The aluminum electrolytic capacitor has the functions of storing energy and filtering ripples in the power supply in the switching power supply, and the aluminum electrolytic capacitor can be caused to generate heat when the aluminum electrolytic capacitor works by superposing ripple current due to the existence of Equivalent Series Resistance (ESR) inside the aluminum electrolytic capacitor, so that the service life of the aluminum electrolytic capacitor is influenced. The larger the ripple current in the power supply is, the more serious the internal heating of the aluminum electrolytic capacitor is, and the shorter the service life is.

The existing rubber plug can only be used for sealing the electrolytic capacitor and is penetrated by positive and negative leads. In this case, a novel rubber plug for sealing an electrolytic capacitor, which facilitates heat dissipation, is proposed in combination with the problem of heat generation of the electrolytic capacitor.
