Description

The The invention relates to a plate-shaped Device for receiving leads carrying a heat transfer fluid, with at least a carrier plate and with at least one of these at least partially covering the heat conduction made of thermally conductive Metal, wherein at least one heat conducting plate a partially arcuate having extending groove for receiving the heat conduction.

Out the prior art are generic plates for surface laying of piping for Heating or cooling purposes known, especially used in underfloor heating become. Such systems, in which the pipes below the Lastverteilschicht, in particular a screed arranged are and together with the plates one of these separate heating layer are also referred to as "dry systems". The support plate Such a device is usually by an insulating layer formed, which in particular polystyrene material, such as expandable Polystyrene material (EPS) can act. Furthermore, in the insulating layer a groove for receiving the groove of the heat conducting plate arranged above it formed, through which the pipeline is guided. On the laid Plates and piping is usually the arrangement of a separation layer provided on which the load distribution layer together with a Oberbelag is laid. In such a system structure are basically all Floor structures possible, In particular, it can be completely dispensed with a conventional screed be used or with dry knit plates.

In contrast, are also known as "wet systems", in which the pipelines completely be poured into the screed, and the screed a necessary Part of the overall system is. An advantage of such a wet system is that the complete circumference of the pipes as the heat transfer surface of the pipe is used to screed, while in a dry system construction without the arrangement of a heat conduction plate only a very small heat transfer surface to disposal stands, so that the latter is a mandatory component. Because of the design a complete enclosure of the Piping from the hot plates not possible is carried out in Trokkensystemen in contrast to wet systems the Recording of the heat output transported in the pipeline only along a part of the entire pipe surface.

This Disadvantage of using a drying system with a Wärmeleitblech is compensated by a faster removal of the Heating-cooling power due to the advantageous material properties of the heat conducting sheet, which is usually made of steel or aluminum. So is the specific thermal conductivity from screed about 1.0 to 1.8 W / mK while steel has a value of about 50 W / mK and the corresponding value of aluminum over 200 W / mK is located. However, it also plays the thickness of the heat conduction an essential role. Thus, e.g. Drying systems known at those with an aluminum foil with a thickness of 0.01 mm to 0.05 mm for receiving and removing the heating and cooling capacity be used. This is an advantageous use of the special Material properties not guaranteed.

One Another advantage of dry systems compared to wet systems consists in a more even flat Heat, which also to increase the heating or cooling capacity contributes to such a system. This disadvantage is in wet systems in general by a less spacing between the sections of the pipeline at the S-shaped Offset the same. While in the dry systems a spacing of the individual parallel sections of 25 cm in many cases is sufficient, in a wet system, a spacing of <15 cm to choose to the same space heating and cooling performance values to reach.

however is possible in both systems small spacing of the S-shaped arranged pipe section advantageous. In particular at conventional systems available on the market a laying distance of 25 cm or 12.5 cm provided. A reduction However, the pipe spacing is problematic, due to the to be provided deflection in an S-shaped installation of the pipeline. At the curvature of the Pipe in the arcuate extending portion of this deflection, which a curvature angle of 180 °, is one given minimum bending radius not to fall below, from the The reason is to avoid kinking of the pipes. This minimum Bending radius is conventionally five times Pipe diameter.

In conventional drying systems, therefore, a laying distance of <25 cm is difficult to implement. In particular, the arrangement of heat conducting plates, which extend not only over the rectilinear parallel sections of the pipeline, but also over the deflection, is not solved in known systems in the case of low installation distances. However, since the deflection area makes up a considerable part of the total surface area of the pipeline, the available heating or cooling capacity is insufficiently utilized, so that the above The advantages of a drying system in terms of performance advantage compared to a wet system are partially eliminated. For example, in a conventional drying system, the loss of the actually used heat absorption area on the pipeline can be 16.6% with a room width of 3 m. With a room width of 2 m and a resulting lower overall proportion of straight-line parallel pipe sections, the loss increases to 25% compared to the usable total heat or cooling capacity.

Of these, Based on the object of the invention, while avoiding the aforementioned disadvantages a dry system for laying pipelines in such a way that the available heating or cooling capacity is largely utilized, in particular the inclusion and the removal of heat or cooling capacity allows in the deflection becomes, without thereby restrictions in the choice of the laying distance of the pipeline or other disadvantages, such as putting up the pipeline in the deflection area, in purchase too take and still the construction-related effort as possible to keep low.

