Description

The The invention relates to a tube radiator having the features of the preamble of claim 1.

column radiators usually consist of several layers of than heating tubes trained heating elements, which at their end over a Collection chamber mechanically and fluidically connected are. This form in such tube radiators the usually one after the other in the individual layers arranged heating tubes with the associated sub-collection chambers Radiator elements, which have a hub-like design Connecting areas, each with an adjacent radiator element are connected. In this way you can tube radiators produce different width in a simple manner. The flow connection and the return port are usually on the outsides of the respective outer radiator elements intended. In this case, the flow connection and the return connection provided on the same side of the radiator top and bottom his or on the opposite sides each top or below.

The hub-like connecting portions of the individual radiator elements usually have a breakthrough, so that the individual radiator elements or the heating medium leading Partial collecting chambers and the heating tubes fluidically are connected.

Of the The term "fluidically connecting" is thereby in the following as a delimitation to a purely mechanical connection understood, whereby merely expressed should that the heating medium by a fluidic connection with the adjacent heating medium in connection, but not necessarily a flow through the relevant fluidic Connection must be made.

At usual Tube radiators are flowing through the several layers of heating tubes usually each in the same direction, for example in vertically arranged heating tubes either in a flow direction from bottom to top or top down, depending on the arrangement of flow and return connection.

In In practice, however, it has turned out that a radiator Greater comfort and heat loss to the outer wall, on which the radiator is mounted is lower, if at a given heat output the in The front of the radiator facing the room is higher Temperature than the outer wall facing the rear side.

This principle is for example from the EP 0 890 800 B1 known, which relates to a single- or multi-row radiator with at least two differently designed sections, wherein the directed into the room heating section is designed 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 flows through first the front heating plate and only then 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 are connected only by a connecting line on the side of the radiator opposite the flow connection.

On This way is achieved first in the room directed heating plate is flowed through by the heating medium, so that this hot plate has a higher temperature and a higher radiation component than the other or the other heating sections.

Of the Invention is based on this prior art, the task to create a tube radiator, which on its front gives a higher radiant power as on its back and which one simple and inexpensive Construction has.

The Invention solves this problem with the features of the claim 1.

The invention is based on the recognition that in the EP 0 890 800 B1 described principle of generating a higher radiant power in radiators having at least on its front a heating plate and a further heating section arranged behind it, is also applicable to tubular radiators having at least two layers of heating elements, each layer of heating elements also at least two juxtaposed heating elements includes.

The invention is based on the recognition that known constructions of tube radiators can be modified in a simple manner in order to achieve the goal of flowing through the front heating elements and the relevant parts of the head regions in front of the rear heating elements and the relevant parts of the head regions. For this purpose, according to the invention in the volumes of the head portions of the radiator elements Strömungsleitmittel provided for the heating medium, which are designed so that the volumes of the radiator elements are fluidly divided into a front half and a rear half, wherein the front and the rear half each have a partial volume of the relevant Head areas and the volumes of one or more include heating elements. A radiator element will usually have a plurality of tubular heating elements arranged one behind the other, wherein the volumes of the heating elements are fluidically connected at each end to the volume of a head region. The entire tube radiator consists of adjacent radiator elements, which are each hub-like connected to the head areas.

The Flow guide elements are designed so that over the flow connection first of all front halves the radiator elements, a heating medium can be supplied, wherein the supplied heating medium in the front halves each of the volume of one of the head areas in the volume of each other head area flows and then over a or several overflow openings of the front in the back half of one or several or all radiator elements overflowed, the overflowing heating medium in the rear Halves each from the volume of one of the head areas in the volume the other header area flows. After flowing through the rear halves becomes the heating medium the return connection removed.

To An embodiment of the invention can in each radiator element Flow guiding means with an overflow opening between the front and back half be provided. However, in this embodiment, depending on load case, d. H. depending on the flow rate of the over the supply connection supplied heating medium, an uneven Temperature distribution across the width of the tube radiator result.

According to the invention Therefore, according to a preferred embodiment, only a single Flow guiding means with an overflow opening provided in each load case, first a flow through the front halves of the radiator elements and only then a flow through the rear halves to ensure the radiator elements.

