Application of Peltier effect on thermoelectric module

Ovim radom se proučavaju tri međusobno povezana efekta koji su dobili nazive po njihovim pronalazačima: pretvaranje razlike topline u električnu energiju po Seebecku, pretvaranje električne energije u razliku topline po Peltieru te konačna matematička formula efekta po Kelvinu. Posebno se navodi Peltier i efekt razlike topline jer je takozvani peltierov element korišten u izradi pasivnog hladnjaka te je njegova izrada dokumentirana u ovom radu. Naglasak rada je na izradi malog prenosivog hladnjaka gdje se želi pokazati praktičnost peltierovog elementa zbog izostanka pokretnih komponenti što pridonosi dugovječnosti elementa i sukladno time cijelog sklopa.This paper examines three interrelated effects named after their inventors: the conversion of heat difference into electricity by Seebeck, the conversion of electricity into heat difference by Peltier, and the final mathematical formula by Kelvin. In particular, Peltier and the effect of heat difference are mentioned, since the so-called Peltier element was used in the design of the passive cooler and its production is documented in this paper. The emphasis of the work is on the design of a small portable refrigerator where the practicality of the Peltier element is to be demonstrated due to the absence of moving components, which contributes to the longevity of the element and accordingly the whole assembly
