Definitions
- Mounting system for attaching a cryogenic container to a vehicle frame
- the invention relates to a system comprising a cryocontainer with a lateral surface and a first and a second end cap, at least two support brackets, each with a mounting side for mounting on a vehicle frame, at least two tensioning straps for fastening the cryocontainer on the support brackets, the cryocontainer with the lateral surface rests on the support brackets and is encompassed by the tensioning straps over the lateral surface, the system further comprising at least a first and a second operating component of a removal system, filling system, conditioning system and/or venting system of the cryogenic container.
- cryogenic tanks mount cryogenic tanks on a motor vehicle, in which liquefied gas (e.g. LNG, “Liquid Natural Gas”) is stored, which is used, for example, as fuel for the motor vehicle.
- liquefied gas e.g. LNG, “Liquid Natural Gas”
- a connecting line is routed into each of the cryocontainers, via which the cryocontainer can be filled.
- cryogenic tanks are mounted on support brackets on the side of the vehicle between the front and rear axles and are surrounded by straps.
- US 2015/0096977 A1 shows such a mounting system with support brackets and straps.
- cryocontainers mounted in this way, operating components such as a heat exchanger can also be used, which expands the cold, liquid-state cryofluid removed from the cryocontainer and thus brings it to a temperature so that the cryofluid is suitable as fuel for the vehicle's engine.
- the operating components are arranged behind the end caps of the cryocontainer, but this means that the cryocontainer has to be made shorter and therefore less fuel can be carried.
- the heat exchanger can be designed in the form of a rod and arranged parallel to the cryogenic container on its lateral surface.
- Such an arrangement is known, for example, from the "Iveco LNG Stralis" system, in which the heat exchanger is arranged on the top of the cryogenic container and faces the vehicle frame.
- the heat exchanger can also be arranged on the side facing away from the vehicle frame, as is shown, for example, in EP 3 121 505 B1.
- a system comprising a cryocontainer with a lateral surface and a first and a second end cap, at least two support brackets, each with a mounting side for mounting on a vehicle frame, at least two straps for fastening the cryocontainer to the support brackets, the cryocontainer with the lateral surface rests on the support brackets and is encompassed by the tensioning straps over the lateral surface, the system also comprising at least a first and a second operating component of an extraction system, filling system, conditioning system and/or venting system of the cryogenic container, the first and the second operating component located only on that side of an outermost strap facing the nearest end cap, the first operative component and the second operative component being at least partially, preferably fully, attached at different locations from: at the Lateral surface on an upper side of the cryocontainer in the operating position, facing away from the assembly side, on the lateral surface on an upper side of the cryocontainer in the operating position, facing away from the assembly side,
- the system according to the invention has the advantage that as many operating components as possible can be arranged close to the cryocontainer, but do not have to cross over or under the straps.
- This advantage is only achieved through the combination of two measures.
- the first measure is that the operative components of the cryogenic vessel are located end-only, i.e. on that side of an outermost strap facing the nearest end cap, whereby the operative components do not cross the straps.
- the operating components are arranged in a distributed manner, since there is only extremely little space available for arranging the operating components if the operating components are arranged purely at the ends.
- one of the operating components can be arranged at least partially on the lateral surface of the cryocontainer and another either in a cap gusset if the end cap is convexly curved, or at least partially on the lateral surface on a correspondingly different side of the cryocontainer.
- the solution according to the invention has the advantage that the space required in the longitudinal direction of the cryocontainer is extremely small, which, in combination with the first measure explained above, has the advantage according to the invention of easy disassembly of the cryocontainer brings with it.
- cryocontainer with the operating components mounted on it can now be used as a compact unit that can be placed as a whole on the support brackets.
- the operational components do not have to be dismantled in order to attach and detach the cryocontainer to and from the vehicle.
- the straps do not have to be removed in order to service or replace one of the operating components, as would be necessary if the straps were guided over the operating components.
- “At least partially at the points mentioned” is understood to mean that an operating component could, for example, protrude beyond the lateral surface on the side facing away from the nearest tightening strap and, for example, protrude beyond one of the end caps or could protrude even further.
- the first and/or the second operating component are preferably located at least partially, preferably completely, in gussets that are enclosed between the lateral surface and the smallest possible imaginary cuboid circumscribing the lateral surface, the side surfaces of which are arranged horizontally or vertically in the operating position.
