摘　　要：研制了可转动的叶片式吸热板集热器,该集热器与传统的太阳能集热器不同,集热器的叶片吸热板可转动,实现了吸热板跟踪太阳能运行,最大限度吸收太阳辐射.吸热板背面涂以热反射涂层,夏季叶片翻转180°,反射红外辐射隔热降温.分析了影响太阳空气集热器瞬时集热效率的各种因素,并对其热性能进行了试验.结果表明,叶片式吸热板集热器在强迫对流循环试验条件下最佳风机风量为120 m3.h-1.In this study,solar air collector with leave structure absorber was designed.The absorber,different from the traditional structure,can turn track the sun,and solar radiation.Its back,coated with heat reflecting paint,can turn around 180° in summer to reflect solar radiation.The factors affecting heat collection efficiency were analyzed and experimental study on thermal performance of the solar air collector were conducted.The results show that the optimum parameters of air flow rate in forced convection is 120 m3·h-1.
