在槽式太阳能集热装置中,为了减少吸热管与外界的对流损失,一般采用真空集热管。为此,设计出一种新型腔体(黑体)式集热管,以质优价廉的优势适应中温(100~250℃)的应用场合。建立槽式太阳能聚光三维模型,分析了聚光器的焦距、聚光器跟踪误差角与腔体开口宽度之间的关系,对腔体结构进行了优化。并基于 TracePro 软件,对集热管进行聚光性能模拟。结果表明,在跟踪误差存在的情况下,聚光器聚光效率达到80%,验证了实际工作中的可能性。

In order to reduce the convection loss between the solar collector tube and the environ-ment,a vacuum collector is usually used in trough solar collector.A new cavity (black cavity)collec-tor has been designed with its high quality and low price adapting medium temperature (100~250 ℃) applications.A three dimensional model of solar trough collector has been built.The focal length of the condenser has been discussed,the relationship between light concentrator tracking error angle and the cavity opening width has been analyzed,the cavity has also been optimized.The working situa-tion of collector tube has been simulated by soft-ware TracePro.The results show that nearly 80%of the light can be reflected to collector tube in cavity,and the possibility in practical work has been proved.
