Description
Technical field
The present invention relates to a kind of capacitor, particularly aluminium electrolutic capacitor.
Background technology
Aluminium electrolutic capacitor, also known as electric capacity, are a kind of energy-storage travelling wave tubes, and its structure can be divided into fixed capacity device, half can power transformation
Three kinds of container, variable condenser, its feature are that capacity is big, but it is big to leak electricity, and error is big, and stability is poor, and it is other to be commonly used for exchange
Road and filtering, are also used for signal coupling when less demanding, and electrochemical capacitor has a point of positive and negative electrode, can not be reversed during use.It is
Negative pole is done by aluminium cylinder, the inside is equipped with liquid electrolyte, and the aluminium strip for inserting a piece of bending does positive pole and manufactured capacitor, is referred to as
Aluminium electrolutic capacitor.
At present, the operating temperature range of existing high pressure (more than 500WV) aluminium electrolutic capacitor is -25 DEG C~105 DEG C,
Play energy storage, filtering etc. in electronic circuit.But when this kind of capacitor works in less than -25 DEG C environment temperatures, its electric capacity
Amount can acutely decline, and it is in resistive to make capacitor, loses its due capacitive, not have the effect such as energy storage, filtering.In recent years,
With the fast development of solar energy, wind energy etc., electronics are widely used in high and cold, High aititude occasion, building ring
Border is increasingly complicated, and particularly operating ambient temperature requirement extend to -55 DEG C~125 DEG C, even more extensively, traditional aluminium electroloysis electricity
Container can not be applicable the new demand of this operating temperature range, can not especially be applied to the field that working environment is less than -25 DEG C
Close.
The content of the invention
The technical problem to be solved in the present invention is：There is provided a kind of scope of application wider array of aluminium electrolutic capacitor.
The present invention solve its technical problem solution be：A kind of wide-temperature aluminium electrolytic capacitor, includes aluminum hull, is located at
Core bag in aluminum hull, include aluminium lid at the top of the aluminum hull, the upper end of the core bag is provided with binding post, and the core bag includes
There are anode foils, Cathode Foil, the anode foils, Cathode Foil electrically connect with binding post, and the aluminum hull includes shell and inner casing,
The core bag is located in inner casing, and coolant is filled between the shell and inner casing；GBL electrolyte, institute are provided with the core bag
State anode foils, Cathode Foil is immersed in GBL electrolyte, separation layer is provided between the anode foils and Cathode Foil.
As the further improvement of above-mentioned technical proposal, anode foils and the Cathode Foil surface scribbles titanium oxide filming.
As the further improvement of above-mentioned technical proposal, the aluminium lid has plug, and the binding post is arranged on glue
Beyond the Great Wall, the binding post is provided with high temperature resistant foliation.
The beneficial effects of the invention are as follows：The present invention, will not be because of chemistry in work by adding GBL electrolyte in core bag
React and produce water so that high-pressure aluminum electrolytic capacitor is applied to less than -55 DEG C working environments；Simultaneously by the way that aluminum hull is transformed into
The structure of inside and outside shell, and coolant is filled between inside and outside shell so that even if capacitor can also be kept in the case of a high temperature
Normal work, realize a kind of wide aluminium electrolutic capacitor of Applicable temperature scope.
