Definitions

  • the present invention initially relates to an intermediate product for the production of a surface heat exchanger.
  • Such intermediates are known in principle from the prior art, for example from DE 10 2015 008 082 A1 the applicant.
  • an intermediate product is described which can be glued in a holding cassette or a so-called "sail", the holding cassette in turn being attached to a ceiling or wall of a building space for air conditioning.
  • the side of the holding cassette facing the interior of the room thus blinds or conceals the intermediate product attached to the other side of the holding cassette.
  • the intermediate product can in particular be produced at a different location from the holding cassette and then brought to the assembly site in order to be glued to the holding cassette only there.
  • the intermediate product therefore has a protective layer covering the adhesive layer of the intermediate product, in particular for transport.
  • the adhesive layer is located on the intermediate product on a first side of a carrier plate, with a pipe system being fixed on the opposite other side of the carrier plate, in particular with the aid of a heat-conducting element. A cool or heated medium will later flow through the pipe system when the surface heat exchanger is installed and finished.
  • Such double-sided adhesive tapes typically consist of a central carrier which is coated on both sides with an adhesion promoter (so-called primer) in order to hold an adhesive on each of its sides.
  • primer an adhesion promoter
  • a corresponding removable protective layer is then located on the outside of at least one of the adhesives.
  • the invention solves the problem with the features of claim 1, in particular with those of the characterizing part and is accordingly characterized in that the adhesive tape used is designed without a carrier.
  • the idea of the invention consists in using what is known as a transfer adhesive tape as the prefabricated adhesive tape of an intermediate product.
  • Such adhesive transfer tapes may be known in principle from the prior art, but their use in Surface heat exchangers (or at least intermediate products for the production of surface heat exchangers) are not.
  • thermal conduction properties of such a tape are more advantageous since heat that is transferred between the carrier plate or the pipe system on the one hand and the holding cassette on the other hand does not have to be additionally transported through the carrier, layer or core.
  • the carrier-free adhesive tape also has a smaller thickness overall, so that the transmission or transport path for the heat or temperature properties is shorter and therefore optimized.
  • the adhesive tape used according to the invention advantageously consists only of an adhesive body and a protective layer covering it on one side, for example made of (special) paper, film or the like.
  • the adhesive tape is also primer-free.
  • the adhesive tape is typically in one piece and, to produce the intermediate product, can have been pulled off and severed from a roll or a corresponding stamped part in the manner of a roll, or it can also have been severed from a sheet or the like.
  • prefabricated means in particular that the adhesive tape is essentially present as a prepared body, preferably already has a protective layer and together with this forms a unit.
  • This unit may have been previously severed from a roll or sheet, or the like, as described.
  • double-sided adhesive tape also called double-sided adhesive tape which has no backing.
  • the adhesive tape is continuously adhesive, i.e. has no non-adhesive core.
  • adhesive transfer tape which consists only of an adhesive film with a protective layer
  • foam adhesive tape which - again with the exception of the protective layer - consists of adhesive through and through
  • the adhesive tape can consist exclusively of foam and the protective layer or from self-adhesive foam plus additional adhesive film and protective layer
  • adhesive tapes of the first type ie those which only comprise an adhesive film together with a protective layer, are particularly advantageous because they are equipped in particular with particularly good thermal conductivity properties.
  • the adhesive tapes which are used in the intermediate product according to the invention before they are added to the intermediate product, of course also, in addition to the outer protective layer, on the other side can provide another protective layer (e.g. in the form of a release layer or the like) (so-called liner), which essentially prevents adhesive tape on a roll or anywhere else from sticking to the layer above.
  • liner e.g. in the form of a release layer or the like
  • the outer protective layer can in particular be silicone paper, since this is particularly well suited to protecting the adhesive body or adhesive film well and, on the other hand, being able to be removed again manually, even after a long period of time.
  • the protective layer can of course be formed in one piece or alternatively also in several parts (for example consisting of several strips arranged next to one another or the like).
