Description

Title of the invention: Storage container for the intermediate storage of a thermoregulating agent

[0001] The present invention relates to a storage container for the intermediate storage of a thermoregulation agent and to a thermoregulation arrangement comprising such a storage container.

[0002] A battery of a vehicle can be cooled by immersion in a thermoregulation circuit using a thermoregulation liquid such as, for example, oil. In order to rid the thermoregulation agent of unwanted moisture, it is known to integrate, in the thermoregulation circuit, a drying device containing a desiccant, which device is capable of absorbing and storing the moisture present in the thermoregulation agent. In conventional thermoregulation circuits, such a drying device is, for example, included in a filtration device also present in the thermoregulation circuit and intended to separate dirt particles and the like from the thermoregulation agent.

[0003] The problem of the present invention therefore relates to new ways when developing solutions for improved drying of thermoregulation agents for a thermoregulation circuit, which is accompanied in particular by a reduction in the pressure loss in the thermoregulation agent.

[0004] This problem is solved by the subject matter of the independent claims. Preferred embodiments are the subject matter of the dependent claims.

[0005] The basic idea of the invention is therefore to provide the drying device explained above for the absorption of moisture from a thermoregulating agent in a storage container, intended to store the thermoregulating agent, arranged in a thermoregulating circuit. Such a storage container can store a significant amount of thermoregulating agent in order to compensate for volumetric expansions due to the temperature of the cooling system.

[0006] Since such a storage container requires more installation space than the filter device mentioned in the introduction, a drying device can be integrated into the storage container in such a way that it causes only a relatively low pressure loss in the temperature-regulating agent, which is in any case significantly lower than in the case of the arrangement implemented so far of the drying device in a filter device. Ultimately, the solution according to the invention described above makes it possible to achieve efficient drying of the temperature-regulating agent while limiting pressure losses.

[0007] According to the idea of the invention explained above, a storage container according to the invention for receiving a temperature control agent comprises a housing which surrounds a housing interior through which a temperature control agent can flow for the intermediate storage of the temperature control agent. The temperature control agent can in particular be an oil. As a temperature control agent or, as the case may be, oil for the temperature control circuit, a temperature control agent known to those skilled in the art under the designation "Mobil Therm Elite" can in particular be envisaged. If the storage container is arranged in a temperature control circuit, the temperature control agent accommodated in the housing interior can be directly used for its flow through the temperature control circuit. In this case, the housing interior is therefore also directly integrated into the temperature control circuit.In order to be able to integrate the storage container into the temperature control circuit, the storage container comprises a fluid inlet arranged on the housing and having an inlet opening, through which the temperature control agent can be introduced into the housing interior space. Furthermore, the storage container comprises a fluid outlet also arranged on the housing and having an outlet opening, through which the temperature control agent can be discharged from the housing interior space.

[0008] Furthermore, the storage container comprises a housing opening provided in the housing, through which opening the housing interior communicates fluidically with an external environment of the housing. This housing opening is thus provided in addition to the inlet opening and the outlet opening on the housing. Furthermore, the storage container comprises a closing element for closing the housing opening and, therefore, for being arranged in the housing opening. When the closing element is arranged in the housing opening, it closes the housing opening in a fluid-tight manner. According to the invention, a drying device, for absorbing moisture from the temperature-regulating agent present in the housing interior, is arranged on the closing element.

[0009] The drying device is arranged in the housing interior when the closure element is arranged in the housing opening. Thus, the drying device can dehumidify the temperature-regulating agent present in the housing interior or, as the case may be, flowing through the housing interior. Due to the relatively large volume of the housing interior - in particular compared to a filter device mentioned in the introduction - the pressure reduction caused by the drying device in the temperature-regulating agent is small.

[0010] In a preferred embodiment, the drying device is designed so that a flow of the thermoregulating agent can pass through it. This allows effective interaction between desiccants present in the drying device and the thermoregulating agent to be dehumidified.

[0011] Particularly preferably, the drying device may be partially housed in a housing provided in the inner housing space and in fluid communication with the outlet opening, such that the temperature-regulating agent flowing through the inner housing space must necessarily flow through the drying device before reaching the outlet opening. In this way, it is ensured that any temperature-regulating agent entering the storage container is subjected to dehumidification using the drying device. This results in particularly efficient drying of the temperature-regulating agent.

