摘    要:在原有平板集热器的基础上研制了一种与建筑结合的太阳能集中供热热管系统,并对策略热管的传热机理进行了分析,提出正常工况下该热管的集总参数模型,给出了热管的倾角范围。文中给出了该集热系统的理论预测和实验结果对比。热管太阳能集热器的理论模型以Duffie 和Beckman理论(1980)为基础,修改后用于能量传输。该文还给出了该集热器和传统的太阳能集热器的对比试验结果。热管太阳能集热器的瞬时效率在早上低于传统的太阳能集热器的,而当热管达到工作温度时,前者高于后者。

关 键 词:集中供热  热管  太阳能  集热系统

Abstract:On the basis of flat plate collector, central solar heating system with heat pipes was studied and manufactured. Heat transfer mechanism of the two phased closed thermosyphon in this system was analysed. A new lumpedparameter model of heat pipe in normal working condition was developed. This paper presents a comparative study between theoretical model predictions and experimental results of heat pipe solar collector system. The results showed that the instantaneous efficiency of the heat pipe solar collector are lower than the conventional collector in the morning and higher as the heat pipes reach their operating temperatures.
Keywords:solar energy  heat pipe  lange  scale center heating system
