中文摘要：

提出了一种新型中央接收式太阳能高温集热系统,介绍了系统的运行原理,分析了系统的热效率影响因素。这个新型的太阳能高温集热系统具有如下特点：可将多个光漏斗和偏光器组成一个太阳能聚光器阵列,每个聚光器都能将低能流密度的太阳光束会聚成高能流密度的平行光束,并由偏光器传送到中央接收器,于是中央接收器可获得很高的太阳光照射能流,转化为热能后将产生很高的温度,从而实现太阳光高温聚能。本系统的中央接收器无需建在高塔上,节省了建设费用,而且所有光漏斗跟踪太阳的方式相同,控制策略简单,定向偏光器的出光方向设定后可以固定不变,因而使整个系统结构简单,技术上易于实现。

英文摘要：

A new type of the centralized high-temperature solar energy collecting system is developed. The operating principle is introduced.The factors that influence the efficiency of the system are analyzed.This new type of the centralized high-temperature solar energy collecting system has a distinct characteristic.Many light funnels and light deflectors form an array in a solar energy concentrator.Every concentrator can turn low-density solar energy into a parallel beam with high density.By a light deflector,the light beam is transmitted to a central receiver.Then the central receiver gains a high-density energy flow and turns it into high-temperature thermal energy.The receiver of this system does not need a high tower to support it.Therefore,it will save a lot of fabrication cost.Moreover,all the light funnels have the same tracking system,which makes the control strategy simpler and easier than that in a solar tower.
