Description

[0001] The invention relates to a storage container designed to hold a pasty or viscous medium. Furthermore, the invention relates to a storage device with multiple storage containers. Finally, the invention relates to a motor vehicle comprising at least one storage container or at least one storage device.

[0002] A storage container of this type serves to hold and specifically release a pasty or viscous medium. Such a pasty or viscous medium can, for example, be an energy storage medium, comprising a pasty or viscous carrier mass with an energy carrier held therein, e.g., dissolved or bound. One example is hydrogen as an energy carrier, which can be used, for example, for propulsion purposes in a vehicle. Such a storage container can therefore be used in a vehicle as an energy storage device, in which the energy carrier is held in the pasty or viscous carrier medium and released from the storage container for consumption purposes and subsequently further processed, i.e., dissolved from the carrier mass and then further processed for propulsion purposes.The tightness of the storage container must be ensured in order to prevent the pasty or viscous medium and with it, for example, the energy carrier contained therein from escaping uncontrollably.

[0003] DE 10 2006 009 113 A1 discloses a device for melting a meltable element, in particular an adhesive. The device comprises a container containing the element, having at least one heating element and an outlet for the melt. The heating element is provided in the bottom of the container, which is designed as a metal cylinder, and melts only the lower region of the adhesive block located on it, while an upper region of the adhesive block remains solid. To ensure that the adhesive block is melted consistently, a pressure plate presses down on the adhesive block from above. It is connected via a spindle to an electric motor, which is preferably a servo motor. This allows the pressure plate to be moved precisely, moved slightly backward, and precisely adjusted. This enables precise pressure control and thus accurate metering of the molten adhesive.

[0004] EP 4 299 508 A1 describes a system for providing energy. This system comprises a device for providing gaseous hydrogen, which comprises a first container for providing a solid metal borohydride, a reactor for releasing hydrogen gas from the metal borohydride, a second container for receiving the spent metal borohydride, and a consumer in which the hydrogen gas is oxidized, releasing energy. A transport device is provided downstream of the first container, with which the metal borohydride is removed from the first container and fed to the reactor. The reactor has a water supply for humidifying the metal borohydride, a device for providing a catalyst, and a removal device for removing hydrogen gas.

[0005] The invention is based on the problem of providing a suitable storage container.

[0006] To solve the problem, according to the invention, a storage container is provided, designed to hold a pasty or viscous medium, comprising a receiving body and a lid closing the latter, wherein at least one dispensing opening for the medium is provided on the lid, and a discharge device for conveying the medium to the dispensing opening, which has a piston-like discharge element movable in the receiving body, via which the medium can be pressed to the dispensing opening, wherein the discharge element is sealed to the receiving body via at least one sealing element and can be cooled at least locally via a cooling device.

[0007] The storage container comprises a receiving body and a lid that closes it. The lid is provided with a corresponding discharge opening for the pasty or viscous medium. In the assembled position, for example, a further line is connected to the lid, via which the pasty or viscous medium is connected to a downstream processing unit. A movable, piston-like discharge element is provided in the receiving body, via which the pasty or viscous medium can be pressed, i.e. conveyed, to the discharge opening. The piston-like discharge element can be moved linearly within the receiving body, so that appropriate pressure can be applied to the medium through which it can be discharged. A gap, albeit narrow, inevitably remains between the discharge element and the inner wall of the receiving body, which gap is sealed by at least one sealing element.There is a risk of leakage at this point, which is already counteracted by the sealing element, but it must nevertheless be ensured in any case that no medium can escape at this point. To ensure this, a cooling device is provided by which the discharge element can be cooled. Since the pasty or viscous medium is in contact with the discharge element at least in the area where the gap to the receiving body is created, i.e. where the sealing element is arranged, the pasty or viscous medium can be cooled by the discharge element, and if necessary also the sealing element, which in turn can be used to cool the pasty or viscous medium present at the gap area. By cooling the medium in this way, particularly in the gap area, the viscosity of the medium can be increased at least locally in the gap area, i.e. it becomes more viscous or even more pasty.This increase in viscosity inevitably reduces the fluidity of the medium, reliably preventing it from passing through the gap additionally sealed by the sealing element. The discharge element can therefore easily convey the medium along its entire stroke and discharge it through the discharge opening.

