Description

Guide plate assembly for a heat exchanger, heat exchanger, method of manufacturing a heat exchanger and kit for retrofitting or retrofitting a heat exchanger. FIELD OF THE INVENTION

The present invention relates to a Leitscheibenanordnung for a heat exchanger, a heat exchanger, in particular using the Leitscheibenanordnung invention, a method for producing a heat exchanger and a Ausrüstkit or for a heat exchanger. In particular, the present invention relates to a Leitscheibengerüst or Leitscheiben system for a block heat exchanger.

INTERGRUN D OF THE INVENTORY

In process engineering, and in particular in chemical engineering, heat exchangers are used for controlling the temperature of fluid media, be they essentially liquid or gaseous. In particular, these may be so-called block heat exchangers which consist of a heat exchanger core and a jacket surrounding the core, the core having two types of bores, so-called longitudinal bores or vertical bores and so-called transverse bores, radial or horizontal bores. In this case, the holes of the first type extend essentially in a first direction, for example in a longitudinal or extension direction Z of the heat exchanger core, and measure it completely. The holes of the second type run substantially perpendicular to the direction Z of the bore of the first type and also completely through the heat exchanger core, but in a transverse or radial direction. The holes of the first type and the second type do not communicate with each other. In operation, the holes of the first kind are separated from a first d ium, usually by a produc tion or process med iu m, which is to temper, flows through. The bores of the second type are flowed through by a second medium, often the service medium, which discharges or absorbs heat to and from the process fluid.

Often, the design of the geometry of the jacket, which encloses the heat exchanger core, as well as the provision of a so-called guide disk system or Leitscheibengerüsts, which are generally referred to below as Leitscheibenanordnung, generates a cross counterflow of the two media in relation to each other. In this case, between the jacket and the heat exchanger core a jacket area or jacket space is formed, which is hermetically sealed relative to the holes of the first kind and with respect to the Med ium, which flows in these holes of the first kind.

The Leitscheibenanordnung is essenl in this iesem mantle space arranged and consists of Leitscheiben to the vertical subdivision ung the mantle space in übereinander sen krecht arranged compartments or vol umwenschnschnte as well as two or more longitudinal strips to the horizontal lower part of the sen krecht arranged compartments of the cloak room. Through a vertically cascaded offset arrangement of the guide disks, a cascade-shaped or terraced course of the flow for the second medium through the heat exchanger core is produced in cooperation with the holes of the second type.

The cross-countercurrent process results in particularly intimate thermal exchange of the first and second media without allowing this direct mechanical contact with one another. It is also important that the material of the heat exchanger core has a particularly high thermal conductivity. Graphite cores or graphite-based cores can be used here. However, other materials are also conceivable, but in each case the properties of the heat-exchanging media may have to be taken into account, eg with regard to their abrasiveness, their chemical aggressiveness, their temperature and other parameters that meet the requirements of the material structure of the heat exchanger core and also of the jacket and define the guide plates and the longitudinal strips.

A problem with known Leitscheibenanordnungen is that they must be mounted in the construction of a block heat exchanger with considerable effort on the heat exchanger core and then surrounded by the jacket. Since typical heat exchangers may reach a height of several meters in order to meet the throughput and heat exchange efficiency requirements, provision must be made after assembly of the idler stand consisting of the idlers and the sills to substantially form the finished idler stand on the heat exchanger core surrounding, to install. As a rule, several persons and often also corresponding lifting devices, e.g. Cranes or the like, necessary. In addition, a considerable amount of time is necessary because when attaching the Leitscheibengerüsts existing heat exchanger core damage to the core itself and the framework of the Leitscheibenanordnung must be avoided, so that a robust handling when attaching the Leitscheibengerüsts on the heat exchanger core usually forbids.

SUMMARY OF THE INVENTION It is the object of the invention to provide a guide disk arrangement for a heat exchanger core, a heat exchanger, a method for producing provide a heat exchanger and a replacement or retrofit kit for a heat exchanger specify, in which the assembly of the guide plate assembly in a particularly simple and nevertheless reliable manner with a possible least expenditure of time, personnel and Zusatzatinrich- lines can be achieved.

The object underlying the invention is achieved in a Leitscheibenanordnung according to the invention with the features of independent claim 1. Further, a heat exchanger, a method for producing a heat exchanger and a retrofit kit for a heat exchanger in the claims 14, 1 5 and 17 are defined to solve the problem. Advantageous developments are the subject matter of the dependent claims.

