| description | The invention discloses an electronic equipment metal shell with a blackened surface. An internal heat dissipation efficiency improvement scheme of an existing packaging shell needs to be improved. The inner surfaces and the outer surfaces of an upper metal shell and a lower metal shell are subjected to blackening treatment; the top of the outer surface of the upper metal shell is provided with a plurality of rectangular radiating fins subjected to blackening treatment, and the top of the inner surface of the upper metal shell is provided with a plurality of trapezoidal radiating fins subjected to blackening treatment; and a plurality of triangular radiating fins subjected to blackening treatment are arranged on the inner surfaces of the upper metal shell and the lower metal shell and on the side surfaces parallel to the trapezoidal radiating fins. By blackening the inner and outer surfaces of the upper metal shell and the lower metal shell, the surface emissivity is improved, and the heat dissipation effect |
