Bag.On the one hand battery bag is constantly in suitable use environment, the amount of heat of battery bag running generation is taken away in time.
On the other hand make in battery bag that keeping temperature is homogeneous between each battery cell, avoid due to battery pressure difference caused by excessive temperature differentials,
Can not only be effectively improved the chemical property and service life of battery, and thermal runaway is hidden caused by can avoiding hot-spot
Suffer from.
The technical scheme of the application is：A kind of cold safety battery bag of complete immersion formula liquid, including：
The battery case being made up of casing and case lid, and the battery pack in the battery case is contained in, the battery pack includes
The battery cell that some connection in series-parallel are combined；
Liquid cold-heat-exchanging exchange system on its inside is provided with the case lid, is provided with described in each in the casing
Battery cell submerges liquid in the inner, and the liquid is that boiling point is the heat absorption phase transformation material in the range of 5-45 DEG C
Material.
The liquid is selected from least one in HFC, hydrofluoroether, perfluocarbon.
Gap between each described cylindrical battery monomer is not more than 5mm.
The liquid cold-heat-exchanging exchange system includes the coolant runner pipe and the coldplate that are fixed on the case lid, the cooling
The liquid in-out mouthful of liquid runner pipe is stretched out outside the battery case.
The coldplate is arranged in the top of the coolant runner pipe.Or, the coolant runner pipe is arranged in institute
State inside coldplate.
The battery cell is the lithium battery monomer of cylinder.
Unidirectional relief valve is installed on the casing or case lid.
The casing and case lid outside are provided with adiabator layer.
The advantage of the application is：
1st, space is saved, it is to avoid the system equipment space requirement needed for air cooling, water-cooled.
2nd, be totally submerged for every battery cell by the liquid of phase-change material, improves the temperature uniformity of battery pack,
Effect is significantly better than air cooling or water-cooled.
3rd, be totally submerged for each battery cell by phase change material, it is to avoid the water vapour to be formed due to colding and heat succeed each other is attached to electricity
Chi Shang, triggers the potential safety hazards such as short circuit.
Brief description of the drawings
In order to illustrate more clearly of the technical scheme of the embodiment of the present application, below will be to be used needed for embodiment description
Accompanying drawing be briefly described, drawings in the following description are only some embodiments of the present application, for the common skill in this area
For art personnel, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the cold safety battery bag of complete immersion formula liquid in the embodiment of the present application；
Wherein：1- casings, 2- case lids, 3- battery cells, 4- liquids, 5- coldplates, 6- coolant runner pipes.
Specific embodiment
Such scheme is described further below in conjunction with specific embodiment.It should be understood that these embodiments are for illustrating
The application and be not limited to limit scope of the present application.The implementation condition used in embodiment can be done according to the condition of specific producer
Further adjustment, unreceipted implementation condition is usually the condition in normal experiment.
Fig. 1 shows a specific embodiment of the application cold safety battery bag of this complete immersion formula liquid, with conventional batteries
Bag identical is, it includes battery case and the battery pack being housed in the battery case, wherein battery case by open topped casing 1
And be encapsulated in the case lid 2 of the casing open-mouth and constitute, the battery case fully meets IP67 seal requests.Battery pack is high-capacity lithium
Battery pack, it includes that (under normal circumstances, these battery cells rely on battery for battery cell 3 that numerous connection in series-parallel combine
Fixture and the combination of connection in series-parallel current carrying lug link together).Can there is certain gap between each battery cell 3, but between this
Gap is generally no greater than 5mm.
In the present embodiment, battery cell 3 is the lithium battery monomer of cylinder.Certainly, the technical scheme of the application is equally fitted
For the battery pack of other structures form, such as diamond type battery.
The key improvements of the present embodiment are that liquid cold-heat-exchanging exchange system on its inside, casing 1 are provided with case lid 2
Inside it is provided with and all of battery cell 3 is submerged into liquid 4 (under normality, it is liquid) in the inner, and the liquid
Material 4 is that boiling point is the heat absorption phase-change material in the range of 5-45 DEG C.
Above-mentioned boiling point is the commodity that the liquid 4 in the range of 5-45 DEG C can be outsourcing, selectable to have HFC, hydrogen
Fluorine ether, perfluocarbon etc., it is of course possible to using HFC, hydrofluoroether, the mixture of the combination of two of perfluocarbon or three
The mixture for all combining.
Above-mentioned liquid cold-heat-exchanging exchange system can use various structure types well-known to those skilled in the art, specifically at this
In embodiment, the device includes the coolant runner pipe 6 and coldplate 5 that are fixed on the case lid 2, and coolant runner pipe
6 liquid in-out mouthful is stretched out outside battery case, and coolant is passed through to the coolant runner pipe 6 to facilitate.
Coldplate 5 and generally contacted with each other arrangement in coolant runner pipe 6, so that the low temperature of coolant runner pipe 6 can
Faster it is transferred to coldplate 5.Also, coldplate 5 to be arranged in the present embodiment the top of coolant runner pipe 6, to allow
The ebullition, gasification of liquid 4 is stated to be fully contacted and heat release with the coldplate 5 and coolant runner pipe 6.
Certainly, can also be arranged in coolant runner pipe 6 inside coldplate 5 by we, so as to allow the two to be fully contacted, make
The low temperature of coolant runner pipe 6 further can quickly pass to coldplate 5.
During practical application, when the battery pack system carries out charge or discharge, battery can produce substantial amounts of heat, above-mentioned
Liquid 4 is heated can occur ebullition, gasification, and liquid gasification absorbs the heat that each battery cell 3 is produced, and reaches reduction battery
The purpose of temperature.To avoid battery case internal pressure builds, cooling water or other coolants are passed through in coolant runner pipe
Body.Steam in casing after gasification rises, and liquefaction (vapour is contacted with coldplate and coolant runner pipe) occurs to the cold, again
Drippage goes back, and is moved in circles with this and used.Be totally submerged for battery by liquid 4, is distributed in each periphery of batteries monomer 3,
Ensure that each batteries monomer is completely attached to the liquid 4, so that battery bag is transported under relatively stable thermal environment
OK.
It can be appreciated that be arranged on above-mentioned liquid cold-heat-exchanging exchange system on case lid 2 rather than on casing by the present embodiment, can be generous greatly
Just the assembling and maintenance of the battery bag.
Casing 1 and the outside of case lid 2 can increase adiabator layer, generally need to install unidirectional pressure release on casing 1 or case lid 2
Valve.
Above-described embodiment is only the technology design and feature for illustrating the application, its object is to allow people to will appreciate that this Shen
Content please is simultaneously implemented according to this, and the protection domain of the application can not be limited with this.It is all according to the application main technical schemes
Equivalent transformation or modification that Spirit Essence is done, should all cover within the protection domain of the application.
