Abstract
Heat sinks (HSs) are designed for the mechanical, electrical and electronic components that generate heat in considerable amount. For this purpose, an aluminum conical pin fin heat sink is designed. Aluminum conical pin-fins geometry has been experimentally investigated for the blowing direction (pushing or pulling) which is the energy efficient option for the heat sink. The heat sink was tested at the same fan power for pushing and pulling conditions for 25, 50, 75 and 100 W resistance heater power. Designed aluminum conical pin fin heat sink can be easily used in heat sweeping processes. It has found that pushing configuration of the fan is more efficient for this design.
Highlights
Mechanical, electrical and electronic components generate heat in considerable amount
The fan was run at the same electrical values and the fan orientation was reversed for to change the blowing direction
The air velocity in the pushing mode was twice as high, which can be explained by the fin density of the Heat sinks (HSs)
Summary
Mechanical, electrical and electronic components generate heat in considerable amount. Ahamed et al [2] studied porous conical pin fin array under natural convection conditions and the experimental results showed that heat transfer coefficient, fin efficiency, and effectiveness were increased up to 5.16, 7.39 and 22.19% respectively than that of non-porous pin fin for the same power. The experimental setup consisted of the air duct, fan, heat sink, plate type resistance heater, insulation, fire brick and test instruments.
