Abstract	The numerical analysis on convective heat transfer behavior and pressure drop characteristics of staggered circular tube bank fin heat exchanger with smooth fin and with interrupted half annular groove fin is carried out under the conditions of different tube rows (1,2,3,4,5), different fin spans (1.5mm, 2mm, 2.5mm) and different annular angles of interrupted half annular groove(30°,50°,70°), in addition, the velocity fields and the temperature fields of the structures are obtained. The results show that the ability of heat transfer could be enhanced by increasing tube rows, fin spans and annular angle of interrupted half annular groove in certain range, and the Nu number increases with the increase of Re number, whereas the resistance coefficient decreases with the increase of Re number in the heat exchangers both for the smooth fins and the interrupted half annular groove fins. The features of flow and heat transfer for heat exchanger with interrupted half annular groove fin are obtained by analysis of the formation, development and influence area of the vortices generated by interrupted half annular grooves.
