Description

Cavity X MIXER heat exchanger

Field of the invention

The present invention relates to a mixer-heat exchanger, and a mixer-heat exchanger insert assembly for a mixer-heat exchanger, in particular a mixer-heat exchanger and a mixer-heat exchanger insert arrangement with a reduced fouling behavior.

Background of the invention

For the mixing of fluids, especially in processes, both static and dynamic mixers can be used. For dynamic mixers

For example, stirring elements are used which actively stir the fluid to be mixed. In a static mixer, the mixing does not take place by an externally introduced stirring energy, but by the energy inherent in a flowing fluid. In this case, the fluid is mixed by the movement of the fluid when hitting a mixer geometry. For such a mixing by means of a static mixer, for example, so-called X-mixers are used, in which in the flow volume

alternately arranged transversely to each other structures are introduced, the one

mix through fluid flowing through. Such so-called X-mixers can for example consist of a plurality of rod-shaped flat bodies, which are arranged, for example, alternately at an angle of, for example, 90 ° to each other. A fluid flowing through is thus divided several times and merged again, resulting in a laminar or turbulent flow, or forced to a change in direction, whereby a turbulent flow sets, which then leads to a mixing of the fluid. Since such mixers are often used in reactors, there is also the need not only to mix the fluid, but also to temper the fluid at the same time. For this purpose, mixer-heat exchangers are known, which consist of several tubes through which a temperature control can be performed. These tubes, which generally run in the longitudinal direction of a flow channel, are arranged transversely thereto

Flow baffles provided, which cause by "split and recombine" a mixing of the flowing fluid.

Furthermore, heat exchangers are known in which the tubes which guide a tempering fluid are guided meander-shaped, wherein the meandering guided tubes lie in a plane which are parallel to the flow direction of the fluid in a flow channel. The mixers and heat exchangers described above are known, for example, from EP 1 067 352 A2 or WO 2008/017571 A1.

The heat exchangers or mixers described above have only a small amount

Mixability or, in particular for fluids containing agglomerates, tend to accumulate agglomerates in areas of acute angles in which the agglomerates or thickened fluid clumps may seize or have flow-calmed areas in which side reactions may take place

Products can also deposit. This effect is called fouling.

Such fouling possibly has a negative influence on the state of the fluid to be mixed and tempered, so that the setting of agglomerates or thickened fluid lumps should be avoided.

Summary of the invention

It may be considered an object of the present invention to provide a mixer heat exchanger and a mixer-heat exchanger insert or a mixer-heat exchanger insert arrangement having a reduced fouling tendency.

The object of the present invention is solved by the subject matter of the independent claims, wherein developments of the invention are embodied in the dependent claims.

According to one embodiment of the invention, there is provided a mixer-heat exchanger insert comprising a first group of hollow body plates having an inner volume and a second group of hollow body plates having an inner volume

Hollow body plates of the first group are inclined relative to a longitudinal direction of the mixer-heat exchanger insert in a first direction, wherein the hollow body plates of the second group relative to a longitudinal direction of the mixer-heat exchanger insert are inclined in a second direction, wherein the hollow body plates of the first group laterally the second group of hollow body plates abut, and the inner volumes of the first hollow body plates are connected to the inner volumes of the second hollow body plates, such that the inner volumes of the first group and the inner volumes of the second group are part of a contiguous total internal volume which is configured as a tempering fluid respectively. In this way, a mixer-heat exchanger insert may be provided which as

Flow guiding at the same time also provides structures through which a Temperierungsfluid can be performed. In other words, the structures of the mixer heat exchanger serve Use at the same time as Strömungsleitstrukturen for homogenization and to guide a bath fluid. In particular, this eliminates one example

EP 1 067 352 A1 known mixing structure, in which provided in the longitudinal direction of a flow channel tubes for guiding a tempering fluid are provided, which are additionally interspersed with transverse thereto Strömungsleitblechen. In particular, it can be avoided that at the connection points between the flow channels of the

Temperierungsfluides and Strömungsumleitblechen agglomerates and thickened

Set fluid lumps, as it does not require such compounds in the mixer heat exchanger insert according to the invention. Such a mixer-heat exchanger (insert) or mixer-heat exchanger insert arrangement also have a much better

Surface to volume ratio, in comparison to those in EP 1 067 352 A1

described mixer heat exchangers. In particular, the surface-to-volume ratio of the arrangement according to the invention can be higher by a factor of four than in the arrangement described in EP 1 067 352 A1.

