重力对新型大功率环路热管传热性能影响的实验研究OA北大核心CSTPCD

To solve the problem of huge energy consumption caused by data center cooling,this paper proposes a high-power air-cooled loop heat pipe that can be used for data center server cooling.The effect of gravity on the heat transfer performance of the loop heat pipe was explored through a large number of comparative experiments.The experimental results show that the gradient capillary structure and the method of re-cooling the reflux liquid proposed in this paper can effectively improve the heat transfer performance of the high-power loop heat pipe in different gravity modes.The loop heat pipe with optimized structure has a maximum heat transfer capacity of 950 W and a minimum total thermal resistance of 0.1 ℃/W in gravity-assisted mode.In addition,the high-power loop heat pipe proposed in this paper successfully operated in the anti-gravity mode.
