In this study, the effect of incorporating turbulators and external mirrors into a newly single pass Solar Air Heater (SAH) was investigated experimentally. Aluminium cans were stacked over the absorber plate and used as turbulators to enhance the heater efficiency. The external mirrors are utilized to improve energy input to the SAH. The effect of external bottom and top mirrors on the SAH performance is studied. Three models of absorbing plates had been tested after designing them. The first one is a flat plate without cans (turbulators), the second one is a flat plate with cans in aligned arrangement configuration and the third one is flat plate with cans in staggered arrangement configuration. A comparison between the efficiency of the modified SAHs air heaters with and without reflectors and the conventional SAH were carried out. In addition, guide vanes were attached to the inlet of a heater for ensuring better distribution of air above the absorber surface. Typical ranges of air Mass Flow Rate (MFR) are employed from 0.02 to 0.05 kg/s. Results showed that the maximum daily efficiency of the proposed SAHs was about73.4% at 0.05 kg/s for staggered heater with external reflectors and guide vanes.

在这项研究中，实验研究了将湍流器和外后视镜集成到新的单程太阳能空气加热器（SAH）中的效果。铝罐堆叠在吸收板上，并用作湍流器以提高加热器效率。外部镜用于改善输入到SAH的能量。研究了外部底镜和顶镜对SAH性能的影响。设计了三种吸收板模型后，对其进行了测试。第一个是不具有罐（湍流器）的平板，第二个是具有对齐结构的罐的平板，而第三个是具有交错结构的罐的平板。进行了带有和不带有反射器的改进型SAH空气加热器与常规SAH的效率比较。此外，导向叶片连接到加热器的入口，以确保空气更好地分布在吸收器表面上方。空气质量流量（MFR）的典型范围是0.02至0.05 kg / s。结果表明，对于带有外部反射器和导向叶片的交错加热器，建议的SAH的最大日效率在0.05 kg / s时约为73.4％。
