Abstract

The object of the invention is to provide a sheet-like, electrical resistance heating network which, for example in the building sector, is integrated as a floor and wall panel heating element directly on the surface of the plastered structure, and consequently can be used as an infrared heater. The sheet-like, electrical resistance heating network (1) consists of individual heating filaments (2), for example polymer-carbon filaments, polymer-silver filaments or carbon filaments, which are laid in parallel at a distance from one another in the longitudinal direction, and insulating filaments (3), for example glass filaments or polymer filaments, that are laid at right angles thereto likewise in parallel at a distance from one another in the transverse direction. The heating filaments (2) and the insulating filaments (3) thereby form a network with preferably square openings. At the beginning and the end of the resistance heating network (1) there is an electrode (4), consisting of a metal wire or metal strip of a low resistance, respectively arranged in the transverse direction over the entire width of the network, and the two electrodes (4) lie parallel to one another and are electrically connected to the underlying heating filaments (2). The processed heating filaments (2) may have different resistance values. This dictates the heat that is generated by the resistance heating network (1) or individual portions of the heating panel. In a variant, the transversely lying insulating filaments (3) are at least partially replaced by heating filaments (2).

Description

Surface, electrical resistance heating network

Surface, electrical Wider Standsheiznetz preferably for use as surface heating in construction.

There are already a variety of solutions known to use the planar laid electrical conductors for heating purposes. Thus, in the document DE 69 014 841 T2 an electrical

Against Standsheiznetz described from thin metal wires.

This is a heating glazing with at least two rigid glass panes in particular. Between the two discs is a yielding

Interlayer. Between a disc and the resilient intermediate layer, the electrical resistance heating network is arranged. Furthermore, power supply belts are arranged. The intermediate layer supporting the wire heating net allows the intermediate layer to slide with respect to the underlying rigid disc. In DE 10 2010 011 102 AI a heating device for an interior of a vehicle is described, which has a net-like fabric element. The fabric element has electrical heating conductors and is as surface radiator

educated .

In the document DE 198 16 816 AI is an electrical

heatable surface heating element with an electric

non-conductive ground tissue described. In the base fabric electrically conductive contact conductor and heating conductors are involved, wherein the heating conductors between the spaced-apart contact conductor wavy or meandering shaped

run next to each other and have a relation to the distance of the contact conductor greater length. The heating conductors

touch each other over their length in several places

adjacent heating conductors electrically conductive and thereby form a

Heating network. The heating conductors are preferably made of carbon fibers or carbon-coated threads. The object of the invention is to provide a planar, electrical Wider Standsheiznetz, which, for example, in

Construction as a floor and Wandheizflächenelement is integrated directly into the surface of the plaster body and thus can be used as infrared heating.

The innovative design of the Wider Standsheiznetzes guarantees the functionality even with partial

Destruction, such as in the production of

Drilled holes through the Wider Standsheiznetzes. The

Attachment of the Wider Standsheiznetzes is also possible directly on the plaster surface or concrete surface and can be used here at the same time as a structural upper surface. Of the

Structure construction of the Wider Standsheiznetzes with its

preferably rectangular openings allows one

Exchange between room air and masonry.

Advantageous embodiments of the invention are in the

Claims 2 to 10 shown.

With several electrodes resting parallel on the network, different heating surface sections are produced according to claim 2. This can be achieved by different controls

different heating effects are achieved.

According to claim 3 are lying in the transverse direction

Insulating yarns at least partially replaced by filaments and / or partially replaced by the filaments lying in the longitudinal direction by insulation threads. This results in a wide range of different strong heating power. Furthermore, in the event of damage to the heating network, for example as a result of a hole made through the heating network, the overall effect of the heating network is not impaired. This makes processing in the building industry ideal. Due to the electrical connection of the individual heating filaments, there is a flow of current around the damaged area. The omission of individual filaments, which are replaced by insulation threads, resulting in more or less wide strips without heating within the Heating network. By this measure a variety of requirements can be realized on the heating network.

By the arrangement of the electrodes described in claim 4, an advantageous control of the heating power is achieved.

The arrangement of the electrodes can be repeated several times according to claim 5 on the heating network. As a result, can produce surfaces under different heating power.

According to claim 6, the electrodes can

Polymer fiber fabric bands exist and in the edges of the

Heating net be woven. This eliminates the costly application and contacting the electrodes with the heating network.

By introducing filaments of various kinds

Resistance according to claim 7 can very different

Services of the heating network are produced.

By laminating the heating networks according to claim 8, the heating power of the heating network can be increased. The same is achieved in the lamination, but here eliminates the advantage of many breakthroughs in the heating network. According to claim 9, the complete heating network with a

Be surrounded isolation layer. This will all

sensitive contact points of the electrical conductors in particular protected against aggressive media of the environment. The use of the inventive Wider Standsheiznetzes is given according to claim 10, preferably in construction. This makes it possible to realize interesting solutions for electrical heating in the floor or wall area.

