We use a physical model to optimize the mechanical and magnetic properties of a magneto-thermoelectric generator (MTG) device to improve its performance. The key to the MTG device designed for thermal energy harvesting is the use of the ferromagnetic–paramagnetic transition of Gd metal induced by a temperature difference between two heat sources. To increase the heat transfer between the Gd and the heat sources, a clamped and simply supported beam structure is proposed as an alternative to cantilevers. For the mechanical and magnetic optimization of the proposed structure, a physics model is used to develop theoretical predictions. Experiments confirmed that the MTG device operates within the predicted range.

我们使用物理模型来优化磁热电发电机（MTG）设备的机械和磁性能，以改善其性能。设计用于热能收集的MTG装置的关键是利用由两个热源之间的温差引起的Gd金属的铁磁-顺磁转变。为了增加Gd与热源之间的热传递，提出了一种夹紧且简单支撑的梁结构作为悬臂的替代方案。为了对所提出的结构进行机械和磁优化，将使用物理模型来发展理论预测。实验证实，MTG设备可在预期范围内运行。
