Description
Technical field
The present invention relates to battery thermal management technical field, and in particular to a kind of electric power storage cooled down based on air and phase-change material
Pond 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.
The content of the invention
It is an object of the invention to provide a kind of battery module cooled down based on air and phase-change material, the battery mould
Block can improve heat-sinking capability, ensure the performance, security and life-span of battery.
To achieve the above object, present invention 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 storages
Concurrent flow aluminium flat conduit between battery cell.Some microchannels are offered on the concurrent flow aluminium flat conduit；The microchannel includes
Several as air flow channel microchannel and several be filled with phase-change material microchannels.It is two neighboring to be filled with phase transformation material
At least one microchannel as air flow channel is separated between the microchannel of 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 present invention makes battery mould by the way that phase-change material is applied in battery thermal management
When block temperature in discharge process reaches the phase transition temperature of phase-change material, battery is absorbed by the latent heat of phase change of phase-change material
Module liberated heat is simultaneously stored in the form of latent heat, so as to realize the control to temperature, reduces the temperature in battery pack
Difference, reduces the formation of local hot spots, effectively prevents battery thermal runaway, improves the service life of battery module.The present invention
The uniformity of each battery temperature in module can be ensured.The concurrent flow aluminium flat conduit that the present invention uses, there is light weight, thermal conductivity
Well, the advantages that corrosion resistance is strong, the purpose of radiating can be reached.

Embodiment
The present invention will be further described 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, including some single batteries 1
And it is arranged on the concurrent flow aluminium flat conduit 2 between two single batteries 1.Offered on the concurrent flow aluminium flat conduit 2 many micro-
Passage；These microchannels part is used for filling phase-change material, and remaining microchannel is then what is not all filled, as air
Runner.That is, the microchannel includes two types：Several are as the microchannel 3 of air flow channel and several fillings
There is the microchannel 4 of phase-change material.It is separated between the two neighboring microchannel 4 filled with phase-change material and at least one is used as air
The microchannel 3 of runner.It is used as the microchannel 3 of air flow channel by being opened up respectively on concurrent flow aluminium flat conduit 2 and filled with phase transformation
The microchannel 4 of material, and between making the adjacent microchannel 4 filled with phase-change material at least one as the micro- of air flow channel
Passage 3, the latent heat of phase change and the heat of single battery that this mode can store phase-change material pass through forced convertion
Mode is dispersed into air., can be by selecting not according to the needs of actual use because phase-change material has different melting temperatures
Meet job requirement with the phase-change material of fusing point.Air is sent into from the downside of battery module, upside discharge, in Fig. 1
Shown in air intlet and air outlet slit.
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 present invention is also entered using phase-change material
Row cooling, effectively increases heat-sinking capability, ensure that the performance, security and life-span of battery.In two battery lists
Concurrent flow aluminium flat conduit is set between body, and set respectively on concurrent flow aluminium flat conduit several as air flow channel microchannel with
Several are filled with the microchannel of phase-change material（Phase-change material is sealed in microchannel）, so design, storage can either be improved
The heat-sinking capability of battery module, and can enough avoid phase-change material occur in phase transition process excessive deformation, leakage the problems such as.
