20.500.12556/RUL-128882 Thermal rectification in multilayer phase change material structures for energy storage applications Solid-state thermal control devices that present an asymmetric heat flow depend-ing on thermal bias directionality, referred to as thermal diodes, have recentlyreceived increased attention for energy management. The use of materials thatcan change phase is a common approach to design thermal diodes, but typicalsizes, moderate rectification ratios, and narrow thermal tunability limit their po-tential applications. In this work, we propose a multilayer thermal diode made ofa combination of phase change and invariant materials. This device presentsstate-of-the-art thermal rectification ratios up to 136% for a temperature rangebetween 300 K and 500 K. Importantly, this design allows to switch betweendistinct rectification states that can be modulated with temperature, achievingan additional degree of thermal control compared with single-rectification-statedevices. We analyze the relevance of our thermal diodes for retaining heat moreefficiently in thermal storage elements. energy engineering materials science energy materials thermal control device thermal diode heat storage gospodarjenje z energijo znanost o materialih energijski materiali toplotni kontrolni element toplotna dioda toplotni regulator shranjevanje toplote true false true Angleški jezik Slovenski jezik Članek v reviji 2021-08-11 13:05:19 2021-08-11 13:05:23 2023-11-29 09:26:10 0000-00-00 00:00:00 2021 0 0 Str. 1-14 iss. 8, art. 102843 Vol. 24 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 536:620.1/.2 2589-0042 10.1016/j.isci.2021.102843 72781059 RAZ_Swoboda_Timm_2021.pdf RAZ_Swoboda_Timm_2021.pdf 1 DF82FB7CEC924D545D0A40D21D25643D 2ac57eea24ef90fd23f63705b2de9c55234ba76c5e77bab8bdebba01fa98c901 f3b0e5f3-fa94-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=145787 https://www.sciencedirect.com/science/article/pii/S2589004221008117 1 d46da0a8-fa93-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=145786 Fakulteta za strojništvo 0 0 0
