    Description: [0001] The invention relates to heat exchangers, in particular surface heat exchangers of the kind that can also be used, for example, in the form of prefabricated panels in a heat exchanger ceiling, wall cladding, in a solar collector and generally as air conditioning components.
    DE 10 2004 057384 B4 discloses heat-conducting profiles which can be integrated into a DIN-compliant standard ceiling system and / or into a DIN-compliant special construction.
    However, there is a need for mass production heat exchangers that can be assembled in particular to air and / or solar components. In particular, there is a need for heat exchanger elements with increased cooling and / or heating power per unit area.
    The object of the present invention is to provide a heat exchanger comprising a heat exchanger element and at least one carrier, which is mass production suitable and at the same time ensures effective heat exchange of the environment with the heat transfer medium by effective heat conduction.
    The solution of the object is disclosed by the subject matter of the present invention, as shown in the description, the figures and the claims.
    The present invention is therefore a heat exchanger, comprising at least one carrier with receiving device and at least one heat exchanger element, wherein the at least one heat exchanger element comprises at least one housing with an inner heat transfer tube and is fixed on at least one carrier via the receiving device, wherein at least one Element of housing, support and / or receiving device by a mass production suitable processing, in particular deformation of a sheet material can be produced.
    General knowledge of the invention is that by applying fins, which are used as housing for heat exchangers, in particular heat exchanger tubes, it is possible to achieve more convection and thus increased performance at the same projected area of the panels.
    As a "sheet material" in the context of the present invention, for example, a sheet, a film, a belt-like material, for example, endless belt material and / or a plate referred to. In particular, materials made of thermally deformable material fall under this name.
    These can be converted mass production in processing processes such as drawing, rolling, edges to the respective element, so for example to the housing, the carrier, the receiving device and / or a part thereof.
    General knowledge of the invention is that in heat exchangers such as those described above, the hitherto customary, usually consuming, and for example extruding comprehensive manufacturing process by simple and above all mass production, in particular automatable, manufacturing methods is replaceable.
    For example, the production of the housing of sheet material can be carried out continuously in the roll-to-roll Ver drive.
    According to a further advantageous embodiment, the housing is in the form of a lamella. In the present case, a lamella refers to a body which has a large aspect ratio, that is to say whose extension into the depth is small compared with its length and width extent. In extreme cases, a lamella is flat, for example, has only the height of the jacketed heat transfer tube.
    According to an advantageous embodiment, for example, the housing has a wall thickness of less than 1.5 mm, preferably less than 1.3 mm, more preferably less than 1.2 mm in particular even less than 1.0 mm, more preferably less than 0.8 mm and most preferably less than 0.5 mm. For example, the wall thickness of the housing is in the range of 0.3 mm to 1.2 mm.
    Low wall thicknesses of the housing are advantageous in many respects, they are light in weight, lead to material and cost savings and / or are easier to deform than thick wall thicknesses.
    Such low wall thicknesses are mass production suitable by conventional manufacturing processes, by the example so far lamellar housing in the context of the present invention - ie housing with internal heat transfer tubes - are produced, not achieved. However, a smaller wall thickness is favorable both for the heat transfer and for the weight of the panels, which are for example mounted on the ceiling.
    By the method presented here for the preparation of the elements, in particular of the housing for the heat exchanger described above by mass production suitable processing of sheet material low wall thicknesses for such housing such as wall thicknesses less than 1.5 mm, cost feasible.
    According to an advantageous embodiment, it is at the heat exchangers to suspension elements, which are attached to a raw ceiling and / or shell wall. The suspension elements can be handled in the form of panels.
    In the heat exchanger flows through the heat transfer tube, a heat transfer medium, such as water, air and / or other. The heat transfer medium circulates in the heat transfer tube in such a way that it assumes the heat at one point and gives it off again elsewhere. As a rule, several heat transfer tubes of several panels are connected to a circulatory system.
