.用ANSYS\FLOTRAN模块对CPU（带风扇）强制风冷散热分析可行嘛？

由此疑问是基于比较了在同样的模型下热分析与用FLOTRAN进行热流分析（自然对流情况下）的结果，发现在相同的载荷下，两者的结果差别很大。当然，热分析的结果比较合理，热流分析出来的太离谱了。有那位高手做过这方面的分析，请指点迷津，谢谢。

强制风冷散热分析可行嘛？

我也想做这个，你会麽教教我，我初学...

Probably Ansys is not good at this kind of system level cooling involoving forced convection from fan. Maybe Icepak is better choice?
My another two cents: what's the purpose of doing such simulation?  If you want to see the CPU temperature rise, you can just apply effective convective heater transfer coefficient on heat sink or lid in Ansys and no need to run such complicated system-level problem.
The key of the thermal analysis is to simplify the problem such that minimum effort is used to get relative good result. DO NOT rely on simulation as you don't know a lot of parameters, such as thermal property, boundary conditions, etc.
