摘要/Abstract

摘要： 物质在物相变化过程中由环境吸收热量或冷量,也可以向环境放出热量或冷量,以实现能量储存和释放.固-液相变储能过程具有较大的承压能力.利用海洋温差能驱动的水下滑翔机工作在几百米深的海水中,承受巨大的外界海水压力,选用固-液相变材料作为感温工质-储能材料,可以保证相变储能动力系统稳定可靠地工作.利用固-液相变储能机理运行的水下机器人即水下滑翔机,不需要自带能源而吸取海洋温差能获得驱动力.本文阐述相变储能机理,回顾相变储能研究的发展.以赤道附近海域为例,以水下热滑翔机相变换热管为分析对象,说明了固-液相变储能过程在水下运载器驱动上的应用.

Abstract: Phase change materials take/release thermal energy from/to the environment during liquid-solid phase change whereby energy is stored and released. Such a solid-liquid phase change process is capable of withstanding a high pressure. This provides an opportunity for driving underwater gliders working below hundreds of meters of sea surface. The thermal underwater gliders use ocean thermal energy, hence preventing the needs for carrying power sources. The paper explains the mechanism of phase change energy storage,and reviews research and development of phase change energy storage. The example for the phase change processes inside the tube proves the application on driving underwater glider.

Key words: underwater vehicle, solid-liquid phase change, energy storage
