随着对MC-WPT系统性能要求的提高，如果温度过高，大功率电能传输MC-WPT的耦合机构或功率转换电路的温度可能会改变甚至损坏系统。温度控制已成为大功率MC-WPT系统长期稳定的关键。因此，本文提出了一种层隙耦合机制的损耗优化结构。首先，我们以动力传递性能为切入点，设计了一种能够在耦合机构尺寸限制下传递高输出功率的耦合机构；其次，分析了耦合机构损耗发热的机理和优化方法；最后，我们从改善散热结构和减少损耗产生的热量方面对耦合机构的热性能进行了优化。
As the performance requirements of MC-WPT systems increase, the temperature of the coupling mechanism or the power conversion circuit of a high-power power transmission MC-WPT system can change or even damage the system if the temperature is too high. The control of the temperature has become the key to the long-term stability of high-power MC-WPT systems. Therefore, this paper proposes a loss optimization structure for the coupling mechanism with layer gaps. Firstly, we take the power transmission performance as the entry point to design a coupling mechanism that can transmit high output power under the size limitation of the coupling mechanism; secondly, we analyze the mechanism and optimization method of heat generation due to losses in the coupling mechanism; finally, we optimize the thermal performance of the coupling mechanism in terms of improving the heat dissipation structure and reducing the heat generation due to losses.