[0012] According to an advantageous improvement of the storage container according to the invention, the housing can be designed as an opening collar projecting from the housing inwards into the housing interior space and projecting from the inlet opening, the drying device can be partially inserted or slid into said collar. In this way, the drying device can be stably fixed in the housing interior space. This proves to be particularly advantageous when the storage container is placed, together with the drying device, in a motor vehicle, where it can be subjected to significant external forces, in particular in the form of shocks and mechanical impacts.

[0013] According to a further advantageous improvement, the closing element can be designed as a closing screw which can be screwed into the housing opening. This variant is of technically simple construction and therefore can be produced at low cost.

[0014] Particularly preferably, the drying device and the housing opening can be arranged in the housing interior or, as the case may be, on the housing and can be adapted to one another in such a way that the drying device, when the closure element is accommodated in the housing opening, protrudes therefrom into the housing interior. The drying device can then act on the temperature-regulating agent stored in the housing interior or, as the case may be, flowing through the housing interior. Since no additional installation space is required for the drying arrangement, this embodiment also proves to be space-saving.

[0015] In another preferred embodiment, the inlet opening and the housing opening may be arranged in a first housing wall of the housing. Furthermore, in this embodiment, the outlet opening is arranged in a second housing wall opposite the first housing wall of the housing. This ensures that a large portion of the thermoregulating agent present in the storage container, ideally all of the thermoregulating agent present in the internal space of housing, also participates in the flow in the thermoregulation circuit in which the storage container is placed.

[0016] In another preferred embodiment, the drying device is longitudinally shaped and extends from the first housing wall along a longitudinal direction to the second housing wall. A longitudinal extent of the drying device, measured along the longitudinal direction, is at least three times a transverse extent, measured perpendicular to the longitudinal extent direction.

[0017] Such a configuration requires that the thermoregulation agent circulating in a thermoregulation circuit passes through at least the volume of the internal housing space present between the two housing walls, which increases the probability of interaction with the desiccant present in the drying device.

[0018] Another embodiment of the storage container according to the invention, in which the first housing wall forms an upper face and the second housing wall forms a lower face of the housing in a preferred operating position of the storage container relative to the direction of gravity, has proven to be particularly advantageous. This ensures that air which is lighter than the temperature control medium and is therefore above the temperature control medium in the inner housing space cannot enter the temperature control circuit via the outlet.

[0019] According to another advantageous improvement, the drying device comprises a casing permeable to the thermoregulating agent, which surrounds a desiccant intended to absorb the moisture contained in the desiccant. A drying device thus produced is particularly simple to implement from a technical point of view and therefore inexpensive to manufacture. In particular, a granular desiccant may be used, particularly preferably a zeolite, a molecular sieve or a silica gel.

[0020] Particularly preferably, the envelope may be made of or comprise a flexible material. Particularly preferably, the envelope may be formed by a bag of fibrous material, in particular polyester, polyoxymethylene or polyamide, or by a fine mesh screen, in particular polyester, polyoxymethylene, polyamide or stainless steel.

[0021] Particularly preferably, the drying device is integral with the closing element. This facilitates the “handling” of the drying device in number with the closing screw by a worker.

[0022] According to another advantageous improvement, the drying device is produced in the form of a cartridge detachable from the closure element or, as the case may be, from the closure screw, comprising a cartridge housing permeable to the thermoregulating agent, the desiccant being arranged in said cartridge housing in such a way that so that it can come into contact with the temperature-regulating agent flowing around the drying device and thus absorb moisture from said temperature-regulating agent. The cartridge design allows the drying device to be replaced, for example, when the moisture-absorbing capacity of the desiccant is exhausted. In this case, the cartridge can be easily replaced with a replacement cartridge. To do this, it is sufficient to remove the closing element or, as the case may be, the closing screw from the housing opening and then detach the cartridge from the closing element or, as the case may be, the screw. Correspondingly, a replacement cartridge, containing unused pressurized agent, is attached to the closing element or, as the case may be, the closing screw and mounted on the housing together with the closing element or, as the case may be, the closing screw.

