Connection system for radiators

The invention relates to a connection system for radiators, in particular for single or multi-layer panel radiators through which a heat transfer medium flows.

Connection fittings are known that consist of a first housing part, which is usually arranged in an upper corner area of the radiator behind the radiator or between the radiator plates, and a second housing part, which is arranged on the same side in the lower corner area. The two housing parts are also connected in the state of the art by a riser pipe. Depending on the intended use of the radiator in question, namely whether it is to be installed in a

Two-pipe system, one-pipe system or conventional connection technology and depending on whether the lines carrying the heat transfer medium in the lower connection area are fed in from below or from the side, a wide variety of housing shapes with differently designed flow guide elements are required. This means a lot of manufacturing effort for the manufacturer. This is also disadvantageous for the user because the user has to order the corresponding products according to the later purpose when ordering. Accordingly, warehousing and procurement of spare parts is also expensive.

Based on this state of the art, the invention is based on the object of creating a connection system for radiators which, using a few standard parts, enables adaptation to different systems (one-pipe system, two-pipe system or conventional connection).

The solution to this problem is specified in claim 1. The basic element of the connection system consists of the

first housing part, the second housing part and the means that connects them in terms of flow, in particular a riser pipe. One or more connection modules can be combined with this basic element, so that the basic element can be easily adapted to the respective application.

Preferred further training courses are specified in the sub-claims.

Embodiments of the invention are illustrated in the drawing and described in more detail below.

A riser pipe 5 is connected to the first housing part 1 coaxially to the connection opening 4 of the first connection means 2, via which the first housing part 1 is connected to a second housing part 6. The second housing part 6 has two first connection means 7, 8, one of which has a horizontally directed connection opening in the installation position, which is parallel to the axis of the connection opening 4 of the first connection means 2 of the first housing part 1, and the other of which has a vertically downwardly directed connection opening 10 in the installation position. The second housing part 6 can be connected in terms of flow to a plate of a single-layer radiator or to both plates of a two-layer radiator via further second connection means 11. In addition, connection modules 12 to 16 are provided, which alternatively

or can be connected cumulatively to one of the two first connection means 7, 8 or to both first connection means 7, 8 of the second housing part 6 or can be integrated into them, wherein one of the first connection means 7 or 8 or both first connection means 7, 8 can be connected to the lines carrying the heat transfer medium.

The first housing part 1 has a connection piece as the first connection means 2, which is directed horizontally in the assembly position and runs to the outside or outer edge of the corresponding radiator, with the riser pipe 5 connected to the housing part 1 being directed with its mouth end coaxially to this connection piece. The shapes of the housing parts 1 and 6 are spherical, with the respective connection pieces (connection means 2, 7, 8) being welded to the spherical housing or connected to it in another suitable manner. In addition, the housing part 1 or 6 has a hole in which the riser pipe end of the riser pipe 5 is sealed.

The first housing part 1 has as second

The connecting means 3 has one or two transversely projecting connecting pieces, which can be tightly connected to the plate or plates of the radiator. In the drawing according to Figure 1, the corresponding connecting piece projects backwards through the plane of the drawing.

Likewise, the second housing part 6 has connection pieces 7, 8 as first connection means and transversely projecting connection pieces 11 as second connection means, which can be tightly connected to the plate or plates of the radiator.

The riser pipe end of the riser pipe 5 opens into the second housing part 6 coaxially to the horizontally directed connection opening 9 of the first connection means 7 or to the correspondingly directed connection piece in the housing part 6. In the embodiment, the riser pipe end of the riser pipe 5 protrudes into the first housing part 1 or into the second housing part 6. When the base part according to Figure 1 is used in a two-pipe system with a lateral connection to the lines carrying the heat transfer medium, a first connection module

which is designed as a through sleeve with an axial flow passage. This first connection module is inserted into the horizontally directed connection opening 9 of the first connection means 7 of the second housing part 6 and is tightly fitted onto the end of the riser pipe. This creates a sealed connection between a line carrying the heat transfer medium connected to the connection opening 9 or the corresponding connection piece and the riser pipe 5. The first module component 12 is also arranged in a sealed manner with its end located in the connection piece (first connection means 7). The downwardly extending opening 10 of the other first connection means 8 is in an open line connection with the second housing part 6 and the second connection means 11. A corresponding arrangement is shown in both Figure 2 and Figure 3. The further differences between these embodiments will be explained later.

According to Figures 4 and 5, a second connection module 13 is alternatively designed as a through-sleeve with an additional radial fluid outlet 17, whereby

this second connection module 13 is in turn inserted into the horizontally directed connection opening 9 or the corresponding connection piece of the second housing part 6 and is plugged onto the end of the riser pipe 5. This forms an essentially sealed connection between a line carrying the heat transfer medium connected to the connection opening 9 or the connection piece and the riser pipe 5. The radial flow medium outlet 17 forms an additional flow connection to the second connection means and to the downwardly directed connection opening 10 or to the downwardly directed connection piece, to which a further line carrying the heat transfer medium can be connected.

Such a design is suitable and intended for single-pipe operation. In this respect, too, the differences between Figures 4 and 5 will be explained later.

