It connects, but the fluid flow that outside liquid managing device is passed through multiple pipelines is fixed.In battery pack in different battery modules
Battery cell work operating mode it is different, fixed nonadjustable flow does not adapt to the heat pipe of the battery cell of different conditions
Reason.
In view of this, as shown in Figures 1 to 5, the embodiment of the present application provides a kind of heat management connector 100, it is applied to electricity
Pond module, the battery modules include multiple battery cells 201, and multiple heat management pipelines 202 are provided in the battery modules,
The heat management pipeline 202 is for being heated or cooled the battery cell 201 by heat management liquid, the heat management
For connector 100 for the heat management pipeline 202 to be connected to exterior line, the heat management connector 100 includes joint body 101
With deformation component 102.
Detailed, the joint body 101 includes liquid feeding end 111, outlet end 112 and connection 111 and of liquid feeding end
The flexible joint 113 of outlet end 112, the liquid feeding end 111, outlet end 112 and flexible joint 113 form liquid flow all
Road.
The deformation component 102 includes two compression plates 121 being oppositely arranged and is arranged between the compression plate 121
Deformation component 102, the deformation component 102 includes thermo-sensitive material 122, and the thermo-sensitive material 122 and the compression plate 121 connect
It connects, between the thermo-sensitive material 122 is used to shrink to change between the compression plate 121 when ambient temperature is less than preset temperature
Away from so that the compression plate 121 compresses the flexible joint 113, reducing the flow in the heat management connector 100.
Deformation larger material when thermo-sensitive material 122 can select to expand with heat and contract with cold, such as can be the materials such as memorial alloy.
Thermo-sensitive material 122 will not be shunk when ambient temperature is higher than preset temperature, when ambient temperature is less than preset temperature, heat
Quick material 122 can be shunk.Thermo-sensitive material 122, which shrinks the power generated, can act on compression plate 121 so that two compressions
Plate 121 is close to each other, and compression plate 121 close to each other can apply pressure to flexible joint 113, make flexible joint 113
Internal fluid flow paths are compressed, and the flow of compressed fluid flow paths will be reduced, and flow through heat management connector 100
Liquid will also reduce.
When thermo-sensitive material 122 is under contraction state, if ambient temperature has been increased over preset temperature, thermo-sensitive material
122 contraction state can be changed into swelling state, and the thermo-sensitive material 122 under swelling state will not apply to compression plate 121
Pulling force, two compression plates 121 move in the direction away from each other under the active force of the thermo-sensitive material 122 of expansion, two compressions
Spacing between plate 121 increases, and after spacing increases to certain distance between two compression plates 121, two compression plates 121 are to soft
Property interconnecting piece 113 no longer apply pressure, flexible joint 113 restores normal condition, the flow of internal fluid flow paths
Restore to normal condition, when being compressed compared to flexible joint 113, the flow bigger of fluid flow paths is connect by heat management
First 100 fluid floies for entering battery modules internal duct compare the also bigger of flow when flexible joint 113 is compressed.
In the embodiment of the present application, the battery cell 201 in battery modules can be cylindrical battery, be set in battery modules
The liquid line set can be flat tube, and flat tube can be metal, plastics or other materials.Cylindrical battery in battery modules is simultaneously
Row arrangement, flat tube winding inside battery modules form S types.Flat tube is in contact with battery cell 201, can be with battery cell
201 carry out heat exchange.The liquid of outside liquid managing device output is entered by external pipe, the connector in flat tube,
After liquid completes heat exchange in flat tube with battery, is flowed out from the other end of flat tube, enters back into outside liquid managing device,
Complete the cycle of liquid.
