Abstract: According to testing conditions, heat transfer calculations and analyses for the rectangular fin, small fin, heat pipe radiator and other types of cooling systems are carried out in this paper.Because of the high energy flow density and nonuniform heat transfer characters, the optimal design of the cooling system's structure is found out.Comparing the obtained simulation results, the cooling effect of the optimized structure is more obvious, the heat pipe can make the temperature distribution more uniform, and small fin enhances heat transfer comparatively well.The research results will reduce the cost of photovoltaic concentrator system, and improve its efficiency of power generation and life.
Keywords: concentrating PV system; heat pipe radiator; nonuniform heat transfer; numerical simulation
