Description

Tubular radiators

Description

The invention relates to a tubular radiator with several horizontal pipes arranged one above the other, which are connected at their ends to vertical distributor pipes on both sides, with the flow and return connections being arranged on a horizontal pipe and a riser pipe running in a vertical distributor pipe. It is known to insert an inner pipe in one of the vertical distributor pipes, with the lower end of the pipe being connected directly to the flow connection.

A tubular radiator of the generic type is known from DE 198 00 487 A1, which has an inner pipe in one of the side distributor pipes, which extends to the upper end of the distributor pipe and is connected to the flow connection, wherein the inner pipe has an opening in the pipe jacket in a lower area, through which the inside of the inner pipe is connected to the lowest horizontal pipe designed as a connection pipe. Between the inner pipe and the vertical distributor pipe, a partition wall is arranged above the opening, which seals the space surrounding the opening from the rest of the radiator volume. Furthermore, a partition wall is inserted between the flow and return connections arranged on the lowest horizontal pipe within the connection pipe in order to prevent flow in the pipe between these two connections. If the flow and return connections are arranged on the same horizontal connection pipe of the radiator, the function of the radiator is not guaranteed without such an interruption in flow.

The object of the invention is to improve a radiator of the type mentioned at the outset with regard to its connection construction in relation to a variably designed central connection to be provided on a horizontal pipe.

This object is achieved according to the invention in that the riser pipe is arranged in a lower horizontal pipe, preferably in the lowest horizontal pipe, and is connected at one end to the heating medium

provided flow connection, with the other pipe end directed towards the vertical distributor pipe. Advantageously, with such a riser pipe, the heating medium is guided in a surprisingly simple manner directly from the connection area of the radiator to the desired entry point in the radiator. According to a preferred feature of the invention, the riser pipe begins in the lower horizontal pipe at the connection flange for the heating medium flow, which can be connected on both the right and the left. The riser pipe can thus be installed or converted for flow on the "right" instead of the "left".

According to a special feature of the invention, the riser pipe runs with one end into the vertical distributor pipe and has an upwardly directed deflection bend there for deflecting the heating medium, whereby the deflection bend or the pipe end of the horizontal pipe is also designed as a nozzle according to a further feature for better distribution. A further embodiment of the invention consists in that a vertical inner riser pipe is arranged in a vertical distributor pipe, which has an opening arranged in the pipe jacket in a lower area through which the inner vertical riser pipe is connected to the riser pipe running in the horizontal pipe.

It is also advantageous that the connection flange and the riser pipe can form a coherent component or can also be designed as composable pipe sections and/or T-pieces and/or bends and connection parts.

The inner tubes can be made entirely or partially from hose material and/or flexible tubes, allowing for easy assembly or disassembly.

An embodiment of the invention is shown in the drawings and is described in more detail below. In the drawings,

Figure 1 shows a tubular radiator with several horizontal pipes 1 arranged one above the other, which are connected at their ends on both sides to vertical distributor pipes 2, T , with the flow and return connections 3, 4 being arranged on a horizontal pipe 1\. The flow and return connections 3, 4 are preferably designed as a central connection. The riser pipe 5 is preferably arranged in the lower horizontal pipe V and is connected to the flow connection 3 provided for the heating medium or the connection flange 6. The other end of the pipe is directed towards the vertical distributor pipe T. The riser pipe 5 can be of different lengths and can extend into the vertical distributor pipe T. The end of the riser pipe can also be closed as shown in Figure 1, in which case an upwardly directed opening is provided on the pipe jacket. The heating medium is thus guided in the simplest way via the horizontal riser pipe 5 directly into the vertical distributor pipe 2'. Figure 2 shows a similar radiator. The riser pipe 5 ends here with a deflection bend 5" in the vertical distribution pipe 2\. The deflection bend 5' or the pipe edge of the horizontal riser pipe 5 can also be designed as a nozzle for better distribution of the heating medium.

According to Figure 3, the riser pipe end can also be located at the top of the vertical distributor pipe &idiagr;.

Figure 4 shows a tubular radiator with a composite riser pipe. In the vertical distributor pipe 2", a vertical inner riser pipe 5* ^x is arranged, which has an opening 7 arranged in the pipe jacket in a lower area, through which the vertical inner riser pipe 5" is connected to the horizontal riser pipe 5' running in the horizontal pipe V.

The connection flange 6 and the riser pipe 5 can form a continuous component or can be designed as assemblable pipe sections and/or T-pieces and/or bends and connecting parts. The inner pipes 5, 5\

5" may consist entirely or partially of hose material and/or flexible pipes.

The supply and return connections 3, 4 are preferably designed as central connections.
