Description

Tempering. Battery system and electronic component

The present invention relates to a tempering and Batteriesyste me and electronic components having such a temperature control. Such tempering are used in particular as tempering for

Battery systems used in electric vehicles and the like.

It is known to produce such tempering of metals. For this purpose, two plate-shaped metal blanks are usually laid one above the other and at least peripherally fluid-tightly connected to each other. Channel structures are formed between the two metal blanks, through which a temperature control, which acts as a coolant or heating means depending on the operating state, can flow. These channel structures are defined for example in the form of embossed into the metal blanks channels.

The metallic layers of these tempering plates are usually welded or soldered to the fluid-tight connection. It is also known to manufacture such tempering plates from plastics, in particular from two plastic layers, in particular by means of hot stamping and to connect the two plastic layers peripherally with each other in a fluid-tight manner. The channel structures in which the least one temperature control medium can flow are usually already introduced during hot stamping in this case.

The plastic layers of these tempering plates are usually welded or glued to the fluid-tight connec tion.

It is also known to produce such tempering plates from a metal layer and a plastic layer. Here, the metal layer may be embossed, but not necessarily. The channel structures may be formed exclusively or at least partially in the plastic layer. The metal layer and the plastic material layer are usually connected or adhesively bonded to form a fluid-tight connection.

In the prior art large plates are used as tempering plates. However, large temperature plates are very difficult and expensive to manufacture in one piece. Therefore, it is also common in the art to produce smaller, unconnected single tempering plates and to arrange them, for example, in a tub construction or frame construction, partially together with the battery modules disposed thereon, individually.

If many individual tempering modules are used which are not connected to each other, such a composite tempering plate has only a low structural rigidity. However, if a large base plate is used as part of the tempering plate, an error in the production of the tempering plate directly leads to a uselessness of the entire tempering plate. This solution therefore has a high reject risk. This reject risk is reduced when using a large number of small, non-interconnected temperature control plates, as each of the temperature control plates can be tested for dimensional accuracy and fluid tightness before it is finally installed. On the other hand, it is desirable to provide the temperature control plate with a high structural rigidity, so that this can contribute to the overall rigidity of the Batte riemoduls.

Object of the present invention is therefore to provide a tempering, in particular special depending on the operating conditions for cooling and heating temperature control plate, as well as their use in Batteriesyste men or electronic components available that can be easily and inexpensively manufactured and on the other hand has high structure rigidity. Furthermore, it is the object of the present invention to provide a temperature control plate whose size is scalable.

This object is achieved by the tempering according to claims 1 and 4, the battery system according to claim 23 and the electronic component according to claim 25. Advantageous developments of the tempering according to the invention, the battery system and the electronic component are given in the dependent claims.

The tempering plate according to the invention now has a first planar tempering element and a second flat tempering element. It is also possible to add further tempering elements to the tempering plate according to the invention, so that the size of the tempering plate, which is constructed from the individual flat tempering elements, is scalable. This modular construction of the tempering plate according to the invention ensures high modularity and scalability.

The individual tempering elements have, as in the prior Tech technology, two layers which are arranged adjacent to one another perpendicular to their planar extension, d. h., Plain are arranged one above the other with more or less parallel flat expan sion.

The two layers of each tempering are advantageously along its peripheral edge, possibly spaced from its peripheral edge, fluid-tightly connected to each other, so that the two layers enclose an interior, which can be traversed by a tempering fluid. For this purpose, depending on the tempering optionally an inlet and an outlet for the tempering, for example, an inlet nozzle and an outlet, ordered to. The region in which the layers of a tempering element are connected to one another in a fluid-tight manner is also referred to as a sealing region.

Essential for a first variant of the tempering according to the invention is that the first and the second tempering are rich connected in a Verbindungsbe, in which the first layer of the first tempering and the second layer of the second tempering overlap each other at least in sections. This can be done, for example, by the first layer of the first tempering along one of the edges of the first tempering over the second layer, while the second layer of the second tempering protrudes along one of its edges on the first layer. If now the two he mentioned edges arranged side by side, so the first layer of the first tempering and the second layer of the second tempering can overlap each other.

Alternatively, for example, it is also possible that the first layer of the first tempering is inserted into an intermediate space between the first layer and the second layer of the second tempering or over two (all) layers of the second tempering.

In the connection region thus defined, the first layer of the first tempering element and the second layer of the second tempering element are connected to one another in a material-locking manner, at least in sections. As connec tion offers in particular welding, soldering or gluing.

Further tempering elements can each be arranged in the same way on further sides of the first or the second tempering element, in which case adjoining tempering elements in the layer plane are connected to one another in a material-locking manner in a corresponding connection region. This makes it possible to create a tempering plate with large dimensions nen by these is assembled from individual smaller tempering. Due to the cohesive connection, aims that results in a cohesively connected uniform position over the ge entire surface of the temperature control, at least two adjacent tempering. By this contiguous construction results in a high structural rigidity, which conditions, for example, when used in Fahrzeu gene leads to a lower stress on the components under conditions Betriebsbedingun and improves the crash behavior.

It is particularly advantageous that the individual tempering due to their smaller dimensions compared to the entire tempering a simpler and cheaper to manufacture and can be individually tested before Ver connection to the tempering on tightness and dimensional stability, since in addition each individual tempering separately for itself fluidly ge is. This reduces the reject risk, while the overall size of the temperature control plate is basically unlimited. In particular, the overall size of the temperature control plate in the transverse and longitudinal directions in the layer plane of the temperature control can be extended by further tempering. Overall, therefore, results from the present inventive tempering an overall module with any scalable dimensioning and high structural tursteifigkeit.

