Effect of staggered perforated plate header on flow and heat transfer of plate - fin heat exchanger
錯排孔板封頭對板翅式換熱器流動與換熱的影響 -
When the punched baffle is proper in length, the small holes are in staggered arrangement and the punched ratio gradually increases from the central axis to the boundary along the baffle length, the performance of flow distribution in the plate - fin heat exchanger is effectively improved by the optimum design of header configuration
從實驗對比分析中得出，當擋板小孔呈錯排分佈、開孔率沿擋板的中軸線向兩側逐漸增加、且總開孔率達到50 %左右的時候，在相同的入口條件下，不均勻系數由原始封頭的1 . 210降至0 . 209 ，最大流速與最小流速之比由23 . 163降至1 . 756 。
