This paper presented the results of a solar air collector with internal crimped fins. It consists of a flat plate collectors with seven internal crimped fins and has the total collection surface area of 2m2. The investigation results indicate that the introduction of internal crimped fins can strengthen the convective heat transfer process and lessen the radiation heat loss, which contributes to efficiency improvement. In case the optimum number of for this study was seven crimped fins, The result of the air mass flow rate should be controlled in a range of 0.025–0.027kg/s. The influence of internal crimped fins number, ratio between leght wing and fin pitch, as well as the air mass flow rate on the collector performance presented in this paper. The operating parameters such as the surrounding temperature, solar radiation intensity have significant influence on the temperature rise but have little influence on collector efficiency, which indicates that this kind of solar air collector could be applied in a wide range of geographical latitude.
