Fins are extended surfaces that find use in variety of applications for heat transfer enhancement. Proper design and manufacturing of fin are essential for effective and efficient heat removal. Arrangement of fins, fin perforations, and surface property are some of the key parameters that impact heat transfer. Heat flow through fins depends on temperature distribution through it. Hence in the present experimental investigation, a comparison of temperature variations in in-line/staggered arrangement of fins, fin perforations, and fins of smooth/rough surface profile was studied. Higher heat dissipation was observed for three holes configuration compared to two holes configuration. Further, knurled fin surfaces offered better heat dissipation. In addition, staggered fin arrangement enhances heat transfer compared to in-line arrangement. Comparison was undertaken for both the cases of fins with/without heat generation.
