AB - 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.
