Description

[0001] The invention relates to a method for joining two components to one another, in particular battery components, by means of a multi-component, curable interface material, wherein the two components are provided as a first component and a second component and are joined by means of the interface material in such a way that the interface material is located between the components after joining and contacts a first joining surface of the first component and a second joining surface of the second component, wherein, prior to joining, a first material component of the interface material and a second material component of the interface material are each provided in a viscous state, wherein the first and second material components are such that upon contact between the first and second material components, a curing process of the first and second material components is triggered or accelerated,and wherein the first and second material components are brought into contact with each other in the viscous state to initiate or accelerate the curing process. Furthermore, the invention also relates to a component assembly, in particular a battery component assembly.

[0002] In car body construction and battery assembly, adhesives or thermally conductive fillers are often applied in bead or swirl applications, or by injection. Two-component systems are often used as fillers, which are mechanically mixed immediately before application to a component. At this point, crosslinking begins and viscosity increases. Furthermore, the components must be joined within a predefined time, also known as the open time. If joining does not occur within the predefined time frame, the required component properties will not be achieved, requiring rework or resulting in rejects.If the fillers are designed to have a very long open time to avoid such rework or scrap, it also takes a very long time to reach the so-called handling strength, at which the filler is sufficiently cross-linked or cured to enable subsequent work steps, such as assembly or other processing steps. This lengthens the manufacturing process.

[0003] DE 10 2022 113 366 A1 describes a traction battery assembly with a heat exchanger plate having a plurality of coolant channels distributed in the heat exchanger plate according to a first pattern, and with a thermally conductive material arranged on a surface of the heat exchanger plate according to a second pattern. The first pattern replicates the second pattern. When the battery pack is assembled, the thermally conductive material is arranged between the battery cells and the surface. The thermally conductive material can be a liquid thermally conductive material that cures and solidifies after a specific time interval, approximately two hours. The thermally conductive material can also be a two-component material, whereby the two parts can be combined in a specific ratio to achieve curing.

[0004] Furthermore, WO 2022 / 056096 A1 describes a two-component thermal interface material.

[0005] The object of the present invention is to provide a method and a component arrangement which enable two components to be joined together via a multi-component interface material and, on the one hand, to avoid premature curing of the interface material and, on the other hand, to enable the fastest possible curing process.

[0006] This object is achieved by a method and a component arrangement having the features according to the respective independent patent claims. Advantageous embodiments of the invention are the subject of the dependent patent claims, the description, and the figures.

[0007] In a method according to the invention for joining two components to one another, in particular battery components, by means of a multi-component, curable interface material, the two components are provided as a first component and a second component, and are joined by means of the interface material in such a way that the interface material is located between the two components after joining and contacts a first joining surface of the first component and a second joining surface of the second component, wherein, before joining, a first material component of the interface material and a second material component of the interface material are each provided in a viscous state, wherein the first and second material components are such that upon contact between the first and second material components, a curing process of the first and second material components is triggered or accelerated,and wherein the first and second material components are brought into contact with each other in a viscous state to initiate or accelerate the curing process. Before joining, the first material component is applied in a viscous state to the first joining surface, and the second material component is applied in a viscous state to the second joining surface. During joining, the first component is arranged on the second component with its first joining surface facing the second joining surface of the second component in such a way that the first material component and the second material component are brought into contact.

[0008] This advantageously makes it possible to only initiate the curing process or accelerate the curing process once the two components have already been joined or arranged next to one another. Before the two material components are brought into contact, either no curing process, which can also be referred to as cross-linking or cross-linking, takes place at all, or the curing process is very slow, effectively providing a very long "open time." In other words, there is plenty of time to arrange the two components in the intended relationship, since no curing or hardly any curing of the material components takes place before the two components are arranged next to one another and the material components are thus brought into contact with one another.On the other hand, this also enables an extremely rapid curing process after the two components have been joined, because the joining process itself brings the two material components into contact with each other, thus triggering or accelerating the curing process. This advantageously makes it possible to use material components to provide the interface material that have a very short curing time or that are designed in such a way that the time until the handling strength described above is reached is extremely short. This short curing time, or time until handling strength is reached, completely leaves the time available for arranging the two components next to each other without the material components curing during this time unaffected.The time available for arranging the two components together, i.e., until the two components are arranged as intended, and the time required after arranging the components together until handling strength is achieved or the interface material has fully cured, can advantageously be completely decoupled using the joining process described. Subsequent process steps and assembly steps can thus be carried out extremely quickly, and the production time for manufacturing a component arrangement or even a larger assembly comprising the component arrangement can be significantly shortened without having to take the risk of premature curing before the components are joined. This can reduce scrap rates, as well as the frequency of any need for rework.

