| Summary: | 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. |
