摘 要
CPU的風扇動力特性對電腦的散熱性、穩(wěn)定性等有重要影響。若是風扇不能跟上CPU的發(fā)展,導致電腦的散熱性不穩(wěn)定,從而導致電腦燒壞當機。
本文主要闡述了CPU風扇的基本組成、評價風扇品質(zhì)的重要參數(shù)、風扇性能測試的基本原理等。在分析計算的基礎(chǔ)上建立風扇外形的3D實體模型,選用pro-e軟件作為3D實體造型平臺,建立風扇3D實體模型,再導入GAMBIT中。進行不同參數(shù)風扇外形外流場計算區(qū)域的網(wǎng)格劃分,生成計算網(wǎng)格和確定邊界條件,利用GAMBIT 中的mesh 模塊,對已建立的風扇外形3D實體進行計算網(wǎng)格的劃分。將輸出的網(wǎng)格文件輸入FLUENT求解器中對不同參數(shù)風扇外形外流場計算區(qū)域進行流場計算分析、判斷計算結(jié)果,得到何種參數(shù)的風扇散熱最優(yōu)。

ABSTRACT
Characteristics of CPU fan power have a major impact on the computer cooling, stability, etc. If the CPU fan can not keep up with the development, resulting in cooling computer unstable, it will lead to burn a computer crash.
This paper describes the basic components of CPU fan, the important parameters to evaluate the quality of the fan, the basic principles of fan performance testing . In the analysis and calculation based on the fan shape established the 3D solid model, selected pro-e software as a 3D solid modeling platform for the establishment of the fan 3D solid model, and then import in GAMBIT. The fan shape of different parameters to calculate flow field region meshing to generate computational grid and determine the boundary conditions, the mesh using GAMBIT modules that have been established fan shape 3D entities computing grid division. The output grid file input FLUENT solver for different parameters of the fan shape of the outflow region flow field calculation calculation and analysis, to determine the calculated results,then know what kind of parameters to be the optimal cooling fan.
