Description
Background technology
High-tension battery, such as lithium battery are used as energy accumulator in electric vehicle or motor vehicle driven by mixed power.It is such
Lithium battery（Li ion batteries）Cooled down or temperature adjustment by means of cooling agent.For this reason, battery or battery list pond its bottom and/or
Side is contacted with coldplate, and the coldplate can realize that export heat is used to cool down or supply heat for heating.It is such cold
But plate is manufactured by metal, such as aluminium mostly, and configuration has inner flow passage and entrance female connector or outlet female connector.
It is proved to be unfavorable, is engaged by the coldplate that different components is formed in the prior art.This causes
Unfavorable manufacturing process and cause relatively long process duration on energy.This is associated with high manufacture cost.
20 2,012 102 969 U1 of DE disclose a kind of battery cooling apparatus, and plurality of cooling tube connects in order to heat
Opposite battery is touched by pretension.
From known in 20 2,012 101 076 U1 of DE：Carry out battery, the battery in particular for motor vehicle and coldplate
Contact, coolant hose is inserted into coldplate and mechanically pretension.
The content of the invention
According to the present invention, set it is a kind of be used to manufacturing be used to cooling down battery, in particular for motor vehicle battery cooling
The method of device, wherein two plates being made of elastic material connect each other in order to construct the device for the cooling duct being connected with each other
Close.
Dependent claims show the preferable expansion scheme of the present invention.
Therefore, the method according to the invention provides the cooling duct being connected with each other, and the cooling duct for example can be with shape
Into grid or network structure.Here, cooling duct forms the cooling tube of softness.Therefore, by means of side according to the invention
Method, it is described cold in a very simplified manner it is possible that simply and cost-effectively manufacturing the cooling duct of labyrinth
But the requirement that passage has high feature and various geometry can be adapted.In this way, for instance it can be possible that realize
Cranky shape or fork the device of cooling duct.Therefore, the flowing guiding for passing the coolant by cooling duct can be with
It is designed so that cooling duct extends along preferred orientations on each single pond of battery in structure.Also may be used according to the present invention
Can, the device for the cooling duct for making to be connected with each other dimensionally builds so that can not only realize to each single pond and/or whole
The bottom coohng of a battery and can realizing cools down the side in each single pond and/or whole battery.Therefore, from cooling duct
Device made in accordance with the present invention obtain flowing guiding can realize easily and cost-effectively very much.It is because whole
A device is all manufactured by elastic material, so the device can simply and cost-effectively come more for example in services
Change.Manufacture method according to the invention can also realize the device from different cell apparatus, battery size and/or each single pond
Quick and flexible adaptation and scale.
According to the present invention, here it is particularly advantageous that cooling duct by isolating device before engaging process by being incorporated into plate
Between and produce.By this way, particularly simply it is possible that realize the various of the device of cooling duct and
Complicated geometry.Isolating device prevents the engagement along the cooling duct to be produced in the plate engagement of elastic material,
And it is very simple and reliable measure.In addition, this method step can also automate in a straightforward manner.
According to the present invention it is possible that before splicing or after splicing removing the following region of plate, in the area
Domain should not construct cooling duct.Therefore, can require to fit with various according to the geometry and material of plate, the present invention
Match somebody with somebody.
According to the present invention, the device of cooling duct is constructed with least one inlet region and with least one outlet area,
So as to realize that cooling duct is connected in cooling agent circulation.Here, inlet region and outlet area for example may include union piece
It is or similar.
According to the present invention, cooling duct is made from a plastic material, is manufactured by elastomeric material or manufactured by metal foil.Important
It is that the material is soft so that after the device manufacturing of plate engagement and cooling duct, these cooling ducts can fill
There is cooling agent or passed through by coolant flow.Here it is particularly advantageous that the material is thin and heat conduction well.Therefore, according to this hair
The cooling duct of bright manufacture or the device of cooling duct with coolant flow through when expansion and treated with battery or battery list pond
The surface of cooling is neatly adapted to.This also makes the installment work to the device according to the invention become easy, because cooling duct
Device can be inserted into an undeployed state（einlegen）.By filling, cooling duct reaches its net shape, and
And heat transfer can be caused by the contact with battery or battery list pond.According to the present invention, the not only side in battery or battery list pond
The bottom surface in face and battery or battery list pond can be contacted by the device of cooling duct.It is flexible, according to the present invention make
The cooling duct made also with corresponding contact surface be adapted to so that the overall design of heat management system can be reduced to a small amount of parameter and
It can be simplified whereby.Here, according to the present invention it is also possible that the standardization ruler of the device using the hose-like of cooling duct
It is very little.
Obtained in the method for the device from the cooling duct according to the invention being connected with each other for manufacture of the present invention
Another important advantage is drawn in the following way：The device of cooling duct is not applied in power so that in power transmission and cooling
Between uncoupling be possible.For this, here it is particularly advantageous that battery arrangement is in following grid case, the device quilt of cooling duct
It is incorporated into the grid case.Such grid case preferably can by plastic manufacturing, such as by means of injection or by means of pressure
Cast to manufacture.Here, grid box structure carrying battery list pond or battery, or support cooling made in accordance with the present invention at the same time and lead to
The device in road.
Preferably, grid case is equipped with least one guide groove, for accommodating the device of cooling duct.It ensure that through this：Cooling is logical
The device in road carries out exactly during installation.Therefore, the event of flex point or other closings for causing cooling duct can be excluded
Barrier.
Due to cooling duct device with coolant flow through when swell, obtain good contact to battery and good
Heat deflection.Whereby, according to the present invention it is also possible that being smaller sized to contact zone and/or using being smaller sized
Cooling duct.
Diversified modification-and change possibility is obtained in terms of the material of elastic plate, it is proposed, according to the invention, cooling duct
Device by the elastic plate material be molded.In this way, for example it is also possible that using packing material, so as to improve thermal conductivity or
Person is to improve mechanical strength.In this way, for example can be with additional metal particle or plastic optical fibre.Also it is possible that by metal
Surface is coated on elastic plate, to improve mechanical surface intensity.
The method according to the invention another important advantage is that：The device for the cooling duct being connected with each other provides realization
The possibility of the cooling duct of varying cross-section.In this way, for instance it can be possible that Qu Heliu is flowed into construct with the cross section of bigger
Go out area, than middle bonding pad.
In addition, it is possible that using different cooling agents, for example with liquid or gaseous state in manufacture method according to the invention
The cooling agent of form.
