增透膜在槽式太阳能高温集热管产业化生产中的应用

摘要

高温太阳能集热管作为槽式太阳能热发电系统的核心部件，直接影响其发电效率。文章研究了采用溶胶-凝胶技术和提拉法在高温太阳能集热管的玻璃外管上镀制增透膜，大大地提高了集热管的集热效率；研制了年产15万支的集热管增透膜镀膜自动化生产线，产业化能力得到稳步提升。%The high temperature receiver tube is the core component of the parabolic trough solar power generation system, and has a direct bearing on the efficiency of the system. By using the sol-gel and dip coating method, anti-reflective coatings are prepared on the surface of the high temperature receiver tube. Thus the thermal efficiency of the high temperature receiver tube is increased. An automatic production line of anti-reflection coating for solar collector tubes is developed to enhance its industrialized production capacity.
