基于有限元的阀组件单级散热模块数值分析

简述了阀组件单级散热模块的外部模型、内部水路的物理模型和电子元件的分布。在理论计算分析的基础上，采用有限元的方法进行数值模拟，从而得到不同流速下的流阻和热阻，分析得到最佳冷却流速。借助有限元流体分析软件，得到了阀组件的温度场和流场，分析结果能够较真实地反映出散热模块的温度分布梯度、内部流场的温度梯度以及压力损失梯度。研究结果不仅为后续多级散热模块串联提供了理论基础，而且对散热器的设计和优化具有一定的指导意义。

Numerical Analysis of Valve Components Single-stage Cooling Module Based on Finite Element

This paper presents the external model of single stage cooling module, the physical model of internal waterways and the distribution of electronic components for the valve components. On the basis of theoretical analysis, numerical simulation is carried out using finite element method. The flow resistance and the heat resistance under different flow velocity are got. After analysis, the best cooling flow velocity is obtained. Using finite element fluid analysis software, the temperature field and the flow field of the valve components are obtained. Analysis results can truly reflect the temperature gradient of cooling module, the temperature gradient of internal flow field and the gradient of pressure loss. The study results not only provide the theoretical foundation for subsequent multi step cooling module series, but also provide good guidance for the design and optimization of the radiator.
