Description

The invention relates to a device for supplying power to a motor vehicle, in particular a car, truck or motorcycle. Such a device comprises one or more memory cell modules, each comprising one or more electrochemical storage cells and / or double-layer capacitors, which are arranged side by side and / or one above the other. The apparatus further includes a radiator block that includes a receptacle for the one or more memory cell modules and a structure for dissipating the heat emitted by the one or more memory cell modules. The radiator block further includes a force receiving device having at least one plate-shaped force receiving element with three pairs of boundary surfaces, wherein the force receiving element is adapted to receive a force acting on the device in the event of a crash and to derive around the memory cell modules. The invention further relates to a radiator block for such a device.

The memory cells and / or double-layer capacitors of a memory cell module are typically electrically connected in series and / or in parallel with one another in order to be able to provide sufficient energy for an electric motor, for example. A power supply device may include a plurality of such memory cell modules. In the event of an accident, it must be ensured that the memory cells and / or double-layer capacitors of the memory cell module are not damaged, since any leaking electrolyte could lead to damage to the environment and / or people. Furthermore, a pinch of the memory cells could lead to a short circuit in the cell. This can cause a thermal incident in the memory cell, which could lead to a degassing, to an explosion or to a fire of the memory cells.

Furthermore, the electrochemical storage cells and / or double-layer capacitors can reach considerable temperatures during operation, so that their cooling is necessary. The cooling of the electrochemical storage cells and / or double-layer capacitors takes place from the outside. If sufficient cooling can not be guaranteed with sufficient certainty, defects can quickly occur that are not economically compatible with the service life requirements when used in automobiles.

It is therefore an object of the present invention to provide a device for powering a motor vehicle and a radiator block, which have a high protection against damage to the memory cells and their mechanical fasteners, but at the same time with little effort and thus are inexpensive to produce.

This object is achieved by a device for power supply with the features of claim 1 and a radiator block with the features of claim 23. Advantageous embodiments will be apparent from the dependent claims.

The invention provides a device for powering a motor vehicle, in particular a car, truck or motorcycle, with one or more memory cell modules, each comprising one or more electrochemical storage cells and / or double-layer capacitors, which are arranged side by side and / or one above the other, and with a radiator block comprising a receptacle for the memory cell module (s) and a structure for dissipating the heat emitted by the one or more memory cell modules. Furthermore, the radiator block has a force receiving device with at least one plate-shaped force-receiving element with three pairs of boundary surfaces, wherein the force-receiving element is designed to absorb a force acting on the device in the event of a crash and to divert it around the memory cell modules. According to the invention, at least the two pairs of boundary surfaces with the smaller area contents along a respective boundary surface longitudinal direction are executed without elevation.

By providing the force receiving device with at least one plate-shaped force receiving element (crash plate), a protection of the memory cells and / or double-layer capacitors of a memory cell module is provided. In a deformation of a body component and a mechanical contact with the device according to the invention, the forces are first taken up by the force receiving device and passed around the memory cell modules around. This can prevent damage to the memory cell modules until a maximum force occurs.

The fact that at least two pairs of boundary surfaces are executed without elevation, the force receiving element without expensive tools and thus in a simple manner and therefore can be produced inexpensively. As a result, the manufacturing costs for the entire inventive device for power supply compared to known devices are lower.

Under a plate-shaped force receiving element is a force receiving element to understand which has the shape of a cuboid in which one edge length is substantially smaller than the other two edge lengths and thus a pair of boundary surfaces has a much larger surface area than the other two pairs of boundary surfaces.

In a plate-shaped force receiving element, the pairs of boundary surfaces with the smaller surface areas each have the shape of a rectangle, in which one side length is substantially larger than the other. These boundary surfaces thus have the shape of an elongated rectangle and thus have a boundary surface longitudinal direction. According to the invention, the force receiving element for at least the two pairs of boundary surfaces with the smaller surface contents along the respective Begrenzungsflächenlängsrichtungen no elevations. Ie. along any straight line lying in the boundary surface, which is aligned parallel to the longitudinal direction of the boundary surface, the boundary surface has no material overhangs. In this consideration, unevenness of the boundary surface, which is due to the surface properties of the material from which the force receiving element is made, or which arise during processing of the material, is disregarded.