The connecting region, in which the first layer of the first tempering and the second layer of the second tempering at least partially overlap each other, must not durchgän gig in the same way along the side edge of the first layer of the first tempering or the side edge of the second layer of the second tempering , In particular, an overlap of the ers th position of the first element on the second layer of the second element and an overlap of the first layer of the second element on the second layer of the first element alternately along the course of the side edge of the first layer of the first tempering or the side edge of the second position of the second tempering take place.

In the connection region, in particular where the two tempering elements are materially interconnected, the first and the second layer of the first tempering element and the first and the second layer of the second tempering element are advantageously located respectively. to each other. The same also applies to the sealing region in which the least two layers of a tempering element are fluidly connected to each other along its outer edge. By contrast, the layers in the flow area do not lie on top of each other but span channels. To form here as well as in other embodiments between the layers of each tempering a fluid-tight tempering, which can be flowed through by a fluid form one or both of the layers of each tempering circumferentially along its peripheral edge at least from section to a bend, a backsplash or, especially with layers of plastic, have a thickening. In the following, these structures are also referred to summarily as a channel-final transformation, ie transformations which contribute to the formation of the channel or its lateral boundary in the particular embodiment.

If one or more of the tempering elements does not only consist of two layers, but if it also has further layers, for example third or fourth layers, then the tempering elements can also be configured in such a way that further layers of adjacent tempering elements overlap in the connection region. Advantageously, in the case of a tempering element with three or four layers, it is possible in particular to overlap all layers of both tempering elements with one another in the connection region and to join them together in a material-locking manner. This results in a particularly structurally rigid connection point.

In a second variant of the tempering plate according to the invention, the connecting region between a first planar tempering element and a second planar tempering element is formed by arranging in or on the connecting region a strip-shaped connecting element extending along the connecting region, for example a sheet metal strip or a plastic strip. wherein the Verbindungsele element in turn is then in each case cohesively connected to the adjacent Temperierelementen. This also results in a coherent continuous tempering with high structural rigidity of individual, simple and inexpensive to produce tempering.

Advantageously, the strip-shaped connecting element can be used in the Bonding area are embedded so that it does not protrude beyond the Oberflä surfaces of the adjacent tempering. For this purpose, one or more of the layers may be recessed in the connection region in the tempering elements, such that the strip-shaped connection element can be inserted into the recess. Alternatively, the layers adjacent to the strip-shaped connecting element Aufkan lines or have cranks, so that they together a groove ausbil the, in which the strip-shaped connecting element is arranged. These structures are hereinafter referred to collectively as connection-related to formations, ie deformations that contribute in the respective form of execution to the formation of the connection area.

The connecting element itself may have at least in sections or even continuously a rectangular cross section or a U-shaped cross-section. When using a U-shaped cross-section increase the aufgekanteten edges of the connecting element, the Längsbiegestifig-- speed of the connecting element on. The connecting element may be formed of metal or plastic, wherein a connecting element made of plastic, for example, may be extruded. In particular, when a Ver connecting element made of plastic is used, a greater variety of shapes for the connecting element is possible, such as a multi-ribbed profile or a honeycomb structure. Hollow profiles are possible.

The height of the groove or the height of the recess perpendicular to the plane of the layers of the tempering may be greater than, equal to or less than the height of the connecting element.

The strip-shaped connecting element can also be configured such that it additionally has a perpendicular to its planar extension extending the web, which additionally increases the structural rigidity of Verbindungsele Mentes. The connecting element can be designed for this purpose, for example, in T-shape or in L-shape.

The connecting elements described can not only be used to connect adjacent tempering with each other. You can also nen at least partially or even completely around the Outer edge of the tempering be arranged circumferentially on the tempering to. This can be done in a simple manner, in particular, if the tempering rich not only in the described Verbindungsbe, but also in the angren not to further tempering Zenden edges are formed so that one of the layers of the outer tempering on the other (n) position ( n) of the tempering protrudes. In the projecting area, not only a further tempering element can then be added if required, but also, for example, one of the stripe-shaped elements described above. This further increases the structural rigidity of the entire temperature control plate, in particular in its edge regions.

Advantageously, one, several or all layers of the two tempering made of metal, in particular sheet metal, in which case Alumi niumblech is preferred. Most sheet metal thicknesses between 0.2 and 2, in particular 0.4 to 1.2 mm are used. Alternatively, steel, in particular stainless steel can be used, then in particular sheet thicknesses of 0.1 to 1.5 mm are possible. However, they can also consist of a plastic, in particular a thermoplastic, advantageously a polyamide (PA), in particular PA 4.6, PA 6, PA 6.6, PA 6.10, PA 6.12, PA 11, PA 12, and / or a polyphthalamide (PPA), a polycarbonate (PC), a polyetheretherketone (PEEK), a polypropylene carbonate (PPc), a polyphenylene sulfide (PPS), a polypropylene homopolymer (PPh) or a polybutylene terephthalate (PBT) as a single material or as a blend of at least one of aforementioned materials. In this case, a plastic with an additive for increasing the thermal conductivity, for example ceramic particles and / or fibers, in particular of aluminum oxide and / or beryllium oxide, is preferred here, at least for the side facing the battery. The said layers do not have to consist entirely of these materials, but they may also have le diglich at least partially. In this case, the two layers of a tempering element together form a flow region for tempering fluid in their intermediate space and are connected to each other in a fluid-tight manner along their peripheral edge in order to seal the flow region to the outside. On the other hand, the cohesive connection of the tempering elements to the tempering plate does not have to be fluid-tight. The cohesive connection, which, as already described, in particular by welding, soldering or gluing, can be formed in particular as a weld, in particular as a continuous seam, as a point seam and / or as a stitching. It is not only possible to connect the adjacent tempering by means of a single seam. A double seam or other multiple seam, even in any combi nation with one of the aforementioned seam shapes, is possible. If the United bond, however, by means of soldering, the connection is usually over at least a slightly wider surface, in particular with at least 2 mm, preferably, at least 3 mm wide, preferably at least one of the layers is coated in advance with a suitable solder. Alternatively, a connection Ver also linear or punctiform possible by at least one caterpillar or a plurality of dots or patches of a suitable solder is applied in advance. Similarly, adhesive bonds can be flat, linear or punctiform. In this case, welded joints for the connection of metallic layers are preferred, but metallic layers can also be connected by means of soldering or gluing. In the connection of plastic fabric layers with each other, as well as plastic layers with metal layers, adhesive joints or welded joints are possible.

