摘要：The present invention relates to a heat dissipation system for a communicationdevice with a box type chassis, a box type chassis, and a communication device with a boxtype chassis. The heat dissipation system includes an upper heat dissipation channel and alower heat dissipation channel, where the upper heat dissipation channel and the lowerheat dissipation channel both have an air exhaust vent and an air intake vent, the air intakevent and the air exhaust vent of the upper heat dissipation channel and the lower heatdissipation channel are defined on sidewalls of the box type chassis, and the air intake

vent of the upper heat dissipation channel is located above the air exhaust vent of thelower heat dissipation channel. An air baffle is arranged in the box type chassis togenerate a circulative airflow in the box type chassis, and therefore, heat dissipated by acircuit board is circulated in the box type chassis through the airflow, the temperature inthe box type chassis reaches an extent that prevents vapor from condensing or evenbecoming a water film, occurrence of condensation or water film is prevented, and thecircuit board is protected against corrosion caused by condensation.
