摘要
介绍槽式集热器的结构及其工作过程,对集热器进行热性能分析,研究已有集热器热力学模型,并对其进行优化,利用该模型计算各个部位的热损失大小以及集热器热效率,分析得出影响集热器热效率的主要因素,定量分析这些因素对集热器效率的影响趋势,并解释其原因。
The structure and working process of solar parabolic trough collectors was introduced firstly,then the heat performance was analysed.Based on the existed thermal theory model of heat collectors,a simplified model was put up.Heat loss and thermal efficiency for principal parts of heat collectors was calculated.This paper presented the chief factors effecting the heat efficiency,analysed the effection trend of these factors put on the collector,and interpreted these reasons.
