The Zero-Emissions Driving System (ZEDS), equipped with a Magnetorheological (MR) brake, is a transformative approach to braking systems in automotive technology. MR brakes leverage the unique properties of Magnetorheological Fluids (MRF) to provide controlled braking without relying on friction, thus eliminating particulate emissions and reducing wear. However, a significant challenge faced by this system is the high heat generation during intensive braking maneuvers. Excessive heat can compromise the operational integrity of MRF, necessitating advanced cooling strategies to maintain safe and efficient functionality. Liquid cooling is considered the optimum cooling method for our case due to the high power heat generation of MRF during braking.
