[0002] The function of UPS (uninterruptible power supply) system is to provide temporary power when the main power fails to ensure the continuous operation of key equipment such as servers and medical equipment. In UPS power cabinet, since the power devices generate a lot of heat during operation, if the heat is not dissipated in time, it will cause the equipment to overheat, affect the performance, and even damage the equipment. At present, the common heat dissipation methods of UPS power cabinets include natural convection and fan forced convection, which have certain limitations in heat dissipation efficiency and maintenance difficulty. Utility Model Content

[0005] In the above scheme, the first heat dissipation component and the second heat dissipation component can accelerate the air flow, thereby playing a role in heat dissipation inside the cabinet. The first heat dissipation duct and the second heat dissipation duct are formed in the cabinet through the connection of the connecting plate, the partition and the baffle.

The design of the second cooling air duct helps to guide the airflow directly through the radiator, thereby more effectively removing the heat. The rectifier module and the inverter module are in different cooling air ducts from the transformer module, thereby improving the overall cooling efficiency of the cabinet.

[0016] Furthermore, it also includes a plurality of front door panels, which are located on one side of the rectifier module and the inverter module, and the front door panels are provided with ventilation holes.

[0017] In the above scheme, the ventilation holes allow air to flow, which helps to improve the heat dissipation efficiency, and the ventilation holes on the front door panel increase the heat dissipation area, which helps to more effectively dissipate the heat generated by the rectifier and inverter modules.

[0018] The utility model provides a UPS power cabinet heat dissipation device with the beneficial effects of improving heat dissipation efficiency, ensuring the stability of the UPS power cabinet and facilitating maintenance. The first heat dissipation component and the second heat dissipation component can accelerate air flow, thereby playing a role in heat dissipation inside the cabinet.
