复合抛物面型集热器吸收体温度分布的试验研究

Experimental analysis of temperature distributions on the CPC's absorber

针对具有平面吸收体的复合抛物面型集热器(CPC)建立了试验装置,对此CPC太阳集热器吸收体平面上的光、热性能进行了试验研究。结果表明,所设计的CPC集热器具有良好的聚光能力。分析了吸收体平面上的温度数值分布及影响因素并在三维空间内用射线跟踪法进行了模拟,从而为CPC集热器吸收体温度的进一步研究提供参考。

An experimental equipment of a compound parabolic concentrator with a flat absorber was set up.The experimental investigation of the flat absorber's optical performance and thermal performance has been performed.It has been demonstrated experimentally that the CPC which was designed has high optical efficiencies.The flat absorber's numerical temperature distributions as well as the infective factors were analyzed.These were simulated by ray tracing in three-dimensional space.Analyzing results would be helpful for further study of temperature distributions on the CPC's absorber.