To An embodiment of the invention may instead of flow guides with an overflow opening in the volume of the head region concerned, the flow guide also completely eliminated. The provision of defined overflow openings However, this can be exploited to get to the point in question to generate a defined flow resistance.

To According to an embodiment of the invention, the flow guiding means be designed so that the front and back Halves each adjacent radiator elements each either at both head areas (fluidic parallel connection the two adjacent halves) or at only one head area (Fluidic series connection of the two adjacent Halves) are fluidly connected. As a result, the flow path within the entire front or backward Half, d. H. the flow through the adjacent front or rear halves of the Radiator elements are forced in the desired manner. Are adjacent halves each at both head areas fluidically connected, so there is a fluidic Parallel connection of the respective adjacent halves (in particular the Heating elements). Become adjacent halves alternately each at the one and at the other head area fluidly connected, so results a serial flow through adjacent halves, wherein in the adjacent heating elements, a respective opposite Flow direction results.

On This way, a virtually arbitrary flow pattern can be reach through the individual halves of the radiator elements. Reversing the flow direction in one half can be used particularly advantageous if the flow or return connection at a certain head area (eg up or down) is desired.

To According to one embodiment, the flow guiding means For example, be designed so that the front and back Halves of all radiator elements on each both head areas (fluidic parallel connection of all Halves) or in only one head area (fluidic Series connection of all halves through the alternating connection each of a header area) with the respective head areas adjacent radiator elements are fluidly connected.

The Flow guiding means can in one embodiment the invention be designed so that the front half of the flow connection having radiator element only on that Head area fluidly with the relevant front half of is connected to adjacent header, where not the flow connection is provided to the via the flow connection of the front Half of the relevant header Heating medium completely the other head area supply. In this way, the flow direction can be reverse at least in the second heating element. This allows the flow connection as specified, either at the top or bottom of the head be arranged, wherein at the same time in the other heating elements a desired flow direction can be realized is.

In the same way, the flow-guiding means may be formed such that the rear half of the radiator element having the return connection is only fluidic at that head region is connected to the respective rear half of the adjacent head portion to which the return port is not provided to supply the entire, this rear end portion of the head medium supplied to the head portion to which the return port is provided. As a result, the return connection can be arranged according to the appropriate specification either at the upper or lower head region, wherein at the same time a desired flow direction can be maintained in the further heating elements.

To an embodiment of the invention, the Flow guide in the longitudinal direction the radiator aligned partition walls, which include the Volumes of the head portions of the radiator elements and, if present, also the volumes of connection areas between the head areas each two adjacent radiator elements, in the two halves, these partitions the required overflow between the front and back half have or these partitions in the case of a required overflow completely or completely missing.

The Flow guide for fluidic connection or separation the respectively adjacent front and back Halves of adjacent radiator elements can by the walls of the head areas in the areas of the hub-like Connection of the radiator elements may be formed, these walls for fluidic connection flow openings exhibit. The dividing walls must be up to each to the inner wall of the relevant wall of the head portions in protrude the connection areas to a fluidic separation of the front and rear halves too guarantee. The flow openings must then each in an area of the respective Kopfbereichswandung lying, which of the front and / or the rear Half is to be added.

Becomes no fluidic connection of the front and / or rear Halves of two adjacent radiator elements desired, so can the walls of the head areas in the areas the hub-like connection of the radiator elements to the fluidic Separation of the respective halves of adjacent radiator elements either have no flow openings or the flow guide for fluidic separation of front and rear halves adjacent Radiator elements comprise closure means which are in the walls the head areas in the areas of the hub-like compound of Radiator elements formed throughflow close. In the latter case, the radiator elements, regardless of whether a fluidic connection certain or all head regions is desired or not identical be educated.

To a preferred embodiment of the invention can the radiator elements of shell-like housing elements exist, which are tightly connected at its outer periphery and between them the volumes for the heating medium in the Define head areas and the areas forming the heating elements, wherein the volumes of head regions of adjacent radiator elements via apertures fluidly connected in the areas of the hub-like connection are. The flow guide can then as separate inserts are formed in the head areas are inserted between the housing elements. You can either by positive or non-positive connection in one finished radiator be fixed.

The two inserts for a radiator element can each having a partition wall, the two halves Define the volumes of the radiator elements by the respective Head area in the two volumes of the front and rear Separate halves.

