Abstract

The invention relates to a method for producing an air-conditioned ceiling or wall, comprising the provision of a surface heat exchanger which has a, in particular metallic, carrier plate to which a pipe system for conducting a medium is fixed, further comprising the, in particular lateral, fastening of the surface heat exchanger to at least one ceiling-side or wall-side holding profile, characterized in that the fastening, in particular exclusively, takes place by at least one adhesive element which is or will be glued to both the carrier plate and the holding profile.

Description

The present invention relates firstly to a method for producing an air-conditioned ceiling or air-conditioned wall.

Such methods typically involve attaching a surface heat exchanger to the corresponding building surface. The heat exchanger usually comprises at least one (metallic) carrier plate to which a pipe system is attached, through which a cooled or heated medium is later conducted (e.g. water).

From the DE 10 2012 014 827 A1 The applicant is already aware of such a method, which describes a method in which a construction made of C-profiles is first mounted on the ceiling of a building, which run parallel and are spaced apart from one another by a distance that is slightly larger than the external dimensions of the support plate of the surface heat exchanger. The surface heat exchangers are pre-attached to the metal profiles, for which purpose separate hook elements are typically provided. These hook elements initially apply the entire load for holding the surface heat exchangers to the metal profiles.

After pre-fastening with the help of the hook elements, the support plates of the surface heat exchangers protrude slightly downwards with their underside compared to the underside of the metal profiles.

Subsequently, plasterboards are attached to the metal profiles (e.g. screwed), whereby the top of the plasterboards is brought into contact with the underside of the carrier plates or surface heat exchangers in such a way that when the plasterboards are screwed in place, the carrier plate (and thus the entire surface heat exchanger) is finally slightly raised, so that in the final assembled state, the underside of the carrier plate is essentially flush with the underside of the metal profiles and the hook elements are essentially no longer loaded.

Even if the method described in the aforementioned prior art can still be used advantageously in principle, there is a constant effort to find a simpler, possibly more resource-efficient way of producing a climate-controlled ceiling or climate-controlled wall.

The present invention solves this problem with the features of claim 1 and is therefore particularly characterized in that the surface heat exchanger is attached to the holding profile by an adhesive element which is or will be glued to both the carrier plate and the holding profile (or by several corresponding adhesive elements).

In other words, the idea of the invention essentially consists in carrying out the pre-assembly or fastening exclusively with the aid of adhesive elements (or at least supporting the pre-assembly with the adhesive elements), whereby the adhesive elements, at least in the pre-assembled state, take up the entire load or part of the load or at least ensure fixation, so that in particular the hook elements known from the prior art are supported or even made superfluous.

In other words, the surface heat exchanger is glued to one or more retaining profiles.

In particular, this allows “two birds to be killed with one stone”, since the adhesive element is typically thermally conductive and thus an additional thermal connection of the holding profile to the surface heat exchanger can be achieved.

From the above-mentioned state of the art, it was previously known (and necessary) to provide separate strip elements in the form of carbon strips for the thermal connection of the surface heat exchangers to the profiles, which, however, were exclusively glued either to the heat exchanger or to the profile, and were only activated by the fastening of the plasterboard with regard to their function as a thermal bridge between the surface heat exchanger and the profile.

The invention now recognizes that it is possible to combine the functions of the two elements, namely that of a thermally activating strip on the one hand and that of the hook element enabling pre-assembly on the other hand, in just one component.

In addition, a thermal connection of the retaining profile can now be made before a cover plate is attached or even without a cover plate being installed at all.

The adhesive element can preferably be an adhesive strip or an adhesive tape, whereby these terms are essentially synonymous in the sense of the present application. In the non-bonded state, an adhesive strip or an adhesive tape can be rolled up on a roll-like holder or something similar (but this does not have to be the case).

The adhesive element is particularly designed to be flexible.

Flexural slackness is particularly evident in the longitudinal direction of the adhesive element. The length of an adhesive strip or adhesive tape typically exceeds its width by several times.

If the adhesive element is an adhesive strip, it can be provided either without a carrier (so-called “transfer adhesive tape”) or not without a carrier.

The adhesive strip can in particular have one or more layers. In particular, an adhesive layer can be provided and at least one further layer, which, for example, has thermally conductive properties.