    In general, the heat transfer tube is completely covered by the housing.
    According to one embodiment, the housing in which the heat transfer tube is located, a surrounding at least on three sides of the heat transfer tube shell.
    It may further be provided that the housing is at least partially made of perforated material. The perforation also serves room acoustics.
    As a material for the carrier and / or the housing, for example, a deformable sheet and / or a sheet-like workpiece, such as a sheet or a film may be used, wherein the "sheet" or the film is not necessarily made of a metal such as Aluminum or iron and / or an aluminum and / or iron alloy and / or other alloy and / or other metal. In this case, the housing may be made of the same material as the carrier or of another material.
    Thus, the carrier and / or the housing, both of the same or of different materials. For this, materials are preferably selected which are as light as possible, thermally conductive, ductile and / or mechanically resilient, such as, for example, metal, metal alloy and / or metal hybrid and / or other plastic, in particular fiber-reinforced plastic, such as thermoplastic or duroplastic.
    For example, for the carrier and / or for the housing, a filled thermally conductive plastic, such as a filled with thermally conductive particles plastic, are used. The thermally conductive particles may be made of any materials, metallic, micaceous and / or other fillers, wherein the particles themselves are thermally conductive and / or have a heat-conductive coating. This coating can cover the housing both outside and inside as well as on both sides, in whole or in part.
    The size of the filler particles can vary within wide ranges, for example, nanoparticles as well as microparticles can be used as a filler. For example, plastics with multiple fractions of fillers differing in material, shape and / or size are used. It can be used with any fillers of fillers depending on the requirements of plastics, as is known to those skilled in such lightweight construction plastics specialist.
    In addition to the housing, the carrier can also be made together with the receiving device from a flat workpiece by mechanical deformation such as rolling, pressing, drawing, edges and / or other.
    To produce the heat exchanger element, the housing can be equipped with the heat transfer tube in an automated and also - as the production of the housing - preferably continuously guided process. The attachment of the lamellar housing in the receiving device of the carrier or the carrier profile can be automated by a suitable choice of the brackets.
    It is particularly advantageous that the entire heat exchanger element can be produced automatically in a continuous process by the nature of the connection between the blade and carrier, so for example by simply clipping the blade into the receiving device of the carrier.
    According to an advantageous embodiment, the shape of the bulge of the receiving device corresponds to the edge or the part of the edge of the blade, which comes to lie in it. For example, it is possible that the conventional lamellae made of sheet metal - as well as glued-in heat-conducting profiles - may be omitted.
    The carrier or the carrier profile can be connected to other carriers.
    The heat transfer tube is preferably made of thermally conductive plastic, metal or a metal alloy, in particular copper or copper alloys have proven to be suitable material.
    According to an advantageous embodiment of the invention, the housing in the perforated design to improve the acoustic properties with an acoustic fleece and / or an acoustic coating inside and / or outside be equipped.
    The acoustic tile is for example made of cellulose, textile synthetic fiber material and / or a felt-like, sound-absorbing material. Advantageously, the nonwoven at the same time is also difficult to burn, so for example made of flame-retardant material.
    Any existing in the housing, respectively the lamella, existing cavity is partially or completely filled according to an advantageous embodiment of the invention with an absorbent insert. This absorption liner then serves for example as a spacer for the inner heat exchanger tubes.
    In a multi-part housing, for example, a two-part form may be provided, such as shell with cover or similar structures.
    For example, a housing according to the invention comprises a shell closed on three sides, optionally additionally one or more covers on the longitudinal and / or transverse sides. All elements for the construction of the housing or only individual thereof can be made according to the invention simple and mass production suitable by bending a flat workpiece.
    The attachment of the lid to the shell is, as well as the attachment of the housing - so for example the lamella on a support profile - arbitrarily, preferably as simple as possible, for example by snapping, gluing and / or magnetic.
