本文理論分析配合實驗印證，探討雙流式翅加檔板型太陽能空氣加熱器之收集器效率。雙流式裝置係以吸收板平行置放於空氣通道中而成。實驗結果印證了理論分析之正確性。理論分析及實驗結果皆顯示雙通道中最佳之空氣流通率比約為1（即最佳之空氣流率分率為0.5）。本研究亦探討檔板密度對收集器效率之影響。
The collector efficiency of double-flow solar air heaters with fins attached by baffles,
has been investigated experimentally and theoretically. The double-flow device was constructed
by inserting the absorbing plate into the air conduit to divide it into two channels, upper and
lower channels. Theoretical predictions are qualitative agreement with the experimental results.
Both the theoretical predictions and experimental results showed that the optimal fraction of airflow
rate in the flow channels is around the value of 0.5. The effect of baffle density on the collector
efficiency has been also presented and discussed.
