Cooling - AE Techron LVC 5050 Quick Start Manual

Cooling

NEVER block the air vents in the front or back of the amplifier. These
amplifiers DO NOT need to be mounted with space between them. If
you must leave open spaces in a rack for any reason, close them with
blank panels or poor airflow will result. Allow for airflow of at least 75
cubic feet (2.1 cubic meters) per minute per unit. Additional airflow
may be required when driving low-impedance loads at consistently
high output levels.
NOTE: Refer to Section 3 Applications for detailed information on
thermal dissipation.
When mounting the amplifier in a rack cabinet, the back wall of the
rack should be at least 3 inches (7.6 cm) away from the back of the
amplifier chassis as shown below.
If your rack has a door, provide adequate airflow by installing a grille
in the door or by pressurizing the air behind the door. Wire grilles are
recommended over perforated panels. A good choice for pressurizing
the air behind the rack cabinet door is to mount a "squirrel cage"
blower inside the rack (Option 1 above). Mount the blower so it blows
outside air into the space between the door and front of the amplifiers,
pressurizing the "chimney" behind the door. This blower should not
blow air into or take air out of the space behind the amplifiers.
