The first walls and the second walls are, for example, respective side walls, the first direction coinciding, for example, in the installation position of the storage device with the vehicle transverse direction and the second direction with the vehicle longitudinal direction. In this case, the storage device assumes its installation position in a completely manufactured state of the motor vehicle equipped with the storage device. In a direction perpendicular to the first direction and perpendicular to the second direction extending third direction of the receiving space is bounded by a bottom formed as a third wall of the housing, wherein, for example, in the installed position, the third direction coincides with the vehicle vertical direction, pointing in the vehicle vertical direction down.

In addition, the reveals WO 2004/053416 A1 a heat exchanger which comprises a particular surface base body made of thermoplastic material and a thermoplastic film applied to the base body as well as inlet connection and outlet connection for the supply and removal of a heat transfer medium.

Object of the present invention is to develop a housing, a memory device, a method and a motor vehicle of the type mentioned in such a way that a particularly advantageous temperature control of the memory device can be realized.

This object is achieved by a housing with the features of claim 1, by a memory device with the features of claim 13, by a method having the features of claim 14 and by a motor vehicle having the features of claim 15. Advantageous embodiments with expedient developments of the invention are specified in the remaining claims.

A first aspect of the invention relates to a housing for a storage device of a motor vehicle designed for storing electrical energy or electric current, which may be designed, for example, as a motor vehicle, in particular as a passenger car. The motor vehicle is designed, for example, as an electric vehicle or as a hybrid vehicle and, in its completely manufactured state, has at least one electric machine by means of which the motor vehicle can be electrically driven. For this purpose, the electric machine is operated in a motor operation and thus as an electric motor. In order to operate the electric machine in the engine operation, the electric machine is supplied with electrical energy stored by means of or in the storage device. Therefore, the storage device is also referred to as a traction battery, wherein the electric machine is also referred to as a traction machine.

In order to be able to realize particularly high electrical powers for electrically driving the motor vehicle, the storage device is preferably designed as a high-voltage component, in particular as a high-voltage battery (HV battery), so that it memory device, for example, an electrical voltage, in particular an electrical operating voltage , having or provides, wherein the electrical voltage, in particular the electrical operating voltage is greater than 50 volts. Preferably, the electrical voltage, in particular the electrical operating voltage, several hundred volts, thereby being able to realize particularly high electrical power.

The housing has a receiving space for receiving at least one memory cell for storing the electrical energy. In other words, the memory device in its completely manufactured state, the housing and the at least one memory cell, which is at least partially, in particular at least predominantly or completely, arranged in the receiving space and thus in the housing in the fully manufactured state of the storage device. Preferably, the memory device comprises a plurality of memory cells which are each at least partially, in particular at least predominantly or completely, arranged in the receiving space and thus in the housing. For example, in order to be able to realize the aforementioned high electrical voltage, the memory cells are electrically connected to one another, for example. The memory device may be formed as a so-called memory module, which has a plurality of memory cells electrically connected to one another, which are arranged in the receiving space. Then, the housing is formed, for example, as a module housing. Furthermore, it is conceivable that the storage device is designed as an energy store, which has a plurality of electrically interconnected modules, which are designed as the aforementioned module. Then, for example, the modules and thus their respective memory cells in the housing then designed, for example, as a storage housing or in the receiving space are each at least partially, in particular at least predominantly or completely.

If the storage device is designed, for example, as a battery, the respective memory cell is designed as a battery cell. In particular, it is conceivable that the memory cell is designed as a lithium-ion cell, so that the memory device is formed for example as a lithium-ion battery.

The receiving space is bounded along a first direction on both sides, in particular completely, by first walls of the housing, wherein, for example, the first walls are spaced apart from one another along the first direction. Furthermore, the receiving space is bounded on both sides, in particular in each case completely, by second walls of the housing along a second direction running perpendicular to the first direction, wherein the second walls are spaced apart, for example, along the second direction. In a direction perpendicular to the first direction and perpendicular to the second direction extending third direction of the receiving space, for example, in particular completely, limited by a third wall of the housing. Thus, for example, the first direction and the second direction span a plane, the third direction being relative to the plane.

