Welding structure of sulfur hexafluoride heat dissipation cavity

The utility model provides a welding structure of a sulfur hexafluoride heat dissipation cavity. The welding structure comprises a welding frame. A plurality of radiating windows for fixing radiating fins are arranged on the top surface, the bottom surface and the two side surfaces of the welding frame; the length and the width of the heat dissipation window are smaller than those of the heat dissipation fins; heat dissipation fins are densely arranged on the two surfaces of the heat dissipation sheet; the radiating fins cover the radiating window and are combined with the welding structure through welding to form a sulfur hexafluoride radiating cavity; the radiating fins on one side of the radiating fin are exposed on the outer wall of the sulfur hexafluoride radiating cavity, and the radiating fins on the other side of the radiating fin extend into the space of the sulfur hexafluoride radiating cavity; according to the utility model, the sulfur hexafluoride radiator can be manufactured in a welding manner,