To further increase the structural rigidity of the tempering plate according to the invention, one or more of the layers of tempering, in particular in the connection region, embossed Struktu Ren, for example, stiffening beads and the like, have. Also, the aforementioned strip-shaped connecting elements or edge-mounted stiffening elements may have such embossed structures for further stiffening of the temperature control.

The tempering need not necessarily be adjacent to each other with respect to the respec gene in the layer plane adjacent to each other layers. It is also possible that mutually adjacent layers are arranged directly in the La with an intermediate gap. The gap can in particular have a uniform width. Here, the adjacently arranged Au ßenkanten adjacent layers preferably have a maximum distance A, especially in the connected sections, of A <5 mm, preferably A <2 mm. The average distance between adjacent edges given case plus their roughness thereby form the maximum distance A. Age natively, however, is also a flush arrangement in the layer plane adjacent ter layers of adjacent tempering possible.

Perpendicular to the layer plane adjacent layers of different tempering or even the same tempering additional Lich to the cohesive connection and form-fitting with each other a related party, for example, by clinching, folding, riveting, plugging, locking, gear cutting or screwing. Also, the arrangement of a separate hinge or the formation of a hinge in one or common sam in both of the layers is possible.

With a suitable design of the tempering louder identical Temperierelemente can be used for the formation of the temperature and arranged adjacent to each other in the longitudinal and transverse directions and stoffschlüs sig are connected. This is particularly possible if the temperature control elements are designed such that they are designed to be complementary on opposite sides. For example, it is advantageous in wesentli chen rectangular tempering when at gegenüberlie ing sides of the tempering one side is formed such that the first layer projects beyond the second layer, while the opposite side is formed such that the second layer on the first layer surmounted. The tempering element can also be configured on the sides that are orthogonal to one another and opposite one another. In this case, results in a tempering, which in the transverse and longitudinal direction in simp che way (modular) can be extended. For efficient production of the temperature control while optimally using space, it is possible for example, in the inner region of the Temperierplatte a variety identically designed, in particular rectangular Temperierelemente, enforce and make the outer region at least partially with thereof at least partially different basic shapes of tempering. In this case, it is then also possible to design the layers of the tempering elements of the outer region in such a way that a substantially flush closure of the two layers with each other is produced towards the outside. In the edge regions of a tempering element, which are designed such that they can be used for a connection region, it is not only possible, as described above, to arrange stiffening elements or connecting strips. Such areas, for example, areas in which a position of the tempering over the adjacent layer is about, can also be used for the arrangement of supply lines for supplying the tempering with tempering. Such Ver supply lines can be, for example, flat tubes, via which a temperature control can be supplied and removed. Starting from the sen supply lines then fluid connections can be supplied to the individual tempering with the tempering. By he inventive design of edge regions of the tempering, as described above for the connection areas, it is possible to subsequently install the supply lines on the finished tempering on site, for example, to weld or form-fitting order.

In the following, some examples of tempering plates according to the invention are given. In this case, the same or similar Liche reference numerals are used for the same or similar elements, so that their description may not be repeated.

In the following examples each tempering according to the invention are shown. These are for example for tempering, especially for cooling and if necessary. Heating of battery systems, in particular special traction batteries, or of electronic components, such as circuit breakers used. The examples have a variety of wesent union and a variety of purely optional features. The purely optionala len features can serve not only in the Kombinatio shown there nen to improve the tempering according to the invention, son countries also singly or in any combination with the features shown in the respec conditions example or in other examples.

Figure 11 is a side view of a battery system according to the invention with a tempering plate according to the invention; and Figure 12 is a side view of an electronic construction according to the invention part with a tempering according to the invention.

FIG. 1 shows a tempering plate 1 in an oblique view, which has two tempering elements 10a and 10b. Corresponding tempering plates 1 are shown in FIG. 11 in a battery system 100 according to the invention and in FIG. 12 in an electronic component 200 according to the invention, the plan views in FIGS. 11 and 12 being directed respectively to the side edge 99 of the tempering plate 1 in FIG.

The two tempering elements 10a and 10b of the tempering plate 1 are substantially rectangular in shape and are joined together along one of their outer edges 9a, 9b. Each of the two tempering elements 10a and 10b has a first upper layer 11a or 11b in the plan view and a second upper layer 12a or 12b in the plan view. In the case of the first tempering element 10a, the first layer 11a projects beyond the second layer 12a on two opposite sides, while the second layer 12a projects beyond the layer 11a on the other two sides which are opposite one another. In the case of the second tempering element 10b, the second layer 12b projects beyond the first layer 11b on all four sides.

