1.3.5 Heat Dissipation System
This section describes the air channel features of the heat dissipation system and the
appearance, functions, and technical specifications of fan modules.
1.3.5.1 System Air Channel
This section describes the system air channels and air flows of the USG9520.
The USG9520 draws air from the left side and exhausts air from the rear. The air intake vent
is located at the left side of the chassis, and the air exhaust vent is located at the rear of the
chassis. The air filter covers a large area and has a curved face and low windage resistance,
improving heat dissipation efficiency.
The system draws in air for heat dissipation in the DC and AC chassis, as shown in
, respectively.
