Simulation and analysis of advanced solar dynamic system cell heat pipe receiver

In this paper, the study was to verify good thermal performance of heat pipe receiver. Cell heat pipe receiver of advanced solar dynamic system was numerically simulated. Accordingly, mathematical model was set up, numerical calculation method was offered, and calculation results were compared with those of NASA project. Analysis results show that heat pipe receiver which involves heat pipe owns the performance of perfect heat transfer and ideal identical temperature, the axial temperature difference of heat pipe is little, PCM canisters situated in different place of heat pipe can melt simultaneously and uniformly. At the same time, normal operation of wick ensures the uniformity of heat pipe circumference temperature, thus heat pipe receiver avoids phenomena of heat spot. In addition, heat pipe receiver has axial and radial performance of ideal identical temperature, all PCM canisters can freeze simultaneously at the end of eclipse, and freeze fully at last, so heat pipe receiver avoids heat ratcheting. Therefore, heat pipe receiver can improve the efficiency of system, avoid the phenomena of heat spot and thermal ratcheting.