Each of the tempering 10a and 10b is provided with an inlet port 15a and 15b and an outlet 16a and 16b, on the tempering, which depending on the operating state, the cooling or heating, for example, an electrochemical system, in the space between the first layer 11a 11b and the second layer 12a, 12b of the respective temperature control element 10a and 10b can be introduced and led out of it again. The layers 11a, 11b, 12a, 12b are shown here for simplicity as flat layers, the tempering 10a and 10b but each have channels that serve to guide the tempering. For this purpose, all of the layers 11a, 11b, 12a, 12b may have mutually facing recesses or only one of the layers of a tempering element may have recesses. Along one of the outer edges 13a, 13b, 14a, 14b of the temperature elements 10a and 10b, the two temperature elements 10a and 10b are arranged together, so that the first layer 11a of the first temperature element 10a projects beyond the second layer 12b of the second temperature element 10b. This supernatant 17 forms a connection region 18, in which the first layer 11a and the second layer 12b are cohesively connected to one another (welded seam not shown).

FIG. 1B shows the detail Z designated in FIG. 1A in an enlargement. In Figure 1B, 19 designates a weld, which was introduced from the upper outer side of the first layer 11a and the first layer 11b ago in the Verbindungsbe rich 18, so that in the connecting region of the 17 was over the first layer 11a of the first tempering 10a and the second layer 12b of the second temperature control element 10b are interconnected materially. In this example, the weld is a single seam that extends rectilinearly along the adjacent outer edges 13a, 13b of the first layers 11a and 11b as well as along the adjacent outer edges 14a, 14b of the second layers 12a and 12b. By this cohesive connection of the layers 11a and 12b, a continuous one-piece layer is formed, which contains these two layers 11a and 12b. Such a one-piece layer has a higher structural rigidity than non-cohesively with each other connected layers of different tempering. By this type of connection so a temperature control 1 is created with increased Struktursteifig speed. Advantageously, the individual tempering elements 10a and 10b can be produced individually. Because their dimensions are smaller than those of the entire finished tempering plate, their manufacture can be carried out in a simple and cost-effective manner, in particular on existing production plants. The individual temperature-control elements 10a and 10b can furthermore be tested for dimensional accuracy and fluid-tightness before connection, so that only temperature-control elements that are fully in line with the requirements are connected to a temperature-control plate. The tempering plates produced in this way therefore have a greatly reduced reject risk.

FIG. 2 shows a multiplicity of connection variants in the connection area 18 between two temperature control elements 10a and 10b, wherein the cross section shown corresponds to that designated in Figure 1A with AA net is. The width of the section shown here corresponds to the region Y shown in the middle in FIG. 1A.

In Figure 2, various variants of inventions to the invention tempering 1 are shown in the sub-images A to I.

In FIG. 2A, the layers 11a and 12b overlap each other as shown in FIG. In addition, the second layers 12a and 12b each have a channel-terminating offset 21a, 21b, so that remote from the connection region 18, the second layers 12a, 12b of the first layers 11a and 11b are spaced apart and a fluid space 22a in the temperature control element 10a and a fluid space 22b is clamped in the temperature control element 10b. For the fluid-tight connection of the layers 11a and 12a or the layers 11b and 12b, the layers 11a and 12a are connected to a weld 20a, and the layers 11b and 12b to a weld 20b verbun the, along the outer periphery of the temperature control elements 10a and 10b fluid circulate tightly. The seam 19 for connecting the ply 11a to the ply 12b does not have to be made fluid-tight, but serves primarily for mechanical stabilization by materially bonding the plies 11a and 12b. However, a fluid-tight connection is possible. As it does not depend on the fluid-tight connec tion in this example, can be used as a weld

19 a point seam, stitching or the like can be used. In the sem example, all layers 11a, 11b, 12a and 12b are materially connected mitei each other, so that the temperature control plate 1 has a high structural rigidity. All layers of this embodiment consist of aluminum umblech an aluminum alloy of Group 3 and have a thickness of 0.8 mm.

FIG. 2B shows a tempering plate 1 in the cutout, which is designed like that in FIG. 2A. However, the welds 20a and 20b are replaced by solder joints 20a ', 20b'. Thus, in the example of FIG. 2B, a tempering plate 1 with metallic layers 11a, 11b, 12a and 12b, more precisely a tempering plate 1 made of aluminum sheets, is concerned. FIG. 2C shows a further embodiment of a tempering plate 1 in cross section and in the cutout. In contrast to the temperature control plate in Figure 2, which is formed in otherwise the same way, the layers 11a and 11b and the layers 12a and 12b each with a gap 23a and 23b spaced voneinan. By the three welds 19, 20a and 20b, moreover, all layers of this temperature control are materially interconnected, so that the structural rigidity of the entire Temperierplatte 1 despite the column 23a, 23b is only slightly smaller than in the embodiment form of Figure 2A.

FIG. 2D shows a temperature control plate 1, which is designed like the one in FIG. 2C. In contrast to the tempering plate 1 of Figure 2C, however, the welds 20a and 20b are replaced by solder joints 20a 'and 20b'.

FIG. 2E shows a temperature control plate 1, which is designed like the one in FIG. 2C. In contrast to that in Figure 2C, however, now the two layers 11a and 11b in the illustrated cross section flush aneinan the fitting.

FIG. 2F shows a tempering plate 1 like that in FIG. 2E. In contrast to the tempering of Figure 2E, however, the Schweißverbin applications 20a and 20b are replaced by solder joints 20a 'and 20b'.