- This solution further defines the proximity of the operating components on the cryocontainer and it can be ensured in particular that not only the cryocontainer but also its operating components are located in an installation space that is available next to the vehicle frame.
- first and the second operating component can be connected by means of a connecting line, which is preferably routed in the circumferential direction of the lateral surface, and can particularly preferably be fluidly connected. It can thereby be provided that the operating components are connected, although they are not arranged directly next to one another.
- several operating components of the removal system can be distributed over the circumference of the lateral surface through the connecting line, which is particularly preferred since these operating components generally require a large amount of space.
- first and the second operating component are surrounded by a common cover. This eliminates the need for two separate covers and allows the operational components to be accessed simultaneously by removing only one cover.
- At least one of the operating components is arranged on the side of the cryocontainer facing away from the assembly side and the system also includes a connecting line which is connected to this operating component and is preferably routed in the circumferential direction of the lateral surface above or below the cryocontainer to the vehicle frame or behind or in front of the end cap led to the vehicle frame.
- a suitable line routing can also be provided for the connecting line without crossing the tightening straps.
- the respective nearest end cap has a convex curvature and the connecting line is routed through a gusset that is enclosed between the end cap and an imaginary cuboid that is as small as possible above this end cap.
- the available installation space can be used particularly effectively.
- the first and second operating components are particularly preferably selected from the list: heat exchanger, economizer, pressure relief valve, non-return valve, manual valve, electromechanical valve, electrical switch for this purpose, in particular emergency stop switch, valve module comprising at least two valves, filler neck, vent connection, drain connection, pump , Pressure build-up device, manometer and control unit for at least one of the aforementioned operating components.
- the heat exchanger is typically required to vaporize withdrawn cryofluid and thereby raise its temperature, which is generally necessary since the engine requires a certain minimum cryofluid temperature.
- An economizer is understood to be a device that controls whether gas-phase or liquid-phase cryogenic fluid is withdrawn from the cryogenic vessel in order to regulate the pressure in the cryogenic vessel.
- At least one pressure relief valve typically two pressure relief valves, are provided to ensure that cryofluid can escape from the cryocontainer when the pressure in the cryocontainer exceeds a threshold value.
- Check valves are provided, for example, to prevent cryofluid that has already been removed from flowing back into the cryocontainer.
- Manual valves can be provided, for example, to manually stop further withdrawal of cryofluid.
- Cryofluid is introduced into the cryocontainer via the filling coupling.
- Cryogenic fluid in the gas phase can be removed from the cryogenic container via the ventilation connection, in order to manually reduce the pressure in the cryogenic container and specifically discharge the gas phase.
- the pump and/or the pressure build-up device are usually used as part of a conditioning system in order to regulate the state (pressure, temperature, etc.) of the cryogenic fluid in the cryogenic container.
- the control device can be provided in order to control operating components, in particular valves, of the withdrawal system, filling system, conditioning system and/or venting system.
- the first operating component is particularly preferably a heat exchanger and the second operating component is a filling nozzle (filling coupling), which each preferably lie at least partially above the lateral surface of the cryocontainer and are distributed over the circumference of the lateral surface.
- the first operating component is a heat exchanger, which is at least partially arranged on the lateral surface
- the second operating component is a Filling clip, which is preferably at least partially arranged on the lateral surface. It goes without saying that further operating components can be present at other points of the cryogenic container or next to the heat exchanger or the filling nozzle.
- a vehicle with a vehicle frame and a system of the aforementioned embodiments can thus be created by the invention, with the support brackets being mounted on the vehicle frame and the cryocontainer being fastened to the support brackets by means of the tensioning straps.
- FIG. 1 shows a vehicle with cryocontainers mounted on it in a plan view.
- FIG. 2 shows the assembly of cryocontainers on vehicles according to the prior art in a perspective view.
- FIG. 3 shows the assembly of cryocontainers on vehicles according to the prior art in a plan view.
- FIG. 4 shows a first embodiment according to the invention in a perspective view.
- FIG. 5 shows the arrangement of FIG. 4 in a side view.
- FIG. 6 shows the arrangement of FIG. 4 in a rear view.
- FIG. 7 shows a second embodiment according to the invention in a perspective view.
