Section VII – Mechanical Section
The heat sink allows the amplifiers to operate at a cooler temperature and prevents overheating,
which helps the longevity of the entire system. The heat sink has hollow fins, which help dissipate
the heat from the amplifiers faster than a conventional serrated or corrugated fin.
In addition to the cooling effects of the heat sink, within the 500-watt power amplifier enclosure,
there are four fans that each provide 170 cubic feet per minute (CFM) of air flow (into zero static
pressure). There are two fans mounted at the front of the heat sink and two mounted at the back
end of the heat sink. The fans are mounted side-by-side to produce the best cooling for the system
and are operating in a push-pull configuration to assist with heat dissipation. The fans are a 24Vdc
variety, so there are series dropping resistors to drop the higher power supply voltage down to a
safe level.