    For example, the closed shell on three sides at least one inner heat exchanger tube. In this case, the heat exchanger tube-preferably at all sides-abuts on the inner wall of the housing, preferably in a material-locking manner, so that as far as possible a heat exchange with the housing takes place.
    In the case of a device is advantageously provided by which the housing can be easily inserted into the receiving device of the wearer. In particular, a fixation of the housing according to the principle piece counterpart is advantageous here, so for example, a bulge into a recess of the counterpart snaps.
    According to such an embodiment, the housing may have a notch into which can be clipped into a "nose" of the receiving device.
    Preferably, the housing and the receiving device of the carrier are coordinated so that no complex fitting of the housing in the receiving device of the carrier, which is preferably present as a simple carrier profile, is required.
    According to an advantageous embodiment of the invention, the lamella projects with the heat exchanger element of its width or its length into the room. It is particularly advantageous if the lamella can be placed on the support on the receiving device in different angles to the wall or to the ceiling.
    By the position of the lamella to the room, the fireplace effect and / or convection generated by the panel can be set and / or controlled in a targeted manner.
    The housing, for example, so the lamella can be fixed selectively or one edge after the carrier.
    In this case, the housing along one edge, possibly only selectively, on one or more carrier (s) made firm, so that in particular the ambient air by convection, so the waste of the heavier colder air down on the outside housing along sweeps and thus enables an effective heat exchange of the room air.
    According to one embodiment, the housing protrudes in the form of a lamella with the width of the lamella in the room and is fixed lengthwise at least selectively on the carrier.
    According to an advantageous embodiment of the invention, the heat transfer tube is located in the interior of the housing close to the housing inner wall. It is preferred that the diameter of the heat exchanger tube to the depth of the housing, so for example, the lamella corresponds. In particular, it is preferred that the heat transfer tube is pressed against the inside of the housing. For example, it is possible to use spacers, holders on the inside of the housing and / or other means for the most conclusive attachment of the heat carrier tube to the housing. More generally, the more coherent the heat transfer tube's concern to the housing, the more effective the heat exchange.
    As spacers, for example, plastic parts, plastic and / or elastomeric parts, absorbent inserts, and other deposits are used.
    In particular, it is preferred if the housing encases the rounding of the heat transfer tube up to 180 ° or more.
    Furthermore, according to one embodiment of the invention, it is provided that the housing has a depression, indentation or elevation, nub, through which the heat carrier tube is held in position in the housing, that is, for example, can be latched or clipped.
    The heat carrier tube is arranged in the housing and in particular so that it is arranged inside the housing along the walls projecting into the room.
    The position of the at least one heat transfer tube in the housing can vary, usually it is designed for the most effective heat transfer possible. Optimally, the heat transfer tube is therefore as firmly as possible and with maximum contact surface in the housing. However, alternative routing is conceivable and included within the scope of the invention.
    For contacting the arranged in the housing heat transfer tube, an inlet and an outlet are provided on the housing, which are part of the heat transfer tube. Through this, the heat transfer tube of a first housing is connected to a further located in a second or further housing heat transfer tube.
    The heat transfer medium, for example water and / or air, flows through these heat transfer tubes successively or in parallel.
    For example, it is provided that the inlet and the outlet are arranged on the same side of the housing or on opposite sides of the housing.
    According to a preferred embodiment, the receiving device and the carrier are produced in one piece.
    Preferably, the housing is accurately connected by the receiving device with the carrier / carrier profile. In particular, retaining means are provided for fixing the housing in the receiving device, by which the housing can be fixed by means of a simple mechanism and / or a screw in the receiving device.
    Advantageously, the heat exchangers are used as surface heat exchanger components, for example, serve to form a heating or cooling ceiling and / or air conditioning element of a wall covering a building. Both interior and exterior walls of the building can be equipped with a heat exchanger.
    Such a heating or cooling ceiling or such a Klimabauteil a building cladding is mounted, for example, ceiling and / or wall side and includes numerous, e.g. grid-shaped panels or panel elements.
