Abstract

The present invention relates to a tube radiator for the targeted and serial approach flow of at least two groups of essentially tubular heating elements.

Description

tubular radiator

The invention relates to a tube radiator with a plurality, preferably tubular

Heating elements, which are to flow through with suitable heating medium.

Tube radiators usually consist of several groups of heating elements designed as heating tubes, which are mechanically and fluidically connected at their end regions in each case via a connecting tube. The flow connection and the

Return connection are usually provided on the outer sides of the respective outer radiator elements. In this case, the flow connection and the return connection can be provided on the same side of the radiator at the top and bottom, on opposite sides respectively above or below or preferably in the lower, central position relative to the radiator.

In known tube radiators, the flow through the plurality of layers or groups of heating elements is usually carried out simultaneously and in the same direction, for example in vertically arranged heating tubes either in a flow direction from bottom to top or top to bottom, depending on the arrangement of flow and return connection.

In practice, however, it has been found that a radiator produces greater comfort and the heat losses to the wall on which the radiator is mounted, are lower, if for a given heating power, the directed into the room front of the radiator, a higher temperature has as the outer wall facing the rear side.

This principle is known, for example, from EP 0 890 800 B1, which discloses a single or multi-row radiator with at least two differently designed sections concerns, wherein directed into the space heating section is formed in the form of a heating plate. The flow connection is arranged on the heating plate directed into the room either at the top or bottom on one side. The supplied heating medium first flows through the front heating plate and only then thereafter, the further heating sections provided behind it or the several further heating sections provided behind it. The front

Heating plate and the one or more heating sections provided behind it are connected only by a connecting line on the side opposite the feed port of the radiator.

In this way it is achieved that initially directed into the room heating plate from

Heating medium is flowed through, so that this heating plate has a higher temperature and a higher radiation component than the other or the other heating sections.

The invention is based on this prior art, the object to provide a radiator with at least two layers of heating elements, in particular a Röhrenradiator, which on one side (preferably the directed into the room front) emits a higher radiant power than the other side and which achieves this goal by a simple, space-saving and inexpensive construction.

The invention is based on the recognition that the principle described in EP 0 890 800 Bl for generating a higher radiant power in radiators, which have a heating plate and a further heating section arranged behind it at least on its front side, can also be transmitted to tube radiators. These tubular radiators comprise at least two groups of heating elements, wherein the groups are preferably arranged in a layer-like manner one behind the other and each group comprises at least two juxtaposed heating elements. The radiator according to the invention comprises at least two groups of heating elements, wherein a first group faces the space to be heated, while the at least one further group is facing away from this space and arranged behind the first group. According to the task, the group of heating elements facing the room should preferably be heated. This is done according to the invention in that the two groups are connected to each other via two common connection pipes, in which all the heating elements of the group incorporate together.

From a preferably upper first connecting pipe, therefore, heating elements of the group facing the space extend on the one hand and open into a preferably lower common connecting pipe. Furthermore, the heating elements of the second, remote from the space group are connected to the upper and lower common connecting pipe.

To the heating medium provided by the flow first the heating elements of the

Room-facing group zuzuleiten, according to the invention a release agent in the first upper connection pipe is provided, through which this connection pipe is divided into two chambers. The division is preferably carried out in the longitudinal direction of the connection pipe, so that two adjacent chambers occur over the entire length of the connection pipe. Thus, although the two groups are connected to a common upper or first connection pipe, the release means arranged in the connection pipe permits the separation of the connection regions of the first and second group within the connection pipe.

In particular, the feed medium introduced into one of the chambers can be guided from there exclusively into the heating elements of the first group facing the room. The heating elements of the second group are connected to the other chamber of the upper and first connecting pipe, so that the coming of the flow hot medium can only get directly into the heating elements of the first, but not the second group. In this way, it is particularly simple and very effective to ensure that the different groups of a tube radiator can be selectively or selectively supplied with heating medium, since the second group, which is also connected to the upper connection tube, is separated from the chamber connected to the flow line. Such a tight separation within the connecting tube avoids any flow into a group not intended for this purpose (this would be disadvantageously possible, for example, if instead of the chamber distribution only a tube provided with directed nozzles was arranged in the connecting tube, the outflow of the flow in the direction of However, as long as the heating elements of another group can be reached directly from the common connection pipe, corresponding flow or heat losses are unavoidable.)