This other layer can then be formed, for example, as a metal layer or as a metal foil or something similar.

Such an adhesive strip or such an adhesive tape can have at least one protective layer or protective film, which is removed before the fastening according to the invention. This layer can initially cover both an adhesive surface for the carrier plate and one for the holding profile. Preferably, however, it only covers an adhesive layer for the holding profile, in particular if the adhesive strip or the adhesive tape is glued directly to the carrier plate (conversely, of course, only one protective layer can be provided for the carrier plate if the adhesive strip is glued directly to the holding profile).

Typically, the adhesive element is glued with one long side to the carrier plate and with the other long side to the holding profile.

According to its longitudinal orientation, the adhesive element can therefore essentially extend over the (longitudinal) gap between the carrier plate and the holding profile and bridge or cover it.

For this purpose, the adhesive element has in particular an adhesive surface for the carrier plate and an adhesive surface for the holding profile, which preferably even merge into one another. In this case, they would be arranged on the same side of the adhesive element. Alternatively, it is also possible to arrange the two adhesive surfaces on opposite sides of the adhesive element.

The gap typically formed between the carrier plate and the holding profile can be assigned to the middle part of a common adhesive surface, which part in this case only covers the gap and does not lie against the material of the carrier plate or the material of the holding profile.

According to the invention, the fastening is carried out by the adhesive element. This means, according to the most preferred embodiment, that the fastening is carried out completely by the adhesive element and the adhesive element therefore bears the entire weight of the surface heat exchanger, at least on the side of the surface heat exchanger assigned to it. In particular, the mechanical hook elements or similar mentioned in the prior art are superfluous in this case and are generally not present.

The adhesive element can replace such mechanical fastening elements in particular, since a cover plate is typically subsequently fastened under the carrier plate and holding profile, which then assumes the entire load of the surface heat exchanger in the long term, so that the adhesive element is subsequently relieved and can preferably serve as a thermal bridge between the carrier plate and the holding profile.

The fastening of the surface heat exchanger to the holding profile according to the invention is therefore typically only a temporary fastening (which in the prior art was carried out - exclusively - by mechanical holding elements such as hooks).

In its broadest sense, the invention also initially includes the fact that the adhesive element only participates in the fastening in the sense that the fastening is carried out by an adhesive element and other elements. In this sense, the adhesive element can, for example, bear part of the load or fix the position of the surface heat exchanger relative to the holding profile. Such a fixation can already improve a process without the adhesive element having to bear any load at all.

If the adhesive element is an adhesive tape or an adhesive strip, it typically has at least one adhesive surface on at least one side. In particular, however, it can also be a double-sided adhesive tape or a double-sided adhesive strip.

According to the invention, the invention preferably provides a method step in which the fastening of the surface heat exchanger to the holding profile is carried out exclusively by one or more adhesive elements.

This wording does not exclude the possibility that a long-term attachment may be made later by an additional retaining plate, which is screwed, for example, to the retaining profile.

At this point, it should be noted that instead of a single adhesive element, several adhesive elements could of course also be provided, for example in a strip-shaped arrangement.

Even if, according to the invention, strip-shaped adhesive elements are preferably to be provided, adhesive elements of other types or shapes are not excluded in any case in the broadest version of the invention, for example bulky adhesive masses or adhesive balls or the like, as well as in particular solidified, initially liquid or highly viscous adhesive masses, which are glued both to the carrier plate and to the holding profile.

The fastening according to the invention relates to fastenings of a surface heat exchanger to at least one holding profile.

Depending on the application, the retaining profile is arranged on the ceiling side (or on the wall side, for example in the case of wall heating).

In this sense, the method according to the invention can comprise a step which comprises attaching at least one retaining profile (or several retaining profiles) to a room ceiling (or room wall).

Typically, the surface heat exchanger is arranged between at least two support profiles.

In this case, the surface heat exchanger can be arranged or attached to both holding profiles with at least one adhesive element each.

The holding profiles are typically arranged parallel.

The holding profiles are usually so-called “C-profiles”.

The corresponding retaining profiles are preferably made of metal.

