Description

Technical Field

[0001] The present invention relates to a cooling system, a single modular element as part of the cooling system, and a cooling device including the cooling system. Background Technology

[0002] Many electronic circuits use electrical and / or electronic structural components that experience measurable temperature rises during operation due to power losses. Unfavorable or unacceptable temperature values ​​can be reached, particularly due to large internal line resistances and / or high operating currents, at which point the operation of the electronic circuit becomes ineffective or its functional safety is compromised, especially during its intended service life. For these reasons, heat dissipation schemes should often be provided for the temperature-sensitive areas of the electronic circuit. For very high power losses, in some applications, heat dissipation is required by means of a cooling medium within a cooling mechanism through which the temperature-sensitive areas of the electronic circuit are then connected, at least indirectly, to the cooling mechanism through which the cooling medium flows.

[0003] Electronic applications with high power consumption, such as control equipment used particularly in the automotive industry, place high demands on operational safety, making heat dissipation extremely important. Modern vehicle computers communicate internally via a high-speed bus system (backbone) on the chassis. Due to rapid development in this area, there is a frequent need for updates, upgrades, or replacements of electronic devices, both at the software and hardware levels, for use in vehicles. Consequently, there is a need and demand for flexible integration of control equipment within the automotive industry.

[0004] In the service industry, server modules are often immersed in cooling pools filled with inert coolant to dissipate heat due to high power loss. This involves stationary applications with large size and heavy weight. Similar power loss scenarios will likely emerge in the field of autonomous driving in the future. However, there is a lack of a suitable and cost-effective solution for the automotive industry that ensures the dissipation of high power loss while also allowing for easy replacement of the electronics to keep pace with the latest developments.

[0005] German publication DE602005006310T2 discloses an apparatus in which power modules are stacked and arranged in a common fluid flow. The direction of the fluid for cooling medium and the corresponding openings extend laterally to the flat extension of the power modules and their electrical connections. Furthermore, each power module provides a section of a common cooling channel for the cooling medium. Replacing the power modules is very cumbersome because the apparatus must be completely disassembled and rebuilt. This requires draining the cooling medium and re-injecting it after reinstallation. It is impossible to operate the apparatus without replacing the power modules, thus potentially forcing downtime during replacement, during which the associated electronic applications become unusable. Summary of the Invention

[0006] The objective of this invention is to reliably dissipate heat from electronic units with high power loss and to achieve rapid and simple replaceability.

[0007] This task is accomplished by a cooling system as described in this application, a single modular element as part of the cooling system, and a cooling device including the cooling system.

[0008] This invention relates to a cooling system with a closed cooling channel system, the cooling system being constructed between a main inlet and a main outlet for the cooling medium and including at least one cooling channel pipe. Here, the cooling system is formed by two or more individual modular elements, each of which includes at least a portion of the cooling channel system or at least one cooling channel pipe. Here, in the connection region between two individual modular elements, particularly in a detachable manner, at least one portion of each of the two individual modular elements is continuously connected to form at least one cooling channel pipe. Furthermore, adjacent individual modular elements in the connection region each have complementary elements of a common medium coupling, particularly constructed as a closed coupling, wherein in the detached connection between two adjacent individual modular elements, the portion of the corresponding individual modular element is medium-sealed at least in its connection region, and in the connecting connection between two adjacent individual modular elements in the connection region, the passage for the internal flow of the cooling medium through the medium coupling is open. In this way, multiple individual modular elements can be easily assembled into the cooling system. Here, existing cooling systems can be advantageously adjusted in size by adding or removing at least one individual modular element. This allows for adjustments to be made at any time in an advantageous manner without the need for cooling medium loss or refilling. In one particular embodiment, at least one or all of the individual module elements can integrally comprise an electronic unit that is at least indirectly in thermal contact with a portion of the at least one cooling channel piping.