[0008] The medium, for example, has a viscosity of at least 10,000 mPas, making it at least as viscous as honey, or even more viscous, almost pasty. The storage container can, of course, be reversibly refilled after the medium has been removed, so it can be used in a vehicle without any problems.

[0009] The receiving body itself preferably has a cylindrical interior or delimits such a cylindrical interior, wherein the dispensing element has a cylindrical shape. The storage container thus forms a piston-cylinder unit in the manner of a cartridge, wherein the piston is formed by the dispensing element and is linearly movable in the receiving body forming the cylinder. The gap between the dispensing element and the inner wall of the receiving body is annular so that a corresponding annular sealing element can be used. The dispensing opening is preferably located centrally on the lid. The receiving body, and optionally also the lid, are preferably made of metal, for example aluminum, although a plastic version is also readily possible.Due to the cylindrical design of the receiving body, it can be easily formed from an extruded profile, for example, made of aluminum or a similarly sturdy plastic. The discharge element, i.e., the piston, is preferably made of metal, as metal is a good thermal conductor, thus providing an efficient cooling effect. It is advantageous if the inner wall of the receiving body is provided with a suitable coating, which, for example, is not wetted by the pasty or viscous medium or along which the medium can slide more easily, thus facilitating conveying.

[0010] The discharge element itself is conveniently movable via a motorized actuator, allowing it to be positioned very precisely using a suitable control device. This allows the pressure inside the container to be precisely adjusted and controlled, and ultimately also the pressure with which the medium is discharged from the discharge opening.

[0011] The discharge element is expediently part of a spindle drive, comprising a spindle coupled to the discharge element, along which the discharge element is movable, wherein the spindle can be driven in rotation via the actuating element. The discharge device is therefore designed as a spindle drive, with an axially fixed spindle and a piston-like discharge element, which is designed, for example, as a disc and is movable along the spindle. The spindle is coupled to the drive motor so that it can be rotated about its longitudinal axis, whereby, depending on the direction of rotation, the discharge element coupled to the spindle is moved towards the lid or away from the lid. The mechanical coupling is most simply designed as a toothed connection, wherein the discharge element engages with its toothing directly in the threaded spindle toothing or is guided via balls arranged in between.Alternatively, a toggle lever mechanism or another mechanical mechanism controlled by a drive motor can be provided as the discharge device.

[0012] If a spindle drive is used, it is advisable to also provide a corresponding seal in the coupling area between the discharge element and the spindle. The discharge element can therefore be sealed radially to the inner wall of the receiving body via at least one first sealing element and to the spindle via at least one second sealing element. In this case, there is not only a seal to the inner wall of the receiving body, but also to the spindle, so that both gap or passage areas through which the medium could pass are correspondingly sealed. However, as a result of the cooling of the discharge element, the resulting gap area at the coupling point between the discharge element and the spindle is inevitably also cooled, so that the additional increase in viscosity is also achieved there, and complete sealing is ensured by the sealing element there on the one hand and by the local increase in viscosity on the other.

[0013] As described, a central feature is the cooling of the discharge element, so that cooling of the medium in the respective gap area can inevitably be achieved via the cooled discharge element. The cooling device through which a coolant can flow can be attached to the discharge element itself. This means that on the side of the discharge element facing away from the cover, which is designed, for example, in a disc-shaped manner, a corresponding cooling device is arranged, via which the discharge element can be cooled. A suitable coolant can flow through the cooling device, i.e., if integrated into a motor vehicle, it can be supplied with coolant from an air conditioning system, or it can be integrated into its own coolant circuit. In an alternative embodiment, the discharge element can also be part of the cooling device and the discharge element itself can be flowed through by the coolant.In this case, the discharge element is partially hollow or designed with cooling channels, or as a completely hollow body, allowing the coolant supplied via the coolant circuit to flow through and be discharged again. In this case, the discharge element is cooled directly, as it is part of the overall coolant circuit.

