Thermal Simulation Software Introduce.ppt

Dell Non-confidential First Part Benefit of Thermal Simulation Software Background: Clock speed/semiconductor density is increasing, electrical devices are dissipating more heat. Thermal design becomes more and more critical. Goal of Thermal Design has changed. 1. Previous thermal design goal 100％ thermal design success 2.Current thermal design goal a. Short Time b. Low Cost c. Optimization Design and optimize Heat sink Design and optimize duct/vent Design and optimize duct/vent Design and optimize duct/vent Design and optimize duct/vent Select and optimize fan Optimize components/system layout Display airflow and Temp layout Benefit of CFD (Computational Fluid Dynamic) 1.Reduce Cost 2.Shorten RD Life/Cycle 3.Optimize Thermal Design Conclusion CFD software is an effective thermal design tool. Second Part Introduce for IcepakFlotherm Two kinds of CFD Software 1.Flotherm 2.Icepak 1.The main difference between Icepak and Flotherm Icepak和Flotherm的最大区别 ICEPAK uses non-construction mesh使用非结构化网格 Flotherm uses construction mesh.使用结构化网格 2.Solver: Icepak use Fluent5 as solver Flotherm use its own solver Icepak使用Flunt5计算求解器 Flotherm使用自己的专用求解器 3.Flotherm is developed by Design-Class user Flotherm由Design-Class（设计级）分析方法的倡导者所开发 Flotherm is more useful for system thermal analysis Flotherm更适合用于对系统建模分析 Icepak is more fit for components level analysis Icepak做零组件级热分析更有优势 Suggestion: 建议: Use Flotherm do analysis for system 用Flotherm来分析系统 Use Icepak do analysis for components 用ICEPAK来分析热组件 4. Liquid cooling system simulation模拟液冷系统： Hard for Flotherm/Flotherm难度大 Easy for Icepak/Icepak相对容易与便利 5. IGES用户图形界面 Flotherm is more friendly/Flotherm更人性化 Icepak is not so friendly/ Icepak较弱 6.Tech support技术支持 Flotherm has good tech support/Flotherm 非常到位 Icepak is weak/Icepak 相对较弱 7.Automatic Optimization Flotherm has strong automatic
