Abstract

A wire harness includes a conductive first wiring material, wired to a vehicle, and a second wiring material wired to the vehicle in a state where at least a part of the second wiring material is bundled with the first wiring material. The second wiring material has a flow passage formed therein through which a liquid can flow.

First claim

What is claimed is:

1. A wire harness comprising
a conductive first wiring material wired to a vehicle;
a second wiring material wired to the vehicle in a state where at least a part of the second wiring material is bundled with the first wiring material, and having a flow passage formed therein through which a liquid can flow; and
a sheath material that bundles the first wiring material and the second wiring material, wherein
the second wiring material and the sheath material are integrally formed.

2. A wire harness comprising:
a conductive first wiring material wired to a vehicle; and
a second wiring material wired to the vehicle in a state where at least a part of the second wiring material is bundled with the first wiring material, and having a flow passage formed therein through which a liquid can flow,
wherein the second wiring material constitutes a circulation path that connects a heat source unit that generates heat and a heat consumption unit that consumes heat,
wherein the liquid is a heat exchange medium that circulates through the circulation path constituted by the second wiring material and exchanges heat in the heat source unit and the heat consumption unit, and
wherein the second wiring material further constitutes the circulation path connected to the heat accumulation unit that accumulates heat.

3. The wire harness according to claim 1 , wherein
the sheath material includes a first accommodation space into which the first wiring material is inserted, and a second accommodation space which is partitioned from the first accommodation space and into which the second wiring material is inserted.

4. A wire harness comprising:
a conductive first wiring material wired to a vehicle;
a second wiring material wired to the vehicle in a state where at least a part of the second wiring material is bundled with the first wiring material, and having a flow passage formed therein through which a liquid can flow; and
an external connection part capable of connecting the second wiring material and an external device for the vehicle.

5. The wire harness according to claim 1 , wherein
the second wiring material constitutes a circulation path that connects a heat source unit that generates heat and a heat consumption unit that consumes heat, and
the liquid is a heat exchange medium that circulates through the circulation path constituted by the second wiring material and exchanges heat in the heat source unit and the heat consumption unit.

6. The wire harness according to claim 1 , wherein
the first wiring material includes a power supply line for power supply and a communication line for signal communication.

7. The wire harness according to claim 3 , wherein
the second wiring material constitutes a circulation path that connects a heat source unit that generates heat and a heat consumption unit that consumes heat, and
the liquid is a heat exchange medium that circulates through the circulation path constituted by the second wiring material and exchanges heat in the heat source unit and the heat consumption unit.

8. The wire harness according to claim 3 , further comprising:
an external connection part capable of connecting the second wiring material and an external device for the vehicle.

9. The wire harness according to claim 5 , wherein
the second wiring material further constitutes the circulation path connected to the heat accumulation unit that accumulates heat.

10. The wire harness according to claim 1 , wherein
the second wiring material constitutes a supply path that connects a storage unit that stores the liquid and a injecting unit that injects the liquid to a cleaning target portion, and
the liquid is a cleaning liquid supplied from the storage unit to the injecting unit via the supply path constituted by the second wiring material.

11. The wire harness according to claim 1 , further comprising:
an external connection part capable of connecting the second wiring material and an external device for the vehicle.

12. The wire harness according to claim 3 , wherein
the second wiring material constitutes a supply path that connects a storage unit that stores the liquid and a injecting unit that injects the liquid to a cleaning target portion, and
the liquid is a cleaning liquid supplied from the storage unit to the injecting unit via the supply path constituted by the second wiring material.
