摘要
针对伺服驱动器发热量较大、温升过高等问题,将热动力仿真分析结合工程设计经验的技术应用到散热器优化设计中。采用有限体积法数值模型仿真的方法,研究了在自然对流条件下散热器截面形状尺寸对散热效率的影响。通过对比仿真分析的温度场分布图,优选出了散热器最佳设计方案。研究结果表明,利用仿真分析结合工程设计经验,在同等加工工艺性和经济性等条件下散热器散热效率提高了6.8%,增加了产品的可靠性。
Aiming at the problems of servo driver higher heat and temperature, the CFD analysis technology based on the experience of engineering applying to the optimization design for heat-sink was investigated. The finite volume method for the numerical simulation was adopted to research the influence of the shape and the size of the heat-sink under natural convection conditions on thermal efficiency. The optimal design was chosen contrasted the simulation analysis of the distribution of the temperature field. The results indicate that, the heat radiation efficiency is improved 6.8% ,using the simulation analysis based on the experience of engineering design,under the same conditions of processing technology and economic. The reliability of the products is increased.
