Description

[0001] The present invention relates to a method for joining a nozzle element through which a temperature control medium can flow to a plate part having an opening for a temperature control plate through which the temperature control medium can flow. The invention further relates to such a plate part and a temperature control plate with such a plate part. Finally, the invention also relates to a battery assembly with such a temperature control plate.

[0002] Conventional temperature control plates for controlling the temperature of batteries or similar devices, through which a temperature control medium can flow, typically consist of two plate parts that are soldered or welded together. One of the two plate parts features a channel structure through which the temperature control medium can flow, while the other of the two plate parts is typically largely flat, covering the channel structure and sealing it fluid-tight. The battery to be temperature-controlled can be arranged on the cover plate, thermally coupling the battery to the temperature control medium flowing through the channel structure, allowing heat to be transferred between the temperature control medium and the battery.

[0003] Corresponding temperature control medium connections for introducing the temperature control medium into the channel structure or for discharging the coolant from the channel structure are usually welded or soldered to one of the two plate parts, which requires that a metal is selected as the material for such a temperature control medium connection.

[0004] However, both welding and soldering such temperature control connections to one of the two plate parts proves to be energy-intensive, therefore very expensive and also prone to errors, which can lead to comparatively high leak rates in series production. In addition, the material used for soldering becomes soft, so additional measures must be taken to increase strength. Furthermore, the flux used in soldering must be removed again in downstream rinsing processes, which is a complex process. During welding, the material can become soft, at least in the area of ​​the weld seam, due to heat input. A disadvantage of plate parts that are glued together is that once the plates have been glued, no further temperature control connections can be soldered or welded on, as otherwise the adhesive used to bond the two plates could be damaged by local heat input.

[0005] All of the disadvantages mentioned ultimately lead to an undesirable increase in costs in the production of the plate part with nozzle element or in the production of the temperature control plate.

[0006] It is therefore an object of the present invention to provide an improved method for producing a plate part mentioned at the outset, in which in particular the above-mentioned disadvantages are at least partially, preferably completely, eliminated.

[0007] This object is achieved by the subject matter of the independent patent claims. Preferred embodiments are the subject matter of the dependent claims.

[0008] The basic idea of ​​the invention is therefore to use a plastic material as the material for a nozzle element serving as a temperature control medium connection, not a metal, as is usual with conventional temperature control plates, and to bond such a plastic nozzle element to the plate part mentioned above by means of thermal joining. During thermal joining, the nozzle element is heated and also pressed onto the plate part. The heating melts the plastic of the nozzle element in a joining area where it is joined to the plate part, thus creating the desired bonded connection, which remains permanent and mechanically stable after the nozzle element has cooled.

[0009] Since the thermal joining process presented here does not require any soldering or welding, the aforementioned disadvantages are eliminated. Furthermore, thermal joining is significantly less energy-intensive and therefore more cost-effective than soldering or welding the nozzle element to the plate part.

[0010] Furthermore, the risk of the aforementioned undesirable strength reduction is avoided. Likewise, the removal of flux after soldering is eliminated. Furthermore, the use of plastic instead of metal for the channel plate results in a significant and advantageous weight reduction. Finally, a plastic nozzle element is also significantly more cost-effective than a metal nozzle element.

[0011] As a result, the method according to the invention presented here creates a technically very simple and thus cost-effective method for joining a nozzle element to a plate part for a temperature control plate.

[0012] Following the inventive concept explained above, the method according to the invention serves for joining at least one nozzle element through which a temperature control medium can flow to a plate part having an opening for a temperature control plate through which the temperature control medium can flow.

[0013] The method according to the invention comprises at least three mandatory measures a) to c).

[0014] In one measure a), a nozzle element made of a plastic and a plate part in which an opening is formed are provided. The opening extends from a plate top side to a plate bottom side of the lower part. For the flow of a temperature control medium through the nozzle element, the nozzle element can have the geometry of a hollow body with two, preferably opposite, openings through which the temperature control medium can enter and exit the interior space delimited by the hollow body. Preferably, the nozzle element or the hollow body can have the geometry of a hollow cylinder.

[0015] In measure b), the nozzle element is positioned on the plate part so that it encloses the opening. In this state, the nozzle element protrudes from the plate part.

