[0002] Power automation equipment refers to equipment that uses modern information technology and electronic technology to automatically control and manage power systems. It plays an increasingly important role in power systems. It can improve the safety, stability and reliability of power systems, and also improve the monitoring and control capabilities of power grid operation. Power automation equipment is often installed in equipment boxes to protect the power automation equipment. Due to the small internal space of the equipment box, airflow is not circulated. The equipment box is usually equipped with a cooling fan to dissipate the temperature of the power equipment during operation.

[0003] At present, when the equipment box of the power automation equipment uses fans to dissipate heat, the heat generated by the power automation equipment in the equipment box during operation often cannot be discharged due to the relatively simple layout of the cooling fans in the equipment box. Especially in some high temperature seasons, the power automation equipment is prone to overheating and failure in the equipment box, thereby affecting the normal operation of the power automation equipment. To this end, this paper proposes a heat dissipation device for power automation equipment. Utility Model Content
