Abstract
The utility model discloses an aluminium electrolytic capacitor convenient for heat radiation; the aluminium electrolytic capacitor comprises an aluminium cylinder and a capacitor core bag; the capacitor core bag comprises an anode aluminium foil, a cathode aluminium foil, an anode guide line, a cathode guide line and at least three electrolytic paper layers arranged between the anode aluminium foil and the cathode aluminium foil; the anode guide line and the cathode guide line are riveted with corresponding the anode aluminium foil and the cathode aluminium foil through fixed tongue portions; a width of the electrolytic paper is bigger than that of the cathode aluminium foil; and a width of the anode aluminium foil is bigger than that of the electrolytic paper. The anode guide line and the cathode guide line are respectively arranged departing from the electrolytic papers; an electrolytic paper layer formed by stacking at least three electrolytic paper layers can ensure a sufficient thickness, so that burrs generated in riveting process cannot penetrate the electrolytic paper layer, and disadvantages of capacitor short circuit breakdown and even explosion caused by the burrs are prevented; and an exposed portion of the anode aluminium foil can fast radiate the heat, so electrolyte is effectively prevented from being dried. The aluminium electrolytic capacitor convenient for heat radiation is stable in structure, good in heat radiation effect, and long in service life.
Description
Technical field
The utility model relates to the capacitor technology field, relates in particular to a kind of aluminium electrolytic capacitor of being convenient to dispel the heat.
Background technology
As a kind of important capacitance component, aluminium electrolytic capacitor has been widely used in the electron trade; Wherein, aluminium electrolytic capacitor has generally comprised anodal aluminium foil, negative pole aluminium foil, electrolytic paper, positive wire and negative wire.
In the aluminium electrolytic capacitor process of manufacture, positive wire and negative wire riveting are loaded on corresponding anodal aluminium foil and negative pole aluminium foil, electrolytic paper is installed between anodal aluminium foil and the negative pole aluminium foil, owing to be easy to produce burr phenomena during the riveting dress, in the process that anodal aluminium foil, electrolytic paper and negative pole aluminium foil are reeled together, burr may occur and pierce through electrolytic paper or the burr tip defectives such as causing capacitor short-circuit puncture, blast of under electric field action, discharging.
In addition, for avoid anodal aluminium foil and negative pole aluminium foil in winding process owing to contacting the phenomenon that is short-circuited, the width of the general more anodal aluminium foil of the width of the electrolytic paper of existing aluminium electrolytic capacitor, negative pole aluminium foil is big; Because aluminium electrolytic capacitor can produce heat in the course of work of reality, too much accumulation of heat can cause electrolyte to be caused aluminium electrolytic capacitor to lose efficacy by oven dry; Yet there is the heat radiation defect of bad in said structure, has seriously influenced the useful life of aluminium electrolytic capacitor.
Summary of the invention
The purpose of this utility model is to provide a kind of aluminium electrolytic capacitor of being convenient to dispel the heat, aluminium electrolytic capacitor Stability Analysis of Structures, good heat dissipation effect and long service life that this is convenient to dispel the heat at the deficiencies in the prior art.
For achieving the above object, the utility model is achieved through the following technical solutions.
A kind of aluminium electrolytic capacitor of being convenient to dispel the heat, it is characterized in that: include the aluminium cylinder and be flush-mounted in the interior capacitor core bag of aluminium cylinder, the capacitor core bag includes anodal aluminium foil and negative pole aluminium foil, be equiped with at least three layers of electrolytic paper between anodal aluminium foil and the negative pole aluminium foil, positive wire is equipped with in anodal aluminium foil riveting, negative wire is equipped with in the riveting of negative pole aluminium foil, positive wire and negative wire are respectively arranged with fixedly tongue, fixedly tongue is riveted with corresponding anodal aluminium foil and negative pole aluminium foil respectively, the fixedly tongue of positive wire is positioned at anodal aluminium foil and deviates from electrolytic paper one side, and the fixedly tongue of negative wire is positioned at the negative pole aluminium foil and deviates from electrolytic paper one side; The width of electrolytic paper is big than the width of negative pole aluminium foil, and the width of anodal aluminium foil is big than the width of electrolytic paper.
The beneficial effects of the utility model are: a kind of aluminium electrolytic capacitor of being convenient to dispel the heat described in the utility model, it includes the aluminium cylinder and is flush-mounted in the interior capacitor core bag of aluminium cylinder, the capacitor core bag includes anodal aluminium foil and negative pole aluminium foil, be equiped with at least three layers of electrolytic paper between anodal aluminium foil and the negative pole aluminium foil, positive wire is equipped with in anodal aluminium foil riveting, negative wire is equipped with in the riveting of negative pole aluminium foil, positive wire and negative wire are respectively arranged with fixedly tongue, fixedly tongue is riveted with corresponding anodal aluminium foil and negative pole aluminium foil respectively, the fixedly tongue of positive wire is positioned at anodal aluminium foil and deviates from electrolytic paper one side, and the fixedly tongue of negative wire is positioned at the negative pole aluminium foil and deviates from electrolytic paper one side; The width of electrolytic paper is big than the width of negative pole aluminium foil, and the width of anodal aluminium foil is big than the width of electrolytic paper.Positive wire of the present utility model and negative wire deviate from electrolytic paper respectively and install, and the electrolysis ply of paper of at least three layers of electrolytic paper stack can guarantee enough thickness, and the burr of being produced during riveted joint can not pierce through the electrolysis ply of paper and can not produce because defectives such as caused capacitor short-circuit puncture of burr even blasts; In addition,, be exposed to the outer anodal aluminium foil part of electrolytic paper and apace the heat of capacitor core bag dispelled the heat away, and then avoided thermal accumlation effectively and the defective that causes electrolyte to be dried because the heat-conducting effect of aluminium foil is well more a lot of than electrolytic paper.Comprehensive above-mentioned situation the utlity model has the advantage of Stability Analysis of Structures, good heat dissipation effect and long service life as can be known.
