This research is to incorporate three efficient ways that will increase the perfor-mance of baffled heat exchangers. The 1st technique is represented by baffle per-forating to create pores through which secondary streams pass in order to reduce main stream pressure on the flow areas. A 2nd technique represented in redesign-ing the baffle structure by replacing its square edge with the arched edge in or-der to increase the X-velocity to facilitate the flow towards the outlet and reduce the Y-velocity to reduce the values of fluid friction with the solid areas. Finally, a 3rd way was demonstrated by using the inclined baffle model. Reinforcement of the baffle structure allowed for enhanced vortices, increased thermal gradients, and thus a reinforced thermodynamic structure over the entire heat exchanger