[0023] Particularly preferably, the drying device is detachably attached to the closure element using a bayonet closure. Such a bayonet closure is technically easy to implement and allows easy disassembly or assembly of the drying device, in particular when the latter is designed as a cartridge.

[0024] According to an advantageous improvement, the bayonet closure comprises a pre-tensioning element, in particular a pressure spring, for fixing the drying device to the closure element. The pre-tensioning element or, as the case may be, the pressure spring compresses the desiccant and prevents mutual friction within the desiccant. In this way, wear and the accumulation of dirt are counteracted.

[0025] The invention further relates to a temperature control arrangement for temperature control of a component. The temperature control arrangement according to the invention comprises a temperature control circuit in which a temperature control agent can circulate and circulates in particular during operation. The component to be temperature controlled is also arranged in this temperature control circuit, such that heat can be transferred between the component and the temperature control agent. Furthermore, the temperature control arrangement comprises a transport device, in particular in the form of a fluid or oil pump, for driving the temperature control agent into the temperature control circuit. According to the invention, a storage container presented above and thus according to the invention is arranged in the temperature control circuit for the intermediate storage of the temperature control agent.The advantages explained above of the storage container according to the invention therefore also apply to the thermoregulation arrangement according to the invention.

[0026] In a preferred embodiment of the thermoregulation arrangement according to the invention, the component to be thermoregulated is or comprises an electric battery, in particular of a motor vehicle, or a fuel cell system comprising at least one fuel cell. The fuel cell system may also be part of a motor vehicle or, alternatively, be a stationary fuel cell system.

[0027] Particularly preferably, the component to be thermoregulated can be arranged in the thermoregulation circuit in such a way that it can be directly surrounded by the thermoregulation agent. Such thermoregulation or, as the case may be, such cooling is known as "immersion cooling" and allows particularly effective thermoregulation or, as the case may be, cooling of said component.

[0028] Other important characteristics and advantages of the invention emerge from the subclaims, the diagrams and the description of the corresponding figures with the aid of the diagrams.

[0029] It goes without saying that the above-mentioned features and those which will be explained later can be used not only in the combination respectively indicated, but also in other combinations or alone, without departing from the scope of the present invention.

[0030] Preferred embodiments of the invention are shown in the diagrams and are explained in more detail in the following description, the same reference signs referring to identical or similar or functionally identical components.

[0031] The following are shown, respectively schematically:

[0032] [Fig-1]: an example of a storage container according to the invention, in a view in cut,

[0033] [Fig.2]: an example of a thermoregulation circuit according to the invention in a rough schematic representation, of the electrical diagram type.

[0034] [Fig. 1] illustrates, by way of example, a sectional representation of a storage container 1 according to the invention for the intermediate storage of a thermoregulating agent T. The storage container 1 comprises a housing 2 which surrounds an internal housing space 3 through which a flow of the thermoregulating agent T can pass and intended to receive the thermoregulating agent T. The storage container 1 further comprises a fluid inlet 5, arranged on the housing 2 and having an inlet opening 4, for introducing the thermoregulating agent T into the internal housing space 3. Furthermore, the storage container 1 comprises a fluid outlet 7, also arranged on the housing 2 and having an outlet opening 6, for discharging the thermoregulating agent T from the internal housing space 3.

[0035] In the scenario of the example of [Fig.l], the inlet opening 4 and the housing opening 8 are arranged in a first housing wall 15a of the housing 2. In contrast, the outlet opening 6 is arranged in a second housing wall 15b of the housing 2, opposite the first housing wall 15a.

[0036] Conveniently, in a preferred position of use of the storage container 1, the first housing wall 15a forms, relative to the direction G of gravity, an upper face 16 of the housing 2, while the second housing wall 15b forms a lower face 17 of the housing 2.