[0009] In principle, any conventional material components of multi-component, particularly two-component, interface materials, such as two-component adhesives, can be used as material components of the interface material. The two material components have different properties. This means that they differ in terms of their chemical composition. One of the two material components can also be referred to as an activator, accelerator, crosslinker, booster, or catalyst. For the sake of simplicity, it is assumed below that this is the first material component, although the second material component can also represent this activator, booster, accelerator, crosslinker, or catalyst. Accordingly, the first material component is sometimes simply referred to below as a booster. Such a booster can be easily chemically matched to the desired curing time.Different curing times can thus be achieved chemically simply by modifying the composition of the booster and / or the amount of booster used in relation to the amount of the second material component. In addition, the first material component is matched to the second material component in such a way that their contact with each other triggers or accelerates the curing process or cross-linking. When the material components come into contact, a chemical reaction occurs between the material components, which triggers or accelerates the cross-linking. Material components can therefore advantageously be selected that enable a very short curing process. This is preferably in the range of seconds or minutes, but can also be selected in the range of hours if necessary and depending on the requirements.

[0010] Furthermore, the material components, or at least one of the material components, are designed to be stable in the viscous state. This preferably already has the highest possible viscosity in the viscous state. This enables particularly simple overhead assembly of the component on which this material component is arranged, without the material component dripping from the joining surface.

[0011] In an advantageous embodiment of the invention, a battery module and a housing component of a battery housing are provided as the two components, in particular wherein the housing component has a cooling plate which provides the first or second joining surface. Interface materials are often used in battery assembly in particular, for example to connect battery modules to a housing component. It is therefore precisely in this area that particularly great advantages can be achieved by the invention. Such a battery module can comprise only a single battery cell or multiple battery cells. The battery module can therefore also be, for example, only a single battery cell. Preferably, however, the battery module comprises multiple battery cells. One of the undersides of the battery module can be formed by the respective undersides of the battery cells encompassed by the battery module.This underside of the battery module, or also its top side, can provide one of the joining surfaces. The other of the two joining surfaces is provided by the housing component. In principle, it is possible for any side of such a battery module to be joined to the housing component. It therefore does not necessarily have to be a top side or bottom side of such a battery module with regard to the intended installation position in a motor vehicle. However, particularly efficient cooling of battery modules can be achieved precisely when, for example, several such battery modules are arranged on a common cooling plate and / or a common cooling cover is arranged on the battery modules. Accordingly, it is advantageous if the top side and / or bottom side of such a battery module provides one of the joining surfaces.In the following, it is assumed that the first battery cell represents the battery module and the housing component the second component. Especially when the housing component is designed as a cooling plate, it is very advantageous to connect a battery module to the housing component via the interface material, as this can prevent air pockets and free spaces between the battery module and the housing component, which would reduce the thermal connection of the battery module to the cooling plate. Furthermore, as explained in more detail later, the interface material can additionally be designed so that it also has very good thermally conductive properties. The described method can accordingly be part of a method for producing a battery. Such a battery can comprise a battery housing, which in turn has the housing component.The battery module, along with additional optional modules, can be located in the battery housing. The battery can thus be designed as a high-voltage battery for a motor vehicle.

[0012] In this application example, it is also preferred that the two joining surfaces are flat surfaces. This allows the battery module to be joined to the housing component in a particularly simple and efficient manner, and the remaining gap filled with the interface material can be reduced to a minimum. This, in turn, allows the amount of interface material required to fill this gap to be reduced to a minimum. This allows costs and weight to be saved and, above all, the thermal resistance between the battery module and the housing component to be minimized. The battery module can, for example, have a first module side that provides the first joining surface, and the housing component can have a first component side that provides the second joining surface. It is preferred that the entire first module side forms the first joining surface.In other words, the entire first module side is to be connected to the housing component via the interface material. If the two components are joined together as intended, the interface material preferably contacts the entire first side of the battery module. Such complete wetting can provide a uniform heat transfer resistance across the entire first module side and also reduce it to a minimum. The first component side of the housing component can be larger than the second joining surface. In other words, the second joining surface can also represent only a portion of this housing component side and not the entire housing component side.

