Description

A kind of ultracapacitor shell

Technical field

The utility model is related to power equipment ultracapacitor field, more particularly to a kind of ultracapacitor shell.

Background technology

Super ultracapacitor (also known as farad capacitor, gold electric capacity) is one kind between traditional capacitance and secondary cell Emerging energy storage electrical equipment.High-specific-power, high current charge-discharge ability, long-life, ultralow temperature performance, the Gao Ke of super capacitor The features such as by property, environmental protection so that it is used as power power-supply in fields such as industrial electronic, communications and transportation, the renewable sources of energy, military affairs Or accumulation power supply is widely used.The reliability of influence ultracapacitor mainly has the following aspects：Internal resistance, machinery knot Structure stability, air-tightness etc..

In structural stability, shell plays vital effect, and current industry is generally aluminium using 1 or 3 is aluminium As the base material of shell, the two respectively has advantage and disadvantage, and 1 is that aluminum profile extrusion performance is good, and internal resistance is low, good heat dissipation, but intensity weak one A bit；3 be that aluminium intensity is good, but deformation is larger in ultracapacitor encapsulation, is unfavorable for the control of size.1 is aluminium shell Intensity difference be mainly reflected in the bottom of shell, some gases can be produced inside it during the ultracapacitor long-term use, Gas build to a certain extent, can produce a larger pressure, if outer casing bottom intensity is poor, can produce some deformation, The cooperation intensity of supercapacitor positive electrode collector and shell is influenceed, so as to influence the stability of internal resistance and the stability of structure.

Utility model content

It is the problem of aluminium outer cover intensity is poor to solve 1, should the utility model proposes a kind of ultracapacitor shell Shell is the tubbiness of one end open, and the bottom centre of the shell is provided with convex reinforcement, for lifting the intensity of bottom, bottom Periphery is provided with recessed annulus, for coordinating with plus plate current-collecting body.

Described ultracapacitor shell is integrally formed, i.e. once cold extrusion pressure is machined, it is not necessary to which extra machine adds Work, it is cost-effective.To improve the success rate of processing, in bottom, the junction of recessed annulus and convex reinforcement uses circular arc Transition is connected, fraction defective during reduction shell extruding.

It is preferred that the shell wall thickness 1mm, bottom gross thickness about 4.5mm, high 140mm.

It is preferred that the convex strengthening tendons quantity is 3-8 bars, preferably 6, structure is reliable, and intensity is high, and processing is simple.

It is preferred that the convex reinforcement width is 2-5mm, preferably 4mm, intensity is good, it is easy to machine-shaping, reduces bad Rate.

It is preferred that the height of the convex reinforcement is 1-3mm, and preferably 2mm, intensity is suitable and saves super capacitor Space inside device.

Beneficial effect：It is the problem of aluminium strength is poor that shelling machine of the present utility model, which substantially improves 1, is passed through The mode of reinforcement increases the mechanical strength of bottom, the deformation of ultracapacitor bottom when internal pressure increases is reduced, so as to ensure The overall structural stability of ultracapacitor；And by the optimization design of the recessed annulus in bottom periphery, cleverly and positive pole Collector coordinates, and saves space, it is ensured that the structure design of other components is unaffected inside ultracapacitor.

Fig. 2 is the ultracapacitor cut-away view of outer cover of the utility model embodiment 1.

Fig. 3 is the ultracapacitor outer casing bottom detailed cross sectional view of the utility model embodiment 1.

The sectional view that Fig. 4 coordinates for the ultracapacitor shell and plus plate current-collecting body of the utility model embodiment 1.

Embodiment

The utility model is further illustrated with example below in conjunction with the accompanying drawings.

Embodiment 1

As shown in figure 1, the convex reinforcement 101 of outer casing bottom, quantity is 6, width is 4mm, is highly 2mm, Bottom centre position of the cloth in ultracapacitor shell

As shown in Fig. 2 the recessed annulus 102 of outer casing bottom, the recessed annulus in bottom and convex reinforcement junction 103, the depth of recessed annulus 102 is 2mm, and width is 4.5mm, for coordinating with plus plate current-collecting body, saves ultracapacitor Internal space.Junction 103 is connected using a diameter of 3mm arc transition, it is ensured that the mobility of aluminium during extruding, reduction life Fraction defective during production, it is cost-effective.

As shown in figure 3, outer casing bottom is longitudinally provided with reinforcement 105, outer casing bottom is improved jointly with convex reinforcement 101 Mechanical strength, be difficult deformation, meet the stability that uses of the ultracapacitor under harsh and unforgiving environments.

As shown in figure 4, the plus plate current-collecting body 106 of ultracapacitor, the lower convex portion 107 of the periphery of plus plate current-collecting body 106, under Lug boss 107 is just stuck in the recessed annulus 102 in bottom of shell, and the two cooperation is ingenious, saves the sky inside ultracapacitor Between, mechanical structure is stable, reliable.
