Abstract

The radiator has a panel (2) with connections (4,5,6,7) to feed and return pipes for the heating medium. Further pipe sections (8,9) branch off the connections for fastening to feed pipe and a return pipe. The free ends of the pipe sections are at a small distance relative to each other, and are directed in direction of the vertical central line (10) of the radiator panel. Connections and associated pipe sections are combined by a connection element (12) to form a connection module (13).

Description

The invention relates to a radiator with at least one of a heat transfer medium flowable heating plate and at least two connections connected to it Connection of the radiator with a flow line and a return line for the Heat transfer medium, with the connections on one side of the radiator in opposite Corner areas of the heating plate arranged and with their opening cross-sections in the direction are directed away from a vertical center line of the heating plate.

In such well-known radiators, the pipes of the supply and return lines usually horizontally into the opening cross-sections of the heating plate connections introduced. There is usually a 90 ° deflection of the flow in the connections the inside of the heating plate instead, with the entry of the heat transfer medium into the Heating plate takes place at an angle of approximately 90 ° to the heating plate level. The pipes of the The supply and return lines can either be at a certain horizontal distance from the Radiators enter a wall parallel to each other or both become minor horizontal distances from the heating plate which deviate from one another by 90 ° downwards deflected, for example, to enter a floor.

A disadvantage of the known radiators is that the possible variations for the routing of the flow and return lines are quite limited. In particular it is hardly possible to connect the supply and return lines behind the heating plate, i.e. in the area of Projection, to be misplaced, for example to hide it from a viewer's eyes.

The invention has for its object to propose a radiator in which one There are a variety of connection options for the flow and return lines, whereby in particular, concealed piping in the area behind the heating plate is also possible should be.

Starting from a radiator of the type described in the introduction, this object is achieved according to the invention solved in that each of the connections a further line section branches off for connection to a flow line and a return line, the ends the line sections are arranged at a short distance from each other and in the direction are aligned with the vertical center line of the heating plate.

The radiator according to the invention has the advantage that - without this changes made on the radiator or several types of radiators would have to be produced - Have different line routing for the supply and return lines. This is, for example, the classic horizontal installation directed away from the center line of the heating plate the supply and return line possible, which is strikingly with the Keyword "side connection" (visible) can be characterized. Of course the lines that start out horizontally from the connections after a short time Distance from the heating plate steerable in any other angular position. Furthermore is also an exact vertical alignment of the opening cross-sections of the connections to the vertical Center line possible. As an alternative to this, however, the advance and Return line from the ends of the other line sections in the direction of the vertical Center line of the radiator possible. In this regard, there is particularly a hidden one Laying the supply and return lines within a horizontal projection of the Heating plate in order to achieve a concealed arrangement for the viewer.

Despite the additional expenditure on material and components, the radiator according to the invention is ultimately cheaper than two alternative and parallel variants, because the advantages of a larger number of pieces and the avoidance of changeover times in manufacturing plants available. Logistics and space requirements are also simplified at Storage. After all, there is an enormous advantage for the user, who can also use the Purchase of a radiator of the type according to the invention between different connection types or choose how to route the supply and return lines. It it goes without saying that depending on the type of connection the user chooses, the two unnecessary opening cross sections of either the connections on the heating plate directly or at the free ends of the line sections with suitable means, for example Plugs, lids or valves that must be tightly closed.

According to an embodiment of the invention it is proposed that the distance between the center lines of the line sections in the area of their ends smaller than twice the line diameter is. While the connections are therefore arranged in the corners of the heating plate the greatest possible vertical offset between the inflow flow and the outflow flow to get, i.e. in order to heat the To achieve a hot plate, there is the possibility with the help of the line sections, their opening cross-sections as close as possible to each other, for example to save space and to make bundled laying of supply line and return line possible.

The ends of the line sections are preferably in a lower edge region of the heating plate arranged and / or perpendicular to a preferably vertical center line of the heating plate aligned.

In this regard, it can be advantageous if a line section runs in an S-shape, since in this case with a substantially identical alignment of both end sections, a large line offset can be achieved for example in the vertical direction.

For manufacturing and cost reasons, it is preferable if a connection and an associated line section form a coherent component, for example is produced by welding.

