The paper considers the prospects of using dielectric as a coolant in server cooling systems used in data centers and storage centers. This article discusses two methods of server cooling. The first method is the classic air method, where a stream of cooled air is brought to the server cabinets through the raised floor. The second method is more innovative. It involves filling each server with dielectric, which by means of natural convection circulates in the server and takes away the heat generated by the server components. Calculation and comparison of the two cooling techniques described above is carried out according to the following main parameters: analysis of capital costs and energy efficiency of the cooling system. All parameters in question are considered at various server rack densities. As a result of a comparative analysis, the data on the advantage of liquid cooling, both in terms of capital costs for construction and energy efficiency, is obtained.
