Abstract

Method and arrangement for providing a cooled cable duct which is intended for fitting in hot environments in vehicles and in which cabling can be laid to protect it against heat. The cable duct (1) includes a plurality of longitudinal sections (2, 3) in which a first section (2) is intended to support one or more cabling(s) and in which a second section (3) is intended for connection to an external cooling system so that a cooling medium can pass through the at least one said second section (3).

Claims

1. A cable duct (1) for a motor vehicle, comprising:

a plurality of metal longitudinal sections (2,3) comprising a first section (2) configured to support at least one cabling and at least one second section (3) connected to said first section (2) in heat-conducting relationship therewith and configured to be connected to an external cooling system, said at least one second section (3) including a pressure-tight conduit extending through it whereby a pressurized cooling medium pass through and be contained within the at least one second section (3), the cable duct (1) being sized and configured to be installed within the engine compartment of the motor vehicle.

2. The cable duct as recited in claim 1, wherein the first section (2) is divided into a plurality of subsections (5a, 5b) and each subsection is intended to support a cabling.

3. The cable duct as recited in claim 1, wherein the first section (2) comprises at least one fastening device for said cabling.

4. The cable duct as recited in claim 1, wherein an opening between outer walls (7a, 7b) in the first section (2) or between an outer wall (7a, 7b) and a partition wall (7c) in a subsection (5a, 5b) is less than the cross section of the cabling to be installed in the section or sub-section.

5. The cable duct as recited in claim 1, wherein the second section (3) is divided into a plurality of subsections (6a, 6b) in which at least one subsection (6a) is intended as a supply conduit and at least one subsection (6b) is intended as a return conduit for the cooling medium.

6. The cable duct as recited in claim 1, wherein the cable duct comprises at least one integrated fastening device (4) for fixing the cable duct (1) to another element.

7. The cable duct as recited in claim 1, wherein the cable duct comprises at least one integrated fastening device (4) for fixing a component to the cable duct (1).

8. The cable duct as recited in claim 1, wherein the cable duct (1) is configured as an extruded profile made of one of (1) an aluminum alloy and (2) a composite.

9. The cable duct as recited in claim 1, wherein the cable duct (1) is configured as a die-cast part made of one of (1) an aluminum alloy and (2) a composite.

10. The cable duct as recited in claim 1, wherein the first section (2) comprises a detachable element (8) forming a connection between outer walls (7a, 7b) of the first section.

11. The cable duct as recited in claim 1, wherein the first section (2) comprises at least one closed duct (9a, 9b).

12. The cable duct as recited in claim 1, wherein the first section (2) is divided into a plurality of subsections (5a, 5b) in which each of said subsections is configured to support a cable therein and wherein the first section (2) has at least one fastening device for said cable.

13. The cable duct as recited in claim 1, wherein the first section (2) has an open configuration to permit cabling to be supported by the cable duct to be pressed laterally into said first section (2) and secured therein.
