Experimental and Simulation Research on Reciprocating Flexible Film Electrocaloric Device
摘要
Abstract
Based on ferroelectric polymers,electrocaloric cooling technology has potential application advantages in scenarios such as wearables,portable devices,and distributed thermal management.In this study,a highly efficient and compact reciprocating flexible film electrocaloric device is constructed,using ferroelectric polymers P(VDF-TrFE-CFE)as the electrocaloric material,achieving a temperature span(Tspan)of 1.6 K.To further improve the device's cooling performance,a one-dimensional simulation platform is developed,and the reliability of the simulation model is validated based on experimental results.Through simulation calculations,the influence of various design parameters on the Tspan,cooling power density,and performance coefficient of the device is discussed.The results indicate that,by optimizing operating strategies and material properties,the electrocaloric device can achieve a maximum cooling power density of 3 039 mW/cm2 under a Tspan of 3 K.关键词