[0009] A particularly advantageous embodiment of the cooling system is that it is constructed as a basic cooling module comprising at least one cooling channel pipe as a basic cooling channel system. This basic cooling channel system additionally has at least two additional joints, by means of which the basic cooling channel system, located outside the basic cooling module, can be extended via detachable connections to at least one cooling section of an external cooling mechanism. Preferably, in such connections, the cooling sections are connected or can be connected as parallel additional pipes relative to the basic cooling channel system, constructed between the connected additional joints. Alternatively, two separate cooling channel pipes are connected or can be connected across each other in such connections. Advantageously, the cooling sections of the different connected cooling mechanisms are thus located only indirectly through the basic cooling module in a common, subsequently extended cooling channel system, allowing each connected cooling mechanism to be easily removed from or re-embedded into the cooling system without dependence on other connected cooling mechanisms. Here, the additional joints of the basic cooling channel system within the basic cooling module, as seen from the connectable cooling mechanism, represent the sole interface for the cooling medium. In this way, easy and efficient replaceability of electronic modules throughout the cooling system is achieved, whereby the electronic modules, for example, have electronic units that are at least indirectly in thermal contact with the aforementioned connectable cooling mechanisms. The basic cooling module thus provides a distribution base for the cooling medium for one or more connectable cooling mechanisms, particularly as part of the electronic modules. When a single cooling mechanism is removed, the flow of cooling medium within the basic cooling channel system and other cooling mechanisms possibly connected to it can easily continue. This is because all exposed additional joints simply need to be sealed in a medium-sealed manner. This can be done simply, for example, by using sealing elements, which are made as plug-in seals or screw seals. Therefore, the operation of the cooling system and the heat dissipation of, for example, at least one electronic unit indirectly thermally connected to the cooling system can be maintained, and downtime of connected electronic applications can be avoided.

[0010] The basic cooling module is additionally a mechanical composite structure base, through which the cooling mechanism connected to the composite structure base can mechanically remain fixed in the composite structure. Furthermore, the necessary dimensions of the cooling system are modularly scalable by providing the basic cooling channel system within the basic cooling module. The maximum scalability is determined by the number of additional joints provided within the basic cooling channel system. The dimensions of the cooling system can then be variably or meaningfully limited according to the number of external cooling mechanisms connected and thus by the number of cooling sections of each external cooling mechanism additionally connected to the basic cooling channel system. The detachable, and particularly media-sealed, connections allow for rapid and easy scaling of the system by inserting or removing external cooling mechanisms. Any known solutions can be considered here, particularly force-transmitting connections and / or form-fit connections. Exemplary solutions include threaded connections, media-sealed plug connections, spring-supported compression connections, mating connections, and / or other detachable connection implementations. As the cooling medium, cooling gas or coolant, especially cooling water or inert coolant, is considered if electrical contact with the electronic unit to be cooled exists or cannot be ruled out according to the specified heat dissipation scheme. During operation, the cooling system is connected to a medium pump via a main inlet and a main outlet, by means of which a cooling medium flow is obtained within the cooling system, for example, in the form of a closed cooling loop. The cooling medium flows through at least one closed cooling channel pipe and / or bridging the connected cooling channel pipes inside the basic cooling module, and also flows through the connected cooling section if an external cooling mechanism is connected to a corresponding additional joint.

[0011] An advantageous embodiment of the cooling system is characterized by at least one pair of additional connectors belonging to exactly one or at least one continuous cooling channel pipe, and / or at least one pair of additional connectors belonging to exactly two or at least two separate cooling channel pipes, such that a cooling section of at least one external cooling mechanism can be connected as a parallel additional pipe to the corresponding at least one assigned cooling channel pipe, and / or the at least two assigned separate cooling channel pipes can be connected to each other across the cooling section. For the two separate cooling channel pipes, preferably one of the cooling channel pipes includes the main inlet of the cooling system and the other cooling channel pipe includes the main outlet of the cooling system. Furthermore, it is preferred that the two separate cooling channel pipes are constructed parallel to each other within the basic cooling module, wherein the main inlet and main outlet are particularly arranged in the end regions of the separate cooling channel pipes. In principle, the main inlet and main outlet can then be arranged, in particular, on the same side of the basic cooling module or, alternatively, on opposite sides of the basic cooling module. Overall, this results in a feasible solution for connecting the basic cooling module to the media pump in a relatively close manner.

[0012] For continuous cooling channel piping, it is preferable to create multiple possible parallel additional piping by a continuous arrangement of pairs of adjacent additional joints from the outside in. More preferably, the at least one continuous cooling channel piping is U-shaped within the basic cooling module, wherein the main inlet and main outlet are arranged, particularly on the same side of the basic cooling module, in the end regions of the continuous cooling channel piping. This generally ensures a high degree of compactness of the cooling system even when connected to external cooling mechanisms.

