摘　　要：为了解决加固计算机强迫风冷散热系统中风机如何选型的设计问题,结合具体加固计算机的散热风道结构,提出了风机选型设计计算方法,给出了具体的风机选型设计实例。利用计算机辅助热分析软件ANSYS Icepak,给出了软件设定中风机具体参数的设定方法。对风机在加固计算机的散热特性进行了分析模拟,通过对实际分析模拟结果的对比,得出了在加固计算机散热系统中和自身之间风机稳定工作点存在的差异。根据实际的分析模拟结果,对加固计算机的风机安装和风道结构进行了结构优化,从而表明了加固计算机的结构设计与风机散热特性之间的制约关系。In order to solve the problem of how the selection of design fan forced air-cooling system of the reinforcement computer, combined with cooling duct structure of specific reinforcement computer, fan selection design and calculation methods is proposed, and a specific design example of fan selection is given. And computer-aided thermal analysis software ANSYS-Icepak is wtilizd to analyze and simulate the fan cooling characteristics in the rugged computers, a set way of specific parameters of fan in the sofeware is given. By comparison of the actual results analyzed and simulated, the different of fan stable operating point exists between the cooling system of rugged computers and its own are obained. According to the actual analysis and simulation results, the structure of fan installed and cooling channel is optinized relationship between the structural design of reinforced computer and in the reinforcement computer, Thus prove the restrictive fan cooling characteristics.
