摘要

磁耦合器是IPT系统实现高效能量传输的关键部件。磁耦合器在运行过程中的热损耗导致线圈温度升高，影响IPT系统的运行稳定性。本文建立了该耦合器的电路和磁场模型。研究了联轴器中线圈、铁芯和铝屏蔽板的发热机理。并给出了运行30min后各部件的温度分布。测量了耦合器各部分的温升，线圈温度最高。通过对磁力耦合器的热场仿真，可以优化磁力耦合器在无线电力传输系统运行过程中各部分的温升。

Research on Temperature Rise and Heat Dissipation of Wireless Power Transfer

The magnetic coupler is a crucial part of the IPT system to achieve high-efficiency energy transmission. The heating loss of the magnetic coupler during operation causes the coil's temperature to rise, affecting the IPT system's operational stability. In this paper, the circuit and magnetic field model of the coupler are established. The heating mechanism of the coil, iron core and aluminum shielding plate in the coupler is studied. Furthermore, the temperature distribution of each component is given after running for 30 minutes. The temperature rise of each part of the coupler was measured, and the coil temperature was the highest. Through the thermal field simulation of the magnetic coupler, the temperature rise of each part of the magnetic coupler in the operation of the wireless power transmission system can be optimized.