[0016] In step c), the nozzle element is thermally joined to the plate part. The thermal joining process essential to the invention comprises heating the nozzle element and pressing the nozzle element to the plate part. A suitable joining tool can be used for the thermal joining process, which can in particular comprise a pressing tool for pressing the nozzle element to the plate part and a preferably electric heating device for heating the nozzle element. The pressing tool can in turn comprise a die for receiving the plate part and a punch for pressing the nozzle element to the plate part.

[0017] In a preferred embodiment of the method according to the invention, the thermal joining according to step c) is carried out without any additional material, in particular without the use of an adhesive. This eliminates the comparatively complex dosing of the additional material or adhesive, and furthermore, no additional time is required for the additional material or adhesive to cure. This leads to a significant acceleration of the manufacturing process.

[0018] According to an advantageous development of the method according to the invention, the thermal joining in step c) comprises melting the nozzle element in a joining section with which the nozzle element rests against the plate part. For this purpose, at least said joining section is temporarily heated. To melt the joining section, it is expediently heated to a joining temperature that is greater than a melting temperature of the plastic of the nozzle element. In this way, the molten plastic can form the desired solid, material-to-material bond with the material of the plate part, i.e., preferably a metal or a plastic, as soon as the temperature of the plastic has dropped below the melting temperature.

[0019] In order to melt the joining section, the nozzle element and / or the plate part in question can be heated in the area of ​​the opening to a joining temperature of at least 150 °C and / or at most 300 °C.

[0020] In a further preferred embodiment, the thermal joining in step c) comprises pressing the molten nozzle element with the plate part. In conjunction with the heating and the resulting melting of the plastic in the region of the joining section, said pressing ensures the desired fusion of the plastic of the nozzle element with the material of the plate part.

[0021] Particularly preferably, the pressing and heating can take place simultaneously, in particular synchronously or staggered. "Synchronously" means simultaneous pressing and heating, whereas the term "staggered" means that heating begins before pressing, or vice versa. By simultaneously heating and pressing the joining partners, the plastic of the nozzle element can bond particularly well to the material of the plate part forming one of the joining partners.

[0022] Alternatively, it can also be provided that the pressing takes place after the heating, i.e. in particular the joining section is first heated to the desired joining temperature and pressing only begins after the joining temperature has been reached.

[0023] According to another advantageous development, a border section of the plate part surrounding the opening is roughened prior to thermal joining according to step c). The roughening can preferably be carried out by means of a laser treatment. Such roughening improves the material bond formed between the joining section and the plate part.

[0024] Particularly preferably, the thermal joining according to measure c) is carried out in such a way that a materially bonded connection is formed between the nozzle element, in particular the joining section of the nozzle element, and the plate part. The heating of the nozzle element can thus be limited to the joining section. This accelerates the joining process. Furthermore, it is impossible for other areas of the nozzle element to be damaged by heating.

[0025] Particularly expediently, a plate material for at least the plate part provided in step a) to which the nozzle element is thermally joined in step c) can be a metal, in particular aluminum, or a plastic, in particular polyamide (PA) or polypropylene (PP). If a plastic is selected as the plate material, it proves advantageous that it can be provided with a complex geometric shape, application-specifically, in a cost-effective manner using suitable plastic injection molds. If a metal is selected as the plate material for the plate part, a material-to-material connection to the other plate part can be achieved by welding or soldering, if the material for the other plate part is also a metal.

[0026] According to an advantageous development of the method according to the invention, this comprises an additional measure z1), which is carried out either before measure a) or after measure c). According to this additional measure z1), the plate part is joined to another plate part in a material-to-material bonding manner, so that after joining, the two plate parts form a temperature control plate which delimits an interior plate space through which a temperature control medium can flow. If measure z1) is carried out before measure c), a material-to-material bonding by means of gluing, welding or soldering proves to be expedient, so that the selection can be made on an application-specific basis. If measure z1) is carried out after measure c), a material-to-material bonding by means of gluing or welding proves to be advantageous, since the temperatures occurring during soldering could damage the plastic of the nozzle element.

[0027] Particularly preferably, the plate interior through which the temperature control medium flows is formed by a channel structure in the plate part or in the further plate part. In this variant, the other plate part is designed as a cover plate which covers the plate part having the channel structure in a fluid-tight manner. The cover plate is preferably flat or even. This makes it particularly easy to arrange a battery to be temperature-controlled on the outside of the cover plate and to thermally couple it to the temperature control medium flowing through the channel structure. Particularly preferably, a metal is selected as the material for the other plate part or the cover plate. In this way, the thermal coupling of the temperature control medium to the battery to be temperature-controlled is further improved.