- FIG. 8 shows the arrangement of FIG. 7 in a side view.
- FIG. 9 shows the arrangement of FIG. 7 in a rear view.
- FIG. 10 shows a third embodiment according to the invention in a side view.
- FIG. 11 shows the arrangement of FIG. 10 in a rear view.
- FIG. 1 shows a vehicle 1 with a vehicle frame 2 on which two cryocontainers 3, 4 are mounted. In general, however, only one cryocontainer 3 can be mounted on one side of the vehicle frame 2 .
- the cryogenic vessels 3, 4 store cryogenic fluid used as fuel for an engine of the vehicle 1, so the cryogenic vessels 3, 4 are also referred to as fuel tanks.
- the cryofluid stored in the two cryocontainers 3, 4 can be, for example, hydrogen, so that the respective cryocontainer 3, 4 is a hydrogen container, or the cryofluid can be LNG (liquefied natural gas), so that the cryocontainer 3, 4 is an LNG container.
- the cryocontainer 3, 4 is thus designed to use cryofluid at temperatures of, for example, below 150 Kelvin, in the case of hydrogen even below 50 Kelvin or below 30 Kelvin or substantially 20 Kelvin.
- cryogenic container 3, 4 could be designed, for example, to store sLH2 (subcooled liquid hydrogen) or CcH2 (cryo-compressed hydrogen) and thus also be designed for correspondingly high pressures, eg for maximum pressures between 5 bar and 350 bar.
- the cryocontainers 3 , 4 are arranged on the vehicle 1 in an installation space which is present on the side of the vehicle frame 2 between front wheels 6 mounted on a front axle 5 and rear wheels 8 mounted on a rear axle 7 .
- the installation space is limited laterally by the vehicle frame 2 or the width B of the vehicle 1, e.g. the width of the driver's cab of the vehicle 1.
- the available installation space is also limited at the bottom by a minimum ground clearance height and at the top by an upper edge of the vehicle frame 2, since the cryogenic container 3, 4 should not protrude over the vehicle frame 2, for example to prevent collisions with a semi-trailer (not shown).
- cryogenic containers 2 It is known from the prior art summarized in Figures 2 and 3 to mount the cryogenic containers 2 within the installation space mentioned on the vehicle frame 2 by mounting the cryogenic containers 3, 4 on support brackets 9 and clamping them to the support brackets 9 using tensioning straps 10.
- the cryocontainers 3, 4 comprise a substantially cylindrical lateral surface 16 and have convex end caps 17, 18 (shown in FIG. 2 with planar end caps only for the sake of clarity, which was not previously known in this form).
- FIGS. 2 and 3 It can also be seen from FIGS. 2 and 3 that not only the cryocontainer 3, 4, but also other operating components 11, 12 can be stored in the installation space mentioned. As shown, for example, a heat exchanger 11 and a pressure indicator 12 of the extraction system of the cryocontainer 3, 4 are also mounted on the cryocontainer 3, 4 within the installation space mentioned. If necessary, connecting lines 20 can be routed from the operating components 11, 12 via the cryogenic container 3, 4 to the vehicle frame 2, for example to supply cryogenic fluid to the engine of the vehicle 1 or to provide and dissipate heat exchange medium for the heat exchanger 11. It is known from the prior art to arrange all of these operating components next to one another for simple assembly, so that at least the heat exchanger 11 is arranged over the clamping straps 10 .
- the operating components to be arranged in the installation space mentioned can be parts of an extraction system, filling system, conditioning system and/or venting system of the cryogenic container 3, 4, such as a heat exchanger, economizer, pressure relief valve, non-return valve, manual valve, electromechanical valve, electrical Switch for this purpose, in particular emergency stop switch, valve module comprising at least two valves, filler neck, vent connection, drain connection, pump, pressure build-up device, pressure gauge and control unit for at least one of the aforementioned operating components. It can be seen that the large number of operating components take up a lot of space on or possibly also next to the cryocontainer 3, 4.
- FIGS. 4 to 9 it is therefore provided according to FIGS. 4 to 9 that at least a first and a second operating component 13, 14 are arranged at different points on the circumference of the cryocontainer 3, 4, which may be connected by means of a connecting line
- one of the operative components 13,14 may also be adjacent one of the end caps 17,18.