When implementing, multiple battery cells 201 are set in battery modules, one or more flat tubes are pacified according to presets
Between battery cell 201, the inlet of all flat tubes passes through the heat management connector 100, external pipe and outside liquid
Managing device is connected to, and the liquid outlet of all flat tubes is connected to by other connectors with outside liquid managing device again so that outer liquid
Body managing device output liquid can be entered in flat tube by external pipe, heat management connector 100, liquid in flat tube with
Battery cell 201 carries out heat exchange.In the embodiment of the present application, the liquid of outside liquid managing device output can be temperature compared with
Low liquid cools down to battery cell 201 by outside liquid managing device.When carrying out cooling processing, battery cell
201 are typically under working condition, and the temperature of battery cell 201 is higher.At this point, the heat of the higher battery cell of temperature 201
It can be transferred to thermo-sensitive material 122, thermo-sensitive material 122 is in expansion or reset condition when temperature is higher than preset temperature, at this time
Spacing between two compression plates 121 remains stationary or compared with reset condition spacing bigger.Flexible joint 113 will not be pressed
The compression of contracting plate 121, the flow that the liquid of flat tube is entered by heat management connector 100 are in normal discharge.
In refrigerant liquid carries out process of refrigerastion to battery cell 201, the temperature of battery cell 201 can continue to decline, and wait for
After being fallen to a certain temperature at a temperature of battery cell 201 in battery modules, due to heat management connector 100 installation position closer to
Battery cell 201, the influence of the temperature of battery cell 201 to thermo-sensitive material 122 are more direct.It is reduced in 201 temperature of battery cell
In the process, with the reduction of 201 temperature of battery cell, the temperature on 122 periphery of thermo-sensitive material also accordingly reduces.It was reduced in temperature
Cheng Zhong, thermo-sensitive material 122 can change from swelling state or normal condition to contraction state.Thermo-sensitive material 122 is in contraction process
In, drive compression plate 121 close to each other, compression plate 121 close to each other applies pressure to flexible joint 113, makes through overheat
The flow for managing the refrigerant liquid of connector 100 is reduced.Refrigeration of the flat tube of flow reduction to battery cell 201 in contact
Effect will accordingly weaken.
Outside liquid managing device to battery modules in carrying out process of refrigerastion, if using ordinary couplings and battery modules
In flat tube connection, after the refrigeration effect of battery cell 201 reaches expected, when needing to reduce the supply flow of refrigerant liquid,
Outside liquid managing device, which can only be unified to reduce, supplies the liquid of all flat tubes connected to it.Such way to manage cannot
Realize the thermal management of fining.In a battery modules, multiple flat tubes are often set, the battery contacted with different flat tubes
The working condition and refrigeration effect of monomer 201 are entirely different.If using unified way to manage, it is clear that be unable to specific aim
Carry out thermal management.For example, in battery modules positioned at module centre battery cell 201 due to radiating condition compared with
Difference, the Wen Sheng that the Wen Sheng of the battery cell 201 in centre compares the battery cell 201 on module periphery are higher, module weeks
The battery cell 201 on side temperature under refrigeration reduces faster, if outside liquid managing device is according to module periphery
The refrigeration situation of battery cell 201 is if the supply that a certain time point reduces refrigerating fluid, although the liquid supply reduced can fit
Answer the operating mode of module periphery battery cell 201.But the supply of such smaller refrigerant liquid is for the electricity in module centre
It is unconformable for pond monomer 201, because the battery cell 201 in module centre is since refrigeration effect is poor, temperature
There are no be reduced to acceptable range.Obviously, it is that cannot meet module centre battery to reduce refrigerant liquid supply at this time
What the refrigeration of monomer 201 required.
In the embodiment of the present application, the multiple flat tubes being arranged in battery modules can pass through the heat management connector 100
It is connect with outside liquid managing device, the flow of each flat tube internal liquid can pass through corresponding heat management connector 100
It is respectively controlled.The flow that outside liquid managing device externally exports can remain constant, the corresponding heat management of different flat tubes
Connector 100 can make different changes according to the temperature of the battery cell 201 on respective periphery.For example, the work in battery modules
Make under state, the corresponding heat management connector of the flat tube to freeze for the battery cell 201 to position among battery modules 100
Middle thermo-sensitive material 122, heat management corresponding with the flat tube to freeze for the battery cell 201 to battery modules peripheral part
The expansion or shrinkage variation degree of thermo-sensitive material 122 in connector 100, the two is entirely different.
