    专利说明:

    The present invention relates to a heat exchanger device having a first cover plate and at least one second cover plate, wherein between the cover plates at least one heat exchanger tube is arranged with a tube wall. Moreover, the invention also relates to a method for producing a heat exchanger device. Heat exchanger devices of the above type are e.g. shown in DE 102 30 296 A1. There is a support plate between the two cover plates, the e.g. may consist of polystyrene, polyurethane or polypropylene foams. This support plate has recesses into which the heat exchanger tubes are inserted. The cover plates are glued to the support plate, whereby also a thin adhesive layer can remain between the cover plates and the heat exchanger tube.
    The object of the invention is to propose a heat exchanger device of the above type with improved heat transfer between the cover plate and the heat exchanger tube.
    To achieve this object, the heat exchanger device according to the invention provides that the tube wall of the heat exchanger tube on at least one side, which faces one of the cover plates has a shape adapted to the cover plate surface area, which rests flat, preferably directly, on the cover plate.
    By adapted to the shape of the cover plate surface area of Rohnwandung the heat exchanger tube, there is a flat contact of the cover plate on the heat exchanger tube and thus to an improved heat transfer due to the larger transfer area. In contrast to the known in the prior art line-like contact between the pipe wall and the cover plate, it comes on the basis of the invention to a flat concerns of said adapted surface area of the pipe wall to the cover plate. It can be provided that the pipe wall of the heat exchanger tube on opposite sides, which each face the cover plate, each having a shape adapted to the cover plate surface area, both of these adapted surface areas each flat, preferably directly, abut the cover plate , But it is equally possible that such an adapted surface area only on one side, which faces one of the cover plates, is realized. For example, can also be provided on a the matched surface areas opposite side of the pipe wall, an insulating layer to complicate or prevent the heat transfer between the Rohnwandung and existing on the other side of this insulating cover plate. The heat exchanger tube can be arranged meander-shaped or in other embodiments between the cover plates. Of course, there may also be a plurality of heat exchanger tubes in this space between the cover plates, which are all favorably designed according to the invention. The heat exchanger device according to the invention could also be referred to as a heat exchanger cassette. Through the heat exchanger tubes, a heat transfer fluid is usually passed. The cover plates can be designed as massive rigid plates but also as movable plates or the like. Without other materials such as To exclude plastic in principle, the cover plates are preferably metal plates, e.g. made of aluminum, copper or steel. The tube walls of the heat exchanger tubes can also be made of a wide variety of materials, e.g. also made of plastic. Preferably, however, the tube walls are also made of metal, e.g. also made of aluminum, copper or steel.
    In principle, it is provided according to the invention in the sense of the planar system that the adapted surface area of the heat exchanger tube and the area of the cover plate on which it rests have the same shape. In principle, various curved or differently configured surface shapes come into question. However, particularly preferred embodiments provide that the adapted surface area of the Rohnwandung and an area of the cover plate, against which this adapted surface area of the pipe wall, are each flat and just abut each other. In this respect, one could also speak of flattened surface regions of the pipe wall in these embodiments. Outside of these adjusted surface areas, the tube walls can have any other shapes, e.g. they may be designed arcuate or the like in these areas. For example, For example, it is possible to reshape a pipe wall of originally circular cross-section so as to incorporate in it the adapted surface area (s), e.g. just to be trained.
    Seen in a cross-section orthogonal to a longitudinal extent of the pipe wall, the width of the adapted surface area is favorably at least 25%, preferably at least 50%, of the total width of the pipe wall. The total width of the pipe wall is measured from the outside, so it's about the outside not around the inner diameter of the heat exchanger tube.
    In particular, when the tube wall of the heat exchanger tube and the cover plates made of different materials, but also otherwise, it can be provided that the adapted surface region of the tube wall and the region of the cover plate, against which this adapted surface region of the tube wall abut one another slidably against each other. This makes it possible to compensate for different thermal expansions of the Rohnwandung and the cover plate, without causing thereby stresses within the heat exchanger device and without thereby the heat transfer between the pipe wall and the cover plate is adversely affected.
    Although not absolutely necessary, particularly preferred embodiments of the heat exchanger device according to the invention still provide that a space between the cover plates outside the heat exchanger tube is at least partially filled with a foam body. The foam body can fulfill various tasks here. First, it can stabilize the entire heat exchanger device and thus in particular the cover plates and the heat exchanger tube. On the other hand, it can serve as an insulating material between the cover plates. Above all, it can also be used to attach the cover plates together. In this context, particularly preferred embodiments of the invention provide that the cover plates are glued together by means of the foam body. This bonding of cover plates and foam body can be done by applying adhesive. But it is equally conceivable that the bonding of the cover plates with the foam body takes place immediately upon foaming of the foam body and thus by the foam body itself. The foam body can consist of a wide variety of foams known per se in the prior art. Most preferably, it consists of foamable material, e.g. foamable plastic. Preferred here is e.g. To call polystyrene or polyurethane.
    In particular, when the foam body is formed by foaming in a space between the cover plates, preferred embodiments for limiting the gap between the cover plates provide that the space between the cover plates towards the sides, preferably of bevelled edges of the cover plates is closed. In the case of the bevelled edges, the side parts thus consist of bevelled areas of the cover plates. Of course, separate side seals could be mounted between the cover plates.