The present invention provides a guide disk arrangement for a heat exchanger, in which a plurality of guide disks is provided, which are for guiding a in an associated heat exchanger, in the heat exchanger core of the associated heat exchanger and in the jacket region of the associated heat exchanger between the heat exchanger core and a heat exchanger core surrounding jacket of Heat exchanger in the Kreuzge- genstromverfahren flowing medium is formed. According to the invention, a respective respective guide disk of the guide disk system is designed to be plugged on the heat exchanger core of the associated heat exchanger.

This means that contrary to the previous procedure, for example, after the Leitscheibenanordnung is preassembled as a Leitscheibengerüst, then after the pre-assembly with relatively high effort and possibly with the help of mechanical help, eg by using a crane, must be placed over the heat exchanger core of the associated heat exchanger, According to the invention, the guide disk arrangement can be formed simply by virtue of the fact that the individual guide disks of the guide disk arrangement are located at a corresponding position on the heat exchanger core of the guide disk assembly. ordered heat exchanger are infected. In this way, it is possible to reliably, without great personnel expenditure and without the need for mechanical assistance, to design the guide disk arrangement necessary for a heat exchanger by simply attaching the guide disks.

It is particularly advantageous if the respective ige Leitscheibe is formed for releasable attachment to the heat exchanger core of the associated heat exchanger. Then there is also the possibility of exchanging individual guide disks of the guide disk arrangement or also the entire guide disk arrangement, e.g. during maintenance or cleaning work or when a defect occurs.

A respective guide plate can be formed in a plane or extension plane XY in a plate-like and planar manner with an upper side and a lower side in or parallel to the plane XY and have a region with a concave inner contour in or parallel to the plane XY.

The concave inner contour can be adapted in the shape and course of an outer contour, in particular convex, of a heat exchanger core of an associated predetermined heat exchanger and, in particular, be formed in a manner complementary to the shape and course of the outer contour of the associated heat exchanger core. In this way, the guide disks of the Leitscheibensystems optimally adapted to the flow of the contour - ie the shape and geometry of the heat exchanger core of the associated heat exchanger.

A respective guide disk can have one or more first attachment means for attachment to the heat exchanger core of an associated heat exchanger. sen. This allows a particularly simple, but secure fastening when plugged into the heat exchanger core of the associated heat exchanger.

The one or more first attachment means can preferably be formed on the underside of a respective guide disk and additionally or alternatively of a long shape along or parallel to an extension direction Y. As a result, the respective guide disk is suitable for being connected to the attachment means n z. B. to be introduced into associated service bores of the heat exchanger core of the associated heat exchanger. The service bores on the heat exchanger core of the associated heat exchanger are present in any case and can therefore be used to connect the guide disks of the guide disk arrangement, so that no additional measures must be taken on the heat exchanger core in order to secure the guide disks.

Therefore, it may also be possible to retrofit existing heat exchangers.

In addition, in the manufacture of the entire heat exchanger, modification of the heat exchanger core may be dispensed with, because the guide plates of the guide plate assembly are provided as such with all means for securing by plugging on the conventional heat exchanger core. Thus, it is also possible to use conventional heat exchanger cores.

The one or more first Ansteckm ittel may be the same or the same acting, in particular as or m with identical pins or tubes or by other elements of Längl I extended shape. The provision of several attachment means for a respective guide disc increases the stability of each individual guide disc in the condition affixed to the heat exchanger core. In addition, the provision of pens or tubes forms a particularly simple measure, without the formation of compl ized mechanisms would be necessary.

If tubes are provided as clip-on means, it also results that the service bores of the heat exchanger core of the associated heat exchanger which are respectively used for attaching the guide plate are not completely closed, but can also make their contribution to the heat exchange between the service medium and the process medium.

A respective pin or a respective tube may be formed in its outer contour perpendicular to its extension direction Y in its outer contour corresponding to an inner contour of a service bore of the heat exchanger core of the predetermined associated heat exchanger. This measure ensures a particularly secure hold of the Ansteckmittels in the service hole and thus a secure fit of a respective Leitscheibe the heat exchanger core of the associated heat exchanger. A respective baffle may have an open shape, e.g. in the form of a section of a ring shape and in particular a half-ring shape having a first end and a second end, in particular each based on a circle, an ell ipse, a rectangle, a square or an N-corner, preferably of uniform shape. By a corresponding selection of the shape, a particularly intimate contact of the inner contour of a respective guide disk with the outer contour of a respective heat exchanger core of the associated heat exchanger is ensured.

