摘　　要：该研究提出了一种带内插管的真空管空气集热器,利用传热理论,对该集热器的热工性能进行数学建模和模拟分析。模拟结果显示:这种空气集热器可以根据需要获得一定温度的热空气。速度越大,效率就越高,但出口温度相对较低。因此,在实际应用中可根据实际需要控制空气流速获得相应温度的热介质。这些热介质在冬天的时候可用于建筑采暖,在夏天的时候可以作为空调除湿部分的热源及干燥农作物和水果等,大大增强了太阳能真空管空气集热器的地区适应性和季节适应性。This paper presents a vacuum tube air collector with intubation,using the theoryof heat transfer and using mathematical modeling and simulation analysis to analysis the thermal performance of the collector.The simulation results shows that：the air collector can be according to the need to get a temperature of hot air.The higher the speed,the greater the efficiency,but the exit temperature is relatively low.In practice,therefore,according to actual needs to control the air flow speed to obtain heat medium of corresponding temperature.The heat medium can be used in building heating in the winter,and in the summer it can be used as the heat source of air conditioning dehumidification part and dry crops and fruits and so on.It greatly enhances the solar vacuum tube air collector＆#39;s area and season adaptability.
