在世界能源供应日益紧张的今天,太阳能的研究和应用已越来越为各国所重视。澳大利亚近年来也在这方面进行了不少工作,目前正在研制的一种太阳能集热器,热效率较高,很有特色。集热器是利用太阳能的关键装备。目前技术比较成熟、已开始进入商业生产阶段的集热器大都是平板型的。这是一块表层上涂了黑漆的金属薄板或板网,太阳能经它吸收后转换为热能。这种集热器制作简便,成本较廉,但其最大缺点是热效率低。也就是说,在它吸收太阳能的过程中,有相当一大部分能
In today’s increasingly tense energy supply in the world, the research and application of solar energy have become more and more important for all countries. In recent years, Australia has also done a lot of work in this respect. Currently, it is developing a solar thermal collector with high thermal efficiency and unique features. Collector is the use of solar energy key equipment. The current technology is relatively mature, has begun to enter the commercial production stage mostly flat-type collector. This is a sheet of metal or metal mesh painted with black paint on the surface, which is converted into heat energy by its absorption. This collector is easy to manufacture, less expensive, but its biggest drawback is the low thermal efficiency. In other words, it absorbs a lot of solar energy