[0013] An advantageous embodiment of the cooling system is provided herein, wherein at least one or all individual modular elements have exactly two additional connectors, which can be connected to the module inlet and module outlet of an external cooling mechanism, respectively. In this respect, the number of individual modules corresponds exactly to the number of external cooling mechanisms that can be connected. Thus, the modular design is very straightforward and cost-effective in both manufacturing and operation.

[0014] In one particular embodiment of the cooling system, bridging cooling channel pipes are constructed in at least one or all individual modular elements, each bridging cooling channel pipe extending inside the individual modular element into two included sections of at least one cooling channel pipe. Here, each individual modular element has at least three additional connectors, two of which are connectable to external cooling mechanisms, such that the cooling sections of the external cooling mechanisms can be connected as additional pipes parallel to the bridging cooling channel pipes in the sections formed between the connectable additional connectors. In this way, multiple external cooling mechanisms can be utilized for expansion within the parallel additional pipes that can be connected to form a basic cooling channel system. Alternatively, a connection selection scheme is provided that allows connection of external cooling mechanisms with different connection sizes. Here, connection sizes corresponding to the spacing of two arbitrary additional connectors within the individual modular element can be achieved. Overall, this further improves the flexibility of the cooling system.

[0015] In principle, it is advantageous that, in order to obtain a mechanically held composite structure, the individual modular elements are connected in a force-transmitting and / or form-fitting manner when constructing a basic cooling module. This can be achieved, in particular, by means of a detachable connection system, including threaded connections, locking connections, plug-in connections, or clamp connections. Other detachable connection implementations are also possible.

[0016] Furthermore, in an advantageous embodiment of the cooling system, the basic cooling module has at least one fixing element configured as a complementary element to a detachable common fixing system for external cooling mechanisms, the fixing system serving to mechanically fix the basic cooling module and the external cooling mechanisms together relative to each other. The fixing system is preferably configured as a threaded connection, locking connection, plug-in connection, or clamp connection. Generally, the composite structure of the basic cooling module and one or more connected external cooling mechanisms, particularly as at least part of a motor vehicle's cooling system, can withstand mechanical forces, portions of which are subjected to dynamic loads in a constantly changing manner.

[0017] In another advantageous embodiment of the cooling system, each of the at least two auxiliary joints has a straight-through valve for the cooling medium, wherein the straight-through valve is used to: open the basic cooling channel system for cooling medium flow in a first operating position and to seal the basic cooling channel system in a second operating position. The operating position is determined here according to the connection state with an external cooling mechanism. For this purpose, the corresponding straight-through valve has, for example, an adjusting element, which is spatially arranged differently depending on the connection state. Here, in the first operating position, the internal opening of the auxiliary joint is retained to allow volumetric flow of the cooling medium, while in the disengaged state, in the subsequently occupied second operating position, the opening is locked by at least one adjusting element. The first operating position is preferably generated by the action of an operating element that is part of the connected external cooling mechanism, and more preferably the second operating position is generated by the absence of the aforementioned operating element. It is specified here that the corresponding straight-through valve of the exposed auxiliary joint of the removed cooling mechanism is in the second operating position. Thus, the basic cooling channel system is, in principle, sealed in the medium in the areas of all exposed auxiliary joints. At the connection point with the external cooling mechanism, the corresponding straight-through valve of the respective auxiliary joint is in the first operating position. Thus, the basic cooling channel system is, in principle, open for cooling medium flow in all areas of the connected auxiliary joints.

[0018] In a preferred embodiment of the cooling system, the straight-through valves of the additional connectors each have connection areas to allow for the detachable connection of the basic cooling channel system to the cooling section of an external cooling mechanism, wherein the respective connection areas are configured as complementary elements to the common medium connection of the external cooling mechanism, particularly as closed connections. Here, the first operating position can be located in the connection between the basic cooling module and the external cooling mechanism, and the second operating position can be located in the detached connection between the basic cooling module and the cooling mechanism. This advantageously ensures that scaling of the cooling system can be performed at any time by adding and / or removing one or more external cooling mechanisms without the need for cooling medium loss or refilling. Such closed connections are also known, for example, in garden long rubber hose systems. Spring-supported plug systems are often used here, for example. The open or closed positions of the complementary elements can be determined by elasticity, magnetism, or even electricity, particularly depending on the connection state of the complementary elements. Here, the corresponding force acts, for example, on at least one adjusting element that is part of the medium connection.

