Effects of melting temperature and the presence of internal fins on the performance of a phase change material (PCM)-based heat sink

Experimental investigation on the thermal performance of a heat sink filled with porous metal fiber sintered felt/paraffin composite phase change material

“…This phenomenon could be observed at other input powers. The duration for which the undershoot was observed become shorter as the input power increased, indicating that floating paraffin melts faster under more intensive natural convection in liquid paraffin because of the increasing heating power [37]. For the heat sink with MF-PCM, T1 MF-PCM decreased to a lower level than T1 paraffin owing to the introduction of high-conductivity PMFSF.…”

Multi-objective geometric optimization of a PCM based matrix type composite heat sink

“…Fan et al [17] experimentally investigated the effect of internal fins on the performance of the PCM based heat sinks. For the purpose of baseline comparison, an unfinned heat sink was taken and it was concluded that use of a PCM could keep the device temperature under safe operating limits.…”

Multiple Phase Change Material (PCM) Configuration for PCM-Based Heat Sinks—An Experimental Study

“…It was first proposed for avionics thermal control in 1977 [15] and since then a lot of studies investigated the PCM-based heat sink [16][17][18][19][20][21][22][23][24]. The main drawback of the PCM is its low conductivity which has led researchers to propose various enhancement techniques such as using extended surfaces of different configurations [25][26][27][28], employing multiple PCMs [29] and PCM encapsulation [30].…”

“…Fan et al [26] investigated the importance of selection of the PCM melting temperature in a horizontal heat sink arrangement with a heating source ranged between 60 to 120 W. The used PCMs were eircosane and hexadecanol. The study showed that a longer thermal regulation period (the duration for which the heat sink is maintained at low temperature) is achieved when using a higher melting temperature of PCM.…”
