20.500.12556/DKUM-66734 Cooling analysis of a light emitting diode automotive fog lamp Efficiency of cooling fins inside of a light emitting diode fog lamp is studied using computational fluid dynamics. Diffusion in heat sink, natural convection and radiation are the main principles of the simulated heat transfer. The Navier-Stokes equations were solved by the computational fluid dynamics code, including Monte Carlo radiation model and no additional turbulence model was needed. The numerical simulation is tested using the existing lamp geometry and temperature measurements. The agreement is excellent inside of few degrees at all measured points. The main objective of the article is to determine the cooling effect of various heat sink parts. Based on performed simulations, some heat sink parts are found to be very ineffective. The geometry and heat sink modifications are proposed. While radiation influence is significant, compressible effects are found to be minor. heat transfer cooling of electronic devices cooling fins light emitting diode automotive lamp compressible flow prenos toplote hlajenje elektronskih naprav hladilna rebra svetleče diode avtomobilska luč stisljivi tokovi true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-07-07 09:39:57 2017-07-07 09:40:49 2022-08-01 13:06:35 2019-07-11 15:57:11 2017 0 0 str. 757-766 št. 1B Letn. 21 2017 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 0354-9836 536:532 43417089 20476182 10.2298/TSCI140829140Z 0354-9836 URN:SI:UM:DK:WACNIXFI Thermal_Science_2017_Zadravec_et_al._Cooling_analysis_of_a_light_emitting_diode_automotive_fog_lamp.pdf Thermal_Science_2017_Zadravec_et_al._Cooling_analysis_of_a_light_emitting_diode_automotive_fog_lamp.pdf 1 588F4B13DD4A845773C7DE24FDF36C44 dedece993aa9ce9f8a31c6892f7c793a71314577abb2a3a24b1d69c6bb8bfd8e 5ffca671-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/d948ae26-250a-4242-acbb-a46c5ed711a0 https://dk.um.si/Dokument.php?lang=slv&id=113832 http://www.doiserbia.nb.rs/Article.aspx?ID=0354-98361600140Z 1 https://dk.um.si/Dokument.php?lang=slv&id=113831 Fakulteta za strojništvo 0 0 0