According to one embodiment of the invention, the first direction and the second direction are diametrically opposed.

In this way, in an alternating influx of hollow body plates, which are inclined in the first direction, and of hollow body plates, which are inclined in the second direction, a division of the fluid flow or a strong alternating

Flow diversion is caused, which leads to a good mixing.

According to one embodiment of the invention, the mixer-heat exchanger insert further comprises a Temperierungsfluideinlass and a Temperierungsfluidauslass, wherein a

Hollow body plate of the second group laterally abuts at least two hollow body plates of the first group and at the two joints the inner volume of the hollow body plate of the second group are connected to the volumes of the two adjacent hollow body plates of the first group such that a Temperierungsfluid of the

Temperierungsfluideinlass on the inner volume of a first hollow body plate of the first group in the inner volume of the hollow body plate of the second group and then on the inner volume of the second hollow body plate of the first group to the

Temperierungsfluidauslass flows. In this way, a structure can be provided in which the hollow body plates, which are mutually inclined in a first direction and a second direction, are alternately flowed through by the tempering liquid. In this way, in particular a good mixing can be achieved by the mutually inclined hollow body plates, said hollow body plates can also be sequentially flowed through by the Temperierungsflüssigkeit. It should be understood that the liquid region of the

Temperierungsfluides, which is guided through the individual hollow body plates, compared to an outdoor area in which a liquid to be tempered and mixed, is performed, hermetically sealed, so that there is no unwanted mixing of a liquid to be tempered and mixed with the Temperierungsflüssigkeit.

According to one embodiment of the invention, the hollow body plates of the first group and the hollow body plates of the second group are web-shaped, wherein a plurality of web-shaped hollow body plates of the first group in the longitudinal direction are arranged in parallel spaced side by side and a plurality of web-shaped

Hollow body plates of the second group are arranged in the longitudinal extension direction parallel spaced apart, wherein the parallel juxtaposed web-shaped hollow body plates of the first group and arranged in parallel side by side

web-shaped hollow body plates of the second group are arranged adjacent to each other in alternating juxtaposition and the inner volumes of the respective web-shaped

Hollow body plates are joined together at joints. In this way, a plurality of parallel flow channels for a

Tempering be provided in the hollow body plates, so that, for example, a Temperierungsflüssigkeit in the mixer-heat exchanger insert independently

can be guided by each other in the channels. In particular, two web-shaped hollow body plates may be inclined in a first direction and two web-shaped hollow body plates may be inclined in the second direction, and these may be arranged alternately to one another. It should be understood that, if only a single contiguous inner volume to be provided, the web-shaped hollow body plates may be connected to each other at all joints so that their inner volumes are connected to each other. By arranging a plurality of such combinations of web-shaped hollow body panels, a stack can be provided in which the web-shaped

Hollow body plates are arranged one behind the other in the flow direction.

According to one embodiment of the invention, the mixer-heat exchanger insert has a third group of hollow body plates, wherein the hollow body plates of the third group are inclined in a third direction with respect to a longitudinal direction of the mixer-heat exchanger insert, wherein the first direction, the second direction and the third direction are each arranged at an angle of 120 ° to each other.

In this way, a kind of propeller assembly arranged by the inclined

Hollow body plates are achieved, which ensures a particularly good mixing of

allow for tempering and mixing fluids.

According to one embodiment of the invention, the angle of inclination of the hollow body panels of the first group with respect to the longitudinal direction and the inclination angle of the

Hollow body plates of the second group with respect to the longitudinal direction of the same amount. In this way, a uniform arrangement of the obliquely to each other

Hollow body plates are achieved, which at regular intervals again and again

To cause flow deflection or division of the fluid to be tempered and mixed, so that results in a uniform alternating flow deflection or flow division by the coincident inclination angle in opposite directions.

According to one embodiment of the invention, the hollow body plates form over the

Longitudinal direction at least two fluidly separate parallel total volumes.

This can be achieved in particular in that the connections of the inner volumes of the hollow body plates of the first group and the hollow body plates of the second group are connected at some joints, while they remain separated at other locations, so that the two fluidly separate parallel total volumes form. Thereby, a mixer-heat exchanger insert can be provided, in which the temperature control liquid flows back through the one total volume over the other total volume, so that the inlet and the outlet of the temperature control liquid can be provided on the same side.

