　　In the present paper, the heat transfer and pressure drop characteristics of small plain fin-and-tube heat exchanger with 4 tube rows in staggered arrangement are numerically studied.The focus is paid on the effect of edge region, which changes the distribution of fluid flow field.The results indicate that the tube arrangement of 6-6-6-6 is better than that of 6-5-6-5.
