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.