[0014] As described, the risk of unwanted leakage only exists in the area where there is a gap between the discharge element and at least the inner wall of the receiving body, and possibly also to the spindle of the spindle drive, if provided. This means that ultimately an increase in viscosity through local cooling of the pasty or viscous medium is only sufficient in these areas. To ensure this, at least one insulating element can be provided on the discharge element on the side facing the medium. This insulating element insulates the discharge element over a large area from the pasty or viscous medium, so that no cold transfer occurs there, and thus the viscosity of the medium is not increased there, which could sometimes have a detrimental effect on the discharge capacity if the storage container is largely empty.A cold transfer is only possible in the radially outer edge area, i.e. in the gap area towards the receiving container, or, if provided, in the radially inner area, i.e. in the gap area towards the spindle, so that only a local change in viscosity occurs.

[0015] As long as the medium has a viscosity that is low enough to be conveyed through the dispensing opening without any problems and to then transport or process it further, no additional measures are required to adapt the viscosity of the medium in the dispensing element. However, for example when the storage container is used in a motor vehicle, the temperature of the medium can sometimes vary greatly due to the ambient temperature, i.e. the medium can cool down, which increases the viscosity. If the cooling is too great, the viscosity can be so high that the medium can only be discharged inadequately from the dispensing opening. To counteract this, an expedient development of the invention provides for at least one heating device to be provided, via which at least a section of the lid and / or the receiving body can be heated.This at least one heating device can therefore be used to introduce heat into the medium as needed to locally reduce the viscosity, thus making it somewhat more fluid, and to adjust the viscosity so that acceptable discharge from the dispensing opening is possible. The one or more heating devices, as well as the motorized actuator, are expediently controlled via a common control device.

[0016] It is advantageous if the heating device has at least one heating element that runs at least around the dispensing opening. This quasi-annular heating element enables direct heat input in the area of ​​the dispensing opening, so that the volume of medium to be dispensed is heated accordingly and rendered fluid. The medium is thus heated locally in the area of ​​the dispensing opening. Alternatively, the lid itself can also serve as a heating element, i.e., the lid itself is made of a resistance heating material and can be directly energized for heating, or can be directly permeated with a fluid heating medium.

[0017] A particularly advantageous embodiment provides for several separately controllable heating elements, which are arranged concentrically to one another and run around the dispensing opening. The heating device on the lid is therefore segmented accordingly and divided into several concentric heating element rings. This allows heat to be applied over a smaller or larger area, so that a smaller or larger volume of medium can be heated depending on the number of ring-shaped heating elements in operation. This makes it possible to determine the required number of heating elements to be activated depending on the given temperature of the medium and to control the temperature balance accordingly. This is because the heatable medium volume is variable in this case.

[0018] Furthermore, at least one heating element can be provided surrounding the outside of the receiving body. This at least one further heating element serves to heat the remaining volume of the medium, whereby this volume heating is particularly useful at low outside temperatures, i.e., when the medium is generally cold and thus very viscous.

[0019] Here, too, it is conceivable to provide several separately controllable heating elements axially one after the other on the outside around the receiving body. Here, too, a cascade-like arrangement of annular heating elements around the preferably cylindrical receiving body is advantageous for a segmented design of the heating device, which in turn makes it possible to operate just one annular heating element or several heating elements, depending on the given situation, so that the actually heated volume can be selected variably. If the entire outer body is equipped with these additional heating elements, the entire container volume can also be used accordingly, if necessary. In conjunction with the preferably segmented lid heating, an optimized temperature balance can be controlled, which allows the best possible dispensing result.

[0020] Electrical resistance heating elements, i.e. resistance heating bands and the like, are preferably used as heating devices or heating elements, since the temperature can be regulated very quickly using such resistance heaters.

[0021] In this context, it is advantageous if at least one sensor element is provided for detecting temperature information, with at least one control device being provided that controls the operation of the cooling device and / or the heating device depending on the temperature information. Such a temperature element thus detects temperature information that serves to control the corresponding temperature control components, whether the cooling device for locally cooling the medium to increase viscosity or the heating device for locally heating the medium to reduce viscosity.

