  • the front heating plate of the known heating device is often later provided with a covering, for example by clamping or gluing.
  • Such heating devices such as are presented for example in DE 38 38 513.9 AI, also have the disadvantage that the production of such a heating device is complex, since a large amount of energy is required to press the sheets and then watertight to one another over a large area ver welding. The requirement for large-area welding also results in a relatively large number of leaks, and consequently reworking of correspondingly defective radiators is required. Radiators that cannot be reworked also occur. The inspection of the weld seams in a water basin is also required on a regular basis and means a further work step which considerably increases the production costs of the known heating device. In addition, known radiators of this type are in need of improvement in terms of their compressive strength
  • known plate heating elements function to a large extent by the emission of convection heat, ie air rising on the plate heating element is heated and distributed via the movement in a room of a building to be heated. This dry warm air is for the Ge
  • the health of the occupants is usually disadvantageous, especially since dust is whirled up by convection heat. It is therefore preferable to use a radiator that works at least predominantly with radiant heat, since the radiant heat gives the occupants of a building a pleasant warmth at the same time as the room temperature is low, while there is no fear of excessive air movement and therefore dust generation.
  • radiators such as Gheder radiators
  • Gheder radiators can only be manufactured with an even greater amount of work and energy, and work with an even greater proportion of convection heat output.
  • radiators have become known which are arranged in the form of base heating strips in the floor area of the premises of a building. This type of radiator also works largely with convection heat. Due to the small surface area of such a radiator, it essentially works with convection heat and only to a small extent with direct or indirect radiant heat. The direct radiant heat is emitted by the small areas of the plinth heating strips that face the room. A larger part of the radiant heat is generated in that the rising hot air heats the wall areas above the base heating strip, whereby the walls become heat radiators and the radiation area of the base heating strips is indirectly increased.
  • the effectiveness of such known radiators is questionable and the air flow rising from the floor, which sweeps the walls of a building, ensures that the walls become unsightly after a short time due to the separation of dirt particles, such as dust and the like.

  • the line has heat exchange surface, particularly in the form of pipes, heat exchangers, so that the heat supplied by the heating medium via the heat radiation surface is radiant heat can be delivered.
  • the large-area contact of the line on the heat radiation surface results in an effective heat transfer and the provision of only a very narrow gap keeps the heat transfer reproducibly in an advantageous range.
  • the use of a separate line or a separate pipe ensures that no leakage test is required in order to be able to release the ultimately produced heating or cooling element for sale, since lines and in particular pipes can be made regularly tight.
  • a heating or cooling element according to the invention can be produced with only about 15 components, while about 30 parts are required for the assembly of conventional plate heating elements. This also makes it clear how much cheaper a heating or Heat sink to manufacture according to the present invention and how much less Such a heating or cooling element (hereinafter referred to only as a heating element) is susceptible, since fewer assembly errors can occur with the arrangement of a smaller number of parts
  • the profiling preferably encompasses the line, in particular the pipeline, under tension. As a result, an even more improved heat transfer between the line and the heat radiation surface can be created.
  • the outer diameter can be up to 0.5 mm, preferably up to about 0.3 mm, larger than the inside diameter of the profile
  • the profiling in the heat radiation surface can be connected to the line by welding, soldering, gluing or the like. It is important to ensure that the heat transfer resulting from this justifies the technical connection effort, i.e. there is an improved heat transfer compared to the previous design standards.

  • the diameter of the pipeline is preferably somewhat larger than the inner diameter made available by the profiling, which is stamped or stamped into the sheet of the heat radiation surface. Because the line is advantageously mechanically less stable than the heat radiation surface or its profiling, the line, in particular the pipeline, can adapt particularly well to the profile by deforming, so that the heat transfer can be significantly improved.
  • the radiator according to the invention can be provided with a convection body, which can be placed on the heat radiation surface on the line side.

This embodiment makes it possible to provide a heating or cooling body with a particularly small overall depth.
