Abstract:Magistrsko delo obravnava optimizacijo hlajenja centrifugalne naprave s pomočjo dodatnih hladilnih elementov, spremembe pretoka in poti zraka ter CFD analiz. Analizirani so bili vplivi različnih konfiguracij ventilatorjev in geometrijskih prilagoditev na temperaturo motorja ter vzorca in raven hrupa. Poseben poudarek je bil namenjen učinkovitosti kombinacije pasivnega in aktivnega hlajenja ter usmerjenega gibanja zraka skozi napravo. Eksperimentalni rezultati so pokazali, da ustrezna usmerjenost zračnega toka pomembno izboljša toplotno stabilnost naprave brez povečanja akustične obremenitve. Najboljša konfiguracija je omogočila znižanje temperature motorja za skoraj 7?°C in vzorca za več kot 6?°C. Razvita rešitev je bila zasnovana z vidika enostavne integracije v obstoječo serijsko proizvodnjo brez večjih konstrukcijskih sprememb. Delo prispeva k razumevanju povezav med zračnim tokom, temperaturno obremenitvijo in akustičnimi lastnostmi ter ponuja podlago za nadaljnjo optimizacijo laboratorijskih naprav.

Title:OPTIMIZATION OF A CENTRIFUGAL DEVICE
Abstract:The master's thesis investigates the optimization of cooling in a centrifugal device through additional cooling elements, modifications of airflow and flow paths, and CFD analyses. The effects of various fan configurations and geometric adjustments on motor and sample temperatures as well as noise levels were analyzed. Special emphasis was placed on the efficiency of combining passive and active cooling and the directed airflow within the device. Experimental results showed that proper airflow direction significantly improves thermal stability without increasing acoustic load. The best configuration achieved a temperature reduction of nearly 7 °C for the motor and over 6 °C for the sample. The developed solution was designed for easy integration into existing serial production without major structural changes. This work contributes to the understanding of the relationships between airflow, thermal load, and acoustic properties, and provides a foundation for further optimization of laboratory devices.
Keywords:centrifugal device, thermal load, sample temperature, cooling systems, cooling optimization, airflow simulation
