Abstract:Veliko povpraševanje elektrifikacije osebnih in tovornih vozil z namenom zmanjšanja emisij je vodilo k velikemu napredku v razvoju elektromotorjev. Eden od načinov povečanja izkoristka in izboljšanja karakteristik električnih motorjev je obvladovanje in zmanjšanje termičnega presežka, proizvedenega pri obratovanju motorjev. Namen magistrskega dela je izboljšanje že obstoječega hlajenja permanentno magnetnega elektromotorja z dodatnim neposrednim oljnim hlajenjem. Z uporabo CFD numeričnih simulacij programskega paketa AVL FIRE M, so primerjani različni koncepti neposrednega oljnega hlajenja, kjer je cilj ustvariti čim bolj učinkovito metodo odvajanja toplote od kritičnih komponent motorja. Rezultati simulacij osnovnega hlajenja kot tudi posameznih konceptov so med sabo primerjani z namenom določanja najučinkovitejša hladilnega sistema za dan motor.

Title:Optimization of cooling of electric motors with oil spray by numerical simulation
Abstract:The high demand for electrification of personal and transport vehicles with the goal to reduce emissions and associated pollution, has led to major advances in the development of electric motors. To increase efficiency and improve characteristics of electric motors, thermal management and reduction of losses must be considered. The aim of this thesis is to improve the existing cooling method of permanent magnet electric motor by adding direct oil cooling. Using CFD numerical simulations, created using a AVL FIRE M software package, different direct oil cooling concepts were compared with the aim to increase heat transfer from critical engine components. The simulation results of the base cooling system as well as individual cooling concepts are compared to determine the most efficient cooling system for the given engine.
Keywords:cooling, electric motors, oil spray, numerical simulation