- the cryogenic container 3, 4 has an outer surface
- a strap 10 per support bracket 9 is used as a rule. As shown, the tightening straps 10 are guided around the lateral surface 16 in the circumferential direction, so that the cryocontainer 3 , 4 can be mounted on the vehicle frame 2 by means of the support brackets 9 .
- the support brackets 9 each have a mounting side 19 for mounting on the vehicle frame 2, which is opposite that side of the support brackets 9 on which the cryocontainer 3, 4 is intended to rest.
- the vehicle frame 2 has a surface that is complementary to the support brackets 9, so that the support brackets 9 can be mounted on it by means of the assembly pages 19.
- the mounting sides 19 are usually vertical, but could also be inclined if the vehicle frame 2 is designed accordingly.
- the support brackets 9 each have a curve which partially surrounds the cryocontainer 3, 4.
- the support bracket 36 can absorb part of the weight of the cryocontainer 3, 4 even without the tightening straps 10, with the tightening straps 10 obviously still being required to hold the cryocontainer 3, 4 on to tighten the support brackets 9.
- the rounding of the support brackets 9 should preferably be dimensioned in such a way that the support brackets 9 themselves do not protrude below the minimum ground clearance level.
- the support brackets 9 could also have a different shape than shown and, for example, also be straight, with the support brackets 9 already defining an operating position of the cryocontainer 3 , 4 on the vehicle frame 2 due to their design and the mounting side 19 .
- all operating components 13, 14 are arranged only on that side of an outermost clamping band 10 which faces the end cap 17, 18 which is closest. It can be seen from FIG. 4 that the tightening straps 10 on the outside right and outside on the left form the two outermost tightening straps 10 . Irrespective of whether the cryocontainer 3, 4 is mounted on the vehicle frame 2 by means of two, four, six or another number of straps 10, only two of the straps 10 will form the outer straps 10.
- Each of the outermost straps 10 now defines two sides, one facing the nearest end cap 17,18 and one facing away from the nearest end cap 17,18. If all operating components 13, 14 are now only arranged on that side of an outermost tightening strap 10 that faces the closest end cap 17, 18, it can be ensured that none of the operating components 13, 14 and also no connection line 20 of the operating components 13, 14 of the straps 10 must cross. Although the figures only show that the operating components 13, 14 are located at the right-hand outer edge of the cryocontainer 3, 4, operating components 13, 14 could alternatively or additionally also be located at the left-most edge of the cryocontainer 3, 4, i.e. on the left side of the leftmost strap 10.
- the invention therefore provides for arranging the operating components 13, 14 along the circumference of the cryogenic container 3, 4, i.e. the circumference of the lateral surface 16, in order to make better use of the available installation space.
- FIG. 4 shows, for example, that a first operating component 13 is arranged on a side of the cryocontainer 3, 4 that is at the top in an operating position and a second operating component 14 is arranged on a side that is at the bottom in an operating position.
- the operating position is already then well-defined as soon as the cryocontainer 3, 4 rests on the support brackets 9, since these define the position relative to the vehicle 1 through the mounting sides 19 and the shape, eg curvature.
- Both operating components 13 , 14 are each arranged on the side of the cryocontainer 3 , 4 facing away from the assembly side 19 , but could also be located on the side of the cryocontainer 3 , 4 facing the assembly side 19 .
- facing the assembly side 19 is synonymously understood to mean “facing the vehicle frame 2”.
- the terms “in an operating position on the top or bottom side of the cryocontainer 3, 4” are preferably understood in relation to a horizontal plane which essentially symmetrically divides the cryocontainer 3, 4 into an upper and a lower side.
- the terms “facing or facing away from the assembly side 19 in an operating position” are preferably understood in relation to a vertical plane which essentially symmetrically divides the cryocontainer 3 , 4 into a side facing or facing away from the assembly side 19 .
- the first operating component 13 is arranged on a side of the cryocontainer 3, 4 facing away from the assembly side 19 and the second operating component 14 is arranged on a side of the cryocontainer 3, 4 facing the assembly side 19.
- Both operative components 13, 14 are placed on the operatively-up side, but could also be on the operatively-down side.
