Paper Title:
The Simulation of Heat Pipe Evaporator in Concentration Solar Cell
  Abstract

Considering the problem of the concentrating solar cell efficiency restricted by the temperature. The closed two-phase thermosyphon was used to dissipation heat in concentrating solar cell at high heat flux, which adopted water as the working fluid. The temperature distribution of evaporator had significant effect on solar cell performance and heat pipe efficiency. A numerical simulation model of evaporator was established by FLUENT. During the computing process, the heat flux, filling ratio of liquid and saturation temperature were taken into account. It was found that the maximum temperature of evaporator was less than 85°C, when the solar cell operated in 140 to 180 suns, in the conditions of evaporator size (Length×Width×Height, 100×100×30 mm), the optimum charging ratio of liquid is between 27%~30%. The smaller saturation temperature would bring the better heat transfer characters.
