  • Development of tube-based structures to be applied in durable and efficient elastocaloric cooling device [Elektronski vir]
    DallʹOlio, Stefano ...
    Elastocaloric cooling technology, which utilizes the latent heat released/absorbed during the forward/reverse martensitic phase transformation in superelastic shape memory alloys (SMA), is being ... recognized as a promising alternative to the nowadays widely applied vapor-compression technology. Accordingly, different concepts of elastocaloric devices have been proposed and designed in recent years. The most promising overall cooling (heat-pumping) characteristics was obtained by active elastocaloric regenerator, which is a porous structure made of elastocaloric material thorough which a heat transfer fluid is pumped in a counter-flow direction. After a brief introduction and short overview of elastocaloric technology, the main challenges in designing durable and efficient compression-loaded elastocaloric regenerators will be discussed. Since superelastic Ni-Ti tubes seem to be the ideal candidates for elastocaloric regenerators loaded in compression, numerical and experimental analyses of buckling stability, fatigue behavior and heat transfer characteristics of tube bundles would be presented next. Finally, the first experimentally obtained cooling and heat-pumping characteristics of a novel tube-based elastocaloric regenerator in a new elastocaloric setup will be presented.
