- ECGs have at least one inductive component.
- the inductive component is, for example, a choke coil or a transformer.
- the inductive component has a wire winding.
- the wire winding has a number of turns of an electrical conductor for generating a magnetic flux through the current flowing in the conductor.
- the wire winding also serves to generate a voltage by changing the magnetic induction in the wire winding.
- the wire winding is usually on a core with ferromagnetic material.
- the ferro magnetic core material is, for example, a ferrite. The core ensures that the magnetic circuit is as closed as possible.
- a small size of an inductive component can be achieved with a constant power throughput by a higher switching frequency.
- a higher switching frequency leads to an increase in electrical losses and thus to one
- the quality is a measure of an electrical quality of the inductive Component.
- a cooling device for cooling the wire winding is implemented with a cooling circuit which is operated with the aid of a fluid.
- the miniaturized inductive component is normally operated in an air environment. This means that the wire winding of the component is cooled solely by convection, which is caused by the ambient air.
- this type of cooling may not be sufficient to reduce the operating temperature to such an extent that the quality of the inductive component meets the requirements.
- the object of the present invention is to provide an inductive component with an efficient cooling device for cooling the wire winding.
- an inductive component for forming a magnetic circuit which has at least one wire winding and at least one cooling device for cooling the wire winding.
- the inductive component is characterized in that the cooling device has at least one composite material with at least one polymer material and at least one thermally conductive filler.
- the composite material preferably consists of an electrically insulating or electrically poorly conductive polymer material with a thermally conductive and electrically poorly conductive filler.
- the Polymer material can have a natural and / or artificial polymer.
- the natural polymer is, for example, rubber.
- the artificial polymer is a plastic.
- the polymer material forms a matrix in which the filler is embedded.
- the filler can be powdery or fibrous.
- a diameter of a filler particle is selected from the ⁇ m range, which ranges from 100 nm to 100 ⁇ m.
- a fill level of the filler in the polymer material is preferably selected so that a coagulation limit is exceeded. Below the coagulation limit, the likelihood of individual filler particles touching is very low. This leads to a relatively low specific
- the filler is thermally conductive and preferably also electrically insulating or electrically poorly conductive.
- the operating voltage is up to 2000 V.
- the composite material also has a breakdown test at an operating voltage of this magnitude.
- a ceramic material is particularly suitable as a thermally conductive and at the same time electrically insulating or electrically poorly conductive filler.
- a ceramic material with the properties mentioned is, for example, aluminum oxide (AI2O3).
- the composite material of the cooling device is preferably connected directly to the wire winding. Heat is transported away from the wire winding by heat conduction.
- the cooling device has at least one film with the composite material which is in direct, thermally conductive contact with the wire winding.
- the film and the wire winding are connected in such a way that heat conduction from the wire winding to the film can take place.
- the foil and the wire winding touch each other.
- a film thickness (film thickness) of the film is, for example, 0.22 mm.
- a specific thermal conductivity coefficient ⁇ of 0.15 K / Wm up to 6.5 K / Wm can be achieved.
- the dielectric strength can be 1 kV to 6 kV despite the relatively small film thickness.
- a soft film with the composite material is used.
- the film is plastically and / or elastically deformable.

- the composite material and the further composite material can be the same or different. The same applies to individual components of the composite material and the other composite material.
- the wire winding and / or the film are partly or completely in the sealing compound with the other Composite embedded. Since the other composite material is thermally conductive and the embedding provides an almost complete positive connection between the casting compound and the wire winding or film, the heat can be dissipated very efficiently from the wire winding and the film via the casting compound.
- the use of the potting compound also results in a homogeneous temperature distribution within the inductive component.
- the wire winding of the component is cooled homogeneously. This also contributes to an increased quality of the inductive component.
- an intermediate space present between the film and the wire winding and / or between the encapsulation and the wire winding has a thermally conductive material for thermally bridging the intermediate space.
- the intermediate space is preferably completely filled with the thermally conductive material. This leads to improved heat dissipation away from the wire winding.
- a thermally conductive material is preferably used for this purpose, which is additionally electrically insulating. The thermally conductive material is therefore selected in particular from the group of oil, paste, wax and / or adhesive.
- the cooling device of the inductive component is designed such that the in the wire winding during operation of the inductive component heat can be efficiently dissipated to the outside.
- the heat is transported away from the composite material of the cooling device.