The Half shells can in turn consist of two halves each exist, wherein a separation takes place in a plane in which the dividing walls are. This can be at least half of the half-shells in one process, for example a deep-drawing process be made together with the dividing walls. The respectively another half of a half shell can be either identical be formed so that the dividing walls of each two adjacent (or slightly spaced) Compose (part) partitions, or substantially identical, However, be formed without partitions. The halves the half-shells can then, for example by soldering or welding, firmly connected to half-shells that then be connected in turn to each a radiator element. Of course, first of all, too two adjacent halves of two half-shells of a Radiator connected to a half radiator element and then two such half (in a longitudinal plane of the Radiators separate) radiator elements to a whole radiator element be assembled.

According to one embodiment of the invention, the inserts may be formed so that each of the two adjacent inserts of two adjacent radiator elements cooperate such that the volume of a transition region between the adjacent radiator elements is a separation into a front and a rear half he goes, the Insert parts, apart from overflow openings in the respective adjacent Ra Diatorelement and / or in the other half, preferably identical.

One Insertion part can be designed according to an embodiment of the invention be that the partition wall between each two outward, preferably cup-shaped holding portions of an insert is formed, wherein the partition wall substantially tight the inner wall of the respective head area is applied.

The Provision of dividing walls is generally preferred in an area of the head area between two junctions of heating elements, as here by simply designed, for example level partition walls, a seal can be reached.

To An embodiment of the invention, the holding areas engage the inserts in wells of the housing elements, which for forming a hub-like connection of the radiator elements are provided and in which breakthroughs are provided wherein the cup-shaped holding regions are formed, that they are the front and the rear halves of neighboring Radiator elements either substantially against each other or seal connect fluidly, preferably by means in the holding areas provided flow openings.

Further Embodiments of the invention will become apparent from the dependent claims.

The The invention will be described with reference to the drawing Embodiments explained in more detail. In the drawing show:

1 a schematic, broken-away perspective view of a first embodiment of a four-column radiator according to the invention with flow and return port on the same head portion of a radiator element;

2 a perspective, partially exploded view of a second embodiment of a four-column radiator according to the invention with separate Strömungsleit elements with flow and return port on the same head portion of a radiator element; and

3 a representation similar 2 a further embodiment with flow and return port on opposite head portions of a radiator element.

The in 1 illustrated four-column tubular radiator 1 has five radiator elements 3 on, the hub-like coupling areas 5 connected to each other. Each radiator element 3 has a total of four tubular heating elements 7 on, at their ends in one piece with each a head area 9 are connected. The in the heating elements 7 and head areas 9 defined volumes are also fluidly connected and are traversed in the manner explained in more detail below by a heating medium which the Röhrenradiator 1 via a flow connection 11 fed in and from the tube radiator 1 via a return connection 13 is dissipated. Both the flow connection 11 as well as the return connection 13 are in the illustrated embodiment at the top of the head 9 a first, outer radiator element 3 arranged and fluidly with the in the radiator elements 3 connected volumes.

In the head regions are in a median plane which is symmetrical to the longitudinal direction of the heating elements 7 runs, flow guide in the form of partitions 15 intended. The dividing walls 15 are substantially planar and lie with its outer periphery on the inner wall of the respective head portion 9 on, so that there volume of each radiator element in a front half 17 and a back half 19 is shared. As will become clear later, it is not absolutely necessary to have a perfectly tight separation of the front halves 17 and rear halves 19 to ensure, however, is a sufficient or even completely dense separation of the two halves 17 . 19 desirable.

The head areas 5 the radiator elements 3 show in the area of the coupling areas 5 each aligned openings on the front and rear halves 17 . 19 adjacent radiator elements 3 in the connected state via flow openings 21 connect.

As in 1 shown, the radiator elements 3 be formed identically, wherein the flow openings 21 may be configured so that at the desired positions of the outer radiator elements 3 the flow connection 11 and return port 13 can be mounted in the openings, which at the mutually facing coupling areas 5 adjacent radiator elements 3 the flow openings 21 define. Not for the supply connection 11 or return connection 13 required openings on the outer sides of the outer radiator elements 3 can by means of closure elements 23 be sealed tightly. One or more of the closure elements 23 can of course also be designed so that the relevant closure element as a venting device for the Röhrenradiator 1 can act.

