Solar air heaters, because of its simply structure, flexible and convenient characteristic, could be widely used for winter heating of the Non-central heating building. However, the existing heaters are either too inefficient or too costly, which seriously limits their practical application. Based on this, this study proposed an aluminum honeycomb solar air heater, which used aluminum honeycomb for radiation absorption and heat transfer. In order to explore and optimize the efficiency of aluminum honeycomb solar air heater, in this research, experimental and mathematical research have been down. The results show that: aluminum honeycomb heater have higher efficiency; In mechanical ventilation, when the aluminum honeycomb parameters for the diameter * depth is 6*10mm, heater efficiency is the best; The efficiency curve of the aluminum honeycomb solar air heater is increasing with the increase of wind speed, which is basically stable at 5m/s, with 78% efficiency.
