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。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。 This paper focuses on the theoretical discussion of the optical design of a hybrid concentrator system consisting of a Fresnel reflector and a mirror and the thermodynamic calculation of its collector. According to the specific structural design and theoretical derivation, the practical calculation formulas for designing such condensing heat collecting system are obtained, such as the shading calculation of plane mirror and Fresnel reflector, the calculation of the working fluid temperature in the collector tube and so on.