  • the holding cassette typically has a fastening surface in its interior which is designed to be flat.
  • exactly one surface heat exchanger is installed in a holding cassette.
  • the holding cassette can be associated with holding means for attachment to a wall or to a ceiling of a building space in a conventional manner.
  • a cassette can also have so-called acoustic perforations.
  • the cassette is not closed in this sense, but has perforations on its surface, ie in particular in the area of the fastening surface, which are typically arranged regularly and in the form of a grid. In this case, it makes sense that the intermediate product to be introduced into the holding cassette also has congruent perforations, at least in the area of the carrier plate and possibly the adhesive tape/body.
  • the protective layer does not need to have these perforations, since they are peeled off or removed before the surface heat exchanger is completed.
  • a surface heat exchanger produced in this way is usually installed together with a plurality of identical surface heat exchangers on a ceiling or a wall of a building, as seamlessly as possible, in order to offer a homogeneous appearance.
  • the pipe systems of the individual surface heat exchangers can be fluidically be connected, in particular through openings in the side walls of the holding cassette or the like.
  • Such a large number of surface heat exchangers can also be referred to as a climate ceiling or climate wall. It serves to air-condition the room, ie in particular to heat or cool the room.
  • a hot medium in particular water
  • a cold medium also preferably (chilled) water
  • the pipes consist in particular of copper, but can also consist of any other suitable metal or other material, such as a suitable plastic.
  • the tubes of a single surface heat exchanger have a meandering shape, ie they consist of sections that are straight and curved sections.
  • the straight sections have a D-shape in cross section and the round sections have a circular shape in cross section.
  • the pipe system is typically fastened to the carrier plate with the aid of heat conducting plates, which are either glued to the carrier plate (preferably also with carrier-free adhesive tape) or are fastened in some other, in particular mechanical, way (e.g. positively).
  • heat conducting plates which are either glued to the carrier plate (preferably also with carrier-free adhesive tape) or are fastened in some other, in particular mechanical, way (e.g. positively).
  • strip-like heat conducting plates can be provided, which are further assigned in particular to the straight tube sections and overlap them on both sides or at least on one side, fastened.
  • the protective layer can be removed from the intermediate product in order to assemble the surface heat exchanger and this can then be glued manually, in particular under pressure, over the entire surface or snugly to the fastening surface of the holding cassette.
  • the holding cassette is typically made of metal or steel and can in particular also be designed to be magnetic. It can also be called a sail and the heat exchanger using it is also called a cassette-type heat exchanger.
  • the heat conducting sheet(s) usually consist of materials with good thermal conductivity, so that in particular a heat conducting function is provided in order to transfer the temperature of the medium to the carrier plate.
  • the heat conducting sheet naturally also has the function of fixing the pipe system (or a pipe system section) and at the same time pressing it against the carrier plate under constant tension. Therefore, the heat conducting sheet is typically made of spring-hard metal.
  • the metal carrier plate which is at least 3 mm thick (steel can also be used if necessary), the temperature can be transferred even more optimally.
  • the metal support plate preferably has a thickness of at least 0.5 mm and more preferably at least 0.6 mm. Sheets that are too thin, such as those known from the non-generic area of refrigerator technology, cannot be used because on the one hand they bend easily and on the other hand do not allow a decent heat transfer, which is particularly important for surface heat exchangers in the field of building air conditioning.
  • the carrier plate together with the pipe system and heat conducting plate is assigned to the inside of the cassette facing away from the room.
  • the carrier plate is made of aluminum, which enables particularly good thermal conductivity.
  • the outer protective layer which covers the adhesive layer, is designed in the form of a film or sheet and can be removed manually without tools.
  • the protective layer can therefore be a film or a (silicone) paper or the like, which is suitable for being manually removable from the adhesive body of the adhesive tape.
  • the protective layer to have a pulling surface or gripping surface.
  • this pulling surface can be the rear side of the protective layer, which can be gripped behind with a fingernail, for example.
