Abstract

An at least partially heatable line-connector for a media line which can be heated, the line-connector at least partially including a thermally-conductive or thermally-conducting material, with a heating system and/or heating elements being associated outside the body of the line-connector. An assembled media line with at least one heatable media line is provided with at least one such at least partially heatable line-connector.

First claim

What is claimed is:

1. An at least partially heatable pipeline connector for a heatable media pipeline, wherein the pipeline connector comprises: a thermally conductive or heat-conducting material, wherein a heating system and/or heating elements are assigned outside of a body of the pipeline connector, wherein the pipeline connector has a through opening for conveyance of a medium through the pipeline connector, wherein the thermally conductive or heat-conductive material is present in a first region of the through opening, wherein a second region of the pipeline connector does not consist of the thermally conductive or heat-conducting material, wherein no heating elements are provided in the body of the pipeline connector, wherein the pipeline connector comprises at least one guide apparatus on an external surface of the pipeline connector for fixing or guiding a heating element on the pipeline connector, wherein the pipeline connector further comprises an insulating apparatus at least partially surrounding the pipeline connector for thermal insulation incorporating at least one air volume for thermal insulation, wherein the thermally conductive material is a thermally conductive plastic, wherein the thermally conductive plastic has a thermal conductivity of 1 to 20 W/(m·K), and wherein the pipeline connector is constructed as one part having multiple permanently connected components including the first region as one component and the second region as a second component.

2. The pipeline connector according to claim 1 , wherein the pipeline connector has at least one part constructed as a connection section, in a plug-like manner, wherein the thermally conductive or heat-conducting material is provided at least in a region of the connection section.

3. The pipeline connector according to claim 1 , wherein the pipeline connector comprises at least one thermally conductive or heat-conducting sleeve component, which is connected to the same.

4. The pipeline connector according to claim 1 , wherein the insulating apparatus is provided in the region of a connecting section for connecting to a plug or the media pipeline.

5. The pipeline connector according to claim 1 , wherein the pipeline connector is constructed in such a manner that heat can be coupled into the pipeline connector in a radial direction by an apparatus for heat coupling.

6. The pipeline connector according to claim 1 , wherein the pipeline connector is advantageously provided with a wall thickness of 1 to 20 mm for axial thermal transport.

7. The pipeline connector according to claim 1 , wherein the pipeline connector is provided with at least one fastening component and/or guide component for an external arrangement of heating elements and for improving an introduction of heat.

8. An assembled media pipeline with at least one heatable media pipeline and with at least one at least partially heatable pipeline connector according to claim 1 .

9. The assembled media pipeline according to claim 8 , wherein the thermally conductive or heat-conducting material of the pipeline connector is a material which conducts heat better than a material or at least one of the materials of the media pipeline.

10. The assembled media pipeline according to claim 8 , wherein the media pipeline is also provided with at least one heating element, extending continuously along the media with at least one heating wire.

11. The assembled media pipeline according to claim 8 , wherein the media pipeline comprises at least one layer made up of a conductive or conducting plastic provided with contacting components.

12. The assembled media pipeline according to claim 10 wherein at least one heating strand, is arranged in a region of the pipeline connector.

13. The assembled media pipeline according to claim 12 , wherein in a case of a provision of one heating strand, the same extends continuously along the media pipeline and the at least one pipeline connector, in a case of a provision of two heating strands, both extend along the media pipeline and at least one of the two heating strands is provided for wrapping the pipeline connector, in a case of a provision of four heating strands, two heating strands extend along the media pipeline and two heating strands are provided for wrapping the pipeline connectors.

14. The pipeline connector according to claim 1 , wherein the thermally conductive plastic has a thermal conductivity of 1 to 7 W/(m·K).

15. The pipeline connector according to claim 6 , wherein the pipeline connector is advantageously provided with a wall thickness of 2 to 5 mm for axial thermal transport.

16. The pipeline connector according to claim 3 , wherein the pipeline connector is constructed as a two-component injection moulding, insertion part or press-in part and is connected to the sleeve component.

17. The pipeline connector according to claim 4 , wherein the insulating apparatus is provided in the region of a fastening clip.

18. The pipeline connector according to claim 1 , wherein a connection section connectable to the media pipe is constructed including a laser-transparent material.

19. The pipeline connector according to claim 7 , wherein the at least one fastening component and/or guide component has a ribbed structure.

20. The pipeline connector according to claim 11 , wherein the layer made up of a conductive or conducting plastic has heating elements for heating a plastic.

21. The pipeline connector according to claim 12 , wherein a different number of heating strands are arranged in one region of the pipeline connector as compared to another region of the pipeline connector.
