摘要

计算机经常会遇到CPU损坏,特别是主板和处理器损坏,原因有几个,包括人为错误或过度使用和环境条件。组件放置经常被用来改善CPU房间的条件,以保持它的凉爽。本研究以数值方法探讨桌面PC机处理器与散热器配置对机械工程职业学习的影响。金属材料的种类、风扇的数量、风扇的布置都在三个层面进行了测试。本研究中的计算机组件包括CPU、散热器、风扇和处理器——一个65瓦的热设计功率(TDP) CPU,进气速度恒定为5米/秒。调查标准包括金属类型(钢、铝、铜)、冷却设计(水平、垂直、混合)、风扇数量(2-4-8)。本研究采用计算流体动力学(CFD)方法和田口法来研究流体的流动特性和温度。数值结果表明,在垂直、八扇和钢结构下,最高温度为123℃。最低温度39.22°C在混合配置,八个风扇,和铜。这些发现表明,金属材料的种类、风扇的数量和风扇的排列都会影响CPU冷却器和散热器的配置。然而,田口方法可以提供对配置的更详细的理解。

Numerical study optimation design of CPU cooling system analysis using CFD method
Computers often experience damage to the CPU, especially the mainboard and processor, due to several factors, including human error or excessive use and environmental conditions. Component placement is frequently utilized to improve the CPU room conditions to keep it cool. This research numerically investigates desktop PC processors and heatsink configurations for mechanical engineering vocational learning. The kind of metal material, number of fans, and fan arrangement were all tested at three levels. The computer components in this research are the CPU, heatsink, fan, and processor—a 65-watt Thermal Design Power (TDP) CPU with a constant air intake speed of 5 m/s. The criteria investigated include metal type (steel, aluminum, and copper), cooling design (horizontal, vertical, and mixed), and fan count (2-4-8). The methods used in this research are the Computational Fluid Dynamics (CFD) method and the Taguchi method to examine fluid flow characteristics and temperature. Numerical results show the maximum temperature is 123 °C in the vertical, eight-fan, and steel configurations. Minimum temperature 39.22 °C in mixed configuration, eight fans, and copper. These findings reveal that the kind of metal material, number of fans, and fan arrangement all impact the CPU cooler and heatsink configuration. However, the Taguchi method can provide a more detailed understanding of configuration.
