Performance study of magnetic cooling system using kerosene based ferrofluid under magnetic field effect

Thermal management of modern electronic circuitry is important as it governs the reliability and life of any miniaturized electronic circuit. The active cooling techniques are not efficient in removing the high heat load generated by these miniature devices. The passive cooling is the next generation cooling. This paper is an attempt to measure the performance using magnetic cooling passive system in terms of heat transfer coefficient using kerosene based ferrofluid and to evaluate the effect of parameters like temperature and pressure head of kerosene based ferrofluid. COMSOL Multiphysics modeling software has been used for analysis. The results after numerical analysis showed that the convective heat transfer coefficient increased with the use of kerosene based ferrofluid as compared to natural convection coefficient.
