Abstract: An outdoor electric cabinet and an air duct structure thereof are provided. The air duct structure is used to guide airflow to an air inlet side of a fan. The air duct structure includes an air inlet port, a flow-guiding cavity and an air distribution assembly. The air inlet port is configured to introduce external airflow into the air duct structure. The flow-guiding cavity is formed between the air inlet port and the air inlet side of the fan. The air distribution assembly is arranged in the flow-guiding cavity to uniformly distribute an air suction force of the air inlet port. The airflow suction force at the air inlet port is distributed more uniformly by the air distribution assembly, which effectively weakens the maximum wind speed on the shortest path.
