Abstract: An outdoor cabinet is disclosed and includes a cabinet, an active damper and a passive damper. The cabinet includes an air inlet, an air outlet and an accommodation space. The accommodation space is in communication with an outdoor environment through the air inlet and the air outlet, respectively. The active damper is arranged adjacent to the air inlet. The passive damper includes an exhaust fan and a damper blade. The exhaust fan is arranged adjacent to the air outlet. The damper blade is arranged between the air outlet and the outdoor environment. When the exhaust fan is in operation, the damper blade allows a heat-dissipation airflow to be discharged from the air outlet to the outdoor environment. When a wind pressure of the outdoor environment is greater than a wind pressure of the accommodation space, the damper blade closes the air outlet to protect electronic devices installed in the cabinet.
