Abstract：
This paper focuses on the emergency cooling of the data center, conducts a numerical simulation study on the energy discharge process of the cold storage tank designed with a new flared type water diffuser under the condition of large flow rate and small temperature difference, obtains the temperature field and temperature variation curve of the energy discharge process, and calculates the dimensionless thermocline thickness and the energy discharge efficiency. The numerical simulation results are compared with those of the ideal model and the actual project monitoring data to verify the working performance of the new flared type water diffuser.