[0022] Preferably, at least one sensor element is arranged on the discharge element. This serves to measure the temperature, particularly in the area of ​​the radially outer seal and, if provided, the radially inner seal. Of course, more temperature sensors can also be provided to specifically measure the temperature at multiple positions. For example, several sensor elements can be distributed around the outer edge of the discharge element to measure the local temperature in the outer area, and, if provided, several sensor elements can be provided in the area of ​​the coupling to the spindle to measure the temperature locally there.

[0023] Furthermore, it is expedient to provide at least one sensor element on the lid in the area of ​​the dispensing opening. This allows the temperature of the lid to be measured locally, which in turn indicates the temperature of the medium. Of course, the sensor element can also be provided on the inside of the lid, so that the temperature of the medium is measured directly. In principle, sensor elements can also be provided inside the container to measure the temperature of the medium, for example, on the spindle or similar.

[0024] In addition to the storage container itself, the invention further relates to a storage device comprising a plurality of storage containers of the type described above. The plurality of storage containers thus form a larger-sized energy storage device that can be installed, for example, in a motor vehicle, for example in the underbody area, where the storage device designed like a larger storage battery can be arranged instead of an electrical storage device. The cartridge-like storage containers can, for example, be arranged next to one another in a row. They each have, for example, a length of 1 m or more, with a diameter of, for example, 15 cm or more, depending on the available space. Naturally, the larger the respective storage volumes of the individual storage containers, the greater the capacity of the storage device.

[0025] Advantageously, a common control device is provided via which the operation of the motorized actuating elements and / or the cooling devices and / or the heating devices of the plurality of storage containers can be jointly controlled.

[0026] Finally, the invention further relates to a motor vehicle comprising at least one storage container of the type described above or at least one storage device of the type described above. The one storage container or the storage device is connected to a corresponding processing device in which the released medium, i.e., the energy storage medium, is further transported and processed. The or each storage container contains a pasty or viscous medium comprising a pasty or viscous carrier medium with an energy carrier, in particular hydrogen, accommodated therein, for example, dissolved or bound.

[0027] Further advantages and details of the present invention will become apparent from the exemplary embodiments described below and from the drawings. These show: Fig. 1 a schematic diagram of a storage container according to the invention of a first embodiment, Fig. 2 a schematic diagram of a storage container according to the invention of a second embodiment, and Fig. 3 a schematic diagram of a storage device according to the invention in a motor vehicle according to the invention.

[0028] Fig. 1 shows a schematic diagram of a storage container 1 according to the invention designed to hold a pasty or viscous medium in a holding volume 2. The storage container 1 comprises a cylindrical holding body 3, which is made, for example, from an extruded profile made of aluminum or plastic. On one side, the holding body 3 is closed off by a lid 4, wherein the lid 4 has a discharge opening 5 through which the medium located in the holding volume 2 can be pressed out. For this purpose, a discharge device 6 is used, comprising a piston-like discharge element 7, which in the example shown is designed as a cylindrical disc that is arranged inside the holding body 3 and is longitudinally movable therein.The discharge element 7 is part of a spindle drive 8, which further comprises a spindle 9, i.e., a threaded spindle, to which the discharge element 7 is coupled, for which purpose a corresponding threaded engagement of the internal thread of the discharge element 7 with the external thread of the threaded spindle 9 is provided. The spindle 9 is fixed in position and connected to a motorized actuating element 10, via which the spindle 9 can be rotated. Due to the threaded engagement, the discharge element 7 moves along the spindle, so that the actuating movement can pressurize and expel the medium 11 located in the receiving volume 2.

[0029] A first sealing element 12 is arranged between the discharge element 7 and the receiving body 3, sealing the resulting gap between the outer circumference of the discharge element 7 and the inner wall 13 of the receiving body 3. Likewise, a suitable sealing element 14 is provided in the coupling area between the discharge element 7 and the spindle 9, sealing any gap that may arise there. This is because it is necessary to prevent the pressurized medium 11 from escaping through any gap on this side.

