Abstract: High current electrical feedthroughs are critical components in industrial furnaces operating under vacuum or controlled atmospheres, enabling processes like sintering, melting, crystal growth, and heat treatment. The transmission of thousands of amperes through feedthroughs presents significant challenges in thermal management, electrical efficiency, structural integrity, and sealing. Water cooling has emerged as the dominant solution for managing the intense Joule heating generated. This review synthesizes key literature on the design principles, analytical approaches, material selection, cooling system optimization, failure mechanisms, and performance validation of high-current water-cooled feedthroughs for furnace applications. The analysis highlights the multidisciplinary nature of this engineering challenge, encompassing electromagnetics, thermodynamics, fluid dynamics, structural mechanics, and materials science.
