Research on heat dissipation optimization of servers in a computer room under different air supply modes

Abstract

Abstract The computational fluid dynamics method is used to study the internal heat dissipation of the original computer room, analyze the reasons for unreasonable temperature distribution, and optimization is adopted. According to the optimized computer room, the flow field and temperature field of two air supply modes are studied, and the results under different inlet air temperatures and flow rates are compared. The results show that the local temperature on both sides of the original computer room is too high, which is because the center of the server on both sides is not effectively ventilated and dissipated. The heat dissipation effect is optimized by adding the upper and lower air vents on both sides of the room, respectively. The calculation shows that the optimization effect is obvious. The top-to-bottom air supply mode and bottom-to-top air supply mode can have a good effect on the heat dissipation of the computer room, but the top-to-bottom air supply mode has a better effect on the heat dissipation of the computer room. Considering factors such as energy saving and cooling effect, it is recommended to choose 44000 m3/h of air intake volume under the top-to-bottom air supply mode.
