The Cooling Way Research of Solar Cells in Concentration

目的研究太阳能电池的冷却方式，提高太阳能电池在聚光条件下的工作效率.方法利用FLUNT大型分析软件模拟出聚光条件下电池板在不同冷却方式下的工作温度，并通过实验验证.结果有翅片轴流式冷却比不带翅片轴流式冷却温度低35-40℃，功率输出提高了15%；比带翅片的自然风冷却温度低50-60℃，功率输出提高了40%；比无翅片的自然风散热低100℃，输出功率提高了近70%.结论光伏电池在聚光条件下，带翅片有风扇的轴流式冷却方式效果明显，大幅度提高电池的输出功率，为聚光光伏发电的广泛应用提供了良好的基础.

To research the way of cooling system of solar cells in order to enhance the working efficiency of solar cells in concentration. The working temperature of different cooling modes of solar cells in concentration was simulated using FLUNT common software and the effective working way of cooling was discussed with experiment and simulation. The temperature of the cooling effect of having wings and having fans is comparatively approximately 35 - 40℃ lower than the temperature of that not having wings and having fans, the power output enhanced by 15 %, that is comparatively 50 - 60℃ lower than the temperature of that having wings natural wind cooling, the power output enhanced by 40 %, that is comparatively 100℃ lower than the temperature of that not having wings natural wind to radiate, the output enhanced by 70 %. The effect of the cooling of having wings and having fans of photovoltaic ceils in concentration is obvious, and this way can raise cell＇s output largely and provide a good foundation for the winder use of photovoltaic in concentration.
