: A key factor for increasing the life of electronic devices and preventing early failure is the implementation of thermal management techniques. In thermal management, phase change materials (PCMs) are generally used. There have been a few studies conducted on PCM stability. Using thermal cycle tests, PCM (RT 42)-based energy storage systems with and without pin fins were evaluated for thermal stability. The material used for the pin fins and the heat sink was Aluminum 2024-T851. During the thermal cycle tests, the PCM-based heat sinks at 10 W had a maximum temperature difference of 1.088 °C. This leads to the PCM-based heat sink being stable during charging and discharging. According to the results of the thermal cycle tests conducted on the PCM and triangular pin-fin-based heat sink, the maximum temperature difference between the tests was 0.58 °C at 10 W. Based on the results, the PCM triangular pin-fin heat sink is stable during charging and discharging.
