel, with great performance of heat exchange 2. Utilize copper heat pipes containing special medium liquid with low boiling point. 3. Work well in all climate, can be function well even in ambient temperature 4. Each heat pipe tube works independent and efficiently and easy to change if necessary. 5. No water flows inside the vacuum tube, no risk of freezing. Working principle: 1. Solar absorption: solar radiation is absorbed by the evacuated vacuum tubes and converted into heat. 2. Solar heat transfer: heat pipes conduct the heat from within the solar tube up to header. 3. Solar energy storage: water or water mix is circulated through the header, via intermittent pump cycling. Each time the water circulates through the header the temperatures is raised by 5-10oc / 9-18of. Throughout the day, the water in the storage tank is gradually heated.