Hereinafter, the flow of the heating medium is explained in more detail, which the Röhrenradiator 1 via the flow connection 11 is fed in the arrow direction. The heating medium passes over the Flow connection 11 in the front half of the relevant volume of the first radiator element 3 and enters both the front portion of the respective head portion as well as in the two front heating elements 7 as well as in the front section of the respective lower head area 9 , It should be noted at this point that the Röhrenradiator 1 preferably mounted on a wall such that the front of the radiator, which is the two front rows of heating elements 7 and the respective front portions of the head portions 9 the radiator elements 3 includes, is directed into the room. As a result, the proportion of radiation from the tube radiator 1 is dispensed compared to conventional Röhrenradiatoren increased. Because the front half of the tube radiator 1 is first flowed through by the heating medium, whereby the heating medium cools and only then in the rear half of Röhrenradiators 1 arrives. This is achieved at the same time that the heat losses through the wall, at which the Röhrenradiator 1 is mounted, compared to known tube radiators is reduced because the rear half of the tube radiator 1 a lower temperature than the front half.

The tube radiator 1 supplied heating medium passes through the flow openings 21 in the upper, front halves of the radiator elements 3 also in all other radiator elements 3 , wherein these are traversed in the same way by the heating medium, as the radiator element 3 at which the pre-ignition startup 11 is arranged.

In the lower head areas 9 are also partitions 15 trained and the coupling areas 5 also have flow openings 21 on (not shown). Only in the last radiator element 3 (at the opposite of the flow connection 11 opposite side of the tube radiator 1 ) is in the lower header a partition wall 25 provided, which an overflow 27 having. As a result, the entire heating medium, which is the front halves of the radiator elements 3 via the flow connection 11 is supplied via the overflow 27 the rear halves of the radiator elements 3 supplied in each lower head area.

Since the rear halves of the lower head areas also via flow openings 21 in the hub-like coupling areas 5 are connected, the two rear heating elements 7 each radiator element 3 flows through from the heating medium from bottom to top. The heating medium then passes over the rear halves of the upper head areas 9 the radiator elements 3 towards the return port 13 guided, in which case also the rear halves of the head areas 9 via corresponding flow openings 21 are connected. These are however in the representation in 1 not recognizable, since this part is broken up or broken away.

This ensures the in 1 illustrated tube radiator 1 a serial flow through the front and rear halves, so that the desired effect of a room higher temperature can be ensured.

Of course, it would also be conceivable in each of the lower partitions 15 one overflow opening each 27 provided. As a result, each of the entire front and rear halves of the tube radiator volumes would be 1 However, not connected in series, so that in this case can result in different load conditions but distinctly different warm areas of Röhrenradiators.

Instead of a fluidic parallel connection of the adjacent radiator elements 3 each in the front and back half, it would also be possible to adjacent front or rear halves 17 . 19 to connect in series. For this only have appropriate flow openings 21 be closed, for example by means of corresponding closure elements (not shown). Of course, the radiator elements could 3 also already with corresponding coupling areas 5 are produced, which only at the desired locations breakthroughs to form the required flow openings 21 exhibit.

For example, it would be conceivable, the flow opening 21 in the front half between the first and second radiator element to close. This would be the two front heating elements 7 the first radiator element flows through the heating medium in a downward flow direction. By a in the lower front half between the first and the second radiator element 3 provided through-flow opening 21 then can the heating medium the two front heating elements 7 be supplied to the second radiator element. Are the front lower halves of the second and third radiator element 3 fluidly separated, so the heating medium can only in the two front heating elements 7 ascend the second radiator element. In this case, at least the front, upper halves of the second and third radiator element via a flow-through 21 be fluidly connected, so that the heating medium can get into further radiator elements. In this way, a meandering flow pattern in the front of the Röhrenradiators 1 be achieved. In the fifth and last radiator then the heating medium can again through the overflow 27 overflow into the back half. By providing or way let throughflow openings 21 between the front and rear halves 17 . 19 adjacent radiator elements can thus a virtually arbitrary flow pattern in the heating elements 7 be generated. It is also conceivable, for example, first the front halves 17 several adjacent heating elements in series and then to switch several adjacent, front halves in parallel. Usually, however, one becomes a parallel connection of the front and rear halves 17 . 19 the radiator elements 3 Provide, as this is a uniform heating across the width of Röhrenradiators 1 guaranteed.