According to the invention said object with a device of the type mentioned by solved, that the groove in its arcuate section over a Angular range of more than 180 ° extends.

According to the invention is thus Direction of deflection of the line provided by a heat conduction plate with an Ω-shaped Groove is formed. This pronounced Ω shape makes the pipeline firmly held in the deflection and a raising of the line reliable avoided. In particular, in this embodiment, a curvature diameter achieved, the spacing of the rectilinear parallel sections exceeds the pipeline, so that according to the invention a lower Installation distance is feasible, while doing the prescribed minimum bending radius of the pipeline is taken into account. Because the Piping in an angular range of more than 180 ° from the heat conduction is surrounded, additionally follows an increase the heat absorption surface at the Piping compared to conventional systems.

According to preferred Further development of the plate-shaped device according to the invention is provided that at least one of the heat conducting plates with a groove having straight parallel sections. To reach a particularly high stabilization of the arcuate portion the groove forming the deflection area is suggested that the straight and the arcuate extending portions of the groove are formed in a heat conducting plate. For easy installation of the plates can also be provided that the arched ones and the straight portion of the groove in each case a heat conducting plate are formed, which together cover a carrier plate. After laying can the respective heat conducting plates in example firmly connected by mutual bonding together become.

A Cost minimization in the production of such installation panels can be achieved that two identically formed arcuate running Sections of the groove on each of a heat conduction plate side by side are arranged. For easy separation of the two identically formed sections It is suggested that between the two arcuate Sections in the heat conduction plate and in the carrier plate a predetermined breaking point is provided.

In Another preferred embodiment is provided that the carrier plate Having grooves for receiving the grooves in the Wärmeleitplatte. Thereby It is achieved that the pipe is completely in the plate-shaped device can be inserted and with the surface of the heat conduction comes to cover, so that a laying of the load distribution layer on the heating layer easily possible.

The Advantages of the device according to the invention Especially come to light when the straight sections the groove less than five times the diameter of the male line spaced apart are, since by the inventive Ω-shape of the Deflection range of the permissible minimum bending radius can still be met. For this purpose is the angular range of the arcuate extending portion of the groove chosen such that the smallest allowed Bending radius of the male line is not undershot. In a preferred embodiment, the groove extends in its arcuate running Section about an angular range between 180 ° and 270 °.

In Another preferred embodiment is provided that the heat conduction plate made of aluminum or steel, and a thickness between 0.3 mm and 1.0 mm. At this thickness, the high specific thermal conductivity The materials used are largely exploited. The thickness of the Overall arrangement, which by the carrier plate and the heat conducting plate is formed, it preferably has a thickness between 18 mm and 80 mm up.

To avoid corrosion between the pipe, which is formed for example by a copper pipe, and the heat conduction, It is proposed that a layer of corrosion-resistant material is provided on the heat-conducting plate at least at the region of the groove. This layer can be formed, for example, by a film of polyethylene (PE) adhering to the heat-conducting plate. A spatial separation between the line and the heat-conducting is achieved, for example, already at a thickness of the film of 0.2 mm.

The Production of an Ω-shaped Groove on the heat conduction plate can be achieved in a particularly simple and cost-effective manner, that the arcuate extending portion of the groove through a semicircular area and an area with two each at the ends of the semicircle subsequent essentially obliquely is formed against each other extending straight line. It can the obliquely angled Course of the straight line through an angle of at least 3 °, preferably of 7 °, with respect to the circle tangents at the respective end of the semicircle be formed. Alternatively, the arcuate section through be realized a single region of the groove, which a circle segment which covers an angular range of more than 180 °. The semicircular area itself can have an inner radius of 70 mm. In this case, the Slot advantageously a width of 10 mm and 30 mm, preferably 16 mm. Another concrete embodiment provides that the straight parallel extending sections less than 25 cm, preferably 12.5 cm from each other are spaced.

To the Reaching the required thermal insulation is provided that the carrier plate is formed of a material with low heat conduction. there it can be a material made of expandable polystyrene (EPS) or a polyurethane (PUR) material. Alternatively, you can it is also a material from a renewable resource.

