Thermal management is one of the challenging areas in the view of shrinking devices size requiring efficient cooling to take care of the thermal load. The shrinking size of devices require efficient cooling for thermal load balance capabilities. This complicated requirement can be fulfilled with the help of Thermal Energy Storage (TES) systems. Phase Change Material (PCM) is one of the best examples of TES system. This paper deals with experimental investigation on Chevron Plate Heat Exchanger (CPHE) filled with an organic PCM PureTemp 29. PCM offers efficient performance in storing and releasing large quantities of thermal energy at any given temperature. Water is used as a Heat Transfer Fluid. The melting of PCM also known as discharging is studied at 5, 8 and 10 GPH. The flow of hot water at 38 °C and 32 °C through CPHE leads to melting of PCM known as discharging process. While, the flow of cold water at 20 °C and 26°C respectively through CPHE leads to solidification of PCM known as charging process. Load capacity and thermal efficiency of the PCM has been discussed in order to provide and estimation for future design modifications and efficiency enhancement of heat exchangers.