In principle, the invention also includes profiles made of other materials, for example wood or similar.

The holding profiles are essentially beam-like and/or essentially aligned or formed along a longitudinal orientation.

In the fastening according to the invention (which, as described above, is typically a type of pre-fastening), the surface heat exchangers or their support plates typically protrude slightly downwards relative to the profiles and are later raised to a flush level during the fastening of a support plate (e.g. made of plasterboard).

In contrast to the cover plates (for example made of plasterboard), which are attached to the support profiles from below, the fastening of the surface heat exchanger to the support profile or profiles according to the invention typically takes place more laterally. In other words, during (pre-)assembly, the surface heat exchanger is first brought to a height that corresponds approximately to that of the support profile (with the aforementioned slight overhang downwards) and then typically attached to the side of or next to the support profile. In particular, a gap that arises between the support profile and the surface heat exchanger for tolerance reasons can be bridged by the adhesive element.

In other words, the surface heat exchanger typically extends in a plane in which the retaining profile(s) are also essentially arranged.

The surface heat exchanger according to the invention comprises at least one carrier plate (which is typically made of metal, such as aluminum or stainless steel). The carrier plate can either be present as a single piece or as part of a holding cassette or even be inserted into a holding cassette.

The surface heat exchanger also includes a pipe system arranged on the carrier plate. When forming an air-conditioned ceiling, the pipe system is typically arranged above the carrier plate, while when forming an air-conditioned wall, it is usually arranged behind the carrier plate in relation to the interior of the room.

The pipe system is typically a system of pipe sections made of metal, in particular copper or titanium or aluminum or similar. The pipe system can be in its most common form as a meander pipe or harp-shaped or in another suitable shape.

In particular, it has a plurality of parallel straight pipe sections, which are further preferably arranged parallel and/or orthogonally in the assembled state on the holding profiles.

In particular, straight sections of the pipe system can have a circular shape or a D-shaped cross-section, for example, and are usually used to conduct an air-conditioning medium, preferably water. In other words, heated water is typically conducted through the pipe system for ceiling or wall heating, whereas cooled or unheated water is used to create a cooling effect.

The pipe system or individual sections of the pipe system are usually fixed to the carrier plate, for example with the help of heat conducting plates or heat conducting foils that span the pipe sections and sandwich the pipe section between themselves and the carrier plate. Such heat conducting plates can even provide the adhesive elements in some embodiments.

In other embodiments, however, the pipe system sections can also be attached to the carrier plate in a different way, e.g. welded or with the help of holding elements or the like arranged under the pipe system (i.e. between the pipe system and the carrier plate).

To create an air-conditioned ceiling or wall, typically more than one surface heat exchanger and more than one support profile are used.

As already described above, a surface heat exchanger is usually arranged between two support profiles. In principle, however, constructions could also be provided in which two or more surface heat exchangers are arranged between two support profiles, which are in particular attached to one another or similar.

The invention also encompasses the possibility that an adhesive element is provided only on one side of the heat exchanger, so that the heat exchanger is only glued to a holding profile on one side and to another holding profile on the other side, for example via mechanical hook elements or the like.

According to a particularly advantageous embodiment of the invention, the adhesive element is designed to be thermally conductive. This means in particular that the thermal conductivity λ of the adhesive element (or of a conductive section or part of the adhesive element) has a value of more than 1 W/(mK), in particular of more than 10 W/(mK), further in particular of more than 100 W/(mK).

The decisive factor in this embodiment is that the adhesive element can simultaneously provide a thermal bridge between the carrier plate and/or surface heat exchanger and the holding profile to which it is glued.

In this way, the surface heat exchanger area is essentially widened by thermally activating the retaining profiles arranged between the surface heat exchangers.

The element which is responsible for fastening or fixing or pre-assembling the surface heat exchanger to the support profile (partially or completely) simultaneously takes on the function of the thermal bridge and the function of thermally overcoming the gap between the surface heat exchanger and the support profile (which gap typically occurs automatically due to the design, in particular due to tolerances which must be observed).

A particularly good thermal conduction of the adhesive element can be achieved if, according to a further advantageous embodiment of the invention, it is designed as a metal strip or metal foil strip.

