摘要

Solar absorber is a device to collect the solar radiation and convert it into heat energy for the subsequent applications. This study studied the radiation heat flux absorbed in a cavity solar receiver by the ray tracing method for a dish concentrating solar power system. The resulting heat flux on the absorber was used to calculate the temperature distributions of the receiver. Cavity receivers with cylindrical or square shapes of cavities were compared by numerical simulations. By varying the cavity depth and focal position of the receiver, the radiation heat flux and temperature distributions were discussed. A circulating fluid channel was used as the heat output device of the receiver. According to the temperature limit of the receiver material, design of the setup of the CSP system was proposed with the specified output temperature for the fluid channel. Under the material's temperature limit, the output temperature of the fluid will be restrained within a certain maximum. This output temperature maximum was found to decrease with the increase of concentration factor.
