Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically to a louvered heat dissipation structure for a distribution box. Background Technology

[0002] Distribution boxes are characterized by their small size, easy installation, special technical performance, fixed location, unique configuration functions, lack of site restrictions, wide application, stable and reliable operation, high space utilization, small footprint, and environmental benefits. They serve as the control center for the rational distribution of electrical energy among various components in the power supply line, a control link for reliably receiving power from upstream sources and correctly feeding power to the load, and are also key to obtaining user satisfaction with power supply quality. Improving the operational reliability of power distribution boxes is a goal of creating high-quality projects.

[0003] To ensure good heat dissipation in distribution boxes, most systems use louvers for ventilation. Existing technology, such as Chinese patent CN215718332U, discloses a louver device for distribution boxes, relating to the field of louver technology. The device includes: a louvered panel, a waterproof baffle with ventilation function, and a drip tray. The waterproof baffle is located inside the louvered panel, and the drip tray is located below the waterproof baffle and connected to the louvered panel. The lowest louver opening on the louvered panel is connected to the drip tray.

[0004] For example, Chinese patent CN215927196U, entitled "A Hollow Louver for Partitions with Protective Structure," discloses a hollow louver for partitions with a protective structure, including a frame. A louver body is hinged to the inside of the frame, and protective magnetic plates are snapped onto the upper and lower sides of the front of the louver body. Limiting baffles are fixedly connected to the upper and lower surfaces of the inner wall of the frame.

[0005] Such patents can effectively block splashing solid particles and rainwater from the outside and autonomously discharge them, thus ensuring the insulation of the electrical components inside the enclosure to a certain extent. However, in actual installation, multiple people are needed to facilitate the installation of the distribution cabinet. Furthermore, the louvers are located on the outside of the distribution box, which is inconvenient for transportation and also affects the aesthetics of the distribution box, presenting certain shortcomings.