[0030] Furthermore, a cooling device 15 is provided, via which the disc-shaped discharge element 7 can be cooled. The cooling device 15 has an annular heat sink 16 through which a coolant can flow, which is in direct contact with the discharge element 7. The heat sink 16 is integrated into a coolant circuit 17, of which, for the purposes of simplification, only a pump 18 is shown, which circulates the coolant. The coolant circuit 17 naturally also has a compressor, a condenser, an evaporator, etc. In any case, the discharge element 7 can be cooled as a whole via the heat sink 16, i.e., the cooling device 15. This also allows the medium present in the area of ​​the respective sealing elements 12, 14 to be cooled, i.e., the medium volume present directly in the gap area.This cooling significantly increases the viscosity of the medium in the gap area, making it even more viscous, which, in conjunction with the respective sealing element 12, 14, reliably prevents the medium from escaping from the respective gap.

[0031] In order to limit the cooling of the medium to the respective gap area only, an insulating element 19 is arranged on the side of the discharge element 7 facing the receiving volume 2, which insulating element is dimensioned such that a large-area thermal insulation is provided between the discharge element 7 and the medium 11 located in the receiving volume 2, and direct contact between the cooled discharge element 7 and the medium 11 is only provided in the area of ​​the respective sealing element 12, 14. This means that cold is introduced and thus an increase in viscosity only takes place in a very small area there, while the remaining volume of the medium 11 is not cooled.

[0032] Furthermore, two heating devices 20, 21 are provided, wherein heating device 20 serves to heat the lid 4, while heating device 21 heats the receiving body 3 and thus primarily serves to heat the volume. The heating device 20 comprises a plurality of separately controllable heating elements 22, which are arranged concentrically around the dispensing opening 5 and are designed as resistance heating elements. The heating device 21 also comprises a plurality of separately controllable heating elements 23, which are arranged in a ring around the outside of the cylindrical receiving body 3. Both heating devices 20, 21 are therefore segmented via the individual heating elements 22 and 23, respectively. Due to the segmented design, variable heating of the lid 4 and / or the receiving body 3 and thus of the volume is possible in order to appropriately temperature-control the medium 11, for example if this is necessary due to the ambient temperature or the medium temperature.If the ambient temperature is too low, the medium 11 cools down excessively, and its viscosity increases excessively, which adversely affects the discharge process. This can be counteracted by heating a variable volume of the medium 11 over a small or large area.

[0033] For control purposes, a common control device 24 is provided, via which, on the one hand, the motorized actuating means 10 and the cooling device 15 or the coolant circuit 17 can be controlled, but on the other hand also both heating devices 20, 21 or, individually, all separate heating elements 22, 23 can be controlled. Accordingly, the control device 24 can control, on the one hand, the complete cooling operation and, on the other hand, also the complete heating operation, as well as the conveying operation of the discharge device 6.In order to be able to control the cooling device 15 as well as the heating devices 20, 21 accordingly in order to optimally adjust the temperature of the medium 11, in the example shown, two temperature sensors 25 are provided on the discharge element 7 in the respective gap area. These sensors can be used to detect, for example, the temperature of the discharge element 7 or the temperature of the medium 11 in this area in order to determine, based on the temperature information, whether or not additional cooling is required to increase the viscosity and thus improve the sealing effect. The temperature sensors 25 communicate with the control device 24, which processes the corresponding temperature information and controls the cooling device 15 or the coolant circuit 17 accordingly.

