Abstract: In this numerical study, we want to present the design
of highly efficient extruded-type heat sink. The symmetrically
arranged extruded-type heat sinks are used instead of a single extruded
or swaged-type heat sink. In this parametric study, the maximum
temperatures, the base temperatures between heaters, and the heat
release rates were investigated with respect to the arrangements of heat
sources, air flow rates, and amounts of heat input. Based on the results
we believe that the use of both side of heat sink is to be much better for
release the heat than the use of single side. Also from the results, it is
believed that the symmetric arrangement of heat sources is
recommended to achieve a higher heat transfer from the heat sink.