[0013] According to a further very advantageous embodiment of the invention, the first and second joining surfaces correspond to one another in terms of their geometry and / or their dimensions, wherein the first material component is applied flatly to the entire first joining surface and wherein the second material component is applied flatly to the entire second joining surface. If the first component is then arranged on the second component, contact between the two material components, and above all large-area contact between the material components, can be ensured. Ideally, there should then be no areas within the respective joining surfaces with one of the material components that have no contact with the other material component. This allows the cross-linking process to be initiated particularly evenly and homogeneously across the entire interface material located between the two joining surfaces.

[0014] In this example, the application of the respective material components to the respective joining surfaces can be done by doctoring, brushing or similar.

[0015] According to a further advantageous embodiment of the invention, the first component is arranged on the second component such that the first and second joining surfaces lie congruently one above the other. This advantageously allows the material components applied to the joining surfaces to be brought into contact over a large area.

[0016] It is also conceivable, in particular, that the second material component is applied to an area of ​​the second component that is larger than and encompasses the second joining area. In other words, the second material component, especially if the second component represents the housing component, can also be applied slightly beyond the actual second joining area. These areas located outside the joining area, in which the second material component is then applied, do not necessarily have to be brought into contact with a corresponding part of the first joining area or even with the first material component at all.Applying the second material component slightly beyond the second joining area makes it easier to ensure that, when the two components are aligned, the first material component applied to the first joining surface is also fully contacted by the second material component, at least superficially. This facilitates the congruent overlap of the two joining surfaces.

[0017] According to a further advantageous embodiment of the invention, the first material component is applied to a first partial region of the first joining surface according to a first application pattern and the second material component is applied to a second partial region of the second joining surface according to a second application pattern corresponding to the first application pattern, wherein the first and the second application pattern or the first and the second partial region correspond to one another in such a way that the first application pattern and the second application pattern or the first partial region and the second partial region can be placed on top of one another in a substantially congruent manner, wherein when the first component is arranged on the second component, the first material component and the second material component are brought into contact with one another in a congruent manner.

[0018] The first partial area does not represent the entire first joining surface, but is smaller than it, and the second partial area does not represent the entire second joining surface, but is smaller than it. The two material components do not necessarily have to be applied to the respective joining surfaces over a large area, so that the respective material components do not have to completely wet the respective joining surfaces before the components are joined. In this case, however, it is advantageous if the respective material components are applied in mutually corresponding application patterns. A material component can, for example, be applied to its associated joining surface in a bead. This bead can, for example, have the shape of a straight, winding, or twisted line. The two application patterns can, for example, correspond to one another in such a way that they are axially symmetrical to one another.This allows the two application patterns to be placed congruently on top of each other when the components are arranged with their respective joining surfaces facing each other. This ensures the maximum possible contact area between the two material components when the two components are arranged next to each other.

[0019] According to a further advantageous embodiment of the invention, after the first and second material components have been brought into contact, the components are moved relative to one another while exerting pressure on the material components, whereby the contacting material components are distributed over the first and second joining surfaces beyond the first and second partial areas.

[0020] The fact that the two components are moved relative to one another can mean, for example, that the first component is fixed in terms of its position and the second component is moved towards the first component, or that the second component is fixed in terms of its position and the first component is moved in the direction of the second component, or that both components are moved towards one another. This movement can be minimal. In other words, it can be a movement of a few centimeters, in particular a few millimeters. By pressing these two components together, pressure is simultaneously exerted on the material components of the interface material located between the components. As a result, the material components are distributed over the surface and preferably cover the first and second joining surfaces essentially completely or completely.One or both of the material components can also spread across the respective joining surfaces. When pressure is applied to the material components, the two material components are already in contact with each other. This initiates or accelerates the cross-linking process. However, the material components are then preferably designed in such a way that no instantaneous cross-linking takes place, but rather the curing or cross-linking process lasts sufficiently long to distribute the material components across the first and second joining surfaces through the application of pressure. Such pressure is usually only applied for a very short time, for example in the range of seconds or minutes. This nevertheless enables a very rapid curing process and the handling strength is achieved very quickly.

