Description

Technical Field

[0001] The present invention relates to a heating system having the features of independent claim 1, a first method for generating a heating system having the features of independent claim 8, a second method for generating a heating system having the features of independent claim 10, and an electrochemical energy converter having the features of independent claim 14.

Background Art

[0002] When an electrochemical energy converter is used especially in remote areas, during the downtime of the provided water separator, it can happen that the medium, here water, freezes in the passages for the supply or discharge of the medium. For this reason, heating elements are provided nowadays, and the heating elements are manufactured, for example, from electrically conductive plastics. Electrically conductive plastics are nowadays injection molded and cured in a pre-temperature-controlled mold.

[0003] During the use of these heating elements, deterioration of heat transfer often occurs. This is because the heating elements do not correspond to the shape provided in the water separator or shrink during the curing process. Therefore, a gap is created here between the heating element and the housing, and this gap prevents the medium in the supply passage or discharge passage from being thawed efficiently or causes elements provided along the passage, such as valves, sensors or the like, not to be preheated.

[0004] This becomes a problem especially during the use of the water separator. This is because in this case, the elements incorporated along the passage may be damaged or their lifespan may be reduced. Additionally, the contained medium cannot be supplied or discharged quickly enough, resulting in an obstacle to the process.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The present invention proposes a heating system having the features of independent claim 1, a first method for producing a heating system having the features of independent claim 8, a second method for producing a heating system having the features of independent claim 10, and an electrochemical energy converter having the features of independent claim 14. Further features and details of the present invention can be found in the dependent claims, specification and drawings. It is obvious that the features and details described in relation to the heating system according to the present invention also apply in relation to the first method according to the present invention, and / or the second method according to the present invention, and / or the electrochemical energy converter according to the present invention, and vice versa, and as a result, they are always mutually referenced or can be referenced with respect to disclosures of individual embodiments of the invention. [Means for solving the problem]

[0006] A first aspect of the present invention is a heating system for indirectly heating a medium, particularly water, in at least one medium passage or medium container, comprising a medium container for containing the medium to be heated. In this case, the medium container has a cavity extending at least partially around the medium container. Additionally or alternatively, the medium container has at least one medium passage for discharging and / or supplying the medium, and a cavity extending at least partially parallel to the medium passage and / or at least partially around the medium passage. Additionally, the heating system comprises a heating element for heating the medium, having a heating section and a mounting section, wherein the heating section is located in the cavity of the medium container and / or in the cavity of at least one medium passage of the medium container, and the mounting section for mounting the heating element comprises a heating element provided in the medium container such that the cavity is closed.

[0007] In this case, the heating element has at least two electrical contacts, the at least two electrical contacts are located within the heating section and are connectable to an external current source in the mounting section, and within the heating section, the at least two electrical contacts are surrounded by an electrically conductive elastomer.

[0008] In this context, a cavity is understood to be a containment or hollow chamber provided within the medium container. Advantageous for heating the medium is when the wall thickness of the medium container is as minimal as possible to ensure improved heat transfer between the cavity and the medium to be heated. In this case, a wall thickness in the range of 3mm to 20mm, preferably 4mm to 15mm, and more preferably 5mm to 10mm, has been found to be particularly advantageous.

[0009] The cavity may be flat, concave, or convex. In this case, the cavity may have a horseshoe, U-shape, or L-shape in cross-section, and as a result, the passage is at least partially surrounded by the cavity. This ensures that during use, the medium present in the passage is heated and, consequently, thawed, or can be thawed, through the periphery of the passage or through a portion of the periphery of the passage. Generally, heating or thawing of the medium is ensured when the cavity surrounds at least 50%, preferably at least 60%, preferably at least 70%, of the passage in cross-section. Local heating of the medium within the passage is also possible.

[0010] At least two electrical contacts can also be housed within the cavity in this case, so that heat is rapidly distributed where it is most needed. It is particularly advantageous in this case if an electrically conductive elastomer constitutes the cavity in the heating section of the heating element. This has the advantage of leaving relatively little air in the cavity, resulting in optimized heat transfer to the medium.

[0011] Within the scope of the present invention, it may be advantageous that the medium container is an electrochemical energy converter, particularly a water separator in a fuel cell system, and that the medium supplied and / or discharged through the medium passage is water.

[0012] This heating system is particularly well-suited for water separators in electrochemical energy converters, as these are exposed to various temperature fluctuations during continuous use. Here, the medium present in the medium passage supplying or discharging the medium from the medium container—in the case of a water separator, water—can be quickly and easily heated and thawed. This improves the lifespan of surrounding components while ensuring optimized operation of the electrochemical energy converter.

[0013] Within the scope of the present invention, the outer contour of the heating section of the heating element may correspond to the inner contour of the cavity of the medium container and / or the inner contour of the cavity of at least one medium passage of the medium container.