[0019] In one improved embodiment of the cooling system, the additional connectors each have a controllable or adjustable, particularly electrically controllable or adjustable, straight-through valve to regulate the volumetric flow rate of the cooling medium. This allows the heat dissipation capacity of the connected external cooling mechanism to be variably or precisely adjusted to the actual heat dissipation requirements. In this way, the electronic module containing the cooling device can operate within a defined operating temperature window. Overall, this results in a more energy-efficient and application-appropriate cooling system. Alternatively or supplementarily, for this purpose, the basic cooling channel system can have sections with different cross-sectional dimensions, such that the achieved volumetric flow rates of the cooling medium between at least two pairs of additional connectors are different from each other.

[0020] The present invention also relates to a single module element of a cooling system in at least one of the embodiments described above. The single module element preferably includes at least one complementary element of a common medium coupling of another single module element capable of being connected to the single module element, the other single module element having suitable other complementary elements of the common medium coupling.

[0021] The present invention also provides a cooling device comprising at least one cooling system according to at least one embodiment described above. Here, at least two auxiliary connectors are connected to a cooling section of an external cooling mechanism. Preferably, the cooling device is part of an electronic module having electronic units. The cooling device is connected to the cooling mechanism, at least indirectly and thermally, in at least a portion of the area to dissipate lost heat. If the connected auxiliary connectors each have the aforementioned through valves, these auxiliary connectors are positioned in a first operating position due to the connection, thereby enabling the flow of cooling medium between the basic cooling channel system and the connected cooling section. This also applies when the medium connection between the auxiliary connectors and the external cooling mechanism is in a connected state.

[0022] The electronic module that preferably includes a cooling mechanism is, for example, a control device for a power module, particularly for motor vehicles. Furthermore, it is preferred that the cooling device is part of the vehicle's computer, particularly including a bus system, through which the electronic module, preferably in the form of a control device, is integrated into the overall system.

[0030] Figure 3c A schematic diagram of a straight-through valve including an electric coil is shown. Detailed Implementation

[0031] In the accompanying drawings, structural elements with the same function are represented by the same reference numerals.

[0032] Figure 1 A perspective view shows a device 300 having a cooling system 200 and at least one electronic module 100 detached from but capable of being connected to the cooling system 200.

[0033] The electronic module 100 has a housing 110 in which electronic units are housed in a closed configuration. The electronic module 100 additionally has a cooling mechanism 140, to which at least a portion of the electronic units is thermally connected to dissipate heat loss. Here, the cooling mechanism 140 is permeated by a cooling medium 310, such as a cooling gas or coolant, which absorbs heat loss from the electronic units. For this purpose, the electronic module 100 has a module inlet and module outlet 141, 142 for the cooling medium 310. A cooling section 145 of the cooling mechanism 140 is constructed between the module inlet and the module outlet 141, 142, through which the cooling medium 310 is guided. When at least one electronic module 100 is connected to the cooling system 200, a cooling device 300' is constructed, through which the connected electronic module 100 can be cooled by means of the cooling system 200. Here, the cooling medium 310 and the maintenance of the cooling medium flow through the cooling system 200 are provided within a generally enclosed cooling channel system 320. For this purpose, the cooling system 200 is constructed as a basic cooling module 200' having a basic cooling channel system 220 and thus provides a distribution base for the cooling medium 310, which is connected to one or more external cooling mechanisms 140, particularly as part of the electronic module 100, as shown in this embodiment. The basic cooling channel system 220 here includes at least one cooling channel conduit 225 arranged between the main inlet and main outlet 211, 212 for the cooling medium 310. The generally enclosed cooling channel system 320 is thus composed of the basic cooling channel system 220 of the basic cooling module 200' and cooling sections 145 of each of the external cooling mechanisms, particularly the cooling mechanisms 140 of the electronic module 100, connected to the basic cooling channel system 220. Therefore, the basic cooling channel system 220 can be expanded by the cooling sections 145 connected to each of the external cooling mechanisms 140. For connection purposes, the basic cooling channel system 220 has at least two additional connectors 241, 242. These additional connectors each have a direct inlet leading to at least one cooling channel conduit 225. The main inlets and main outlets 211, 212 are at least indirectly connected to a media pump 280, through which a media flow is maintained, for example, within a closed cooling circuit 380, through the basic cooling channel system 220 and the connected cooling section 145. Furthermore, the media pump 280 is connected, for example, to a control or regulation system 350 to regulate the pump speed. For example, a plug connector 120 of at least one electronic module 100 is also connected to the control or regulation system 350.The connection between the control or regulation system 350 and the medium pump 280 and / or at least one electronic module 100 is preferably made by means of a bus system 355.

