“…Second, the initiation of the PCM melting occurs later as the fins become thicker. This behavior was first observed by Hosseinizadeh et al (2011) for PCM-based plate fin heat sinks. Their results showed that this property is related to the mode of heat transfer in the PCM, and heat is mainly transferred by conduction.…”

“…The convergence is checked at each time step, with the convergence criterion of 10 −6 for the continuity equation, 10 −5 for the momentum equation and 10 −8 for the energy equation. In order to validate the melting computational model in our finite-volume CFD code, initial runs were performed and compared with experimental data of Hosseinizadeh et al (2011). As can be seen from Fig.…”

“…Akhilesh et al (2005) directed a numerical investigation to develop a thermal design procedure that maximizes the operating time of a composite heat sink which is made up of an elemental heat sink, PCM and high-conductivity base material. Hosseinizadeh et al (2011) reported a parametric study on a plate fin PCM-based heat sink and found that increasing the number of fins and their height results in a considerable increase in overall thermal performance, whereas increasing the fins' thickness only brings about a slight improvement. Baby and Balaji (2012) compared the heat transfer performance of a plate fin heat sink with that of a pin fin heat sink in an experimental study.…”

Abstract. This paper presents a numerical investigation in which thermal performance characteristics of pin fin heat sinks enhanced with phase-change materials (PCMs) designed for cooling of electronic devices are studied. The paraffin RT44 HC is poured into the aluminum pin fin heat sink container, which is chosen for its high thermal conductivity. The effects of different geometrical parameters, including number, thickness and height of fins, on performance are analyzed. Different aspects for heat transfer calculation, including the volume expansion in phase transition as well as natural convection in a fluid zone, are considered in the study. In order to validate the numerical model, previous experimental data and the present results are compared, and an acceptable agreement between these two is observed. Results show that increasing the number, thickness and height of fins leads to a significant decrease in the base temperature as well as operating time of the heat sink.