Figure 2G shows a further tempering plate 1 according to the present inven tion, which is formed as that in Figure 2F. In contrast to the tempering plate 1 of Figure 2F, however, now the welded joint 19 is replaced by a solder joint 19 '. The solder joint 19 'and the solder joint 20b' go into each other or show only a minimum distance. The solder joints 19 ', 20a', 20b 'can thereby be created ge, for example, that the layers 12a, 12b are coated in their raised areas full area with a suitable solder and after Zusammenfü conditions of the layers 12a, 12b with the layers 11a, 11b in a continuous furnace ver be. FIG. 2H shows a variant of the tempering plate 1, in which the first layers 11a, 11b each consist of a flat aluminum sheet of group 5 with a sheet thickness of 0.6 mm, while the second layers 12a, 12b consist of a thermoformed thermoplastic material with added ceramic particles , Here, no beads are introduced, but the channels 22a, 22b are formed as a recess in the plastic body, so that the side facing away from the first layers 11a, 11b surface of the second layers 12a, 12b is substantially smooth. The channel-like depressions have kanalab closing side walls 21a ', 21b' as thickenings. The connection 19 "between the first layer 11a and second layer 12a or first layer 11b and two ter layer 12b is here an adhesive bond.

FIG. 21 shows a variant of the temperature control plate 1, which corresponds predominantly to that of FIG. 2A. However, the welded joint 19 is replaced in the lappbereich over 17 by two welded joints 19 a, 19 b, which are respectively introduced at the joints of the first layers 11 a, 11 b and the second layers 12 a, 12 b, so that the layers of the same count dull each other and on the adjacent, overlapping position of other count are welded. Unlike in the preceding subfigure of Figure 2 no reference numerals 13a, 13b, 14a, 14b are now drawn here, since the outer edges of the layers 11a, 11b, 12a, 12b are covered ver by the welded joints 19a, 19b.

FIG. 3 shows a further temperature control plate 1 like that in FIG. 1. In contrast to the temperature control plate 1 of FIG. 1, the first layer 11a projects beyond the second layer 12a only along one of the outer edges of the temperature control element 10a, namely in the connection region 18 in sections. In the areas lying between these sections, the layer 12a projects beyond the layer 11a. Also, the layer 11b of the second tempering element 10b is only in sections over the layer 12b alternately with a projection of the layer 12b on the layer 11b over. If the projections are suitably arranged, the result is a connection region 18, in which the first layer 11a alternately overlaps the second layer 12b (1st section) and the first layer 11b overlaps the second layer 12a (2nd sections). Along this connection region 18, the two tempering elements 10a and 10b are provided with at least one weld seam which is not shown in subfigure A. is connected.

FIG. 3B shows a detail of the connecting region 18 in a first variant, in which a weld seam 19 extends in a straight line along the connecting region 18 and alternately connects the first layer 11a to the second layer 12b and the first layer 11b to the second layer 12a.

FIG. 3C shows a second variant of the embodiment of the connection of the tempering elements 10a and 10b. Here, the individual seam 19 from FIG. 3B is replaced by a double seam 19a, 19b.

FIG. 4 shows a further tempering plate 1 according to the present invention, which is designed like the one in FIGS. 3A and 3B. The alternating overlaps of the layer 11a over the layer 12b and the layer 11b over the layer 12a are also substantially trapezoidal. However, the side edges of the respective trapezoids are oriented in a different direction, so that there are undercuts between the individual overlapping areas, which connect the layers 11a and 11b and the layers 12a and 12b in the respective layer plane form-fitting manner.

The connection of the layers of the tempering 10a and 10b is formed with a single weld 19, this weld is not common, but has individual sections, each exclusive Lich extends within one of the trapezoidal overlap regions, the seam can thus basically referred to as stitching become.

Figure 5 shows in the subfigures A to I, another embodiment of the inventions to the invention tempering 1 in different variants. In the section shown, the upper and lower layers, with the exception of the sub-figures F and G, are each flat, but outside the region shown, at least in one layer, embossed regions follow, which serve to form channels for guiding the tempering fluid. The Temperierplatte 1 of Figure 5A in turn has two tempering 10a and 10b, each of a first upper, here metallic, flat portion shown in the section 11a and 11b and a lower, here also metallic, in the section shown flat layer 12a or 12b or include this. 5A shows only a section around a connecting region 18. In FIG. 5A, the first layers 11a and 11b and the second layers 12a and 12b abut one another directly, with the layers 11a and 12a and the layers 11b and 12b being flush with one another the temperature-regulating element 10a or 10b. The tempering elements 10a and 10b thus abut one another flush with the first layers 11a and 11b and the second layers 12a and 12b. On the first layers 11a and 11b, a strip-shaped, metallic connecting element 30 (here a sheet metal strip) is applied in the connecting region 18, which extends perpendicular to the plane of the drawing along the perpendicular plane extending to the drawing area. This Ver connecting element 30 is connected to two welds 39a and 39b, which just if perpendicular to the plane extending, with the layers 11a, 12a of the first tempering 10a and the layers 11b and 12b of the second tempering 10b materially connected. By means of this strip-shaped element, the two tempering elements 10a and 10b are connected to each other in such a way that they form a continuous rigid structure of the temperature control plate 1. All layers of this embodiment hen best of aluminum sheet of an aluminum alloy of Group 3 and have a thickness of 0.8 mm. The connecting element is made of the same alloy, but has a thickness of 1.2 mm.