[0014] The accuracy of the heating section's fit is ensured when the inner contour of the cavity of the medium container and / or the inner contour of the cavity of at least one medium passage of the medium container corresponds to the outer contour of the heating section of the heating element. This reduces the amount of air in each cavity, or eliminates any gaps between the heating section and the medium container. As a result, optimized heat transfer exists from the heating element to the medium passage and / or medium container, because there is no longer an air layer within the cavity that provides insulation.

[0015] Within the scope of the present invention, a medium container and / or mounting section may have at least one injection passage, the injection passage extending from the outer surface into the cavity, and at least one injection passage designed for the injection of an electrically conductive elastomer. An injection mold for manufacturing a heating element may also have an injection passage.

[0016] The electrically conductive elastomer is injected through injection channels provided on the outer surface of the cavity or mounting section. This is particularly advantageous because the precision of the fitting of the heating element within the cavity can be ensured by the injection of the elastomer. Therefore, the presence of air between the heating section and the medium container is prevented. This allows heat transfer to be equalized and optimized across the surface of the cavity. At the same time, the manufacturing of the heating element is simplified.

[0017] Furthermore, injection allows for the use of any cavity shape without creating abrupt changes or inconsistencies in heat transfer.

[0018] This allows the cavity to have a shape that would be impossible if the heating element were simply pushed into the cavity. For example, the cavity can now have an undercut, which allows it to optimally conform to the shape of the medium passage. This, therefore, enables the design of the cavity to conform to the area required for thawing or heating the medium within the medium passage.

[0019] Furthermore, the electrically conductive elastomer may contain an electrically conductive filler in a proportion of 5% to 50%, preferably 7% to 40%, and more preferably 10% to 35%.

[0020] The use of an elastomer containing an electrically conductive filler results in an optimal generation of Joule heat within the heating section when an electric current is applied to the electrical contact. Accordingly, the proportion of the electrically conductive filler can be selected according to the desired heat to be generated.

[0021] The elastomer can be rubber, fluororubber, silicone, fluorosilicone, thermoplastic elastomer, and acrylate rubber.

[0022] The electrically conductive filler can also be at least one of the following substances, namely, - carbon black and / or - graphite and / or - metal powder and / or - metal fiber and / or - carbon nanotubes It is also possible to be at least one type.

[0023] These electrically conductive fillers are particularly well-suited for being mixed with the elastomer. These electrically conductive fillers not only generate the required conductivity but also generate a uniform distribution of Joule heat within the heating section of the heating element.

[0024] ​​​​​​​​​​​​​By "coupled tightly to the medium" is here understood welding, fitting, clipping or gluing of the attachment section of the heating element to the container.

[0028] A second aspect of the invention is a method according to a first invention for generating a heating system according to a first aspect of the invention, comprising the following steps, namely: - providing a medium container having a cavity and / or at least one medium passage of a medium container; - attaching the attachment section of the heating element to the medium container and closing the cavity of the medium container and / or the cavity of at least one medium passage of the medium container; - introducing at least two electrical contacts into the cavity of the medium container and / or the cavity of at least one medium passage of the medium container via the attachment section and making the electrical contacts connectable in contact to an external current source; - providing an electrically conductive elastomer in the cavity of the medium container and / or the cavity of at least one medium passage of the medium container; which is a method for generating a heating system.

[0029] In this case, the order of the steps is not fixed. Here, for example, it would also be possible to first provide the elastomer, then close the cavity of the heating element by means of the attachment section and subsequently introduce the electrical contacts.

[0030] Whether the electrically conductive elastomer is provided after attaching the attachment section or before attaching the attachment section, this electrically conductive material is in a liquid state. This ensures that the elastomer can easily adopt the shape of the cavity.

[0031] Furthermore, within the scope of the present invention, an electrically conductive elastomer may be supplied, particularly injected, into the cavity of the medium container and / or the cavity of the at least one medium passage of the medium container, either through or directly via at least one injection passage of the medium container and / or mounting section.

[0032] This ensures that the cavity is filled quickly and reliably. The elastomer can reliably take on the shape of the cavity. If the elastomer shrinks slightly when it cools or solidifies, additional material may be supplied through the injection channel.

[0033] A third aspect of the present invention is a second method according to the present invention for generating a heating system according to the first aspect of the present invention, the following steps: - A step of preparing a media container having a cavity and / or a media container having at least one media passage having a cavity, - A step of preparing an injection mold having a hollow chamber for generating a heating element, wherein the hollow chamber corresponds to the cavity of a medium container and / or the cavity of at least one medium passage of the medium container, - The step of closing the hollow chamber of the injection molding die with the mounting section for the heating element, - The steps include introducing at least two electrical contacts into a hollow chamber via a mounting section, and enabling the electrical contacts to be contact-connected to an external current source, - A step of supplying an electrically conductive elastomer into a hollow chamber, - A step of curing the elastomer in an injection mold, - The step of releasing the heating element from the injection mold, - The step of inserting the heating element into the cavity so that the heating section of the heating element fills the cavity, - Steps include attaching the mounting section to the media housing, This is a method for generating a heating system having [a certain characteristic].