  • the protective layer can be easily pulled off at one corner and then grasped from behind.
  • the protective layer can of course also provide a separate tab, in particular in a corner area, which makes it easier to pull off or remove the protective layer.
  • the carrier plate looks black on the side having the adhesive layer after the protective layer has been removed. This enables optical advantages, especially if the carrier plate including the pipe system (i.e. the rest of the intermediate product after the protective film has been removed) is to be glued directly to the holding cassette (i.e. without a black fleece in between).
  • This embodiment of the invention is particularly suitable for cases in which the holding cassette is not closed but perforated in the region of its attachment surface and--as described--no fleece is used.
  • the effect of a black color can be achieved, for example, by a separate layer underneath a transparent adhesive tape.
  • a black-colored adhesive tape can of course also be used.
  • the holding cassette has both a width and a length of at least 50 cm. Retaining cassettes with smaller dimensions have proven to be unsuitable for assembly, in particular for optical reasons, but also for reasons of ease of assembly and stability.
  • Typical holding cassettes have a width and a length of about 60 cm.
  • Alternative holding cassettes that are not square and are more elongated can have dimensions of 60 ⁇ 120 cm, for example.
  • the carrier plates of the intermediate product typically have dimensions with edge lengths of about 30 to 120 cm.
  • the edge length of the corresponding carrier plate must be at least slightly less than the edge length of the holding cassette, so that the carrier plate and thus the rest of the intermediate product can be introduced into the holding cassette without any problems after the protective layer has been pulled off.
  • Typical carrier plates have dimensions of 30 ⁇ 30 cm to 50 ⁇ 50 cm, for example. However, for larger sails are also self-evident larger carrier plates can be provided. However, both edge lengths are typically at least 20 cm or 30 cm long, but typically do not exceed 250 cm in length/width.
  • the intermediate product is bonded undeformed to the fastening surface.
  • the protective layer has been removed, it is actually not, strictly speaking, the intermediate product, but rather the rest of the intermediate product.
  • the remainder of the intermediate product or the carrier plate is glued undeformed to the fastening surface, so that for example the carrier plate is not kinked or angled or the like for this purpose. This is usually not even possible due to the greater material thickness. Since the carrier plate together with the adhesive body of the adhesive tape extends essentially along one plane, the carrier plate is also bonded essentially along one plane to the planar fastening surface.
  • the remainder of the intermediate product is preferably glued to the fastening surface essentially over its entire surface, it being possible, for example, for the adhesive body to be applied continuously and without gaps to the carrier plate.
  • the adhesive body of the adhesive tape can also have perforations or the like, in particular if perforations are also provided either in the fastening surface of the holding cassette and/or on the carrier plate.
  • perforations are also provided either in the fastening surface of the holding cassette and/or on the carrier plate.
  • this is still considered to be essentially the entire surface within the meaning of the present invention. This is to be understood in particular as not merely adhering at certain points.
  • the carrier plate it can be advantageous for the carrier plate to have an essentially continuous adhesive body for this purpose only on one side. No continuous adhesive body is therefore provided on the other side assigned to the pipe system.
  • the heat conducting plates can be attached to the other side with adhesive or adhesive tape, this is usually only in the form of strips and not continuously.
  • the side of the intermediate product or the remainder of the intermediate product that has the adhesive layer is preferably glued to the fastening surface in a plane-parallel manner.
  • two surfaces which extend essentially along a parallel plane namely the fastening surface and the adhesive tape or the underside of the carrier plate, are moved towards one another as parallel as possible, so that the two planes come to rest on one another. A user can then manually help to bond the two surfaces by applying pressure.
  • neither the said side of the intermediate product or the said side of the carrier plate nor the fastening surface have any recesses. It is true that minor perforations, in particular grid-shaped acoustic perforations, can be provided. Recesses in the sense that either the fastening surface or the carrier plate has areas in the manner of deep-drawn, recessed areas would probably not allow full gluing.
