Description
Technical field
The invention belongs to lithium battery thermal management technology fields, are related to a kind of liquid-cooling heat radiation piece.
Background technique
The present invention relates to lithium battery thermal management technology, lithium battery includes hard quadrate lithium battery, soft package lithium battery, cylindrical lithium
Battery；Liquid-cooling heat radiation piece also refers to that liquid-cooling heat radiation, medium include the liquid substance including the grease of water, freezing liquid, good fluidity, is
With it is air-cooled corresponding, belong to active high efficiency and heat radiation technology；Heat dissipation refers to cooling and heating, can carry out temperature control to battery
System makes it possible to work in suitable temperature.
Lithium battery heat management is divided at present: natural cooling, wind-cooling heat dissipating and water-cooling；Natural cooling is without any radiating part
Part, by self-radiating；Wind-cooling heat dissipating relies on cooling fin and fan, takes away internal heat of battery, this mode is by environment temperature shadow
It rings, it is limited actually to cool and heat effect, but cheap, implements simple；Active water cooling method, passes through pipeline
To inside battery, liquid can be to be heated or cooled liquid, by liquid forced flow, heat is brought or taken out of into battery, electricity
Heating or cooling inside pond, make battery work in optimum state, extend battery life, improve battery efficiency, this is only secondary at present
In direct-cooled most efficient heat management mode.
Since active liquid-cooling heat radiation technology is complicated, technology is there are also many defects at present, and there are two types of mainstream technologys: one is straight
Connecing will have the aluminium flake of capillary pipeline to be placed between battery, and there is an oval vacancy in capillary pipeline outlet, aluminium flake and frame
The advantages of vacancy, which is stacked together, constitutes sprue, this technology is that liquid cooling piece is placed between battery, the disadvantage is that stacking shape
At sprue it is very fragile, length of sealing line is long, in the automobile use environment jolted, be easy to cause liquid leakage, needs
High dimension process stability.
Another is bottom or side one liquid cooling plate of setting in battery pack, places the cooling fin without runner between battery
It is connect with liquid cooling plate, the heat of battery is by no runner fin conductive to liquid cooling plate.The method avoids the first technologies
Defect improves sprue and liquid cooling plate leakproofness, the disadvantage is that heat is not conducted to liquid cooling plate directly, but is dissipated by no runner
Backing is indirectly transferred to liquid cooling plate, while liquid cooling plate determines that contact area is less than former technique in bottom and side, leads to heat
Conduction efficiency is low.
By taking energy density 230Wh/kg lithium battery pack as an example, at 25 DEG C of room temperature, cycle life >=2000 time, 45 DEG C of high temperature
Under, cycle life can only >=1200 times, service life of lithium battery is influenced to be significant by battery temperature；Low temperature charging simultaneously, when charging
Between long, than the 25 DEG C charging time of -25 DEG C of charging time slow 63%.Therefore effectively control battery temperature is to improve battery life, is added
The key factor of charging quickly.
In use due to lithium battery, since internal gas gathers, the rectangular aluminum hull of hard or soft package be will lead to
Bulging phenomenon occurs, overstocks the cooling fin fluid passage wherein placed, physical channel area is caused to reduce, or even blocks completely,
Cause to radiate bad.
It is de- that separation cannot be occurred because cooling fin needs to form wave feature around round for cylindrical battery core
Glue；As the core component of heat management system, liquid cooling piece plays an important role wherein, it is desirable that small in size, at low cost, reliability
Height, flexibility ratio is big, and heat transfer efficiency is high, and is able to bear pressure caused by battery core bulging, keeps channel unimpeded, and adapt to justify
