Abstract

V magistrskem delu smo analizirali delovanje električno vzbujanega toplotnega stikala, ki omogoča časovno nadzorovan prenos toplote. V prvem delu smo zasnovali eksperimentalno progo, na kateri smo izvedli parametrično analizo delovanja toplotnega stikala. Osredotočili smo se na vpliv frekvence delovanja in gostote grelne moči pri doseženem preklopnem razmerju. Nato smo delovanje toplotnega stikala analizirali še numerično v programu TCC Builder. Numerične simulacije smo validirali z eksperimentalno pridobljenimi podatki. Rezultati kažejo, da numerične simulacije v splošnem dobro popisujejo delovanje toplotnega stikala, pri čemer večja odstopanja med eksperimentalnimi in numeričnimi rezultati nastopijo pri nizkih frekvencah delovanja. Raziskava omogoča boljše razumevanje delovanja električno vzbujenih toplotnih stikal in podaja smernice za izboljšanje delovanja izdelanega toplotnega stikala.

Secondary title: Design and characterisation of an electrically actuated mechanical thermal switch
Secondary abstract: In this master's thesis, we investigated the operation of an electrically actuated thermal switch for time-controlled heat management. In the first part of the study, we designed an experimental setup to perform a parametric analysis of the performance of the thermal switch. The analysis focused on the effects of operating frequency and heating power density on the achieved switching ratio. Subsequently, the operation of the thermal switch was numerically analyzed using the TCC Builder program. The numerical simulations were validated against the experimental results. The results show that the numerical simulations accurately predict the behavior of the thermal switch, although larger deviations can be observed at lower operating frequencies. This master's thesis contributes to a deeper understanding of electrically actuated thermal switches and provides guidelines for improving the performance of the manufactured thermal switch.
