摘要：

为揭示导风罩结构参数对多风扇冷却模块（MFCP）性能的影响，采用多重参考坐标系模型对风扇建模、采用多孔介质模型和热交换器模型对散热器建模，完成MFCP建模；搭建试验台架验证模型精度；利用该模型开展仿真计算.仿真结果表明：导风罩深度越大，模块气动和散热性能越好，性能可提升空间逐渐变小.考虑安装空间、制造成本等限制因素，定义最优导风罩深度（MOSD），利用仿真计算进一步探寻MOSD的影响因素.结果表明：模块中的风扇数量对MOSD的影响较小，对多风扇冷却模块导风罩深度的研究可简化为对单风扇冷却模块的研究；面积比越大，MOSD越大；长宽比参数（本研究取2.62）只有大到一定程度，才对MOSD有显著影响；散热器阻力特性和风扇转速对MOSD几乎没有影响.
Abstract:

The electrical fan module was established and numerically simulated by multiple reference frame method in order to study the performance of multi-fans cooling package (MFCP) influenced by shroud structural parameters. The radiator was simplified as porous medium, and the heat transfer characters was calculated by heat exchanger model. Then, the MFCP model was established. A test bench was set up to validate the simulation. According to the simulation, if the shroud was deeper, the aerodynamic and heat transfer performance of module would be developed, but the development would be minimized gradually. A parameter named most optimized shroud depth (MOSD) was defined according to the size and cost to evaluate the effect. To find out the MOSD further, it was found that there was little influence induced by the numbers of the fans, thus the study could be focused on the single fan module. The larger the area ratio is, the larger the MOSD is. The ratio of length and height do not influence the MOSD until it increases to a quite large value, which is 2.62 in our study. The effect by the radiator resistance and fan speeds are barely noticed.