Two or more vertical strips may be formed, which serve for the lateral boundary of the jacket region of the heat exchanger and for arrangement on the heat exchanger core of the assigned predetermined heat exchanger. shear on its outer contour and perpendicular to the extension plane XY of a respective baffle are designed to extend and are in contact with the first and second ends of a respective baffle. The vertical strips on the one hand subdivide the jacket region or jacket space laterally into corresponding volume sections and correspondingly provide the guide disks of the guide disk assembly with lateral support for their attachment to the heat exchanger core of the associated heat exchanger. This increases the stability of the Leitscheibenan- order.

A respective baffle may have second clip means at its first and second ends. The vertical strips may have recesses which are designed to receive the second attachment means and thus to contact the first and second ends of the guide disks.

These measures further increase the stability of the Leitscheibenanordnung in the infected state of the guide plates, since an additional possibility of contagion and support in a safe manner not only in the central area by the first Ansteckmittel but also in the peripheral area by the second Ansteckmittel on the vertical bar are possible , There may be two vertical strips in the extension direction Z of the associated heat exchanger core of an associated heat exchanger can be provided.

A plurality of guide disks in the extension direction Z of the heat exchanger core and thus of the vertical strips can be arranged alternately and cascade-like on both sides of the vertical strips. These measures ensure, in connection with the geometry of the heat exchanger core of the associated heat exchanger, the formation of a cross countercurrent process. The guide disks and / or the vertical strips can be wholly or partially formed with or from one or more materials from the group of materials which is formed from steel, stainless steel, tantalum, zirconium, plastics, in particular PTFE, PP, PE, PA6 , PA66, etc., PVDF, graphite, especially in non-impregnated form, and CFC materials. These measures ensure optimum selection and adaptation of the material properties to the thermal, mechanical and chemical stresses which occur on the guide disk arrangement when used in the assigned heat exchanger. The vertical strip can be subdivided in the extension direction Z in each case in the manner of a plug-in system into mutually releasably fastened to each other vertical subsections and so be adjustable in their overall length. Thus, in a simple manner different heights of heat exchangers are taken into account.

Another aspect of the present invention is to provide a heat exchanger and in particular a block heat exchanger having a heat exchanger core and a jacket surrounding the heat exchanger core such that a shell region or shell space is formed between the heat exchanger core and the shell, between the shell and the heat exchanger core is a Leitscheibenanordnung invention for guiding a flowing in the heat exchanger, in the heat exchanger core and in the shell region or shell space in the cross-countercurrent flow medium formed. An additional aspect of the present invention is to specify a method for producing a heat exchanger, in which a guide disk arrangement according to the invention is formed on an intended heat exchanger core of a heat exchanger by attaching the plurality of guide disks to the heat exchanger core.

In the case of an existing heat exchanger, an existing conventional guide disk arrangement can be removed before the guide disks of the guide disk arrangement according to the invention are plugged. In this case, the possibility of retrofitting an existing heat exchanger with the novel guide disk arrangement is offered.

Schl ießl I provides the present invention also an equipment or retrofit kit for a heat exchanger, consisting of a plurality of Leitschei- ben and vertical strips to form a Leitscheibenanordnung invention to a heat exchanger core of an associated heat exchanger.

These and other aspects of the invention will be discussed again below in other words:

In particular, the invention relates to a new washer system for block heat exchangers. The conventional or standard diffuser framework, for example, for cylindrical block heat exchangers made of graphite is complex. It consists of a variety of D components. The arrangement is relatively expensive, difficult to assemble and can only be standardized to a limited extent. Among other things, these disadvantages are avoided by the invention of the disc system presented here. One embodiment of the new diaphragm system consists of two components, the diaphragm segment or the guide plate and a vertical strip or mounting strip. Both the diaphragm segment and the mounting bar guide the medium through the service bores of the D BIock. The Leitscheibensegmente be connected for example by connectors to the block of the heat exchanger core and in particular with the mounting bar. On each segment, for example, one or two solid or hollow cylinders can be attached, which can be plugged into the service bores of the blocks.

The fastening strip can be designed in variable length. It can also be extended and / or by a plug-in system.

The diaphragm segments and / or the fastening strips can be made of a wide variety of materials (eg carbon steel, stainless steel, special metals, PTFE, PP, PE, PA6, PAG6 or other plastics). The new diaphragm system has the following advantages in particular:

1 . ) It is simple and robust.