- the operating components 13, 14 are therefore distributed around the circumference of the lateral surface 16 and the available installation space is better utilized. It goes without saying that more than two operating components 13, 14 can also be arranged around the circumference of the lateral surface 16. For example, two, three or four of the following operating components 13, 14 can be arranged on the lateral surface 16: A first operating component 13 at the top and facing away from the mounting side 19, a second operating component 14 at the bottom and facing away from the mounting side 19, a third operating component at the top and facing away from the mounting side 19 facing; and a fourth operative component below and facing the mounting side 19 .
- “Arranged on the lateral surface” means here that the operating components 13, 14 can be arranged either in direct contact or at a predetermined maximum distance, eg a maximum of 1 cm, 5 cm or 10 cm, from the lateral surface 16. Furthermore, “arranged on the lateral surface” is understood to mean that the respective operating component 13, 14 is at least partially arranged on the lateral surface and can also protrude beyond the lateral surface, for example in the longitudinal direction. Alternatively, the respective operating component 13, 14 also be arranged completely on the lateral surface 16 and do not protrude beyond the lateral surface 16 in the longitudinal direction.
- the cuboid Q is the smallest possible imaginary cuboid Q circumscribing the cryogenic container 3, 4 or the lateral surface 16, possibly also the tightening straps.
- the tightening straps 10 are also generally to be arranged in the available space.
- the cuboid Q is designed in such a way that all of its side surfaces are arranged horizontally or vertically in the operating position of the cryocontainer 3, 4. It can also be seen from the figures mentioned that there are four gussets ZI-Z4 between the cuboid Q and the lateral surface 16.
- the first operational component 13 is placed in one of the gussets and the second operational component 14 is placed in another of the gussets to achieve the distribution of the operational components 13, 14 around the circumference of the envelope surface 16.
- the operating components 13, 14 are at least partially, preferably completely, arranged in the respective gussets ZI-Z4. “At least partially” can preferably be understood to mean that although the operating components 13, 14 are located within the cuboid Q in a cross section along the longitudinal axis of the cryocontainers 3, 4, compare Figures 8 and 9, they also protrude beyond one of the end caps 17, 18 be able. Alternatively, “at least partially” can also be understood to mean that the operating components 13, 14 also protrude beyond the cuboid Q in a cross section along the longitudinal axis of the cryocontainers 3, 4.
- the two operating components 13, 14 are connected by means of a connecting line 15.
- the first operating component 13 is, for example, a connection piece or an economizer, via which cryofluid can be removed from the cryocontainer 3, 4, the removed cryofluid can be routed via the connecting line 15 to the second operating component 14, which is, for example, a heat exchanger, i.e. evaporator.
- the cryogenic fluid can be routed from the second operating component 14 to the vehicle 1, e.g. to an engine of the vehicle 1, via the connection line 20 shown.
- the connection line 20 is, for example, a connection piece or an economizer, via which cryofluid can be removed from the cryocontainer 3, 4
- the removed cryofluid can be routed via the connecting line 15 to the second operating component 14, which is, for example, a heat exchanger, i.e. evaporator.
- the cryogenic fluid can be routed from the second operating component 14 to the vehicle 1, e.g. to an engine of the
- the first operating component 13 can also be a control device and the second operating component 14 can, for example, be an electric economizer, a valve or the like.
- the connecting line 15 is an electrical one Connection for the transmission of signals and does not allow fluid communication.
- the control line can also be provided in addition to a fluid connection.
- connection line 20 In order to transfer cryogenic fluid to the vehicle 1 or its engine, the connection line 20 already mentioned can be provided. This can, for example, be guided to the vehicle frame 2 in the available installation space, for example through a gusset that is enclosed between the smallest possible imaginary cuboid or cylinder and the cryocontainer 3, 4 next to convex end caps, as is known from EP 3 121 505 B1.
- the connecting line 20 could also be routed under the cryogenic container 3, 4 (FIG. 4) or above the cryogenic container 3, 4 (FIG. 7) to the vehicle frame 2, from where the connecting line 20 can be routed to the engine.
- the connecting line 20 could be routed either within the available space if the cryocontainer 3, 4 has a correspondingly smaller diameter or shorter length, or outside of the available space, for example below or above the cryocontainer 3, 4 .
- Another possibility would be to run the connection line 20 in front of or behind the available space through an unused space that results from the rounding of the front wheel 6 or rear wheel 8, i.e. the connection line 20 is behind or in front of the end cap 17, 18 led to the vehicle frame 2.
