Solar Collector for Hot Water System

Features: 1) Integrate solar energy with building2) Decorate the house appearance3) Safe, healthy, energy saving and environmentally friendly4) Material:    a) Copper tube    b) Aluminum alloy    c) Other material as per customer's requirements5) 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 stablySpecifications: 1) Core: plate copper T22) Tube coating:     a) China made, black chrome        i) Absorptive: >92%        ii) Emissivity: <10%     b) China made, TXT:        i) Absorptive: >90%        ii) Emissivity: <30%     c) Imported, Tinox of Interpan:        i) Absorptive: >95%        ii) Emissivity: <5% 3) Over: Toughened glass Heat preservation: Yarn cotton (the soft yellow one) heat transition     4) Frame:    a) Material: aluminum alloy       Anti-erode5) Back  Material: beryllium with zinc plating6) Waterproof material motor-used PVC rubber7) Welding technology:    a) Ultrasonic wave welding between the copper belt and support tube    b) Gas welding is used between the support tube and collector tube8) Dimensions (L x W x T): 2,000 x 1,000 x 70mm
