AI Technical Summary
Technical Problem
Traditional trough concentrators have generally low thermal conductivity of the working fluid and lack reflector protection, which leads to reduced heat transfer efficiency and reflector damage in extreme weather conditions.
Method used
Nanofluids are used as the heat transfer medium inside the heat collection tube, and the reflector is protected by an arc-shaped plate structure driven by a servo motor. The reflector status is monitored by a pressure sensor to ensure the light-gathering effect.
Benefits of technology
This improves heat transfer efficiency, prevents damage to the reflector in extreme weather conditions, and ensures the stability and efficiency of the concentrator.
