摘　　要：加装扰流板的蛇形太阳能空气集热器是平板式太阳能空气集热器的常见改进形式。文章对上风道、双风道、下风道蛇形太阳能空气集热器的集热效率和热量损失进行模拟分析。分析结果表明:3种太阳能空气集热器的集热效率随着测试时间的变化均呈现出先升高后降低的变化趋势;上风道、双风道、下风道蛇形太阳能空气集热器的平均集热效率分别为57.53%,64.69%,65.24%,热量损失分别为429.26,323.97,317.01 W。Snake shaped solar air collectors equipped with spoilers were the common improvement for flat-panel solar air collectors.Through the simulation analysis of the three snake shaped solar collectors of the upper plenum,double plenum and lower leeway,it is obtained that the collection efficiency of the three collectors increases first and then decreases with time.The average efficiency of the snake shaped solar air collectors with three structures of the upper plenum,double plenumand lower leeway was 57.53%,64.69,65.24%,respectively.The heat loss was 429.26,323.97,317.01 W.
