Purpose - the purpose of this paper is to investigate efficient designs of a shell-and-tube latent thermal energy storage system through an approach based on the analysis of entropy generation it proposes innovative branched fins to maximize the performance of the system. A heat exchanger for use, eg, in a rear door of a server rack in a computer room, made up of pipes clad with a layer of a phase change material, such as a paraffin, so that latent heat is absorbed in the conversion from the solid to the liquid state. Thermal performance of the latent heat storage unit many indicate a significant enhancement in the system performance melting in a triplex tube heat. Increased melting heat transfer in the latent heat energy storage from the tube-and-shell model to the combine-and-shell model.