[0028] The invention further relates to a plate part for a temperature control plate for controlling the temperature of a battery, in particular of a motor vehicle, preferably of an electric vehicle. The plate part according to the invention comprises at least one opening formed in the plate part. At least one connecting piece of the temperature control plate made of a plastic is arranged on the plate part, which connecting piece encloses the at least one opening. The connecting piece element is thermally joined to the plate part. The above-explained advantages of thermal joining for the integral connection of the connecting piece element to the plate part are therefore transferred to the plate part according to the invention.

[0029] Particularly preferably, the plate part according to the invention is produced by means of the method according to the invention presented above, so that the advantages of the method according to the invention explained above are transferred to the plate part according to the invention.

[0030] In a preferred embodiment of the plate part according to the invention, the integral connection is formed without any filler material, in particular without any adhesive. This eliminates the need for a comparatively complex dosing of the filler material or adhesive, and also eliminates the need for additional time for the filler material or adhesive to cure. This leads to a significant acceleration of the manufacturing process.

[0031] In another preferred embodiment, the nozzle element is melted in a joining section, with which it forms the material-to-material connection with the plate part. In this way, the molten plastic can form a solid material-to-material connection with the material of the plate part, preferably a metal or a plastic.

[0032] Particularly preferably, a plate material of the plate part can be a metal, in particular aluminum, or a plastic, in particular polyamide (PA) or polypropylene (PP).

[0033] The invention also relates to a temperature control plate for controlling the temperature of a battery, in particular of a motor vehicle, preferably of an electric vehicle. The temperature control plate according to the invention comprises a plate part according to the invention presented above and also a further plate part which is integrally connected to the plate part according to the invention. The advantages of the plate part according to the invention and of the method according to the invention explained above are therefore transferred to the temperature control plate according to the invention. The two plate parts of the temperature control plate surround a plate interior through which a temperature control medium can flow.

[0034] In a preferred embodiment of the temperature control plate according to the invention, the plate interior through which the temperature control medium can flow is formed by a channel structure formed in the plate part or in the further plate part. In this embodiment, the other plate part, which is preferably designed as a cover plate, covers the plate part with the channel structure in a fluid-tight manner. Since the opening enclosed by the nozzle element communicates fluidically with the channel structure, the temperature control medium can be introduced into or discharged from the channel structure with the aid of the nozzle element. Here, too, the nozzle element functions as a connection for an external temperature control line through which the temperature control medium can flow.

[0035] Particularly expediently, a (first) plate material of the plate part can be a metal, preferably aluminum, or a plastic, preferably polyamide (PA) or polypropylene (PP). If a plastic is selected as the plate material, it proves advantageous that it can be provided with application-specific, even complex geometric shapes in a cost-effective manner using suitable plastic injection molds. If a metal is selected as the plate material for the plate part, a material-to-material connection to the other plate part can be achieved by welding or soldering, if the material for the other plate part is also a metal.

[0036] Alternatively or additionally, in this variant, a (second) plate material of the further plate part can be a metal, preferably aluminum. Since the battery to be temperature-controlled is typically arranged externally on the second plate part, a particularly good thermal coupling of the battery to the temperature-control plate can be achieved due to the comparatively high thermal conductivity of a metal.

[0037] Particularly preferably, the plate part and the further plate part can be connected to one another in a materially bonded manner, in particular by means of an adhesive, soldered, or welded connection. As explained above, a soldered or welded connection is suitable for the materially bonding of two plate parts made of one metal. An adhesive connection is advantageously considered if the material of at least one of the two plate parts is a plastic.

[0038] The invention further relates to a battery assembly for a motor vehicle, in particular for an electric vehicle. The battery assembly according to the invention comprises at least one rechargeable battery, in particular for supplying an electric drive system of the motor vehicle or electric vehicle with electrical energy. The battery generates waste heat during operation. For temperature control of the battery and in particular for dissipating the waste heat generated during operation, the battery assembly according to the invention comprises at least one temperature control plate according to the invention as presented above. Thus, the above-explained advantages of the method according to the invention and the temperature control plate according to the invention also apply to the battery assembly according to the invention.In the battery arrangement according to the invention, at least one battery is arranged on the plate part or on the further plate part of the temperature control plate for thermal coupling to the temperature control medium guided through the channel structure of the temperature control plate. In this way, effective heat can be transferred between the temperature control medium and the battery. This battery is preferably arranged on the plate part designed as a cover plate.