In the installed position of the storage device and thus of the housing, the first direction coincides, for example, with the vehicle longitudinal direction or with the vehicle transverse direction, so that then coincides in the installation position, the second direction with the vehicle transverse direction or with the vehicle longitudinal direction. In the installed position then, for example, the third direction coincides with the vehicle vertical direction and thereby runs down in the vehicle vertical direction. In this case, the storage device or the housing assumes its or its installation position in the completely manufactured state of the storage device and in the fully manufactured state of the motor vehicle.

In order to be able to realize a particularly advantageous temperature control of the memory device in a particularly cost-effective manner, it is provided according to the invention that at least one of the walls formed from a metallic material and the receiving space at least partially, in particular at least predominantly or completely, in particular in one with the respective Direction coincident spatial direction, directly delimiting wall element has. Under the feature that the receiving space is at least partially directly bounded by the wall element, it is to be understood that, for example, a fluid received in the receiving space, such as a gas or a liquid, can directly flow to the wall element or directly touch or contact it. Thus, for example, no additional further wall element is arranged between the receiving space and the wall element. The at least one wall furthermore has tempering passages, through which a temperature control medium, in particular a tempering fluid, flows, which are arranged at least on a side of the wall element facing away from the receiving space. In this case, the temperature control channels are at least partially limited by a plastic molded onto the wall element, in particular directly. The feature that the tempering passages through which the temperature control medium flows is at least partially delimited directly by the plastic means that the temperature control medium flowing through the temperature control passages flows directly around the plastic and thus directly contacts or contacts it. Under the feature that the plastic is molded onto the wall element, is to be understood that the plastic is provided by injection molding, that is by an injection molding process, with the plastic. In the context of the injection molding process, the initially liquid plastic is injected onto or against the wall element which has already been produced, for example, previously and in particular is inherently rigid, and in particular is connected to the wall element. The wall element can be at least partially encapsulated with the plastic.

As indicated above, the wall element per se is preferably inherently rigid and thus dimensionally stable. Furthermore, the plastic is also inherently rigid or dimensionally stable. In other words, the injection-molded plastic to the inherently rigid wall element at least or exactly one piece and the tempering at least partially limiting component, which is formed from the plastic and intrinsically stiff or dimensionally stable forms. This means that the component, also referred to as a plastic component, is not, for example, rigid or dimensionally unstable, for example, like a foil, but rather the plastic component retains its own shape and is therefore intrinsically rigid or dimensionally stable. As part of the injection molding of the initially liquid plastic is cured or curing of the initially liquid plastic is allowed, causing the initially liquid plastic to the plastic component.

Since the wall element formed from the metallic material at least partially and directly limits the receiving space, a particularly advantageous, effective and efficient heat exchange between at least one arranged in the receiving space or can be arranged component of the storage device and the wall element. The at least one component is arranged, for example, in the fully manufactured state of the storage device at least partially, in particular at least predominantly or completely, in the receiving space and touches the wall element directly or directly. The component may be the at least one memory cell but one of the aforementioned memory modules. If, for example, the wall element has a lower temperature than the component, an effective and efficient, and in particular direct, heat transfer from the component to the wall element can take place, so that in a short time a particularly large amount of heat is transferred from the component to the wall element and transported away from the component can be. As a result, for example, the device is cooled efficiently and effectively.

In contrast, if, for example, the wall element has a higher temperature than the component, then, for example, an efficient and effective as well as, in particular, direct heat transfer from the wall element to the component can take place. As a result, for example, the device can be heated effectively and efficiently. Overall, it can be seen that the wall element acts as a heat conducting element, by means of which the component, that is, for example, the at least one memory cell or the memory module, effectively, efficiently and demand-tempered, that is cooled and / or heated, can, in particular depending on the Temperature of the wall element.

Since the at least one wall also has the tempering passages through which the temperature control medium flows, a particularly advantageous and, in particular, efficient and effective heat exchange can take place between the wall element and the temperature control medium flowing through the temperature control passages.