[0037] As shown in [Fig. 1], the temperature-regulating medium T is arranged, relative to gravity, in a lower region of the inner housing space 3. In the illustrated position of use of the storage container 1, air L can be arranged above the temperature-regulating medium T as a balancing volume in the inner housing space 3 (see [Fig. 1]). This air L can be compressed by the temperature-regulating medium T when the latter expands due to the temperature, for example. In order to ensure that the air L remains in the inner housing space 3 of the storage container 1 and cannot escape from the storage container 1 via the outlet 6, the outlet 6 is arranged in a lower face 17 of the housing 2. Correspondingly, as shown in [Fig.l], a tube 31 may protrude from the housing opening 5 or, as the case may be, from the inlet 4 into the housing interior 3, through which tube the temperature-regulating agent T is introduced into a region 32 of the housing interior 3 arranged below the air L and filled with the temperature-regulating agent T. This prevents the air L present at the top in the housing interior 3 from causing turbulence which could also be accompanied by an undesirable outflow of air L from the storage container 1.

[0038] According to [Fig.l], the storage container 1 comprises a housing opening 8 provided in the housing 2, through which the internal housing space 3 fluidically communicates with an external environment 9 of the housing 2. This housing opening 8 is provided in addition to the inlet opening 5 and the outlet opening 7 on the housing 2.

[0039] Furthermore, the storage container 1 comprises a closure element 10 for closing the housing opening 8 and which can be arranged or is arranged for this purpose in the housing opening 8. The closure element 10 can suitably be designed as a closure screw 14 which can be screwed into the housing opening 8. When the closure element 10 is arranged in the housing opening 8, it closes the housing opening 8 in a fluid-tight manner. A drying device 11 for absorbing moisture from the temperature-regulating agent T present in the inner space 3 of the housing and arriving at the drying device 11 is arranged on the closure element 10. In the example, the drying device 11 is integral of the closure element 10. When the closure element 10 is arranged in the housing opening 8, the drying device 11 is therefore arranged in the housing interior space 3. Preferably, the drying device 11 and the housing opening 8 are arranged and adapted to each other, as illustrated in the example scenario of [Fig.l], in such a way that the drying device 11 protrudes from the closure element 10 into the housing interior space 3 when the latter is housed in the housing opening 8.

[0040] As shown in [Fig.l], the drying device 11 is longitudinally designed and extends from the first housing wall 15a to the second housing wall 15b, along a longitudinal direction L which is preferably parallel to the direction G of gravity G. The drying device 11 may be partially housed in a housing 12 provided in the internal housing space 3 and fluidly communicating with the outlet opening 6. The housing 12 is designed such that, when the drying device 11 is housed in the housing 12, the thermoregulating agent T which flows through the internal housing space 3 must necessarily flow through the drying device 11 before reaching the outlet opening 6. Said housing 12 may be designed, as shown in [Fig.l], in the form of an opening collar protruding from the housing 2 inwards into the internal space 3 of the housing and protruding from the inlet opening 4, the drying device 11 being able to be partially inserted or slid into said collar.

[0041] As shown in [Fig. 1], the drying device 11 is designed as a cartridge 18 detachable from the closure element 10 or, as the case may be, from the closure screw 10, having a cartridge housing 19 permeable to the temperature-regulating agent T, in which a desiccant 26, for example a zeolite, a molecular sieve or a silica gel, is arranged in such a way that it can come into contact with the temperature-regulating agent T flowing around the drying device 11 and thus absorb moisture from the temperature-regulating agent T. The drying device 11 can be detachably attached to the closure element 10 by means of a bayonet closure 27. The bayonet closure 27 can in turn have an elastic prestressing element 33 in the form of a pressure spring 34, by means of which the drying device 11 can be attached to the closing element 10.

[0042] Preferably, the drying device 11 is designed to be able to be traversed by a flow of the thermoregulation agent. For this purpose, the drying device 11 may, in a variant not shown in the figures, have an envelope permeable to the thermoregulation agent T, which surrounds a granular desiccant 26, for example zeolites, molecular sieves or silica gels, in order to absorb the moisture contained in the thermoregulation agent T. The envelope may be made of a flexible material permeable to the thermoregulation agent. The envelope may be formed by a bag of fibrous material, for example polyester, polyoxymethylene or polyamide, or by a fine mesh sieve, for example polyester, polyoxymethylene, polyamide or stainless steel.