[0034] exist Figure 2a The basic cooling module 200' is shown in cross-sectional view AA. This cross-section is formed precisely through the channel orientation of the basic cooling channel system 220. The basic cooling channel system 220 can be designed very differently for specific applications. In a simple embodiment, the basic cooling channel system 220 is formed by two separate cooling channel pipes 225, wherein the main inlet and main outlet 211, 212 are preferably arranged in the end regions of the separate cooling channel pipes 225. The main inlet and main outlet 211, 212 can then be arranged on the same side of the basic cooling module 200' or on opposite sides of the basic cooling module 200' (not shown). In another simple embodiment, at least one continuous cooling channel pipe 225 is constructed in a U-shape as the basic cooling channel system 220 inside the basic cooling module 200' (shown in dashed lines). Here, the main inlet and main outlet 211, 212 are arranged on the same side of the basic cooling module 200' in the end regions of the continuous cooling channel pipe 225.

[0035] Generally, in all feasible embodiments, the at least one pair of additional connectors 241, 242 are associated with exactly one or at least one continuous cooling channel pipe 225. In this way, the cooling sections 145 of the external cooling mechanism 140 can be connected as separate parallel additional pipes. Alternatively or supplementary, the at least one pair of additional connectors 241, 242 can be associated with exactly two or at least two separate cooling channel pipes 225, whereby these additional connectors 241, 242 can be connected to each other across the cooling sections 145 of the external cooling mechanism 140.

[0036] Additional connectors 241 and 242 here respectively include or represent a straight-through valve 250 for the cooling medium 310. Here, the straight-through valve 250 is used to open the basic cooling channel system 220 for cooling medium flow in a first operating position I and to seal the basic cooling channel system 220 in a second operating position II. In principle, such a straight-through valve 250 can be manufactured in different structural forms. Figures 3a-3cThe preferred solution principle is schematically illustrated. What all solutions have in common is that the straight-through valve 250 has at least one regulating element 254, which can occupy different spatial positions by means of an actuating force FB. Here, at least in the first actuating position I, it occupies a spatial position inside the straight-through valve 250, for which the opening 251 inside the corresponding auxiliary joints 241, 242 continues to exist to allow the volumetric flow rate of the cooling medium 310. In the second actuating position II, the opening is locked by the regulating element 254, that is, completely sealed off by the medium. Figure 3a The diagram illustrates a schematic example of the principle, where the first and second operating positions I and II are determined by the spring force FF of spring 252a. If only the spring force FF acts as an operating force FB on the movable adjusting element 254 in the initial position, then, for example, the second operating position II occurs. However, if another, larger operating force FB overcomes the spring force FF and acts on the adjusting element 254, then the adjusting element moves to the first operating position I. This reaction force relative to the spring force FF is generated, for example, through the connection area of ​​the external cooling mechanism 140 in the function of the operating element, which acts externally on the adjusting element 254 via an engagement movement W when connected to the auxiliary connectors 241, 242. Figure 3b A similar implementation is shown, in which a magnet 252b is used instead of a spring 252a. Here, the initial position is induced solely by the action of the magnetic force FM on the adjusting element 254. The reaction force can then interact with... Figure 3a Similarly, the adjustment element 254 is then positioned to another operating position via the connecting element of the external cooling mechanism 140. Figure 3c Another embodiment is shown, in which the positioning of the regulating element 254 in the two operating devices I, II is obtained by electrical power FE as the operating force FB. This electrical power FE is generated here by an electric coil 152c arranged in the straight-through valve 250, which obtains a force component FE pointing towards the regulating element 254 according to the current. Here, the switching conditions for the electric coil 252c are generated, for example by electrical contact, in conjunction with the connection area of ​​the external cooling mechanism 140, so as to obtain the release for the operating position I. Generally, the operating positions I, II can also be achieved by just twisting, as previously described.

