Collector Solar Thermal Energy Device

In the modern period of rapid economic growth, energy shortage is serious, the new type of solar renewable green energy, has the character of the economy, clean environment, the advantages of large reserves, so it is by more and more attention. And solar power technology have been extensively studied and applied in various countries.Thermoelectric power generation technology is a way to directly convert heat into electricity technologies, a green energy. In power generation process, there is no noise, no emission, small size, light weight and so on. With the rapid development of thermoelectric materials and the improvement of thermoelectric performance. Thermoelectric technology has started apply from the military to the civilian and industrial applications.In this dissertation, thermal power generation device performance was studied using ANSYS software, optimization designing segmented thermoelectric unicouples with high efficiency in the temperature range (200-400℃).The main content as following:based on the theory of thermoelectric power generation. Simulation of various factors on the thermal properties of thermoelectric modules. An optimation designing model of segmented thermoelectric unicouple was made. The calvulation resule shows the conversion efficiency is over 10%,when the temperature reached 375℃.Aassembled a set of solar Collector thermoelectic power generation. Measured output power of thermoelectric power generation at different Solar radiation power, different number of thermoelectric module. Output power is about 10W when Solar radiation power is 880 W/m2. A DC-DC regulator circuit was Designed for battery charging by a switching regulator chip MAX669.Studying the solar energy selective basorbing theory, coating B92 selective basorbing paint on the solar collector plate to improve solar energy utilization.
