Optimal Design of Container in Submarine Data Center Based on Heat Conduction and TOPSIS Index System

This paper mainly studies the heat dissipation process of the container in the submarine data center, calculates the number of servers by establishing a one-dimensional heat conduction equation, and establishes an optimization model to optimize the shell structure and material requirements of the container. Firstly, based on the Fourier heat conduction equation and Newton’s cooling law, a one-dimensional heat conduction equation is established. After setting the initial value and constraint conditions, the finite interpolation method is used to solve the equation group, and the distribution function in the space-time dimension is obtained, and then the maximum number of servers is obtained according to the working conditions of the server. Secondly, three kinds of common fin structures are selected, and the equations are established using the hydrodynamics control equation and the law of conservation of energy. The three kinds of fin structures are compared, and the heat transfer coefficient is considered. Finally, the corrugated fin is selected as the shell design of the container, and its material is optimized, and it is calculated that the most suitable metal material is maraging 300 steel. Finally, the influence of temperature change and tide change is analyzed, and the variation law of tide and temperature with time is explored by establishing a time series diagram, and the influence of tide and temperature on container heat dissipation is analyzed. It is concluded that tide and temperature will fluctuate with time, which should be predicted in advance to prevent server damage.
