Heating system having at least one electrothermal heating layer, a structural component having such a heating layer, a heating method and a method for producing a semi-finished component or a component having a heating device

摘要

A heating system including an energy supply device, wherein the heating system includes a base heating device having an insulation layer, with an electrothermal base heating layer arranged thereon and with an electrical connecting device by way of which the energy supply device is connected to the base heating layer. The heating system includes an additional heating device having an insulation layer, with an electrothermal additional heating layer arranged thereon and with an electrical connecting device by way of which the energy supply device is connected to the additional heating layer. The energy supply device is connected to the heating layers by way of the connecting devices and in the activation phase, current is supplied during at least a partial period of time to the additional heating layer so that the base heating layer generates heat permanently, while the additional heating layer generates heat in the partial period of time.

1. A structural component comprising a heating system with at least one energy supply device, wherein the heating system comprises:
a base heating device comprising an insulation layer, with an electrothermal base heating layer arranged thereon which comprises at least one bundle of rovings, or at least one compound structure of rovings, or at least one ribbon of rovings, and with an electrical connecting device connecting at least one energy supply device to the base heating layer, wherein the ends of each roving in each case are connected to an electrode of the electrical connecting device, an additional heating device comprising an insulation layer with an electrothermal additional heating layer arranged thereon which comprises at least one bundle of rovings, or at least one compound structure of rovings, or at least one ribbon of rovings, and with an electrical connecting device connecting the energy supply device to the additional heating layer thereby providing a cohesive heating effect, the base heating device and the additional heating device are spatially associated with each other, and in this arrangement the energy supply device is designed in such a manner that in an activation phase current is supplied during at least a partial period of time to the additional heating layer to heat the structural component in the region of the additional heating layer to a setpoint temperature, and that, above and beyond the activation phase, current is continuously supplied to the base heating layer so that the base heating layer generates heat continuously during operation of the heating system, while the additional heating layer generates heat in the partial period of time.