FIG. 5B shows a detail of a temperature control plate 1, which is designed similarly to that of FIG. 5A. In contrast to the temperature control plate 1 in Figure 5A, the layers 11a and 11b, however, do not extend to the flush contact point between the layers 12a and 12b, but instead leave the connection region 18 free. In this released region between the layers 11a and 11b, in turn, a strip-shaped connec tion element 30 is embedded, which is materially connected to the second metallic layers 12a and 12b by means of welds 39a and 39b. The outer edges of the layers 11a and 11b delimit in the section shown from the flush to the outer edges 35a, 35b of the connecting element 30. The layers 12a and 12b thus form together with the strip-shaped ele ment 30 a structurally rigid unit. The element 30 has perpendicular to the La genebene of the temperature control plate 1 has a greater thickness than the thickness of the layer 11 a or the layer 11 b and is therefore on these layers 11 a and 11 b on. FIG. 5C shows a further embodiment of the temperature control plate 1 corresponding to that in FIG. 5B. In contrast to the tempering plate 1 in Figure 5B, the strip-shaped element is now not provided with a thickness greater than that of the layers 11a and 11b. Rather, the thickness of the strip-shaped connecting element 30 is less than the layer thickness of the layers 11a and 11b. The perpendicular to the plane of the drawing edges 35a, 35b of the strip-shaped element 30 are now more up to the outer surface of the layers 11a and 11b folded up. This Aufkantungen 31 a and 31 b additionally stiffen the strip-shaped element 30 in the longitudinal direction.

FIG. 5D shows a further embodiment of the temperature control plate 1 corresponding to that embodiment of FIG. 5B. In contrast to the embodiment of FIG. 5B, the two first layers 11a and 11b are now provided with connection-related deformations, namely, cranks 24a and 24b, so that they lie on the side of the strip-shaped element 30 opposite the layers 12a and 12b via the strip-shaped element 30 extend. This makes it possible to provide welds 39a and 39b which connect the first layer 11a or 11b to the strip-shaped element 30 and further to the second layers 12a and 12b. In FIG. 5D, the layers 11a and 11b end at a distance from each other above the strip-shaped element 30. However, it is also possible for the first layers 11a and 11b to end flush with one another.

FIG. 5E shows a further embodiment of the tempering plate 1 according to the invention similar to that in FIG. 5C. In contrast to the embodiment in FIG. 5C, the first layers 11a and 11b are now folded upwards in the direction away from the second layer 12a or 12b. Both Aufkantungen both the layers 11 a, 11 b and the marginal Aufkan lines 31 a, 31 b of the strip-shaped element 30 terminate aligned with each other. The Aufkantungen 31 a and 31 b are connected by further welds 39 a 'and 39 b' with the connection-related Aufkantungen 24 a and 24 b of La conditions 11 a and 11 b. The outer edges 13a, 13b, 35a, 35b each have Weil of the second layers 12a, 12b away. FIG. 5F shows a further temperature control plate 1, which is designed similarly to that in FIG. 5C. In contrast to the temperature control plate 1 in FIG. 5C, however, the layers 11a and 11b have cranks 21a / 24a and 21b / 24b, which are arranged starting from the connection region 18 in such a way that the layers 11a and 11b extend from the layers 12a and 12b, respectively 12b Remove. These Kröpfun conditions 21a / 24a and 21b / 24b are at the same time kanalabschließende and connec tion-related transformations. Starting from the connecting portion 18 are opposite to the cranks 21a / 24a and 21b / 24b opposite and ansons th identically formed cranks 21a 'and 21b' in the layers 11a and 11b provided, the cranks 21a 'and 21b' have only kanalabschließende function. The cranks 21a / 24a and 21a 'lead here to Ausbil tion of a full bead in the position 11a and the cranks 21b / 24b and 21b' to form a full bead in the situation 11b. These full corrugations can serve as fluid channels 22a, 22b for conducting tempering fluid through the tempering elements 10a and 10b. The strip-shaped connecting element 30 has sim i lar as in Figure 5C lateral perpendicular to the plane extending to edgings 31a and 31b, which rise to the height of the thus formed and adjacent to each of these Aufkantungen 31a and 31b arranged beads.

FIG. 5G shows a further variant of the temperature control plate 1, which forms similarly to the one in FIG. 5F. The strip-shaped connecting element 30 is now not provided with Aufkantungen. Instead, it has a thickness which corresponds to the elevations generated by the adjacent full beads in the layers 11a and 11b.

As in FIG. 5F, the full beads in the layers 11a and 11b also generate cavities 22a and 22b in FIG. 5G which serve, for example, as tempering channels for the flow of the tempering fluid for cooling or heating the temperature control plate 1. Since here no further, namely sealing weld connects the layers 11a and 12a or 11b and 12b, it is neces sary here that the cohesive connections by welds 39a and 39b not only produce a mechanical connection of adjacent layers of the tempering 10a and 10b, but also a fluid-tight closure of the gap between the layers 11a and 12a and between the layers 11b and 12b. Alternatively, however, it would also be possible to near 39a, 30b to be used only for mechanical fastening and the layers 11a and 12a or 11b andl2b separately welded tightly.

FIG. 5H shows a variant of the temperature control plate 1, which is designed like the variant of FIG. 5A with respect to the first and second layers 11a, 11b, 12a, 12b and the fastening element 30. It differs from this in that instead of two welded joints 39a, 39b, a weld joint 39 is sufficient to connect all the elements present in the section shown. The weld joint is thereby introduced so that it is located directly at the junction of the first layers 11a and 11b and the two th layers 12a and 12b and based on their extension from left to right approximately in the middle of the fastener 30 ends. This made it possible in particular, the first and second layers belonging to one another, that is, for example, the first layer 11a and the second layer 12a to be finished so that no lateral projection is formed, so that identical parts can be used for all tempering elements and the tempering plate on their Outside edge has no lateral projection of a layer. Instead of the single weld 19, two separate welds could also be used here, i. comparable to the variant of FIG. 5A.