The adhesive element is essentially strip- or band-shaped and has a layer of metal. If this layer is sufficiently thin, it is also referred to as metal foil.

It is advantageous to design the adhesive element as a metal foil strip. However, the invention can also be implemented using other combinations, e.g. if an adhesive is used in conjunction with a metal paste or the like.

If the adhesive element comprises a metal foil, this typically has a thickness of between 0.01 mm and 0.5 mm, typically between 0.09 mm and 0.2 mm, usually in the range of about 0.1 mm.

The metal strip or metal foil strip is in particular designed as an aluminum (foil) strip or as a copper (foil) strip or contains another suitable metal.

In principle, it is conceivable that the adhesive layer is integrated into the tape or strip.

Alternatively, it is also possible to use a metal foil with a double-sided adhesive tape in the process. Both together then represent the adhesive element in the sense of the invention.

Preferably, the adhesive element is not designed as a carbon strip or is carbon-free.

According to a particularly advantageous embodiment of the invention, it is provided that the surface heat exchanger is manufactured and/or provided at a first location. In this case, it is then transported (in particular delivered or shipped) to a second location, the installation location, at which the climate ceiling or climate wall is to be created or installed. The retaining profiles can already be provided at the installation location or can be delivered to it together with the surface heat exchanger(s) or from a third location.

It is particularly advantageous that the adhesive element can be attached to the surface heat exchanger at the first location, where it has an adhesive surface or mounting adhesive surface, which is to be glued to the holding profile later, namely at the installation location. For transport purposes, this can be provided with a removable protective layer. This can be a protective film, for example, as is known from double-sided adhesive tape.

This protective layer then prevents the mounting adhesive surface from sticking to other objects during transport, for example other supplied surface heat exchangers. At the installation site, this protective layer can then be removed or peeled off, preferably manually by the fitter, and the surface heat exchanger can be glued to a ceiling-side support profile using the exposed mounting adhesive surface.

In particular, it is provided that the adhesive element is fixed, i.e. glued, to the surface heat exchanger at the first location (which is typically the headquarters of the surface heat exchanger manufacturer). For this purpose, the adhesive element can provide a second, in particular parallel adhesive surface, which (since it is then already glued to the surface heat exchanger), in contrast to the assembly adhesive surface, no longer needs to be covered for transport. The two adhesive surfaces can in particular merge into one another, and, for example, a protrusion of the adhesive element can be provided with the protective film after gluing to the surface heat exchanger at the first location.

According to an alternative method, the adhesive element can (first) be attached, namely glued, to the holding profile at a second location, in particular at the installation location. The protrusion of the adhesive element created in this way can then later be used to attach or glue the surface heat exchanger to the holding profile. In terms of sequence, this is therefore a process that is exactly the opposite of that described above: In this process, the adhesive element is first attached to the holding profile and then to the surface heat exchanger, whereas this was exactly the other way around in the process described above.

In this alternative method, the overhang can also be provided with a protective layer, for example in the event that the retaining profiles are also to be brought to the installation site from a third location (and are to be prepared beforehand), or in the event that the adhesive element is attached to the retaining profile already mounted on the ceiling or wall long before the surface heat exchangers are even installed or delivered (in this case, to ensure that the otherwise uncovered adhesive surface does not become dirty).

For the avoidance of doubt: According to this alternative method, the adhesive element can be attached to the retaining profile at the installation location or at a third location, but it is crucial that the surface heat exchanger is attached to the retaining profile (using the adhesive element) only subsequently or later.

According to the most preferred embodiment of the present invention, it is provided that a construction plate or cover plate is arranged (beneath the holding profile) and below the carrier plate. This is typically attached to the holding profile, preferably screwed. In this case, it is particularly provided that the surface heat exchanger already pre-assembled via the adhesive element is slightly raised (and the adhesive element is thus relieved). The adhesive element can then typically "concentrate" on its properties as a thermal bridge and no longer has to bear the load of the surface heat exchanger.

In addition, such a building board or cover plate is preferred for optical and/or acoustic reasons.

Such a building board or cover plate can, for example, be a plasterboard.