Intermediate position battery cell 201 is larger since temperature rises, when the flow quantity that needs normally to freeze is freezed, peripheral portion
The flat tube of position has needed to reduce refrigeration night flow.In face of such situation, using the unified thermal management mould of existing connector
Formula cannot adapt to.In the embodiment of the present application, such situation, the temperature-sensitive of the heat management connector 100 at intermediate position are faced
Material 122 due to induction be intermediate position battery cell 201 higher temperature, be in swelling state or normal condition.
At this point, compression plate 121 is not compressed flexible joint 113, the heat management connector 100 at intermediate position is still within normally
Flow supply status.At this point, in battery modules the heat management connector 100 of peripheral part thermo-sensitive material 122 incude be periphery
The thermo-sensitive material 122 of the lower temperature of position battery cell 201, peripheral part may be at contraction state so that peripheral portion
The flexible joint 113 of the heat management connector 100 of position is compressed, and the flow of the flat tube of peripheral part accordingly reduces.By using
Heat management connector 100 in the embodiment of the present application can pass through according to the practical refrigeration situation of different parts battery cell 201
The contraction of thermo-sensitive material 122 adjusts the flow of the liquid to freeze.So that the flow of multiple flat tubes in same battery modules
It can control respectively, realize the precision management of battery modules thermal management.It may be implemented to avoid lasting larger refrigerating fluid
While the normal work for coping with battery cell 201 of body adversely affects, the electricity to needing persistently to freeze may be implemented
The lasting refrigeration of pond monomer 201.
In a specific embodiment, the deformation component 102 further include be arranged it is hard between the compression plate 121
Matter cavity, the hard cavity are set in outside the thermo-sensitive material 122.In the embodiment of the present application, setting thermo-sensitive material 122 is
Wish that the expansion or shrinkage by thermo-sensitive material 122 changes the spacing between compression plate 121.But thermo-sensitive material 122 expansion or
If there is no limit if in contraction process, it is likely that in the direction expansion or shrinkage for being parallel to 121 place plane of compression plate.This
If sample, it just can not effectively change the spacing between compression plate 121.By the way that hard cavity is arranged, and thermo-sensitive material 122 is set
It sets in hard cavity, it, can only be to hard cavity since the limitation of hard cavity makes thermo-sensitive material 122 in deformation process
Interior gap deformation.Hard cavity realizes the limitation nyctitropic effect of 122 shape of thermo-sensitive material, in order to realize hard cavity to heat
While 122 deformation direction of quick material limits, regulatory function of the thermo-sensitive material 122 to 121 spacing of compression plate is not influenced.Hard chamber
Spacing between when the thickness of body can be less than two 121 confined states of compression plate, two compression plates 121 are in thermo-sensitive material
When close to each other under 122 adjustment effect, hard cavity do not interfere between two compression plates 121 just very close to.