An embodiment of the tube radiator according to the invention therefore comprises at least two groups of preferably at least two, in particular tubular heating elements arranged one behind the other. The heating elements can be flowed through by a heating medium, wherein the heating medium can be supplied to a flow connection of the tube radiator and can be led away from a return connection of the tube radiator. Each group is arranged with its heating elements between a pair of connecting pipes to connect the connecting pipes fluidly with each other. The heating medium flows essentially from one of the two connecting pipes coming into the heating elements of the group in order to then flow through them and from there into the associated second connecting pipe.

According to the radiator is thereby provided that at least one connecting pipe is provided, in which a separating elements is provided to divide the connecting pipe into a first and an adjacent second chamber, and thereby an overflow of heating medium from one chamber into the other chamber of the sliding - Prevent connecting pipe. Outwardly, the connection pipe remains as a common with pipe for all connected thereto heating elements or groups, while in this common pipe, the separation is made.

According to the invention, in this case heating medium can be introduced into a specific chamber and, from there, selectively continued only into that group which faces the room or should be heated more strongly than subsequent groups. By suitable flow guidance, the heating medium downstream of the first group can also enter the second chamber of the split connection pipe and be guided from there into at least one further group whose heating elements are in direct communication with this second chamber. This design advantageously allows a simple specification of the flow paths of the heating medium (first the group facing the room, then one or more other groups).

Thus, it is conceivable, for example, to feed heating medium into a first chamber of a connection pipe which is divided by separating means, after which the medium from this

Chamber flows into the heating elements of a first group, which are facing the room to be heated. The heating medium leaves the heating elements of this first group in a common second connecting pipe. The heating elements of a second group facing away from the space can be connected to this second connecting pipe-without a separating separating element-so that the medium flows into these heating elements. Preferably, these heating elements lead back to the upper first connecting pipe, where the heating medium opens into the second, separate from the first chamber chamber to be fed to the return there. This particularly simple embodiment thus requires only one connecting pipe with a separating element inserted therein in order to ensure a clear serial flow through the groups of heating elements.

In continuation of the inventive concept, it is provided that the second, preferably lower connecting pipe of the pair, which is connected by the groups, divided by a separating element into two chambers, substantially analogous to the dividing development of the first connection pipe of this pair. Such a pair will be referred to hereinafter as the "separating chamber pair." A pair of connecting tubes exhibiting separation chamber pair is thus characterized in that each connecting pipe is divided by a separating element into a first and an adjacent second chamber to prevent overflow of heating medium from a chamber to prevent the other chamber of the same connecting pipe.

This design advantageously allows a simple and particularly advantageous flow guidance of the heating medium (first the group facing the room, then one or more other groups). Also, the desired is targeted

Flow in a particular group by the inventive division of the connection pipes in two chambers space and material saving and visually appealing allows, the groups are connected to a common pair of connecting pipes.

Typically, this development of the invention provides that heating medium again enters the first chamber of the first connecting pipe and from there into the group which faces the space. However, the heating medium emerging from this group is now guided in a targeted manner into a first chamber of the second connecting pipe, wherein there is no direct fluidic connection from this chamber into the adjacent chamber of the second connecting pipe. Instead, the heating medium from the first chamber of the second connecting pipe according to the invention is introduced directly into at least one heating element of a second group, wherein the other heating elements of this group are directly connected to the adjacent second chamber of the second connecting pipe.

In particular, the forwarding of the heating medium from the first chamber of the lower or second connecting pipe can take place through an opening in the separating element, to which the said heating element of the second group is directly connected. As will be apparent from the figure representations, arrived ie, the heating medium coming from the first group from the common first chamber of the second or lower connection pipe directly into a heating element of the second or next or adjacent group, without any medium being able to flow directly into the adjacent chamber.

Instead, the medium is led up through the at least one heating element into the second chamber of the first connection pipe. The other heating elements of the second group open directly into this second chamber, so that the inflowing from the at least one heating element heating medium can flow into the remaining heating elements of this group. By the heating elements of this group, the heating medium then passes down into the second chamber of the lower and second connecting pipe, from where it can be supplied to the return.

The advantage of such a flow guide is firstly that the flow can be integrated in the area of the first or upper connection pipe, while the return flow is taken off at the second or lower connection pipe. Furthermore, the heating medium is guided in almost all heating elements from top to bottom. As a result, unwanted flow effects due to density or temperature differences are largely prevented.