As a result, the wall element can be tempered by means of the temperature control means, ie cooled and / or heated, so that an effective and efficient as well as active or targeted temperature control of the component can be realized via the wall element. In particular, the temperature control channels can act as cooling channels and the temperature control means as the coolant, in particular if the temperature control means has a lower temperature than the wall element. As a result, an efficient and effective, and preferably direct, heat transfer from the wall element to the temperature control medium flowing through the temperature control channels can take place, as a result of which the wall element is cooled. As a result, the device can be cooled effectively and efficiently via the wall element. If, for example, the tempering agent has a higher temperature than the wall element, an efficient and effective and, for example, direct heat transfer can take place from the temperature control medium flowing through the tempering passages to the wall element. As a result, the wall element is heated, so that for example via the wall element, the component can be heated by means of the temperature control. Then the temperature control channels act as heating channels, or the temperature control acts as a heating medium.

Preferably, a tempering fluid, in particular a tempering gas or preferably a tempering liquid, is used as the temperature control means, so that the component can be tempered effectively and efficiently by means of the wall element. This demand-based temperature control can be made particularly cost by means of the housing according to the invention, since the Housing can be produced inexpensively in itself. This is done in particular such that the wall element is provided by the aforementioned injection molding time and cost with the plastic and thereby connected to the plastic.

In order to keep the weight of the housing particularly low and to ensure a particularly advantageous heat exchange, it has been found to be advantageous if the metallic material is a light metal, in particular aluminum.

In a particularly advantageous embodiment of the invention, the plastic has a lower thermal conductivity than the metallic material. As a result, for example, a particularly advantageous heat exchange between the wall element and the component as well as between the wall element and the temperature control carried out, however, excessive heat exchange between the plastic and its environment can be avoided. As a result, for example, excessive heat loss from the receiving space on the plastic to the environment can be avoided or it can be avoided excessive heat input from the environment via the plastic in the temperature control, so that by means of the plastic, a cost-effective and particularly advantageous, especially thermal , Isolation or insulation of the housing can be realized. As a result, a highly efficient temperature control of the housing and thus of the component can be realized. In particular, the highest possible thermal conductivity of the component can be realized with the temperature control means, also referred to as tempering medium, in particular without additional further insulating components. Furthermore, the invention makes it possible to produce the housing with only a small number of components and assembly steps, and complex geometries of the cooling channels can be realized in a timely and cost-effective manner by the injection molding process. In addition, a secure separation of the receiving space can be ensured by the temperature control channels and thus by the temperature control, in particular over a long period or life. Thus, for example, an undesirable penetration of the temperature control can be avoided in the receiving space. This is particularly advantageous when the temperature control has at least one particularly inexpensive, but advantageous for temperature control component, in particular in the form of water.

The wall element is for example a prefabricated plate, which is already made before the plate with the plastic. The plate is at least partially over-injected with the plastic, for example, in the context of the injection molding process, whereby the plate can be integrated into the housing in a particularly simple and cost-effective manner. In addition, the fact that the tempering channels are at least partially limited by the plastic and thus formed, the temperature control channels are particularly simple and inexpensive integrated into the example designed as a battery housing housing. In addition, the invention enables the simple and cost-effective combination of, for example, coated and / or shaped and treated surfaces, in particular aluminum surfaces, in one component.

In particular, it can be seen that the temperature control channels are part of the at least one wall and thus integrated into the at least one wall. As a result, the aforementioned temperature of the device is integrated into the at least one wall, whereby the device can be effectively and efficiently tempered. The housing is designed as a hybrid component which comprises at least the wall element formed from the metallic material and the plastic which at least partially delimits the temperature control channels. Since the wall element is provided with the plastic by injection molding, the housing is designed in particular as an injection-molded hybrid component. The injection-molded hybrid component can be produced with only a small number of work steps and thus time and cost and without other components such as cooling lines, cooling plates, adhesives, foams, so that an efficient temperature can be displayed in a cost effective manner.

