Abstract

The heating radiator has a heating medium flow guide section (18,20) as a tube section fitted into an existing radiator and/or structured to be activated in an existing radiator. The tube section (18,20) is a knee piece with a fitting or coupling to be attached to the feed and/or return flow.

Description

The invention relates to a radiator for centralized heating systems, in particular for a riding or a hanging connection to this, according to the preamble of Claim 1.

In the prior art, there are radiators with a heating area, a front and a Return connection and a guide section to a heating medium from the flow connection to transfer to the heating area or from the heating area to the To return line connection known, which requires the guide section therefore to be provided so that the heating medium introduced into the radiator does not block the way of the least resistance takes and directly from the flow connection via a Short circuit flows into the return connection without appreciably closing the radiator heat.

In the case of larger radiators with a mounted connection method problems of this kind are particularly serious, since the inclination of the heating medium, the path of the least resistance, is particularly pronounced here. If, for example a radiator has a height of several meters and forward and return on the lower end of the radiator are provided on the manifolds, has the heating medium overcome a much lower resistance if it avoids the heating tubes and flows directly through the lower manifold from the flow to the return without one to achieve significant heating output.

The same applies to a hanging connection made in countries in which the central heating system is in the roof of a building. When riding Connection to the heating center, such as a central heating boiler, is provided in the basement.

With the hanging connection, a guide section is accordingly on the Return side of the radiator is provided so that the radiator the cooled Heating medium can be extracted from its coldest point.

Here it has proven disadvantageous in the prior art that when planning Buildings must be determined how the radiator should be connected so that A suitable guide section in the finished radiator is already factory-set could be provided. It was not uncommon for planning errors to occur, which led to this have that radiators were incorrectly dimensioned and manufactured incorrectly. Such Radiators not used for the construction project for which they were ordered could be, had to be converted with great effort.

In addition, there is the disadvantage in the production that, for example, in one Sectional radiator an end section specially for the purpose of riding or hanging Connection had to be designed by feeding a specific end link and attached, especially had to be welded. This leads to an increased Workload, with corresponding links of a sectional radiator separately in smaller quantities have to be produced, which involves an increased outlay is.

Furthermore, it results in the known radiators that an entire link one Sectional radiator or a tubular radiator for the conduction of the heating medium from the flow connection provided at the lower end of a radiator to the The upper end of the radiator must be done from where the heating medium over Collector pipe to be distributed over all elements or heating tubes of the radiator can. This leads to a reduction in the heating capacity, since the heating medium is initially in the first link must first climb before it is evenly distributed in the radiator can. Reductions in heating output of up to 8% have been determined here.

It is therefore the object of the present invention, the disadvantages listed above remedy as far as possible in the prior art. In particular, it is the Object of the present invention to provide a radiator that is variable the requirements of a riding connection or a hanging connection can be adjusted.

The above object is achieved by a radiator with those listed in claim 1 Features resolved. Advantageous embodiments of the invention are characterized by the Subclaims defined.

The advantages to be achieved according to the invention are based on the fact that the guide section is designed so that it can be used in the finished radiator and / or that this is designed to be activatable or activatable in the finished radiator is provided.

This makes it possible for radiators or the elements of radiators to be uniform train, after which, depending on the purpose and size of the concerned Radiator, a guide section can be activated or mounted to a corresponding Optimally manufacture and use radiators.

In this case, the guide section can be added subsequently via the forward and / or return usable pipe section, the the flow or for the hanging connection the Return connects to the heating area of the radiator so that the heating medium only can get through the radiator via a predetermined, inexpensive route, the Heating medium is advantageously distributed to a favorable overall performance of the radiator to provide. It is not necessary for the guide section to be in the form of a tube or any line, completely tight the flow connection of the radiator to a part that already practically belongs to the heating area of the radiator Line continuation follows, since it should only be achieved that the heating medium, preferably water, the majority of which is passed through the radiator in a controlled manner, small amounts of leakage are not important.

