The importance of heat management has been emphasized in various industrial fields and cooling technology of efficiently removing heat is required. The natural convection of a fluid-filled enclosure is being applied in applications such as heat exchangers, solar energy collection, and electronics cooling. In this study, when the same heat source was applied, velocity, temperature, magnetic Rayleigh number, and local Nusselt number in the enclosure were analyzed according to the magnetic field strength and obstacles. The highest heat transfer performance was obtained at 2000 kA/m of rhombus and magnetic field strength. Finally, the optimum point that has a higher heat transfer rate than the reference model was derived by modifying the strength of the magnetic field.
