TROUGH SOLAR THERMAL COLLECTOR

摘要

PROBLEM TO BE SOLVED: To provide a trough solar thermal collector capable of effectively using total direct solar radiation incident on a reflector and excellent in heat collection efficiency.SOLUTION: A trough solar thermal collector collecting sunlight reflected by a trough reflector in a heat collecting tube, includes a drive unit (such as rotary gears and chains) provided on a back surface of the reflector or in a lower portion of the reflector for driving the reflector to rotate so as to track sunlight.
