摘要

构建一种全等多截面非对称复合抛物聚光器（MA-CPC）,并对其结构特征、聚光特性及经济可行性展开探索。基于全等聚光平面,并耦合3D打印制造技术、平面聚光镜和太阳能真空管搭建太阳能MA-CPC实验装置,采用激光实验对MA-CPC的几何结构可靠性进行验证。继而分析和探讨MA-CPC系统的光学效率、太阳辐射收集、聚光均匀性和经济效益。研究发现太阳能MA-CPC可实现秋冬季节对辐射能的较高收集,且聚集到吸收体表面的太阳辐射较同规格N-CPC具有更好的均匀性,研究结果还表明所构建的太阳能MA-CPC在相同投资下年辐射能的产出较N-CPC优势明显,具有潜在的工程应用前景。

Abstract

Solar compound parabolic concentrator （CPC） has the characteristics of no need for real-time tracking, adjustable acceptance half-angle, and simultaneous receiving of beam and diffuse radiation, however, conventional CPC concentrating surfaces are not easy to produce, transport, install, and maintain. Therefore, in this research, a congruent multi-section asymmetric CPC （MA-CPC） is novelty constructed and its structural characteristics, concentrating properties and economic feasibility are explored. Based on the congruent concentrating plane technology, and coupled with 3D printing manufacturing technology, plane concentrating mirrors and solar vacuum tubes to construct a solar MA-CPC experimental setup, the reliability of the concentrating characteristics of MA-CPC is verified using laser experiments. Following this, the optical efficiency, solar radiation collection, concentrating uniformity and economic efficiency characteristics of the MA-CPC system are analyzed and discussed. It is found that solar MA-CPC can achieve higher collection of radiant energy in the autumn and winter seasons, and the solar radiation gathered to the absorber surface has better uniformity than the same size N-CPC. The results also show that the constructed solar MA-CPC has a significant advantage over N-CPC in terms of annual radiant energy output for the same investment, and has potential engineering applications.
