Abstract

The heat transport process of parabolic trough solar collector is analyzed, and the mathematical model of heat transport is established. The contrast made our calculation of model with result of experiment of LS-2 collector, through contrast test and correction, temperature of fluid outlet had a maximum error of 0.56%. meanwhile, some factors in account of influence fluid outlet temperature and thermal efficiency are analyzed, which including solar radiation intensity, fluid volume and the diameter of metal tube.There are three obvious relationships: with the increase of solar radiation intensity, outlet temperature increase continuously, but the change of thermal efficiency is insidious; with the increase of volume of fluid, outlet temperature keeps declining, efficiency continues to rise, but the increasement tend to be gentle; with the increase of the diameter of metal tube, both temperature and efficiency are decline, but the change of temperature are subtle.