  • the adhesive tape is designed to be essentially free of cavities in the area between the protective layer and the adhesive body.
  • the invention thus offers the advantage that a prefabricated adhesive tape is used in which cavities of this type can be ruled out from the outset.
  • Essentially free of cavities means that no relevant cavities exist. In the microscopic sense, cavities can be found everywhere, but these are not meant. Rather, what is meant are cavities that can arise when separate adhesive layers are applied manually or by machine and are provided with a separate protective layer.
  • the area between the protective layer and the adhesive body can be designed without cavities.
  • the adhesive tape consists of a protective layer and an adhesive body. So it includes neither a carrier nor a primer or the like.

  • the finished intermediate product 10 according to 2 are first transported from the location of the manufacturer to a location of a fitter who is based near the installation site.
  • the protective layer 21 or protective film 21 can be easily removed or peeled off manually. In this way, the adhesive body 20 of the intermediate product 10 is exposed. For this purpose, a user can manually reach behind a gripping surface 18 of the protective layer 21 .
  • a black color impression for example.
  • This can be produced, for example, by a black-colored adhesive body 20 of the adhesive tape 31, or in an alternative, not shown embodiment, by a separate coating of the underside of the carrier plate 11, which would thus be arranged between the carrier plate 11 and the adhesive body 20, in which case a substantially transparent adhesive body 20 would have to be used.
  • the removal of the protective layer 21 according to 3 preferably takes place immediately before the remainder 22 of the intermediate product is glued in or on a holding cassette 23, as is shown in 4 is shown.
  • the remainder 22 of the intermediate product 10, in particular including the exposed adhesive body 20, the carrier plate 11 and the pipe system 13 and the heat conducting plates 16, can then be approached along an insertion direction E to the inside 24 of the holding cassette and glued there with the help of the exposed adhesive body 20 of the adhesive tape 31, in particular over the entire surface.
  • This gluing takes place essentially plane-parallel in that the plate plane P is brought plane-parallel to the fastening plane B of the holding cassette 23 until it is glued to a fastening surface 25 of the holding cassette 23 . No tools, aids or the like are usually required for this. A user can do this manually, in particular by Placing the remainder 22 of the intermediate product 10 in or on the holding cassette 23 or the fastening surface 25 exerts pressure approximately along the insertion direction E on the rear side 24 of the carrier plate.
  • the finished surface heat exchanger is then in figure 5 marked with the reference numeral 26.
  • This has in particular an adhesive tape 32 without a protective layer (which corresponds to the adhesive tape 31 without the protective layer 17, ie the adhesive body 20).
  • a further exemplary embodiment is not shown, which provides that the fastening surface 25 of the holding cassette 23 is provided by a preferably black fleece arranged in the holding cassette.
  • This optional fleece has, among other things, acoustic and optical properties and can already be introduced into the cassette 23 in a separate method step.
  • the surface heat exchanger 26 can now be brought from the second site, for example the site of the local fitter, to the assembly site, in particular the intended building space. However, if the surface heat exchanger 26 was already completed at the installation site, it can now (as evidenced by 6 ) the final assembly of the finished surface heat exchanger 26 take place.
  • 6 1 shows the surface heat exchanger 26 in a fully assembled state, for which purpose the surface heat exchanger 26 has been attached or fastened to a ceiling 27 of a building room 28 .
  • the surface heat exchanger 26 in 6 but only the holding cassette without the remainder 22 of the intermediate product 10 is shown.
  • the fully assembled surface heat exchanger 26 includes all in figure 5 components shown.
  • the holding cassette 23 can be used, for example, in 6 implied, and in figure 5 have mounting surfaces omitted for the sake of clarity, which in particular are attached to the side edges 29 of the holding cassette 23 (cf. figure 5 ) can connect.
  • the surface heat exchanger 26 is in 6 together with other surface heat exchangers 26' and 26" in a cascade-like manner on the ceiling 27.
