摘　　要：提出采用冲孔波纹板的渗透型空气集热器，并对下进风、上出风和上进风、下出风两种运行模式建立传热数学模型，通过实验值与模拟值的对比，验证数学模型的准确性。以集热器的进出口温差、集热效率为评价指标，模拟研究集热器的结构参数、运行参数对集热器性能的影响。研究结果表明在两种模式下，集热板开孔率、集热板高度和空气流速对集热器性能影响较为明显，集热板开孔率最佳范围为8％-16％，集热板最佳高度为1．6～2．8m，空气流速宜选择0．40-0．60m／s。The transpired air collector with punching corrugated model of two operating modes （under into wind, on out wind; plate was proposed and the heat transfer mathematical motivated wind down out wind） was established. The accuracy of mathematical model was verified by comparing experimental result with simulation value. The air temperature difference between input and outlet and thermal efficiency were chosen as evaluation index to simulate the effect of structure parameter and operation parameter of collector on the performance of collector. The simulation results show that the effect of plate opening rate, plate height and air flow rate on the performance of collector in two operating modes is more obvious. And the optimal values of plate opening rate, plate height and air flow rate are 8%-16%, 1.6-2.8 m and 0.40-0.60 m/s, respectively.
