Stable heat dissipation type capacitor

The utility model discloses a stable heat dissipation type capacitor comprising a heat dissipation assembly, and the heat dissipation assembly comprises a capacitor core, a capacitor outer shell, a capacitor inner shell, a pin, a top cover, a first spring, a pressing plate, a heat conduction column, a heat conduction sheet, a second spring and a heat dissipation sheet. And a capacitor inner shell is arranged on the inner bottom wall of the capacitor outer shell. According to the utility model, the first spring is compressed by closing the top cover, the elastic force of the first spring pushes the pressing plate to press the inner shell of the capacitor, and the second spring pushes the heat-conducting sheet to clamp and fix the inner shell of the capacitor in the horizontal direction, so that the structural stability after the inner shell of the capacitor and the capacitor core are installed is improved; the heat-conducting fins are always attached to the surface of the inner shell of the capacitor under the
