Point, obtain applications well in batteries of electric automobile bag at present.But the performance of lithium-ion-power cell is more sensitive to temperature change,
Large Copacity, the high power lithium ion cell particularly used on vehicle.Loading space on vehicle is limited, cell number needed for vehicle
Mesh is larger, and battery is close-packed arrays connection.When vehicle is in the different traveling shapes of the checkers such as high speed, low speed, acceleration, deceleration
When being run under condition, battery can be discharged with different multiplying, amount of heat be produced with different heat speed, plus accumulated time and sky
Between influence that the aggregation of uneven heat can be produced, so as to cause battery pack operating ambient temperature complicated and changeable.Due to the cell body that generates heat
It is intensive put, intermediate region certainty heat aggregation it is more, fringe region is less, adds the temperature between constituent parts in battery bag
Spend unbalanced, aggravate each battery module, monomer internal resistance and capacity inconsistency.If long time integration, percentage of batteries can be caused
Overcharge and overdischarge, and then life-span and the performance of battery are influenceed, and cause potential safety hazard.If batteries of electric automobile group is in height
It cannot get timely ventilation and heat under temperature, it will cause that battery pack system temperature is too high or temperature distributing disproportionation is even, most reduce at last
Battery charging and discharging cycle efficieny, the power and energy for influenceing battery play, thermal runaway will be also caused when serious, influences the peace of battery
Full property and reliability.Therefore in order that battery bag plays optimum performance and life-span, it is necessary to optimize the structure of battery bag, it is carried out
Heat management, increase cooling facilities, control the temperature environment of battery operation.
Mainly there are two kinds of approach to solve lithium ion battery heat dissipation problem at present：One kind is by forced air cooling mode, separately
Outer one kind is to pass through water-cooling pattern.Forced air cooling mode radiating efficiency is relatively low.Traditional cooling by water pipeline, lithium-ion electric core and water
Cold pipe contact area is smaller, influences the radiating efficiency of battery core.
Utility model content
Goal of the invention of the present utility model is：For above-mentioned problem, there is provided one kind on the outside of battery core by setting
Cooling jacket is put to increase lithium ion battery and coolant contact area and then effectively improve the lithium ion battery of radiating efficiency
Water-cooling structure.
The technical solution adopted in the utility model is as follows：
A kind of water-cooling structure of lithium ion battery, specifically includes battery core, water jacket, coolant and shell, and the water jacket is song
Linear structure and it is coated in closed on the outside of battery core, the battery core coated by water jacket is dipped in the coolant, the coolant
It is arranged in the shell, the shell is provided with water inlet and delivery port.
Further, the single water jacket is coated on the outside of the single battery core in closed.
Further, the water-jacket outer wall is provided with coolant flow direction control structure.
Further, the coolant flow direction control structure correspondingly connects the water-jacket outer wall and the shell.
Further, the coolant flow direction control structure is arranged on the water-cooling structure bottom.
Further, the coolant flow direction control structure is arranged on rear side of the delivery port.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：Curve shape water jacket bag
Overlay on the outside of battery core, increase effectively the contact area of lithium ion battery and coolant；Battery core carries out heat transfer with water jacket inwall,
Water-jacket outer wall carries out effective radiating of the convection current realization to battery core with coolant, effectively increases the radiating efficiency of lithium ion battery.
