Description
Technical field
It the utility model is related to battery thermal management technical field, and in particular to a kind of to cool down based on air and phase-change material
Battery module.
Background technology
Lithium battery is the power resources of pure electric automobile, and its temperature characterisitic directly affects the performance, safe and reliable of electric car
Property, service life etc., and the uniformity in temperature field has a great influence to capacity and discharging efficiency.Security is further improved, is protected
It is most important in security interval, the research for battery thermal management to demonstrate,prove battery operation.
At present, battery thermal management is broadly divided into three kinds according to heat transfer medium：Air-cooled, liquid is cold and phase-change material cools down.It is air-cooled
The coefficient of heat transfer is low, and cooling, firing rate are slow.Liquid-cooling heat radiation is preferable, but pipeline arrangement is complicated, and weight is relatively large.And phase transformation material
Material has higher latent heat and thermal conductivity, can improve the Temperature Distribution of battery pack, make full use of capacity, meet the work of battery
It is required that.Therefore, it is following main electrokinetic cell cooling technology that phase-change material, which is used for battery thermal management system,.Battery was being applied
Cheng Zhong, using forcing cooling and phase-change material to cool down by the way of being combined, the heat of absorption is distributed.
Utility model content
The purpose of this utility model is to provide a kind of battery module cooled down based on air and phase-change material, the electric power storage
Pond module can improve heat-sinking capability, ensure the performance, security and life-span of battery.
To achieve the above object, the utility model employs following technical scheme：
A kind of battery module cooled down based on air and phase-change material, including some single batteries and it is arranged on two
Concurrent flow aluminium flat conduit between individual single battery.Some microchannels are offered on the concurrent flow aluminium flat conduit；The microchannel
Including several as the microchannel of air flow channel and several microchannels filled with phase-change material.It is two neighboring to be filled with phase
At least one microchannel as air flow channel is separated between the microchannel of change material.
Further, the concurrent flow aluminium flat conduit is attached on the side of single battery by insulating spacer, and concurrent flow
The length of aluminium flat conduit is equal to the length of single battery, and the height of concurrent flow aluminium flat conduit is equal to the height of single battery.
Further, the module also includes being used to force the fan for blowing air flow.
From above technical scheme, the utility model makes electric power storage by the way that phase-change material is applied in battery thermal management
When module temperature in discharge process in pond reaches the phase transition temperature of phase-change material, stored by the latent heat of phase change of phase-change material to absorb
Battery module liberated heat is simultaneously stored in the form of latent heat, so as to realize the control to temperature, is reduced in battery pack
Temperature difference, reduces the formation of local hot spots, effectively prevents battery thermal runaway, improves the service life of battery module.This
Utility model can ensure the uniformity of each battery temperature in module.The concurrent flow aluminium flat conduit that the utility model uses, has matter
The advantages that amount is light, and thermal conductivity is good, corrosion resistance is strong, the purpose of radiating can be reached.

Fig. 1 is structural representation of the present utility model；
Fig. 2 is the positional structure schematic diagram of single battery and concurrent flow aluminium flat conduit；
Fig. 3 is the length, width and height schematic diagram of single battery.
Wherein：
1st, single battery, 2, concurrent flow aluminium flat conduit, 3, air flow channel, 4, microchannel.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
A kind of battery module cooled down based on air and phase-change material as Figure 1-Figure 2, if including dry battery
Monomer 1 and the concurrent flow aluminium flat conduit 2 being arranged between two single batteries 1.Offered very on the concurrent flow aluminium flat conduit 2
Multiple microchannels；These microchannels part is used for filling phase-change material, and remaining microchannel is then what is not all filled, and is used as
Air flow channel.That is, the microchannel includes two types：Several are as the microchannel 3 of air flow channel and several
Microchannel 4 filled with phase-change material.At least one conduct is separated between the two neighboring microchannel 4 filled with phase-change material
The microchannel 3 of air flow channel.It is used as the microchannel 3 of air flow channel by being opened up respectively on concurrent flow aluminium flat conduit 2 and is filled with
The microchannel 4 of phase-change material, and between making the adjacent microchannel 4 filled with phase-change material at least one as air flow channel
Microchannel 3, this mode can phase-change material store latent heat of phase change and single battery heat pass through force pair
The mode of stream is dispersed into air.Because phase-change material has different melting temperatures, according to the needs of actual use, choosing can be passed through
The phase-change materials of different melting points is selected to meet job requirement.Air is sent into from the downside of battery module, upside discharge, such as Fig. 1
In air intlet and air outlet slit shown in.
Further, the concurrent flow aluminium flat conduit 2 is attached to by insulating spacer on the side of single battery 1, and parallel
The length for flowing aluminium flat conduit 2 is equal to the length of single battery 1, and the height of concurrent flow aluminium flat conduit 2 is equal to the height of single battery 1
Degree, it is this to be designed to make full use of space, increase contact area, strengthen heat exchange.The concurrent flow aluminium flat conduit 2 and battery
The flush of monomer 1.Two sides of concurrent flow aluminium flat conduit 2 are attached to two single batteries 1 by insulating spacer respectively
On side.The insulating spacer, play a part of insulating and attach.
Further, the module also includes being used to force the fan for blowing air flow.
On the basis of air flow cooling is blown using fan pressure and is radiated, the utility model also uses phase transformation material
Material is cooled down, and is effectively increased heat-sinking capability, be ensure that the performance, security and life-span of battery.In two electric power storages
Concurrent flow aluminium flat conduit is set between the monomer of pond, and several are set respectively as the micro- logical of air flow channel on concurrent flow aluminium flat conduit
Road and several microchannels filled with phase-change material（Phase-change material is sealed in microchannel）, so design, can either carry
The heat-sinking capability of high battery module, and can enough avoid phase-change material occur in phase transition process excessive deformation, leakage the problems such as.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New scope is defined, and on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to this
The various modifications and improvement that the technical scheme of utility model is made, the protection of the utility model claims book determination all should be fallen into
In the range of.