A further rationalization of production can be achieved if two connections and two assigned line sections via one near the ends of the line sections arranged connecting element are connected to each other to form a connection module. The Arrangement of the connecting element in the region of the ends of the line sections offers This is because there is a small distance between the two line sections and the connecting element can therefore be made very compact and stable. The connection module is preferably welded to the heating plate in the area of the connections. The connection element can also be welded to the heating plate be useful, which results in a stable three-point attachment.

To further increase the connection options of the radiator, the heating plate can be turned on two opposite sides, each with two connections arranged close to the corner, i.e. With a total of four connections.

It is also proposed according to the invention that the ends of the line sections aligned parallel to each other and offset by a small amount of length and / or are provided with an external thread, on the one hand for establishing a connection with the flow and return line and on the other hand to close the opening cross-sections in the case of using the connections arranged close to the corner.

According to a further embodiment of the radiator according to the invention it is provided that the ends of the line sections telescopically overlapping the ends of two others Line sections are coupled, which are connected together and together in the direction the center line of the line sections in the region of whose ends are displaceable.

In this way, tolerances when connecting the radiator in the simplest way be compensated without moving away from the desired arrangement of the radiator or Need to make changes to the existing installation.

In this regard, it is particularly advantageous if a connecting link between the line sections in their end position with a stop member connected to the heating plate is in contact. In this way it can be prevented that the telescopic connection unintentionally by pulling the movable line sections too far will be annulled.

Finally, it is provided that the displaceable line sections each by 90 ° are angled, which results in a horizontal arrangement of the telescopic connection the possibility of connecting the radiator in the central area to vertical pre and Return lines results.

A radiator 1 has a hot plate 2 through which hot water can flow All four corners of a view side 3 are each provided with a connection 4, 5, 6 and 7. The connections 4 to 7 are connected to the heating plate 2 by welding and each have an opening cross-section directed outwards and provided with an internal thread provided for connection to a flow or return line is. Furthermore, the heating plate 2 has a passage opening in the area of the connections 4 to 7 to allow the warm water to flow in or out.

Different from the connections 6 and 7, the connections 4 and 5 are each with one S-shaped line section 8 and 9 provided. The line sections 8 and 9 extend - in relation to the opening cross sections facing outwards - in opposite directions Direction, i.e. towards a center line 10 of the heating plate 2, and are each welded to a central part 11 of the connections 4 and 5.

With the help of a tab-shaped connecting element 12, the line sections 8 and 9 welded together near their free ends, so that these together with the connections 4 and 5 form a total of a so-called connection model 13, which is by welding is connected to the heating plate 2 in the area of the connections 4 and 5. The ends 14 and 15 of the line sections 8 and 9 are aligned parallel to one another and point with their opening cross-sections in the direction of the center line 10 of the heating plate 2. Die Ends 14 and 15 are a short distance apart and run in a lower one Edge area of the heating plate 2.

Depending on the further desired connection systems, the ends 14 and 15 of the line sections 8 and 9 with further line sections coupled to one another in pairs 16a, 16b, 16c connected according to FIGS. 2a to 2c. All line sections 16a to 16c have deflections of 90 ° at their free ends and are of length dimensioned so that the flow and return lines run symmetrically to the center line 10.

As an alternative to the line sections 16a to 10 angled in the region of the center line 10 16c is also the use of short, also angled line sections 17a to 17c 3a to 3c possible.

According to Fig. 4a, the flow is carried out via the connection 7 and the return via the connection 8, while the entire connection module 13, as described above, in this Version is unused. Therefore, all four opening cross sections are with corresponding Plug closed, which is shown in FIGS. 4a to 4d by an "X".

In the connection variant according to FIG. 4b, the flow takes place via connection 4 and Return via connection 5 of the connection module 13. The free ends 14 and 15 of the line sections 8 and 9 are closed with plugs as well as those on the other side arranged connections 7 and 8.

In the case of FIG. 4c, further line sections are at the free ends of the line sections 8 and 9 16c connected via which the flow and the return take place. All four corner connections 4 to 7 are closed.

The same as for Fig. 4c applies to Fig. 4d with the difference that the closure of the connection 4 not by a stopper, but by a valve 18.

This valve 18 is shown in more detail in FIG. 5 and as such from the prior art known, which is why further explanations are unnecessary.

5b illustrates how the valve 18 is inserted into the opening cross section 19 of the connection 4 can be.
