摘　　要：本文将高导热材料添加到供液腔中以降低传热阻力,并对工质脱气来降低跨膜传质阻力。这些措施显著提高了热渗透能量转换系统的效率,单级TOEC系统的实验水通量达到56.69 L·m^(-2)·h^(-1)。本文还建立了预测系统性能的理论计算模型,结果表明:34级系统在加热和冷却温度分别为80℃和40℃时的峰值运行效率为4.03%,相应的功率密度为27.56 W·m^(-2)。本研究为提升TOEC系统的效率提供了一种行之有效的方法。This study investigates integrating high thermal conductivity materials into the liquid chamber to decrease heat transfer resistance and examine the impact of fluid-degassing on the transmembrane resistance.These measures enhanced the efficiency of thermo-osmotic energy conversion(TOEC)system and the experimental water flux of a single-stage TOEC system reaches an attractive value of 56.69 L·m^(-2)·h^(-1).Furthermore,a theoretical model was built to forecast the performance.The results showed that a 34-stage system attained a maximum efficiency of 4.03%and a corresponding power density of 27.56 W·m^(-2)at heating and cooling temperatures of 80℃ and 40℃,respectively.This study exhibits a feasible approach for enhancing the efficiency of TOEC system.