According to the invention, at least four of the six boundary surfaces are carried out without elevation in the force receiving element.

Through the use of the plate-shaped force receiving element, a power line takes place around the memory cell modules.

In a further embodiment of the invention, all three pairs of boundary surfaces are executed without funding. Thus, all boundary surfaces of the force receiving element in a simple manner and therefore can be produced inexpensively. This measure contributes consistently to reducing the manufacturing cost of the device for power supply.

In a further embodiment of the invention, the boundary surfaces are flat or convex. In particular plan running boundary surfaces can be particularly simple and thus inexpensive to produce. Preferably, the pair of boundary surfaces with the largest surface area is made planar. The two pairs of boundary surfaces with the smaller surface contents can then all be flat or all convex. But it is also conceivable that of these two pairs of boundary surfaces, a pair of flat and a pair of convex is executed.

In a further embodiment of the invention, the force receiving element is designed as a hollow profile. This measure makes it possible to realize a particularly light but nevertheless with a sufficiently high rigidity possessing force receiving element. The hollow profile preferably has structural channels formed in the direction of the force to be absorbed, which ensures to a high degree that in the event of a crash, a force acting on the device is optimally absorbed and dissipated around the memory cell modules.

In a further embodiment of the invention, the force receiving element has a number of running inside the guide channels. By this measure, a space-optimized, yet to be described clamping device can be realized.

In a further embodiment, the at least one force-receiving element for the power line interacts with one or more component or components surrounding the radiator block. In order to improve the protective function, corresponding components are provided which, in the case of a deformation of a body component in the region of the device, project into the cooler block by the amount by which the at least one force absorption element is reset. As a result, the recording and forwarding of a force acting on the device in the event of a crash force is improved, thus ensuring compliance with the Kraftleitpfads.

In order to be able to provide the device according to the invention for the power supply of a motor vehicle stably, but nevertheless compactly, it is expedient for the at least one force absorption element to be guided laterally past one of the memory cell modules. Alternatively or additionally, the at least one force-receiving element can be arranged between two memory cell modules. Maximum protection for the memory cell modules is provided when at least one of the force-receiving elements is provided between each two adjacent memory cell modules.

In a further embodiment, at least two force-receiving elements, which are each assigned to different and adjacent receptacles, are arranged one behind the other in a force-conducting direction. The provision of two force-receiving elements arranged one behind the other can be provided, for example, when the device has two receptacles, arranged one after the other in a force effect and separated from each other, in which at least one memory cell module is introduced. Such a configuration is, for example, for reasons of handling during the production and for optimal heat dissipation advantageous. The power receiving elements may, if possible assembly technology, also be integrally formed.

If two force receiving elements, which are each assigned to different and adjacent receptacles, are arranged behind one another in a force-directing direction, it is furthermore expedient if the force-receiving elements arranged one behind the other are arranged adjacent to one another for the power line. As a result, the power transmission from that force receiving element, which is acted upon by a deforming body component with force, forwarded to the underlying force receiving element, without the respective recordings or memory cell modules are exposed to a harmful force.

Conveniently, the at least one force receiving element extends in the direction of a vehicle longitudinal axis or a vehicle transverse axis when the device is installed in the vehicle. As a result, the installation situation of the device in the motor vehicle and typical accident scenarios are taken into account. Among other things, the installation situation depends on where in the vehicle the device is installed and in which direction in the event of an accident deformation of the vehicle body is most likely.