As already described, it is provided for such an embodiment that in the - preferably second or lower - connecting pipe of the separating chamber pair, an overflow device allows the passage of heating medium from a chamber into at least one heating element of a group whose further heating elements are directly adjacent to that in the connecting pipe Chamber are connected.

For the aforementioned example, it results here that the chambers of the separating chamber pair are fluidly connected in series so that first a first chamber of the first connecting pipe and then a first chamber of the second connecting pipe associated with the separating chamber pair are flowed through, after which again the second chamber of the first connecting pipe and finally the second chamber of the second connecting pipe is flowed through. All chambers are thus flowed through successively and alternately between the connecting tubes of a separation chamber pair. With such a flow restriction, there is the advantage that the heating elements of the groups connected in series are flowed through in substantially the same direction, that is, for example, from top to bottom. Only the at least one heating element, which is acted upon directly from the adjacent chamber, stirs the heating medium against the other heating elements of its group.

A particularly simple embodiment of the invention provides that only two

Groups of heating elements are connected to a separation chamber pair, wherein the groups and the chambers are flowed through successively, as described above. In this case, the first chamber of the first connecting pipe would be directly connected to the first chamber of the associated second connecting pipe by the heating elements of a group, while the second chamber of the first

Connecting pipe with the second chamber of the associated second connecting pipe is directly connected by the heating elements of the other group. The two groups are flowed through here in succession.

An advantageous embodiment of the invention further provides that from a first chamber of a separation chamber pair is not fed directly into the heating elements of a group, but first in an adjacent connection pipe. It may be a simple manifold to which one or more groups of heating elements are connected in parallel, wherein in this connection pipe no separating element is provided and all connected heating elements are acted upon simultaneously with heating medium. Typically, these parallel-flow groups connect the abovementioned connecting tube to a second common connecting tube, from where the heating medium is then introduced into the first chamber of the second connecting tube of the adjacent separating chamber pair. The further guidance of the heating medium is carried out as described above, wherein from the first chamber of the second connecting pipe, a targeted overflow is again formed in a heating element of a further group of heating elements, wherein the other heating elements of this further group are directly connected to the adjacent chamber.

The separation chamber pair would in this case preferably face the wall. The other, the above-described simple connection pipe associated groups, however, would be directed into the room to be heated, since these pipe elements are first flowed through and together in the described embodiment. In this application, therefore, the tube radiator would consist of three groups of heating elements. The first group would be arranged between the separation chamber pair, the second group would be connected parallel to the third group to a simple pair of connection pipes, these connection pipes would be directly connected to the first and second chamber of the separation chamber pair.

Conceivable here is also an embodiment with only two groups, in which case the additional pair of unseparated connection pipes can be omitted for the sake of simplicity. Conversely, of course, more than two groups of heating elements can be flowed through in parallel.

In continuation of the inventive concept, however, the use of a plurality of separation chamber pairs is conceivable, which can be arranged adjacent to each other directly or indirectly. For example, from the first chamber of a first separation chamber pair, the heating medium could be introduced via suitable supply lines into a first chamber of a second separation chamber pair. There, the medium flows through the heating elements connected to the first chambers of the second separation chamber pair, enters the first chamber of the second or lower connection pipe associated with this second separation chamber pair; from there, the heating medium passes by means of suitable Überströmöffhung in a heating elements of another group, whose other heating elements directly with the adjacent second chamber of lower connection pipe of the second separation chamber pair are connected; in this heating element, the heating medium rises again up to the second chamber of the first connecting pipe of the second separating chamber pair; passes from there into the other heating elements of the group and is led back down to the second chamber of the lower connection pipe of the second separation chamber pair; from there it will turn

Heating medium through suitable connection tubes fed back to the first separation chamber pair, in the first chamber of the second or lower connection pipe of the first separation chamber pair; from here again, the heating medium is introduced by a suitable Übertrittsöfmung in a heating element of another group whose remaining heating elements are in direct communication with the adjacent second chamber of the lower connecting pipe of the first separation chamber pair; Finally, the heating medium passes through the other heating elements of this last group in the second chamber of the lower connecting pipe of the first separation chamber pair, from where it can be fed to the return.

