瞬态热电器件作为一种很有前景的能量转换技术，在温度控制和制冷领域具有潜在的应用前景。性能对所施加的电流脉冲敏感。然而，传统的电流脉冲仅限于规则的电流形状，无法实现最佳的过冷性能。脉冲形状、脉冲幅度、脉冲宽度等参数之间存在较强的耦合效应。同时优化电流脉冲中涉及的所有变量是进一步改善过冷的先决条件。为了弥补这一差距，本研究提出了无约束电流脉冲设计概念，并通过多目标优化方法成功验证。结果表明，优化后的有效冷却方式和温度超调均表现出优异的特性。与当前的t0（以前的研究中主要采用的）相比，有效冷却方式和温度超调分别提高了88.33％和92.13％。基础物理学表明，波状不规则电流脉冲在珀耳帖冷却、焦耳加热和傅里叶传导效应之间的适当调节是造成这种改善的原因。优化电流形状中发现的帕累托最优前沿有利于科学家和工程师针对具体的实际应用做出适当的决策。
As a promising energy conversion technology, transient thermoelectric device has potential applications in temperature control and refrigeration. The performance is sensitive to the applied current pulse. However, the conventional current pulse is limited to regular current shapes, which cannot achieve the best super-cooling performance. There exist strong coupling effects between the parameters of pulse shape, pulse amplitude, and pulse width. Simultaneous optimization of all the variables involved in a current pulse is a prerequisite to further improve the super-cooling. To bridge this gap, a constraint-free current pulse design concept was proposed in this study, which was successfully validated by a multi-objective optimization method. The results show that, the effective cooling regime and temperature overshoot both exhibit excellent features after optimization. Compared with the currentt0(mostly employed in previous studies), the betterments are improved by 88.33% and 92.13% for the effective cooling regime and the temperature overshoot, respectively. The underlying physics reveals that, the appropriate mediation between Peltier cooling, Joule heating, and Fourier conduction effects by a wave-like irregular current pulse is responsible for the improvement. The Pareto-optimal front found in the optimized current shape is beneficial for scientists and engineers to make an appropriate decision towards specific practical application.