FIG. 51 shows a variant of the temperature control plate 1 in which the first and second layers 11a, 11b, 12a, 12b and the fastening element 30 are made of synthetic material. The first and second layers 11a, 12a and 11b, 12b of a tempering are in this case by means of an adhesive layer together ver prevented. The fastening element 30 has a wave profile on its surface facing away from the tempering elements 10a, 10b. The attachment of the fastening element 30 to the tempering 10a, 10b takes place here via an adhesive connection 39 ". While the variant shown without a direct adhesive connection between tween the two tempering 10a, 10b gets along, such an adhesive bond for additional stabilization is quite possible.

FIG. 6 shows a further embodiment of a tempering plate 1 in an off-cut view. FIG. 6 shows, with the partial figures 6A to 6C, three variants of this temperature control plate 1. FIG. 6A shows a tempering plate whose construction corresponds to that in FIG. 5A, but here the connection is based on a solder joint, not a welded joint. In addition, the layers 11a and 12a or 11b and 12b are fluid-tightly connected to each other outside the area shown.

FIG. 6B shows a temperature control plate 1 which corresponds to that in FIG. 5B. Again, the analogy is limited to the structure. The connection is made differently by means of soldering. Furthermore, the strip-shaped element 30 in the figure schematically illustrated stiffening beads 31a to 31b, which extend transversely to the longitudinal direction of the connecting element 30 and cause a transverse stiffening of the connecting element 30. However, the soldering is done only in sections.

FIG. 6C shows a further variant of the tempering plate according to the invention. This corresponds largely to that in Figure 5B and derjeni conditions in Figure 6B.

In contrast to FIG. 5B, however, the strip-shaped element is connected to the layers 12a and 12b not via a weld but via a solder joint. This extends to both sides of the strip-shaped element 30 also in the area in which the layer 11a rests on the layer 12a and the layer 11b on the layer 12b. This solder joint therefore also binds the layers 11a and 12a or the layers 11b and 12b. As a result, the layers 11a, 12a, 11b, 12b and the strip-shaped connecting element 30 are connected to form a mechanically uniform overall arrangement, which has a large longitudinal bending stiffness. Advantageously, the solder joint is designed so that the layers 12a, 12b are coated on their facing to the layers 11a, 11b and the strip-shaped element 30 surface with a solder.

In contrast to Figure 6B, the strip-shaped element 30 now has no cross beads, but longitudinal beads 32a and 32b, stiffen the streifenför shaped element in the longitudinal direction. Again, the soldering is done only from sections in the contact areas. FIG. 7 shows a further embodiment of a tempering plate 1 according to the invention. The tempering plate 1 in turn has two tempering elements 10a and 10b which each have an upper layer 11a or 11b and a lower layer 12a or 12b. In a Verbindungsbe area 18, the layers 11a and 11b on the adjacent layers 12a and 12b over. The layers 11a and 11b are spaced from each other is arranged, wherein the distance of the layers 11a and 11b by their projections over the layers 12a and 12b is smaller than the distance between the layers 12a and 12b. In the connection region, therefore, a T-shaped connecting element 30 is arranged, the strip-shaped base 33 is positively inserted between the layers 12 a and 12 b and rests on the lower surface of the layers 11 a and 11 b. This strip-shaped base 33 is connected via welding seams 39a and 39b to the layers 11a and 11b, respectively, on both sides of the web 34, which lifts off quite angularly and runs perpendicular to the plane of the drawing. The web 34 causes a high longitudinal stiffening of the elongated member 30. It protrudes through the opening which is released between the two spaced layers 11a and 11b. Overall, this results in a modification of the strip-shaped connecting element by Hinzufü supply of a vertical web 34, which rises centrally in Figure 7 from the strip-shaped base 30. However, the arrangement of the vertically arranged web 34 on the strip-shaped base 33 can be chosen arbitrarily.

At the edge of the first tempering element 10a, the layer 11a protrudes beyond the layer 12a in a similar manner as the layer 11b does with respect to the layer 12b of the second tempering element 10b in the connection region 18. In other words, the tempering 10a is symmetrical with respect to the perpendicular to the plane extending right and left Außenrän the. At the supernatant of the layer 11 a on the layer 12 a, a stiffening element 40 may be arranged, which has for example an L-shape. The stiffening element 40 has for this purpose a strip-shaped base 42, which is connected in the manner described above by means of a weld 39c or via other connection techniques with the layer 11a cohesively. Starting from this strip-shaped base 42 rises perpendicularly an upstand 41 in the form of a web 43. The angular Versteifungsele element 40 extends perpendicular to the plane of the drawing along the edge of the layer 11 a of the first tempering 10 a and leads to a stiffening this peripheral edge. Such a stiffening element can be provided circumferentially around the tempering plate in suitable design of the tempering elements around the entire tempering plate or else in sections. As a result, it is also possible to compensate for a projection of a layer over another layer, here the layer 11a over the layer 12a, so that the risk of injury when handling the tempering plate 1 or the tempering elements 10a, 10b is reduced.

FIG. 8 shows a temperature control plate 1 in a plan view similar to that in FIG. 1. This temperature control plate is shown without connections for fluid and also without fluid spaces in the two temperature control elements 10a and 10b. The omission of these elements in the figure 8 is used to better explain the fiction, contemporary design of the connecting portion 18th

In the connection region 18, which is shown in an additional enlarged section in FIG. 8, the layers 11a and 12b overlap one another. The outer edges 13a and 13b extend in a zigzag line, wherein the two outer edges 13a and 13b continue to lie flush against each other. The corresponding outer edges of the second layers also run in a zigzag line, which is indicated by the dashed line. The weld 19 extends straight through the region in which the layers 11a and 12b overlap with each other. In this way, the two layers 11a and 12b and thus also the tempering elements 10a and 10b are connected to each other along a substantially continuous line. At the same time, at least in sections, the two adjacent layers 12a and 11b are also connected to one another in a materially bonded manner. As an alternative to the illustrated zigzag course of the outer edges 13a, 13b, wave-shaped courses, zigzag-shaped courses with undercuts and the like are also possible.

