【摘要】：熔融盐是一种非常有前景的高温液体传热蓄热工质,在太阳能热发电、余热回收及工业热利用方面有显著的优势,但是熔融盐本身存在导热性能不高等问题。本文对纳米复合相变材料固液相变储能过程的若干最新研究进行了回顾,综述了熔融盐纳米固液相变复合材料国内外研究现状及发展趋势,最后对纳米复合相变材料固液相变储能过程的未来发展和重点研究方向进行了展望,认为主要解决纳米复合材料内熔化相变传热双温度模型的建立及求解、NC-PCM的制备工艺、金属纳米粒子的团聚性及NC-PCM蓄热器的热循环实验等方面的问题是未来研究的重点。
[Abstract]:Molten salt is a promising high temperature liquid heat transfer and thermal storage medium, which has obvious advantages in solar thermal power generation, waste heat recovery and industrial heat utilization. However, the molten salt itself has some problems such as low thermal conductivity and so on. In this paper, some recent researches on the solid-liquid phase change energy storage process of nano-composite phase change materials are reviewed, and the research status and development trend of molten salt nano-solid liquid phase change composites at home and abroad are reviewed. Finally, the future development and research direction of solid-liquid phase change energy storage process of nano-composite phase change materials are prospected. It is considered that the main solution is to establish a dual-temperature model of heat transfer in nanocomposites and to solve the preparation process of NC-PCM. The agglomeration of metal nanoparticles and the thermal cycle experiment of NC-PCM accumulator are the key points of future research.
