Abstract

The invention discloses an aluminum electrolytic capacitor with life extension and open circuit prevention and belongs to the technical field of electrolytic capacitors. The aluminum electrolytic capacitor with life extension and open circuit prevention comprises an element, an aluminum shell and an aluminum cover. The element is covered by an aluminum shell and an aluminum cover to form an aluminum electrolytic capacitor body, and an outer side of the aluminum shell is equipped with a heat-dissipating explosion-proof outer casing formed by a base and a sleeve. When the device is used, excessends of lengthened positive and negative lead strips and rivets are connected by ultrasonic welding, therefore, the contact between the rivets and foil lead strips is effectively strengthened, and theopen circuit formed by corrosion due to the long-time use of the foil lead strips is prevented. When the device is overheated, a fan on the base rotate to allow the device to dissipate heat, a hollowcopper tube and a heat conductive film mounted on a cover plate contained in the sleeve can further improve heat dissipation efficiency, and therefore, the heat dissipating performance and the explosion-proof performance of a product are improved.

Description

technical field [0001] The invention relates to the technical field of electrolytic capacitors, in particular to an aluminum electrolytic capacitor that prolongs the service life and prevents open circuits. Background technique [0002] As the three major electronic components, aluminum electrolytic capacitors are widely used in inverters, inverters, UPS power supplies, industrial power supplies, photovoltaics and other industries, mainly for energy storage, filtering and bypassing. [0003] Specifically, aluminum electrolytic capacitors generally adopt a foil winding structure with two electrodes, the positive electrode is mainly a positive foil, the negative electrode is an electrolyte, and the medium is an aluminum oxide film on the surface of the positive foil. They form the basic structure of aluminum electrolytic capacitors. [0004] Aluminum electrolytic capacitors mainly include the following structures: combined figure 1 As shown, the structure is called core, whi...
