Abstract

A line arrangement comprising an electrical line which has at least one electrical insulator and at least one electrical conductor which runs at least in some sections adjacently to the electrical insulator along a longitudinal axis of the electrical line. The line arrangement additionally has a passive heat dissipator which runs at least in some sections along the longitudinal axis and which has at least one heat-absorbing surface portion and at least one heat-emitting surface portion thermally connected to the heat-absorbing surface portion. The heat-absorbing surface portion is brought towards the electrical conductor at least to such an extent that the heat-absorbing surface portion forms a thermally operative connection to the electrical conductor in order to dissipate waste heat from the electrical conductor to the heat-emitting surface portion.

First claim

What is claimed is:

1. A line arrangement comprising:
an electrical line which has at least one electrical insulator and at least one electrical conductor which runs at least in some sections adjacently to the electrical insulator along a longitudinal axis of the electrical line, and
a passive heat dissipator which runs at least in some sections along the longitudinal axis and which has at least one heat-absorbing surface portion and at least one heat-emitting surface portion thermally connected to the heat-absorbing surface portion,
wherein the heat-absorbing surface portion is brought towards the electrical conductor at least to such an extent that the heat-absorbing surface portion enters into a thermally operative connection to the electrical conductor in order to dissipate waste heat of the electrical conductor to the heat-emitting surface portion,

wherein the heat dissipator has a plurality of lugs spaced from one another along the longitudinal axis, which form the heat-emitting surface portion, and which branch laterally from the at least one heat-absorbing surface portion,
wherein the heat-absorbing surface portion of the heat conductor extends along the longitudinal axis at least substantially over the entire length of the electrical conductor.

2. The line arrangement according to claim 1 , wherein the at least one electrical insulator
a) is formed as an electrically insulating encasement, wherein the at least one electrical conductor runs at least in some sections along the longitudinal axis inside the electrically insulating encasement; and/or
b) is formed as an electrically insulating spacer element, wherein at least two of the electrical conductors are spaced apart from one another by means of the electrically insulating spacer element.

3. The line arrangement according to claim 1 , wherein the heat dissipator is formed of a flat, elongate material and runs at least substantially plane-parallel to an outer surface of the electrical conductor.

4. The line arrangement according to claim 1 , wherein the heat-absorbing surface portion and the heat-emitting surface portion are arranged relative to one another in such a way that a heat path which forms between the surface portions and along which the waste heat of the electrical conductor is dissipated runs at an angle to the longitudinal axis.

5. The line arrangement according to claim 4 , wherein the angle is a right angle to the longitudinal axis.

6. The line arrangement according to claim 1 , wherein the heat-absorbing surface portion of the heat dissipator runs at least substantially inside the electrical insulator.

7. The line arrangement according to claim 6 , wherein the heat-absorbing surface portion of the heat dissipator:
a) runs inside the electrically insulating encasement; and/or
b) runs inside the electrically insulating spacer element.

8. The line arrangement according to claim 1 , wherein the heat-emitting surface portion of the heat dissipator is led laterally out of the electrical insulator.

9. The line arrangement according to claim 8 , wherein the heat dissipator is led laterally out of the electrically insulating encasement and/or laterally out of the electrically insulating spacer element.

10. The line arrangement according to claim 1 , wherein the heat-emitting surface portion has at least one connection region which is designed to connect the heat-emitting surface portion heat-conductively to a heat sink.

11. The line arrangement according to claim 1 , wherein the heat-emitting surface portion forms cooling fins.

12. The line arrangement according to claim 1 , wherein the heat-emitting surface portion has a heat-emitting layer with an emissivity greater than the emissivity of the material of the heat dissipator itself.

13. The line arrangement according to claim 1 , wherein the at least one electrical conductor is formed as an elongate flat conductor with a flat cross section.

14. The line arrangement according to claim 1 , further comprising at least one fastening means for mechanically fastening the electrical line to an adjacent structure.

15. The line arrangement according to claim 14 , wherein the electrical line is mechanically fastened to the heat sink.

16. A connection arrangement having two electrical connectors for electrical connection to a corresponding electrical device, and a line arrangement according to claim 1 , wherein the electrical connectors are each electrically connected to the at least one electrical conductor of the line arrangement, and are arranged at opposite ends of the line arrangement along the longitudinal axis.

17. An energy transmission system having the connection arrangement according to claim 16 , wherein
a) the first electrical device of the two electrical devices is formed as a primary electrical energy source; and wherein
b) the second electrical device of the two electrical devices is designed as an electrical consumer.

18. The energy transmission system of claim 17 , wherein the primary electric source is an accumulator, accumulator group or charging device for charging accumulators, and the electrical consumer is as an electric motor, or as a secondary energy source, comprised of an accumulator or accumulator group.

19. A line arrangement comprising:
an electrical line which has at least one electrical insulator and at least one electrical conductor which runs at least in some sections adjacently to the electrical insulator along a longitudinal axis of the electrical line,
a passive heat dissipator which runs at least in some sections along the longitudinal axis and which has at least one heat-absorbing surface portion and at least one heat-emitting surface portion thermally connected to the heat-absorbing surface portion,
wherein the heat-absorbing surface portion is brought towards the electrical conductor at least to such an extent that the heat-absorbing surface portion enters into a thermally operative connection to the electrical conductor in order to dissipate waste heat of the electrical conductor to the heat-emitting surface portion,

wherein the heat dissipator has a plurality of lugs spaced from one another along the longitudinal axis, which form the heat-emitting surface portion, and which branch laterally from the at least one heat-absorbing surface portion, and
wherein the at least one electrical conductor is formed as an elongate flat conductor with a flat cross section.