The invention solves the problem according to a further aspect with a surface heat exchanger according to claim 9, which is particularly characterized in that a strip element protruding outwards beyond the edge of its carrier plate has an adhesive surface in precisely this area. This adhesive surface is used in particular for attaching the surface heat exchanger to a support profile of an air-conditioned ceiling or air-conditioned wall.

From the above-mentioned prior art document of the applicant, it was already known to provide a carbon strip on the carrier plate of a surface heat exchanger, which was intended to serve as a thermal bridge to a holding profile. However, this carbon strip did not provide an adhesive mounting surface for connecting to a holding profile.

According to a preferred embodiment of this aspect of the invention, it is provided that the mounting adhesive surface is provided or covered with a manually removable protective layer or protective film, in particular for transport purposes.

This protective layer or film prevents the surface heat exchanger from accidentally sticking during transport or storage.

The protective layer or protective film can be removed at the installation site as described above to activate the mounting adhesive surface.

With regard to the surface heat exchanger, it should be noted that all claims and features as well as advantages described in connection with the method according to the invention are of course also transferable to the patent claims relating to the surface heat exchanger and should be considered disclosed in connection with these. For reasons of clarity, they are not explicitly repeated here in connection with the claims directed at surface heat exchangers. The same applies the other way round, of course.

In particular, in this context, surface heat exchangers are also disclosed in which the strip element is thermally conductive and/or flexible and/or designed as an adhesive tape and/or as a metal (foil) tape and/or carbon-free.

All disclosed features are essential to the invention in themselves. The disclosure of the application hereby also includes the disclosure content of the associated priority documents (copy of the prior application) as well as the cited publications and the described devices of the prior art. nik in its entirety, also for the purpose of incorporating individual or several features of these documents in one or more claims of the present application.

1 shows, firstly, in a very schematic plan view, a surface heat exchanger 10 according to the invention. This has a, in particular metallic, carrier plate 11, which in the present case is part of a holding cassette 12, which, in addition to the area formed by the carrier plate 11, also has edges 13, which (as will be explained later with reference to 2 described in more detail below) protrude approximately at right angles from the plane of the carrier plate 11.

On the viewer in 1 A pipe system 15 is fixed to the upper side 14 of the carrier plate 11 facing the heat exchanger 12. In the present case, the pipe system 15 is fixed in the area of the straight pipe sections 16 by strip-like heat conducting plates 17 on the upper side 14 of the carrier plate 11. For this purpose, the heat conducting plates 17 overlap said straight pipe sections 16 and are glued in strips to the upper side 14 of the carrier plate 11 next to the straight pipe sections 16. For the sake of completeness, it should be noted that this is merely an exemplary embodiment of the pipe system 15 and its attachment to the carrier plate 11. Alternatively, a different pipe system shape can of course also be provided. For example, instead of the meander shown, a harp shape or another suitable shape can be selected. The attachment can also be carried out in a different way than with overlapping heat conducting plates. For example, heat conducting plates can also be completely under the pipe system 15, or the pipe system 15 can be welded to the upper side 14 of the carrier plate 11 or the like.

The pipe system 15 can, for example, consist of metal, in particular of copper or aluminum or titanium or the like and/or have a round or, in particular in the region of the straight pipe sections 16, D-shaped cross-section.

1 It can also be seen that the carrier plate 11 has a width B (i.e. in the area between the two edges 13).

In the present case, an adhesive element 18 projects over the edge 13 of the carrier plate 11 on each side. Said adhesive element 18 has, for example, approximately a width K and is on the side facing the viewer according to 1 The projection of the adhesive element 18 thus has a width Ü, whereby a projection of each adhesive element 18, 18' in 1 can be seen on both sides of the carrier plate 11.

Said projection provides an assembly adhesive surface 19, with which the surface heat exchanger 10 can be attached in a later process step to 1 will be glued to ceiling-side retaining profiles not yet shown.

Since a surface heat exchanger 10, as shown in 1 shown, is usually made at a first location, namely typically the location of the surface heat exchanger manufacturer, shows 1 in the area of the projection of the adhesive elements 18, 18' there is a protective layer 21 which covers the mounting adhesive surface 19 and thus secures it for transport. The protective layer 21, which can be a plastic protective film, for example, is thus also designed in the form of a strip or band and can be removed manually, for example with the aid of a rear grip surface 22.