Compared to the proposed solutions according to the present invention, it was in the state the technology common, baffle plates, blind plates, lances and the like for guiding the Heating medium to be provided during the manufacture of the radiator. This limited the use of the radiator and made sure that a particular radiator only was suitable for a specific installation situation in a building, which was also the case with Manufacturing leads to logistical problems when namely in mass production certain radiators must be assigned to a specific order.

Such problems no longer occur according to the invention, because in the event that a corresponding radiator with critical dimensions or for a critical one Installation situation comes into consideration, only a corresponding guide section according to the Invention can be assigned to any radiator and then the guide section can only be used on the construction site or preparatory to the craftsman.

For certain installation situations, a line section can also be used as a guide section are suitable, which is designed as an elbow. This is particularly the case if the Flow connection to the radiator horizontally, i.e. especially at the bottom of the Radiator, and then the heating medium first inside the radiator or its heating area must be transported to over from there all parts of the heating area to be distributed. The line or Pipe section have a diameter that is smaller than the associated pipes or lines of the heating area or the radiator, so that the corresponding trained guide section can be relatively easily inserted into the radiator, wherein then a fixation can be carried out, for example by flange sections, the dimensions of at least approximately to the assigned line sections of the Heating area or the radiator fit, so that if possible only small Leakage quantities of heating medium occur, which are of the intended flow path for the Heating medium can deviate.

Advantageously, the guide section or its part in the radiator becomes so formed that the pipe or pipe section opposite a fitting or coupling section lies in which the line or pipe section can be fixed. This is one permanent assembly possible.

Of course, the guide section or the line or pipe section in the Completed radiators may already be included, but only by certain Measures is activated. For example, a perforated plate in the radiator in the Area of the flow or the return, which are provided by a sealing plug, a screw or the like is to be closed or removed corresponding parts can be released.

A particularly advantageous embodiment according to the invention results when a Line section or a tube is provided, which or in a corresponding Radiators can be introduced via the flow or the return, these Pipe or this pipe in the assembled state on the flow side or Return side has a flange section, which in the flow of the radiator can be used, for example via a thread, by gluing, soldering, Welding or the like. The pipe or pipe of the guide section can be used are rotatably and / or longitudinally displaceable in the flange section, so that the Flange section used as a flow and possibly as a return for the radiator can be held while the pipe section in the flange section is, but, as already indicated, it is movable in the flange section, so that the line or pipe are brought into the desired position in the radiator can. Appropriate activities can be carried out easily, so that the with Assembly associated effort and the associated costs are much lower are than according to the conventional way, with a corresponding, according to the Invention trained radiators can be used much more variably than conventional ones Radiators in advance for a specific purpose and for a specific connection method had to be trained in manufacturing in the factory.

Another very advantageous embodiment results when in the radiator in A leading section is introduced, which has a closing section, approximately in the form of a sheet or the like, which or in one Position in which a flow from one area of the heating area to another Area of the heating area can be influenced or prevented, is movable. It can the closure section because of its own spring force and thus by the Deformation of the closure section, in particular a sheet, in the radiator on the desired position, but a safety device can also be For example, a screw or the like can be provided, via which the closure section is fixable or adjustable in one position, the securing device can be operated from outside the radiator. The security device themselves can also be used to possibly determine a specific bypass flow through the radiator.

The closure section can advantageously be designed such that it more than one flow or line section from one area at a time another area of the radiator. This way it can be made possible be, for example in a sectional radiator or in a link of one Tubular radiator, the heating cables or heating tubes that are not for the management of the Heating medium to the upper or lower section of the radiator, depending on whether the Radiators must be prepared for riding or hanging connection, are required to be excluded, so that only one line section of a link for the flow, which is unfavorable with regard to the overall performance of the radiator must be used from bottom to top, while the other heating cables or Heating tubes of the relevant link for a good heating performance of the radiator more favorable flow direction from top to bottom can be used.

The closure section can have at least one, preferably also several legs have, which by the securing device, in particular a screw, in a Position can be moved in which flow or line sections in the heating area or added or opened in the assigned flow or return connection area can be placed in an associated position by the securing device is screwed further into or out of a thread a thread is screwed out to the legs of the guide section in a To move the closure position or an opening position.

