摘要

本文介绍了几种不同的基于自然对流的增材制造开关磁阻电机散热器设计的数值模型。所提出的散热器设计结合了改善热性能的几何形状，但难以用传统方法生产，使其成为增材制造的理想选择。散热器与传统的纵向板翅散热器模型进行了比较，传热系数为0.159 W/K。性能最好的散热器模型达到了0.184 W/K的传热系数，表明增材制造的被动式散热器可以为全封闭的非通风机器提供显着改善的冷却。

Analysis of Advanced Passive Heatsinks For Electrical Machines Enabled by Additive Manufacturing

This paper presents numerical models of several different natural convection based heatsink designs for an additively manufactured switched reluctance machine. The proposed heatsink designs incorporate geometries that have improved thermal performance but are difficult to produce with conventional methods, making them ideal options for additive manufacturing. The heatsinks are compared to a traditional longitudinal plate fin heatsink model with a heat transfer coefficient of 0.159 W/K. The highest performing proposed heatsink model achieves a heat transfer coefficient of 0.184 W/K, showing that additively manufactured passive heatsinks can provide significantly improved cooling for totally enclosed non-ventilated machines.
