摘要：
A composite heat sink is one in which a phase change material is interspersed with a high thermal conductivity base material to maximize the thermal performance of the device. Unlike constant area fins considered in literature, this work considers a repeating elemental composite heat sink (ECHS) with variable area fins. The base material is aluminium and the phase change material is n-Eicosane. An in house code was developed in MATLAB© to determine the time of operation for a vertical fins ECHS for a one dimensional approximation. This was followed by a two dimensional analysis of the problem using FLUENT 6.3. The effects of the shape of the interface surface on the time of operation and overall heat dissipated are determined and design modifications for the composite Heat Sinks based on the results obtained are suggested.
