Using phase change material in heat sinks to cool electronics devices with intermittent usage

As the temperature of electronic devices increases, their failure rate increases. That's why electrical devices should be cooled. One of the promising cooling techniques is using Phase Change Materials (PCMs). PCMs are potential temperature regulators that store and release thermal energy during the process of melting and freezing respectively. PCM-based heat sinks can effectively store the heat dissipated from the electronic components to delay the peak temperature of the electronic devices as much as possible and then release the stored energy during the off period. This paper compares the temperature distribution on a heat sink with and without PCM with different heat flux.