1a, 1b and 1c is a radiator with features according to the invention shown in sections. The radiator has heating tubes 10 and manifolds 12. At the flow of the radiator 10, 12, a connection section 24 is preferably in the form of a Screw sleeve provided, which in a corresponding flow opening in the header 12 of the radiator is used waterproof. In this embodiment, this hereinafter referred to as screw sleeve 24, a thread 22 with a corresponding Counterpart in a flange part 20. In the flange part 20 is a Flange section 18 of a line or a pipe elbow 14 both rotatable and axially kept movable. At the other end of the tube 14 there is also a flange 16 provided that connects the tube 14 to the heating tubes 10.

Behind the tube 14 there is a connection opening 28 to another heating tube detect.

If the pipe 14 is inserted into the flow opening of the radiator, the flange section can 20 are connected to the screw sleeve 24, for example by screws, the flange 18 of the tube 14 being movable relative to the section 20. A Abutment 26 is preferably on a rear portion of the threaded flange 20 provided and holds the line 14 via the flange 18 at least at one end position in front of the abutment 26.

In the illustrated embodiment, the line 14 can do almost everything Transfer the heating medium directly from the flow into the first heating tube, so that for the transfer of the heating medium is only a single heating tube of a link Tubular radiator is needed. The same applies to a sectional radiator, as shown in Fig. 2a.

According to FIGS. 2a and 2b, a correspondingly designed guide section can be in the form a pipe 14 with flanges 16, 18 now in a sectional heater be introduced to prevent the heating medium from being essentially unused can flow out of the radiator. Parts shown in Figs. 2a and 2b are there otherwise essentially with the relevant parts of the embodiment according to 1a to 1c agree, except for the fact that it is in the embodiment 1a to 1c is a tubular heater, while it is the embodiment according to FIGS. 2a and 2b around a conventional sectional radiator acts, identified by the same reference numerals. Consequently, in FIGS. 2a and 2b a detailed description is omitted.

In Fig. 3, a tubular heater is shown again, which essentially Tubular heater according to FIGS. 1a to 1c is formed, but instead of one Collector tube has three header tubes 12 at the lower section of the radiator. Accordingly, such a radiator has a total of six manifolds 12.

Otherwise, the embodiment according to FIG. 3 corresponds to the guide section the embodiment according to FIGS. 1a to 1c. 3, however, is too note that only one heating tube 10 is used as the riser, although the first 3 has a total of four heating tubes 10. To this Way can also be avoided here that the heating power of the radiator by unfavorable flow for the heating medium in the first link of the radiator is deteriorating.

The embodiment according to FIGS. 4a and 4b is shown in a radiator, such as it has already been mentioned with reference to FIG. 3. However, here is the Guide section fundamentally different. Here is in the middle manifold 12th at the lower end of the radiator in the area of the flow, a blind disk 36 provided, which holds a cylindrical mounting portion 38, in which a threaded part 34th is recorded. If there is a danger given the design of the radiator, that this due to a riding connection or hanging connection and its size is not advantageously flowed through by the heating medium can Flow connection or the return connection a screw 34 from the outside in the Radiators are screwed to the middle manifold 12, from the flow seen to close behind the first heating element with heating tubes. The middle one The manifold is designed differently from the outer manifolds 12. While the outer manifolds have respective openings 28, the middle manifold is without these openings 28 are formed so that the heating medium can only rise upwards. Different collecting pipes for the heating register of this radiator must be used be used.

If the same header pipes 12 are used with respective openings 28, that is The heating medium is then forced to move into adjacent areas of the radiator branch. However, this type of connection is not preferred as the Connection according to FIGS. 1, 2, 4, 5 and 6, since here also heating medium in the neighboring heating tubes, which then serve as risers for the radiator serve what leads to a reduction in the overall heating capacity of a corresponding Radiator can lead, so that a corresponding radiator is larger from the outset must be dimensioned in order to be able to provide the same heating power.