In a further embodiment of the invention, the temperature control channels are limited to the receiving space directly through the wall element. This is understood to mean that the temperature control medium flowing through the temperature control channels directly flows around the wall element and thus can touch or touch it. As a result, a particularly efficient, effective and direct heat exchange can take place between the temperature control medium flowing through the temperature control channels and the wall element. As a result, the component can be tempered in a simple manner particularly efficiently and as needed.

In a further embodiment of the invention, the temperature control channels along the first direction and / or along the second direction are directly bounded by the plastic, in particular completely. In this way, the temperature control can be easily and inexpensively manufactured.

In a further embodiment of the invention, at least a portion of a surface of the wall element with a surface structuring and / or at least one in addition to the Wall element and provided in addition to the plastic adhesion promoter, which is formed for example from a different material of the metallic material and the plastic material. In this case, the plastic is molded at least on the portion. In this way, a particularly firm connection of the plastic with the wall element can be ensured. As a result of the surface structuring, the wall element is roughened, for example, at least in the partial region, so that the surface structuring represents, for example, a roughening of the partial region or of the wall element. Due to the surface structuring, the wall element has a particularly large surface area, at least in the partial region, so that the wall element enters into an intimate and firm connection with the plastic.

In principle, it is conceivable that the wall element has at least one or more passage openings, which are formed as through-injection openings and are thus penetrated by the plastic. The plastic can thus engage or grasp, for example, respective wall regions of the wall element delimiting the through-flow openings, so that, for example, the wall element is positively connected to the plastic.

However, it has proven to be particularly advantageous if the wall element is free of passage openings penetrated by the plastic. In this way, a particularly good tightness can be realized, so that it can be avoided that the temperature control penetrates into the receiving space. If the wall element is free of injection openings, it is still possible to ensure a particularly firm connection between the plastic and the wall element, for example by using the adhesion promoter or the surface structuring.

A further embodiment is characterized in that at least one connection fluidically connected to the temperature control channels and through which the temperature control medium can flow is formed by the plastic through which the temperature control medium can be introduced into the temperature control channels and / or can be discharged from the temperature control channels. The plastic is thus at least a double function, since the plastic is used on the one hand for at least partially limiting the temperature control channels. On the other hand, the plastic is used to form the connection, via which the coolant can be introduced into the temperature control channels or removed from the temperature control channels. As a result, a functional integration is created so that the number of parts and thus the cost, weight and space requirements of the housing and thus the memory device can be kept very low overall.

In order to produce the housing in a particularly cost-effective manner, it is provided in a further embodiment of the invention that the tempering directly in a direction away from the receiving space and, for example, coincides with the first direction, with the second direction and with the third direction an outer wall member of the at least one wall are limited. Under the feature that the temperature control channels are partially and directly limited by the outer wall element, it is to be understood that the temperature control medium flowing through the temperature control channels directly flow or flow around the outer wall element and thus touch or touch.

It has been found to be particularly advantageous if the outer wall element is formed separately from the temperature control channels at least partially limiting plastic and connected to the plastic. Furthermore, the outer wall element is preferably formed separately from the wall element. The outer wall element is preferably inherently rigid or dimensionally stable and is connected, for example, in prefabricated or already manufactured state and after the injection of the plastic to the wall element with the temperature control channels at least partially limiting plastic. As a result, the housing can be made particularly simple and thus inexpensive.

Another embodiment is characterized in that the outer wall element is materially connected to the plastic. In this case, for example, the outer wall element is welded to the plastic, in particular without an additional material provided in addition to the plastic and in addition to the outer wall element. As a result, the number of parts and thus the weight and the cost of the housing can be kept very low. Alternatively or additionally, it can be provided that the outer wall element is adhesively bonded to the plastic, in particular by means of an adhesive or adhesive provided in addition to the outer wall element and in addition to the plastic. In this way, a particularly firm connection between the outer wall element and the temperature control channels at least partially limiting plastic can be ensured.

