Abstract
Immersion and jet technology is the future development direction of data center server liquid cooling.A single-server liquid cooling test bench was built to compare the heat dissipation performance of pure immersion and immersion jet liquid cooling systems.On this basis,the effects of inlet water temperature,jet distance and inlet water flow rate on the performance of immersion jet system were analyzed.The experimental results show that in the pure immersion liquid cooling system,the inlet water temperature is reduced from 27.0℃to 18.0℃,which can reduce the stable temperature of the server surface from 47.4℃to 41℃,but it also increases the temperature difference between the inlet and outlet water.In the submerged jet liquid cooling system,when the jet distance is reduced from 10 cm to 1 cm,the steady-state surface heat transfer coefficient can be increased by about 467.3 W/(m2·K),and the heat exchange uniformity of the system is better at 3 cm.The steady-state surface heat transfer coefficient can be increased to 3136.2 W/(m2·K)when the inlet water flow rate is increased from 8 L/min to 18 L/min,which is about 2.1 times of that at low flow rate.Subsequently,the potential of submerged jet liquid cooling technology in large-scale applications can be further explored.关键词
