It is with new-energy automobile constantly universal, in order to excavate the overall performance of battery system to a greater degree, improve the longevity
Life, increasingly payes attention to the heat management of battery pack, and the temperature equalization and temperature control in battery between battery are more and more finer.
Heat managements all at present mostly uses greatly air-cooled and liquid cooling scheme, air-cooled because being difficult to solve temperature uniformity and area
The problems such as popularization, therefore more use liquid cooling scheme.Liquid cooling in battery modules mainly by arranging liquid cooling plate, in liquid cooling plate
Runner is set, and coolant liquid recycles in runner, so that the heat of generation be taken away.But the shortcomings that above scheme, is: 1, electric
Electrical automobile may will appear coolant liquid and leak out danger in extreme driving process because vibrating or colliding；2, liquid cooling plate structure is more multiple
Miscellaneous, processing technology and installation difficulty increase, while mould group takes up space and weight increases, and cost improves；3, complicated runner meeting
Resistance is significantly increased, it is larger to easily cause the module internal head and the tail temperature difference, has a huge impact to battery capacity and service life.
Utility model content
Purpose of the utility model is to solve above-mentioned existing defect, provide a kind of structure is simple, be easily installed,
The battery liquid cooling mould group with confluence effect that battery core radiates and even temperature effect is good.
To achieve the above object, the technical solution of the utility model is as follows:
A kind of battery liquid cooling mould group with confluence effect, which is characterized in that including upper battery core anode liquid cooling mould group, lower electricity
Core cathode liquid cooling mould group and the battery core being installed between battery core anode liquid cooling mould group and lower battery core cathode liquid cooling mould group, it is described
Upper battery core anode liquid cooling mould group and lower battery core cathode liquid cooling mould group are welded by liquid cooling plate and cupro-nickel composite sheet, in the liquid
Be provided with several battery core fixing grooves on cold plate, the battery core positive or negative pole pass through after battery core fixing groove with cupro-nickel composite sheet spot welding
Connection, the liquid cooling plate includes middle boss and the side boss for being respectively provided at middle boss two sides, and the side of the middle boss is provided with
Cooling liquid inlet, the side for setting up the side boss of the middle boss two sides separately are equipped with cooling liquid outlet, lead on the liquid cooling plate
A coolant liquid cooling circuit can be formed by crossing boss and side boss in setting, and the cooling liquid inlet of boss side enters in coolant liquid warp
The middle boss other side is flow to behind liquid cooling plate inside, so while bidirectional shunt is back to after in boss boss side coolant liquid
The bottom of outlet outflow, the heat that coolant liquid generates in flow process to absorb battery core, the liquid cooling plate is multiple by cupro-nickel
Close piece sealing.
The coolant liquid is deionized water or silicone oil or fluorination liquid as a preferred technical solution,.
The utility model has the following beneficial effects: without the separately installed flow channel for liquids in liquid cooling plate, structure is simple, institute's duty
Between it is small, be easily installed, meanwhile, reduce the installation difficulty of manufacturing process and mould group, battery pack using light-weight design, cost compared with
It is low.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the battery liquid cooling mould group with confluence effect of the utility model；
Fig. 2 is the main view of liquid cooling plate in Fig. 1；
Fig. 3 is the top view of liquid cooling plate in Fig. 1.
In figure: battery core cathode liquid cooling mould group under the upper battery core anode liquid cooling mould group of 1-, 2-, 3- battery core, 4- liquid cooling plate, in 4-1-
