The factors affecting the heat transfer of the rotating cathode are analyzed, and a design scheme of the cathode cooling system is proposed. Based on the theory of fluid mechanics and heat transfer, according to the principle of organizing the experimental data and the empirical formula, the rotating cathode heat transfer mathematical model was designed to calculate the performance parameters of the water cooling system. The fluid-solid coupling method Analysis and numerical simulation of the cathode transient heat transfer under actual working conditions, the law of the cathode heat transfer state and temperature distribution over time are obtained, and the calculation results of the performance parameters of the water cooling system of the heat transfer mathematical model are further verified. This combination of numerical and finite element simulation ideas and methods for the design and optimization of the rotating cathode cooling system provide a theoretical basis and an important reference.
