Design approach for subsea data center based on thermodynamic theory under the premise of building energy conservation

Traditional data centres often require additional energy to drive air conditioning fans etc. to dissipate heat due to the serious power generation problems of servers, which in effect raises the economic costs. Seawater, with its high specific heat capacity and fluidity, offers a viable research direction for reducing economic costs, and this paper is based on this problem. The study shows that it is feasible to use containers as the main structure of the data centre. The number of servers n 860 that can be tolerated by the cooling capacity of the container without considering the limit of geometrical constraints is obtained by calculation. Secondly, in order to enhance the heat dissipation capacity of the data centre, the 6 cm straight ribbed crown fin heat dissipation enclosure is proposed to have the best heat dissipation capacity when comparing various heat dissipation enclosure configurations. A comprehensive assessment model of material properties was established, and the weights of each straight index were determined by analytic hierarchy process, and then the metals were ranked according to the specific scores of each index. The results show that nickel alloys and aluminium alloys are the most suitable.