[0043] In the example of [Fig. 1], the housing 2 comprises two partition walls 30a, 30b which divide the internal space 3 of the housing into a first, a second and a third compartment 3a, 3b, 3c. The partition walls 30a, 30b both extend respectively from the upper face 6 towards the lower face 7 and therefore in a vertical direction V parallel to the direction of gravity G. Conveniently, the two partition walls 30a, 30b are formed in one piece on the housing 2 as illustrated, which means that the two partition walls 30a, 30b and the housing 2 are formed in one piece and in the same material.

[0044] In order to ensure that all of the thermoregulating agent T present in the storage container 1 is also available for flow through a thermoregulating circuit 21 (see [Fig. 2]) in which the storage container 1 is arranged, it is possible to provide in the two partition walls 30a, 30b, at a suitable location, respectively a passage 13 through which the first compartment 3a communicates fluidically with the second compartment 3b or, as the case may be, the second compartment 3b with the third compartment 3c. Similarly, as illustrated in [Fig. 1], a passage 13 can be provided in the second partition wall 30b, through which the air L present in the second compartment 3b can communicate fluidically with the air L present in the third compartment 3c.The two dividing walls 30a, 30b and the resulting subdivision of the internal housing space 3 into three compartments 3a, 3b, 3c separated from each other make it possible to combat unwanted movements of the thermoregulating agent T in the direction of an unwanted "back and forth" and against an air outlet L from the storage container 1 which could result therefrom.

[0045] [Fig. 2] shows, in the form of an electrical diagram, an example of a thermoregulation arrangement 20 according to the invention. The thermoregulation arrangement 20 comprises a thermoregulation circuit 21 in which the thermoregulation agent T circulates during operation of the thermoregulation arrangement 20 and in which the component 22 to be thermoregulated is arranged. In this way, heat can be transferred between said component 22 and the thermoregulation agent T. The component 22 can thus be thermoregulated, and thus in particular cooled.

[0046] For example, the component 22 to be thermoregulated may be an electric battery 24 of a battery-electric motor vehicle. But the component 22 to be thermoregulated may also be a fuel cell system comprising one or more fuel cells 29. In the scenario of the example, as indicated in [Fig. 2], the component 22 to be thermoregulated, i.e. the battery 24, is arranged in the circuit of thermoregulation 21 so as to be able to be directly surrounded by a flow of the thermoregulation agent T.

[0047] For this purpose, the battery 24 may have a battery housing 28 through which a flow of the thermoregulating agent T can pass and in which battery cells 29 to be thermoregulated are arranged. Thus, the thermoregulating agent T flowing through the battery housing 28 can absorb heat from the battery cells 29 when these are to be cooled or release it to the battery cells 29 when these are to be heated. Such thermoregulation or cooling is known as "immersion cooling".

[0048] Furthermore, the thermoregulation arrangement 20 comprises a transport device 23 for driving the thermoregulation agent T into the thermoregulation circuit 21. The transport device may for example be a fluid or oil pump.

[0049] As shown in [Fig. 2], the thermoregulation arrangement 20 further comprises a storage container 1 according to the invention, arranged in the thermoregulation circuit 21, for the intermediate storage of the thermoregulation agent T, as previously explained by way of example with the aid of [Fig. 2]. The storage container 1 can also act as a balancing container for making an additional quantity of thermoregulation agent T available to the thermoregulation circuit 21 when a certain quantity of thermoregulation agent has previously escaped from the thermoregulation circuit 21 due to a leak or for other reasons.

[0050] Furthermore, a heat exchanger 25 through which a flow of the thermoregulating agent T can flow can be arranged in the thermoregulating circuit 21. The heat exchanger 25 can be flowed through, in a fluidically separated manner with respect to the thermoregulating agent T, by a fluid F which can be thermally coupled to the thermoregulating agent T inside the heat exchanger 25. In this way, heat can be transferred from the thermoregulating agent T to the fluid F in order to cool the thermoregulating agent T or, conversely, heat can be transferred from the fluid F to the thermoregulating agent T when the thermoregulating agent T is to be heated.
