The satellite terminal trailer system involves removing the satellite terminal from a military vehicle and installing it on a flat-deck trailer. With an auxiliary fuel tank in place, the system can run for a full day on generator power. As part of a mechanical subsystem, exhaust fans are used to remove generator exhaust from the trailer. The exhaust fans require a power-conversion systemthe satellite terminal power boxto allow the fans to operate on the available power. To determine the thermal behavior of the satellite terminal power box, constraints must be set on the internal temperatures, the thermal budget must be determined, and the thermal resistance network analyzed. The natural convection and conduction of the power box is determined, and an exhaust fan is sized to remove excess heat.