[0039] Further important features and advantages of the invention emerge from the subclaims, from the drawings and from the associated description of the figures with reference to the drawings.

[0040] It is understood that the features mentioned above and those to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the present invention.

[0041] Preferred embodiments of the invention are illustrated in the drawings and are explained in more detail in the following description, wherein the same reference numerals refer to the same or similar or functionally identical components.

[0042] They show, schematically: Fig. 1 a perspective partial view of an example of a tempering plate according to the invention with two plate parts, Fig. 2 a partial view of the temperature control plate of the Fig. 1 in a longitudinal section in the area of ​​a nozzle element, Fig. 3 a flowchart explaining the method according to the invention, Fig. 4 shows, by way of example and in a highly simplified manner, the basic structure of a joining tool which can be used for carrying out the method according to the invention,

[0043] The Fig. Figure 1 shows an isometric view of an example of a temperature control plate 10 according to the invention for controlling the temperature of a battery of a motor vehicle, for example an electric vehicle. The temperature control plate 10 according to the invention comprises a first plate part 1 according to the invention and also a further, second plate part 6, which is integrally connected to the first plate part 1. The second plate part 6 is shown in the illustration of Fig. 1 is largely concealed by the first plate part 1. The firm, material-to-material connection between the two plate parts 1, 6 can be provided circumferentially at least along a lateral outer plate edge 12 of the temperature control plate 1 and is then formed on a peripheral side 13 of the temperature control plate 1 formed by the two plate parts 1, 6. The two plate parts 1, 6 surround a plate interior 11 through which a temperature control medium can flow. The first plate part 1 has two openings 3 formed in the plate part 1, which communicate fluidically with the plate interior 11. On an outer side 14 of the first plate part 1 facing away from the second plate part 6, two nozzle elements 2 are arranged, each made of a plastic, for example polyamide (PA) or polypropylene (PP), which are designed to allow the temperature control medium to flow through and which each enclose one of the two openings 3.The two nozzle elements 2 are firmly connected to the first plate part 1 by a material bond and, for this purpose, thermally joined to the first plate part 1. The first plate part 1 with the two nozzle elements 2 is thus formed as a single piece. Furthermore, the first plate part 1 is manufactured using the method according to the invention, which means that the nozzle element 2 is thermally joined to the first plate part 1. The material bond between the two nozzle elements 2 and the first plate part is therefore free of additional materials and, in particular, also free of adhesives.

[0044] In the example scenario, the plate interior 11 through which the temperature control medium can flow is formed by a space in the first plate part 1 (cf. Fig. 1) or in the second plate part 6 (not shown) formed channel structure 7.

[0045] The second plate part 6, on the other hand, is designed as a cover plate 8, which covers the first plate part 1 with the channel structure 7 in a fluid-tight manner. Thus, temperature control medium can be introduced into the channel structure 7 or discharged from it again via the two openings 3 with the nozzle elements 2.

[0046] A plate material of the first plate part 1 can be a metal, for example, aluminum, or a plastic, for example, polyamide (PA) or polypropylene (PP). A plate material of the second plate part 6 is preferably a metal, for example, aluminum. In the example, the first plate part 1 and the second plate part 6 are integrally connected to one another by means of an adhesive, solder, or welded joint. A solder or welded joint requires that the plate material of both plate parts 1, 6 be a metal.

[0047] As the Fig. 1, the channel structure 7 in the example of the Fig. 1 four sub-channel structures 7a, 7b, 7c, 7d, each with meandering channels 9.

[0048] Furthermore, the channel structure 7 comprises a channel 9, 9a, which functions as a temperature control medium distributor for distributing the temperature control medium to the individual sub-channel structures 7a to 7d. Accordingly, the channel structure 7 also comprises a temperature control medium path 9, 9b, which functions as a temperature control medium collector for collecting the temperature control medium from the individual sub-channel structures 7a to 7d.