- the connecting line 20 can be routed horizontally to the vehicle frame 2 from the highest or lowest point, compare the solid lines in Figure 6, or be adapted to the curvature of the cryocontainer 3, 4 and enter a gusset that is located on a side of the cryocontainer 10 facing the assembly side 19, compare the dashed lines in Figure 6.
- connecting lines 20 could also be routed from a single operating component 13, 14 in the direction of the vehicle frame 2, as can be the case, for example, with a heat exchanger that has a cryogenic fluid line leading to the engine in the direction of the engine, a feed line for a heat exchange medium and a Discharge line for a heat exchange medium, i.e. three connection lines 20 routed in the direction of the vehicle frame 2, compare Figures 2 and 3.
- an operating component 13, 14 it is not always necessary for an operating component 13, 14 to be in fluid communication with an engine of the vehicle 1 by means of a connecting line 20.
- a connecting line 20 for example, when the operating component 13, 14 is a filling coupling, which is guided directly through the lateral surface 16 into the cryocontainer 3, 4.
- the operating components 13, 14 do not necessarily have to be connected by means of a connecting line 15.
- all operating components 13, 14 belonging to a subsystem e.g. the filling system, can be arranged in one of the gussets ZI -Z4 and all operating components 13, 14 belonging to another subsystem, e.g no connecting line 15 is required.
- operating components 13, 14 of the subsystems can also be provided together in one of the gussets ZI - Z4, e.g. both operating components 13, 14 of the extraction system and the filling system can be present in one of the gussets, with further operating components of the extraction system being located in another the gusset can be arranged, for which purpose the operating components 13 , 14 of the extraction system can in turn be connected by means of a connecting line 15 . If a control unit is used to control other operating components 13, 14, it can be connected to operating components 13, 14 of the extraction system, filling system, conditioning system and/or the ventilation system.
- the figures also show that the two operating components 13 , 14 distributed around the circumference of the jacket surface 16 can be covered by a common cover 21 .
- the cover 21 can be designed to be removable and, if necessary, also cover the connecting line 15 or operating components 13, 14 in further gussets.
- FIGS. 10 and 11 show a further arrangement according to the invention, the first operating component 13 being arranged on the lateral surface 16 as described above and the second operating component 14 being arranged on the end cap 18 .
- the second operating component 14 is located at least partially, preferably completely, in a cap gusset Z5, which is enclosed between the end cap 18 and an imaginary cylinder Z that is as small as possible above this end cap 18.
- the axis of rotation of the imaginary cylinder Z generally coincides with an axis of rotation of the cryocontainer 3 or the end cap 18 .
- the second operating component 18 can also extend beyond this imaginary cylinder Z (FIG. 10), but usually does not protrude beyond the available installation space.
- the second operative component 14 resides entirely in a gusset enclosed between the end cap 18 and a smallest possible imaginary cuboid KQ ( Figure 11) above that end cap 18 .
- the second operating component 14 is arranged horizontally, for example, as shown in FIG. 11, but could also be arranged vertically or at an angle. Depending on the shape of the operating component 14 , it can also have no longitudinal extent and/or be adapted to the curvature of the end cap 18 .
- a connecting line 15 can also be provided between the first operating component 13 and the second operating component 14 in the embodiment in Figures 10 and 11, although this can also be omitted if, for example, connecting lines 20 are connected separately from each operating component 13, 14 in Direction of the vehicle frame 2 are performed.
- the connection line 20 or connection lines 20 can in particular be routed through the gussets that are enclosed between the end cap 18 and an imaginary cylinder or cuboid that is as small as possible.
- the imaginary cuboids of this embodiment are also arranged with horizontal or vertical sides.
- the operating components 13, 14 as well as the connecting line 20 and the connecting line 15, if present, are located completely within a small, imaginary cuboid above the cryocontainer 3, 4.
- a fluid line can be routed through the lateral surface 16 or one of the end caps 17, 18.
- a fluid line can be routed through one of the end caps 17, 18, and this fluid line can be routed to an operating component 13, 14 that is provided on the lateral surface 16 or that of the end cap 17, 18.
- an operating component 13, 14 a connecting line 20 or a connecting line 15 can optionally be continued as described above.
