摘要

优化回热器几何形状以提高主动回热式电卡制冷（AER）器件的性能受到人们广泛关注，本文将波纹及渐缩结构用于平行板，对比分析了电场参数对器件性能的影响。结果表明：渐缩结构较其他结构可以更好地平衡流动阻力与传热效率，在相同工况下表现出最佳制冷性能，波纹AER次之。器件循环周期过短或过长，均导致制冷性能不佳，传热量达到最大可能传热量的63%~66%时切换电场是较佳的选择；同一循环周期下，器件均存在最佳极化时长（0.2 s），此时平行板、波纹及渐缩AER制冷量分别为4.16、4.35、4.71 W，COP分别为1.76、2.04、3.17。随场强增加，器件制冷量均呈指数型增大，场强越大，渐缩AER制冷量提升越大，场强由50 MV/m增至225 MV/m时，渐缩AER制冷量由0.68 W增至10.06 W，提升约13.79倍。

Abstract

The optimization of regenerator geometries to enhance the performance of active electrocaloric regenerators （AERs） has attracted significant attention. In this study， corrugated and tapered structures were applied to a parallel-plate AER， and the effects of electrical field parameters on device performance were compared. The results indicated that the tapered structure better balanced the flow resistance and heat transfer efficiency， thus achieving the best refrigeration performance under the same operating conditions， followed by the corrugated AER structure. Short or long device cycle periods resulted in poor refrigeration performance. The electrical field should be switched when the transferred heat reaches 63%-66% of its maximum value. For the same cycle period， each device exhibited an optimal polarization duration （0.2 s）， during which the refrigeration capacities of the parallel-plate， corrugated， and tapered AERs were 4.16 W， 4.35 W， and 4.71 W， respectively， with corresponding coefficients of performance of 1.76， 2.04， and 3.17. As the electrical field intensity increases， the refrigeration capacity of the device increases exponentially. The greater the field intensity， the greater the improvement in the refrigeration capacity of the gradually shrinking AER. When the field intensity increased from 50 MV/m to 225 MV/m， the refrigeration capacity of the tapered AER increased from 0.68 W to 10.06 W， an improvement of approximately 13.79 times.
