摘　　要：以平板微热管阵列为核心部件设计一种新型的太阳能空气集热器,对其热性能和阻力特性进行详实的实验研究。探讨不同季节对空气集热器集热效率的影响;空气流量对集热效率的影响;空气集热器的流动阻力特性。实验结果表明:夏季稳定运行状态下集热器的集热效率可达73%,流动阻力小于25 Pa。A novel type of solar air collector by using fiat heat pipe arrays was designed. The relationship between the heat collecting performance and the air flow rate at different seasons was investigated experimentally. The flow resistance of the solar collector was also studied. The experimental results showed that the heat collecting efficiency of the collector is up to 73%, and the flow resistance is less than 25 Pa.
