| 摘要: |
Thermal energy storage (TES) can be achieved with latent heat storage systems using phase change materials (PCMs). It has been used in a wide of application including solar energy storage and electronic device thermal management. However, the problem involved so far with conventional PCMs has been their very low thermal conductivity. To increase the heat transfer ability of the PCM, a heat transfer intensifier is necessary for the TES system. Recently, compressed expanded natural graphite (CENG) is under investigation as a thermal enhancer and a container in PCMs due to their high thermal conductivity, low density, and chemical inertness. The composite materials allow highly efficient, compact and dynamic thermal energy storage systems that provide energy at a constant temperature level. Wood's alloy is employed as a PCM since it presents high thermal conductivity, high latent heat, and good chemical stability. Nevertheless, few papers are devoted to study the thermal properties of CENG infiltrated with Wood's alloy as a TES system. In the present work, Wood's alloy is infiltrated into the CENG in an attempt to enhance the thermal conductivity of the alloy. As an important factor of a TES system, thermal properties of the composite have been characterized. Effects of the thermal performance of the CENG on the composite have been discussed. |