According to one embodiment of the invention, the hollow body panels of the first group with one another and the hollow body panels of the second group with one another

matching distance in the longitudinal direction of the mixer-heat exchanger insert on.

In this way, it can be achieved that the effective flow cross sections at the parallel interspaces are evenly configured with a flow in the longitudinal direction, so that no artificial bottlenecks occur in which possibly a congestion of a liquid to be tempered can occur. Such a stowage can, for example, lead to an agglomeration or thickening of a liquid to be tempered and mixed, which in turn can accelerate the fouling process.

According to one embodiment of the invention, the hollow body plates of the first group and the hollow body plates of the second group with respect to the longitudinal direction at an angle of 30 ° to 60 °, in particular at an angle between 40 ° and 50 ° inclined.

In this way, a good ratio can be set between shear behavior and flow-calmed areas, so that for the liquid to be tempered

adequate mixing is ensured. According to one embodiment of the invention, the mixer-heat exchanger insert is produced by a 3D-printing method, in particular by an additive manufacturing method, in particular by a direct-metal-melt-laser-method (DMLS). In this way, a mixer-heat exchanger insert can be made with a complex structure, the hollow body plates are connected at the joints so that the inner volumes of abutting hollow body plates are interconnected. By means of a 3D printing method, complicated production of the individual components and connection of the individual components, for example by soldering or welding, can be avoided so that a mixer-heat exchanger insert according to the invention can be produced efficiently and inexpensively.

According to one embodiment of the invention, there is provided a mixer-heat exchanger insert assembly having a plurality of mixer-heat exchanger inserts as described above, wherein the plurality of mixer-heat exchanger inserts are arranged one behind the other with respect to a longitudinal direction

Temperierungsfluidauslass a mixer-heat exchanger insert with a

Temperierungsfluideinlass an adjacent mixer heat exchanger insert is connected such that the inner volumes are connected at a boundary between two adjacent mixer heat exchanger inserts, so that a Temperierungsfluid can flow from a mixer-heat exchanger insert to an adjacent mixer-heat exchanger insert ,

In this way, several mixer heat exchanger inserts can be arranged modularly one behind the other. In particular, individual mixer heat exchanger inserts can be made and joined together modularly as needed. This joining can be done, for example, by a welding method, a soldering method or an adhesive method. This can be ensured at the same time that the corresponding

Temperierungsfluideinlässen and -auslässen no leaks occur to the outer volume in which is the temperature to be tempered and mixed fluid. However, it is also possible to print several mixer-heat exchanger inserts in one piece.

According to one embodiment of the invention, the successively arranged mixer heat exchanger inserts are rotationally offset with respect to the longitudinal direction, in particular offset by 90 °.

In this way it can be made possible that, despite a present laminar flow, the desired mixing of the fluid to be tempered and to be mixed is achieved by the staggered arrangement of the mixer-heat exchanger inserts and thus also of the hollow body plates or web-shaped hollow body plates. According to one embodiment of the invention, the hollow body plates form four fluid parallel separate total volumes over the longitudinal extension direction, wherein the parallel total volumes are connected at one end of the mixer-heat exchanger insert arrangement such that a first and a second of the total volumes parallel to each other of a Temperierungsflüssigkeit flows through and then a third and a fourth of the total volumes are flowed through parallel to each other and anti-parallel to the first and the second total volumes.

In this way it can be ensured that even with a mixer-heat exchanger insert arrangement consisting of a plurality of mixer-heat exchanger inserts, a temperature-control fluid inlet and a temperature-control fluid outlet on the same side

can be arranged, wherein the Temperierungsflüssigkeit with respect to the

Longitudinal direction and then back flow. According to one embodiment of the invention, there is provided a mixer-heat exchanger comprising a fluid carrying volume having a fluid inlet and a fluid outlet, and a mixer-heat exchanger insert as described above or a mixer-heat exchanger insert assembly as described above, wherein the mixer Extends the heat exchanger insert or the mixer-heat exchanger insert arrangement in the fluid-carrying volume, so that a through the fluid inlet into the fluid-carrying

Volume inflow fluid is sheared by the geometry of the mixer-heat exchanger insert or mixer-heat exchanger insert assembly before the infiltrated fluid exits the fluid carrying volume through the fluid outlet. In this way, a mixer-heat exchanger can be provided, which ensures a reliable temperature control of a fluid to be mixed and tempered, and at the same time allows a sufficient mixing of the fluid.

