20.500.12556/RUL-96758 Analiza pretoka zraka in korozije lamelnih prenosnikov toplote v laboratorijskem preizkuševališču Analysis of air flow and lamella heat exchanger corrosion in the experimental test facility V diplomskem delu smo preučevali možnosti za izboljšanje hitrostnih razmer v pravokotnem zračnem kanalu laboratorijskega preizkuševališča. Na osnovi pregleda literature smo analizirali na trgu dosegljiva mrežna satovja in jih vgradili v zračni kanal. Pri tem smo v območju zračnega pretoka med 1000 m3/h in 2000 m3/h eksperimentalno določili hitrostne in temperaturne profile po prečnem preseku kanala pred in za prenosnikom toplote. Nadalje smo obravnavali korozijo na bakrenih ceveh lamelnega prenosnika toplote, ki jih uporabljamo kot hladilnike zraka. S pomočjo analize korodiranih površin na zunanji in notranji strani bakrenih cevi smo določili ključne vplivne parametre, ki povzročajo korozijo bakrenih lamelnih hladilnikov. This paper studies the possible improvements in air flow conditions in a rectangular duct with a heat pipe heat exchanger. Based on a review of literature we analysed different plates for air flow stabilisation that are available on the market and embedded them into the air duct. In the process we have experimentally determined velocity and temperature profiles along the cross-section and just behind the heat exchanger. Rate of air flow ranged between 1000 m3/h and 2000 m3/h. Furthermore we discussed the corrosion of lamella heat exchanger copper pipes that are used as air coolers. By analysing the corroded surfaces on the outer and inner sides of copper pipes we determined key parametres that cause corrosion of coppery lamella coolers. prenosnik toplote stabilizacija zračnega toka korozija meritve heat exchanger air flow stabilisation corrosion measurements true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-10-15 07:15:17 2017-10-15 07:15:25 2023-11-03 08:35:24 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 202086 1171.pdf 1171.pdf 1 FB20FB9C22D268B32E33554E1D58415D 9fbda6c9f57ce4f141894d2d7c0fa3fc901a966151cf3836fe50184bc2900c07 f93b6990-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/b4b47dcf-d306-4546-86b9-c53427afbd82 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=105513 Fakulteta za strojništvo 0 0 0
