Usage of phase change materials’ (PCMs) latent heat has been investigated as a promising method for thermal energy storage applications. However, one of the most common disadvantages of using latent heat thermal energy storage (LHTES) is the low thermal conductivity of PCMs. This issue affects the rate of energy storage (charging/discharging) in PCMs. Many researchers have proposed different methods to cope with this problem in thermal energy storage. In this paper, a tubular heat pipe as a super heat conductor to increase the charging/discharging rate was investigated. The temperature of PCM, liquid fraction observations, and charging and discharging rates are reported. Heat pipe effectiveness was defined and used to quantify the relative performance of heat pipe-assisted PCM storage systems. Both experimental and numerical investigations were performed to determine the efficiency of the system in thermal storage enhancement. The proposed system in the charging/discharging process significantly improved the energy transfer between a water bath and the PCM in the working temperature range of 50 °C to 70 °C.

“…Low thermal conductivity, slow heat storage and release rates limit the practical applications of PCMs. Therefore, intensive investigations have been carried out to improve the thermal conductivity of PCMs [13][14][15][16][17]. Li et al [18] mixed the expanded graphite (EG) with capric acid (DA) to prepare a capric acid / expanded graphite composite phase change material (DA/EG-PCMS) with high stability and good thermal conductivity, the thermal conductivity of composites increased with the increase of expanded graphite.…”

In order to obtain phase change materials with suitable melting point, latent heat and thermal conductivity, this paper employed the liquid paraffin with a melting point of 17°C and solid paraffin with a melting point of 41°C in different proportions to fabricate PCM composites. By adjusting the mixing ratio of short-chain hydrocarbons and long-chain hydrocarbons in paraffin wax, phase change materials with different phase change ranges were obtained to meet the requirements of practical applications. A variety of copper foam /paraffin composite phase change materials with different porosities and pore densities were prepared by the melt dipping method. The influence of the porosity and pore density on the thermal conductivity of copper foam/paraffin composite was explored. The experimental results show that mixed paraffin can control the melting point and latent heat of composite phase change materials. Copper foam can greatly increase the thermal conductivity of composite phase change materials with the porosity has a greater impact and the pore density has a less effect. The thermal conductivity of composites can be increased by a maximum 20 times.