A further stabilization of the device and an improvement of the heat dissipation is effected by providing the structure for heat removal at least on one side of the receptacle and the cooler block comprises a tensioning device which is designed to generate a predetermined force, by which the structure for Heat removal can be pressed to a respective memory cell module. This advantageous embodiment is based on the consideration that a minimum pressure between the components must be applied in order to avoid air bubbles with a high thermal resistance and to ensure good thermal contact. This minimum pressure can continue to prevent relative movements of the components to each other. The necessary minimum pressure is provided in a device for power supply by the tensioning device. The tensioning device generates the force necessary between the heat dissipation structure and a respective memory cell module to improve the thermal contact between the memory cell modules and the heat dissipation structure.

The tensioning device of the device comprises, in an expedient embodiment, a number of connecting means, which is designed to generate the predetermined force and to transmit it directly or indirectly to the structure for heat dissipation. As will be apparent from the following description, the connecting means may be a simple screw or similar fastening means. In principle, any type of connection means which can generate the predetermined force is suitable.

According to a further embodiment, the structure for heat dissipation comprises at least on the opposite sides of the receptacle each a cooling plate with cooling channels for a coolant or a refrigerant, which are fluidly connected at one end of the receptacle via flexible cooling channels. The flexible, z. B. arcuate, cooling channels same during installation a distance difference between the cooling plates after the application of force by giving way during the tension and z. B. bend or deflect.

According to a further embodiment, in each case a clamping plate is provided on the side facing away from the memory cell modules or the sides of the structure for heat dissipation, wherein the number of connecting means the clamping plates non-positively and / or positively connects with each other. By providing the clamping plates, in addition to the structure for heat dissipation, a structurally more stable cooler block is provided. In particular, the clamping plates are formed from a metal or a plastic. It is particularly preferred in this case if the clamping device, in particular the clamping plate, is formed from a thermally insulating material or comprises a thermally insulating material. For example, a thermally insulating layer may be applied to the existing metal clamping plate. As a result, the cooling efficiency of the power supply device can be improved.

It is expedient for assembly reasons, if the clamping plate before the application of force by the number of connecting means has a direction of the opposite direction of curvature. In this way, a good thermal contact in the middle of the longitudinal axis of a respective memory cell or of a respective memory cell module can be achieved. Typically, the deflection of the cooling plate or clamping plate is greatest in this area. To counteract such a deflection, the clamping plate, which serves for clamping, is pre-bent in the opposite direction. Due to the tension, the clamping plate is brought into a planar shape. The spring force now acts on the structure for heat dissipation and thus supports the generation of the desired force between the clamping plate and the respective memory cell modules.

In an alternative embodiment, the number of connecting means with the arranged on opposite sides of the receptacle cooling plates non-positively and / or positively connected to each other. In this embodiment, it is ensured that the cooling plates are dimensioned sufficiently to accommodate the forces applied by the connecting means can. This can be ensured, for example, by the material thickness of the cooling plates or local reinforcements in the area of the introduction of force. On the other hand, the structure of the device is improved by the stable cooling plates.

It is further provided that the number of connecting means are connected directly or indirectly via one or more support rails, which are formed of a rigid material, with the cooling plates or the clamping plates. By providing the support rails, the force need not be introduced directly into the cooling plates or the clamping plates. Rather, the forces are locally introduced into the support rails and distributed by these on a larger area. The support rails can be made for example of a metal or a suitably rigid plastic. They can also be integrated in the clamping plates. The support rails are also used to fix the at least one force receiving element (perpendicular to Kraftleitrichtung), for example by screwing.

In order to minimize the space required for the device according to the invention, it is further provided that at least some of the number of connecting means are passed through the receptacle. In particular, a respective connection means may be guided laterally past a memory cell module or between two memory modules. It is expedient if the force receiving element extends in the direction of the number of connecting means. In particular, it is advantageous if the connecting means and the force receiving element are arranged spatially to each other in order to get along with the least possible space.

