Definitions

  • the invention relates to a pipe distributor with a flow chamber and a return chamber, which are arranged one above the other and are rectangular in cross section, in particular for district heating.
  • Pipe distributors are used for heating systems and other piping systems. In heating systems, they are used to connect the supply lines and the return lines. They are also often used as heating circuit distributors for underfloor heating.
  • a pipe distributor which consists of a flow chamber and a return chamber, to which several connecting pieces are connected.
  • This known pipe distributor has a common horizontal partition that divides the pipe distributor into a flow chamber and a return chamber.
  • the heat exchange that occurs in this pipe distributor between the flow chamber and the return chamber heats the heat transfer medium in the return chamber.
  • heat transfer from the feed chamber to the return chamber should be largely avoided. This could be achieved in a simple manner in that these two chambers are arranged next to one another in a completely separate manner, as was previously customary in heating systems. At a Such an arrangement inevitably results in cumbersome, long cable runs which, on the one hand, entail energy losses and also represent a high cost of materials.
  • the invention has for its object to provide a pipe distributor in which heat exchange between the flow chamber and the return chamber is largely avoided.
  • the pipe distributor designed according to the invention takes up little space and prevents the heat transfer medium from heating up in the return chamber. Since flow temperatures of approx. 130 ° C occur in district heating systems and at the same time return temperatures of max. 50 ° C are to be maintained, the pipe distributor according to the invention is particularly suitable for use in district heating systems.
  • the insulating layer consists of a rigid foam that mechanically connects the flow chamber and the return chamber.
  • additional connecting means between the flow chamber and the return chamber can be dispensed with in most cases.
  • additional connecting elements can be provided.
  • the R ear manifold can be designed to achieve a higher mechanical stability so that one or more spacer elements are inserted into the intermediate space between the flow chamber and return chamber, via which the two chambers are mechanically interconnected.
  • a particularly preferred embodiment provides that the pipe distributor has connecting pieces, of which at least one connecting piece (7) is passed through one of the chambers. This measure results in particularly favorable conditions for the connection of the return lines and supply lines. The result is a clear arrangement for the valves placed on the pipe distributor and long, lossy pipe branches are avoided.
  • the pipe distributor according to the invention can furthermore be designed such that bushings are provided in one of the chambers, the inside diameter of which is larger than the outside diameter of the connecting pieces passed through it. In this way, heat exchange between the connecting pieces carried out and the chamber through which these connecting pieces are passed is avoided.
  • the pipe distributor can be designed so that between there is a free space between the bushings and the connecting pieces.
  • a further development provides that an insulating material is introduced into the intermediate space.
  • This insulating material may contribute to an even firmer mechanical connection between the two chambers there is, must be used as without ß additional fasteners. Such a better mechanical connection results if the intermediate space is foamed with hard foam, for example.
  • the pipe distributor can also be designed such that one or more centering elements are inserted between the bushing and the associated connecting pieces. These can be designed as rings which are placed on the connecting piece.
  • a further development provides that ribs or other elevations are formed as centering elements on the connecting piece.
  • centering elements are only necessary if, due to the design of the pipe distributor, centering without centering elements is not possible. This may be the case if there is only a very small space between the bushing and the connecting piece.
  • the pipe distributor according to the invention shown in Fig. 1 consists essentially of a flow chamber 1, a return chamber 2 and an intermediate insulating layer 3.
  • the two chambers 1, 2 are not only connected to each other by the insulating layer 3, but it is also an End plate 4 provided. Such an end plate can also be attached to the end, not shown in the drawing.
  • spacer elements 5 can also be used, which are inserted at certain intervals between the two chambers 1 and 2.
  • Such a spacer 5 is shown in the drawing, which can be welded or soldered to the flow chamber 1 and the return chamber 2.
  • the insulating layer 3 can be glued to the opposite surfaces a and b.
  • the space between the flow chamber 1 and the return chamber 2 is foamed by means of a rigid foam, which creates a sufficiently stable connection between the above-mentioned chambers 1 and 2 during hardening.
  • connection pieces 6, 7 of the pipe distributor shown are attached so that they protrude on one side of the pipe distributor.
  • connection piece 7, which lead to the return chamber 2, through the flow chamber 1 carried out.
  • feedthroughs 8 are formed in the flow chamber 1, which have a larger inner diameter than the outer diameter of the connecting pieces 7 passed through them. A space thus arises between the connecting piece 7 and the leadthrough 8 This space can be free, so that there is no connection between the flow chamber 1 and the connecting piece 7.
  • the intermediate space can also be filled with foam, as shown in FIG. 2.
  • insulating layer 3 and the insulating material introduced between connecting piece 7 and flow chamber 1 can consist of hard foam, which is introduced in one operation by foaming.
  • spacer elements 9 can be placed on the connecting piece 7.
  • the spacer 9 consists of a ring placed on a connecting piece 7. This ring is preferably made of heat-insulating material.
  • spacer elements are not shown in the drawing.
  • Such spacer elements can also be ribs or other elevations formed on the connecting piece 7. It should only be ensured that these molded spacers rest on the inner wall of the bushing 8 with the smallest possible area in order to largely prevent heat transfer between the flow chamber 1 and the connecting piece 7.