    As already explained, the invention relates not only to a heat exchanger device per se but also to a method for producing a heat exchanger device. An inventive method for producing a heat exchange device, in particular according to the above type, with a first cover plate and at least a second cover plate, wherein between the cover plates at least one heat exchanger tube with a Is arranged pipe wall, according to the invention provides that the heat exchanger tube is placed between the cover plates, then the cover plates are pressed together with a press and then in the compressed state foam to form a or the foam body in one or the space between the cover plates in the area outside of the heat exchanger tube is introduced and hardens there. In other words, it is thus provided that the cover plates are kept in their position during the foaming of the foam in the intermediate space by means of the press under a predetermined pressure. Particularly preferably, it is provided that the cover plates are glued together by means of the curing of the foam. Alternatively, it would also be conceivable to glue the foam in the already cured state with the cover plates. The heat exchanger tube can already be placed between the cover plates with the surface area (s) adapted to the cover plate in its or its shape. Alternatively or additionally, it is also possible to transform the heat exchanger tube to form the or in its shape adapted to the cover plate surface area or surface areas when squeezing the cover plates with the press.
    Further features and details of preferred embodiments of a heat exchanger device according to the invention and also of a production method according to the invention are explained below with reference to the description of the figures. Show it:
    1 shows an exploded view of a first embodiment of a heat exchanger device according to the invention;
    2 to 5 are sectional views of the first embodiment according to the invention of a heat exchanger device and its production;
    6 to 9, a second embodiment of a heat exchanger device according to the invention as well as various steps for their preparation also in a vertical section.
    Fig. 1 shows an exploded view of the first cover plate 2 and the second cover plate 3 with an interposed, here meandering, formed heat exchanger tube 4, which has the pipe wall 5. The heat exchanger tube 4 is elongated apart from the bent portions of the meander in the longitudinal direction 8. Fig. 2 shows a vertical section in a sectional plane orthogonal to the longitudinal extent 8. The other Figs. 3 to 9 each show vertical sections in such a sectional plane. In Fig. 2, the folded edges 13 of the first cover plate 2 and the second cover plate 3 are first good to see, which close the gap 11 between the cover plates 2 and 3 in the assembled state laterally and limit. In the first embodiment shown here according to FIGS. 2 to 5, the sides 6 of the tube wall 5 which respectively face the cover plates 2 and 3 are provided with a surface region 7 adapted in their shape to the cover plates 2 and 3. In the finished heat exchanger device 1, these adapted surface regions 7 are in each case lying flatly and directly against the cover plates 2 and 3, as is known e.g. in Fig. 5 is clearly visible. In the first exemplary embodiment according to FIGS. 2 to 5 shown here, these adapted surface regions 7 of the tube wall 5 are each of planar design. This corresponds to the shape of the cover plate 2 in the areas where these adapted surface areas 7 of the tube wall 5 abut. This ensures that the adapted surface areas 7 of the Rohnwandung and the respective cover plates 2 and 3 each lie flat against each other. The width 9 of these adapted surface regions 7 is, as already explained, advantageously at least 25%, preferably at least 50%, of the total width 10 of the raw wall 5. Outside the adapted, here flat surface regions 7, the tube wall 5 can be any, e.g. as curved shapes have here. But there are also square or otherwise shaped cross-sections of the heat exchanger tubes 4 and 5 of the Rohnwandung conceivable. In Fig. 3, the heat exchanger tube 4 is already placed between the two cover plates 2 and 3. With the press 14 and the press upper part 15 and the press bottom part 16, the cover plates 2 and 3 are compressed. The spacers 17 give it
    Distance of the cover plates 2 and 3 before and prevent the two cover plates 2 and 3 are compressed too far. The flanks 13 close the intermediate space 11, which extends between the two cover plates 2 and 3 and outside of the heat exchanger tubes 4, laterally outwards.
    The inventive method now provides that in this compressed state shown in FIG. 3 foam for forming the foam body 12 is introduced into the intermediate space 11 between the cover plates 2 and 3 in the area outside of the heat exchanger tube 4 and cures there. The press 14 with its upper press part 15 and its lower press part 16 can support the cover plates 2 and 3 and provide them with a certain bias toward each other. This also ensures that the distance between the cover plates 2 and 3 in the final product has the desired value. While in Fig. 3, the gap 11 is still shown so empty before the introduction of the foam, Fig. 4 shows the state in which the foam body 12, the gap 11 outside of the heat exchanger tube 4 but within the cover plates 2 and 3 and the flanks 13 given external borders fills. After curing, the press 14 can be opened and the finished heat exchanger device 1 can be removed from the region between the upper press part 15 and the lower press part 16. Fig. 5 shows, as I said, a cross section orthogonal to the longitudinal extent 8 of the heat exchanger tubes 4 through the finished end product in the form of the heat exchanger device 1 according to the invention of the first embodiment.
    FIGS. 6 to 9 now show analogous representations to FIGS. 2 to 5, although a second exemplary embodiment according to the invention is shown. While in the first embodiment, the heat exchanger tube 4 rests on opposite sides 6 each with the adapted in shape surfaces 7 on each of the two cover plates 2 and 3, is achieved in the second embodiment by means of an intermediate layer 18, that the heat exchanger tube 4 only on one side 6 abuts against the second cover plate 3, while between the first cover plate 2 and the heat exchanger tube 4, the intermediate layer 18 is located. The intermediate layer 18 can, as shown here e.g. be latticed, but also designed differently. It may be heat-insulating but also thermally conductive. This can be selected according to the application of the heat exchanger device 1 according to the invention. Apart from this mentioned difference, the second exemplary embodiment according to FIGS. 6 to 9 substantially corresponds to the first exemplary embodiment according to FIGS. 2 to 5, so that reference is made to the above details for further details of this heat exchanger device 1 according to the invention and also the method for its production can. 9 again shows a vertical section through the finished product, ie the heat exchanger device 1 according to the second embodiment of the invention.
