Description:

The innovation relates to a device for heat conduction for the supply and discharge and deflection area of underfloor heating, with system panels made of heat insulating material, which are used for the heating pipe routing are grooved.

The underfloor heating systems developed in recent years have one has a large number of advantages, particularly with regard to energy saving. With such a heater is a uniform and Favorable heat distribution causes the heat exchangers of the heating system to be invisible and therefore a spacious and free room design can be achieved because no annoying radiators have to be taken into account.

Of the known underfloor heating systems, the heating supplied with hot water has the further advantage that this with the
Normally already existing conventional boiler systems can be operated, regardless of the energy source used.

The underfloor heating system usually consists of system heat insulation panels Sait one the upper surface of the insulating plates several times continuous tube bed, which is designed in the form of mutually parallel grooves for receiving the heating tubes, which are preferably made of plastic. A heat conducting element is located between the insulating plate and the heating pipe for uniform heating Distribution of heat over the surface of the heat insulation panels. A film covering with a screed above completes the construction of the system.

In the previously known systems of this type, the deflection areas, d. H. the areas in which the heating pipes are returned in loops pose particular problems. In these areas are the heating pipes distributed unevenly over the surface, so that the resulting heat distribution is uneven. This problem was largely neglected so far.

The innovation is therefore based on the task of proposing heat conducting sheets, with the help of which a uniform heat distribution in the Deflection areas achieved \ idrd.

The solution to this problem consists in the fact that in the case of the device for heat conduction mentioned at the beginning, these are used as heat conducting plates with a pear-shaped circumference and a heating tube deflection guide running around the circumference and / or one running in the longitudinal axis of the surface Heating pipe groove are provided.

By shaping the heat conducting plate in this way, despite the uneven distribution of the heating pipes over the surface, a almost even distribution of heat is achieved. So that the deflection areas are fully included in the entire heating surface, so that a harmonious and even heat transfer is achieved.

In a further development of the invention, the heating tube deflection guide of the pear-shaped heat conducting plate is in the form of a heating tube that receives the heating tube Flare formed. The flanging of the pear-shaped heat conducting plate is in the concave circumferential area as a thermal expansion chamber educated.

In a modification of the invention, the heating pipe deflection guide of the pear-shaped heat conducting plate has a deep-drawn border.

The flanging or the deep-drawn border of a pear-shaped The heat conducting plate is designed as a thermal expansion chamber in the concave circumferential area with a large diameter, while the flanging or the deep-drawn border of a pear-shaped heat conducting sheet in the concave circumferential area with a small diameter as a flat tapering one Tongue is formed.

The flanging or the deep-drawn border of a pear-shaped Heat conducting plate forms in the circumferential area with an infinite diameter with a correspondingly subordinate heat conducting plate Heizrohrrille, so that the heating tube with the metal sheets a good one forms a thermally conductive connection.

Furthermore, the heat conducting sheet is designed as a compression-molded aluminum sheet and has a thickness of 0.4 - 1 mm.

In the deflection area, the heating medium shows the greatest cooling because the flow resistance is greatest in these areas. On the other hand, the heating pipes include a relative in their loop area large area, whereby the heating pipes are partly close to each other. In order to achieve a To achieve a uniform temperature distribution, a heat conducting sheet with a greater thickness is used according to the innovation.

The innovation is explained in more detail with reference to the drawing, in which an exemplary embodiment is shown.

Figure 1 shows the deflection area of a floor heating system in a room to be heated. On one made of insulating material System plate arrangement 1, which is provided with the required heating tube bed to accommodate the heating tubes, are the various heat conducting plates 2, 3, 4 assigned to one another accordingly for the deflection guide of the heating pipes. The heat conducting plate 2 is designed in the shape of a pear and has a heating tube deflecting guide 5 in the form of a flange receiving the heating tube or a deep-drawn border. the Flanging or deep-drawn border of the pear-shaped heat conducting plate 2 is in the concave peripheral area with a large diameter than Thermal expansion chamber 6 formed.

The linear expansion of the plastic heating pipes affects the deflection bends or comes into play there. For these reasons, the deflection area is designed as a thermal expansion chamber (6).
In the known systems, the heating pipes are firmly embedded in the screed, so that a compression load occurs in the deflection area that has hitherto been accepted, which disadvantageously resulted in unfavorable changes in the pipe cross-sections.

The thermal expansion chamber (6) after the innovation thus guarantees the Compliance with the inner pipe diameter over the entire service life of the plastic pipe, as it reduces the compression and expansion capacity of the Pipe does not hinder but allows over the entire length of the heating circuit.

The above-described flanging of the heat conducting plates (2) in the thermal expansion chamber (6) serves to increase the heat absorption of the resulting Heat build-up, as the heating pipe only has linear contact with the heat conducting sheet in this area, in particular when the heating tube moves to the outside of the thermal expansion chamber (6). Since the floor or the screed is heated, it serves this flanging or the deep-drawn border to the entire To improve heat management in this area.

Between two heat conducting plates 2 and 2 'there is a heat conduction Plate 3 arranged, the pear-shaped part 7 of which is arranged in the opposite direction to the pear-shaped parts of the heat conducting plates 2 and 2 ' is.

The heat conducting plates 3 are provided with a heating pipe groove 8 running parallel to the longitudinal axis of the surface 7, so that the heating pipe, which runs around the concave part of a heat conducting sheet 2 or 2 ", can be guided directly into the heating pipe groove 8.

FIG. 2 shows the assignment of heat conducting plates 2, 9 and 10 in alternating direction. The heating pipes are guided in serpentine lines around the pear-shaped heat conducting plates, so that kleir.a and the smallest rooms can be designed with a very good heat distribution. Each loop formed by a heating pipe is through a thermally conductive sheet filled, so that an even heat distribution is ensured.

From the cross section of a heat conducting sheet shown in FIG (2) the flaring or the deep-drawn border is without any further Explanations recognizable.
