Product Introduction
A parabolic trough solar collector is a highly efficient linear focusing solar thermal collection device, mainly composed of a reflector, high-temperature collector tubes, a support system, a tracking system, a transmission system, and a control system. The reflector rotates with the sunlight, and the trough collector directly converts solar energy into thermal energy. It has advantages such as mature technology, stable structure, and ease of control. It is widely used in various energy-saving fields, including industrial energy conservation, heating and cooling, seawater desalination, and oil extraction.
Main features
1） High collector operating temperature <300°C.
2）High photothermal conversion efficiency of 63.5%, compared to 40% for traditional solar energy.
3）Automated operation year-round, high performance stability, and good pressure resistance of the collector tubes.
4）Rapid temperature rise, 62.5 times linear focusing, raising temperature from room temperature to 1550°C within 15 minutes.
5）Pure green energy, derived from the sun, with low operating costs.
