集光镜

For concrete construction design, practical calculation formule were dedused theoretically. Light shielding effects of Fresnel reflector and heliostate were examined and the temperature of working fluid in receiver pipe was calculated.

根据具体的结构设计和理论推导，得到了为设计这类聚光集热系统实际可用的计算公式，如平面镜和菲涅耳反射镜的遮荫计算，集热管中工质温度的计算等。

In this paper a theoretical discussion of the optical design and the thermal performance of receiver pipe of the hibrid type concentrating collector was given. This collector consists of Fresnel reflector and heliostats.

本文着重从理论上讨论由菲涅耳反射镜和平面镜组成的混合式聚光集热器系统的光学设计及其集热管的热力学计算。
