Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet body with adjustable heat dissipation channels. Background Art

[0002] A distribution cabinet is a device used for the distribution, control and protection of electric energy. It is used to supply electric energy to various electrical equipment and systems. It is usually composed of one or more electrical compartments. Today's distribution cabinets are relatively closed and have limited internal space. Long-term full-load operation of electrical equipment will lead to heat accumulation and temperature rise. In addition, the components inside the distribution cabinet will generate heat when powered on, especially in summer, which will cause further temperature rise in the distribution cabinet. At the same time, the self-heating of the components and the temperature rise in the cabinet may cause tripping.

[0003] The prior art discloses a heat-dissipating outdoor power distribution cabinet with an adjustable top opening area, application number 202310471423.0. The cabinet comprises a cabinet body, an air inlet opening on one side and a gas outlet opening on the top. The cabinet body is also provided with a shielding member to prevent rainwater from falling into the gas outlet opening. The cabinet body also comprises a liquid inlet opening on the top of the cabinet body, and an adjustable valve provided on the top of the cabinet body, the adjustable valve being located above the liquid inlet. In this heat-dissipating outdoor power distribution cabinet with an adjustable top opening area, liquid is directed from the cabinet body to the outside of the cabinet body via a flow guide assembly. This fluid exhibits a countercurrent gradient on the surface of the object, i.e., generates a negative hydrostatic pressure, thereby generating a negative pressure in the surrounding air. This in turn drives the gas inside the cabinet body to be discharged, achieving a circulating flow of the gas inside the cabinet body and preventing rainwater from being drawn into the cabinet body. However, the cabinet body is not convenient for adjusting the opening and size of the sidewall heat dissipation channel, which affects the flexibility of heat dissipation. Utility Model Content
