Abstract

U ovom radu opisan je rad Peltierova uređaja. Za isti je dan teorijski model koji predviđa njegovo toplinsko ponašanje kad se nalazi između dva materijala. Model se riješio numeričkom metodom i provjerio eksperimentalnim mjerenjima temperatura pri različitim strujama rada Peltierova elementa. Kao rezultat dobiven je graf ovisnosti temperatura na hladnoj i toploj strani Peltierova elementa o vremenu. Napravljena je usporedba ovog modela s literaturnim i raspravljen je utjecaj parametara na rezultate modela.

Abstract (english)

This study describes the work process of a Peltier device. A theoretical model is given which predicts its behaviour when placed between two materials. The model is solved by a numerical method and validated with experimental measurements of temperatures at different current strengths. The result is a graph consisting of temperatures at cold and hot side versus time. This model is compared with existing literature and the influence of its parameters on the results is discussed.