It is also expedient if, in a memory cell module having a plurality of memory cells and / or double-layer capacitors, these are connected via thermally conductive and mechanically rigid profiles, wherein the clamping device presses the structure for heat removal onto the profiles. The profiles can be formed, for example, as extruded aluminum profiles. In the event of a crash, the profiles derive a force acting on the device around the memory cells or from the memory cells. In addition to the force receiving elements, the profiles thus ensure protection of the memory cells from damage. The further purpose of the profiles is to conduct the heat from the storage cells to the structure for heat removal. Due to the shape of the profiles, it is possible to dissipate heat over a large area of the memory cells.

In order to fix the device to the vehicle, the tensioning device may, according to a further advantageous embodiment, have a fixed bearing (eg in the form of an eyelet) at least on one side of the receptacle. Advantageously located on the other side of the receptacle at least one floating bearing. The one-sided fixation of the device ensures that the clamping plates can be set over the lifetime, whereby the cooling and clamping plates always remain in thermal contact with the modules. On the other hand, the one-sided storage offers advantages in the event of a crash, since a force is introduced only on one side into the device, while the other side remains free to a certain extent freely. The fixed bearing and / or the sliding bearing can optionally be formed on one of the clamping plates and / or the retaining rails. Appropriately, are on a side wall of the device all the bearings, while on the opposite side wall of the device, the sliding bearings are provided. Alternatively, can be provided on both sides of the recording fixed bearing.

A particularly simple handling and assembly of the device according to the invention results when the radiator block is self-supporting. In this way it is possible to obtain different components of the device from different manufacturers and to combine them at a later time. In particular, the radiator block can be provided as a separate component. The memory cell modules can then contact the manufacturer of the device, e.g. B. at the manufacturer of the vehicle or the memory modules, introduced into the radiator block and braced with this.

The invention also provides a radiator block for a device for powering a motor vehicle, in particular a car, truck or motorcycle, wherein the device for power supply comprises one or more memory cell modules, each comprising one or more electrochemical storage cells and / or double-layer capacitors, the side and / or are arranged one above the other. The radiator block includes a receptacle for the one or more memory cell modules and a structure for dissipating the heat emitted by the one or more memory cell modules. Furthermore, the radiator block has a force receiving device with at least one plate-shaped force receiving element with three pairs of boundary surfaces, wherein the force receiving element is adapted to, in the event of a crash on the Device acting force and divert around the memory cell modules around. According to the invention, at least the two pairs of boundary surfaces with the smaller area contents along a respective boundary surface longitudinal direction are executed without elevation.

The radiator block according to the invention, which essentially represents a combination of structure for heat removal and clamping device, has the same advantages as have been described in connection with the device according to the invention.

The invention will be described in more detail below with reference to exemplary embodiments in the drawings. Show it:

1 shows a cross-sectional view of a schematic, cooler block according to the invention 20 , The radiator block 20 includes a respective recording 21 for example, two memory cell modules arranged next to one another 10 , Each of the memory cell modules 10 comprises a number of electrochemical storage cells 12 and / or double-layer capacitors, which are arranged by way of example in two rows next to each other. Each row includes, by way of example only, six memory cells 12 one above the other. For mechanical fixation of the memory cells 12 as well as to improve heat dissipation are the memory cells 12 with thermally conductive profiles 13 coupled. The profiles 13 are for example extruded aluminum profiles. The cross-sectional shape of a particular profile 13 is due to the shape of the memory cells 12 adapted, each with two adjacent memory cells 12 in a profile 13 to lie down. The result wing-shaped profiles 13 are designed to be flat on the side, so that these with a coolant or refrigerant leading structure 22 of the radiator block 20 brought into large-area contact.

