Radiating shell structure of electronic device

The utility model provides a heat-sinking shell of electric equipment, which comprises an input component, an output component and a printed circuit board. The printed circuit board is connected with the input component and the output component. The heat-sinking shell comprises an extruded metal shell comprising at least four surfaces to form a space for the printed circuit board, a first opening and a second opening, a first side plate with a mounting hole for the input component which is used to cover the first opening of the extruded metal shell, a second side plate with a mounting hole for the output component which is used to cover the second opening of extruded metal shell. The utility model can dissipate heat generated by the electronic component on the PCB or stabilize the temperature of the electric equipment through the extruded metal shell.