  • Complete assembly also includes, among other things, that the surface heat exchanger 26 is connected to the other surface heat exchangers 26' and/or 26" with regard to its pipe system, so that a continuous line of a fluid flowing through the pipe system 13 is secured on the ceiling 27.
  • the surface heat exchanger not only, as shown in the sectional view 6 shown, but also be arranged one behind the other with respect to the other spatial direction.
  • the surface heat exchangers 26 form a so-called air-conditioning ceiling, which ensures that the room 28 is air-conditioned. If a cooling medium, for example chilled or cool water, flows through the pipe systems or the pipe system, the air-conditioning ceiling can have a cooling effect. If the room 28, however, are heated, the pipe systems 13 can Are surface heat exchanger 26 with heated medium, such as hot water, flows through.
  • a cooling medium for example chilled or cool water
  • a typical surface heat exchanger 26 has a width b of about 60 cm, in particular between 50 and 70 cm. In the other spatial direction, the surface heat exchanger 26 can have identical dimensions or, alternatively, typically also dimensions that are approximately twice as long, ie, a length of approximately 120 cm or, in particular, between 100 cm and 140 cm. Typically, exactly one intermediate product (remnant) 22 is arranged or installed within a holding cassette.
  • Figures 7 and 8 show in a very schematic representation, some in sections, the difference between a double-sided adhesive transfer tape as used according to the invention ( 8 ), and a prior art backed double-sided pressure-sensitive adhesive tape ( 7 ).
  • the adhesive tape 31 used according to the invention 8 only has an adhesive body 20 and a protective layer 21 (whereby, for the sake of clarity and because of the schematic representation, these are not shown to scale, in particular with regard to their thickness, and are also not shown in the correct relation to one another), there is a double-sided carrier tape with a carrier, as is shown in 7 is shown, consists of many more layers: it has a central support 36 and a layer of primer material 37 or 37' on both sides. This serves to connect the respective Adhesive masses 38 or 38' on the backing 36.
  • the adhesive tape with backing is also shown to have 7 then a protective layer 21'.
  • the double-sided adhesive tape with backing 7 is thicker overall and has, for example, a total thickness of more than 0.2 mm, while the carrier-free adhesive tape 31, as used in the invention, has a significantly lower total thickness, for example less than 0.15 mm.
  • the adhesive body 20 in the adhesive tape 31 has a smaller thickness of, for example, about 0.06 mm than the protective layer 21 (which can consist, for example, of silicone paper and can have a thickness of about 0.08 mm).
  • FIG. 9 shows 9 another embodiment in a view from below, which is a view according to about Fig.1e corresponds, in which the underside 19 of the carrier plate does not (any longer) have a protective layer, but already has a decorative layer 39 arranged on it.
  • this decorative layer 39 is, for example, a fleece, in particular an acoustic fleece.
  • the decorative layer 39 is shown to have 9 in particular a (in this example checkered) pattern, which can be printed on the decorative layer or the fleece, for example.
  • the decorative layer 39 is glued to the underside 19 of the surface heat exchanger 40, through the 9 adhesive body 20 of the adhesive tape 32 indicated at one corner.
  • the decorative layer 39 has, as in 9 shown, of course there is no "dog-ear" in the area of a corner.
  • This illustration is only intended to make it clear that the adhesive body 22 , by means of which the decorative layer 39 is fastened directly to the underside 19 of the carrier plate 11 , is underneath the decorative layer 39 but above the underside 19 of the carrier plate 11 .
  • slightly modified surface heat exchanger 40 shows, this is also an easy-to-handle, ready-to-use and transportable unit that is produced at a first location.
  • a surface heat exchanger 40 according to the invention can therefore be transported to its destination in a logistically easy manner.
  • a surface heat exchanger 40 can have assembly means, for example, or it can interact with assembly means on the room or ceiling side. It is typically not glued into a holding cassette since the underside with the decorative layer 39 should just be visible.