The coolant or refrigerant leading structure 22 includes on opposite sides of a respective receptacle 21 one cooling plate each 24 on which of the memory cell modules 10 facing away from a number of cooling channels 23 extends. The cooling plates are preferably made of aluminum. The cooling channels 23 For example, they can be designed as multiport tubes (so-called flat tubes). The cooling channels 23 extend parallel to a longitudinal axis of a respective memory cell in the leaf level. To the between the two memory cell modules 10 To be able to remove any heat that accumulates twice is optional between the two, a respective memory cell module 10 associated cooling plates 24 twice the number of cooling channels 23 intended. This also results from the fact that on the opposite sides of each recording 21 arranged cooling channels over on the front side of the recording 21 arcuate cooling channel sections (see. 3 ) are fluidically connected with each other.

On the outside of the coolant or refrigerant leading structure 22 is each a clamping plate 31 provided, which have a in 1 not shown number of connecting means are interconnected. Through the clamping plates 31 a force is generated by which the coolant or refrigerant leading structure 22 ie the cooling plates 24 to a respective memory cell module 10 be pressed. The clamping plates 31 as well as the connecting means not shown are part a tensioning device 30 , which together with the coolant or refrigerant leading structure 22 the radiator block 20 formed. The connecting means connect the clamping plates 31 positive and / or positive fit with each other. The clamping plates 31 are preferably formed of a metal or a plastic. In particular, the clamping plates 31 made of a material which is thermally insulating, in order to dissipate the heat generated in the storage cells by the coolant or refrigerant-carrying structure 22 to enable or support. Used as material for the clamping plates 31 Used metal, so this is to provide the thermal insulation can be provided with an insulating coating.

As seen from the sectional view of 1 It is obvious that the clamping plates are 31 under the respective memory cell modules 10 pulled around. The clamping plates 31 form in this lower floor area a conclusion of the radiator block 20 out. By the shape of the clamping plates 31 In addition, the inherent stability of the radiator block 20 improved. It is preferred if the radiator block 20 has a self-supporting structure, since then the handling and manufacture of a device for power supply according to the invention is possible in a particularly simple manner. It is therefore also appropriate if the clamping plates 31 on theirs from the memory cell modules 10 opposite side surfaces are provided with a profiling, which z. B. - as in 1 shown - can serve to accommodate the cooling channels and improved stability and rigidity of the clamping plates 31 and thus the radiator block 20 allows.

Through the clamping device 30 in the form of the clamping plates 31 as well as connecting these connecting means thus a force is generated by the coolant or refrigerant leading structure 22 to a respective memory cell module 10 be pressed. More precisely, the cooling plates 24 to the heat-conducting profiles 13 the memory cell modules 10 pressed. Due to the applied minimum pressure between the components, air pockets, which have a high thermal resistance, can be avoided. As a result, a good thermal contact between the heat-dissipating profiles 13 and the coolant or refrigerant leading structure 22 manufactured, allowing a good cooling of the memory cells 12 is guaranteed. By the pressure of the clamping device further relative movements of the components are prevented from each other, since due to the applied force is given a frictional engagement.

Unless the clamping plates 31 are made of a sheet steel and the cooling plates 24 Made of aluminum, to prevent corrosion is a corrosion-inhibiting layer between the clamping plates 31 and the coolant or refrigerant leading structure 22 intended. The corrosion-inhibiting layer can be applied, for example, to the clamping plates 31 be upset. On the provision of such a corrosion-inhibiting layer can be omitted if the clamping plates z. B. made of stainless steel or plastic.

To a good thermal contact in the direction of extension of the memory cells 12 (ie in the leaf level), the deflection of the radiator block must 20 and in particular the clamping plates 31 be taken into account. To counteract such a deflection, the clamping plates 31 bent in the opposite direction of the later direction of force. This is schematically in 11a illustrated in a plan view, wherein the radiator block in the embodiment for receiving a single memory cell module 10 is trained. 11a It can be seen here without further ado that the clamping plates 31 without force applied by the connecting means in the region of the ends of a respective memory cell 12 spaced from the associated cooling plate 24 are formed. By the tension of the clamping plates 31 by means of the connecting means 33 The clamping plates are bent straight and a spring force of the clamping plates acts in addition to the cooling plates of the radiator block 20 , This is schematically in 11b from which it is further evident that the connecting elements 33 laterally on the memory cell module 10 are passed. This in 11b illustrated design variant is preferred on the one hand for space minimization reasons and on the other hand for thermal reasons.

