The utility model preferred embodiment provides a kind of battery cooling apparatus, applied to the battery for including multiple cells
Module.
As shown in figure 1, the battery cooling apparatus includes platy structure 100, the platy structure 100 offers multiple use
In the through hole 130 for accommodating battery.The platy structure 100 includes first surface 110 and second surface 120, the first surface
110 and second surface 120 be oppositely arranged, each through hole 130 on the platy structure 100 is through the He of first surface 110
Second surface 120.
Wherein, a cell can be accommodated in each through hole 130.During implementation, each monomer electricity in battery modules 200
In pond insertion respective through hole 130.
Alternatively, the size and shape of the through hole 130 can mutually agree with the size and shape of corresponding cell,
That is, in actual applications, the size and shape of through hole 130 can carry out relative set according to the different of application.
In the present embodiment, the platy structure 100 is made up of Embedding Material, such as：Silica gel, rubber, epoxy resin, poly- ammonia
Ester etc..The present embodiment is not limited to the particular type of Embedding Material.The entirety of battery modules can be strengthened using Embedding Material
Property, improve the resistance to external shock, vibrations, it is possible to increase the insulation between inner member, circuit.
In the present embodiment, phase-change material is added with the platy structure 100, its specific addition manner has a variety of.
Such as：Directly the phase-change material that outer wrap has polymeric membrane can be added in flowable Embedding Material and mixed
Close, then be blended with the Embedding Material of phase-change material and pour and build up the platy structure 100.
In this way, the phase-change material is located inside the platy structure 100, and wrapped by polymeric membrane, in phase transformation
During will not leak.It should be noted that platy structure 100 provided by the utility model is sealing structure.
Phase-change material refers to vary with temperature and change state of matter and can provide the material of latent heat.Change physical property
Process is referred to as phase transition process, and phase-change material will absorb substantial amounts of latent heat during this.The above-mentioned phase transformation material for being enclosed with polymeric membrane
Material can be phase-change microcapsule.
Phase-change microcapsule, exactly coat one layer of stable performance in solid-liquid phase change material microparticle surfaces using microcapsules technology
Film and the composite phase-change material with core shell structure formed.The phase-change material can be crystalline hydrate salt, eutectic hydrated salt,
Paraffin class, fatty acid, polyethylene glycol etc., the present embodiment is without limitation.
When battery modules produce amount of heat, the heat that phase-change material can absorb each cell is undergone phase transition.Due to
Phase-change material outer wrap has polymeric membrane, and in the platy structure 100 of sealing, the phase transformation material described in phase transition process
Material will not leak.
In another example shown in Fig. 2, liquid stream runner 140, the liquid stream runner can be offered inside the platy structure 100
140 are located on the multiple through hole 130.That is, the phase-change material in liquid stream runner 140 can pass through the liquid stream runner 140
Side wall and the multiple through hole 130 in cell mediate contact.In the present embodiment, the phase-change material can make an addition to
In the liquid stream runner 140.
According to the actual requirements, the side of the platy structure 100 offers the opening connected with the liquid stream runner 140
150.During implementation, 150 phase-change material can be filled into by the opening in the liquid stream runner 140, then by the opening
150 seal up.
In this way, cell in through hole 130 can with the phase-change material mediate contact in liquid stream runner 140,

Gap between the madial wall of aperture where lateral wall and the battery model be present, between the gap is less than between each battery model
Away from.
Flowable Embedding Material is filled in gap in the uncovered box, coagulates the flowable Embedding Material
Gu into the sealing structure for the lateral surface for wrapping each battery model.
After the flowable Embedding Material is frozen into the sealing structure, all electricity in the uncovered box are taken out
Pool model, and open up in the side of the sealing structure two openings 150, each opening 150 is to prolonging inside the sealing structure
Extend the stereochemical structure.
The stereochemical structure is dissolved, the liquid stream connected with described two openings 150 is internally formed in the sealing structure
Runner 140.In this way, the sealing structure with liquid stream runner 140 finally given is the platy structure 100.
In this way, on the madial wall and the platy structure 100 of the platy structure 100 between the lateral wall of each through hole 130
Gap be present, the gap is connected into the liquid stream runner 140.That is, the side wall of each through hole 130 is also the liquid stream stream
The side wall in road 140.
According to the actual requirements, the arrangement of each cell has differences in different battery modules 200, for different rows
Cloth, when preparing battery cooling apparatus, different stereochemical structures can be used as mould.In this way, the platy structure 100 prepared
The structure of included liquid stream runner 140 can also change according to the difference that cell is arranged.
In actual applications, the spacing between each cell may be incomplete same.In the less monomer of multiple spacing
Liquid stream runner 140 is opened up between battery, technology difficulty is larger, can also improve manufacturing cost.Therefore, it is possible to by liquid stream runner 140
Set along the lateral wall of the less cell of the multiple spacing is rich.
As shown in Figure 3, it is assumed that the platy structure 100 includes region I, region II and region III, and wherein region I includes two
Individual through hole 130, region II include five through holes 130, and region III includes three through holes 130.Liquid stream in the platy structure 100
Runner 140 can be by the gap between the lateral wall of the region I, region II and region III and the lateral wall of platy structure 100
Connection forms.
Alternatively, in the present embodiment, the thickness of the platy structure 100 can be more than or equal to the cell.Such as
This, the area that can increase platy structure 100 and cell maximizes, and further improves radiating effect.
