Outdoor power distribution cabinet

The invention provides an outdoor power distribution cabinet, and relates to the technical field of power distribution cabinets. An outdoor power distribution cabinet comprises a power distribution cabinet shell which is provided with an air inlet and an air outlet, and a plurality of supporting plates used for fixedly installing electrical elements are arranged in the power distribution cabinet shell; the air inlet fan is used for extracting air outside the power distribution cabinet shell, so that the air can cool electrical elements in the power distribution cabinet shell to form high-temperature airflow; an air outlet fan; expansion and contraction liquid is stored in the material storage shell, the expansion and contraction liquid can expand with heat and contract with cold along with temperature change, and the expansion and contraction liquid is heated to enable the air outlet fan to exhaust high-temperature airflow out of the power distribution cabinet shell; and the driving mechanism can drive the ai
