Background technique
With the continuous development of new-energy automobile, lithium battery has been widely used for battery car and plug-in mixing is dynamic
Power automobile.And the battery life of lithium battery, course continuation mileage etc. are the bottleneck problems of Gonna breakthrough needed for wideling popularize new-energy automobile,
It in the prior art, is to guarantee normal battery operation and service life, battery is cooling gradually have been had and air-cooled be changed into water cooling.And cold plate
The indispensable critical piece of battery water cooling system, the structure type of cold plate also due to the arrangement of vehicle not
Together, but its working principle is all that the heat distributed when battery works passes to inside cold plate and with the contact of the surface of cold plate
Coolant liquid, coolant liquid are distributed by low-temperature radiator or battery cold, and circulation in cycles is to guarantee battery just
Normal working environment and service life.
Existing cabinet water-cooled plate and cabinet for electric automobile power battery is one of the forming, prior art battery case
Water-cooled plate and cabinet in body are fixed composition, can not be decoupled.This structure has 2.1, product is whole more stupid
Again, inconvenient when installation.2 be that in winter, when under cold situation, battery does not need to cool down under normal circumstances, and there is no need to water coolings
Device.
Summary of the invention
Technical problem to be solved in the utility model is to overcome drawbacks described above of the existing technology, provides a kind of use
In the water-cooled plate of new energy car battery cabinet.It can be decoupled with the cabinet of electric automobile power battery is arranged, easy for installation.
Winter is removable to be unloaded down.
It is as follows that the utility model solves technical solution used by its technical problem: one kind being used for new energy car battery case
The water-cooled plate of body, including flat aluminium alloy plate, water-cooled layer and sealing plate, flat aluminium alloy plate are bonded with battery surface, are set inside water-cooled layer
There is circulating cooling water channel, circulating cooling water channel is end to end, and outside is equipped with inlet and outlet, and both ends are sealed by sealing plate；
It is integral that shape is welded in such a way that agitating friction welds between water-cooled layer and flat aluminium alloy plate and sealing plate.The both ends of water-cooled plate are set
It is equipped with the connection structure that can be detachably connected with power battery cabinet.
Further, flat aluminium alloy plate is formed by hot extrusion technique；Cyclic water channel is single arcuate cyclic water channel.
Further, the connection structure is several bolts hole protruded from water-cooled plate ontology.
Further, sealing plate is formed as the structure of bar shaped, described with a main body and the lug boss being integrally formed with main body
Flat aluminium alloy plate, water-cooled layer end be formed with the concave portion for accommodating lug boss.
The utility model has the beneficial effects that the both ends of (1) water-cooled plate, which are provided with, to be detachably connected with power battery cabinet
Connection structure.The utility model overcomes drawbacks described above of the existing technology, provides a kind of for new-energy automobile electricity
The water-cooled plate of pond cabinet can decouple with the cabinet of electric automobile power battery and be arranged, easy for installation.Under winter is detachable
Come；(2) connection structure is several bolts hole protruded from water-cooled plate ontology, is disassembled and installed so all very convenient；(3)
Be formed as the structure of bar shaped by sealing plate, with a main body and the lug boss being integrally formed with main body, flat aluminium alloy plate, water
The end of cooling layer is formed with the concave portion for accommodating lug boss, ensure that sealing performance and intensity, impact resistance and vibrating effect
Well.