It is understood that when implementing, rectangular, the temperature-sensitive between two compression plates 121 can be arranged in compression plate 121
Material 122 can be arranged two groups, and two groups of thermo-sensitive materials 122 are separately positioned on the both ends in 121 gap of compression plate.In compression plate 121
After being assembled with joint body 101, two groups of thermo-sensitive materials 122 are located at the both sides of flexible joint 113.Hard cavity can be set
Be set to the form of cylindrical sleeve, cylindrical sleeve is set in outside thermo-sensitive material 122, make be when 122 deformation of thermo-sensitive material to by
The direction expansion of nearly compression plate 121, or shunk to the direction far from compression plate 121.If being not provided with hard cavity limitation heat
The deformation direction of quick material 122, thermo-sensitive material 122 may will produce parallel when external temperature changes and generates deformation
In the deformation of 121 place plane of compression plate, such deformation can neither increase the spacing that can not reduce between compression plate 121,
To lose adjustment effect of the thermo-sensitive material 122 to compression plate 121.By the way that hard cavity is arranged so that thermo-sensitive material 122 exists
Deformation can only be carried out in deformation process within the scope of the limitation of hard cavity, the extending direction of the cavity of hard cavity can be vertical
In 121 place plane of compression plate so that the thermo-sensitive material 122 of hard inside cavity occurs in deformation perpendicular to compression plate 121
The deformation of place plane applies active force to realize to compression plate 121, and realization increases or reduces spacing between compression plate 121
Effect.
In another embodiment, described as shown in fig. 6, the deformation component 102 further includes multiple hard connecting rods
Thermo-sensitive material 122 is fixedly connected by the hard connecting rod with the compression plate 121.Thermo-sensitive material 122 is changed by deformation
Spacing between compression plate 121, as previously mentioned, thermo-sensitive material 122 can directly be connected with compression plate 121, such setting
Mode may may require that the thermo-sensitive material 122 using volume bigger.In order to reduce the usage amount of thermo-sensitive material 122, do not reduce
To the adjustment effect of compression plate 121, thermo-sensitive material 122 can pass through hard connecting rod and connect with compression plate 121 thermo-sensitive material 122
It connects, the deformation of thermo-sensitive material 122 can be transferred to compression plate 121 by hard connecting rod.In addition, the hard cavity can be with
It is set in outside the hard connecting rod and thermo-sensitive material 122, hard connecting rod and thermo-sensitive material 122 is limited by hard cavity
The direction of motion.
When implementing, one group of thermo-sensitive material 122 is connect by two hard connecting rods with compression plate 121 respectively, temperature-sensitive material
One end of material 122 is connect by a hard connecting rod with a compression plate 121, and the other end of thermo-sensitive material 122 is too sad another
Hard connecting rod is connect with another compression plate 121.It is in intermediate thermo-sensitive material 122 in this way in deformation, so that it may with by temperature-sensitive
The active force that 122 deformation of material generates is transferred to compression plate 121 by hard connecting rod.When thermo-sensitive material 122 expands, temperature-sensitive
Material 122 pushes the hard connecting rod at both ends to move in the direction away from each other, and then pushes compression plate 121 to being located remotely from each other
Direction moves.When thermo-sensitive material 122 is shunk, thermo-sensitive material 122 pulls the hard connecting rod at both ends to direction close to each other
Movement, and then two compression plates 121 is pulled to be moved to direction close to each other.
The deformation component 102 further includes at least one connecting plate, and described connecting plate one end is connect with the hard cavity,
The other end with the battery cell 201 for being in contact.In the embodiment of the present application, thermo-sensitive material 122 is according to surrounding enviroment
Temperature carry out deformation, it requires, in fact, thermo-sensitive material 122 is deformed upon according to the temperature of single battery.Connecting plate can be adopted
It is made of the good conductor material of the heat such as metal, one end that connecting plate is contacted with battery cell 201 in an assembling process can be with electricity
The battery cell 201 of suitable position is in contact in the module of pond, and the heat of battery cell 201 can be faster transferred to by connecting plate
Thermo-sensitive material 122 in deformation component 102, so that according to the temperature conditions of battery cell 201 shape can occur for thermo-sensitive material 122
Become, to adjust the traffic conditions of heat management connector 100.
In conclusion the heat management connector 100 in the embodiment of the present application is by being arranged compression plate 121 and thermo-sensitive material
122, the state of flexible joint 113 can be changed by the deformation of thermo-sensitive material 122, heat management connector is adjusted to realize
The effect of 100 flows so that the heat management connector 100 can be flowed through according to the adjustment of the poikilothermism in battery modules