In the embodiment according to Figure 6, a third connection module 14 is provided, which is designed as a sleeve that does not have an axial flow passage

-10-

but is closed by a wall part 18. This connection module 14 has only one or more radial flow passages 19. This third connection module 14 is either inserted into the horizontally directed connection opening 9 or the corresponding connection piece of the second housing part 6 and preferably tightly plugged onto the end of the riser pipe 5 or inserted into the horizontally directed connection opening 4 or the corresponding connection piece of the first housing part 1 and preferably tightly plugged onto the end of the riser pipe 5. As a result, the riser pipe opening is closed by the wall part 18 of the third connection module 14. The other end of the third connection module 14 can be connected to the line carrying the heat transfer medium via the connection opening 9 or 4, so that a flow connection is formed between the connected line via the third connection module 14 and the second connection means 11 or 3 to the radiator, wherein the downwardly extending connection piece of the housing part 6 or the connection means 8 is closed, in particular by means of a sealing plug 16.

In order to create an adaptation to different installation conditions, a fourth connection module 15 is designed as an angled passage piece, with its outlets directed at right angles to one another. One end can be connected tightly to one of the two first connection means 7 or 8 or one of the two connection nozzles of the second housing part β, with the other end forming a connection for a line carrying the heat transfer medium, with the connection being axially parallel to the mouth of the first connection means 7 or 8 or corresponding connection nozzle that is not equipped with the fourth connection module. The design according to the invention makes it possible to adapt the standard component according to Figure 1 to a wide variety of installation situations. In the installation situation according to Figure 2, the radiator can be operated in a two-pipe system with a side connection. The flow connection can be connected to the horizontally directed first connection means 7 in accordance with the arrow 20. The connection module 12 forms a closed line connection between this first connection means 7 and the riser pipe 5, whereby the

Connection module 12 is arranged on the riser pipe end and in the bore of the housing part 6 with sealing means in between. The connection module 15 is tightly inserted into the first connection means 8 and represents an outlet for the return line indicated at 21, which is directed axially parallel to the flow line 20.

Using the same connection module parts 12, 15, it is also possible to operate the radiator in a two-pipe system with downward-facing connections, which are illustrated in Figure 3. The connection module 15, like the connection module 12, is inserted into the first connection means 7, so that, for example, the flow connection 20 can be introduced into the connection module 15 from below, while the return flow is sealed into the downward-facing first connection means 8. The variants according to Figures 4 and 5 illustrate the operation of a radiator with a side pipe connection or with a bottom pipe connection in a one-pipe heating system. The second connection module 13 is used here, which is inserted into the first connection means 7 and placed on the end

of the riser pipe 5. Through the lateral perforation (17) a portion of the flow can be fed directly back to the return 21, while the remaining portion of the flow 20 is led via the riser pipe to the upper housing part 1. By using the fourth connection module 15, which is plugged into either the first connection means 8 or the first connection means 7, a lateral line outlet or inlet according to Figure 4 or a downward-facing line outlet and inlet according to Figure 5 can be realized. In the embodiment according to Figure 6, the operation of a radiator with a conventional connection is possible. A complete valve, in particular a thermostat valve, can be inserted into the flow line 20, for example, in front of the first housing part, in particular in front of its first connection means 2, so that the flow line 20 can flow into the first housing part 1 depending on the valve position and from there into the plates of the radiator via the second connection means. The flow line cannot flow directly to the second housing part 6 via the riser pipe 5, since the passage is blocked by the wall part 18. Rather, the heat transfer medium can flow into

the housing part 6 via the second connection means, then flow into the connection module 14 via the radial openings 19 and from there flow out via the first connection means 7. By moving the closure plug 16 into the first connection means 7, the heat transfer medium can alternatively also flow out via the connection means 8.

With regard to the fourth connection module 15, it should be noted that this can be screwed into the corresponding connection piece in a telescopically adjustable manner, so that tolerance compensation between the available connection pieces for the connection lines carrying the heat transfer medium is possible.

Instead of a riser pipe, the means connecting the two housing parts 1,6 can also be formed by channels of the radiator itself, which is known per se in the prior art.

Figure 12 shows an embodiment in which a flow chamber 22 is separated from the plate of the radiator 27. The flow chamber

22 is separated from the cavity of the plate of the radiator 27, for example by a weld seam.

In this design, the two housing parts 1,6 are connected to the flow chamber 22 in an open manner (at 23 and 24). Coaxial to the first connection means 2 and 7 are connecting means 25, 26, in the design example pipe sections, diametrically opposite the first connection means 2 and 7, fixed to the housing parts 1,6. These connecting means 25, 26 openly lead into the second connection means 3 and 11, which in turn lead into the plate or plates of the radiator 27. In this case, the flow chamber 22 essentially replaces the otherwise usual riser pipe.

With this design, the arrangement of the connection modules is also possible and necessary depending on the intended use. In the conventional operation of a radiator 27 equipped in this way, in which a shut-off valve or thermostat valve is connected to the opening 4 and in which the pipe-side connection goes from the opening 9 or 10, the first connection module is integrated into the first connection means 2.

12, so that a direct and exclusive flow connection is formed from the mouth 4 of the first connection means 2 via the connecting means 25 and the second connection means 3 to the plate or plates of the radiator 27.

The invention provides a connection system for radiators that enables a wide range of applications using fewer standard components. This reduces the manufacturing effort, as well as the storage and transport costs.

The invention is not limited to the embodiment, but is variable in many ways within the scope of the disclosure.

All new individual and combination features disclosed in the description and/or drawing are considered essential to the invention.
