Abstract: This paper focuses on enhancing the convective heat transfer rate with help of fins and variations by providing perforations. Experiment is conducted for both natural convection and forced convection for constant base plate at temperatures. Forced convection is carried at air velocity of 3.1m/s just before fins. Fins are rectangular with square cross-section. Experimental trails are conducted for inline and staggered fin plates. The experiment is conducted in three variations. First variation is solid fins without perforation. Second variation is fins with one perforation at 25 mm from base plate. The third variation is fins with two perforations separated 50 mm from center to center. These experiment trails are carried under an experimental setup which is designed for fin testing purpose for different alignment of fins