Such an arrangement of a plurality of mutually adjacent separation chamber pairs allows the exact specification of the flow paths through a plurality of groups of heating elements in succession. In the above-described case, the heating medium could therefore be supplied to the first room facing the room to be heated first, which is adjacent to the first group and disposed towards the wall. A third

Thereafter, a group of heating elements can be flowed through, this group for example, facing directly to the wall. As a result, the task proper management of heating medium by individual sectors or groups of heating elements of a radiator can be accurately predetermined, and the heating medium cools it on its way from the room to the wall.

In principle, according to the invention, it is also possible to combine a plurality of separating chamber pairs with "simple" connecting pipe pairs in any desired constellation. According to a further advantageous Ausfuhrungsforrn the invention, a chamber of a separation chamber pair is connected directly or via a valve disposed on the radiator valve to the flow. Preferably, the valve is arranged upstream of the first, so first of all flowed through chamber of the separation chamber pair. If the valve is installed directly on or in the radiator, the flow of this valve is to be supplied according to the invention by a specifically selected heating element of a group.

For example, supply and return connections can be available in the lower or bottom area of the radiator. In this case, the supply is suitably passed through the lower connection pipe of the separation chamber pair, without being connected to this pipe or its chambers. Instead, the flow is integrated directly into a heating element, which leads the heating medium upwards into the first connection pipe of the separation chamber pair. There, the heating element is connected directly to the flow connection of the valve, without being fluidly connected to one of the chambers. The heating medium flows through the valve and then passes into the first chamber of the upper connecting pipe of the separating chamber pair, from where it is continued in the above-described ways.

The heating element arranged upstream of the valve can also be designed as a double-walled

Be provided tube so that heating medium occurring downstream of the valve can be passed through the annular gap or the inner tube of this heating element.

Of course, it is alternatively or additionally also possible to design the return of the tube radiator according to the invention such that at least one heating element of a group is connected directly to the return connection of the heating element with a first end, so that the return can take place exclusively via this heating element. Depending on the arrangement of flow and return connections at the installation of the radiator, this return flow or flow guidance by at least one heating element of a group may be useful. Preferably, the groups of heating elements are arranged substantially vertically, as this allows a space-saving orientation of the radiator in the room to be heated. Furthermore, the individual groups or their heating elements are preferably arranged in each case in one plane, so that a plurality of groups would have to be understood in the manner of layers stacked one behind the other. The groups are preferably arranged one behind the other in such a way that the respectively associated heating elements are aligned with one another. A horizontal cross-section through a tube radiator according to the invention would result in the image of a matrix, wherein the rows or columns can also have varying distances from each other.

Further advantageous embodiments will become apparent from the dependent claims.

Below some embodiments are to be explained in more detail with reference to figure representations. Show

1 shows several representations or views of a first embodiment of a tube radiator 1 according to the invention. Two groups A, B of heating elements 2 are connected together to an upper connecting tube O ₁ and a lower connecting tube U ₁ . The two connecting pipes O ₁ and U ₁ form a separating chamber pair. (Some heating elements 2 as well as other components are not marked with the corresponding reference number in each figure).

While the heating elements 2 of the group B are arranged substantially in a straight line between the connecting pipes O ₁ and U ₁ , those elements of the group A arcuately run between the two connecting pipes, so that the tubular radiator 1 has a substantially D-profile in the side view.

In Fig. 1 a) can also be seen that the upper connecting pipe O ₁ and the lower connecting pipe U _{1 are} each divided by a schematically indicated separating element T into two adjacent chambers OK ₁ , OK ₂ and UK ₁ , UK ₂ .

In Fig. 1 b), the rear group B is shown in connection with the upper and lower connecting pipe O ₁ , U ₂ , while Fig. 1 c) represents the front group A. With the aid of dark and light arrows, the flow of the heating medium is indicated, with dark arrows indicating a higher heating medium temperature, while the brighter arrows are intended to indicate already cooled medium. Combined with Fig. 1 e), f) and g), which show an exploded perspective view of the radiator, the flow within the radiator will be explained in more detail.

In Fig. 1 e), the rear part of the radiator 1 is shown, wherein the heating elements 2 of the group B can be seen. The heating elements 2 and 2 'of the group B extend between the upper and the lower connection pipe O ₁ or U ₂ according to FIG. 1 a) or FIG. 1 d). In particular, the heating elements 2, 2 'of group B open at their upper end into an upper chamber OK _{2 of} the upper connecting pipe O ₁ . With their opposite end, all the heating elements 2 of the group B, with the exception of the heating element 2 ', open directly into the lower chamber UK ₂ .

