Definitions

the invention relates to an electrical heating conductor, which consists in the form of a stranded conductor of a plurality of stranded, copper and steel-containing wires ( DE 41 24 684 A1 ).
Such a heating element is used for example in surface heating elements and in particular in heaters of seats of cars. He is subject in particular in a seat heating constantly changing mechanical loads.
the heating element must therefore be flexible but also tensile and resistant to bending, so that a equipped with the same heating element has a sufficiently long life.
a heating wire which is composed of individual wires, which are constructed in the form of a mixed strand of steel and copper.
several heater wires are electrically connected in parallel and cold pressed at their ends with individual conductors, which are arranged in the edge regions of the surface heating element.
individual conductors which are arranged in the edge regions of the surface heating element.
the invention has for its object to make the initially described heating element so that it can be installed as a single element in a heated surface and survives mechanical alternating loads permanently unscathed.
the heat conductor constructed in the specified frame made of copper and steel satisfies all mechanical requirements, in particular because of the higher proportion of steel compared to copper. He is well bendable because of the strand construction, but also tensile and bending resistant.
By suitable variation of the proportions of copper and steel it is easily possible to set different values for the electrical resistance of the heating conductor without impairing its mechanical properties. It can be arranged as a single element on or in any areas and only has to be connected at its ends to a voltage source. Since each of the copper wires is surrounded by a preferably applied by painting insulating, it is also ensured that caused by different chemical potentials corrosion can not occur. It can also occur no so-called "hot spots" with a selectively increased electrical resistance and correspondingly increased heat development.
a section of a heating element H is shown schematically, having an electrically conductive core 1 and a surrounding casing 2 made of temperature-resistant insulating material.
the shell 2 can also be omitted with appropriate processing of the heating element H at the site.
the core 1 is made of copper wires and steel wires, for example, as follows:
central element 4 is arranged, which is surrounded by units 5, in which a plurality of steel wires 6 are stranded together.
the units 5 are stranded with the central element 4.
the diameter of the respective individual wires made of copper or steel can advantageously be between 0.01 mm and 0.1 mm.
the soul 1 consists, according to the basic representation in Fig. 2 , in a preferred embodiment of a central element 4 and six stranded around the same units 5. These seven stranding - central element 4 and 5 units - have all advantageously the same diameter, so that there is a symmetrically constructed soul 1.
each of the stranding elements 4 and 5 twelve wires are stranded together in a preferred embodiment.
Each of the copper wires 3 of the central element 4 is surrounded by an insulating layer 7, which is preferably applied by painting.
an insulating layer 7 As a material for the insulating layer 7, a lacquer based on polyurethane is preferably used. The thickness of the insulating layer 7 is for example 4 microns.
the copper wires 3 are insulated by the insulating layers 7 with respect to the surrounding steel wires 6, so that no chemically induced corrosion between the different wires can occur.
the steel wires 6 of the units 5 as well as the copper wires 3 can all be provided with an insulating layer surrounding them.
On the separate outer shell 2 ( Fig. 1 ) can be dispensed with in such an embodiment of the heating element H.
the heating conductor H or its core 1 has an electrical resistance of 500 ohms / km, with a steel content of 85% and a copper content of 15%. It can be set to values between 100 ohms / km and 1000 ohms / km by appropriate variation of the proportions of copper and steel. For this purpose, the proportion of steel on the heating element 1 between 60% and 90% can be changed, whereby analogously, the proportion of copper between 40% and 10%.