By changing from a parallel to a series circuit of adjacent front and rear halves 17 . 19 However, for example, can be achieved that the flow or return port 11 . 13 at the other head area 9 the relevant radiator element 3 can be positioned. This is also clear from the embodiments explained below:

2 shows a tube radiator 1 which in turn consists of five radiator elements 3 that exists in the head areas 9 in the region of centrally arranged coupling regions 5 connected to each other. For mechanical connection are in the in 2 illustrated embodiment connecting elements 29 provided in corresponding breakthroughs 31 engage in the coupling areas. The breakthroughs 31 For this purpose, for example, each be provided with an internal thread, which with a corresponding external thread on the connecting element 29 interacts. This initially creates a fluidic connection of the entire volumes in the head regions 9 without having a fluidic separation into a front and back half 17 . 19 is present.

As in 2 illustrated, there is each radiator element 3 from two shell-like housing elements 33 , which are tightly connected to the outer circumference, for example by welding, soldering or the like. The half shells define both the head areas 9 as well as the four heating elements 7 a radiator element 3 ,

The desired fluidic separation of the tube radiator 1 in a front and rear half is achieved in this embodiment by flow guide elements, which are used as inserts 35 are formed. Each insert 35 includes two pot-shaped holding areas 37 that are in corresponding hollows 5a engage in the inner walls of the housing elements 33 in the area of the hub-like coupling areas 5 are formed. The front sides of the pot-shaped holding areas 37 or the circumferential, cylindrical walls of the holding areas 37 work with the hollows 5a together and ensure a sufficient tightness. Between the two cup-shaped holding areas 37 is a partition 39 provided, similar to the dividing wall 15 in the embodiment according to 1 with its outer periphery to the respective areas of the inner wall of the housing elements 33 defined radiator element 3 is applied. In this way, thus the separation can be done in each case a front and a rear half 17 . 19 a radiator element produced in this way 3 be achieved.

The breakthroughs 31 on the outsides of the outer radiator elements 3 be back on closure elements 23 closed, of which at least one in turn may have a venting function.

A fluidic connection of the front and rear halves 17 . 19 adjacent radiator elements 3 can in the case of in 2 illustrated inserts 35 be achieved in that in the respective bottom walls of the cup-shaped holding areas 37 flow openings 21 are provided. Inside the fasteners 29 is the fluidic separation of the front and rear halves 17 . 19 maintained by each one of the inserts 35 another partition 39a which engages in the hollow cylindrical volume, which in the connecting elements 29 is trained. The further partition wall 39a is formed so long that this through the relevant connecting element 29 through to the bottom of each facing cup-shaped holding area 37 of the insert 35 protrudes, which is held in the adjacent radiator element.

Instead of forming another partition 39a in each case only on one of the adjacent inserts 35 can of course also cooperating partition walls on both inserts 35 be provided.

Below is the flow of the heating medium in the in 2 illustrated tube radiator 1 explained in more detail. That via the flow connection 11 supplied heating medium is replaced by a suitable training of in 2 shown, combined flow and return port only the front half of the upper head area 9 of the first radiator element 3 fed. As a result, the heating medium in each case the two front heating elements 7 of the tube radiator 1 fed and enters the front half of the lower head area 9 of the first radiator element. By providing flow openings 21 in the bottom of each pot-shaped holding areas 37 of the insert 35 the heating medium is also the relevant front, upper half of the second and all further radiator elements 3 fed. The inserts 35 can this be identical forms out. Only the insert 35 in the last radiator element 3 may have a different shape, since there is no further partition 39a is required and this optionally in the trough or in the breakthrough 31 there is no room, as this is due to a closing element 23 is closed.

This results in the front half of the tube radiator 1 according to 2 the same flow as in the 1 illustrated embodiment.

In the lower head areas of the radiator elements 3 are also inserts 35 provided, which are formed substantially identical. These also have the parallel connection of the respectively adjacent front and rear halves 15 . 17 corresponding flow openings 21 on.