As already explained with reference to FIG. 1 a), chambers are respectively realized by inserting a separating element T into the upper or lower connecting pipe O ₁ or U ₁ . In Fig. 1 f), this separating element T is shown schematically for the two connecting pipes. The separating element inserted approximately diagonally into the connecting tube of rectangular cross section forms in each case an approximately triangular chamber in cross section. The chambers OK ₁ and OK ₂ belong to the upper connecting pipe O ₁ and are formed substantially over the entire length of the connecting pipe. The same applies to the lower connecting pipe U ₁ , where another separating element T in a different orientation also defines a first and second chamber UK ₁ and UK ₂ , which are not directly in communication with each other in terms of flow. In Fig. 1 g), three elements 2 of the front group A are shown offset, so that their connection with the outside of the upper and lower connecting pipe is visible.

A tube radiator composed according to FIGS. 1 e), f) and g) functions according to the invention as follows:

Heating medium enters the chamber OKi of the upper connection pipe O ₁ via a flow connection (VL), not shown. There, the medium is distributed over the entire length of the chamber and flows through all the heating elements 2 of the group A down. Get there the heating medium in the formed in the lower connection pipe U ₁ first chamber UK. ₁ About a non-illustrated passage, the heating medium from the chamber UK _{1 is} selectively introduced into a heating element 2 'of the group B. Thus, the medium does not pass directly into the adjacent chamber UK ₂ , but only into the heating element 2 'of the group B, to be guided up into the second chamber

OK _{2 of} the upper connection pipe O ₁ . Within this chamber OK ₂ , the medium is supplied to all other heating elements 2 of group B, while a direct transfer into the adjacent chamber OK _{1 is} not possible. After passing through the heating elements of group B, the medium finally enters the lower chamber UK _{2 of} the lower connecting pipe Ui, where it is collected and fed to a return RL.

It can be seen from the arrows that first the heating elements of the group A are flowed through, and downstream of them the heating elements of the group B are arranged. Thus, the medium coming from the forerunner becomes the room-side first

Group A heating elements supplied and then passed through the elements of the group B in the return afterwards.

FIG. 2 shows an expanded form of a radiator 1 according to the invention. This radiator 1 comprises the heating elements of three groups A, B and C. All the heating elements are connected between an upper connecting pipe O ₁ and a lower connecting pipe U ₁ , the connecting pipes becoming one Separating chamber pair are formed, as already described for Fig. 1. The essential difference from the embodiment according to FIG. 1 is that the heating elements of groups B and C are essentially connected in parallel, that is to say they flow through at the same time. Excluded is again a heating element 2 'of the group B, which is analogous to the above-described embodiment model for supplying the heating medium into the upper chamber OK ₂ . Correspondingly, FIGS. 2 b) and 2 e) show circular connection openings for the heating elements of group C. In this embodiment, the heating medium flows analogously to the example of FIG. 1, first in the first chamber OK _{1 of} the upper connection pipe and from there through the heating elements 2 of the front group A. From the first chamber UK _{1 of} the lower connection pipe, the heating medium does not come through a The transfer opening shown in more detail directly into the heating element 2 'of group B, likewise analogous to the embodiment already described. In contrast to this variant, however, the heating medium flows from the second chamber OK _{2 of} the upper connection pipe not only in the other heating elements 2 of the group B, but also in all heating elements of the group C. Both groups open again in the second chamber UK ₂ of lower connection pipe, from where the heating medium can be fed to a return. In this variant, therefore, the group A is acted upon by heating medium in front of the parallel flowed through groups B and C.

Fig. 3 shows a modification of the radiator according to the invention in different variants.

According to FIG. 3 a), a first upper connecting pipe O _{1 is} connected via the heating elements of a group C to a first lower connecting pipe U ₁ . The connecting pipes O ₁ and U ₁ are designed as separating chamber pairs, that is to say they each have two separate chambers. Adjacent to this separation chamber pair, another pair of connection pipes O ₂ and U ₂ (without separating elements) are arranged, this pair being connected by the heating elements of a group A and a group B.