In other words, the surface heat exchanger 10 can be 1 from a first location to a second location, namely the installation location, and at the installation location the protective layer 21 can then be manually removed or peeled off (with the aid of the rear grip surface 22) before the surface heat exchanger 10 is attached to a room ceiling.

2 then illustrates the installation of the surface heat exchanger 10 according to 1 on two holding profiles 20, 20' shown in cross-section (arranged in parallel).

The retaining profiles 20 are made of metal and are so-called “C-profiles”. They are attached to a 2 however, it is only attached to the ceiling, which is only indicated by a reference number 23 but is not actually constructed. The surface heat exchanger 10 is also mounted on the ceiling side.

2 represents a state in which the surface heat exchanger 10 is attached via the mounting adhesive surfaces 19 (from which the protective layers 21 were previously removed) between the holding profiles 20, 20'.

The mounting adhesive surfaces 19 of the adhesive elements are glued to the respective underside 24, 24' of the holding profiles 20, 20'.

In a preferred embodiment, the adhesive elements 18, 18' take up the total weight of the surface heat exchanger 10.

In an alternative embodiment not shown, the surface heat exchanger 10 can also be additionally secured or held by other mechanical holding means not shown (such as holding hooks which are attached to the holding profile 20 or the holding profiles 20, 20').

Since the adhesive elements 18, 18' can in particular be metal foil tapes or metal foil strips, a gap 25 between the surface heat exchanger 10 and the holding profile 20 or 20' is also thermally bridged.

This shows 2 that the inner distance A between the holding profile 20 and the holding profile 20' is greater than the width B of the carrier plate 11, since construction-related tolerances must be taken into account. The gaps 25 that result from this are thermally undesirable, however, since this generally means that there is a thermally active area under the air-conditioning ceiling itself. In the state of the art, no significant heat release or corresponding temperature exchange can be seen in the area of the gap 25 (and in particular the holding profile 20) in corresponding thermal images.

However, if the adhesive element 18 is designed to be thermally conductive (in particular by being designed as a metal foil strip), the said area can also be thermally activated and the gap 25 can thus be bridged.

2a shows an enlarged view of the 2 outlined area (the same applies to some of the other figures).

In the previously described fixing of the surface heat exchanger 10 to the support profiles 20, 20' according to 2 With the help of the adhesive elements 18, 18' (which can fully or partially bear the weight of the surface heat exchanger as described above), this is typically only a type of pre-assembly.

In fact, 3 that after said pre-assembly, a cover plate 26 is usually placed from below onto the surface heat exchanger 10 and the support profile 20. This cover plate 26 can be, for example, a plasterboard, which, in contrast to the "raw" arrangement of a surface heat exchanger 10 including support profiles 20 on the ceiling, can offer improved optical and acoustic properties.

According to evidence 3 the cover plate 26 is typically fixed to the holding profiles 20 and 20', in particular screwed (for which screws 27 are only indicated as an example here).

To 3 Finally, it should be noted that the proportions may be slightly distorted here, at least in comparison to 2 .

With the completion of the arrangement according to 3 The process for producing an air-conditioned ceiling is then typically essentially completed.

Heated or cooled water can then be passed through the pipe system 15, whereby it should of course be noted that the ends of the 1 The pipe system shown is typically connected to the ends of adjacent surface heat exchangers, for example via suitable hoses or connectors or similar.

The following figures then show variants which essentially correspond to the (pre-assembled) state of the climate ceiling according to 2 (whereby in the following figures a cover plate 26 is then subsequently fitted as in 3 shown, can be attached).

A first modification of a surface heat exchanger according to the invention shows 4 , whereby a first difference is that, with respect to the figures, no adhesive element 18 is provided in the right-hand area of the heat exchanger 10', but only in the left-hand area. In the right-hand area, a pre-assembly element (not shown) in the form of a hook or similar can be provided merely as an example, which connects the surface heat exchanger 10' to the holding profile 20' for the purpose of pre-assembly and holds it to it.

