Some important results of experimental studies on perforated fins with different configurations having equal weight are presented. This study was performed by considering effect of both conduction and mixed convection for extended surfaces with different configurations. An experimental setup was designed and fabricated for the purpose. A uniform heat generation and equal weight of fins are maintained for the comparison. Different types of fin configurations viz., solid, hollow, solid pin fin

... h a single perforation solid pin fin with four perforations and solid fin with knurling, having equal weight are considered for the study. A comparative study has been done on the performance of fins used in various applications. Further an effect heat transfer parameters on perforated fin were discussed in detail.
