Capacitor

Abstract

The invention relates to a capacitor which comprises an electrode outer frame, wherein a first electrode plate is arranged on one side inside the electrode outer frame, and a second electrode plate isarranged on the other side inside the electrode outer frame; a first electric contact is arranged on one side at the upper end of the first electrode plate; a second electric contact is arranged on the other side of the second electrode plate; a capacitor core is arranged between the first electrode plate and the second electrode plate; insulating layers are arranged on outer sides of the first electrode plate and the second electrode plate; sealed end covers are arranged on two sides of the electrode outer frame; and a plurality of cooling fins are arranged on the outer side of the electrodeouter frame along a horizontal direction. Under the actions of the first electric contact and the second electric contact, good electrical connection between a conductive metal plate and the outer frame is ensured, and a heat transfer path is increased, so that heat inside the capacitor capable of realizing rapid heat dissipation can be rapidly conducted out, and a rapid heat dissipation effect is achieved.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a capacitor. Background technique [0002] Capacitors, usually referred to as capacitance for their ability to hold charges, are denoted by the letter C. Definition 1: Capacitors that can achieve rapid heat dissipation, as the name implies, are 'capacitors for charging electricity' and are devices that hold charges. English name: capacitor. Capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control, etc. in circuits. Definition 2: Capacitor, any two conductors (including wires) that are insulated from each other and are very close to each other form a capacitor. Capacitors are not the same as capacitors that allow rapid heat dissipation. Capacitance is a basic physical quantity, the symbol C, and the unit is F (farad). [0003] Cap...

AI Technical Summary

Problems solved by technology

However, because the heat dissipation effect is not good enough, the capacitor is prone to thermal aging under long-term high temperature conditions, which seriously affects the practical life of the capacitor. Therefore, the heat dissipation problem of the capacitor has attracted more and more attention.
