摘要
通过对CPC型热管式集热器进行的传热分析和相关的试验,给出了内聚光CPC热管集热器的总热损系数、效率的计算方法,并测定了它的效率曲线,试验结果与理论计算值符合很好。文中所分析的是CPC型热管式真空集热器的通用模型,因此,对于各种形状CPC型热管式真空集热器所推导出的计算式都是适用的,这对于改进集热器设计和预示集热器性能都具有一定的参考价值。
Based on heat transfer analysis and relative experiment of CPC heat pipe evacuated tubular collectors. Calculating methods for determining the overall heat loss coefficient and collector efficiency were presented. Instantaneous efficiency curve were also tested. Experimental results coincide with theoretical calculations quite well. Model analyzed was normal, therefore, formula deducted can be applied to all kinds of CPC heat pipe evacuated tube collectors. It's worthy for improving collector design and indicating the performance of collector.