According to one embodiment of the invention, the fluid-carrying volume over the

Longitudinal direction on a constant clear cross-sectional area.

In this way, dead and storage spaces can be avoided and a mixer-heat exchanger insert arrangement in the longitudinal direction in the fluid-carrying volume for

Assembly are inserted. Constant cross-section means that the volume without a mixer-heat exchanger insert used has a cross-sectional area which does not change over a longitudinal extent. However, an inserted mixer-heat exchanger insert can lead to effective flow cross-sections, which are no longer necessarily constant over the longitudinal extent. According to one embodiment of the invention, an envelope of the mixer-heat exchanger insert as described above has a cross-sectional area which is the corresponds to constant clear cross-sectional area of the fluid-carrying volume of the mixer-heat exchanger, in which the mixer-heat exchanger insert is to be introduced.

In this way, an accurate fit of fluid volume and mixer heat exchanger insert arrangement can be achieved. Extensive void volumes that are parallel to the mixer-heat exchanger insert arrangement can also be avoided.

Of course, the individual features described above may also be combined with each other, which may also result in some beneficial effects that go beyond the sum of the individual effects.

These and other aspects of the present invention are illustrated and clarified by reference to the exemplary embodiments hereinafter described.

Detailed description of exemplary embodiments

Figure 1 shows a mixer-heat exchanger insert 1 according to an exemplary

Embodiment of the invention. The mixer-heat exchanger insert, hereinafter also referred to as insert, has in the embodiment shown here a plurality of

Hollow body plates 10, 1 1 of a first group and a plurality of hollow body plates 20, 21 of a second group. The hollow body plates of the first group are inclined in one direction while the hollow body plates of the second group are inclined in an opposite direction. In the embodiment of FIG. 1 shown here, the direction of inclination of the hollow body plates is opposite and the angle of inclination is substantially the same. The different hollow body plates, which lie obliquely in the longitudinal direction L, here for example the hollow body plates 1 1, have a matching distance on. However, it should be understood that the hollow body panels according to other embodiments may also have different angles of inclination and possibly also may have a varying distance. All shown in the figures

Embodiments have hollow body plates that are substantially planar

Have on the flow surface. However, it should be understood that the hollow body panels can also be designed bent, which can set more optimized flow conditions, which can then lead to improved mixing.

In FIG. 1 it can be seen that the first group is the one below the other

Hollow body plates 10 and the respective underlying hollow body plates 1 1, while the second group has the underlying hollow body plates 20 and the respective underlying hollow body plates 21. The hollow body plates of the first group and the hollow body plates of the second group are each arranged alternately, so that there is a cross-shaped arrangement of the hollow body plates. The hollow body plates each have an inner volume, which, however, due to the closed

Representation in Figure 1 is not visible.

Figure 2 shows a partial sectional view of a mixer-heat exchanger insert according to an exemplary embodiment of the invention. In Figure 2 can be seen through the sectional view that the individual hollow body plates have an inner volume. In this case, in the embodiment shown in FIG. 2, the inner volumes 13 of the hollow body plates of the first group 10 or 11 are connected at the joints of the hollow body plates to an inner volume 23 of the hollow body plates 21, 20 of the second group, so that a temperature control fluid from the first group Hollow body plate 10 and 1 1 can flow through the connection at the joints of the first volume 13 in the second volume 23 of the second hollow body plates 20 and 21, respectively. In the embodiment shown in Figure 2, this results in an arrangement in which arise at least two separate channels, which can be flowed through separately. In addition, FIG. 2 shows at the upper end of the mixer-heat exchanger insert a temperature-regulating fluid inlet 110a and a temperature-regulating fluid outlet 120a. In the arrangement shown in FIG. 2, for example, a tempering fluid flows through the tempering fluid inlet 110a into the inner volumes of the hollow body plates 10 and 21, thereby flowing downwards opposite to the arrow of the longitudinal extension direction. At the end of the mixer-heat exchanger insert not shown here, the tempering liquid can then be deflected into the second channel strand, so that the tempering through the inner volumes 13, 23 of the hollow body plates 20 and 1 1 back up, here in the arrow direction of the longitudinal axis and flows exits through the Temperierungsfluidauslass 120a. In this way, a heat exchanger

are provided, which also allows mixing of a fluid to be tempered and mixed due to its design of the heat exchanger hollow body. Functionally matching, the arrangement can also be considered as a mixer, which by the

