“…Therefore, it is necessary to deploy methods, which would enhance heat transfer in the LHTESS. The heat transfer enhancement can be achieved by increasing the thermal conductivity of the PCM by means of adding high thermal conductive particles and placing high thermal conductivity inserts into the PCM such as metallic fins or combination of different methods [20,21]. One of the approaches considered in the project was the use of reversible heat pipes in [17,18] combination with metallic inserts.…”

The design of the latent heat thermal storage system (LHTESS) was developed with a thermal capacity of about 100 kW h as a part of small solar plant based on the organic Rankine cycle (ORC). The phase change material (PCM) used is solar salt with the melting/solidification temperature of about 220 °C. Thermophysical properties of the PCM were measured, including its phase transition temperature, heat of fusion, specific heat, and thermal conductivity. The design of the thermal storage was finalized by means of the 3D computational fluid dynamics analysis. The thermal storage system is modular, and the thermal energy is delivered with the use of thermal oil, heated by Fresnel mirrors. The heat is transferred into and from the PCM in the casing using bidirectional heat pipes, filled with water. A set of metallic screens are installed in the box with the pitch of 8–10 mm to enhance the heat transfer from heat pipes to the PCM and vice-versa during the charging and discharging processes, which take about 4 h. This work presents a numerical study on the use of metallic fins without thermal bonding as a heat transfer enhancement method for the solar salt LHTESS. The results show that the absence of the thermal bonding between fins and heat pipes (there was a gap of 0.5 mm between them) did not result in a significant reduction of charging or discharging periods. As expected, aluminum fins provide better performance in comparison with steel ones due to the difference in the material conductivity. The main advantage observed for the case of using aluminum fins was the lower temperature gradient across the LHTESS.

The performance of an electric vehicle depends on the battery used. While, in the operation of an electric vehicle, batteries experience a quick heating especially at the beginning of charging and could cause a fire. Therefore, the solution could be proposed is by employing heat pipe and Phase Change Material (PCM) for cooling of battery. The heat pipe serves to transfer the battery’s heat energy. In other hands, PCM functions as a heat sink when the battery runs, so its performance will stable and extend the lifespan. This study aimed to evaluate the performance of electric vehicle batteries at a temperature of 50°C using the combination of heat pipe and PCM. The ‘L’ type of heat pipe and beeswax PCM were assembled as cooling device. In addition, a battery simulator was employed as a test instrument by varying the heat load of 20, 30, 40, and 50 W. The experiments were successfully conducted, and the results showed that the addition of heat pipe and PCM could keep the surface temperature of battery below 50°C, at heat load of 20 - 50 W. Heat pipe and PCM for battery’s cooling system, can reduce the battery surface temperature significantly and can be proposed as an alternative system for cooling battery.

“…A variety of thermal management techniques and designs have been widely investigated in the literature, including air cooling (natural or forced air convection) [5][6][7][8][9], liquid cooling [10][11][12][13][14], heat pipe cooling [15][16][17] and phase change materials (PCM) cooling system [18][19][20][21][22]. Natural air cooling technology is suffering from low cooling efficiency, which failed to meet the requirement for the increasing power output of the electrical vehicle [23].…”
