Description
Technical field
The present invention relates to a kind of fire and explosion proof type secondary batteries system with highly efficient cooling function.
Background technology
The application of secondary cell more and more widely.Use the local secondary cell of more high-power electric energy generally to use at needs with the form of battery pack.Battery pack produces bigger heat in the use meeting, influences stability, fail safe and the useful life of element cell itself, so it needs corresponding heat abstractor heat sinking function is provided.The heat abstractor of present secondary cell, except air-cooled be to be coolant with the air, other for this special object of battery, coolant does not directly contact with battery component, but adopt the mode of indirect contact to carry out heat exchange, cause cooling effectiveness lower.The heat abstractor cooling effectiveness of therefore present secondary cell all is not very high, can not guarantee battery stability, fail safe and useful life in use.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome prior art for the not good defective of the existing radiating effect of heat dissipation problem that solves in the use of secondary cell battery group, in order further to improve fail safe, reliability and the useful life that secondary cell battery group is used, provide a kind of fire and explosion proof type secondary batteries system simultaneously with highly efficient cooling function.
The technical solution used in the present invention is: a kind of fire and explosion proof type secondary batteries system with highly efficient cooling function, has the pack shell, be furnished with secondary battery module in the package casing, fill the fire-retardant antiknock type dielectric fluid medium of full all secondary battery modules of submergence at the package casing inner chamber, package casing is provided with the import and export of dielectric fluid medium, and external heat-exchange device forms the closed loop of dielectric fluid medium between the import and export.
Described dielectric fluid medium employing transformer oil or cold oil or lubricating oil or other have the material of dielectric fluid characteristic.
External heat-exchange device adopts fin or radiating tube or other to have the assembly of heat sinking function between import and export.
The invention has the beneficial effects as follows: the battery component of this secondary batteries system is encapsulated in the closure, avoid outside destroy, battery component is immersed in the fire-retardant antiknock type dielectric fluid medium fully, cooling is more thorough, even under the cycling hot exchange interaction of medium, cooling effectiveness is high, so battery improves useful life greatly; Simultaneously, fire-retardant antiknock type dielectric fluid medium has fundamentally suppressed to cause the undesirable element that unexpected situation appears in battery component, and battery is played practical protective effect, and flame-proof explosion-proof has improved the fail safe that battery pack system uses greatly.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of secondary cell battery group of the present invention.
1. package casings, 2. battery components, 3. fire-retardant antiknock type dielectric fluid media among the figure
Embodiment
As shown in Figure 1, a kind of fire and explosion proof type secondary batteries system with highly efficient cooling function, has pack shell 1, be furnished with secondary battery module 2 in the package casing 1, fill the fire-retardant antiknock type dielectric fluid medium 3 of full all secondary battery modules 2 of submergence at package casing 1 inner chamber, have the material of dielectric fluid characteristic as transformer oil, cold oil, lubricating oil or other; Package casing 1 is provided with the import and export of dielectric fluid medium 3, and external heat-exchange device forms the closed loop of dielectric fluid medium 3 between the import and export; Heat-exchange device can adopt fin or radiating tube or other to have the assembly of heat sinking function.
In the present invention, secondary battery module, fixed insulation parts etc. all adopt corrosion-resistant, high-low temperature resistant in pack shell, the shell, and the higher material of anti-external force performance is made simultaneously.Secondary battery module is made up of single or multiple element cell matching battery snap gauges, bonding pad, power supply wiring etc., and each parts all adopts corrosion-resistant, high-low temperature resistant, and the higher material of anti-external force performance is made simultaneously.The fixed insulation parts can adopt synthesizing polymeric material to make, as phenolic resins, polyurethanes, mylar, polyamide, propylene, urea aldehyde melmac, silicones etc.For the dielectric fluid medium, then adopt have the superior isolation performance, nontoxic, anti-combustion antiknock, to metal and nonmetal no corrosiveness have the critical temperature height simultaneously, the material of characteristics such as setting temperature is low, heat exchange performance is high, easily discover when revealing serves as.
In the present invention, secondary battery module is immersed in the dielectric fluid medium fully, the contact area of battery component and dielectric fluid medium increases greatly on the one hand, heat exchanger effectiveness improves, the dielectric fluid medium can circulate between the battery unit assembly equably on the other hand, makes cooling more even, avoids between the part heat unbalanced, thereby guarantee that effectively battery temperature is controlled in the range of safety operation, has improved the useful life of secondary battery module.Simultaneously, fire-retardant antiknock type dielectric fluid medium can effectively prevent the generation of unexpected situations such as battery burning or blast, and battery is played practical protective effect, has further improved fail safe, reliability that battery uses.
In sum, its cooling capacity for battery component of secondary batteries system of the present invention, cooling Effect compared with prior art greatly improves, and battery pack prolongs service life, simultaneously also fundamentally Suppressed to cause the undesirable element that unexpected situation appears in battery component, whole battery pack is had conscientiously to be had The protective effect of effect, burn-proof and explosion prevention, the security that battery uses is very high.
The present invention is specially adapted to high-power power battery, and especially the combination of lithium-ion-power cell should With, application surface relates to the row such as electric automobile, electric bicycle, electric tool, portable power source, energy storage Industry also relates to the fields such as military affairs, space flight.