- the fluid is, for example, a liquid or a gas or gas mixture.
- the heat is preferably carried on
- the film with the composite material and / or the sealing compound with the composite material is therefore thermally conductively connected to a heat sink in the inductive component by heat conduction.
- the heat sink ensures that the smallest possible temperature difference between the wire winding, the cooling device and the heat sink is present during operation of the inductive component.
- the heat sink is preferably designed such that it can absorb a large amount of heat.
- the heat capacity of the heat sink is large. It is also conceivable that the heat sink ensures efficient removal of the heat.
- the heat sink is, for example, a heat sink made of a material that is characterized by a high thermal conductivity.
- Thermal gradients can be used to cool the heat sink by convection.
- the inductive component is preferably a choke coil or a transformer.
- a choke coil is permeable to direct current. In contrast, alternating current is limited by the choke coil.
- the choke coil has a high electrical reactance for a current of high frequency.
- the transformer consists of at least two wire windings. However, more than two wire windings can also be used
- Transformer made of a wire winding, which is divided into two parts by an electrical tap.
- the inductive component is used in an electronic ballast in which an electrical input power is converted into an electrical output power. Input power and output power are usually different.
- the component is operated with an alternating voltage with a frequency in the range from 100 kHz up to and including 200 MHz. This frequency range is called the high frequency range.
- the inductive component has in particular a core with a ferromagnetic core material that is suitable for high frequencies.
- the core material is a ferrite in the form of an M33 core material with a cutoff frequency of approximately 10 MHz.
- This core material contains manganese and zinc.
- a Kl, K ⁇ or K12 core material is also conceivable. These core materials have nickel and zinc.
- core material has a cut-off frequency of 7 MHz.
- the wire winding advantageously has a high-frequency stranded wire with a large number of individual wires which are electrically insulated from one another.
- a strand is a wire that is wound or braided from many metal threads (single wires).
- the individual wires are insulated from one another in order to reduce losses due to the skin effect and eddy currents.
- a lower high-frequency loss resistance is achieved in comparison to a stranded wire with individual wires that are not insulated from one another with the same cross section.
- the individual wires have at least one individual wire diameter selected from the range from 10 ⁇ m to 50 ⁇ m inclusive.
- the variety is in the range from 10 to including 30 selected.
- 10 or more individual wires are arranged to form a high-frequency strand. This makes it possible to provide wire windings with a relatively large surface area and thus with a relatively low high-frequency loss resistance.
- an AC voltage of up to 2000 volts is used. It has been shown that the gap can be used to achieve high quality even at a few hundred volts with a frequency of a few MHz. This means that the inductive component can be miniaturized and still a high power throughput can be achieved with high quality and low internal losses.
- the inductive component can thus be referred to as a miniaturized HF-HV (high-frequency high-voltage) component.
- the inductive component can also be used in an ignition transformer to ignite a discharge lamp.
- the discharge lamp is controlled by an electrical circuit with a high alternating voltage (initial voltage).
- a voltage pulse with an AC voltage of up to 40 kV is therefore used.
- the component is briefly driven with this high alternating voltage within a few ⁇ m (ignition duration).
- the invention has the following significant advantages:
- the heat generated in the wire winding during operation of the inductive component can be efficiently dissipated.
- the efficient heat dissipation leads to a relatively small increase in the temperature of the wire winding.
- the small increase in temperature leads to a relatively small increase in the electrical resistance in the Wire winding. The result is an increased quality of the inductive component compared to an uncooled wire winding.
- the use of the potting compound also results in a homogeneous temperature distribution within the inductive component.
- the wire winding of the component is cooled homogeneously. This also contributes to an increased quality of the inductive component.

- FIG. 4 shows a section of an inductive component with a cooling device in a lateral cross section.

- the component 1 has a wire winding 3 and a core 4.
- the wire winding is characterized by a winding axis 12, along which the wire of the wire winding 3 is wound.
- the Wire winding 3 is a high-frequency strand 14 with 30 individual wires.
- the wire diameter of a single wire is about 30 ⁇ m.
- the core 4 is a ferrite core and consists of an M33 core material.
- the core has an RM6 core shape (FIGS. 6a and 6b).

- the core 4 has a core-center gap 7, which is arranged around the central bore 15 in the inner region 10 of the wire winding 3. Two further gaps 8 are in the outer region 11 of the wire winding 3 in each of the core legs 6 of the
- the core is essentially symmetrical. It consists of two parts 5 arranged mirror-symmetrically to the mirror plane 13, which are arranged opposite one another at the columns 7 and 8 and are spaced apart from one another by the gap widths 9.
- the mirror plane 13 is located in the three columns 7 and 8.
- the wire winding 3 is arranged essentially symmetrically by the arrangement. The result is an inductive component which is essentially symmetrical to the mirror plane 13.
- the wire winding 3 is cooled.
- a cooling device 20 for cooling the wire winding 3 is provided.
- the cooling device 20 has a film 21 with a thermally conductive composite material.
- the base material of the composite material is a thermally and electrically poorly conductive polymer material.
- a filler with high thermal and low electrical conductivity is embedded in the polymer material.
- the film 21 has a film thickness of approximately 0.22 mm.
- the specific thermal conductivity coefficient ⁇ is about 4 K / Wm.
- the electrical dielectric strength extends up to about 6 kV.
- the high-frequency strand 14 of the wire winding 3 and the film 21 are wound around a winding body 30 adapted to the RM6 core shape.
- the film 21 and the wire winding 3 are arranged around the winding body 30 in such a way that the high-frequency strand 14 of the wire winding 3 and the films 21 alternate in a radial direction starting from the winding body 30 (FIGS. 1 and 2).
- the film 21 used serves as an intermediate insulation layer of the high-frequency stranded wire 14 of the wire winding 3. This results in an efficient heat conduction path 24 away from the wire winding 3 in the radial direction.
- Heat which arises during operation of the inductive component in the high-frequency strand 14, is efficiently dissipated along the heat-conducting path 24.
- the high-frequency braid 14 of the wire winding 3 and a plurality of foils 21 are each individually radially aligned with the winding body 30 (FIG. 3).
- a multi-chamber solution is implemented, which is also referred to as a disk winding. An efficient dissipation of the heat via the heat conduction path 24 is also ensured here.

- the potting compound 22 is in direct thermal contact with part of the wire winding 3. This means that the heat can be dissipated via heat conduction via a thermal contact surface between the high-frequency license 14 of the wire winding 3 and the film 21 or the films 21.
- the casting compound 22 is connected to the heat sink 25 in a thermally conductive manner via heat conduction.

- the heat is transferred from the foils 21 or the wire winding 3 in the direction of the heat sink 25 via the dissipation fin 26, which is connected to the foils 21 via a spacer ceramic 28 with a relatively high thermal conductivity coefficient.
- gaps 27 which reduce the efficiency with which the wire winding 3 is cooled (FIG. 4).
- these intermediate spaces 27 are filled with a thermally conductive and electrically insulating or poorly conductive paste.
