摘要

由于小型化、可用空间和重量的限制,当今的ecu(电子控制单元)面临着在非常小的体积内安装高功率密度的问题。由于这个原因,由此产生的散热变得越来越难以管理,并且正在朝着这个方向不断努力优化热管理。本文采用六西格玛设计方法,通过在风扇转速和散热片之间的距离之间找到最佳配置,显示了散热性能的改善。重点是找到一个可靠的传递函数,可以预测确定的关键设计参数的影响。推导并分析了两个传递函数;一种基于实验设计(DoE),另一种基于简化热理论。将传递函数和预测结果的准确性与Ansys Icepack程序中的热模拟结果进行了比较。这表明,使用基于少量模拟的DoE方法足以估计ECU的行为,而无需使用更复杂的理论方法。

Optimization of Heat Dissipation for Fan Cooling Solution
Abstract Today’s ECUs (Electronic Control Units) face a high-power density mounted in a very small volume due to miniaturisation, available space, and weight limitations. For this reason, the resulting heat dissipation has become increasingly difficult to manage and continuous efforts are being made to optimize thermal management in this direction. This paper shows an improvement in heat dissipation by finding an optimal configuration between the fan speed and the distance between the cooling fins using the Design for Six Sigma methods. The focus was on finding a reliable transfer function that could predict the influence of the identified critical design parameters. Two transfer functions were derived and analysed in parallel; one based on Design of Experiments (DoE) and another based on simplified thermal theory. The accuracy of the transfer function and predictions were compared with the results of thermal simulations performed in the Ansys Icepack program. This shows that the use of the DoE method based on a small number of simulations is sufficient to estimate the behaviour of the ECU, without using a more complex theoretical approach.
