Anti-explosion aluminum capacitor

Abstract

The invention discloses an anti-explosion aluminum capacitor. The anti-explosion aluminum capacitor comprises a capacitor body, wherein a negative electrode wiring terminal and a positive electrode wiring terminal are connected above the capacitor body; both the negative electrode wiring terminal and the positive electrode wiring terminal are in sleeve joint with protection gaskets; the capacitorbody is in sleeve joint with a cooling shell; the cooling shell body is provided with cooling fins; a capacitor core is arranged inside the capacitor body; the surface of the capacitor core is in sleeve joint with a capacitor shell; an upper end cover plate is arranged at a top end of the capacitor core; the space between the upper end cover plate and the capacitor core is filled with a collapsible encapsulation material; the capacitor core is connected with a fuse through a first connection wire; and the other end of the fuse is connected with the positive electrode wiring terminal through afirst connection wire. According to the anti-explosion aluminum capacitor, the cooling shell and the cooling fins are provided, so that the capacitor body can be heated and cooled rapidly; the coolingspeed of the aluminum electrolytic capacitor is increased; and the service life thereof is prolonged.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to explosion-proof aluminum capacitors. Background technique [0002] Aluminum electrolytic capacitors are energy storage components used in circuits for tuning, filtering, coupling, bypassing, energy conversion, and time delay. Aluminum electrolytic capacitors are usually called capacitors. According to its structure, it can be divided into three types: fixed capacitor, semi-variable capacitor and variable capacitor. Aluminum electrolytic capacitor is a general-purpose electrolytic capacitor made of aluminum material with good electrical performance, wide application range and high reliability. [0003] At present, some aluminum electrolytic capacitors on the market have poor heat dissipation effect, and are prone to heat during use, resulting in failure or damage of the capacitor, and even expansion of the capacitor, thereby causing safety accidents.