A concrete embodiment provides that the device this one Width of substantially 50 cm and a length in a range of 50 cm to 150 cm. Preference is given to a length of 75 cm or 100 cm provided.

to Arrangement of the heat conducting plate on the carrier plate are two different embodiments conceivable. On the one hand, the heat conduction plate with the carrier plate already have a solid connection before laying, for example, by Sticking is achieved and already during the fabrication of the plates be performed can. On the other hand, the heat conduction of the carrier plate be designed separately to allow a separate laying.

following the invention with reference to preferred embodiments with reference closer to the drawings explains based on which further properties and advantages of the invention result. Show it:

1 a perspective view of a device according to the invention for receiving a heat transfer fluid lines leading;

2 a plan view of a device according to the invention according to 1 ,

The 1 shows in a schematic perspective view of the basic structure of a device according to the invention 1 for receiving a heat transfer fluid lines leading, which can be implemented, for example, advantageously in the floor of a building for heating or cooling of the floor, the wall or as Deckenheiz- and cooling system. For this purpose, the device 1 a carrier plate 2 made of heat-insulating material on. The surface of the carrier plate 2 is through two heat conducting plates 3.1 . 3.2 covered, which are formed of thermally conductive metal and along each one of its side edges in the width direction B along a connecting line 4 adjoin one another seamlessly, so that in turn a continuous flat overall surface is formed.

The surface of the heat conducting plates 3.1 . 3.2 has two identically shaped grooves in the form of U-shaped depressions, the thickness of which substantially corresponds to the thickness of the flat region of the heat conducting plates 3.1 . 3.2 corresponds and which are arranged side by side along the width direction B. The shape of each one of the grooves 5 . 6 along the flat surface of the heat conducting plates 3.1 . 3.2 essentially corresponds to the shape of an Ω, which by each three in the longitudinal direction L successively arranged portions of the grooves 5 . 6 is formed.

The first paragraph 5.1 . 6.1 the grooves 5 . 6 corresponds in each case two U-shaped recesses running essentially straight at a constant distance parallel to the longitudinal direction L, which extend through the total length of the heat conduction plate 3.1 through to the connection line 4 between the heat conducting plates 3.1 . 3.2 extend. At the connection line 4 come the pits of the first section 5.1 . 6.1 with corresponding recesses of the second section 5.2 . 6.2 the grooves 5 . 6 to cover. The latter are also rectilinear, but each have an increasing in the direction of extension spacing and finally open congruent in each case in the two ends of a semicircular U-shaped recess, the third section 5.3 . 6.3 the grooves 5 . 6 equivalent. The double inner radius 2R this Semicircle is greater than the distance A of the recesses in the first section 5.1 . 6.1 , wherein according to the invention the Ω-shaped course of the grooves 5 . 6 is achieved by the distance between the recesses in the second section 5.2 . 6.2 continuously increased by the difference between R and A.

On the symmetry axis between the grooves 5 . 6 is in the longitudinal direction L of the heat conducting plates 3.1 . 3.2 a breaking point 7.1 arranged and congruent thereto is another predetermined breaking point 7.2 on the support plate underneath 2 provided, if necessary, a simple separation of the device 1 in two identical parts, each with a groove 5 . 6 to enable.

The 2 shows a plan view of in 1 shown device, wherein again the oblique course of the recesses of the grooves 5 . 6 in the second section 5.2 . 6.2 It is illustrated, which in this Ausführungsbei play an angle of 7 ° with respect to the Kreistangenten at the ends of the third section 5.3 . 6.3 equivalent.

Thus, through the sections 5.2 and 5.3 respectively. 6.2 and 6.3 the groove 5 respectively. 6 an arcuate course of the groove 5 . 6 guaranteed by more than 180 °. This has the advantage that through the groove 5 . 6 even at a small distance A of the recesses in the first section 5.1 . 6.1 a line can be performed without losing the minimum bend radius to be maintained such a line in the third section 5.3 . 6.3 to fall below, for example, which corresponds to five times the diameter of the line. As a result, for example, a laying distance A of a line can be realized which corresponds to a standard of 12.5 cm or at least falls below a distance of 25 cm. Due to the pronounced Ω-shape of the groove 5 . 6 the line gets stuck in the first section 5.1 . 6.1 with the small spacing A held between the recesses and the stresses that arise during the bending of the conduit in the first section 5.1 . 6.1 collected. Because after laying the heat conducting plates 3.1 . 3.2 a fixed connection between the two heat conducting plates is provided, is also a displacement of the heat conducting 3.2 upwards due to the in the section 5.2 and 5.3 occurring voltages of the line excluded. In an alternative embodiment, the heat conducting plates 3.1 . 3.2 also be designed as a single piece.