In a further, particularly advantageous embodiment of the invention, the outer wall element is formed from a metallic material. Alternatively, it is conceivable that the outer wall element is formed from a plastic. Of the Plastic, from which the outer wall element is formed, may be the same plastic as the Temperierkanäle at least partially limiting plastic. It is also preferably provided that the aforementioned plastic component and the outer wall element are formed as separately formed and interconnected components.

Another embodiment is characterized in that the at least one wall is one of the first walls, wherein the other first wall at least one integrally formed with the wall element of the at least one wall and thereby formed from the metallic material and the receiving space at least partially directly limiting further Wall element has. Thus, the wall elements, for example, side walls. This embodiment is thus based, for example, on a metallic base housing, which comprises the wall elements which are formed integrally with one another and produced from the metallic material and with which the temperature control channels are provided at least partially delimiting plastic.

It has been found to be particularly advantageous if the other first wall has at least on a side facing away from the receiving space of the other wall element and durchströmbare by the temperature control further Temperierkanäle that at least partially molded by the molded to the first wall element and the other wall element plastic, especially direct, limited. As a result, the receiving space and thus for example the component arranged at least partially in the receiving space can be tempered effectively both on the side of the first wall element and on the side of the further wall element, so that a particularly advantageous tempering can be realized.

The temperature control channels are, for example, fluidically connected to one another and thus form, for example, a fluidically coherent overall channel which, for example, can meander in at least one subregion.

Alternatively, it has been found to be particularly advantageous if the at least one wall is the third wall, wherein the plastic respective second wall elements of the first walls and / or the second walls are formed, wherein the respective second wall elements the receiving space along the first direction or Limit directly along the second direction. This embodiment is based, for example, on a base housing, which is formed from the temperature control channels at least partially delimiting and the second wall elements forming plastic, which is molded onto the formed, for example as a plate metallic wall element. This also makes the housing can be made particularly simple and inexpensive.

A second aspect of the invention relates to a storage device for storing electrical energy for a motor vehicle. The storage device comprises at least one housing which has a receiving space. The receiving space is along a first direction on both sides by first walls, along a direction perpendicular to the first direction second direction on both sides by second walls and in a direction perpendicular to the first direction and perpendicular to the second direction extending third direction by a bottom of the housing formed third wall of the Limited housing. In addition, the memory device comprises at least one memory cell accommodated in the receiving space for storing the electrical energy.

In order to be able to temper the memory device particularly advantageously in a particularly cost effective manner, it is provided according to the invention that at least one of the walls has at least one wall element formed of a metallic material and at least partially directly delimiting the receiving space and at least one side of the wall element facing away from the receiving space and by a tempering medium through-flow tempering channels, which are at least partially limited by a sprayed on the wall element plastic, in particular directly. Advantages and advantageous embodiments of the first aspect of the invention are to be regarded as advantages and advantageous embodiments of the second aspect of the invention, and vice versa.

A third aspect of the invention relates to a method for producing a housing, in particular a housing according to the invention, for a storage device of a motor vehicle designed to store electrical energy. In the method, a first direction along a first direction on both sides by first walls, along a direction perpendicular to the first direction second direction on both sides by second walls and in a direction perpendicular to the first direction and perpendicular to the second direction third direction by a trained as a bottom of the housing third Wall of the housing limited receiving space for receiving at least one memory cell for storing electrical energy produced.

Thus, the one-piece plastic component preferably limits both the temperature control channels 36a one wall 22 as well as the tempering channels 36b the other wall 22 and the tempering channel 36c or the temperature control channels 36c the Wall 32 ,

Plastic 38 preferably has a lower thermal conductivity than the metallic material, so that a particularly advantageous and cost-effective manner, a particularly advantageous thermal insulation can be created. To a particularly advantageous heat exchange between the temperature control and the wall elements 34a-c to be able to guarantee, are the tempering channels 36a-c each to the recording room 18 directly through the respective wall element 34a-c limited.

