2.3 Heat Dissipation System
The heat dissipation system is responsible for the heat dissipation of the entire device. Heat
generated by the boards is dissipated through the heat dissipation system. In this manner, the
temperatures of the components on the boards are controlled within a normal range, enabling
the boards to work properly. The heat dissipation system is composed of a fan frame, an air
intake vent, an air exhaust vent, and an air channel. All the fans in the fan frame work
simultaneously, and their rotation speeds can be adjusted by area. When one fan fails, the heat
dissipation system can still allow the device to work at an ambient temperature of 40°C (104°
F) for a short period. The temperature sensors, which are located on the air exhaust vent and
boards, monitor the temperatures of the components on the boards and adjust the fan rotation
speeds according to the commands delivered by the MPU to control the board temperatures.
