Aluminum electrolytic capacitor with heat dissipation function

Technical Field

The utility model relates to the technical field of aluminum electrolytic capacitors, in particular to an aluminum electrolytic capacitor with a heat dissipation function.

Background

An aluminum electrolytic capacitor is a common energy storage element, and can be mainly classified into four types, namely a lead type, a horn type, a bolt type and a solid state type. The ox horn type aluminum electrolytic capacitor is also called as a direct-insert type aluminum electrolytic capacitor, has simple structure and convenient installation, and is widely applied to various circuit boards.

When the aluminum electrolytic capacitor is used, the heat generated in the capacitor is usually radiated outwards only by the aluminum shell, but the mode is limited by the air heat conduction rate, the heat radiation effect is poor, and when large current is encountered, the generated large heat is difficult to radiate out in time, so that the capacitance can be damaged.

In view of the above deficiencies of the prior art, the technical problem to be solved in the present patent application is how to provide an aluminum electrolytic capacitor with a heat dissipation function, which has fast heat dissipation, high safety and convenient use.

In order to solve the technical problems, the utility model adopts the following technical scheme:

the utility model provides an aluminum electrolytic capacitor with heat dissipation function, includes capacitor body, anode pin and cathode pin have been drawn forth to capacitor body, still including setting up the shell in the capacitor body outside, insulating end cover and the radiator unit who is used for the lid to close the shell, insulating end cover is worn out to anode pin and cathode pin, its characterized in that, shell and end cover just have the heat-conducting layer to capacitor body fixed mounting, anode pin and cathode pin pass the heat-conducting layer, the equal fixed mounting of the outside of capacitor body and the inside wall of casing has graphite alkene conducting strip, graphite alkene conducting strip is followed the circumference interval of the inside wall of capacitor body and casing is provided with a plurality of, the outside fixed mounting of shell has a plurality of radiating fin, the radiating fin interval sets up.

Like this, the heat that capacitor body produced is to shell internal diffusion, and the graphite alkene conducting strip that sets up through the capacitor body outside accelerates heat diffusion to the casing in, and the heat in the casing passes through graphite alkene conducting strip and transmits for the casing, outwards gives off through the casing, and then radiating fin drives the heat of casing and outwards gives off, improves the radiating effect.

And a plurality of graphene heat dissipation connecting sheets are fixedly arranged between the graphene heat conducting sheets arranged on the outer side of the capacitor body and the inner side wall of the shell. The heat that capacitor body produced passes through graphite alkene heat dissipation connection piece and transmits the heat of the graphite alkene conducting strip in the capacitor body outside for the graphite alkene conducting strip of shells inner wall fast, and then transmits for the casing fast, improves heat dispersion.

The graphene heat dissipation connecting sheet penetrates through the through hole along the vertical direction. The gas in the shell can flow conveniently, the uniformity of heat is improved, and the overhigh local heat is reduced.

Wherein, the radiating fin is annular. Thereby facilitating the improvement of the heat dissipation effect.

Wherein, the heat conduction layer is made of heat conduction silica gel. Is convenient for use.

In conclusion, the aluminum electrolytic capacitor with the heat dissipation function has the advantages of fast heat dissipation, high safety and convenient use.