The temperature control channels 36a are, for example, in the third direction and in one of the third direction opposite and in 1 through an arrow 40 illustrated fourth direction in each case at least partially through the plastic 38 limited, in particular directly limited. In a coincident with the first direction and in 1 through an arrow 42 Illustrated fifth direction are, for example, the tempering channels 36a through a wall element 44 the Wall 22 , in particular directly limited, wherein the wall element 44 preferably in one piece with the wall element 34a formed and thus formed from the metallic material. The wall element 44 is for example a wall element of the wall 22 and take on the wall in the fifth direction 22 subsequent further recording room 46 the same function as the wall element 34b for the recording room 18 , In this case, for example, in the recording room 46 another component, in particular a further module, be recorded or arranged. The wall 22 thus acts, for example, as a central web between the recording rooms 18 and 46 , which are separated from each other, for example by the central web. The the tempering channel 36c limiting plastic 38 is for example part of the soil 30 and thus forms an insulating finish.

The floor 30 in this case has at least one port through which the temperature control medium can flow 48 on, which at least partially, in particular at least predominantly or completely, by the plastic 38 is formed. About the fluidic with the temperature control channels 36a-c connected connection 48 can the temperature control in the Temperierkanäle 36a-c introduced and / or from the temperature control channels 36a-c be dissipated. The connection 48 thus acts as an inlet and / or as a drain for the temperature control.

In particular, it is conceivable that the storage device 12 in their fully manufactured state, a plurality of separate housing formed 10 having. The separately formed housing 10 For example, they can be connected to one another in such a way, in particular fluidically, that the respective connections 48 be plugged together or put into each other. This will make the connections 48 and over the connections 48 the respective temperature control channels 36a-c the respective, separately formed housing 10 fluidly connected to each other, so that the separately formed housing 10 supplied in a particularly simple and cost-effective manner with the temperature control and can be flowed through by the temperature control. This allows a particularly advantageous temperature control of the storage device 12 be ensured in a simple and cost-effective manner.

Because the wall elements 34a-c are integrally formed with each other, a sufficient tightness of the housing 10 to the recording room 18 be ensured so that the temperature control is not in the receiving space 18 can penetrate. Furthermore, it can be seen that, for example, the wall elements 34a and 34b metallic side walls are, wherein the wall element 34c For example, a metallic floor element of the soil 30 is. The metallic side walls and the metallic bottom element form, for example, a metallic base housing, to which the plastic 38 is injected. Thus, the metallic base housing with the plastic 38 Mistake.

At least one respective subarea T of the respective wall element 34a-c is for example with an in 2 particularly schematically illustrated surface structuring O Mistake. Alternatively or additionally, at least the subarea T with at least one in addition to the respective wall element 34a-c and in addition to the plastic 38 provided and also referred to as a primer adhesion promoter P provided, the plastic 38 at least at the subarea T is injected. Through the surface structures O can be a particularly large surface of the respective wall element 34a-c be realized so that the plastic 38 firmly on the respective wall element 34a-c adheres. The surface structuring O is for example by lasers of the subarea T produced. In other words, for example, at least the subarea T subjected to a laser beam to produce the surface structuring O by means of the laser beam.

At the in 1 the first embodiment shown is the wall element 44 For example, an outer wall element through which the temperature control channels 36a in the reception room 18 pioneering fifth direction (arrow 42 ) is directly limited. The outer wall element is part of the in 1 left wall 22 or in one piece with the wall element 34a educated. Thus, the outer wall element is separate from the plastic 38 designed and connected to this at least indirectly, in particular directly. In this case, the outer wall element is inherently rigid and thus dimensionally stable. That the tempering channels 36a flowing temperature control can thus both the tempering channels 36a partly directly delimiting plastic 38 as well as the temperature control channels 36a partially delimiting wall element 34a and that the tempering channels 36a partially directly limiting outer wall element directly on or flow around and thus touch directly. As a result, for example, a special Advantageous heat transfer from the receiving space 18 or 46 take place at the temperature control.

