The invention discloses an intelligent heat dissipation system of a high-low voltage power distribution cabinet, which comprises a heat dissipation device and an intelligent control end and relates to the technical field of power distribution cabinets. This high-low voltage power distribution. an efficient heat dissipation power distribution cabinet for smart gridsincluding a power distribution cabinet, both sides of the power distribution cabinet are rotatably connected with bolt plates, and the upper surface of the power distribution cabinet A card slot is provided, and the RG-1002HT. Guizhou Detai Electric Co. is a leading source factory in China with 20 years of experience in sheet metal manufacturing, certified with CE, UL, and ISO9001 Quality Management System. We specialize in distribution boxes, distribution cabinets, and custom non-standard sheet metal products. see Figure 1 to Figure 4, the present invention provides a technical solution: an intelligent distribution box for efficient heat dissipation, the intelligent distribution box for efficient heat dissipation includes: a rear box body 1, the inner wall of the rear box body 1 is provided with. At present, the common heat dissipation method of the distribution box is to open cooling holes on the box body, and use natural ventilation to achieve heat exchange. However, due to the rainproof effect, the cooling holes are generally are relatively few and small, which leads to poor heat.
