1. Industrial Control Cabinets: Equipment with internal heating components such as PLCs and frequency converters. Ventilation holes enable air convection for heat dissipation, preventing component aging due to high temperatures.
2. Outdoor Distribution Boxes: In high-temperature or direct sunlight environments, they help dissipate heat generated by the operation of internal electrical components, maintaining a stable working temperature.
3. Data Communication Equipment Cabinets: Cabinets used for installing network devices such as routers and switches. Ventilation holes cooperate with fans to form heat dissipation channels, ensuring continuous operation of the equipment.
4. Motor Control Boxes: The control devices driving motors generate a lot of heat during operation. Ventilation holes can effectively reduce the temperature inside the box and avoid frequent triggering of motor overload protection.
