This article examines the efficiency of heat sinks of solar air collectors (SAC) using metal shavings as an absorber. The main attention is paid to the different types of metal shavings and their natural colors that are formed during metal processing. The results of experiments to determine the heating temperature of metal shavings of different colors, grouped into light and dark shades, are presented. The studies were carried out under real conditions in the heliostat section of a large solar furnace. Experimental data showed that dark shades of chips (dark blue, slate and violet) have a higher heating temperature compared to light shades (pale yellow, light yellow and white). The article also discusses methods for measuring and calculating temperature indicators of chips, including colorimetric and optical methods. The results obtained indicate a significant influence of the color of metal shavings on the thermal efficiency of the SAC. The dependences of the influence of air flow on the temperature of chips of various colors are given and conclusions are drawn about the influence of these factors on the efficiency of SAC.