[0021] However, a flat application of the material components to the respective joining surfaces, as described above, is preferred, since then no additional conditions are to be attached to the curing time and this can be selected as required by the appropriate choice of material components, for example, even extremely short, without running the risk that the joining surfaces cannot be completely wetted.

[0022] In a further advantageous embodiment of the invention, an interface material, which represents an adhesive, is formed by the contacting material components, i.e., by the first and second material components that are brought into contact with one another. The two components can thus be bonded together very advantageously and efficiently. This is particularly advantageous when the components are the aforementioned battery components, since an adhesive can provide additional structural rigidity for the overall arrangement. Additional fastening measures for attaching the components to one another, such as screw connections, can thus be reduced in number or eliminated entirely.

[0023] The interface material can also be a so-called gap filler. Unlike an adhesive, this is not designed to transfer loads. Such a gap filler, also called a gap filler, serves to prevent air pockets and gaps between the components to be joined, for example, to enable the best possible thermal connection between the two components.

[0024] According to a further advantageous embodiment of the invention, an interface material is formed by the contacting material components, i.e. by the first and second material components which are brought into contact with one another, which interface material represents a thermal interface material, in particular a thermally conductive adhesive or a gap filler. The interface material can therefore, as explained above, represent an adhesive or a gap filler and, in this case, additionally has very good thermally conductive properties. This can be achieved in a variety of ways. For example, one or both of the material components can be provided with thermally conductive particles, for example ceramic particles, metal particles or the like. The thermally conductive particles can be embedded in a matrix of the material component in question.However, a substance with good thermal conductivity can also be chosen for one or both of the material components.

[0025] In a further advantageous embodiment of the invention, a plurality of second joining surfaces are provided by the second component, wherein a respective first component of a plurality of first components, each of which has a first joining surface, is arranged on one of the second joining surfaces of the second component, in particular one after the other. The arrangement of a respective first component on the second component can take place as described above in the context of the method according to the invention and its embodiments for the first and second component. The first material component of the interface material can therefore be applied to the respective first joining surfaces and the second material component can be applied to the second joining surfaces of the second component. The first components can then be arranged on the second joining surfaces of the second component, for example simultaneously, but preferably one after the other, and optionally pressed against them.This is particularly advantageous when multiple battery modules are to be arranged on a common housing component, such as a cooling plate. The multiple second joining surfaces of the second component can also form a large overall joining surface. However, the second joining surfaces can also be spatially spaced or separated from one another. The second material component can also be applied to the respective second joining surfaces one after the other if the first components are to be arranged one after the other on the respective second joining surfaces of the second component. However, it is also possible to first provide all second joining surfaces with the corresponding second material component and then arrange the first components with their respective first material components on the second joining surfaces simultaneously or one after the other.

[0026] Furthermore, the invention also relates to a component arrangement, in particular a battery component arrangement, which was produced by means of a method according to the invention or one of its embodiments.

[0027] The advantages described for the method according to the invention and its embodiments apply equally to the component arrangement according to the invention.

[0028] The invention also includes further developments of the component arrangement according to the invention that have features already described in connection with the further developments of the method according to the invention. For this reason, the corresponding further developments of the component arrangement according to the invention are not described again here.

[0029] Furthermore, the invention also relates to a battery, in particular a high-voltage battery, with a component arrangement according to the invention or one of its embodiments and to a motor vehicle with a component arrangement according to the invention or one of its embodiments.

[0030] The motor vehicle according to the invention is preferably designed as a motor vehicle, in particular as a passenger car or truck, or as a passenger bus or motorcycle.

[0031] The invention also encompasses combinations of the features of the described embodiments. The invention therefore also encompasses implementations that each comprise a combination of the features of several of the described embodiments, unless the embodiments are described as mutually exclusive.

[0032] Exemplary embodiments of the invention are described below. Shown are: Fig. 1 a schematic representation of two components to be joined prior to joining according to an embodiment of the invention; and Fig. 2 a schematic representation of the two components joined together according to an embodiment of the invention.

