摘要：

A new design of recycling double-pass solar air collectors is proposed which incorporates a V-corrugated absorber to the conventional flat-plate device for increasing thermal efficiency. With the air flowing over and under the V-corrugated absorbing plate, the turbulence intensity as well as the convective heat-transfer coefficient are enhanced. The theoretical predictions and experimental results are presented graphically and show that both higher air mass flow rate and recycle ratio can lead to improvement of the collector performance as compared to that of the flat-plate solar air collectors.