2.) It can be standardized and thus leads to a cost reduction.

3.) It is easy to assemble, disassemble and maintain, ie. it creates customer or competitive advantage

4.) It can be produced by mass production, this also leads to a cost reduction

DETAILED DESCRIPTION OF THE EMBODIMENTS

Hereinafter, embodiments of the present invention will be described. All embodiments of the invention as well as their technical features and properties can be individually isolated or optionally combined with one another and combined without restriction. Structurally and / or functionally identical, similar or identically acting features or elements are referred to below in connection with the figures with the same reference numerals. Not always will a detailed description of these features or elements be repeated.

First of all, reference is made to the drawings in general. First of all, the basic structure and the functional principle of a block heat exchanger and of the associated windscreen system are discussed, in particular with reference to FIGS. 1 and 3A to 4D, from which emerge in particular the flow conditions in the heat exchangers discussed here.

The standing in connection with the Leitscheiben system 40 according to the invention heat exchanger 1 0 are generally addressed as a block heat exchanger 1 0 and have, inter alia, a heat exchanger core 20 made of a material particularly suitable for the heat transfer material, for. made of graphite. Such block heat exchangers 10 are frequently used in the chemical industry and process engineering, in particular when heat exchange processes are to be carried out in connection with corrosive media. Usually, process media or product media which are to be subjected to a heat treatment are distinguished from so-called service media, which serve as heat source or sink in the heat treatment step or tempering step. These product or process media on the one hand and the service media on the other hand are guided through a corresponding heat exchanger 10 in a so-called cross countercurrent flow without direct contact with one another.

On a base plate 14, for example, cylindrical block modules 1 are arranged concentrically above one another inside a jacket 30 and accordingly form the heat exchanger core 20 of the heat exchanger 1 0 as a whole. The heat exchanger core 20 and consequently the block block Modules 1 have along their extension direction Z longitudinal bores 2 or longitudinal channels 2, which, if individual modules 1 are provided, communicate across modules. In this respect, the modules 1 are constructed approximately the same.

Substantially perpendicular to these longitudinal channels 2 transverse channels 4 are provided, which are also referred to as service holes 4, with the

Do not communicate longitudinal bores 2, but only volume sections or compartments connect the shell region or shell space 30 'on opposite sides of the shell 30.

Through the longitudinal channels 2, the first medium M1 usually flows through the process medium or product medium which is to be subjected to a thermal treatment, be it heating or cooling. Through the transverse channels 4 then flows as a second medium M2, the service medium, which serves to heat or heat the product or process medium M 1.

The transverse channels 4, which are arranged in superimposed planes and adjacent rows parallel to each other, open, as already mentioned above, in the shell region or shell space 30 'between the shell 30 and the heat exchanger core 20th

The jacket region 30 'or jacket space 30' is subdivided by a Leitscheibenan- order 40 into individual sections, volume sections or compartments. In each case, transverse channels 4 open into these volume sections of the jacket space 30 '. Each volume portion of the shell space 30 'extends over a plurality of rows and levels of transverse channels 4. In operation, the service medium M2 passes through an inlet 9 provided laterally in the shell, in FIG. 1 at the lower end of the heat exchanger 20 of outside in the shell space 30 'and there filled in operation, first a first volume portion which is bounded by a portion of the Leitscheibenanordnung 40. The Leitscheibenanordnung 40 prevents by its geometry a further flow of the service medium in the shell space 30 '. As a result of the selected arrangement of the guide disks 50 and the provided vertical strips 60 of the guide disk arrangement 40, the service medium M2 is deflected into the transverse channels 4 opening into this volume section and thus from a vertical flow direction in the direction Z into a flow direction extending transversely thereto along the extension direction Y. , After flowing through the first group of transverse channels 4 in this volume section, the service medium M2 then passes into the first opposing volume section of the jacket space 30 '. There, it is again deflected by the selected geometry of the Leitscheibenanordnung 40 and forced to flow through a next group in this volume section of einenterender transverse channels 4 in the horizontal opposite direction.

In this way, a cascade-like movement of the flow of the service medium M2 is formed, alternately taking place in the volume sections of the shell space 30 'a vertical flow direction parallel to the direction Z and alternately between a horizontal flow direction parallel to the direction Y in the transverse channels 4.