[0034] To achieve this, first, an injection mold corresponding to the shape of the cavity must be created. Depending on the elastomer used and its shrinkage behavior, the injection mold may be designed to be larger than necessary, so that the shape of the elastomer after shrinkage corresponds to the shape and size of the cavity.

[0035] Furthermore, it is conceivable to supply, in particular inject, an electrically conductive elastomer into the injection mold either through at least one injection passage in the mounting section or directly.

[0036] This allows for the optimal generation of the heating section's shape, resulting in all possible curves or corners of the heating section being filled with elastomer.

[0037] Within the scope of the present invention, in both the first and second methods, it may be advantageous to cure the supplied electrically conductive elastomer by supplying heat. In this case, this heat can be supplied, in particular, by energizing an electrical contact with an external power source.

[0038] This allows for internal curing, thereby reducing the curing time. Simultaneously, it enables testing of the heating element's functionality. Furthermore, it allows verification of whether the electrically conductive filler is evenly distributed within the elastomer.

[0039] In this case, the applied voltage of the load powered by an electrochemical energy converter can be used. The voltage source can supply 12V to 24V. However, it is also possible to use a voltage source that can supply voltages from 5V to 220V.

[0040] Within the scope of the present invention, the mounting section of the heating element can be attached to the medium container in a media-tight, shape-bonded and / or material-bonded manner, particularly by welding, bonding, fitting, or clipping.

[0041] This ensures, on the one hand, that the cavity is medium-tight for the injection process, and as a result, that the elastomer does not leak, and on the other hand, that the heating element cannot separate from the cavity during operation.

[0042] A fourth aspect of the present invention is an electrochemical energy converter, particularly a fuel cell or fuel cell system, comprising a heating system manufactured according to the first aspect of the present invention and according to the second or third aspect of the present invention.

[0043] The advantages described in detail with respect to one aspect of the present invention also apply to other aspects of the present invention.

[0044] Further advantages, features, and details of the present invention can be found in the following description. Several embodiments of the present invention will be described in detail below with reference to the drawings. The features mentioned in the claims and specification may be essential to the invention, either individually or in any combination. The present invention is illustrated in the following figures. [Brief explanation of the drawing]

[0045] [Figure 1] This is a schematic diagram of the first heating system according to the present invention. [Figure 2] This is a schematic diagram of the first heating system according to the present invention in cross-section AA. [Figure 3] This is a schematic diagram of a second heating system according to the present invention. [Figure 4] This is a schematic diagram of the first method according to the present invention. [Figure 5] This is a schematic diagram of a second method according to the present invention. [Figure 6]This is a schematic diagram of an electrochemical energy converter. [Modes for carrying out the invention]

[0046] Figures 1 and 2 show a heating system 10 that indirectly heats a medium 12 in at least one medium passage 14. In this case, the heating system 10 comprises a medium container 16 that contains the medium 12 to be heated, and a heating element 20 that heats the medium 12. The medium container 16 is here a water separator 32 of an electrochemical energy converter 34, and therefore the medium 12 is water.

[0047] In this case, the medium container 16 has at least one medium passage 14 for discharging and / or supplying the medium 12, and a cavity 18. The cavity 18 extends in this case parallel to the medium passage 14 in at least some sections and, based on the horseshoe shape of the cavity 18, at least partially surrounds the medium passage 14.

[0048] The heating element 20 has a heating section 22 and a mounting section 24. In this case, the heating section 22 is located inside the cavity 18. The mounting section 24 for mounting (120) the heating element 20 is provided in the medium container 16 such that the cavity 18 is closed.

[0049] In this case, the heating element 20 has at least two electrical contacts 26, which are located within the heating section 22 and can be contact-connected by an external current source 28 in the mounting section 24. In this case, within the heating section 22, at least two electrical contacts 26 are surrounded by an electrically conductive elastomer 30. In this case, the outer contour 38 of the heating section 22 of the heating element 20, i.e., the outer contour 38 of the elastomer including at least two electrical contacts 26, corresponds to the inner contour 40 of the cavity 18 of the medium container 16. This prevents an air gap from existing between the heating section 22 and the medium container 16, and as a result, heat is optimally transferred from the heating element 20 into the housing wall of the medium container 16, thereby keeping the medium passage 14 free of ice or thawing any frozen medium 12.