Hollow plate design of the mixer structures has a heat exchanger property. Figure 3 shows an exemplary embodiment of a mixer-heat exchanger insert 1, which has a plurality of hollow body plates. The hollow body plates of the first group 1 1, 1 1 a, 1 1 b are arranged one above the other, as well as the hollow body plates 10 and 10b and, analogously, the hollow body plates 20 and 21st Here it should be understood that "one above the other" also means "diagonally one above the other". The mixer-heat exchanger insert shown in Figure 3 is provided in a so-called single-channel arrangement, that is, the inner volumes of all the hollow body plates represent an entire inner volume, so that starting from the Temperierungsfluideinlass 1 10a a single flow channel through the mixer heat exchanger Use 1 results and the Temperierungsflüssigkeit by the

Temperierungsfluidauslass 120a can flow out. It should be understood that branches can also occur in the individual channel, which need not necessarily be dead-end free.

FIG. 4 shows a further exemplary embodiment of a mixer-heat exchanger insert 1, which, however, is embodied here in a so-called four-channel arrangement. In this case, the hollow body plates 10, 1 1, 20, 21 are connected to each other at the respective connection points such that their inner volumes do not represent a single internal volume, but a total of four internal volumes. This can be done, for example, by a nested

Arrangement of the flow-through hollow body plates can be achieved, so that, for example, every second of the hollow body plates 1 1 and every second of the hollow body plates 20 form a first channel, and the intermediate hollow body plates 1 1 and 20 can form a nested second channel. In the same way, every second of the hollow body plates 10 and every second of the hollow body plates 21 forms a channel, while also the intermediate hollow body plates 10 and 21 form a further channel, so that a total of four channels are provided. These channels can be arranged to each other that a

Temperierungsfluid can flow, for example, by a Temperierungsfluideinlass 1 10a, then distributed to the first two channels, in which the Temperierungsfluid moves against the fall direction of the longitudinal direction L down, while the Temperierungsfluid can be deflected down so that it through the two other channels flows back up and exits through the Temperierungsfluidauslass 120a.

Figure 5 shows a side view of a mixer-heat exchanger insert assembly 100 according to an exemplary embodiment of the invention. The mixer-heat exchanger insert arrangement, hereinafter also referred to as arrangement, has a plurality of

successively arranged inserts 1 a, 1 b on. These inserts 1 a, 1 b are arranged one behind the other in the longitudinal direction L. As can be seen from FIG. 5, the inserts are each offset by 90.degree. To one another, that is to say they are arranged rotated through 90.degree. About the longitudinal direction L one behind the other. Here are the designated here, but not visible in detail

Temperierungsfluidauslässe 120 a of a first insert 1 a with the

Temperierungsfluideinlässen 1 10b of a second insert 1 b connected so that a continuous or two or four continuous channels result through the arrangement. FIG. 6 shows a sectional view of the arrangement shown in FIG. 5, from which the position of the inner volumes of the individual hollow body panels can be seen. The scale shown in Figure 6 corresponds substantially to the scale of Figure 5. The mixer-heat exchanger inserts 1, 1 a and 1, 1 b are arranged one behind the other in the longitudinal direction L and also in Figure 6 by 90 ° to each other around the Longitudinal axis L twisted.

FIG. 7 shows a schematic view of the arrangement shown in FIG. 5 with a plurality of inserts 1 arranged one behind the other in the longitudinal direction L. By way of example, the arrangement of the hollow-body plates numbered with the hollow-body plates 10, 11 of the first group and the hollow-body plates 20, 21 of the second group is for use of the arrangement 100. Further, by the reference numerals A and B, the position of the inclinations of

Hollow body plates specified. It can be seen from FIG. 7 that the inclination directions A and B are diametrically opposed, the hollow body plates of the respective groups have substantially matching distances, and the inclination angles of the hollow body plates of the respective group coincide.

