Optimized design of collector topology for photovoltaic systems
Aiming at the problems of photovoltaic system collector structure optimization,the variable density method was used,and the lowest average temperature in the design domain was used as the objective function,the topology optimization on collector was designed in the fluid volume fraction of 50％and with different Reynolds number(Re).The results show that Re is greater,the design of the domain of the branched flow channel is less.Numerical simulation of the obtained topology under the same conditions shows that the temperature distribution under different Re does not differ much,and the temperature distribution is more uniform,which achieving the effect of reducing the temperature of the PV panel.
