ABSTRACT
Heat
sinks were invented to absorb heat from an electronic circuit conduct,
and then to dissipate or radiate this heat to the surrounding
supposedly, ventilated space, at a rate equal to or faster than that of
its buildup. Ventilation was not initially recognized as an essential
factor to thermal dispersion. However, as electronic circuit-boards
continued to heat up, circuit failure became a problem, forcing the
inclusion of miniaturized high speed fans. Later, heat sinks with fins
and quiet fans were incorporated in most manufactured circuits. Now heat
sinks come in the form of a fan with fans made to function as fins to
disperse heat. Heat sinks absorb and radiate excess heat from
circuit-boards in order to prolong the circuit’s life span. The higher
the thermal conductivity of the material used the more efficient and
effective the heat sink is. This paper is an attempt to theoretically
design a heat sink with a temperature gradient lower than that of the
circuit board’s excess heat.
