Low-voltage comprehensive distribution box body

The utility model discloses a low-voltage comprehensive distribution box body. The problems that an existing distribution box body is poor in heat dissipation effect, difficult to meet the requirement of the protection level and prone to deformation are mainly solved. The radiator is characterized in that the left side wall (3) and the right side wall (4) are each of a hollow double-layer structure composed of an outer side plate (7) and an inner side plate (8), and a heat dissipation channel (9) is formed between each outer side plate (7) and the corresponding inner side plate (8); the top cover (6) comprises a top cover plate (12) and a top cover inner partition plate (13), the top cover plate (12) and the top cover inner partition plate (13) form a double-layer hollow structure with an inverted (U)-shaped section, and heat dissipation holes (15) are formed in the bottom of a folded edge (14). The left side wall, the right side wall and the top cover are all of a hollow double-layer structure, a heat dissip