Only the insert 35 in the lower head area 9 of the last radiator element 3 points in the dividing wall 39 an overflow opening 27 on. Through this, the heating medium from the front half of Röhrenradiators 1 overflow into the back half. In the rear half, the same flow pattern results as in the embodiment in FIG 1 explained in more detail.

By providing or omitting flow openings 21 in the inserts 35 However, not only in 2 flow pattern shown, but virtually any desired flow pattern can be achieved, as described above in connection with the embodiment in 1 was explained in more detail.

In particular, in this way a tube radiator 1 as shown in 3 be realized in the flow and return connection to the opposite head portions of the first radiator element 3 are provided.

For simplicity, in the illustration according to 3 the flow connection indicated only by a corresponding arrow. The same applies to the return connection.

The heating medium is also used in the 3 illustrated embodiment via the flow connection (not shown) in each case the front halves of the radiator elements 3 supplied, which in turn via corresponding flow openings 21 are fluidically connected in parallel. In this front half of the tube radiator 1 thus results in the same flow as in the 2 illustrated embodiment.

After flowing through this front half of the heating medium flows through the overflow 27 in the insert 35 , which is in the lower head area 9 of the last radiator element 3 is provided in the back half about. In this back half of this radiator 1 In all radiator elements, except for the first radiator element, on which the flow and the return port are provided, the same flow pattern as in the embodiment according to FIG 2 , That is, also in the embodiment according to 3 are all rear halves 19 the radiator elements 3 , apart from the first radiator element, fluidically connected in parallel. This is done by appropriate flow openings 21 in the bottom walls of the holding areas 37 the inserts 35 guaranteed. Thus, the inserts have 35 in all radiator elements 3 , except for the first radiator element 3 , in each case in both bottom walls of the holding areas 37 two flow openings each 21 on. Only with the inserts 35 in the last radiator element can in the outwardly directed holding areas 37 to corresponding flow openings 21 be waived, since these were inoperative anyway.

The heating medium, which the rear halves 19 the radiator elements 3 , in particular the heating elements in question 7 Flowing upwards becomes the back half 19 the upper head portion of the first radiator element 3 fed, wherein a passage of the heating medium in the lower head area 9 locked because the insert part 35 in the lower head area 9 of the first radiator element 3 in the back half 19 no corresponding flow opening 21 having.

Since that in the upper head area 9 of the first radiator element 3 arranged insert 35 in the holding connection facing the holding area 37 in the back half 19 also no flow opening 21 has, mixing of flow and return is avoided. Instead, this becomes the first radiator element in the upper header 9 supplied heating medium from the upper head area 9 through the rear heating ele ments 7 down to the lower head area 9 promoted. Here shows the relevant insert 35 in the holding connection facing the return port 37 in the back half 19 a flow opening 21 on, via which the heating medium reaches the return port and can be removed from this.

Thus, based on the embodiment according to 3 clearly that by a corresponding serial or parallel connection of the rear halves of the radiator elements 3 Supply connection and return connection can be arranged at different head portions of the first radiator element.

It is also possible to supply and return port on opposite radiator elements 3 to position. For this purpose, for example, in the in 2 illustrated embodiment in the first radiator element 3 in the lower head area 9 provided insert 35 an overflow opening 27 while the overflow opening 27 omitted in the last radiator element. In this way, the passage of the heating medium takes place from the front to the rear half of the radiator 1 in the first radiator element, so that the return port can be positioned at the top of the head of the last radiator element. Of course, this must be in the bottom wall of the holding area 37 of the insert 35 in the upper head area 9 the last radiator element in the rear half of a flow-through 21 be provided. Instead of a combined flow and return port, of course, a simple flow connection can be used, which is the heating medium of the front half of the first radiator element 3 or in total the front half of the radiator 1 supplies.

By a combination of this above-described, modified embodiment with the principle of a reversal of the flow direction in an outer radiator element 3 according to 3 It is also possible to produce an embodiment of a tube radiator in which the flow connection is arranged, for example, on the first radiator element in the upper head region and the return connection on the last radiator element on the lower head region.

As From the above description, can by means of appropriate Insert a known tube radiator, at the all heating elements in the same flow direction are traversed by the heating medium, in an inventive Tube radiator to be transformed, in which a front Half of the tube radiator a higher Temperature than the relevant rearward Half.