According to the invention in this embodiment, as shown in FIG. 3 a), the heating medium again in a non-designated first chamber OK _{1 of} the first upper connection pipe

O ₁ initiated. From there it passes via suitable supply lines directly into the adjacent upper connection pipe O ₂ . This connecting pipe O ₂ as well as the associated lower connecting pipe U ₂ does not have a separating element, instead the two groups A and B are simultaneously supplied with or flowed through by heating medium. From the lower connecting pipe U ₂ , the heating medium passes back into the unspecified first chamber of the first lower connecting pipe U _first From here, the medium is again supplied to a heating element of the group C in the manner already described, as a result of which it can flow upwards into the second group of the first upper connection pipe. From here, in turn, the remaining heating elements of the group C flows downwards, so that the heating medium can finally be removed from the second chamber of the lower first connecting pipe U ₁ .

According to this embodiment, therefore, the two groups facing the space A and B are simultaneously flowed through, while then the wall facing the group C is subjected to heating medium.

A combination of the embodiments according to FIG. 2 and FIG. 3 a) is shown in FIG. 3 b). In addition to and parallel to the heating elements of the group C heating elements of a further group D are arranged. In contrast to the embodiment according to FIG. 3 a), therefore, the heating medium flows through the group C and in parallel with it

Group D at the same time, wherein the group D is connected via separate upper and lower connection pipes O ₃ and U ₃ with the separation chamber pair O ₁ and U ₁ .

The connecting pipes O ₃ and U ₃ according to FIG. 3 b) can also be omitted if the pipes of the group D are connected to the separating chamber pair as shown in FIG. 3 c). Here, too, the groups A and B are again flowed through, then the heating medium rises in a defined heating element of group C upwards, from there into the second chamber of the first upper connection pipe and is split there in parallel to all other heating elements of group C or D.

A continuation of this idea leads to an embodiment according to FIG. 3 d). There are a total of five groups A, B, C, D and E arranged. Here, too, the heating medium introduced into the upper first connecting pipe O ₁ first passes back into the upper connecting pipe O ₂ , which is formed without separating chambers and thus acts on the groups A and B simultaneously or in parallel. From the lower connection Röhr U _{2 then} passes the heating medium via a short connecting line to the lower first connecting pipe U ₁ , which is divided according to the invention into two chambers. Again, by a heating element of the group C, the heating medium is led upwards into the second chamber of the first upper connection pipe O _first There, the stream is split into the further heating elements of group C and into an adjacent upper connecting pipe O ₃ . This in turn is connected to the heating elements of two groups D and E without separating element, so that these groups D and E are flowed through in parallel to the group C. The groups D and E are summarized in the lower connecting pipe U ₃ , which also has no separating element, from where the heating medium enters the second chamber of the first lower connecting pipe U ₁ . In the same chamber further heating medium also passes through the heating elements of the group C, so that the divided into three sub-streams flow is summarized and can be removed.

It is readily apparent that these embodiments can be expanded as desired, and further packets can be provided by groups connected in parallel with one another.

The use of more than one pair of separators is also conceivable in order to be able to determine the flow of the heating medium through the individual groups in precise sequence.

Fig. 4 shows a more detailed representation of the embodiment of FIG. 3 a), which has been omitted for reasons of clarity on a complete use of reference numerals. It can be seen in Fig. 4 b) again the separation chamber pair O ₁ , U ₁ and the heating element 2 'of the group C, is guided by which heating medium from the first lower chamber back up into the second upper chamber. FIG. 4 c) shows, in a further side view, the two groups A and B one behind the other, which are connected together to the upper or lower connecting pipe O ₂ or U ₂ .

According to the above-described embodiments of the invention, it has always been provided that the heating medium is guided into the first chamber of the first lower connection pipe U ₁ in order to be conducted out of this chamber by means of a suitable overflow device into a heating element 2 'of a further group of heating pipes. According to the representation of FIG. 4 e), however, the formation of two separate chambers in the first lower connecting pipe U _{1 is} not absolutely necessary. Since the heating medium from the groups B and A is already collected collectively in the second lower connecting pipe, the direct connection of this heating element from the second lower connecting pipe U ₂ through the first lower connecting pipe U ₁ suffices for targeted return of the heating medium into the heating element 2 ' , This connection can be realized, in particular, by a connecting element extending from the edge of the first lower connecting pipe U ₁ directly to the heating element 2 '(pipe section, angled pipe, hose, etc.), as indicated by dash-dotted lines in FIG. 4 e) for the element 3 is.

For this embodiment, therefore, a separating element for forming two chambers in the first lower connecting pipe U _{1 is} not absolutely necessary.