As can be seen, is between the head of the screw 30 and the threaded cylinder 34 a sealing rubber 32 is arranged. This can, but does not have to be used as it is it does not matter that the connection is sealed watertight.

Instead of the presented, technically more sophisticated solutions, of course, could also Plastic closures are used, which are provided with a resilient area, which opens into a constriction area to which a flange section adjoins. Comparable closures are for multiple closures for mineral water bottles etc. known. Such a closure could also be used, one or a plurality of the openings 28 at times according to one of the illustrated embodiments or to close permanently.

The embodiment according to FIGS. 5a, 5b is for use in a rectangular one Collector tube 12 is provided, on the sides and upward heating tubes 10th can also be connected via the openings 28. In the illustrated Embodiment, a sheet 52 is used in the rectangular cross section, the one Has opening that a screw, in the present case an Allen screw 50, sealed, which is held by a nut 54, which is soldered to the sheet 52, can be welded or glued.

The sheet 52 can be designed in a wide variety of ways. It can go all over Width or extends over the entire cross section of the rectangular tube 12, since this only after the arrangement 50, 52, 54 has been introduced by means of the connecting flange 24, for example, a screw sleeve or the like, is narrowed or closed. The sheet can be designed so that it also the openings 28 (see Fig. 5b) closes, i.e. the sheet in this case has side wings that in the Accordingly, the sectional view according to FIG. 5a cannot be seen while they are in 5b as a thick solid line across the Openings 28 can be seen. If the screw 50 is removed, water can pass through again the rectangular manifold 12 flow, which is considered when the radiator is not connected mounted or hanging and / or the radiator has no dimensions has that bring the short-circuit problem mentioned at the outset with it could.

In the illustrated embodiment, only the heating tube 10 shown is as Riser pipe required so that adjacent heating tubes reached through the openings 28 could not be used as risers, but in the cheaper Flow direction from top to bottom (in the riding connection method) can be flowed through, so that the total heating capacity of a corresponding Radiator is not significantly affected.

6 shows a further, very advantageous embodiment of a radiator with Features according to the invention. Here, too, are the manifolds with the reference symbol 12 and the heating tubes with the reference number 10. The manifolds are connected to each other via cross connections 13, which via openings 28 open into the collecting pipes.

The flow connection or the return connection is a particularly advantageous here Guiding device with regard to the riding and / or hanging connection customizable. In the middle manifold 12 is a mounting or abutment plate 64b provided that has an opening for a screw 60 and accordingly can be provided with a screw thread. In this respect a sheet metal screw is used plate 64b need not be threaded. On plate 64b a U-shaped spring closure element is provided. The legs 64d of the spring lock element have a position 62a in which the openings 28 are adjacent Manifolds 12 are not closed. If the closure element 62a, 62b already is contained in the non-activated state in the radiator, this is for the inflowing Water is not a hindrance since the base 64a of the closure element has a hole, through which the heating medium or water also in the longitudinal direction of the central collector pipe 12 can flow. Only when the screw 60 into the opening in the part 64b is introduced into the radiator, the middle manifold 12 in Locked in the longitudinal direction, so that the heating medium only through the cross connections 13 and by a heating tube 10 (not shown) which is perpendicular to the middle Collector tube 12 stands, can flow. If the screw 60, driven by a Allen section 64, further sunk into the radiator, directs the head of the Screw 60 the spring legs 64d of the closure element against the openings 28, see above that the spring legs 64d can close the openings 28. Now that can Heating medium only via the middle (not shown) heating tube 10 in the Radiators rise upwards, where the heating medium then flows over the upper ones Manifolds 12 can distribute down over the heating tubes 10 in the radiator flows and passed through the illustrated manifolds 12 in the direction of the return becomes. So that the closure element can be pre-assembled, but closes in the Position 62a without the screw 60 is not one of the intended flow paths while it is in position 62b with the screw 60 inserted, only one way namely opens the way vertically upwards over the heating tube 10 (not shown) in this way the heating power of the radiator and especially the last link of the Optimize the radiator.