FIG. 9A shows a further embodiment of a temperature control plate 1 according to the present invention. The layers 11a, 12a and 11b now have cranks 25a, 25a ', 25b, so that in a connecting region 18, the edges 13a, 13b, 14a, 14b of the layers 11a, 11b, 12a, 12b in the order 11a, 11b, 12a , 12b come to lie on each other. The four layers are fully continuous with each other via a weld 19 which is perpendicular to the drawing level runs, connected. This total four-layer connection leads to a very high stiffening of the temperature control. 1

FIG. 9B shows a further variant of such a temperature control plate 1 as shown in FIG. 9A. Now, however, only the two layers 11a and 12a are provided with cranks 25a and 25a ', which, however, are formed such that the outer edges 13a, 13b of the layers 11a and 12a come to lie on the outer edge surfaces of the layers 11b and 12b. The layers 11a, 12a, 11b, 12b are in turn connected by means of a weld 19, which is perpendicular to the drawing plane, in the order 11a, 12a, 11b, 12b. The cranks 25a and 25a 'are designed so that, as seen from the connec tion region 18 from behind the cranks lying areas of the layers 11a and 12a lie in a plane with the layers 11b and 12b. The height of the cranks 25a and 25a 'thus correspond to the total thickness of the two layers 11b and 12b and thus compensate for the difference in height.

Figure 10A shows a plan view of a tempering 1 according to the present invention. This has four temperature control elements 10a, 10b, 10c and 10d. In a schematic semitransparent view through the tempering is shown in solid lines in each case the outer contour of the upper layers 11a, 11b, 11c, lld. The dotted lines represent the outer contour of the lower layers 12a, 12b, 12c, 12d. Thus, for example, the layer 11a overhangs the layer 12a on the left and upper side of the drawing, while the lower layer 12a overhangs the upper layer 11a on the right and surmounted on the lower side of the drawing. Along the supernatant of the layer 12a over the layer 11a on the lower side of the drawing, a supply module 2 with supply lines 3 and 4 is arranged. The mechanical cal connection of the supply lines 2 and 3 can be carried out in the same manner as the connection between the stiffening element 40 and the upper layer 11a in Figure 7. In other words, the Versorgungslei lines 2 and 3 can be arranged on the supernatant of the layers 12a and there with this be connected via a cohesive connection, for example, a weld seam. Starting from the supply line 3, fluid bridges 5a to 5d are arranged in the direction of the temperature control elements 10a to 10d, which terminate in connection pieces 15a to 15d of the temperature control elements 10a to 10d, which are, however, only indicated here. These serve for the supply of Temperingfluid, for example, coolant to the fluid interior in the tempering 10a to lOd. The fluid bridges 6a to 6d extend from the fluid outlet 4 in the direction of the temperature control elements 10a to 10d, where they are connected to outlet connection pieces 16a to 16d, via which the temperature control fluid can be removed from the temperature control elements 10a to 10d.

FIG. 10B shows a cross section along the line B-B in the detail X of FIG. 10A. The supply module 2 consists of two layers 2 a, 2 b, which are fluid-tightly welded to each other in the area between the supply line 3 and the disposal line 4 by means of a weld 19 b. Likewise, the layers 2a, 2b are fluid-tightly connected to one another via a weld seam 19a and to the second layer 12a of the tempering element 10a, where the lower layer 2a of the supply module 2 partially rests flat on the layer 12a and the weld seam 19 in this overlapping region into the image plane into it.

In the variant of FIG IOC, the supply module 2 is again composed of two La conditions 2 a, 2 b. Here, however, the layers of the supply module are not on a position of the tempering 10a, but limit since Lich to the side edges of the layers 11a, 12a. The connection is made to the water interface, but a connecting element 30 applied to the upper layer 2b of the supply module and the first layer 11a of the tempering 10a and the weld 19a both through the connecting element 30 and through both layers 2a, 2b of the supply element and both layers 11a, 12a of the tempering 10a ranges.

Figure 11 shows a side view of a battery system 100 according to the invention with a temperature control plate 1 according to the invention, which forms out as in Figure 1 is. The battery system here comprises a battery assembly 105 with at least eleven battery cells 110, which is brought to operating temperature via its downwardly facing flat outer side 120 by means of the adjoining temperature control plate 1 to Be operation and ge in continuous operation is cooled. But it could also at least one more row of Bat teriezellen be present behind the visible battery cells 110. While here the battery cells are oriented so that they are parallel to one another in a direction visible edge 99 are arranged one behind the other, also a vertical arrangement would be possible. Then the battery cells would be arranged one after the other in the direction of view. The dashed double-dotted line represents an optional housing 130 that surrounds the battery cells 110. If such is present, the thermal contact between the

Battery cell 110 and the temperature control plate 1 via the housing 130 formed as the bottom of the Ge outside 120 of the battery assembly 105th

FIG. 12 shows a side view of an electronic component 200 according to the invention with a tempering plate 1 according to the invention, which, as shown in FIG

1 is formed. The electronic component 200 here comprises an electronic component 210 and an electronic assembly (211), which are cooled via the outside 220 by means of the adjacent thereto tempering 1 in most operating conditions.
