摘　　要：以涡旋形流道太阳能空气集热器为研究对象,采用模拟方法,对5种涂层集热器的热性能和经济性进行分析。研究对象为黑镍涂层、黑铬涂层、氧化钴黑涂层、金属陶瓷薄膜涂层、氮氧化钛蓝膜涂层。涂层对集热器热性能影响比较小,对集热器投资回收期的影响比较明显。5种涂层集热器的单位空气得热量成本均低于常规电价。综合考虑集热器热性能、经济性,黑镍涂层是理想选择。Taking the solar air collector with vortex channel as the research object,the thermal performance and economy of five kinds of coated collectors are analyzed by simulation method.The research objects are black nickel coating,black chromium coating,cobalt oxide black coating,cermet thin film coating and titanium oxynitride blue film coating.The effect of the coating on the thermal performance of the collector is relatively small,and the influence on the investment recovery period of the collector is relatively obvious.The heat gain cost per unit air of five kinds of coated collectors is lower than the conventional electricity price.Considering the thermal performance and economy of the collector,the black nickel coating is the ideal choice.
