Description
[technical field]
This utility model relates to technical field of electronic components, specifically a kind of novel all-in-one ultracapacitor anti-explosion valve structure.
[background technology]
Ultracapacitor is a kind of novel energy-storing device with high-specific-power, long-life, of a relatively high energy density.Important application is had in fields such as electronic product, new-energy automobile, new forms of energy (solar energy, wind energy etc.)/intelligent grid energy storage.Cylindrical supercapacitor has higher energy density and lower internal resistance, has the advantage of uniqueness in traffic application.
At present, the duricrust encapsulating structure of most of ultracapacitors, in order to avoid in use temperature is too high, causes air pressure inside excessive and causes monomer to explode, all on the position that monomer surface is suitable, as processed the position with certain weak degree on housing or on polar cap.When capacitor arrangement air pressure inside reaches to a certain degree, weak part ftractures and rushes down pressure, thus avoids bringing bigger danger.But, in practical operation, it is difficult to ensure that the precision of shell weak part processing, it is difficult to ensure that capacitor bursts under suitable temperature/pressure, thus do not have purpose that is explosion-proof and that reduce harm., at present explosion-proof valve and liquid-entering hole are incorporated on a polar cap meanwhile, share a liquid injection hole and remain rare, it is possible to accurately controlling anti-explosion valve structure, the explosion-proof pressure and the explosion-proof concordance that reach different stage are the most difficult.
[utility model content]
This utility model is the structure for most of cylindrical supercapacitors, avoid in use internal temperature too high, cause air pressure inside too big and there is the danger of blast, the problem causing certain hidden danger to the safety of product, it is provided that a kind of easy to process, easy to use, explosion-proof pressure is adjustable controlled novel all-in-one ultracapacitor anti-explosion valve structure.
To achieve these goals, a kind of novel all-in-one ultracapacitor anti-explosion valve structure of design, including polar cap, liquid injection hole, explosion-proof valve, rupture pressure disc and sealing ring, polar cap is processed a circular hole, liquid injection hole and explosion-proof valve share described circular hole, circular hole can do fluid injection and pressure release multiple action, and the valve gap of described explosion-proof valve is provided with rupture pressure disc.
Explosion-proof valve and circular hole junction are provided with sealing ring.
The valve gap outermost end of explosion-proof valve is provided with a barb structure.
Integration ultracapacitor anti-explosion valve structure can apply to cylindrical or square duricrust.
Integration ultracapacitor anti-explosion valve structure, by adjusting the thickness 10-50 μm of rupture pressure disc, adjusts the explosion-proof pressure of 5-20kg.
This utility model compared with the existing technology, has an advantage in that:
1. liquid injection hole and explosion-proof valve share circular hole, and circular hole can do fluid injection and pressure release multiple action, and the structure of this integration simplifies the design of polar cap, saves manufacturing cost；
2. rupture pressure disc thickness is controlled, when the temperature within ultracapacitor raises, and when air pressure increases to a certain degree, air pressure overcomes the rupture pressure disc of valve gap outer end, plays the effect of pressure release, cooling, and this design makes explosion proof ratings controlled, and concordance is good；
3. it is suitable for power lithium-ion battery, is not only applicable to cylindrical supercapacitor, be simultaneously suitable for square monocoque of Denging；
4. there is a barb structure in valve gap outermost end, prevent external force during transport, use from rupture pressure disc causing damage, rupture pressure disc harm when going out to external world can be slowed down simultaneously.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model；
In figure: 1. polar cap 2. liquid injection hole 3. explosion-proof valve 4. rupture pressure disc 5. sealing ring.
[detailed description of the invention]
The utility model is described in further detail below in conjunction with the accompanying drawings, and this structure and principle are the most clearly for the people of this specialty.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
The purpose of this utility model is primarily directed to the structure of most of cylindrical supercapacitor, in order to avoid in use internal temperature is too high, cause air pressure inside too big and there is the danger of blast, the most most selection is to process weak part on column structure, so that it can capacitor internal energy be not too time pressure release, reduce harm and loss.But, in real process, it is difficult to accomplish accurate pressure release, monomer or in advance explosion or can not play explosion-proof purpose, cause certain hidden danger to the safety of product.This utility model simplifies the structure of cylinder blanket, the thickness of explosion-proof valve can accurately control (10-50 μm), and then can accurately control explosion-proof pressure, and on polar cap, process appropriately sized circular hole, this circular hole can do fluid injection and pressure release multiple action.Explosion-proof valve both can do the valve gap sealed, and is provided that again accurate explosion-proof, and feature is to be integrated with a protruding weak circular rupture pressure disc on valve gap.According to PV=nRT equation, according to different designs and applying working condition, the pressure that can bear inside whole monomer can be calculated, can accurately process the rupture pressure disc of different-thickness.So can play different explosion-prooves, reach different explosion proof ratings, there is good explosion-proof concordance, simultaneously, a barb structure is had in valve gap outermost end, it is possible to prevent external force during transport, use that rupture pressure disc causes damage, rupture pressure disc harm when going out to external world can be slowed down simultaneously.
See polar cap in Fig. 1, this explosion-proof valve, liquid injection hole, explosion-proof valve concentrate on a polar cap, and liquid injection hole and explosion-proof valve share a hole, and this is that a kind of structure is simplified, simple structure design.When injecting electrolyte, liquid injection hole plays fluid injection effect, was sealed by liquid injection hole with explosion-proof valve and sealing ring later, prevents electrolyte from spilling the infiltration with water.In use, owing to monomer temperature raises, monomer air pressure inside can be caused to promote, the explosion-proof valve film on explosion-proof valve can be broken through by the most too high pressure, monomer internal pressure is released in time, plays the purpose of pressure release and cooling.This rupture pressure disc thickness according to different battery core design and use operating modes, can produce the rupture pressure disc (10-50 μm) of different-thickness, can accurately accomplish the explosion-proof pressure of 5-20kg.
