Ducted Flow Cooling

Here is an unfortunate fact: Generating power creates heat. As

ZAPCO has learned to put more power into a smaller package, the

management of thermal properties has become increasingly important.

The Reference Digital chassis has our new Ducted Flow Cooling.

Cool air is brought into the chassis from the forward vents. The air travels

over the components and is then forced down a duct flowing over the heat

sink. The heated air is then exhausted through vents at the end of the heat

sink.

In the higher power units where cooling is a bigger problem a fan

located over the sink increases air flow for more cooling.

A problem which has plagued fan cooling for years is the noise of

the fan. The fan itself generates a degree of mechanical noise and the air

motion itself causes a degree of noise (like wind noise). The Ducted Flow

system attacks both these problems.

First, the fan is mounted inside the amp, in the middle, so the amp

itself acts as a muffler to keep mechanical noise trapped inside. Second,

because the fan is not located near the vents we can eliminate the “wind

noise” of pulling the air through the vents.

The result: The Ducted Flow chassis gives superior convection

cooling without the usual fan noise. This means better sound and reliability.
