[0002] In the power distribution system, the distribution cabinet is usually used to centrally control multiple working equipment, which results in a large number of electrical components and complex circuits inside the distribution cabinet. Multiple working equipment will cause a large load on the distribution cabinet during long-term use, causing the internal electrical components and cable conductors to generate a lot of heat, so a distribution cabinet with good heat dissipation is required. This type of distribution cabinet can refer to patent number: 202321319397.1.

[0003] Generally, a power distribution cabinet only has a small number of fans installed inside for heat dissipation, and has no function of cooling the outside of the power distribution cabinet. During peak hours, if there is no internal and external coordination for heat dissipation, the required requirements may not be met, which will have a certain impact on the normal operation of the electrical components in the cabinet. Therefore, a power distribution cabinet that can coordinate internal and external heat dissipation is needed. Utility Model Content
