| 摘要: |
| 大容量海上风电机组在整体布局中通常将变流器安装于机舱内，其中电抗器需要考虑高效合理的冷却方案以解决高功率密度引发的散热问题。提出一种新型相变冷却方案，以提高散热性能，实现电抗器功率密度的提升。以一台电感为1 mH的电抗器为例，分析了电抗器的电磁和散热结构特点，设计了相变冷却系统，并利用多目标遗传算法进行电抗器参数优化设计。基于优化设计方案建立了三维温度场仿真模型，获得了相变冷却电抗器的温度分布特征。对比结果表明，所提优化设计方案可使电抗器总质量和体积分别减小15.4 %和17.9 %。基于相变冷却电抗器线圈温升实验平台，验证了相变冷却系统的散热性能，以及所提电抗器轻量化方案的可行性。 |

| Abstract: |
| In the overall layout of large-capacity offshore wind turbines, converters are typically installed within the nacelle. For the reactors, the efficient and rational cooling solutions must be considered to address heat dissipation issues caused by high power density. A novel phase-change cooling solution is proposed to enhance heat dissipation performance and achieve the increased power density in reactors. Taking a 1 mH reactor as an example, the electromagnetic and heat dissipation structural characteristics of the reactor are analyzed, a phase-change cooling system is designed, and the optimized design of reactor parameters is performed using a multi-objective genetic algorithm. Based on the optimized design scheme, a three-dimensional temperature field simulation model is established to obtain the temperature distribution characteristics of the phase-change cooling reactor. The comparison results demonstrate that the optimized design scheme can reduce the total mass and volume of the reactor by 15.4 % and 17.9 %,respectively. Based on the experimental platform of phase-change cooling reactor coils, the heat dissipation performance of the phase-change cooling system and the feasibility of the proposed lightweight solution of the reactor are validated. |
