Abstract

V delu smo obravnavali gretje keramične nosilne plasti električnega upora in LED svetila. Ob predpostavki, da se v tanki keramični nosilni plasti temperatura po prerezu malo spreminja, smo za analizo nestacionarnega prenosa toplote pri njenem gretju uporabili posplošeno kapacitivnostno metodo. Na osnovi z infrardečo termografijo izmerjenih nestacionarnih temperaturnih potekov na površini keramične nosilne plasti smo določevali stacionarno temperaturo keramične plasti v odvisnosti od debeline keramične plasti in sproščene generacije toplote v električnem grelniku ali v LED svetilu. Ob uporabi posplošene kapacitivnostne metode smo z analizo nestacionarnih temperaturnih potekov določili termične časovne konstante keramičnih nosilnih plasti.

Secondary title: Thermographic analysis of an electrical resistor heating on a ceramic layer
Secondary abstract: In this work the heating of the ceramic carrier layer of electrical resistance and LED lamp is discussed. Based on an assumption of small temperature differences in a cross-section of a thin ceramic carrier layer, a lumped capacitance method is used to analyse nonstationary heat transfer during heating. Using an infrared thermography of measured nonstationary temperature courses on the surface of the ceramic carrier layer, we determined the stationary temperature of the ceramic layer depending on the thickness of the layer and amount of generated heat in an electric heater or LED light. Using a lumped capacitance method, thermal time constants of ceramic carrier layers were determined by analysing non-stationary temperature courses.