A lanyard 33 For example, includes a screw which engages in a cylindrically shaped nut with an internal thread. The mother acts on the clamping plate 31 on one side of the picture 21 or the memory cell module 10 and the screw the clamping plate 31 on the opposite side of the picture 21 or memory cell module 10 with power. The cylinder portion of the nut is preferably formed such that the screw does not protrude beyond a rear end of the nut at the predetermined force generated by them. As a result, a sufficiently large actuating travel for the screw is available, without it protruding beyond a side surface of the device for generating voltage. By sufficient dimensioning of the length of the nut beyond a pre-assembly can be carried out according to the screw and the nut are already connected to each other before the memory cell modules are introduced into the respective receptacle of the radiator block. To generate the predetermined force, the screws need only be screwed further into the nuts.

In principle, differently configured connecting means in a device according to the invention for voltage supply are conceivable as long as it is ensured that the predetermined force is applied to the coolant or refrigerant-carrying structure. In particular, the connecting means could also be formed by a crimped spring steel spoke.

2 shows a partial cross-sectional view of a device according to the invention 1 to the power supply. In this illustration, only the right is in 1 shown memory cell module 10 in his recording 21 of the radiator block 20 shown. Also visible is the radiator block 20 surrounding housing. This is from a first housing part 25 , a housing pan, and a second housing part 26 , a housing cover formed. The first and second housing part 25 . 26 For example, they can be made of a plastic or cast aluminum. The one with the memory cell modules 10 equipped radiator block 20 can, after the tension on the described clamping device was carried out and the production of all electrical connections of the memory cell modules was made in the first housing part 25 introduced and with the second housing part 26 be closed. In 2 is also a retaining rail 32 the tensioning device 30 seen. Along a respective side surface of the radiator block 20 is a plurality of such retaining rails 32 intended. The support rails formed from a rigid material 32 serve to the connecting means 33 indirectly with the clamping plates 31 connect to. The force applied by the connecting elements thus does not act directly on the clamping plates 31 but on the support rails 32 , whereby the force is distributed over the surface of the retaining rails and on the clamping plates 31 is transmitted.

From the described functionality of the support rails 32 Thus, it already results that these are arranged in the region between longitudinally adjacent memory cell modules.

This is better from the perspective view of a radiator block according to the invention 20 in 3 seen. The radiator block 20 includes eight shots as an example 21 for a respective memory cell module, of which in 3 an example with the reference numeral 21 is marked. Four shots 21 are arranged in two rows next to each other in the longitudinal direction. According to the drawn coordinate system corresponds to the longitudinal direction of the radiator block 20 a vehicle transverse axis (y-axis of the coordinate system). From the perspective view, the along the clamping plates 31 distributed holding rails 32 clearly visible. Due to the perspective view are in 3 only those on the front long side of the radiator block 20 arranged holding rails 32 to see, arranged on the rear longitudinal side support rails are hidden. The retaining rails 32 are laterally or between two shots 21 arranged.

At the front sides of the radiator block 20 run the already mentioned above flexible and exemplary arcuate executed cooling channels 23 which are on the opposite sides of a recording 21 located and with the cooling plates 24 connected cooling channels 23 connect with each other. Due to the perspective view are in 3 only those on the rear long side of the radiator block 20 arranged cooling plates 24 and arranged at the left end side, arcuate cooling channels 23 to see. On the front longitudinal side are also cooling plates and on the right front side arcuate cooling channels are also arranged. The arcuate course of the cooling channels 23 on the front sides of a respective recording 21 allows a certain flexibility of the cooling channels 23 in the application of force to the coolant or refrigerant leading structure 22 through the tensioning device 30 , Due to the curved course of the cooling channels 23 the recordings 21 For example, the reliability after assembly of the device can be improved.

