Nor, again, that of a bad man passing from adversity to prosperity: for nothing can be more alien to the spirit of Tragedy; it possesses no single tragic quality; it neither satisfies the moral sense nor calls forth pity or fear.
A heat sink (also commonly spelled heatsink) is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of the device's temperature at optimal levels.
Aside from the finning factor, the heat sink porosity has a secondary effect on the pin fin performance. The comparison among three orientations shifts in favour of upward and sideward arrangements with raising the heat sink porosity in consequence of reducing the flow resistance.
