20.500.12556/RUL-143218 The numerical study on performance evaluation of a thermal switch capacitor in a magnetocaloric cooling device Compact, solid thermal control devices offer a new way to control the intensity and direction of heat flow between the components of a system, which is crucial for both optimized performance and safety. In this work we study a thin, silicon thermal switch capacitor (TSC) used for heat transport in a magnetocaloric cooling system. A numerical model was developed to quantify the effects of various operating conditions and design parameters on the performance of a magnetocaloric device with an embedded TSC. Based on realistic material properties, a maximum cooling-power density of 4000 Wm$^{-2}$ (2025 Wkg$_{mcm}^{-1}$) was obtained for a zero temperature span and an operating frequency of 20 Hz. The use of the presented device was demonstrated on a battery system, motivating further experimental studies to develop a new, compact cooling device that can be directly attached to a heat reservoir, making it desirable for a variety of applications. solid thermal switch capacitors thermal control devices magnetocaloric cooling heat pump materials science thermal engineering thermal property toplotno stikalni kondenzatorji toplotni kontrolni elementi magnetokalorične toplotne črpalke true false true Angleški jezik Slovenski jezik Članek v reviji 2022-12-08 10:05:35 2022-12-08 10:05:40 2024-03-01 10:13:24 0000-00-00 00:00:00 2022 0 0 20 str. iss. 12, art. 105517 Vol. 25 Dec. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 536 2589-0042 10.1016/j.isci.2022.105517 130246147 Petelin...-The_numerical_study_on_performance_evaluation_of....pdf Petelin...-The_numerical_study_on_performance_evaluation_of....pdf 1 4F14158476E4F5703B75C9A216FBCF4F 01a41d22d7a2319bd2bbc7a648d4ca0f32daf6ee5a3a913ed2da1e043ccf3c4d 2715b885-76d8-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=164819 https://www.sciencedirect.com/science/article/pii/S2589004222017898 1 542a9223-76d7-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=164818 Fakulteta za strojništvo 0 0 0
