In renewable energy, solar energy has rich resources ,is friendly to the environment and safe, provides a new form of life for human beings, human society has entered a new era of energy saving and emission reduction. The way of use solar energy is varied, the parabolic trough concentrating collector belongs to the high-temperature heat collector, can be applied to the thermal power generation system, heating engineering, absorption refrigeration, desalination of sea water and so on . This paper introduced the parabolic trough concentrating all parts collector and its work principle, an energy balance model, model of solar radiation and heat loss model was established from the theory, analyzed the factors of the thermal efficiency and the effect of heat collecting efficiency loss from geometry, optical loss, heat loss angle. In the experimental study, tested the instantaneous average efficiency and the average collector efficiency, heat loss coefficient of the collector were determined, and observed the influences of dust and its azimuth on the collector performance.