[0049] In the example of Fig. 1, two openings 3 are formed in the channel plate 1, of which a first opening 3a serves to introduce the temperature control medium into the channel structure 7, and a second opening 3b serves to discharge the temperature control medium from the channel structure 4 after it has flowed through it. For this purpose, the first opening 3a of the two openings 3 is fluidically connected to the channel 9a forming the temperature control medium distributor, and the second opening 3b of the two openings 3 is fluidically connected to the channel 9b of the channel structure 7 forming the temperature control medium collector. In variants of the example not shown, a different number of openings 3 can also be provided in the first plate part 1.

[0050] The Fig. 2 shows a partial view of the temperature control plate of the Fig. 1 in a longitudinal section in the area of ​​one of the two nozzle elements 2. Accordingly, the nozzle element 2 is melted in a respective joining section 4, with which it is thermally joined to the first plate part 1 and thus forms a material connection with the plate part 1.

[0051] In the following, the method according to the invention is explained using the flow chart of Fig. 3 by way of example. As already explained, the method according to the invention serves for joining at least one nozzle element 2 made of a plastic, through which a temperature control medium can flow, and for this purpose is preferably hollow-cylindrical, to a plate part 1 having an opening 3 for a temperature control plate 10 through which the temperature control medium can flow. The plastic of the nozzle element 2 can be polyamide (PA) or polypropylene (PP). The material of the first plate part 1 can be a metal, in particular aluminum, or a plastic, for example polyamide (PA) or polypropylene (PP).

[0052] In the example, the method according to the invention comprises three mandatory measures a), b) and c).

[0053] In measure a), the nozzle element and the first plate part 1 with the opening 3 are provided.

[0054] In a measure b), the nozzle element 2 is arranged on the first plate part 1 in such a way that it surrounds the opening 3 and protrudes from the plate part 1.

[0055] In step c), the nozzle element 2 is then thermally joined to the plate part 1. The thermal joining according to step c) takes place without additional material, in particular without the use of an adhesive. The thermal joining comprises melting the nozzle element 2 in a joining section 4 of the nozzle element 2, with which it rests against the plate part 1. For melting, the joining section 4 is heated. Likewise, the first plate part 1 can be heated at least in the region of the opening 3. The heating of the joining section 4 and the plate part 1 in the region of the opening 3 can be heated to a joining temperature of at least 150°C and at most 300°C. The joining temperature established in the joining section 4 must be at least as high as the melting temperature of the plastic of the nozzle element 2.

[0056] In addition to the heating or melting explained above, the thermal joining in step c) also includes pressing the nozzle element 2 with the plate part 1. The pressing and heating preferably take place simultaneously and in a suitable joining tool 20, which is shown schematically and in a very simplified manner in Fig. 4 shows a heatable pressing tool with a die 21 for receiving the first plate part 1, with a punch 22 for pressing the connecting piece element 2 to the plate part 1, and with an electric heating device 23. The heating device 23 can comprise a first electric heating element 24a arranged in or on the die 21 and a second electric heating element 24b arranged in or on the punch 22. In a simplified variant of the heating device 23, the first or second heating element 24a, 24b can be omitted.

[0057] Alternatively, it may also be provided that the pressing is not carried out at the same time as the heating, but rather after heating to the predetermined joining temperature.

[0058] Optionally, before the thermal joining according to measure c), a border section 5 enclosing the opening 3 (cf. Fig. 4) of the plate part 1. Such roughening can preferably be carried out by means of a laser treatment.

[0059] As shown in the flow chart of the Fig.3, the method according to the invention in the example scenario comprises an additional measure z1), which is carried out before measure a). According to this additional measure z1), the plate part 1 is joined in a material-to-material manner to another plate part 6, so that the two plate parts 1, 6, after joining, form a temperature control plate 10 which delimits the plate interior 11 through which the temperature control medium can flow. The thermal joining of the nozzle element to the plate part 1 according to measure c) therefore takes place when the second plate part 6 has already been joined to the first plate part 1. The material-to-material connection of the two plate parts 1, 6 according to additional measure z1) can be carried out by gluing, welding or soldering the two plate parts together.

[0060] In a further variant of the example, the additional measure z1 can be carried out after measure c), i.e., the joining of the two plate parts takes place after the joining of the nozzle element to the plate part 1. In this case, the material-to-material connection is preferably achieved by gluing, but welding of the two joining partners is also possible as an alternative. After the two plate parts 1, 6 have been materially joined and the nozzle element has been joined to the plate part 1 by thermal joining, the temperature control plate 10 according to the invention is completed.