[0033] The exemplary embodiments explained below are preferred embodiments of the invention. In the exemplary embodiments, the described components of the embodiments each represent individual features of the invention that can be considered independently of one another, each of which also develops the invention independently of one another. Therefore, the disclosure is intended to encompass combinations of the features of the embodiments other than those shown. Furthermore, the described embodiments can also be supplemented by further features of the invention already described.

[0034] In the figures, the same reference symbols designate elements with the same function.

[0035] Fig. 1 shows a schematic representation of a component assembly 10 prior to joining. The component assembly 10 comprises a first component 12, which may be configured, for example, as a battery module 12a, and a second component 14, which may be configured, for example, as a housing component 14a, for example, a cooling plate or a cooling cover. A two-component interface material 16 is used to join the two components. This interface material 16 is configured, in particular, as a thermal interface material 16, for example, a thermally conductive adhesive. The interface material 16 comprises two components, namely a first material component 16a and a second material component 16b. The first material component 16a is also referred to below as a booster.The two material components 16a, 16b are designed and matched to one another in such a way that the curing or cross-linking process is initiated or accelerated upon their contact. Acceleration is to be understood in particular as meaning that the curing process occurs more quickly from the contact of the two material components 16a, 16b than before the contact of the components 16a, 16b, in particular significantly faster. The speed of the curing process of the interface material 16 or of a respective component 16a, 16b of the interface material 16 can be defined by a period of time that lasts from the time of application of the components 16a, 16b to the respective components 12, 14 and / or from the time of contact of the respective components 16a, 16b with air until the time at which a certain strength of the respective component 16a, 16b or of the interface material 16 is reached.

[0036] The first component 12, in particular the battery module 12a, has a first module side 18, which can, for example, represent an underside of the battery module 12a. The battery module 12a can also comprise a plurality of battery cells. In addition, the second component 14 has a first component side 20. This can also be referred to below as the top side 20. The first module side 18 provides a first joining surface 22. Likewise, the first component side 20 provides a second joining surface 24. If the first component 12 is designed as a battery module 12a, it is preferred that the entire underside 18 of the battery module 12a simultaneously also represents the first joining surface 22. The same can also apply to the second component 14, although this is not necessarily required if the second component 14 represents a housing component 14a.In other words, the first component side 20 can also be larger in relation to its surface area than the second joining surface 24 encompassed by it.

[0037] Before the two components 12, 14 are arranged next to each other, the first material component 16a of the interface material 16 is applied to the first joining surface 22 and the second material component 16b is applied to the second joining surface 24. In Fig. 1, the components 16a, 16b are each pre-applied to a component 12, 14. It is preferred that the first material component 16a is distributed over as large an area as possible on the first joining surface 22, so that, if possible, the entire joining surface 22 is completely wetted by the first material component 16a. The same applies to the second joining surface 22 and the second material component 16b. Subsequently, the two components 12, 14 are arranged next to one another. The arrangement is shown in Fig. 1 by the arrow 26. The components 12, 14 arranged next to each other are Fig. 2 shown.

[0038] Fig.2 shows a schematic representation of the component arrangement 10 in a state in which the two components 12, 14 are now joined together or arranged next to one another. The first component 12 is arranged with respect to the second component 14 such that the first joining surface 22 lies directly opposite the second joining surface 24. In particular, the components 12, 14 were arranged next to one another such that the two joining surfaces 22, 24 lie one above the other as congruently as possible. By arranging 26 the two components 12, 14 next to one another, the two material components 16a, 16b of the interface material 16 also come into contact, whereby the curing process of the interface material 16 is triggered or accelerated. The components 14, 16 can also be pressed against one another, e.g., with a specific contact force. The two components 16a, 16b react with one another upon this contact. This reaction area is designated 26 here.This initiates or accelerates the crosslinking reaction of components 16a, 16b to form interface material 16. The two material components 16a, 16b provide the interface material 16, which now consists of the combination of the two material components 16a, 16b.

[0039] Overall, the examples demonstrate how the invention can provide a process for the open-time-independent activation, gelling, or curing of TIM (thermal interface material) by pre-application of individual components to components. The (pre-)application of the individual components and the joining of the components can be completely decoupled in time. This eliminates the need for time-controlled individual steps for producing assemblies, and disruptions or downtimes occurring in the production process result in less scrap or rework.
