This study aims to enhance the heat transfer efficiency of phase change heat exchangers by modifying conventional straight fins. Three fin structures (triangular, wavy, and square) were designed, along with three levels of eccentricity (10 mm, 15 mm, and 20 mm).
The performance of a latent heat storage unit comprised of phase change material (PCM) enclosed in a finned-tube heat exchanger was evaluated experimentally and theoretically to determine its viability to condition a space during summer.
Abstract An experimental study is conducted in order to investigate melting and solidification processes of paraffin RT35 as phase change materials in a finned-tube. Therefore the effect of using fins in this study as well as some operational parameters is considered.
This complex geometry is difficult and hence expensive to construct. This paper proposes a multiple-scale 3D finite element modeling approach to design fin-tube HXs for low-cost latent thermal energy storage applications.

This work presents the design and experimental results of a finned tube heat exchanger to store collected natural thermal energy from a building envelope in a latent-based TES and to release it later for building heating/cooling applications.
The three-tube phase change thermal storage structure offers a significant advantage over the single-tube structure due to its larger heat transfer area per unit length and higher overall flow rate in the annular area, thereby enhancing the heat exchanger''s heat exchange efficiency.
cal model of the fin-tube phase-change energy storage heat exchanger. In this model, the PCM is used to fill the adjacent fins, and the heat transfer fluid flows into the middle heat exchange tube from top to bottom and exchanges heat
ORNL has developed a new thermal energy storage design utilizing low conductivity organic phase change materials. The new design offers low costs along with charge/discharge times appropriate for building thermal mass—even when there is a small temperature difference between the heat transfer fluid and the material''s phase change temperature.
