聚光光伏电池的效率受电池温度的影响很大。冷却装置存在的主要问题是散热不足和散热分布不均匀。本文提出了一种新型的多通道冷却流道，并对其进行了数值研究。考察了冷却剂类型、进口流量和通道尺寸对流形散热器冷却性能的影响。在中国深圳考察了四个节气对太阳辐照度的影响。结果表明，新型冷却歧管具有良好的冷却性能和温度分布均匀性。所研究的歧管的热阻也比文献报道的低。
The efficiency of concentrating photovoltaic cells (CPVs) is highly affected by the cell temperature. The main problems for the cooling devices are insufficient heat dissipation and uneven heat distribution. In this study, a novel cooling manifold with multi-channels for densely packed CPVs were proposed and numerical investigated. The effects of coolant type, inlet flow rate and channel dimensions on the cooling performance of the manifold heat sink device were examined. The influence of solar irradiance was also investigated at four solar terms in Shenzhen, China. The results show that great cooling performance and temperature distribution uniformity can be achieved by the novel cooling manifold. Thermal resistance of the studied manifold is also lower than those reported in the literature.