FIG. 8 shows an exemplary embodiment of a mixer-heat exchanger 200 with a fluid-carrying volume 230 and a fluid inlet 210 and a fluid outlet 220. It should be understood that the mixer-heat exchanger 200 both in the arrow direction of

Longitudinal direction L can be flowed through, as well as in the opposite direction, whereby then from the fluid inlet of the fluid outlet, and from the fluid outlet of the

Fluid inlet is. The mixer-heat exchanger insert arrangement used in Figure 8 substantially corresponds to the above-described arrangement. In the arrangement described in FIG. 8, a tempering fluid inlet 110 is located on the side of the fluid inlet 210, while the tempering fluid outlet 120 is located on the side of the fluid outlet 220. In the arrangement shown in FIG. 8, the direction of flow is therefore too

tempering and mixing fluids in accordance with the flow direction of the Temperierungsfluides. However, it is also possible to operate the mixer heat exchanger 200 in countercurrent operation, in which case the flow direction of the fluid to be cooled and mixed is opposite to the flow direction of the temperature control fluid and either the temperature control fluid inlet 110 becomes the tempe- rature fluid outlet, or the fluid inlet 210 to Fluid outlet is. The same applies to the fluid outlets 220 and the tempe- rature fluid outlet 120, respectively. Figure 9 shows an alternative embodiment of a mixer-heat exchanger insert arrangement, but in which the temperature control fluid inlet and the tem- perature fluid outlet 110, 120 are not arranged on opposite sides, but on one side , in Figure 9 left. In this case, the tempering fluid flows in via the tempering fluid inlet 110, flows through at least one channel through the individual mixer-heat exchanger inserts to the opposite end and is there deflected via a corresponding coupling piece 130 between the separate flow volumes such that the tempering fluid passes through from the outflow channel flows back again to separate return flow channels to the Temperierungsfluidauslass 120. It should be understood that the arrangement shown in Figure 9, for example, may have two separate volumes, which are connected to the coupling piece 130 with each other. Alternatively, the embodiment shown in FIG. 9 can also have four separate internal volumes, which are connected to each other at the end by a corresponding coupling piece 130 such that two channels serve as the outflow channel and two channels as the return flow channel.

FIG. 10 shows an end view of the arrangement 100 shown in FIG

Temperierungsfluideinlass 1 10 and a Temperierungsfluidauslass 120th

Figure 1 1 shows a sectional view of an arrangement shown in Figure 9 in the region of

Temperierungsfluideinlasses or -auslasses 1 10, 120. From Figure 1 1 it can be seen that the flowing over the Temperierungsfluideinlass 1 10 tempering fluid in the

corresponding hollow body plates 10 and 20 flows in order to then flow back over the insert not shown in detail or the arrangement in order then from the

Hollow body plates 1 1, 21 to Temperierungsfluidauslass 120 to arrive.

FIG. 12 shows a partial sectional view of the arrangement shown in FIG. 8, in which a three-dimensional representation of the four-channel arrangement 100 is depicted, which is located in the fluid-carrying volume 230 of the mixer-heat exchanger insert arrangement 200.

FIG. 13 shows an exemplary schematic view of the inclination directions R1 and R2 with respect to the web-shaped hollow body plates 10, 11 of the first group and the web-shaped hollow body plates 20, 21 of the second group. As can be seen from FIG. 13, the inclination direction R1 of the hollow body plates of the first group 10, 11 is identical, just as the inclination direction R2 of the hollow body plates of the second group 20, 21 is identical. The inclination direction is opposite and the corresponding inclination angle α (alpha) with respect to the longitudinal axis L for both

Inclination directions R1 and R2 are the same.

FIG. 14 shows an alternative embodiment in which hollow body plates of a first group, hollow body plates of a second group and hollow body plates of a third group are provided. In this case, the hollow body plates of the first group 10 relative to the hollow body plates 20 of the second group, as opposed to the hollow body plates of the third group 30 offset by 120 ° and inclined, so that through the three hollow body plates 10, 20, 30 shown here, a propeller-like arrangement results, which causes a good mixing of the liquid to be mixed and tempered. It should be understood that a plurality of the hollow body plates 10, 20 and 30 can be arranged one behind the other, which however can not be removed in FIG.

FIG. 15 shows a schematic view of the passageway in a mixer-heat exchanger insert 1 a. In this case, the tempering fluid flows through, for example, a Temperierungsfluideinlass 1 10a and thereby distributes to the two channel strands, which are designated by the letters a and b. Alternately, a hollow body plate of the first group with the inner volume 13a and a hollow body plate of the second group with the inner volume 23a are flowed through in the upper channel a. Analogously, a hollow body plate of the first group with the inner volume 13b and a hollow body plate of the second group with the inner volume 23b are alternately flowed through in the second lower channel arrangement.
