ABSTRACT

In recent years, due to the rapid growth of big data center in coastal cities, and the high cost of land construction, occupying more land, cooling consumes a lot of power and cold water resources, causing a prominent resource contradiction, thus the undersea data center project came into being. "Undersea data center project" does not occupy or rarely occupies land resources, saves energy consumption, does not need fresh water consumption, and can greatly shorten the distance between data and users, and has the characteristics of low cost, low delay, high reliability and high security, so as to realize the green and sustainable development of big data center. However, the project is a new project, there are still many areas to be improved. How to design the container shell structure for heat dissipation is a very worthy of discussion. Firstly, we determine the geometry of the container by comparing the surface area of the cuboid and the cylinder under the same volume; Then, in order to ensure more sufficient heat dissipation conditions, we consider increasing the surface area of heat dissipation by adding fins. A one-dimensional heat conduction model of thin-walled fin is established. Under different thermal conductivity conditions, rectangular fin, triangular fin or parabolic fin are arranged. Finally, we designed the overall shape of the container and select the material of the shell to ensure the best heat dissipation effect.
