Heat sinks are often used in electronic devices to dissipate heat energy away, cooling down the devices to moderate temperature. Heat sink fins are made of heat conductive metals and applied on high temperature device absorbing its heat energy and then emit to ambience via radiation and convection. Though the most common daily application of heat sink which might come into our minds only is on the CPU of personal computer along with fan and thermal paste, it is also proven to be useful in dealing with overheat process medium of instrumental device.