    As the heat exchange medium and / or as a coolant in the heat exchanger element in particular water is used, but there are also other heat transfer media used.
    The heat transfer tube is inserted, for example after the manufacture of the lamella by deformation in this and / or inserted and pressed for example by means of a spacer and / or clamping cam or a clip or other means for fixing preferably firmly against the inner surface of the lamella to an optimized Heat transfer from the lamella to the heat transfer tube to ensure.

    Fig. 2 shows a section of the assembled lamella 20 of the two sections shown in Fig. 1. Evident is the shell 4 with the attached lid 1, wherein the edges 2 and 3 are located in the receiving devices 7 and 8. The cross sections of the heat transfer tube sections 5 and 6 can also be seen. In FIGS. 1a, 1b and 2, a perforation 11 of the lamella 20 can be seen in each case. The perforation 11 is shown here over the entire surface, but may also be provided irregularly or not at all in some areas. FIG. 3 again shows the same view as FIG. 2, but with an internal acoustic fleece coating 12. FIG. 4 again shows the arrangement known from FIGS. 2 and 3 with a filling 13 of the lamella 20, for example with mineral wool, acoustic foam, and / or other sound absorbing materials. Fig. 5 shows a section of an exemplary carrier or carrier profile 14 according to the invention in side view. In the detail shown, the carrier 14 has a receiving device 15 for receiving a housing, for example a lamella 20, as is known from FIGS. 1 to 4. When receiving the blade 20 in the receiving device 15, the nose 16 is bent with the bore 17 to the outside. To fix the blade 20 in the carrier 14 is then, not seen in the view selected here, a plug or screw through the nose 16 on the one hand and a perforation hole on the other hand, for example, plugged or screwed. In Fig. 6, two carriers 14 are shown with a plurality of receiving devices 15. In the receiving devices 15 stuck two slats 20 as shown in FIGS. 1 to 4. The receiving devices 15 give the position of the slats 20 to the room, respectively the wall to which the carrier 14 are attached, before a certain angle. In FIG. 7, the representation from FIG. 6 is again shown in perspective from another spatial direction. In addition to the known from Fig. 6 elements, the two carriers 14 with the two inserted slats 20 and each, per carrier 14 an empty receiving device 15 per receiving device 15 comprises two hubs 16, you can see the openings 18 of the slats 20, through the a connection of the inside of the fins 20 heat exchanger tubes 5 and 6, as is known from FIGS. 1 and 2, is provided to a heat exchanger circuit. A number of the fins are fixed to a carrier profile and / or a plurality of carrier profiles, which are joined together to form a wall construction. The solution proposed here is particularly advantageous because the individual slats in the ceiling construction can be made parallel and the effectiveness of the heat exchanger is adjustable by the inclination of the receiving devices respectively the slats for ceiling, roof and / or wall inclination. Due to the inclination of the slats to the ceiling or wall, in addition to the convective part of the heat transfer, a radiation component for heat transfer can be used. The invention shows a preferred closed element such as a housing or a lamella with heat exchanger function and sound absorber function of a preferably thin-walled material. The direct contact of the heat exchanger tube in the example, longitudinal outer edge of the blade causes good heat transfer between the heat exchanger tube and lamella and ensures next to the large heat exchanger surface at the same time a large area acoustically effective surface. Due to the vertical or oblique arrangement of the individual slats this causes in the heating as well as in the cooling case a chimney effect in the room, which causes an improvement in the convective heat transfer from the lamella to the air as well as vice versa with the resulting increased air movement. The overall construction, in addition to the heat exchanger function as a further essential property on a high sound absorption for room acoustics. The acoustic properties are achieved by the perforation of the housing, in conjunction with an applied inside and / or outside acoustic fleece coating. Also, a filling of the housing in addition or as a single measure with mineral wool, acoustic foam or other sound-absorbing materials. A micro perforation of the housing as a single measure to achieve a sound absorption is also possible.
