In this work, an innovative aluminum liquid cold plate for press-pack power applications with an internal finned geometry made with additive manufacturing is proposed and analyzed. Thermal and fluid dynamic performances are estimated by FEM simulations, which have been validated through an ad hoc test bench. Proper considerations about potential problems of the selective laser melting metal printing technique and their implications for the reliability of liquid cold plates have been done. Then, simulation results for failure conditions (short circuit and coolant liquid circuit failure cases) on a complete press-pack stack are shown.

FEM 模拟应用于大功率压装应用的 3D 可打印翅片液体冷板的失效分析

在这项工作中，提出并分析了一种用于压装电源应用的创新铝液冷板，其内部翅片几何形状由增材制造制成。热力和流体动力学性能通过 FEM 模拟进行估计，并通过临时测试台进行了验证。已经对选择性激光熔化金属印刷技术的潜在问题及其对液体冷板可靠性的影响进行了适当的考虑。然后，显示了完整压装堆上的故障条件（短路和冷却液回路故障情况）的仿真结果。