The temperature control channels 36b For example, in a direction away from the receiving space and the fifth direction opposite sixth direction by an outer wall element 52 the in 1 right wall 22 directly bounded, with the sixth direction in 1 through an arrow 50 is illustrated and coincides with the first direction. The outer wall element 52 is separate from the temperature control channels 36b partially delimiting plastic 38 trained and with the tempering channels 36a-c limiting plastic 38 connected, wherein the outer wall element 52 intrinsically stiff or dimensionally stable is formed. In the first embodiment, the outer wall member is 52 made of a plastic, which is the same plastic as the plastic 38 can be.

As part of the molding of the plastic 38 against the respective wall element 34a-c Thus, for example, respective ribs 54 from the plastic 38 made, with the ribs 54 for example, the temperature control channels 36a , b in this case limit in the third direction and in the fourth direction. The temperature control channels 36 partially limiting ribs 54 For example, they are injected into a gap, which along the first direction on the one hand by the wall element 34a and on the other hand by the wall element 44 is limited. After, for example, the ribs 54 to the wall element 34b this is sprayed separately from the ribs 54 produced outer wall element 52 with the ribs 54 forming plastic or with the ribs 54 connected. For example, the respective outer wall element is firmly bonded to the plastic 38 connected, in particular with the plastic 38 welded and / or glued.

2 shows a second embodiment of the housing 10 , Like the first embodiment, the second embodiment is also based on the above-described metallic base housing which is in contact with the plastic 38 is provided when the plastic 38 is molded onto the metallic base housing. Also in the second embodiment is the through the plastic 38 at least predominantly, in particular completely, formed connection 48 in the ground 30 integrated.

In the second embodiment, the tempering channels 36c of the soil 30 in the direction of the arrow 28 illustrated third direction directly through an outer wall element 56 the Wall 32 and thus of the soil 30 limited, wherein the outer wall element 56 separately from the plastic 38 and thus separate from the ribs 54 trained and with the plastic 38 or with the ribs 54 connected is. For example, the aforementioned one-piece plastic component forms by the plastic 38 is formed, the ribs 54 , In the second embodiment, the tempering channels 36c at least along the first direction through the plastic 38 or through the ribs 54 limited.

3 shows a third embodiment.

As in the second embodiment, the walls are also in the third embodiment 22 no tempering channels, wherein the tempering channels 36c on the ground 30 are provided. Further, the plastic forms 38 Ribs 54 , which the tempering channels 36c at least partially, in particular at least predominantly or completely, at least along the first direction. This means that the tempering channels 36c at least partially, in particular at least predominantly or completely, through the plastic at least along the first direction 38 are limited.

The wall element formed from the metallic material 34c is in the third embodiment, a metallic plate, which is also referred to as another bottom plate. Thus, in the third embodiment, the wall element 34c and the outer wall element 56 respective panels, in particular floor panels, which are also referred to as structural panels.

However, while the wall element 34c is formed of a metallic material, is the outer wall element 56 formed in the third embodiment of a plastic. The structural panels are separate from the intrinsically rigid plastic components or with the inherently rigid plastic 38 trained and connected to this. Here is the wall element 34c like that with the plastic 38 connected to that plastic 38 to the wall element 34c is sprayed or is. After making the plastic component characterized in that the plastic 38 to the wall element 34c is injected, the outer wall element 56 with the plastic 38 or connected to the plastic component.

Further, the plastic forms 38 in the third embodiment, floor elements 60 of the soil 30 and thus the wall 32 so the recording room 18 in the third direction partly through the wall element 34c and partly by the floor elements 60 and thus the plastic 38 is limited. As well as the second wall elements 58 through the plastic 38 are formed, the third embodiment is based on a plastic base body, wherein the base housing in the third embodiment, the wall elements 58 , the floor elements 60 and the ribs 54 or the plastic component comprises. In the third embodiment, this is made of the plastic 38 formed and preferably integrally formed basic housing produced by injection molding or by injection molding, in the context of the plastic 38 to the wall element 34c is injected.

The example formed as aluminum sheet with an exemplary wall thickness of 1 millimeter wall element 34c is for example bent over and thereby with the plastic component or with the inherently rigid plastic 38 connected and at least partially of the plastic 38 overmoulded or injected.

