Definitions

  • the invention relates to a radiator, preferably a radiant ceiling panel, consisting of a plurality of adjacent heat exchange elements connected in parallel on the fluid side and / or one behind the other, the inflow and outflow of which are connected to a continuous collecting line, in which, for dividing the collecting line into individual line sections, elastic separating plugs, preferably made of rubber or plastic.
  • Such heat bodies are known in particular as radiant ceiling panels. They are composed of several heat exchange elements of the same type, which are connected on the inflow and outflow sides to a respective continuous collecting line.
  • separating plugs are arranged, on the one hand to avoid a short circuit between the inflow and outflow of the heating medium flowing through the heating element if the inflow and outflow are connected to the same collecting line, and on the other hand to divide the collecting lines into individual line sections if the heat exchange elements forming the heating element form several exchange surfaces lying next to one another, but through which flow flows in the opposite direction.
  • the separating plugs which are preferably made of rubber or plastic, are produced with outer dimensions that are slightly larger than the inner dimensions of the collecting pipe, into which the separating plugs are inserted.
  • the separating plugs are non-positively fixed in the manifolds. Since the elasticity of the separating plugs wears off over time, especially since the separating plugs are also exposed to an aggressive heat medium, it cannot be ruled out that, particularly at high flow velocities, displacements of the separating plugs occur within the collecting lines. Such displacements change the distribution of the heat medium within the heat exchange elements, which can be associated with a considerable reduction in the heat output. In addition, such shifts are not recognizable from the outside without destroying the manifolds.
  • the invention has for its object to develop heat bodies of the type defined in such a way that undesired displacements of the separating plugs are prevented.
  • the solution to this problem by the invention is characterized in that the separating plugs are positively fixed against displacement in the manifold by stop surfaces formed in the interior of the manifold. This prevents undesired displacements of the separating plugs that are not visible from the outside.
  • the stop surfaces can be formed by indentations in the wall of the collecting line. These indentations are applied after the separating plugs have been placed in the respective position within the manifold. The type of indentation depends on the cross-section of the manifold.
  • the stop surfaces can be formed by a pin which is inserted into a bore penetrating at least one wall of the collecting line and at least part of the separating plug. This pin is at least at one end with the Welded manifold.
  • the inside diameter of the bore in the separating plug can be made slightly smaller than the outside diameter of the pin, so that by inserting the pin into the separating plug there is an expansion of the separating plug, which leads to a closer contact of the separating plug with the wall of the Bus line leads.
  • FIG. 1 shows a total of 12 examples of heat radiators designed as radiant ceiling panels, each of which is made from two or more identical heat exchange elements 1.
  • All heat exchange elements 1 of a heat body are connected at their two ends to common manifolds 2, which consequently run over the entire respective width of the heat body.
  • stop surfaces are formed inside the respective collecting line 2, which fix the respective separating plug 3 in a form-fitting manner against displacement in the collecting line 2.
  • FIG. 2 shows a perspective view of a first exemplary embodiment of a manifold 2 with a rectangular cross section based on a partial length of this manifold 2.
  • the separating plug 3 inserted into this manifold 2 can be seen in broken lines. It is held in the respectively predetermined position by indentations 4, which are formed in the exemplary embodiment according to FIG. 2 in two adjacent corners of the collecting line 2 after the separating plug 3 has reached its predetermined one Position in the manifold 2 has been brought.
  • These indentations 4 form stop surfaces for the separating plug 3 in the interior of the collecting line 2, so that the latter cannot shift even at higher flow speeds and higher pressures and despite aging of the separating plug 3 which occurs over time.
  • FIG. 3 shows a manifold 2 which is circular in cross section and in which a correspondingly cylindrical separating plug 3 is arranged. This separating plug 3 is also positively fixed in its predetermined position by indentations 4.
  • the third exemplary embodiment according to FIG. 4 shows the section of a collecting pipe 2 with a triangular cross section, into which a corresponding triangular separating plug 3 is inserted.
  • the separating plug 3 is positively fixed by a single indentation 4 which is formed in one of the three surfaces of the collecting line 2 as soon as the separating plug 3 has assumed the predetermined position in the collecting line 2.
  • FIG. 5 shows an alternative embodiment of the stop faces for the form-fitting fixing of the separating plugs 3 in a perspective illustration corresponding to FIG. 2 of a section of a collecting line 2 with a rectangular cross section a hole is inserted in one of the four walls of the collecting line 2 and protrudes into a hole 3a in the separating plug 3.
  • the pin 5 is welded to the manifold 2, as indicated in Fig. 5.
  • This pin 5 also forms stop surfaces within the manifold 2, which form-fit the separating plug 3 at its predetermined position hold the manifold 2. If the inside diameter of the bore 3a is made slightly smaller than the outside diameter of the pin 5, the insertion of the pin 5 into the separating plug 3 also results in an expansion of the separating plug 3, which increases the sealing effect.
  • the heat bodies can be formed from any number of heat exchange elements 1, the cross section of the manifolds 2 used here also being arbitrary.
  • the heat exchange elements 1 and manifolds 2 can consist of metal, preferably steel or stainless steel, but also of suitable plastic.
  • the elastic separating plugs 3 are preferably made of rubber or plastic.
