A numerical study has investigated the thermal performance and economic viability of a latent heat thermal energy storage (LHTES) unit equipped with inclined fins. This type of system is crucial for improving the efficiency of renewable energies, such as solar, by allowing excess heat to be stored for later use. The research focused on optimizing the fin configuration to maximize the thermal charging and discharging rate, a key factor in the effectiveness of these devices.

The analysis considered parameters such as fin inclination, length, and number of fins, evaluating their impact on heat transfer within the phase change material (PCM). The numerical results provided a detailed understanding of how these geometric modifications influence the melting and solidification time of the PCM, which in turn affects the capacity for thermal energy storage and release. Optimizing these systems is fundamental for their integration into practical applications, from building climate control to industrial processes.

In addition to thermal performance, the study addressed the economic viability of the proposed configuration. This included a cost analysis associated with the manufacturing and installation of LHTES units with inclined fins, comparing them with the benefits obtained in terms of energy savings and emission reductions. The research aims to offer guidelines for the design of more efficient and cost-effective LHTES systems, accelerating their adoption in the energy sector.