[0034] Furthermore, at least one temperature sensor 26 is provided, which is arranged on the lid 4 in the region of the dispensing opening 5 and also communicates with the control device 24. This temperature sensor 26 detects the temperature of the lid 4 in the region of the dispensing opening 5, which is indicative of the temperature of the medium 11. Alternatively, it can also directly detect the temperature of the medium 11. This can be used to determine the ultimate viscosity of the medium 11 in the region of the dispensing opening 5, which should not exceed a certain viscosity value so that it is not too viscous or pasty, which would impede or prevent dispensing. Based in particular on this information, the heating elements 22 of the heating device 20 can be controlled, and if necessary, also the heating elements 23 of the heating device 21, in order to appropriately control the temperature of the medium 11.The segmented design of the heating devices 20, 21 via the heating elements 22, 23 and their individual controllability allows for very flexible temperature control. Volume heating and thus temperature control of the medium volume can be achieved by controlling, in particular, the heating elements 23, which are arranged along the outer side of the receiving body 3 and, viewed axially, are arranged next to one another, whereby more heating elements than those shown can extend along the outer side. Information from the temperature sensors 25 is also expedient for this purpose, just as further temperature sensors, via which the medium temperature in the volume can be measured, can naturally also be provided and can communicate with the control device 24. For example, such temperature sensors can be installed on the spindle 9 or in the inner wall 13.

[0035] In the initial state, the receiving volume 2 is completely filled, and the discharge element 7 is in a retracted position. If the medium 11 is to be discharged, the spindle drive 8 is operated, controlled by the control device 24, and the discharge element 7 is successively pushed forward toward the cover 4, so that the medium 11 is pushed out of the discharge opening 5 and conveyed into a connecting line for further processing. Once the storage container 1 is empty, it can of course be refilled, i.e., fully recharged. This is, of course, possible in the installed state, for example, when used in a motor vehicle.

[0036] Medium 11 can be an energy storage medium consisting of a correspondingly pasty or viscous carrier mass in which an energy carrier, in particular hydrogen, is dissolved or bound. This energy carrier is extracted and further processed in a downstream processing device, for example, to power a motor vehicle.

[0037] Fig. Figure 2 shows a configuration of a storage container 1 of a second embodiment. The basic structure corresponds to the configuration according to Fig. 1, which is why the same reference numerals are used for comparable components and otherwise, unless otherwise described, refer to the explanations Fig. 1 is referred to.

[0038] The storage container 1 comprises a receiving body 3 and a lid 4 for defining a receiving volume 2, in which a pasty or viscous medium 11 is accommodated. An integrated discharge device 6 is provided with a piston-like discharge element 7, which in turn is part of a spindle drive 8 with a threaded spindle 9 and servo motor 10. The corresponding gaps are sealed by sealing elements 12, 14, and an insulation element 19 is also provided.

[0039] The discharge element 7 can in turn be cooled via a cooling device 15 and is integrated into a coolant circuit 17, whereby the discharge element 7 is supplied directly with the coolant. The discharge element 7 is designed, for example, as a disc-shaped hollow body or has corresponding cooling channels so that the coolant can circulate through the hollow body or the cooling channels. A separate heat sink, as in the embodiment according to Fig. 1, is not provided here.

[0040] A heating device 20 is also provided, via which the cover 4 can be heated. The cover 4 itself serves as a heating element, i.e., it is supplied with current and thus is resistance heated. Alternatively, the supply of a liquid heat medium, for example, heated water or the like, would also be conceivable. Separate resistance heating elements, as in the embodiment according to Fig. 1 are not required here. Control is again provided via a control device 24, which communicates accordingly with the temperature sensors 25, 26 also provided here. Although not provided, a heating device 21, via which the outside of the receiving body 3 can be heated, can of course also be provided in this embodiment.

[0041] Fig. Finally, Figure 3 shows a schematic diagram of a motor vehicle 27, shown here only in dashed lines, in which a storage device 28 according to the invention is arranged, comprising a plurality of separate storage containers 1, which are arranged next to one another in the manner of a storage block. The storage containers 1 are only shown in principle; they are, for example, according to the embodiments according to Fig. 1 or Fig.2 and is suitably connected to a common coolant circuit 17. Only a common control device 24 is shown, via which all elements of the storage containers 1 to be controlled are controlled, i.e., on the one hand, the coolant circuit 17 or the cooling devices 15, and on the other hand, all heating devices 20, 21, etc.

[0042] It is further shown that corresponding lines 30 are connected to the discharge openings 5 ​​of the individual storage containers 1, which open into a common continuing line 31, which in turn leads to a device that further processes the discharged medium.