In this way, the service medium M2 as it flows through the jacket space 30 'and the transverse channels 4 of the heat exchanger core 20, the entire heat exchanger core 20 from the service medium, in FIG. 1 from bottom to top and alternately from right to left and from left to right, flows through and thereby redirected several times such that product medium M1 and M2 service medium almost cross several times and in an intense heat exchange, mediated by the material of the heat exchanger core 20 advised. At the upper end of the heat exchanger 10, the service medium M2 leaves the jacket space 30 'by means of an outlet 8 for the service medium M2 which is again provided laterally. Instead of the terms product or process medium M1 and service medium M2, it is also generally possible to speak of a first medium M1 and a second medium M2. Although the respective roles are usually assigned in the manner described above, this is not absolutely necessary.

For the inflow E and the outflow A of the first or process medium M1, the process bores 2 or longitudinal channels 2 in an upper and in a lower head piece 5o or 5u are merged into respective chambers.

The flow directions of the media M1 and M2 can also be reversed, in which case the corresponding functions of the inlets 8 and 9 and the corresponding chambers are interchanged. However, it is crucial that the two media M1 and M2 are conducted in countercurrent to each other, so that cold and hot medium are not introduced from the same side in the heat exchanger 1 0. This would be detrimental to the heat exchange efficiency and, in addition, possibly lead to high temperature differences in the coming into contact with the media M1 and M2 in contact materials.

The head pieces 5u and 5o may also be formed with a plurality of sub-chambers.

Depending on the embodiment and geometry, in particular in the case of modular construction, joints between block modules 1 arranged one above the other can be arranged. occur, which may optionally be partially or completely closed with seals 3, for example made of PTFE.

The jacket area 30 'or space 30' with the actual jacket 30 is anchored over or on the base plate 14. For sealing between the base plate 14 and the lower head piece 5u, a flat gasket 1 5 or round seal 1 5 may be provided. This can e.g. consist of an elastomer.

For further sealing, a tension can be applied (for example via the upper head piece 5o), while the actual jacket 30 is freely movable downwards through the round seal 15 and sealed off at the upper head piece 5o by a further round seal. About helical springs a tension is formed, which also takes into account the different thermal expansion of the different materials and compensates.

All these aspects are particularly in connection with the FIG. 1, but also in connection with the other figures, in particular FIGS. 3A to 4D recognizable.

FIG. 1 also shows the vertical strips 60 or 60-1 and 60-2, on which, in addition to the fastening of the guide disks 50 directly by attachment to the heat exchanger core 20, the guide disks 50 also have their first and second ends 53-5. 1 and 53-2 are mounted in order, in cooperation with the vertical strips 60, 60-1, 60-2, to subdivide the jacket space 30 'into volume sections, in alternating cascading form for realizing the cross-countercurrent flow between the two media M 1 and M2.

In the Fig. 1, the heat exchanger core 20 has the shape of a vertical circular cylinder. However, other basic forms are conceivable. The holes or channels 2 for the product or process medium M1 run perpendicular in the FIG. 1 and thus parallel to the axis of symmetry or extension axis Z of the underlying basic body for the heat exchanger core 1 0, näml I the vertical Kreiszyl inder. Fig. 2 is a schematic and perspective side view of a portion of a heat exchanger core 20 of a heat exchanger 10 as described in connection with FIG. 1 has been described. This section can also be understood as a single block module 1, with a plurality of modules 1 connected vertically one behind the other in the extension direction Z then forming the entire heat exchanger core 20 of the associated heat exchanger 10.

This section or the module 1 already have corresponding guide plates 50, which are connected via first Ansteckmittel 54, which are arranged on the underside 50u of the respective guide disc 50 in the service holes 4, which can be understood as horizontal channels or holes, and on the other hand, are supported by their ends 53-1 and 53-2 and the second clip-on means 55 provided there on the recesses 62 of a provided vertical strip 60, 60-1, 60-2.

It can also be seen that the inner contour 50i of the respective guide disk 50 is adapted to the outer contour 20a of the heat exchanger core 20. In this case, the heat exchanger core 20 and its module 1 have the shape of a vertical circular cylinder with a symmetry axis Z, to which also the parallel vertical channels or holes 2 are formed for the process medium M1.

The outer contour 50a of the guide disk 50 extends concentrically to the inner contour 50i, ie it is also formed in a circular or annular shape on the basis of a circular shape, but the outer contour 50a can also have any other possible shape and, for example, an inner contour of the jacket 30 of a given order heat exchanger follow 1 0, even if this should not have a circular cylindrical shape.

