Product Name: Solar Energy Collectors Place of Origin: China Features: 1) Integrate solar energy with building 2) Decorate the house appearance 3) Safe, healthy, energy saving and environmentally friendly 4) Material: a) Copper tube b) Aluminum alloy c) Other material as per customer's requirements 5) Types: a) Glass vacuum tube collectors: i) High efficiency ii) Can supply hot water at any time iii) Compare with flat plate collector, it hides some potential safety hazard, the possibility of bursting of a tube b) Heatpipe collector: i) High efficiency ii) Operating safe and stable iii) Water quality requirement iv) Higher cost c) U-tube collector: i) Better heat conduction (a little lower than all glass vacuum tube collector) ii) No danger hidden iii) The system is not all optimized iv) Higher cost d) Flat plate collector: i) Long service life ii) Fewer malfunctions iii) Less danger hidden iv) Low cost v) With frost free design, resolves the frozen problem, therefore can be used even in winter vi) No requirement of degree of vacuum vii) Higher efficient conduction viii) Stable quality ix) Water or working fluid goes through the mental collector tube without touch of glass capping plate, which avoids bursting of the tube caused by shock cooling and heating that can make the system paralysed x) Can be installed gapless, thus has functions of the traditional roof (keeping warm, insulating, obscuring, water proofing) while providing hot water. Can replace part of or the whole traditional roof xi) The length, width or dimension can suit different building roof or wall xii) Can endure high pressure, operating safely and stably |
