摘要: Abstract This paper investigates the effect of perforation shape or geometry on heat transfer perforated fins. The type exchanger used is sink with fins under forced convection to determine performance for each between circular, rectangular, triangular and also non-perforated experimental result compared coefficient clarify best plate sink. fluid properties normally were studied experimentally numerically using CFD. difference numerical results was reported be about 8% 9% temperature distributions when power supplied are 150 W 100 W respectively. highest different fin circular which 51.29% at tip collector followed by rectangular 45.57% then 42.28% lastly 35.82%. perforations fines show a significant transfer.