In the x direction of the in 3 drawn coordinate system (ie in the vehicle longitudinal axis) are between two support rails 32 two, hereinafter referred to as crash plates force receiving elements 40 arranged. The crash plates 40 limit along with the coolant or refrigerant leading structure 22 one recording each 21 for a memory cell module 10 , The arrangement of the crash plates 40 goes more clearly from the 4 to 6 out.

In 4 is a plate-shaped force receiving element 40 shown having three pairs of boundary surfaces, wherein belonging to a first pair of boundary surfaces with the reference numerals 51a and 51b and the boundary surfaces belonging to a second pair with the reference numerals 52a and 52b and the boundary surfaces belonging to a third pair with the reference numerals 53a and 53b Marked are. The force receiving element 40 has the shape of a cuboid and has three edge lengths, one of which is the first edge length 54 is much smaller than the second edge length 55 or the third edge length 56 , In other words: both the first surface area 57 the first boundary surfaces 51a . 51b , as well as the second surface area 58 the second boundary surfaces 52a . 52b is each considerably smaller than the third area 59 the third boundary surfaces 53a . 53b , As the illustration in 4 it can be seen, all have three pairs of boundary surfaces 51 . 52 . 53 each one boundary surface longitudinal direction, the first boundary surfaces 51a . 51b a first boundary surface longitudinal direction 60 , the second boundary surfaces 52a . 52b a second boundary surface longitudinal direction 61 and the third boundary surfaces 53a . 53b a third boundary surface longitudinal direction 62 , As the illustration in 4 it can be seen further, the two pairs of boundary surfaces 51 . 52 with the smaller area contents executed so that the boundary surfaces 51a . 51b . 52a . 52b along the respective boundary surface longitudinal direction 60 . 61 are redundant. Ie. along the respective boundary surface longitudinal direction, these boundary surfaces have no material overhangs, apart from minor material unevenness, which result from the surface properties of the material used and / or the processing method used.

As shown in 4 are in a similar way, the third boundary surfaces 53a . 53b executed without mercy. In the 4 shown representation of the plate-shaped force receiving element 40 should have no limiting effect. For example, it is also conceivable that leidglich the two pairs of boundary surfaces with the smaller surface contents are carried out according to donations.

As the illustration in 4 it can be seen, are the first boundary surfaces 51a . 51b and the second boundary surface 52b plan and the second boundary surface 52a Convex executed. Again, this is not intended to be limiting. Preferably, these four boundary surfaces can all be made plan. Likewise, in addition to the boundary surface 52a at least one further of the aforementioned boundary surfaces be convex.

As the illustration in 4 it can be seen further, is the force receiving element 40 designed as a hollow profile, which is why it has a number of structural channels in its interior 63 which are preferably formed in the direction of a force to be absorbed by the force receiving element F. In addition to the structural channels 63 has the force receiving element 40 in its interior also a number of guide channels 64 on. Through these guide channels 64 The connecting means can be passed, which together with the clamping plates 31 the tensioning device 30 form. The hollow profile can be produced for example by a drawing process. But it is also conceivable, the structural channels 63 and the guide channels 64 to work into a previously massive plate, for example by drilling or milling or by means of an etching process.

Overall, the force receiving element 40 (Crash plate) adapted to a device in a crash, more specifically in the event of a vehicle crash 1 to absorb power acting on the power supply and arranged in the device memory cell modules 10 derive around or around the individual memory cells 12 a respective memory cell module 10 to guide around. Such as the perspective views of 5 and 6 can be removed, are two power receiving elements 40 , the different and adjacent shots 21 are assigned, arranged one behind the other, preferably in a force direction. Here are the two power receiving elements 40 not directly, but over at least one cooling plate 24 in contact with each other. This ensures that forces occurring in the event of a crash completely through the device 1 be passed through.

