This paper introduces a new type of trough solar collector, focuses on the collector performance of the collector were studied and analyzed, and the thermal performance of the collector, and put forward the system optimization design. The results show that the new trough solar collector has a higher collector temperature and a higher heat collection efficiency. Under the drying conditions, the temperature of the collector can reach 190 ℃. Under the circulating conditions, 53 kg of collector medium Temperature up to 115 ℃, Instantaneous heat collection efficiency up to 36%.
