In this paper, the use of the heat pipe technology to enhance the use of PCMs in energy storage is investigated experimentally. This is done by testing the option of combining the latent heat thermal energy storage heat exchanger with a finned and multi-legged heat pipe.

The entire thermal energy storage unit is initially at T in = 613 K which is 5 K higher than the melting temperature of PCM.This means that all PCM is in liquid phase at the beginning. The discharging process starts at τ = 0 s by extracting a constant and uniform heat flux of 40 kW/m 2 through the bottom surface of the container, Fig. 1.

Percentage of battery shaped used in all BTMS based on heat pipes publications within 2018–2023. Fig. 10 shows the number of papers published between 2018 and 2023 based on the type of heat pipe used in the paper. It can be seen that flat heat pipe ( FHP) is the most used heat pipe type in the studies of BTMS.
