20.500.12556/RUL-130348 Prenosniki toplote izdelani z aditivnimi tehnologijami: Materiali in uporaba Heat exchangers made with additive manufacturing technologies: Materials and applications Aditivne tehnologije omogočajo izdelavo prenosnikov toplote, ki jih predtem ni bilo mogoče izdelati zaradi omejitev konvencionalnih izdelovalnih postopkov. Novi tako dobljeni dizajni so tehniško precej boljši od klasičnih konceptov ter hitrejši in enostavnejši za izdelavo. V delu so opisane klasične izvedbe prenosnikov toplote in njihovo dimenzioniranje, opisane so najpomembnejše tehnologije 3D tiskanja, opisane so prednosti in slabosti teh tehnologij na splošnih primerih in primerih izdelave prenosnikov toplote. Teoretičnem delu sledi eksperimentalna analiza in primerjava tlačnih padcev dveh različnih 3d tiskanih prenosnikov toplote, ki imajo pretočne kanale različnih oblik. Additive manufacturing technologies make it possible to manufacture heat exchanger designs that were impossible to make in the past because of the limitations of conventional manufacturing technologies. Newer designs enabled by additive manufacturing are in some regards technically superior and in some cases cheaper and quicker to manufacture than their classical counterparts. In this work we described the classical heat exchanger designs, and some general methods of sizing. We described the most important types of additive manufacturing technologies along with their advantages and limitations in the manufacturing of heat exchangers. In the experimental part of this work we designed two different designs of a heat exchanger with differently shaped channels and performed a pressure drop analysis. prenosniki toplote aditivne tehnologije tlačne izgube regenerator optimirani prenosniki toplote materiali za prenosnike toplote heat exchangers additive manufacturing pressure drop regenerator optimized heat exchangers materials for heat exchangers true false false [D.
