Definitions

  • the invention relates to a radiator, in particular a tubular radiator, from a plurality of similar basic elements arranged laterally next to one another and connected to one another in a fluid-tight and gas-tight manner at their hub-like head and foot region, forming an overflow opening, one of which in each case one of the basic elements in the foot region with a connecting piece for the Flow and on the other hand the return is provided and at least the basic element provided with the connecting piece for the forward flow is arranged between other basic elements, this connecting piece being connected to the foot region of the basic element arranged at the end in each case by means of a dip tube which extends through the overflow openings of the intermediate basic bodies and merely is sealed off from the overflow opening between the end-side base element and the base element adjacent to it.
  • Radiators of the type described above are known for example from DE-U1-295 02 860.2. They can be assembled from any number of similar basic elements according to the desired heating output, with the possibility of arranging the preferably adjacent connections for the flow and return not at one end of the radiator, but in the central area of the radiator.
  • a curved immersion tube which connects the connecting piece for the flow to the hub-like foot region of the base element at the end in each case, in order to ensure that the heat-emitting medium firstly heats the radiator in the region of the end Flows through the basic element, in which the radiator valve designed as a manually operated or thermostatic valve is usually also arranged.
  • the invention is accordingly based on the object of further developing a radiator of the type described at the outset, in particular as a tubular radiator, in such a way that the immersion tube required in each case can be easily assembled and reliably sealed with the least possible storage.
  • the immersion tube is designed as a straight tube and is inserted at one end by means of a liquid-tight plug connection into a lateral opening of the connecting piece projecting into the hub-like foot region of the respective basic element.
  • dip tubes each designed as a straight tube, these can either be easily provided in different lengths or cut to length from larger tube pieces in a simple manner. Since the dip tube is inserted at one end by means of a liquid-tight plug-in connection into a lateral opening of the connecting piece, which for this purpose protrudes into the hub-like foot area of the respective base element, simple assembly is obtained by simply inserting the dip tube from the end of the radiator . In this way, not only is inventory reduced, but assembly is also simplified.
  • a seal sealing the end of the dip tube against the interior of the connecting piece is used, which is preferably made of permanently elastic material.
  • the connecting piece is designed as a sleeve provided with a lateral opening, which is inserted into an opening in the hub-like foot region of the base element and is preferably welded in here.
  • the bushing is advantageously designed as a component provided with a blind hole and provided with an internally threaded section for connecting the flow.
  • the seal is also preferably designed as a sealing sleeve.
  • the connecting piece is designed as a pipe bend, the one end of which, preferably with an internal thread, is inserted into an opening in the hub-like foot region of the base element and the other end of which is provided with the plug connection for the immersion pipe.
  • the immersion tube can be designed either with a circular or a polygonal, for example hexagonal, cross section.
  • the immersion tube in its end position forming a liquid-tight plug connection in the connecting piece, it can be provided according to a further feature of the invention at the front end with a threaded section which engages in a corresponding internal thread of the connecting piece. So that the dip tube with its threaded section can be screwed into the internal thread of the connecting piece in a simple manner, according to a further feature of the invention, it is provided with key surfaces for a tool at the rear end, for example with recesses provided in the end face. If the dip tube is designed with a polygonal cross section, the inner surface or the outer surface of the dip tube end can be used as a key surface.
  • the invention further proposes to pass the immersion tube in the region of the overflow opening between the end element and the base element adjacent to it through a sealing washer, which seals the jacket seals the dip tube against the overflow opening.
  • This sealing washer is preferably made of permanently elastic material.
  • FIG. 1 and 2 show the foot region of five similar basic elements G1 to G5, which are connected to one another in a liquid-tight and gas-tight manner at their hub-like foot region to form an overflow opening U, for example by directly welding the edges forming the overflow openings U.
  • a closure plug VS is inserted in its outer end face.
  • one of the basic elements G in the exemplary embodiments the basic element G4, is provided with a bushing 1, which is designed as a component provided with a blind hole and a lateral opening 1a having.
  • the immersion tube 2 penetrates the overflow openings U of the basic elements G2 and G3 lying between the basic elements G1 and G4 in such a way that the overflow openings U are retained for the transfer of the heat-emitting medium.
  • the immersion tube 2 is guided through a sealing disk 3, which seals the jacket of the immersion tube 2 against the base elements G1 and G2 and thus closes the overflow opening U.
  • This sealing washer 3 is preferably made of permanently elastic material.
  • connection-side end of the dip tube 2 which is designed as a straight tube, is inserted into the lateral opening 1 a of the sleeve 1 by means of a liquid-tight plug connection.
  • this liquid-tight plug connection consists of a sealing bush 4 made of permanently elastic material, which is inserted into the blind hole of the bush 1 in such a way that it seals with its lateral surface on the one hand against the blind hole and sealingly encloses the dip tube jacket with a lateral opening 4a. In this way, the medium entering the sleeve 1 serving as the connecting piece A is reliably passed on to the foot region of the basic element G1.
  • connection piece A is used, which is designed as a pipe bend 5.
  • the one end of the pipe bend 5 inserted into an opening in the hub-like foot region of the base element G4 is in turn provided with an internally threaded section 5b for connecting the heating flow; the other end of the pipe bend 5 also has an internal thread 5a in the exemplary embodiment.
  • the front end of an immersion tube 2 is inserted, which is drawn again in the side view and in the end view in FIGS. 3 and 4.
  • the immersion tube 2 is designed with a hexagonal cross section and is provided at the front end with a threaded section 2a which can be screwed into the internal thread 5a of the pipe bend 5, with the interposition of a seal 4 forming the plug connection , which is designed in the embodiment of FIG. 2 as an O-ring.
  • the threaded connection serves to secure the plug connection formed by the seal 4.
  • a tool for example a socket wrench with an external hexagon or hexagon socket, which interacts with the outer surface or inner surface of the hexagonal cross section of the dip tube 2, in particular Fig. 4 reveals.
  • FIG. 5 shows a further embodiment of a dip tube 2, which is also provided with a threaded section 2a, but has a circular cross section.
  • a dip tube 2 which is also provided with a threaded section 2a, but has a circular cross section.
  • key surfaces 2b are formed, so that this immersion tube 2 can also be inserted into the connecting piece A with a suitable tool and secured there by turning in the end position of the plug connection.
  • a dip tube 2 with the corresponding Length can either be taken from the warehouse or separated from a pipe of greater length.
