1Temperature

If large line cross sections are used to transmit high electrical power, then heat input into the line arrangement is kept low, but material requirements increase and cost increases, and weight increases

Engineering Contradiction:

Core Design Contradiction:
TemperatureVSQuantity of substance

Solution Approach 1:

The patent changes the thermal conductivity parameter of the line arrangement by incorporating heat dissipators with high thermal conductivity (such as aluminum or copper) into the electrical line structure. This allows efficient heat removal from the conductors, enabling the use of smaller cross-section conductors while maintaining acceptable temperature levels during high power transmission.

Solution Approach 1:

The patent implements a passive heat dissipation system where heat dissipators are integrated directly into the electrical line structure. These heat dissipators automatically conduct heat away from the conductors through thermal conduction to external surfaces or cooling fins, eliminating the need for active cooling components such as pumps, valves, and control systems. The system self-regulates based on temperature gradients without requiring external control.

Solution Approach 1:

The patent segments the electrical line into modular components: conductors, insulators, and integrated heat dissipators. Each component can be manufactured separately using standard industrial processes and then assembled into complete line assemblies. The heat dissipators can be attached to conductors through various joining methods (welding, bonding, or mechanical attachment), enabling flexible manufacturing and quality control suitable for mass production.

AI summary

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.
