20.500.12556/RUL-126298 Bulk relaxor ferroelectric ceramics as a working body for an electrocaloric cooling device The electrocaloric effect (ECE), i.e., the conversion of the electric into the thermal energy has recently become of great importance for development of a new generation of cooling technologies. Here, we explore utilization of [Pb(Mg1/3Nb2/3)O3]0.9[PbTiO3]0.1 (PMN-10PT) relaxor ceramics as active elements of the heat regenerator in an ECE cooling device. We show that the PMN-10PT relaxor ceramic exhibits a relatively large electrocaloric change of temperature TEC >1 K at room temperature. The experimental testing of the cooling device demonstrates the efficient regeneration and establishment of the temperature span between the hot and the cold sides of the regenerator, exceeding several times the TEC within a single PMN-10PT ceramic plate. electrocaloric cooling devices bulk relaxor ferroelectric ceramics active electrocaloric regenerators aktivni elektrokalorični regeneratorji elektrokalorična hladilne naprave masivna relaksorska feroelektrična keramika true false true Angleški jezik Slovenski jezik Članek v reviji 2021-04-15 14:34:42 2021-04-15 14:34:43 2022-09-05 03:54:38 0000-00-00 00:00:00 2015 0 0 Str. 1-4 iss. 4, art. 043903 Vol. 106 2015 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.565(045) 0003-6951 10.1063/1.4907258 13878299 24984832 RAZ_Plaznik_Uros_2015.pdf RAZ_Plaznik_Uros_2015.pdf 1 A2F18E66EA2305E99D513A8518408199 a943ab3c5a0d25cbebd2af9d1dd17145e10cf91dce10344d910b54985aae7d1b e1a260f1-a1bb-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=142201 https://aip.scitation.org/doi/10.1063/1.4907258 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=142202 Fakulteta za strojništvo 0 0 0
