主 题：Thermal conduction multilayer structure electrocaloric effect heat pump
摘 要：The analytical solution is reported for one-dimensional(1D)dynamic conduction heat transfer within a mulilayer system that is the typical structure of electrocaloric ***,the multilayer structure of typical electrocaloric devices is simplified as four layers in which two layers of electrocaloric materials(ECMs)are sandwiched between two semi infinite bodies representing the thermal sink and *** temperature of electrocaloric layers can be instantaneously changed by extemal electic field to establish the initial temperature *** analytical solution includes the temperatures in four bodies as a function of both time and location and heat flux through each of the three interfaces as a function of *** of these analytical solutions includes five infinite *** is proved that each of these series is convergent so that the sum of each series can be calculated using the first N terms of the *** formula for calculating the value of N is presented so that the simulation of an electrocaloric device,such as the temperature distribution and heat transferred from one body to another can be *** value of N is dependent on the thickness of electrocaloric material layers,the time of heat conduction,and thermal properties of the materials *** on a case study,it is concluded that the N is mostly less than 20 and barely reaches more than *** application of the analytical solutions for the simulation of real electrocaloric devices is discussed.