FIG. 5 shows a tube radiator according to the invention with a laterally inserted valve. In contrast to the previously described embodiments, in this case according to FIG. 5 b) it is provided to guide the flow through a heating element 2 "of the group B facing the wall. The heating element 2 "is passed through the lower connecting pipe U ₁ (separated from the latter in terms of flow) and supplied with the feed from below. The valve V arranged in the upper connecting pipe O ₁ is directly connected to the heating element 2 via a suitable connecting line 3" Downstream of the valve V, the heating medium then passes again in the first chamber of the upper connecting pipe O ₁ , so that the further flow guidance can take place in the manner already described.

The further illustrations of this FIG. 5 correspond analogously to those of the previously described examples.

Fig. 6 shows an embodiment of the radiator according to Fig. 5, in which again two groups B and C are connected in parallel. Again, the valve V is connected via a heating element 2 "and a suitable connecting line 3" to the flow. Analogous to the embodiment of FIG. 2 is to the upper second separation chamber

OK ₂ additionally the group C connected, through which the heating medium is led parallel to the group B.

Analogous to the embodiments according to FIG. 3, further designs of the tube radiator according to the invention are shown in FIG. 7, in which case the flow is not introduced into the radiator on the front side, but preferably from below through the aforementioned heating element 2 " 3 essentially correspond to those of FIG. 7, in which case the return also takes place vertically downwards and not via an end-side connection (the latter was illustrated in FIG. 3).

Fig. 8 shows a combination of the embodiments of FIG. 5 and 4. A heating element 2 'of the group C serves to return heating medium in the first upper connecting pipe O ₁ , while a second heating element 2 "of this group C of

Supply of heating medium from the flow directly to the valve V is used.

The embodiment of FIG. 9 takes into account the case that the connections for supply and return are arranged approximately centrally below the radiator 1. In this case, to provide the flow to the valve V, a heating element 2 " chosen, which is located near the center of the radiator to attach this accordingly. Furthermore, this embodiment coincides with that of FIG. 5.

10 shows, analogously to the illustration according to FIG. 2 or FIG. 9, a tube radiator with three groups A, B, C, which in turn is designed for connection to a supply arranged essentially centrally underneath the heating element. The further design features of this embodiment correspond essentially to the previously described variant having only two groups according to FIG. 2 in conjunction with FIG. 5.

In Fig. 11, the features of the variants of Fig. 5 and 9 are combined. Shown is there a tube radiator with three groups A, B and C, of which the two groups A and B are flowed through in parallel, before then group C is flowed through. The feed connection (as well as the return connection) is arranged substantially centrally below the heating element, so that heating medium is supplied from the supply line to its valve V via a substantially centrally arranged heating element 2. The further flow guidance corresponds to that described for FIG.

In Fig. 12 is an example of an embodiment of a fiction, contemporary separator T can be seen. In conjunction with FIG. 1, the shape and arrangement of the separating element T within an upper or lower connecting pipe can be seen. The idea would be to replace the separating element T in the upper first connecting pipe O ₁ according to FIG. 1 by the separating element according to FIG. 12 a), while the separating element T according to FIG. 12 b) would be to be arranged in the lower first connecting pipe U ₁ according to FIG ,

The separating element T according to FIG. 12 a) is designed in the form of an angled sheet-metal strip which has a rounded profiling at its ends. When used in the upper first connecting pipe O ₁ , the separating element T terminates with the upper or lower inner wall of this connecting pipe, so that the pipe is inserted into the two chambers OK ₁ and OK _{2 is} split, which are side by side. The frontal view X or the sectional view AA additionally clarifies the design of the separating element T. The bulges or rounded profiles at the ends of the separating element T are intended to facilitate the arrangement or installation of heating body components (in particular valves or inlets or outlets). facilitate. A the

Inlet limiting valve according to the type of Fig. 5 would be sitting in a bulge, which is connected to the first upper separation chamber OK ₁ .

The separating element T according to FIG. 12 b) serves for use in a lower connecting tube U ₁ in an analogous manner. The chambers formed by this partition T

UK ₁ and UK ₂ are exemplified based on the sectional view BB.

In connection with FIG. 1 i), the use of the separating elements T becomes particularly clear when the separating elements shown schematically in FIG. 1 f) are shown schematically replaced by diagonals of FIG. 12.