Several embodiments of the invention are in the

Drawings are shown below and become closer

described. Show it: Fig. 1 is an electrical Wider Standsheiznetz with parallel filaments and this at right angles parallel insulation threads, wherein the heating filaments and the

Insulation threads form a square pattern,

Fig. 2 is an electrical Wider Standsheiznetz with parallel filaments, which also by also

parallel heating filaments are crossed,

Fig. 4 shows the arrangement of the electrodes on a

Wider Standsheiznetz with parallel filaments and transverse insulation threads,

Fig. 5 shows a possible arrangement of the electrodes on a

Wider Standsheiznetz with parallel filaments and this at right angles parallel insulating threads, thus forming an open grid and the electrodes at the beginning and end of the heating network, both connected by a running at the edge of the heating network connecting electrode and a central electrode, the no connection owns to the other electrodes and

Fig. 6 is a heating network with woven electrodes and longitudinal and transverse filaments, wherein the transverse filaments are spaced by two intermediate insulating threads and an indicated hole and the current flowing around it. The planar, electrical resistance heater network 1 consists of individual spaced parallel in the longitudinal direction

laid filaments 2. In the transverse direction, ie at right angles to the heating filaments 2, are also spaced parallel

Insulation threads 3. The heating filaments 2 consist for example of polymer carbon filaments, polymer filaments or carbon filaments. The insulation threads 3 are made of glass fibers or

Polymer threads. The filaments 1 form with the insulation threads 2 a grid, which is normally open. The heating filaments 1 and the insulation threads 2 thus have a net-like

Structure. The grid preferably has a size between 0.5 cm by 0.5 cm to 1 cm by 1 cm. The grid does not have to be executed square. For power supply, the heating network has electrodes 4. These electrodes 4 are normally opposite at the beginning and end of the heating network 1 in parallel. The electrodes 4 consist of a metal wire or metal strip with good electrical conductivity and have a good electrical contact with lying below the electrodes 4

Filaments 2.

However, other electrodes 5 are conceivable. These

Electrodes 5 are made of conductive

Polymer fiber fabric tapes and can be woven into the heating network with.

In another Ausführungsar t of the Wider Standsheiznetzes 1 lying in the transverse direction insulation threads 3 are replaced by filaments 2 or partially replaced. This results in a net-like arrangement of the filaments 2. In a laying of this heating network 1 on the surface of a

Masonry or concrete wall or on the surface of a

Floor retains the heating network 1 even in case of damage, such as, for example, made through holes, his

Operability. By the crosswise laying of the

Filaments 2 and the electrical contact with each other a fault in the heating network 1 is flowed around by the stream. This is a significant advantage of this embodiment.

The arrangement of the electrodes 4 can also be from the above

deviate variant described. For example, a

Connecting electrode 4.1 may be provided between the initially located electrode 4 and the end electrode 4, which is preferably laid on the edge of the heating network 1. These three electrodes 4 are electrically interconnected

connected. In the middle between the electrode 4 at the beginning and the electrode 4 at the end of the heating network 1 is another

Electrode 4, but no connection to the

Connecting electrode 4 has. The different ones

Electrode patterns can be repeated several times on the heating network 1. With the different arrangement of Electrodes 4 a variety of heating effects can be achieved.

According to the desired heating effect of the

Against Standsheiznetzes 1 filaments 2 can

different resistance values in the heating network. 1

be incorporated. So z. B. that in Figure 6

Resistance Standsheiznetz 1 shown following resistance values: the heating filaments 2 as electrically conductive weft threads from 10 kohm / running meter to 200 kohm / running meter with a weight numbering of up to 110 tex,

the heating filaments 2.1 as electrically conductive warp threads of 30 ohms / linear meter. up to 800 ohms / running meter with a weight numbering of 14 tex to 110 tex and

the electrode 5 with electrically conductive warp threads and

Weft threads of 0.5 ohms / meter. up to 15 ohms / running meter at a

Weight numbering from 44 tex to 110 tex.

Two or more Wider Standsheiznetze 1 can be superimposed and laminated with each other. But it can also be two or more Wider Standsheiznetze 1 laminated together. By this measure, the heating power of

Against stand heating networks 1 can be increased.

A further advantageous variant of the Wider Standsheiznetzes 1 is given by the fact that the individual heating filaments 2,

Insulation threads 3 and the electrodes 4 with a

Insulation layer are surrounded, z. B. a rubber layer.

Through the insulating layer in particular the

Contact points between the individual heating filaments 2 and the electrodes 4 are particularly protected. Thus, for example, without insulation protection processed heating networks 1 can get faster corrosion at the electrical contact points.

In a further variant, individual heating filaments 2 can be omitted in the Wider Standsheiznetz 1 and through

Insulation threads 3 are replaced and thus more or less wide strips without filaments 2 in the heating network 1 are generated.

Thus, 1 areas are generated in the heating network, without

Heating power are. The inventively designed Wider Standsheiznetze 1 are preferably used in construction. Here they are called

Surface heating in the floor and wall area find application and act here preferably as infrared heating. Its net-like structure provides a good connection between masonry and indoor air.