The Fig. 3A to 3D show an embodiment of a heat exchanger 1 0 according to the invention using a Leitscheibenanordnung 40 according to the invention, wherein the heat exchanger 1 0 and the associated heat exchanger core 20 is again based on a vertical and kreiszyl indrische shape. The Fig. 3A and 3C are partially sectioned side views. The views of FIG. 3B and 3D are sectional plan views in a direction parallel to the extending direction Z of the heat exchanger. The respective sectional planes are references to the respective figures indicated by the axes A-A, B-B, C-C and D-D. 3A to 3D in which these sections are used.

The vertical profile of the heat exchanger 110 from the lower head region 5u to the outlet 7 and the outflow A for the first medium M1 or product medium M1 to the upper head region 5o with the inlet 6 and the inflow E for the first medium or product medium can be seen in each case M 1.

The outer shell is again formed by a jacket 30. The inner region is formed by the heat exchanger core 20, which extends as the heat exchanger 1 0 as a whole in the extension direction Z. The heat exchanger core 20 is formed in the extension direction Z with the vertical bores 2 or channels 2 for the first medium M1 or product medium M1.

Perpendicular to the extension direction Z and thus in the direction of extension Y, the heat exchanger core 20 horizontal channels 4 or holes 4, which are also referred to as service holes 4 and serve the transport of the second medium M2 or M2 service medium. This second medium or service medium M2 is introduced via a lower inlet 8 via an inlet e for the second medium M2 or service medium M2 and discharged via an outlet 9 provided in the upper area via the outflow a for the second medium M2 or service medium M2.

Due to the selected geometry, a jacket region or jacket space 30 'is formed between the heat exchanger core 20 and the jacket 30, in which second medium M2 or service medium M2 flows from below to above from the inlet 8 to the outlet 9.

In this case, the jacket region 30 'or jacket space 30' is subdivided into volume sections or compartments 31 by the intended guide disk arrangement 40, which is formed by the actual guide disks 50 and the vertical strips 60. Due to the selected alternating and cascading arrangement of the guide disks 50 with respect to the vertical strips 60 of the cross-countercurrent of the second medium M2 with respect to the first medium M1 is real isiert. This means that after the inflow of the second medium M2 through the inlet 8, the second medium M2 first flows through the service bores 4 from right to left from the first compartment into the second compartment, then fills up the second compartment, then from left to right again flows into the third compartment on the right, so that in such a cascaded course from top to bottom and from right to left or from left to right, all compartments of the shell space 30 'and the service holes 4 communicating with the compartments follow one another be flowed through until the second medium M2 appears at the outlet 9 provided above in the outflow a. During the flow of heat is exchanged relative to the first medium or product medium M 1, i. delivered or recorded. It can be seen in FIG. 3A the presence of the first Ansteckmittel 54 on the bottom 50u of the respective Leitscheiben 50. These first Ansteckmittel means 54 are introduced to a certain depth in the service holes 4, sitting there fitting and support the guide plates 50 in the guide plate assembly 40. In the FIG. 3C, moreover, the first and second ends 53-1 and 53-2 of the respective guide plate 50 formed as a plate 53 are received in recesses 62 of the vertical strip 60. Thus, the foremost region of the first and second ends 53-1 and 53-2 of the guide plates 50 designed as plates 53 forms a second attachment means 55, which is accommodated in the respective recesses 62 of the vertical strips 60 and the peripheral support of the guide disks 50 in the jacket region 30 'serves.

The Fig. 4A to 4D show - similar to FIG. 3A to 3D - a modified form of a heat exchanger 1 0 according to the invention with the Leitscheibenanordnung 40 according to the invention, with an otherwise analog structure and the same function, however, a cuboid base body is provided both for the heat exchanger core 20 and for the jacket 30. Accordingly, as shown in FIGS. 4B and 4D, the guide disks 50 are adapted in their open shape and thus their inner contour 50i of the cuboid shape and thus have a polygonal course, which follows the outer contour 20a of the heat exchanger core 20 and the inner contour of the jacket 30. The Fig. FIGS. 5A to 7E show various embodiments of guide disks 50 for the guide disk assembly 40 according to the invention, each of which has the form of plates 53.

In Embodiments 5A to 6E, the idlers 50 and the underlying plates 53 are in the shape of a ring portion or a ring portion based on a circular shape. Such guide disks 50 can For example, in the embodiments for the heat exchanger 1 0, which in Figs. 1 to 3D are used.
