An experimental investigation has been carried out to study the thermo-hydraulic performance of a solar air heater with staggered multiple C-shape perforated and non-perforated finned absorber plate. The experiments were conducted with a relevant range of flow parameters as Reynolds number from 3000 to 27000 and geometric parameters such as relative pitch to gap ratio from 3.4 to 3.8, relative height ratio 0.3 to 0.7 and relative perforated ratio 1.5 to 3, with focus on their effects on the maximum heat transfer enhancement. The higher thermal performance was achieved at relative pitch to gap ratio, 3.8, relative height ratio, 0.6 and relative perforated ratio, 3. The thermal performance and friction factor for C- shape finned absorber plate without perforated hole for relative pitch to gap ratio, 3.8 and relative height ratio, 0.6 were 2.61 and 5.93 times more than the smooth plate absorber plate, respectively. The perforated fin with the same relative ratios gives the thermal performance and friction factor by 2.67 and 5.34 times higher than the smooth absorber plate solar air heater, respectively. The correlations were developed to match the experimental Nu and f with the deviations of ±9.63% and ±9.44% for non-perforated fin and ±9.53% and ±8.73%for perforated fin respectively.

已经进行了实验研究以研究具有交错的多个C形穿孔和非穿孔翅片吸收板的太阳能空气加热器的热工液压性能。实验的相关参数范围是雷诺数从3000到27000，几何参数例如相对节距与间隙比为3.4至3.8，相对高度比为0.3至0.7和相对穿孔比为1.5至3，重点是它们对最大传热增强的影响。在相对节距与间隙比为3.8，相对高度比为0.6和相对穿孔比为3时，可获得更高的热性能。对于不具有相对节距与间隙比的C型翅片减振器板，没有穿孔的热性能和摩擦系数，相对高度比率3.8和0.6分别为2.61和5。分别是光滑板吸收板的93倍。相对比率相同的多孔散热片的热性能和摩擦系数分别比光滑吸收板式太阳能空气加热器高2.67倍和5.34倍。建立了相关性以匹配实验Nu和f，无孔鳍的偏差分别为±9.63％和±9.44％，而有孔鳍的偏差分别为±9.53％和±8.73％。
