20.500.12556/RUL-141694 Fractal geometry as an effective heat sink Fraktalna geometrija reber za učinkovit hladilnik "How long is the coast of Britain?" was the question stated by Mandelbrot. Using smaller and smaller rulers the coast length limits to infinity. If this logic is applied to the fractal heat sink geometry, infinite cooling capacity should be obtained using fractals with mathematically infinite surface area. The aim of this article is to check this idea using Richardson extrapolation of numerical simulation results varying the fractal element length from one to zero. As expected, the extrapolated heat flux has a noninfinite limit. The presented fractal heat sink geometry is non-competitive to the straight fins. fractal heat sink LED cooling CPU cooling conjugate heat transfer laminar flow boundary element method Koch snowflake fraktalno hladilno telo LED hlajenje CPU hlajenje konjugirani prenos toplote laminarni tok metoda robnih elementov Kochova snežinka true false true Angleški jezik Slovenski jezik Članek v reviji 2022-10-05 09:23:00 2022-10-05 09:23:03 2022-10-06 03:50:34 0000-00-00 00:00:00 2022 0 0 Str. 517-528 no. 9 Vol. 68 Sep. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-09-01 621.56:536.24 0039-2480 10.5545/sv-jme.2022.28 124223491 Ramsak_-_Fractal_geometry_as_an_effective_heat_sink.pdf Ramsak_-_Fractal_geometry_as_an_effective_heat_sink.pdf 1 43CE61570861E5EBFC198F20E0C42A21 7a4269348781c176f105334457ee13bb67ecb006ccea8cd5dd7ff012332b41b0 fb50e486-447e-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=162806 https://www.sv-jme.eu/sl/article/fractal-geometry-as-an-effective-heat-sink/ 1 89fa80e4-447e-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=162805 Fakulteta za strojništvo Strojniški vestnik 0 0 0
