Kalorični hladilni sistemi zaradi visokih učinkovitosti in okolju neškodljivih hladilnih sredstev kažejo velik potencial na področju hlajenja. Magistrsko delo obravnava numerično analizo hladilnega sistema za hlajenje elektronskih komponent na osnovi elastokaloričnega in elektrokaloričnega učinka. Razvili smo ustrezen fizikalno-matematični in nadalje numerični model, ki omogoča parametrično analizo in optimiziranje takšnega sistema. Rezultati kažejo, da je takšen miniaturni hladilni sistem sposoben odvesti do 0,3 W/cm^2 toplotne moči in ima lahko hladilno število do 15 pri temperaturni razliki okoli 1 K. S tem smo dokazali potencial in omejitve miniaturnih kaloričnih hladilnih sistemov, ki bi v prihodnosti lahko imeli pomembno vlogo pri hlajenju elektronskih komponent.

• Title: Analysis of micro cooling system based on elastocaloric and electrocaloric effect

Abstract

Cooling systems based on caloric effects show great potential, due to their high efficiencies and the lack of environmentally hazardous substances needed for their operation. In this work a numerical analysis of a cooling system designed for cooling of electronic components based on elastocaloric and electrocaloric effects is performed. A mathematical model and further numerical model, which enables parametric optimization of such a system is developed. The results show that this kind of micro cooling system can have a cooling capacity up to 0,3 W/cm^2 and maximum COP values up to 15 at temperature span of around 1 K. With this, we proved the potentials and the limits of caloric micro cooling systems, which could play an important role in cooling of electronic components in the future.