By injection molding, for example, the temperature control channels 36c be produced as a complex and three-dimensional radiator structures in a cost effective manner, so that, for example, a particularly advantageous uniform distribution of the temperature control can be realized.

4 shows a fourth embodiment of the housing 10 , Out 4 is particularly well the previously described sandwich construction of the soil 30 or the wall 32 recognizable. In the fourth embodiment, a tempering line through which the temperature control medium flows is provided 62 provided, which, for example, the connection 48 is. The temperature control line 62 is partially through the outer wall element 56 and partly by the plastic 38 limited or formed, wherein the plastic 38 also the respective second wall element 58 forms. Thus, the fourth embodiment of the above-mentioned basic plastic housing.

The outer wall element 56 is for example via respective welded joints with the respective rib 54 connected so that, for example, the outer wall element 56 with the plastic 38 or welded to the plastic component and is thereby connected.

The outer wall member constituting the aforementioned structural plate 56 may be formed of a plastic. Overall, it can be seen that the case 10 is designed as a hybrid component, since it is both the metallic material and the plastic 38 having. In particular, it is conceivable that there outer wall element 56 itself is designed as a hybrid component, so that, for example, the outer wall element 56 is formed of a plastic and a metallic material, which with the plastic, from which at least a part of the outer wall element 56 is formed, is connected. In other words, it is conceivable that the outer wall element 56 exclusively of a plastic, exclusively of a metallic material or else of a metal-plastic combination, in particular of an aluminum-plastic combination, and thus formed per se as a hybrid component.

At an in 6 shown sixth embodiment and a in 7 shown seventh embodiment, the outer wall element 56 formed from the metal-plastic combination described above and thus formed per se as a hybrid component. In this case, the outer wall element comprises 56 a metallic part 64 , which is formed for example of a metallic material, in particular a light metal such as aluminum. Furthermore, the outer wall element comprises 56 a plastic part 66 which is formed of a plastic. In the plastic, from which the plastic part 66 is formed, it may be the plastic 38 act, however, is the plastic part 66 per se one separately from the plastic 38 trained and, for example, with the plastic 38 connected component. The metallic part 64 and the plastic part 66 are connected. As with the case 10 plastic 38 , the metallic wall element 34c and the outer wall element formed as a hybrid component 56 are used, a double hybrid solution is provided in the sixth embodiment and in the seventh embodiment, by means of which different thermal expansions can be kept particularly low.

In the sixth embodiment, the tempering line 62 partly through the wall element 58 and the ribs 54 plastic forming 38 and partly through the plastic part 66 limited. On the other hand, in the seventh embodiment, the temperature control line 62 at least predominantly, in particular completely, by the plastic 38 limited. Under the metal-plastic combination described above is to be understood that the outer wall element 56 is designed here as a metal hybrid component.

To a particularly advantageous adhesion of the plastic 38 for example, to the respective wall element 34a-c to realize, is the respective wall element 34a-c for example, before the injection molding of the plastic 38 by at least one or more coatings, by a mechanical processing and / or an optical processing such as the laser previously described pretreated, whereby, for example, the surface structuring O made or the primer on the subarea T is applied.

A distribution system for distributing the temperature control to the Temperierkanäle 36a-c For example, it can be integrated into the lower structural plate and / or into the upper structural plate by injection molding, whereby the distribution system can be hydraulically balanced by injection molding.

The lower structural plate or the outer wall element 56 can with the ribs 54 or be connected to the plastic component mechanically and / or welding technology, whereby, for example, the temperature control channels 36c can be represented as a cooling or tempering structure. By using injection molding, the tempering structure can be adapted to the respective requirements of the temperature control of the component. As described above, the lower structural plate can be designed as an injection molded part and thus exclusively made of a plastic or as a metal and hybrid component and consequently the plastic part 66 or the metallic part 64 include. The case with the case 10 realizable temperature, in particular cooling, has no immediate or closed interfaces with the composite system to the designated as well basic housing.
