The heat sinks thermal performance with four aluminum fin configurations set under mixed convection settings at three voltage values 100, 150, and 200 V, was examined. Six fins are part of a heat sink. The flat fin is the first type (case1), the corrugated fin was the second (case2), the third one was a corrugated fin with rectangular perforations with its rib (case3), and the last one was corrugated with triangle perforations with its rib (case 4). The surface area of all studied cases is equal. The third and fourth studied cases are new proposed configurations by this work. The air velocity was 1.5 m/s. The temperature distribution along the fin surface was measured for each case study. The theoretical study was held on each studied case using a fluent package (ANSYS18 software). The absolute deviation between the experimental and numerical study for each studied case temperature distribution is 2.95% for case 1, 3.37% for case 2, 1.41% for case3 and, and 1.2% for case 4 at 160 W supplied power heater. Cases (3 and 4) will enhance the heat transfer coefficient compared to the flat fin case 11) which was 4.16% and 4.27% respectively. The fin perforations with its ribs case (3 and 4) decrease the material cost and heat sink weight to 7.7% and 8.3% respectively. Also, the required space to locate the heat sink is minimized |
