The utility model discloses a link up aluminium foil for aluminium electrolytic capacitor is applied to aluminium electrolytic capacitor, and the aluminium foil has the perforating hole, and the electrolyte conducts, and heat dispersion is good, and resistant ripple characteristic is better than current aluminium foil, has improved aluminium electrolytic capacitor's capacity.
Description
Technical field
The utility model relates to aluminium foil production technical field, specifically a kind of through aluminium foil for aluminium electrolytic capacitor.
Background technology
Electrolytic capacitor is one of indispensable components and parts in electronic product.Along with the fast development of electronic technology, packaging density and the integration degree of complete electronic set increase further, aluminium electrolytic capacitor as key, the discrete component of not accessible site, just towards small size, Large Copacity, low cost, low impedance at high frequency future development.Aluminium electrolytic capacitor have function admirable, Large Copacity, cheap, be easy to processing, the feature such as easy to use, be therefore widely used in the electronic system products such as information electronic device, instrument, electromechanics, household electrical appliances.And as produce aluminium electrolytic capacitor critical material---the domestic and international production technology of aluminium foil also achieves the development of advancing by leaps and bounds in recent years, properties of product improve constantly.
Domestic aluminium foil for electrolytic capacitor industry, although the support obtaining the plan of national " 863 " new and high technology, " 973 " plan, the scientific and technological plan of electronic information venture capital and local government at front 1O, also achieves great successes.Cubic texture content Absorbable organic halogens as aluminium foil for high-voltage anode controls, more than 95, to reach international most advanced level.But this just solves the research and development of the Some Key Technologies difficult point in capacitor industry development.The aluminium foil for high-voltage anode with high cubic texture can not meet the demand of user completely, also need the distribution of the surface state to aluminium foil, crudy and trace element and existence to carry out deep research, the adaptability problem of aluminium foil for high-voltage anode to etching process system could be solved.
Therefore this series products combination property and to the adaptability of etching process obviously can not meet aluminum current electrolytic capacitor produce needs.
Utility model content
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art, solves the technological deficiency existed at present, the utility model discloses a kind of through aluminium foil for aluminium electrolytic capacitor.
The technical scheme that the utility model adopts is:
For the through aluminium foil of aluminium electrolytic capacitor, described aluminium foil comprises sandwich of layers and alundum (Al2O3) layer, and described sandwich of layers both sides are fitted with alundum (Al2O3) layer, and the thickness of described aluminium foil is 100um, and described aluminium foil has multiple from the through through hole to the back side in paper tinsel surface.
Further, the aperture of described through hole is 3 ~ 5um.
Further, the density of described through hole is 5% ~ 8%, and the aluminium foil of this density through hole applies on aluminium electrolytic capacitor, and electrolyte conducts is good, has simultaneously and specifically has very high specific volume.
The beneficial effects of the utility model are,
A kind of through aluminium foil for aluminium electrolytic capacitor disclosed in the utility model,
Be applied to aluminium electrolytic capacitor, aluminium foil is anode foils, and aluminium foil has through hole, and electrolyte conducts is good, perfect heat-dissipating, and resistance to ripple characteristics is better than existing aluminium foil, improves the capacity of aluminium electrolytic capacitor.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1, alundum (Al2O3) layer 2, sandwich of layers 3, through hole.
Embodiment
In order to deepen, to understanding of the present utility model, to be described in further detail the utility model below in conjunction with drawings and Examples.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection range of the present utility model with this.
As shown in Figure 1, for the through aluminium foil of aluminium electrolytic capacitor, aluminium foil comprises sandwich of layers 2 and alundum (Al2O3) layer 1, sandwich of layers 2 both sides are fitted with alundum (Al2O3) layer 1, the thickness of aluminium foil is 100um, aluminium foil has multiple from the through through hole 3 to the back side in paper tinsel surface, and the aperture of through hole 3 is 3 ~ 5um, and the density of through hole 3 is 5% ~ 8%.
Through aluminium foil of the present utility model is for changing into anode foils, for aluminium electrolytic capacitor, alundum (Al2O3) layer is withstand voltage insulating barrier, realize the mobile of electric charge to store, aluminium foil has through hole, and electrolyte conducts is good, perfect heat-dissipating, resistance to ripple characteristics is better than existing aluminium foil, improves the capacity of aluminium electrolytic capacitor.
Be noted that, the above embodiment is unrestricted to the explanation of technical solutions of the utility model, the equivalent replacement of art those of ordinary skill or other amendments made according to prior art, as long as do not exceed thinking and the scope of technical solutions of the utility model, all should be included within the interest field required by the utility model.