6 shows a perspective and sectional view of a device according to the invention 1 to the power supply. The arrangement and the configuration of the crash plates which are arranged one after the other in the x (vehicle longitudinal direction) or y (vehicle transverse axis direction) direction are shown in the sectioned illustration 40 clearly visible. Here is the arrangement of the crash plates 40 relative to the coolant or refrigerant leading structure 22 or the cooling plates 24 , the clamping plate 31 and the retaining rail 32 and the crash plates 40 good to each other. Instead of the guide channels 64 can the crash plates 40 one each (in 6 not shown) groove 43 which extend in the x-direction over the entire width of the radiator block 20 or the device 1 extends. These grooves 43 serve for guiding and receiving the connecting means 33 (in 6 not shown), whereby also a space minimization in the y-direction of the radiator block 20 is achieved.

The clamping device also allows a simplified mounting of the device in a vehicle. The assembly takes place on the retaining rails 32 , which are on opposite sides of the radiator block 20 are arranged. For this purpose, at least have those on a side surface of the radiator block 20 disposed retaining rails 32 one fixed camp each 34 on, which by one from the retaining rail 32 bent portion is formed with an eyelet. This goes, for example, more clearly from the 7 . 8th and 9 out. On the eyelets, the support rails and thus the radiator block 20 bolted to a bodywork component of the vehicle. At the opposite support rails 32 can each have an open or floating bearing 35 provided, which allows a sliding movement in the x direction. In the y-direction and z-direction, however, a movement is prevented. Alternatively, the opposite retaining rails 32 one fixed camp each 34 exhibit. As shown in 10 can the floating bearing 35 through the interaction of a groove 36 in the retaining rail 32 a sheet 39 be formed of the body part of the vehicle. This is in the perspective view of 10 shown.

The tensioning device 30 also allows the inclusion of at least one electronic component 50 , For example, an electronic control of the device 1 to the power supply. It may be provided that the electronic component on or on the first or second housing part 25 . 26 is arranged, like this 9 can be seen. Alternatively or additionally, electronic components can also be used on the respective memory cell modules 10 be provided.

From the enlarged view of 7 The basic structure of the radiator block is again clear. In addition, this is the fixed camp 34 forming sheet metal section with the eyelet to recognize well.

In 8th are next to the rectangular recesses 37a . 37b . 37c . 37d also round recesses 38 intended. Through the round recesses 38 become the lanyards 33 guided to generate the predetermined force, with the coolant or refrigerant leading structure 22 to a respective memory cell module 10 is pressed. In 7 it can be seen that the round recesses 38 at the height of the guide channels 64 the crash plates 40 are located to guide the connecting means in a respective guide channel 64 to enable.

The inventive cooler block described 20 preferably has a self-supporting structure, whereby the handling and assembly is facilitated. For this purpose, the radiator block is provided with initially expanded clamping plates. The already completed memory cell modules 10 , which in particular the profiles described above 13 include, in respective receptacles of the radiator block 20 brought in. Then the tension is made. The thus prepared device can then be introduced into the two housing parts.

In the embodiments described above, the tensioning device has been described in connection with the structure leading to the coolant or refrigerant separate clamping plates. If the cooling plates of the coolant or refrigerant-carrying structure are sufficiently stable, the tension can possibly also be made via the cooling plates themselves. For this purpose, the described retaining rails are expediently used for power distribution, which are directly in contact with the cooling plates and press them to the respective memory cell modules. If the cooling plates have sufficient rigidity, the support rails can be omitted.

The advantage of the procedure according to the invention consists in good thermal contact of all components present in the heat conduction path (memory cell profile cooling plate cooling channels). In this case, the thermal contact can be maintained over the entire life of the device. The realization is possible in a simple and cost-effective manner. In particular, the tension also ensures stabilization of the coolant or refrigerant-carrying structure after its tension. By providing the crash plates, a protection of the memory cells against penetrating parts in the event of a crash is given.
