Abstract
The utility model relates to a flaming-retardant explosionproof secondary battery pack system with high-efficient cooling function, which is provided with a battery pack encapsulation shell. The encapsulation shell is provided with secondary battery components, the cavity of the encapsulation shell is filled with flaming-retardant explosionproof insulated fluid medium immersing all secondary battery components, the encapsulation shell is provided with an inlet and an outlet of the insulated fluid medium and a heat exchange device is externally connected between the inlet and the outlet to forma closed circulating loop of the insulated fluid medium. The secondary battery pack system has extremely-high cooling efficiency on the battery components and greatly improves the service life of batteries; and meanwhile, the battery pack system is flaming-retardant and explosionproof and has high safe performance.
Description
Technical field
The utility model 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.
The utility model content
The technical problems to be solved in the utility model 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 adopted in the utility model 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 beneficial effects of the utility model are: the battery component of 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 utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
