Description



Product Description


Parabolic trough solar high-temperature collector is an efficient linear focusing solar heat collector, which is mainly composed of a reflector, a high-temperature collector tube, a bracket system, a tracking system, a transmission system and a control system. It has mature technology, stable structure, and easy control and other advantages. The reflector rotates with sunlight and can directly convert solar energy into heat energy. It is widely used in solar thermal power generation, industrial energy saving, heating and cooling, seawater desalination, drying, coal-fired boiler replacement, oil extraction and other energy-saving fields.

Solar high temperature collector tube
The high-temperature collector tube is the core component of the trough solar collector. It is mainly composed of a metal inner tube coated with a selective absorption film and a glass outer tube coated with an anti-reflection film. Vacuum is drawn between the glass outer tube and the metal inner tube to reduce heat loss and prevent oxidation of the selective absorption coating.




Parameters of high temperature collector tube:
◆ Collector length: 2000mm/4060mm
◆ Outer diameter of glass tube: 95mm/125mm
◆ Outer diameter of metal pipe: 40mm/70mm
◆ High transmittance: The outer cover glass tube is coated with AR antireflection and antireflection coating, and the sunlight transmittance reaches more than 96%
◆ High absorption rate: α ≥ 95.5%
◆ High vacuum degree: ≤ 10-3mbar, high temperature exhaust process at 460 ℃
◆ low heat loss:<117 W/m(350 ℃), <111 W/m(300 ℃), <69 W/m(250 ℃)
◆ Corrosion resistance: The inner tube is made of DIN1.4541 steel, which has the advantages of corrosion resistance and high pressure resistance.
◆ Service life: ≥ 20 years
◆ Operating temperature: the heat conducting medium can reach 380 ℃
◆ Application ambient temperature:-40 ℃