[0050] Figure 3 shows a second embodiment of the heating system. In this embodiment, a medium container 16 is provided having a cavity 18 that extends at least partially around the medium container 16. In this embodiment as well, a heating element 20 for heating the medium 12 is provided having a heating section 22 and a mounting section 24. In this embodiment, the heating section 22 is located within the cavity 18 of the medium container 16, and the mounting section 24 for mounting the heating element 20 is provided in the medium container 16 such that the cavity 18 is closed. Here again, the heating element 20 has at least two electrical contacts 26, at least two of which are located within the heating section 22 and are contact-connectable by an external current source 28 in the mounting section 24, and at least two of the electrical contacts 26 within the heating section 22 are surrounded by an electrically conductive elastomer 30.

[0051] As shown in Figures 4 and 5, the elastomer is supplied, or can be supplied, in a liquid state, and therefore an injection passage 42 is provided. In the embodiment of the heating system 10 shown in Figures 1 and 2, the injection passage 42 is located within the mounting section 24. In one embodiment not shown, the injection passage 42 may be located within the medium container 16. The injection passage 42 extends from the outer surface 44 of the mounting section 24 into the cavity 18, and at least one injection passage 42 is designed for the injection of an electrically conductive elastomer 30.

[0052] In the embodiments shown in Figures 1 to 6, metal fibers are added to the electrically conductive elastomer 30 at a ratio of 30%.

[0053] To ensure electrical conductivity, it is desirable to provide an electrically conductive filler in a proportion of 5% to 50%, preferably 7% to 40%, and more preferably 10% to 35%. These electrically conductive fillers may, in this case, be carbon black and / or graphite and / or metal powders and / or carbon nanotubes.

[0054] In the illustrated heating system 10, the mounting section 24 is tightly bonded to the medium container 16. In this case, the mounting section 24 is welded to the medium container 16, and thus bonded to the medium container 16 by material.

[0055] Figure 4 shows a first method 100 for generating the heating system 10 shown in Figures 1 and 2, comprising the following steps: - Step 110 involves preparing a medium container 16 having a cavity 18, - Step 130 involves attaching the mounting section 24 of the heating element 20 to the medium container 16 120 and closing the cavity 18, - Step 140 involves introducing at least two electrical contacts into the cavity 18 via the mounting section 24, so that the electrical contacts can be contact-connected to an external current source 28. - Step 150 involves providing an electrically conductive elastomer 30 into the cavity 18, A method having this is shown.

[0056] In this case, the electrically conductive elastomer 30 is supplied 150 or injected through at least one injection passage 42 of the medium container 16. In another embodiment, the injection passage 42 may be located within the mounting section 24. It is also possible to supply 150 (inject) it directly into the cavity 18, and then close 130 the cavity 18 with the mounting section 24.

[0057] Figure 5 shows a second method 200 according to the present invention for generating the heating system 10 shown in Figures 1 and 2. In this case, first, a heating element 20 is manufactured, which can then be subsequently inserted into the cavity 18. This method 200 is comprised of the following steps, namely: - Step 210 involves preparing a medium container 16 having a cavity 18, - Step 210 is to prepare an injection mold 46 having a hollow chamber for generating a heating element 20, wherein the hollow chamber corresponds to a cavity 18, - Step 220 involves closing the hollow chamber of the injection mold 46 with the mounting section 24 of the heating element 20, - Step 230 involves introducing at least two electrical contacts 26 into the hollow chamber via mounting section 24, and enabling at least two electrical contacts 26 to be contact-connected to an external current source 28, - Step 240 involves providing an electrically conductive elastomer 30 into the hollow chamber, - Step 280 involves curing the elastomer 30 in the injection mold 46, - Step 250 involves releasing the heating element 20 from the injection mold 46, - Step 260 involves inserting the heating element 20 into the cavity 18 so that the heating section 22 of the heating element 20 fills the cavity 18, - Step 270 involves attaching the mounting section 24 to the media housing, It has.

[0058] In this method 200, at least one injection passage 42 may be provided within the injection mold 46. However, even here, it is possible to directly supply, in particular inject, an elastomer containing an electrically conductive filler into the injection mold 46.

[0059] In both the first method 100 and the second method 200, the supplied electrically conductive elastomer 30 is cured by the supply of heat. For this purpose, heat is supplied by energizing the electrical contact 26 with an external power source.

[0060] In this case, in both the first method 100 and the second method 200, the mounting section 24 of the heating element 20 is materially bonded to the medium container 16 in a medium-tight manner. Here, the mounting section 24 is welded to the medium container 16.

[0061] Figure 6 shows an electrochemical energy converter 34 in the form of a fuel cell system 36 equipped with the heating system 10 shown in Figures 1 and 2. [Explanation of symbols]
