Abstract
A heating-wire device. The heating-wire device includes at least one heating wire, a heating region, which comprises the at least one heating wire embedded therein and can be heated by the heating wire; a current source, which is connected to the heating wire and is configured to apply a current to the heating wire and heat it; a controller, using which the current source can be controlled; a first adhesion-promoting layer, which is arranged on a surface of the heating wire and surrounds the surface thereof, wherein the heating region surrounds the first adhesion-promoting layer.
Claims7
A heating-wire device, comprising:
- at least one heating wire;
- a heating region which includes the at least one heating wire embedded therein, the heating region being heatable by the heating wire;
- a current source, which is connected to the heating wire and is configured to apply a current to the heating wire and heat it;
- a controller configured to control the current source;
- a first adhesion-promoting layer arranged on a surface of the heating wire and surrounding the surface of the heating wire, wherein the heating region surrounds the first adhesion-promoting layer;
- and
- a sheath and a second adhesion-promoting layer, wherein the sheath surrounds the first adhesion-promoting layer and the second adhesion-promoting layer surrounds the sheath, wherein an outer region of the heating region is applied to the sheath so as to embed it therein.
A method for producing a heating-wire device, comprising the following steps:
- providing at least one heating wire;
- embedding the heating wire in a heating region, wherein a first adhesion-promoting layer is arranged on a surface of the heating wire and surrounds the surface of the heating wire, wherein the heating region surrounds the first adhesion-promoting layer;
- providing a current source, which is connected to the heating wire and is configured to apply a current to the heating wire and heat it;
- and
- providing a controller configured to control the current source,
- wherein a sheath is sprayed onto the first adhesion-promoting layer and a second adhesion-promoting layer is applied to the sheath, wherein the second adhesion-promoting layer is melted at least in some regions when it is arranged on the sheath and wherein an outer region of the heating region is applied to the second adhesion-promoting layer so as to embed it therein.
