浸没式液冷服务器排列方式研究
Research on server arrangement of liquid immersion cooling systems
摘要：
浸没式液冷是一种新兴的服务器冷却方式，即将服务器主板浸泡在绝缘换热介质中通过沸腾来增强换热。本文采用ANSYS软件模拟了浸没式液冷系统中服务器主板不同布置方式和间距下的流体温度场和速度场。结果表明：服务器主板竖放可以让壁面产生的气泡顺利排出，横放会造成气泡在主板下方聚集从而影响其换热；当服务器主板间距小于50 mm时，主板产生的气泡会在板间合并，影响传热，因此主板间距应设置在50 mm以上。
Abstract：
The liquid immersion cooling system is a new cooling method for data centers, which can enhance heat transfer by soaking the server motherboard in the insulating heat exchange medium to boiling. In this paper, the fluid temperature and velocity fields under different arrangements and spacing of the server motherboards in the liquid immersion cooling system are simulated by ANSYS software. The results show that the vertical arrangement of the server motherboards can smoothly discharge the bubbles generated on the wall, while the horizontal arrangement will cause bubbles to gather under the motherboards, thus affecting heat dissipation. When the spacing between the motherboards is less than 50 mm, the bubbles generated by the motherboards will merge between the plates and affect the heat transfer, so the motherboard spacing should be set above 50 mm.
