摘　　要：为提升太阳能空气集热器的集热性能,在传统集热器的基础上填加吸热材料,创建双重吸热式空气集热器,并通过实验进行了对比分析.结果表明:双重吸热式集热器在进出口温差和集热效率方面比传统型集热器有所提升,同时填加的吸热材料设置于集热板下部时,具有较优的集热效果.In order to improve the performance of solar air collector,this article established a double-endothermic air collector by adding endothermic material based on conventional collectors.The results show that the double-endothermic collector is better than the conventional collector in the aspect of the temperature difference between the inlet and outlet,and the collection efficiency is better when the endothermic material is put under the collecting plate.
