Research Progress and Factors Analysis of Spray Cooling System in Data Center

With the rapid development of Internet and communication technology, the demand for construction and maintenance of the data center is increasing. At the same time, the problem of high heat dissipation in the data room has been provided. In order to apply spray cooling technology to the data center to solve the cooling problem ,the key elements of the spray cooling system are investigated by summarizing the problems of heat exchange, cooling source selection, fluid transmission configuration optimization and system control and feedback in the real application of spray cooling system to the data center. The advantages and disadvantages of different cooling sources applied in the data center are compared, as well as the overall optimization of the spray cooling system. On the basis, two key problems, the composition of the system pipeline and the way to optimize the overall medium recovery system, are discussed. And then the system linkage feedback adjustment device is proposed. The results show that the selection of cooling source should not only meet the requirements of spray cooling, but also match with the spray cooling system. The design of system pipeline should be proposed based on reducing flow resistance and designing optimal pipeline distribution. The normal operation of the spray cooling system in the data center can be guaranteed by combining the active control system and the passive control system. The content involved in this paper can provide reference for the application of spray cooling system in the data center.