This embodiment is therefore intended to illustrate that surface heat exchangers which are arranged between two holding profiles typically have adhesive elements 18 on both sides for fixing to the holding profiles 20, but this does not necessarily have to be the case, but the invention also basically includes variants which are glued on one side, as in 4 shown, are included.

This idea should of course apply to all embodiments shown, but for reasons of clarity it is not repeated for each embodiment.

A further difference is that the surface heat exchanger 10' has a carrier plate 11', which continues under the holding profile 20. On the upper side 14 of the carrier plate 11', an adhesive element 18' can be arranged, which does not have the adhesive mounting surface 19 on the same side with which the adhesive element 18 is glued to the carrier plate 11, but on the opposite side.

In such configurations, no lifting would occur in this area when a cover plate 26 is subsequently attached.

Another alternative embodiment shows 5 , where the only difference (compared to 2 ) with regard to the surface heat exchanger 10" according to the invention consists in the design of the adhesive element 18''. In this case, this is designed in two parts: The adhesive element 18'' comprises on the one hand a double-sided adhesive tape 28 and on the other hand a metal foil 29. The metal foil 29 serves in particular for heat transfer, while the double-sided adhesive tape 28 has fixing properties. In other words, no one-piece adhesive element is provided directly, but the adhesive element 18'' is provided here from several parts or areas and can also be produced one after the other: For example, the double-sided adhesive tape 28 can be attached first and only later can the underside of the double-sided adhesive tape 28 be provided with metal foil 29, (at the latest) shortly before a cover plate is attached from below.

The embodiment of a surface heat exchanger 10''' according to 6 then differs from the embodiment according to 2 in particular in the orientation or arrangement of the adhesive element 18'''. This adhesive element 18''' is also a substantially flexible adhesive element, in particular in the manner of a metal foil tape or strip, which in the present case is not glued to the underside 24 of the metal profile 20, but rather to the inner side 30. On the other hand, the adhesive element 18''' is not glued to the underside of the carrier plate 11, but to the projecting edge 13, namely in particular to its outer side.

Depending on the design, the surface heat exchanger 10''' can be 6 or 6a after the fastening shown, it will then sag slightly downwards (due to the flexural flexibility of the adhesive element 18''') and thereby dissolve the inverted U-shape or n-shape shown. On the other hand, a non-flexible but rather rigid adhesive body (or adhesive element) could also be used, which retains the shape shown.

7 then shows a further slight modification of the arrangement of the adhesive element 18'''', in which the adhesive element 18'''' contacts basically the same surfaces, but does so on their opposite sides: Thus, the adhesive element 18'''' is evidently 7 or 7a glued to the inner side 32 of the edge 13 and also to an inner side 33 of the inner side 30 of the holding profile 20. With regard to a rigid or flexible design, this applies to 6 Said analogously.

A slight modification of the adhesive element 18 then shows 8 . Here, the adhesive element 18''''' is designed as a (spherical) adhesive body. It is therefore not a strip or a band, but a spherical body. It can be, for example, a preformed or easily deformable adhesive mass or a quick-drying, initially viscous adhesive mass which is, for example, injected or glued into the gap 25 or something similar. Preferably, this adhesive element 18'''''' is also thermally conductive.

8 further illustrates that different alternatives already presented can also be combined with each other, since in the right-hand area according to 8 a conventional configuration (as in 2 shown). Of course, both sides of the surface heat exchanger 10''''' can also be glued to the holding profiles 20, 20' using non-strip-shaped adhesive elements.

A final alternative embodiment shows 9 According to this, it is first of all clarified that the holding profile 20 does not have to be a metallic holding profile. Rather, holding profiles 20'' and 20''' made of wood or another suitable building material can also be provided.

In this case, the wooden retaining profile 20'' (or 20''') is, purely as an example, completely bonded to its underside 24' by an adhesive element 18, which then continues on the other side of the profile and is also bonded to the next surface heat exchanger.

This embodiment shows that it is basically even possible to completely bridge a holding profile and both adjacent gaps with a single adhesive element (which adhesive element should of course preferably be thermally conductive).

Although all figures show a ceiling-side arrangement of the surface heat exchangers, a wall-side arrangement is also to be disclosed analogously, in which a climate wall is produced. and the profiles are arranged particularly on the wall side, preferably vertically aligned.