[0037] Therefore, in principle, the operating positions are preferably generated based on the connection state of the cooling system 200 with the external cooling mechanism 140, which is in particular part of the electronic module 100. At least one of the operating positions I and II is generated in particular by an operating element that is part of the connected external cooling mechanism 140, and it is further preferred that another operating position I or II is generated by the absence of the function of the aforementioned operating element. In summary, it is thus preferred to construct a common medium connection 360, especially as a closed connection. Here, the connection areas of the additional connectors 241, 242 and the corresponding connection areas of the external cooling mechanism 140 respectively form complementary elements 361, 362 of the medium connection 360, wherein the first operating position I is occupied in the connected portion and the second operating position II is occupied in the disconnected portion. Here, the module inlet and module outlet 141, 142 of the external cooling mechanism 140 can respectively have a straight-through valve 150 and / or a self-adjusting element 154 that can be arranged in multiple spatial positions, in a manner similar to that of the additional connectors 241, 242.

[0038] The described implementation may include, together with, the ability to additionally control or adjust at least one of the aforementioned regulating elements 154, 254 in its spatial positioning to define, and particularly on demand, the volumetric flow rate of the cooling medium 310 for the connected cooling mechanism 140, particularly as part of the electronic module 100. For example, the previously mentioned coil 152c may be used for this purpose. In principle, the coil may also have different regulating elements than those shown. For this purpose, the connected electronic module 100 may have, for example, a control or regulating electronic device. This control or regulating electronic device may also include a temperature sensor, for example, arranged on a circuit board in a region where the temperature is determined. Here, the control or regulating electronic device generates a control or regulating amount based on the acquired temperature value, by which the position of the regulating elements 154, 254 between operating positions I and II can be adjusted, particularly for operating the electronic module 100 within a defined operating temperature range. Alternatively, the corresponding electronic module 100 can be connected to a control or regulation system 350 located on the electronic module 100 via an external connector or plug connector 120. This control or regulation system is responsible for controlling or regulating the regulating elements 154 and 254, or for generating the control or regulation values. For this purpose, the electrically adjustable regulating element 254 of the basic cooling module 200' can also be connected to the control or regulation system 350 via a bus system 355.

[0039] The basic cooling module 200' is modularly constructed from at least two or more individual module elements 210.1, 210.2, 210.3, and 210.x to flexibly expand the basic cooling channel system 220. Each individual module element 210.1, 210.2, 210.3, and 210.x includes at least one partial section 225.a, 225.b, 225.c, and 225.x of the at least one cooling channel pipe 225. In the particularly detachable connection region V of two directly adjacent individual module elements 210.1, 210.2, 210.3, and 210.x, the at least one partial section 225.a, 225.b, 225.c, and 225.x therein are continuously connected to form at least one cooling channel pipe 225. In order for the individual modular elements 210.1, 210.2, 210.3, and 210.x to be mechanically held in the composite structure when constructing the basic cooling module 200', these individual modular elements are connected to each other by means of a force-transmitting connection system 270, which is particularly detachable, and / or a form-fit connection. For example, a threaded connection including at least one screw 271 is suitable as a feasible option, which passes through all the individual modular elements 210.1, 210.2, 210.3, and 210.x to be held through a fixing hole 215. The individual modular elements 210.1, 210.2, 210.3, and 210.x arranged therebetween are clamped and secured by means of a locking nut in the end region of the screw 271. Alternatively, the individual modular elements 210.1, 210.2, 210.3, and 210.x can also be secured in the connection area (not shown) by corresponding locking connections, plug-in connections, or clamp connections. Similarly, the electronic module 100 is additionally secured by at least one individual module element 210.1, 210.2, 210.3, 210.x. For this purpose, the electronic module 100 and the at least one individual module element 210.1, 210.2, 210.3, 210.x each have additional complementary elements 371, 372 of a common, particularly detachable, securing system 370, which are together functionally associated. The securing system 370 is, for example, a threaded connection, a locking connection, a plug-in connection, or a clamp connection.

[0040] In the corresponding connection region V, the directly adjacent segments 225.a, 225.b, 225.c, and 225.x are sealed relative to each other. In this way, loss of cooling medium in the composite structure of the individual module elements 210.1, 210.2, 210.3, and 210.x is prevented.

[0041] Figure 2bTwo individual module elements 210.1, 210.2, 210.3, and 210.x are shown in a detached perspective view. In principle, two directly adjacent individual module elements 210.1, 210.2, 210.3, and 210.x each have complementary elements 261 and 262 in the connection region V, specifically as closed-type connectors, sharing a common media connector 260.
