Convex tendon contact on the inside of housing bottom；Positive pole weld tabs on insulation cover plate is affixed with positive outside wire by aluminium rivet.Should
Design beneficial effect is：By shelling machine into the muscle of weld tabs and bottom containing projection on the basis of traditional structure, and extend
The length of anode foil lower end, the negative pole lower end for the capacitor body for making to be wound into tubular structure are stretched out and raised with outer casing bottom
Muscle be in close contact；Therefore heat can by the outside Quick diffusing of shell, significantly reduce the temperature of capacitor internal.Obviously
The design radiates only by shell, and its radiating effect is not ideal enough.
Utility model content：
Technical problem to be solved in the utility model is to overcome existing technological deficiency, there is provided a kind of storage capacitor
Device.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of energy-storage capacitor, including it is fixed in the housing by cathode foil, anode foil and by the cathode foil and negative pole
The electrolytic paper of paper tinsel isolation is wound into the capacitor body of tubular structure, and the insulation cover plate of the housing port closed is fixed on
The positive pole weld tabs that is connected on the insulation cover plate and by positive outside wire with the cathode foil and it is fixed on the insulation cover plate
And the negative pole weld tabs being connected by negative outside wire with the anode foil, the lower end of the anode foil are longer than the lower end of electrolytic paper,
The housing bottom surface has the groove for accommodating anode foil, and housing bottom is located at groove floor and is additionally provided with longitudinal radiating fin, dissipates
Some through holes are provided with hot fin, lower housing portion side wall is provided with some fresh air inlets and exhaust vent.
The heat-conducting silicone grease around anode foil is perfused with the groove.
