Embodiment Construction

[0061] For the foregoing and especially the following description, it should be clearly emphasized that the present invention is not limited to the embodiments and is not limited to all or more features of the combination of technical features described here. Rather, this / each embodiment Each individual component feature (for example, referred to as a favorable parameter range for a particular material) can also be disconnected from all other features, thereby, the component feature itself and any other embodiment. Combinations of features are all inventive.

[0062] as first by figure 1 As follows, the heatable fluid conduit 1 according to the invention has at least one line 2 and at least one electrically heating conductor 3 extending at least over a partial region of the length L of the line. The heating conductor 3 , which may in particular be a stranded wire, is only shown as a highly simplified zigzag line. The heating conductor can surround the cylindrical surface of ...

Abstract

The invention relates to a heatable fluid line (1) comprising at least one pipeline (2, 218) and at least one electrical heating conductor (3, 224) extending over at least a partial section of the length (L) of the pipeline. In order that the fluid line (1) fulfills increased requirements in respect of resistance to high temperatures, compensation of pressure pulsations and / or compression resistance, while being less complex to produce and assemble and / or connect, according to the invention the pipeline (2, 218) has at least two longitudinal sections (2a, 202, 2b, 204) which are designed differently in respect of the material properties and / or design thereof, namely at least one first longitudinal section (2a, 202) which consists of a first material which comprises a first polymer and a second longitudinal section (2b, 204); which consists of a second material which comprises a second polymer, wherein the material of the second longitudinal section (2b, 204) is more flexible and / or has a higher resilience than the material of the first longitudinal section (2a, 202). The described method for producing such a fluid line according to the invention relates to an adaptive attachment of the heating conductor (3, 224) on the outside of the pipeline (2, 218) which permits the heating conductor (3, 224) to be wound around fluid coupling and / or connector parts, in particular the housings thereof (14, 15, 16, 17, 21, 22, 33, 34, 50, 51, 52, 53, 206, 208, 210, 212, 230, 232, 244, 246) by means of which the line (1) is assembled, without strand separation.

Description

technical field [0001] The invention relates to a heatable fluid conduit comprising at least one pipeline and at least one electrically heating conductor extending over at least part of the length of the pipeline. Furthermore, the invention relates to a method for the production of such bundled fluid conduits and their use. Background technique [0002] Bundling (konfektionieren) or making (konfektion) of conduits (konfektionieren) is understood here to be the final stage of the manufacturing process of the fluid conduit that completes the installation, after this stage, conduit can (for example according to customer's request) as equipped with such as fluid coupling piece and / or or conduit connectors and can be industrially preferably used in motor vehicle technology. [0003] Heatable fluid conduits have been disclosed in various forms and are applicable, for example, to automotive fluid distribution systems. The fluid can be, for example, water for a window washer syste...
