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影响。结果表明，渐缩结构较其它结构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（0.2s），此时平行板、波纹及渐缩AER制冷量分别为4.16W、4.35W及4.71W，COP分别为1.77、2.04及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0.68W增至10.06W，提升约14.79倍。
Abstract
The optimization of regenerator geometries to enhance the performance of active electrocaloric regenerators (AER) has drawn significant attention. In this study
corrugated and tapered structures were applied to a parallel-plate AER
and the effects of electric field parameters on device performance were comparatively analyzed. The results indicate that the tapered structure better balances flow resistance and heat transfer efficiency
demonstrating the best refrigeration performance under the same operating conditions
followed by the corrugated AER structure. Excessively short or long device cycle periods resulted in poor refrigeration performance. Switching the electric field is an optimal choice when the heat transfer reaches 63%-66% of the maximum possible heat transfer. For the same cycle period
each device exhibited an optimal polarization duration (0.2s)
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 COPs of 1.77
2.04
and 3.17. As the electric field strength increases
the refrigeration capacity of the device increases exponentially. The larger the field strength
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 rose from 0.68 W to 10.06 W
an improvement of approximately 14.79 times.
