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.
When selecting a heat sink for a forced convection application fin orientation is very important. If the air is flowing in a single direction, then orienting the fins in the direction of air flow provides the best heat sink thermal performance. Additionally, the heat sink fin design plays a significant role in the heat sinkâs effectiveness. Figure 2 illustrates two fin design options for standard horizontal heat sinks. In each case the fin creates a channel for the air to flow through. The design shown in Figure 2(b) is more effective than the design of Figure 2(a) because the channel length is minimized. Figure 2. Heat Sink Fin Orientation Selecting a Heat Sink Heat sinks are rated based on the amount of heat they can dissipate. Heat sink manufacturer data sheets provide thermal resistances for natural convection and various air flow velocities, as shown in the Figure 3 example. The natural convection curve is given in temperature rise
